技术领域technical field

本发明涉及照明装置。The present invention relates to lighting devices.

背景技术Background technique

使用了发光二极管(LED)这样的发光元件的照明装置正被广泛使用。若发光元件的温度由于发光元件的发热而变高，则能量效率下降，或者发光元件的寿命变短。因此，期望使发光元件的热耗散的散热性良好，以避免发光元件的温度变高。特别是，工厂、仓库、体育馆、竞技设施等的设置在较高的天花板上的高天花板用照明装置被放置在气温较高的环境中，因此发光元件的冷却变得更重要。Lighting devices using light-emitting elements such as light-emitting diodes (LEDs) are widely used. When the temperature of the light-emitting element increases due to the heat generation of the light-emitting element, the energy efficiency decreases, or the life of the light-emitting element decreases. Therefore, it is desirable to improve the heat dissipation properties of the heat dissipation of the light-emitting element so as to prevent the temperature of the light-emitting element from increasing. In particular, lighting devices for high ceilings installed on high ceilings such as factories, warehouses, gymnasiums, and sports facilities are placed in environments with high air temperature, so cooling of light-emitting elements becomes more important.

FIG. 2 is a perspective view of the lighting device 1A according to Embodiment 1 as viewed obliquely from below. 3 is a cross-sectional side view of the lighting device 1A according to the first embodiment. 4 is a cross-sectional view of the power supply device 7 included in the lighting device 1A according to the first embodiment. FIG. 5 is a functional block diagram of the lighting device 1A according to the first embodiment. The lighting device 1A of Embodiment 1 shown in these figures is installed on the ceiling and irradiates the light downward, so that it can be preferably used for the purpose of illuminating the space lower than the lighting device 1A. In the following description, the upward and downward directions are determined based on the posture when the lighting device 1A is used. The lighting device 1A can be suitably used, for example, as a device that emits light beams ranging from several thousand lumens to tens of thousands of lumens. The lighting device 1A is particularly suitable for use by being installed on high ceilings in factories, warehouses, gymnasiums, sports facilities, and the like.

照明装置1A具备基座2、发光元件3、散热片4、冷却风扇6以及电源装置7。如图1及图3所示，基座2整体上具有实质上为板状的形状。基座2具备上表面及下表面。在照明装置1A的使用时，基座2的上表面及下表面实质上水平。在本实施方式中，从与基座2垂直的方向观察时的基座2的形状为圆形。作为变形例，从与基座2垂直的方向观察时的基座2的形状也可以是长方形或正方形。The lighting device 1A includes a base 2 , a light-emitting element 3 , a heat sink 4 , a cooling fan 6 , and a power supply device 7 . As shown in FIGS. 1 and 3 , the base 2 has a substantially plate-like shape as a whole. The base 2 has an upper surface and a lower surface. When the lighting device 1A is used, the upper surface and the lower surface of the base 2 are substantially horizontal. In the present embodiment, the shape of the base 2 when viewed from the direction perpendicular to the base 2 is circular. As a modification, the shape of the base 2 when viewed from the direction perpendicular to the base 2 may be a rectangle or a square.

在基座2的周缘部安装有环11。环11具有沿着基座2的周缘部的圆环状的形状。A ring 11 is attached to the peripheral edge of the base 2 . The ring 11 has an annular shape along the peripheral edge of the base 2 .

如图2所示，在基座2的下方配置有多个发光元件3。发光元件3从照明装置1A向下照射光。本实施方式中的发光元件3具备发光二极管(LED)。发光元件3设置成能够向基座2的下表面导热。由发光元件3产生的热向基座2导热。发光元件3也可以经由导热性材料与基座2的下表面接触。在下表面安装有发光元件3的光源基板(省略图示)的上表面也可以直接或经由导热性材料与基座2的下表面接触。导热性材料例如可以是导热性油脂、导热性片材、导热性粘接剂、导热性双面粘胶带中的任一种。安装有发光元件3的光源基板和基座2也可以一体地形成。As shown in FIG. 2 , a plurality of light-emitting elements 3 are arranged below the base 2 . The light-emitting element 3 emits light downward from the lighting device 1A. The light-emitting element 3 in this embodiment includes a light-emitting diode (LED). The light emitting element 3 is provided so as to be able to conduct heat to the lower surface of the base 2 . The heat generated by the light emitting element 3 is conducted to the base 2 . The light-emitting element 3 may also be in contact with the lower surface of the base 2 via a thermally conductive material. The upper surface of the light source substrate (not shown) having the light-emitting element 3 mounted on the lower surface may be in contact with the lower surface of the base 2 directly or via a thermally conductive material. The thermally conductive material may be, for example, any of a thermally conductive grease, a thermally conductive sheet, a thermally conductive adhesive, and a thermally conductive double-sided adhesive tape. The light source substrate on which the light emitting element 3 is mounted and the base 2 may be integrally formed.

作为发光元件3，例如可以使用表面安装型LED封装、炮弹型LED封装、带配光透镜的LED封装、芯片级封装的LED、板上芯片(COB)型的LED封装中的至少一种。另外，发光元件3不限于具备LED，例如也可以具备有机电致发光(EL)元件、半导体激光器等。As the light-emitting element 3 , at least one of a surface mount type LED package, a cannonball type LED package, an LED package with a light distribution lens, a chip-scale packaged LED, and a chip-on-board (COB) type LED package can be used, for example. In addition, the light-emitting element 3 is not limited to including an LED, and may include, for example, an organic electroluminescence (EL) element, a semiconductor laser, or the like.

在基座2的上方配置有多个散热片4。基座2及散热片4通过使由发光元件3产生的热向周围的空气耗散来冷却发光元件3。基座2及散热片4相当于散热器。散热片4从基座2的上表面突出。散热片4与基座2的上表面垂直。本实施方式中的散热片4具有板状的形状。由发光元件3产生的热向基座2导热，从基座2进一步向散热片4导热。热从基座2及散热片4的表面向周围的空气耗散。通过利用基座2及散热片4增大散热器的表面积，能够使由发光元件3产生的热高效地耗散。结果，能够降低发光元件3的温度，因此能够提高发光元件3的能量效率即发光效率，并且能够延长发光元件3的寿命。作为变形例，也可以具备使热从基座2向散热片4移动的热管。A plurality of cooling fins 4 are arranged above the base 2 . The base 2 and the heat sink 4 cool the light-emitting element 3 by dissipating the heat generated by the light-emitting element 3 to the surrounding air. The base 2 and the heat sink 4 correspond to a heat sink. The heat sink 4 protrudes from the upper surface of the base 2 . The heat sink 4 is perpendicular to the upper surface of the base 2 . The heat sink 4 in this embodiment has a plate-like shape. The heat generated by the light-emitting element 3 is conducted to the base 2 , and is further conducted from the base 2 to the heat sink 4 . Heat is dissipated from the surfaces of the base 2 and the fins 4 to the surrounding air. By increasing the surface area of the heat sink by the base 2 and the heat sink 4, the heat generated by the light emitting element 3 can be efficiently dissipated. As a result, since the temperature of the light emitting element 3 can be lowered, the energy efficiency of the light emitting element 3 , that is, the luminous efficiency can be improved, and the life of the light emitting element 3 can be extended. As a modified example, a heat pipe that moves heat from the base 2 to the fins 4 may be provided.

在从与基座2垂直的方向观察时，多个散热片4配置成放射状。多个散热片4分别从基座2的中央区域向径向外侧延伸。作为变形例，也可以将多个板状的散热片4相互平行地配置。作为其他变形例，散热片4也可以是具有销形的形状的销翅片。When viewed from a direction perpendicular to the base 2 , the plurality of fins 4 are radially arranged. The plurality of fins 4 each extend radially outward from the central region of the base 2 . As a modified example, a plurality of plate-shaped fins 4 may be arranged in parallel with each other. As another modification, the heat sink 4 may be a pin fin having a pin shape.

基座2及散热片4优选由轻量且导热系数高的金属材料制成。作为这样的金属材料，例如可列举出铝、铝类合金、铜类合金、不锈钢等。本实施方式的散热片4是将金属薄板折弯而制作的。由此，能够实现轻量化。在本实施方式中，相邻的两片散热片4通过折弯一张金属薄板而制成。如图1所示，由一张金属薄板形成的相邻的两片散热片4的基端部经由固定部4a相连。固定部4a固定于基座2。此外，将散热片4固定于基座2的方法例如可以是铆接固定、螺纹紧固、粘接、焊接、钎焊等任何方法。另外，也可以通过例如压铸方式等将基座2及散热片4一体成形。The base 2 and the heat sink 4 are preferably made of a lightweight and high thermal conductivity metal material. Examples of such metal materials include aluminum, aluminum-based alloys, copper-based alloys, stainless steel, and the like. The heat sink 4 of this embodiment is produced by bending a thin metal plate. Thereby, weight reduction can be achieved. In this embodiment, two adjacent fins 4 are formed by bending a thin metal plate. As shown in FIG. 1 , the base ends of two adjacent fins 4 formed of one sheet of metal thin plate are connected to each other via a fixing portion 4a. The fixing portion 4 a is fixed to the base 2 . In addition, the method of fixing the heat sink 4 to the base 2 may be any method, such as caulking, screwing, bonding, welding, and brazing, for example. Alternatively, the base 2 and the heat sink 4 may be integrally formed by, for example, die casting.

如图1所示，照明装置1A具备主体支承件9。主体支承件9支承照明装置1A的主体部。照明装置1A的主体部包括基座2、发光元件3、多个散热片4、冷却风扇6、电源装置7、电源支承件8、环11以及风扇支承件12。主体支承件9具有细长的板状的固定部9a和从固定部9a的两端突出的一对臂部9b。各臂部9b在与固定部9a的长度方向垂直的方向上突出。在各臂部9b的前端部分形成有弯曲成圆弧状的长孔9c。主体支承件9能够相对旋转地连结于照明装置1A的主体部。各臂部9b能够相对旋转地连结于环11。环11具有从周向的两个部位向上方突出的突出部11a。各臂部9b与环11的突出部11a连结。螺栓10通过主体支承件9的臂部9b的长孔9c而插入到设置于环11的突出部11a的螺纹孔中。主体支承件9的旋转轴RA的位置是沿着长孔9c的圆弧的圆的中心的位置。作为变形例，螺栓10的位置也可以是主体支承件9的旋转轴RA的位置。旋转轴RA与基座2平行。在从与基座2垂直的方向观察时，旋转轴RA通过基座2的中心。As shown in FIG. 1 , the lighting device 1A includes a main body support 9 . The main body support 9 supports the main body of the lighting device 1A. The main body portion of the lighting device 1A includes a base 2 , a light-emitting element 3 , a plurality of heat sinks 4 , a cooling fan 6 , a power supply unit 7 , a power supply support 8 , a ring 11 , and a fan support 12 . The main body support 9 has an elongated plate-shaped fixing portion 9a and a pair of arm portions 9b protruding from both ends of the fixing portion 9a. Each arm portion 9b protrudes in a direction perpendicular to the longitudinal direction of the fixing portion 9a. A long hole 9c curved in an arc shape is formed at the tip end portion of each arm portion 9b. The main body support 9 is connected to the main body portion of the lighting device 1A so as to be relatively rotatable. Each arm portion 9b is connected to the ring 11 so as to be relatively rotatable. The ring 11 has protrusions 11a that protrude upward from two locations in the circumferential direction. Each arm portion 9b is connected to the protruding portion 11a of the ring 11 . The bolt 10 is inserted into the screw hole provided in the protruding portion 11 a of the ring 11 through the long hole 9 c of the arm portion 9 b of the main body support 9 . The position of the rotation axis RA of the main body support 9 is the position of the center of the circle along the arc of the long hole 9c. As a modification, the position of the bolt 10 may be the position of the rotation axis RA of the main body support 9 . The rotation axis RA is parallel to the base 2 . The rotation axis RA passes through the center of the base 2 when viewed from a direction perpendicular to the base 2 .

在设置照明装置1A时，通过紧固螺栓10，主体支承件9以不相对旋转的方式固定于照明装置1A的主体部。螺栓10是能够将主体支承件9以不相对旋转的方式固定于照明装置1A的主体部的固定单元的例子。When the lighting device 1A is installed, the main body support 9 is fixed to the main body portion of the lighting device 1A so as not to rotate relatively by tightening the bolts 10 . The bolt 10 is an example of a fixing unit capable of fixing the main body support 9 to the main body of the lighting device 1A without relative rotation.

主体支承件9的固定部9a固定于建筑物的天花板或梁等的安装面。在固定部9a形成有用于穿过该固定用的螺栓的孔。在图1至图3的状态下，固定部9a与基座2平行。在安装面为水平的情况下，在该状态下主体支承件9的固定部9a固定于安装面。由此，以基座2成为水平的适当的姿势固定照明装置1A。与此相对，在安装面为相对于水平面倾斜的倾斜面的情况下，能够改变主体支承件9相对于照明装置1A的主体部的角度，以使主体支承件9的臂部9b与该倾斜面垂直。即，当松开螺栓10时，主体支承件9能够以旋转轴RA为中心旋转，能够使主体支承件9相对于照明装置1A的主体部倾斜。当主体支承件9相对于照明装置1A的主体部倾斜时，螺栓10相对于长孔9c相对地移动。通过再次紧固螺栓10，能够将主体支承件9固定于该倾斜角度的位置。这样，在安装面为倾斜面的情况下，能够以主体支承件9的臂部9b与该倾斜面垂直的方式使固定部9a倾斜。由此，能够以适当的姿势设置照明装置1A。The fixing part 9a of the main body support 9 is fixed to the installation surface, such as a ceiling of a building or a beam. The fixing|fixed part 9a is formed with the hole for passing the bolt for this fixing. In the states of FIGS. 1 to 3 , the fixing portion 9 a is parallel to the base 2 . When the mounting surface is horizontal, the fixing portion 9a of the main body support 9 is fixed to the mounting surface in this state. Thereby, the lighting device 1A is fixed in an appropriate posture in which the base 2 is horizontal. On the other hand, when the attachment surface is an inclined surface inclined with respect to the horizontal plane, the angle of the main body support 9 with respect to the main body of the lighting device 1A can be changed so that the arm portion 9b of the main body support 9 is aligned with the inclined surface. vertical. That is, when the bolt 10 is loosened, the main body support 9 can be rotated about the rotation axis RA, and the main body support 9 can be inclined with respect to the main body of the lighting device 1A. When the main body support 9 is inclined with respect to the main body portion of the lighting device 1A, the bolt 10 relatively moves with respect to the long hole 9c. By tightening the bolts 10 again, the main body support 9 can be fixed at the inclined angle position. In this way, when the attachment surface is an inclined surface, the fixed portion 9a can be inclined so that the arm portion 9b of the main body support 9 is perpendicular to the inclined surface. Thereby, the lighting device 1A can be installed in an appropriate posture.

如图3所示，基座中心线BC是通过基座2的中心且与基座2垂直的直线。电源中心线PC是通过电源框体7d的中心且与基座2垂直的直线。电源中心线PC相对于基座中心线BC而位置偏移。图3是沿包含基座中心线BC及电源中心线PC的平面剖切的剖视图。图3是沿与主体支承件9的旋转轴RA垂直的平面剖切的剖视图。冷却风扇6的中心线与基座中心线BC一致。As shown in FIG. 3 , the base center line BC is a straight line passing through the center of the base 2 and perpendicular to the base 2 . The power supply center line PC is a straight line passing through the center of the power supply housing 7d and perpendicular to the base 2 . The power supply center line PC is offset with respect to the base center line BC. 3 is a cross-sectional view taken along a plane including the base centerline BC and the power supply centerline PC. FIG. 3 is a cross-sectional view taken along a plane perpendicular to the rotation axis RA of the main body support 9 . The centerline of the cooling fan 6 coincides with the base centerline BC.

当冷却风扇6运转时，如下所述。冷却风扇6产生的气流由图3中的带有箭头的曲线示意性地表示。从冷却风扇6向下吹出气流。气流通过散热片4之间而吹到基座2的上表面。吹到基座2上的气流改变方向。吹到基座2上的气流从基座2的中央区域通过散热片4之间向基座2的外周侧呈放射状地流动。这样，冷却风扇6产生的气流沿着基座2的上表面及散热片4的表面流动，从而能够使发光元件3的热更高效地耗散，能够进一步降低发光元件3的温度。特别是，根据本实施方式，通过将散热片4配置成放射状，能够将来自冷却风扇6的气流高效地向基座2的外周侧排出。因此，空气能够顺畅地流动，冷却效率进一步提高。When the cooling fan 6 operates, it is as follows. The airflow generated by the cooling fan 6 is schematically represented by the curve with arrows in FIG. 3 . The airflow is blown downward from the cooling fan 6 . The airflow is blown to the upper surface of the base 2 by passing between the fins 4 . The airflow on the base 2 changes direction. The airflow blown onto the susceptor 2 flows radially toward the outer peripheral side of the susceptor 2 from the central region of the susceptor 2 through between the fins 4 . In this way, the airflow generated by the cooling fan 6 flows along the upper surface of the base 2 and the surface of the heat sink 4 , so that the heat of the light emitting element 3 can be dissipated more efficiently, and the temperature of the light emitting element 3 can be further reduced. In particular, according to the present embodiment, by arranging the fins 4 radially, the airflow from the cooling fan 6 can be efficiently discharged to the outer peripheral side of the base 2 . Therefore, the air can flow smoothly, and the cooling efficiency is further improved.

另外，冷却风扇6产生的气流的一部分吹到电源框体7d的表面。由此，能够促进热从电源框体7d的表面耗散，能够高效地冷却电源装置7。结果，能够更可靠地防止电源装置7的效率的下降。通过使电源中心线PC相对于基座中心线BC而位置偏移，能够得到以下的效果。配置成从冷却风扇6向基座2及散热片4的气流不易被电源框体7d妨碍。由冷却风扇6产生的气流的通气阻力小，因此能够增大风量。因此，能够提高基座2及散热片4的冷却效率。这样，根据本实施方式，通过由冷却风扇6产生对流，能够高效地同时冷却成为发热源的发光元件3及电源装置7这双方。特别是，在本实施方式中，基座中心线BC通过电源框体7d的外侧。由此，能够更可靠地防止从冷却风扇6向基座2及散热片4的气流被电源框体7d妨碍。因此，能够进一步减小由冷却风扇6产生的气流的通气阻力，能够进一步增大风量。In addition, part of the airflow generated by the cooling fan 6 is blown onto the surface of the power supply housing 7d. Thereby, heat dissipation from the surface of the power supply housing 7d can be promoted, and the power supply device 7 can be efficiently cooled. As a result, the reduction in the efficiency of the power supply device 7 can be prevented more reliably. By shifting the position of the power supply center line PC with respect to the base center line BC, the following effects can be obtained. The air flow from the cooling fan 6 to the base 2 and the heat sink 4 is arranged so that the power supply housing 7d is not easily hindered. Since the ventilation resistance of the air flow generated by the cooling fan 6 is small, the air volume can be increased. Therefore, the cooling efficiency of the base 2 and the heat sink 4 can be improved. As described above, according to the present embodiment, by generating convection by the cooling fan 6 , it is possible to efficiently cool both the light-emitting element 3 and the power supply device 7 serving as heat sources at the same time. In particular, in the present embodiment, the base center line BC passes through the outside of the power supply housing 7d. Thereby, the airflow from the cooling fan 6 to the base 2 and the heat sink 4 can be prevented more reliably from being obstructed by the power supply housing 7d. Therefore, the ventilation resistance of the airflow generated by the cooling fan 6 can be further reduced, and the airflow volume can be further increased.

图4是在与图3相同的位置剖切的剖视图。如图4所示，电源框体7d的第一侧壁7h与基座中心线BC的距离小于第二侧壁7i与基座中心线BC之间的距离。越靠近基座中心线BC的位置，冷却风扇6产生的气流有越快的倾向。因此，第一侧壁7h与较快的气流碰撞，因此易于被冷却。根据本实施方式，能够使从电气元件7j产生的热向该易于被冷却的第一侧壁7h导热。因此，能够降低电气元件7j的温度，因此有利于电源装置7的效率提高。另外，根据本实施方式，由于具备设置于第一侧壁7h的外侧的散热器7m，从而散热器7m与较快的气流碰撞。因此，能够进一步降低电源装置7的温度。但是，也可以没有散热器7m。FIG. 4 is a cross-sectional view cut at the same position as FIG. 3 . As shown in FIG. 4 , the distance between the first side wall 7h of the power supply frame 7d and the center line BC of the base is smaller than the distance between the second side wall 7i and the center line BC of the base. The closer to the base centerline BC, the faster the airflow generated by the cooling fan 6 tends to be. Therefore, the first side wall 7h collides with the faster airflow, and thus is easily cooled. According to this embodiment, the heat generated from the electrical element 7j can be conducted to the easily cooled first side wall 7h. Therefore, the temperature of the electric components 7j can be lowered, which contributes to the improvement of the efficiency of the power supply device 7 . Moreover, according to this embodiment, since the heat sink 7m provided in the outer side of the 1st side wall 7h is provided, the heat sink 7m collides with a quick airflow. Therefore, the temperature of the power supply device 7 can be further lowered. However, the radiator 7m may not be provided.

如上所述，气流在散热片4之间沿基座2的半径方向流动，并向基座2的外周侧排出。若在散热片4的外侧存在构造物，则该气流难以流动。因此，在电源支承件8的腿部8a的位置，从散热片4之间向外侧排出的气流有可能难以流动。As described above, the airflow flows in the radial direction of the base 2 between the fins 4 and is discharged to the outer peripheral side of the base 2 . If there is a structure on the outer side of the fins 4 , it is difficult for the airflow to flow. Therefore, at the position of the leg portion 8 a of the power source support 8 , the airflow discharged to the outside from between the fins 4 may be difficult to flow.

如图1所示，主体支承件9的各臂部9b位于电源支承件8的各腿部8a的外侧。由此，能够得到以下的效果。能够防止主体支承件9的臂部9b妨碍从散热片4之间向外侧排出的气流。假如主体支承件9的臂部9b配置在与电源支承件8的腿部8a不同的位置，则主体支承件9的臂部9b有可能妨碍从散热片4之间向外侧排出的气流。与此相对，根据本实施方式，主体支承件9的臂部9b不会妨碍从散热片4之间向外侧排出的气流，从而能够进一步提高冷却性能。As shown in FIG. 1 , each arm portion 9 b of the main body support 9 is located outside each leg portion 8 a of the power supply support 8 . Thereby, the following effects can be obtained. The arm portion 9 b of the main body support 9 can be prevented from obstructing the airflow discharged to the outside from between the fins 4 . If the arm portion 9b of the main body support 9 is disposed at a different position from the leg portion 8a of the power supply support 8, the arm portion 9b of the main body support 9 may obstruct the airflow discharged from between the fins 4 to the outside. On the other hand, according to the present embodiment, the arm portion 9b of the main body support 9 does not interfere with the airflow discharged to the outside from between the fins 4, so that the cooling performance can be further improved.

作为变形例，也可以代替本实施方式那样的轴流风扇，使用离心风扇、斜流风扇、横流风扇等作为冷却风扇6。冷却风扇6只要是成为强制风冷方式的风扇，则可以是任意的风扇。As a modified example, a centrifugal fan, a diagonal flow fan, a cross flow fan, or the like may be used as the cooling fan 6 instead of the axial flow fan as in the present embodiment. The cooling fan 6 may be any fan as long as it is a fan of a forced air cooling system.

The light-emitting element 3 is turned on by causing a current to flow through the light-emitting element 3 from the power supply device 7 via the cable 13 .

The translucent cover 15 is arranged below the base 2 and is fixed to the ring 11 . The translucent cover 15 entirely covers the region where the plurality of light emitting elements 3 are arranged. The light from the light-emitting element 3 passes through the translucent cover 15 and is irradiated to the outside of the lighting device 1A. The light-transmitting cover 15 reliably protects the light-emitting element 3 from dirt, water, or the like. By providing the light-transmitting cover 15, deterioration or failure of the light-emitting element 3 can be reliably prevented. The light-transmitting cover 15 may be made of a transparent material that regularly transmits light (Japanese: forward transmission). Alternatively, the light-transmitting cover 15 may diffusely transmit light. The light-transmitting cover 15 can be made of, for example, a resin material such as polycarbonate resin, acrylic resin, and polystyrene resin, or a glass material. The surface of the translucent cover 15 may be subjected to a coating treatment such as a hard coating treatment which is advantageous in suppressing deterioration. The light-transmitting cover 15 may also be waterproof. A waterproof sealing material or an adhesive may be provided at the joint portion between the translucent cover 15 and the ring 11 . The sealing material or the adhesive may be formed of, for example, a soft resin material, a silicone-based sealing material, a rubber-based material, or the like.

如图5所示，在本实施方式中，电源装置7除了光源驱动电路7a及风扇驱动电路7b以外，还具备控制部7e。控制部7e经由光源驱动电路7a驱动光源部17。控制部7e经由风扇驱动电路7b驱动冷却风扇6。控制部7e具备处理器7f及存储器7g。典型地，控制部7e具有包括微型计算机的结构。控制部7e设置在电源框体7d内。控制部7e设置于电子电路基板7c。作为变形例，构成控制部7e的电子电路基板和构成光源驱动电路7a及风扇驱动电路7b的电子电路基板也可以分离。As shown in FIG. 5 , in the present embodiment, the power supply device 7 includes a control unit 7e in addition to the light source drive circuit 7a and the fan drive circuit 7b. The control unit 7e drives the light source unit 17 via the light source drive circuit 7a. The control unit 7e drives the cooling fan 6 via the fan drive circuit 7b. The control unit 7e includes a processor 7f and a memory 7g. Typically, the control section 7e has a structure including a microcomputer. The control unit 7e is provided in the power supply housing 7d. The control unit 7e is provided on the electronic circuit board 7c. As a modification, the electronic circuit board constituting the control unit 7e and the electronic circuit board constituting the light source driving circuit 7a and the fan driving circuit 7b may be separated.

光源部17由多个发光元件3构成。在图5的例子中，在光源部17中，多个发光元件3以串联方式连接。代替该例，光源部17中的多个发光元件3可以以并联方式连接，也可以以串并联方式连接。The light source unit 17 is composed of a plurality of light emitting elements 3 . In the example of FIG. 5 , in the light source unit 17 , the plurality of light emitting elements 3 are connected in series. Instead of this example, the plurality of light emitting elements 3 in the light source unit 17 may be connected in parallel, or may be connected in series and parallel.

光源驱动电路7a使电流流过光源部17的发光元件3。光源驱动电路7a具备将从照明装置1A的外部的交流电源100供给的交流电力转换为直流电力的电源电路。电源电路例如也可以具备使用了半导体开关元件的开关电源。典型地，交流电源100是商用电源。光源驱动电路7a根据来自控制部7e的指令，调整流过发光元件3的电流，从而能够调整从发光元件3发出的光束。由此，能够调整照明装置1A的照度及亮度。The light source drive circuit 7 a causes current to flow through the light emitting element 3 of the light source unit 17 . The light source drive circuit 7a includes a power supply circuit that converts AC power supplied from an AC power supply 100 external to the lighting device 1A into DC power. The power supply circuit may include, for example, a switching power supply using semiconductor switching elements. Typically, the AC power source 100 is a commercial power source. The light source drive circuit 7a can adjust the current flowing through the light-emitting element 3 according to the command from the control unit 7e, so that the light beam emitted from the light-emitting element 3 can be adjusted. Thereby, the illuminance and brightness of the lighting device 1A can be adjusted.

以下，将与光源部17的发光元件3的温度相关的温度称为“光源温度”。光源温度传感器18检测光源温度。光源温度传感器18是光源温度检测单元的例子。基座2或散热片4的温度与发光元件3的温度相关。因此，通过将光源温度传感器18安装于基座2或散热片4，能够检测光源温度。或者也可以在发光元件3自身上安装光源温度传感器18。由光源温度传感器18检测出的光源温度的信息被输入到控制部7e。控制部7e能够基于由光源温度传感器18检测出的光源温度的信息，单独地控制光源驱动电路7a及风扇驱动电路7b。Hereinafter, the temperature related to the temperature of the light emitting element 3 of the light source unit 17 is referred to as "light source temperature". The light source temperature sensor 18 detects the light source temperature. The light source temperature sensor 18 is an example of a light source temperature detection unit. The temperature of the base 2 or the heat sink 4 is related to the temperature of the light emitting element 3 . Therefore, the light source temperature can be detected by attaching the light source temperature sensor 18 to the base 2 or the heat sink 4 . Alternatively, the light source temperature sensor 18 may be mounted on the light emitting element 3 itself. The information of the light source temperature detected by the light source temperature sensor 18 is input to the control part 7e. The control part 7e can individually control the light source drive circuit 7a and the fan drive circuit 7b based on the information of the light source temperature detected by the light source temperature sensor 18.

风扇驱动电路7b根据来自控制部7e的指令，向冷却风扇6的电动机供给电力。风扇驱动电路7b通过调整向冷却风扇6的电动机供给的电力的电流、电压以及频率中的至少一个，能够调整冷却风扇6的旋转速度。以下，将冷却风扇6的旋转速度称为“风扇速度”。检测风扇速度的风扇速度传感器19设置于冷却风扇6。风扇速度传感器19是风扇速度检测单元的例子。The fan drive circuit 7b supplies electric power to the motor of the cooling fan 6 in accordance with a command from the control unit 7e. The fan drive circuit 7 b can adjust the rotational speed of the cooling fan 6 by adjusting at least one of the current, voltage, and frequency of the electric power supplied to the motor of the cooling fan 6 . Hereinafter, the rotational speed of the cooling fan 6 is referred to as "fan speed". The cooling fan 6 is provided with a fan speed sensor 19 that detects the fan speed. The fan speed sensor 19 is an example of a fan speed detection unit.

在以下的说明中，将向光源部17的发光元件3供给的直流电流的电流值称为“光源电流”。由风扇速度传感器19检测出的风扇速度的信息经由风扇驱动电路7b被输入到控制部7e。控制部7e通过基于由风扇速度传感器19检测出的风扇速度的信息来控制光源驱动电路7a，能够控制光源电流。控制部7e通过基于由光源温度传感器18检测出的光源温度的信息来控制光源驱动电路7a，能够控制光源电流。并且，控制部7e通过基于该光源温度的信息来控制风扇驱动电路7b，能够控制冷却风扇6的风扇速度。In the following description, the current value of the DC current supplied to the light-emitting element 3 of the light source unit 17 is referred to as "light source current". The information of the fan speed detected by the fan speed sensor 19 is input to the control part 7e via the fan drive circuit 7b. The control unit 7e can control the light source current by controlling the light source drive circuit 7a based on the information of the fan speed detected by the fan speed sensor 19 . The control unit 7e can control the light source current by controlling the light source drive circuit 7a based on the information of the light source temperature detected by the light source temperature sensor 18 . Then, the control unit 7e can control the fan speed of the cooling fan 6 by controlling the fan drive circuit 7b based on the light source temperature information.

图6是表示发光元件3发出的光束、光源电流、光源温度的关系的图。如图6所示，发光元件3具有以下那样的特性。若增加光源电流，则光束增加。在光源电流相等的情况下，与光源温度高的条件相比，在光源温度低的条件下，光束变大。为了得到规定的光束，需要控制光源电流，并且控制光源温度。FIG. 6 is a graph showing the relationship between the light flux emitted by the light emitting element 3, the light source current, and the light source temperature. As shown in FIG. 6 , the light-emitting element 3 has the following characteristics. If the light source current is increased, the beam increases. When the light source current is the same, the light beam becomes larger under the condition that the light source temperature is low than under the condition that the light source temperature is high. In order to obtain a predetermined light beam, it is necessary to control the light source current and control the light source temperature.

在本实施方式中，基于光源温度的信息，控制部7e控制光源驱动电路7a，从而能够控制光源电流和光源温度这两者。以下，对控制的例子进行说明。In the present embodiment, the control unit 7e controls the light source drive circuit 7a based on the information of the light source temperature, so that both the light source current and the light source temperature can be controlled. Hereinafter, an example of control will be described.

(例1)如上所述，为了得到规定的光束，需要控制光源电流和光源温度这两者。例如，在将光源驱动电路7a控制成光源电流恒定的情况下，光束根据光源温度的变化而变化，因此需要使光源温度恒定。在该情况下，控制部7e利用风扇驱动电路7b控制冷却风扇6的风扇速度，以使由光源温度传感器18检测出的光源温度恒定，从而能够使光源温度恒定。也就是说，控制部7e控制光源驱动电路7a及风扇驱动电路7b，以使光源电流恒定且光源温度恒定，从而能够提供可得到恒定的光束的照明装置1A。通过得到恒定的光束，能够得到恒定的照度及亮度。作为变形例，控制部7e也可以控制冷却风扇6的开/关，以使由光源温度传感器18检测出的光源温度恒定。(Example 1) As described above, in order to obtain a predetermined light flux, it is necessary to control both the light source current and the light source temperature. For example, when the light source drive circuit 7a is controlled so that the light source current is constant, the light beam changes according to the change in the temperature of the light source, so the temperature of the light source needs to be kept constant. In this case, the control unit 7e controls the fan speed of the cooling fan 6 by the fan drive circuit 7b so that the light source temperature detected by the light source temperature sensor 18 is constant, thereby making the light source temperature constant. That is, the control unit 7e controls the light source driving circuit 7a and the fan driving circuit 7b so that the light source current is constant and the light source temperature is constant, thereby providing the lighting device 1A that can obtain a constant light beam. By obtaining a constant light beam, constant illuminance and brightness can be obtained. As a modified example, the control unit 7e may control the on/off of the cooling fan 6 so that the light source temperature detected by the light source temperature sensor 18 becomes constant.

(例2)作为另一例，设想在光源温度为规定温度以下的范围内照明装置1A点亮的情况。该规定温度是指在发光元件3能够使用的温度范围内，并且在使发光元件3以该规定温度长时间点亮的情况下能够得到所期望的光束，能够达到所期望的寿命时间的温度。在光源温度为规定温度以下的范围内照明装置1A点亮的情况下，控制部7e控制光源驱动电路7a及风扇驱动电路7b，以使光源温度越低则光源电流越低，光源温度越高则光源电流越高，从而能够得到恒定的光束。通过得到恒定的光束，能够得到恒定的照度及亮度。根据该例2，能够减小冷却风扇6的运转时间及风扇速度中的至少一方。结果，能够延长冷却风扇6的寿命，能够进一步提高照明装置1A的可靠性。(Example 2) As another example, it is assumed that the lighting device 1A is turned on in a range where the temperature of the light source is equal to or lower than a predetermined temperature. The predetermined temperature is within the temperature range in which the light-emitting element 3 can be used, and when the light-emitting element 3 is lit at the predetermined temperature for a long time, a desired light flux can be obtained and a desired lifetime can be achieved. When the lighting device 1A is turned on within a range where the light source temperature is equal to or lower than the predetermined temperature, the control unit 7e controls the light source driving circuit 7a and the fan driving circuit 7b so that the lower the light source temperature is, the lower the light source current is, and the higher the light source temperature is, the lower the light source current is. The higher the light source current, the more constant the beam can be obtained. By obtaining a constant light beam, constant illuminance and brightness can be obtained. According to this example 2, at least one of the operation time of the cooling fan 6 and the fan speed can be reduced. As a result, the life of the cooling fan 6 can be extended, and the reliability of the lighting device 1A can be further improved.

在控制部7e经由风扇驱动电路7b进行指令以使冷却风扇6运转的状态下，在由风扇速度传感器19检测出的风扇速度为零或非常低速的情况下，可以认为冷却风扇6由于例如老化或寿命而发生了故障。这样，控制部7e能够检测冷却风扇6的故障、老化或者寿命到期那样的冷却风扇6的异常。In the state where the control unit 7e instructs the cooling fan 6 to operate via the fan drive circuit 7b, and the fan speed detected by the fan speed sensor 19 is zero or very low, it is considered that the cooling fan 6 is caused by, for example, aging or a very low speed. failure occurred during the lifetime. In this way, the control unit 7e can detect an abnormality of the cooling fan 6 such as failure of the cooling fan 6, deterioration, or expiration of its life.

在检测到冷却风扇6的异常的情况下，控制部7e也可以控制光源驱动电路7a，以使与没有冷却风扇6的异常的情况相比光源电流降低。在检测到冷却风扇6的异常的情况下，控制部7e也可以减小光源电流，以使由光源温度传感器18检测出的光源温度达到规定温度以下。通过以上这样设置，在冷却风扇6发生了异常的情况下，能够可靠地防止光源温度大幅上升，因此能够可靠地防止发光元件3的热老化。When the abnormality of the cooling fan 6 is detected, the control part 7e may control the light source drive circuit 7a so that a light source current may be reduced compared with the case where there is no abnormality of the cooling fan 6. FIG. When abnormality of the cooling fan 6 is detected, the control unit 7e may reduce the light source current so that the light source temperature detected by the light source temperature sensor 18 becomes equal to or lower than a predetermined temperature. With the above arrangement, when an abnormality occurs in the cooling fan 6 , the temperature of the light source can be reliably prevented from rising significantly, and thus the thermal degradation of the light-emitting element 3 can be reliably prevented.

控制部7e也可以构成为能够与终端装置60之间进行数据通信。终端装置60构成为用户能够对照明装置1A进行远程操作。控制部7e与终端装置60之间的通信方式可以是有线通信，也可以是无线通信。终端装置60具备用于供用户操作的操作部61和通过显示文字、图形、字符等来通知信息的显示器62。终端装置60能够根据用户操作来向控制部7e发送例如与照明装置1A的点亮、熄灭、调光等有关的指令。例如，操作部61及显示器62可以由触摸屏一体构成。显示器62是通知单元的例子。除了显示器62以外，或者代替显示器62，终端装置60也可以具备例如声音输出装置等其他通知单元。终端装置60也可以固定于房间的墙壁等。终端装置60也可以是能够携带的移动终端。终端装置60与控制部7e也可以能够直接通信。终端装置60和控制部7e也可以经由例如照明控制系统的控制器那样的其他设备或网络而能够间接地进行通信。The control unit 7e may be configured to be capable of data communication with the terminal device 60 . The terminal device 60 is configured so that the user can remotely operate the lighting device 1A. The communication method between the control unit 7e and the terminal device 60 may be wired communication or wireless communication. The terminal device 60 includes an operation unit 61 for a user to operate, and a display 62 for notifying information by displaying characters, figures, characters, and the like. The terminal device 60 can transmit, for example, a command related to the lighting device 1A on, off, dimming, and the like to the control unit 7e in accordance with a user operation. For example, the operation unit 61 and the display 62 may be formed integrally with a touch panel. The display 62 is an example of a notification unit. In addition to the display 62 or instead of the display 62, the terminal device 60 may be provided with other notification means such as, for example, a sound output device. The terminal device 60 may be fixed to the wall of the room or the like. The terminal device 60 may be a portable terminal. The terminal device 60 and the control unit 7e may be able to communicate directly. The terminal device 60 and the control unit 7e may be able to communicate indirectly via another device or network such as a controller of a lighting control system.

控制部7e也可以基于从环境传感器(省略图示)接收到的信息来控制光源驱动电路7a及风扇驱动电路7b，该环境传感器检测与使用照明装置1A的环境或接收来自照明装置1A的光的环境有关的信息。即，控制部7e也可以基于由环境传感器检测出的信息来控制发光元件3的点亮、熄灭、调光等，或者控制冷却风扇6的动作。环境传感器例如可以是检测环境的气温的气温传感器、检测环境的明亮度的明亮度传感器、检测处于环境的人的人感传感器中的至少一个。例如，也可以如下这样设置。The control unit 7e may control the light source drive circuit 7a and the fan drive circuit 7b based on information received from an environment sensor (not shown) that detects an environment in which the lighting device 1A is used or receives light from the lighting device 1A. environment-related information. That is, the control unit 7e may control the lighting, extinguishing, dimming, etc. of the light-emitting element 3, or control the operation of the cooling fan 6 based on the information detected by the environmental sensor. The environment sensor may be, for example, at least one of an air temperature sensor that detects the air temperature of the environment, a brightness sensor that detects the brightness of the environment, and a human sensor sensor that detects a person in the environment. For example, it may be set as follows.

也可以是，通过作为环境传感器的气温传感器检测气温，控制部7e进行控制，以使与气温比较低的情况相比，在气温比较高的情况下冷却风扇6的风扇速度变高。也可以是，通过作为环境传感器的明亮度传感器来检测环境的明亮度，控制部7e增减来自照明装置1A的光输出，以使环境的明亮度恒定。也可以是，在作为环境传感器的人感传感器检测到人的情况下，控制部7e使照明装置1A点亮。也可以是，在人感传感器未检测到人的情况下，控制部7e使照明装置1A减光或熄灭。The air temperature may be detected by an air temperature sensor as an environmental sensor, and the control unit 7e may control the fan speed of the cooling fan 6 to be higher when the air temperature is relatively high than when the air temperature is relatively low. The brightness of the environment may be detected by a brightness sensor serving as an environment sensor, and the control unit 7e may increase or decrease the light output from the lighting device 1A so that the brightness of the environment becomes constant. The control unit 7e may turn on the lighting device 1A when a human is detected by a human-sensing sensor serving as an environmental sensor. The control unit 7e may dim or turn off the lighting device 1A when the human detection sensor does not detect a person.

图7是实施方式1的照明装置1A的变形例所具备的电源装置7A的剖视图。照明装置1A也可以具备图7所示的电源装置7A来代替图3所示的电源装置7。以下，关于具备该电源装置7A的变形例，说明与上述结构的不同点。图7是在与图3相同位置的剖视图。如图7所示，电源装置7A不具备散热器7m。电源装置7A的电源框体7d的内部的布局与电源装置7不同。发热的电气元件7j经由导热性材料7k与电源装置7A的电源框体7d的上壁7p的内表面接触。从电气元件7j产生的热经由导热性材料7k向电源框体7d的上壁7p导热。作为变形例，电气元件7j也可以与上壁7p的内表面直接接触。7 is a cross-sectional view of a power supply device 7A included in a modification of the lighting device 1A of the first embodiment. The lighting device 1A may include the power supply device 7A shown in FIG. 7 in place of the power supply device 7 shown in FIG. 3 . Hereinafter, the difference from the above-described configuration will be described with respect to a modified example including the power supply device 7A. FIG. 7 is a cross-sectional view at the same position as FIG. 3 . As shown in FIG. 7 , the power supply device 7A does not include the heat sink 7m. The layout inside the power supply housing 7d of the power supply device 7A is different from that of the power supply device 7 . The electric component 7j that generates heat is in contact with the inner surface of the upper wall 7p of the power supply housing 7d of the power supply device 7A via the thermally conductive material 7k. The heat generated from the electrical element 7j is conducted to the upper wall 7p of the power supply housing 7d via the thermally conductive material 7k. As a modification example, the electrical element 7j may be in direct contact with the inner surface of the upper wall 7p.

如图3所示，冷却风扇6产生的气流的一部分吹到电源框体7d的上壁7p的外表面。因此，上壁7p易于被冷却。根据图7的变形例，能够使从电气元件7j产生的热向该易于冷却的上壁7p导热。因此，能够降低电气元件7j的温度，因此有利于电源装置7的效率提高。As shown in FIG. 3 , a part of the airflow generated by the cooling fan 6 is blown onto the outer surface of the upper wall 7p of the power supply housing 7d. Therefore, the upper wall 7p is easily cooled. According to the modification of FIG. 7 , the heat generated from the electrical element 7j can be conducted to the easily cooled upper wall 7p. Therefore, the temperature of the electric components 7j can be lowered, which contributes to the improvement of the efficiency of the power supply device 7 .

如图3所示，在本实施方式中，从与基座中心线BC垂直的方向观察，在冷却风扇6与电源框体7d之间形成有空气能够通过的空间。作为变形例，也可以在从与基座中心线BC垂直的方向观察时，冷却风扇6与电源框体7d以无间隙地相接的方式配置。作为变形例，照明装置1A也可以具备多个冷却风扇6。在该情况下，各冷却风扇6的中心的位置也可以配置为以基座中心线BC为中心而旋转对称。As shown in FIG. 3 , in the present embodiment, a space through which air can pass is formed between the cooling fan 6 and the power supply housing 7d when viewed from a direction perpendicular to the base centerline BC. As a modified example, the cooling fan 6 and the power supply housing 7d may be arranged to be in contact with each other without a gap when viewed from a direction perpendicular to the base center line BC. As a modified example, the lighting device 1A may include a plurality of cooling fans 6 . In this case, the position of the center of each cooling fan 6 may be arranged to be rotationally symmetrical about the base center line BC.

实施方式2Embodiment 2

下面，参照图8及图9，对实施方式2进行说明，以与上述实施方式1的不同点为中心进行说明，对相同部分或相当部分简化或省略说明。图8是从斜上方观察实施方式2的照明装置1B的立体图。图9是从与基座2垂直的方向观察实施方式2的照明装置1B的俯视图。此外，在图9中，为了易于观察，表示在中途切断主体支承件9的臂部9b并除去了固定部9a的状态。另外，在图9中，为了易于理解电源框体7d的位置，用粗虚线表示电源框体7d的外缘。Hereinafter, Embodiment 2 will be described with reference to FIG. 8 and FIG. 9 , focusing on the differences from Embodiment 1 described above, and the same or corresponding parts will be simplified or omitted. FIG. 8 is a perspective view of the lighting device 1B according to Embodiment 2 as viewed obliquely from above. FIG. 9 is a plan view of the lighting device 1B according to Embodiment 2 viewed from a direction perpendicular to the base 2 . In addition, in FIG. 9, the arm part 9b of the main body support 9 is cut|disconnected halfway, and the state which removed the fixing|fixed part 9a is shown for easy observation. In addition, in FIG. 9, in order to understand the position of the power supply housing 7d easily, the outer edge of the power supply housing 7d is shown by a thick broken line.

如图8所示，实施方式2的照明装置1B与实施方式1的照明装置1A相比，电源装置7、电源支承件8以及风扇支承件12的配置不同。照明装置1B的电源装置7、电源支承件8以及风扇支承件12与照明装置1A相比，位于以基座中心线BC为中心旋转移动了90度的位置。As shown in FIG. 8 , the lighting device 1B of the second embodiment is different from the lighting device 1A of the first embodiment in the arrangement of the power supply device 7 , the power supply support 8 , and the fan support 12 . The power supply device 7 , the power supply support 8 , and the fan support 12 of the lighting device 1B are located at positions that are rotationally shifted by 90 degrees about the base center line BC as compared with the lighting device 1A.

如图9所示，在从与基座2垂直的方向观察时，如下所述。主体支承件9的旋转轴RA通过基座2的中心。电源框体7d的中心位于旋转轴RA上。电源框体7d的中心与旋转轴RA的距离实质上为零。基座2的中心与电源框体7d的中心之间的、与旋转轴RA平行的方向上的距离等于基座中心线BC与电源中心线PC的距离。As shown in FIG. 9 , when viewed from a direction perpendicular to the base 2 , it is as follows. The rotation axis RA of the main body support 9 passes through the center of the base 2 . The center of the power supply housing 7d is positioned on the rotation axis RA. The distance between the center of the power supply housing 7d and the rotation axis RA is substantially zero. The distance between the center of the base 2 and the center of the power supply housing 7d in the direction parallel to the rotation axis RA is equal to the distance between the base center line BC and the power supply center line PC.

由于电源中心线PC相对于基座中心线BC而位置偏移，因此照明装置1B的重量平衡偏向电源装置7侧。在照明装置1B通过主体支承件9安装于建筑物的状态下，照明装置1B的主体部以不相对于主体支承件9旋转的方式通过螺栓10固定。然而，若万一螺栓10松动，则有可能照明装置1B的主体部以旋转轴RA为中心旋转，照明装置1B的主体部倾斜。Since the power supply center line PC is displaced with respect to the base center line BC, the weight balance of the lighting device 1B is shifted toward the power supply device 7 side. In a state where the lighting device 1B is attached to the building via the body support 9 , the body portion of the lighting device 1B is fixed with the bolts 10 so as not to rotate relative to the body support 9 . However, if the bolt 10 is loosened by any chance, the main body of the lighting device 1B may be rotated around the rotation axis RA, and the main body of the lighting device 1B may be inclined.

电源框体7d的中心的位置可以认为与电源装置7的重心的位置大致相等。因此，电源装置7的重量能够视为作用于电源框体7d的中心。根据本实施方式，在从与基座2垂直的方向观察时，电源框体7d的中心位于旋转轴RA上，从而能够得到以下的效果。电源装置7的重量不易产生绕旋转轴RA的旋转力矩。因此，即使是万一螺栓10松动时，照明装置1B的主体部也不会以旋转轴RA为中心旋转，能够可靠地防止照明装置1B的主体部倾斜。The position of the center of the power supply housing 7d can be considered to be approximately equal to the position of the center of gravity of the power supply device 7 . Therefore, the weight of the power supply device 7 can be regarded as acting on the center of the power supply housing 7d. According to the present embodiment, when the center of the power supply housing 7d is positioned on the rotation axis RA when viewed from the direction perpendicular to the base 2, the following effects can be obtained. The weight of the power supply device 7 does not easily generate a rotational moment about the rotation axis RA. Therefore, even if the bolt 10 is loosened, the main body of the lighting device 1B does not rotate around the rotation axis RA, and the main body of the lighting device 1B can be reliably prevented from tilting.

作为变形例，若在从与基座2垂直的方向观察时，基座2的中心与电源框体7d的中心之间的、与旋转轴RA平行的方向上的距离比电源框体7d的中心与旋转轴RA之间的距离长，则能够得到与上述效果类似的效果。As a modification example, when viewed from a direction perpendicular to the base 2, the distance between the center of the base 2 and the center of the power supply housing 7d in a direction parallel to the rotation axis RA is greater than the distance between the center of the power supply housing 7d and the center of the power supply housing 7d. When the distance from the rotation axis RA is long, an effect similar to the above-mentioned effect can be obtained.

如图9所示，在从与基座2垂直的方向观察时，整个电源框体7d位于基座2的外缘的内侧。由此，能够得到以下的效果。由于能够削减照明装置1B的实质的占有空间，因此能够节省空间地配置照明装置1B。由于能够防止照明装置1B的重量平衡的恶化，因此能够减小地震时的照明装置1B的振幅，能够进一步提高抗震性。这样的结构及效果在实施方式1以及后述的实施方式3中也共通。As shown in FIG. 9 , when viewed from a direction perpendicular to the base 2 , the entire power supply housing 7 d is positioned inside the outer edge of the base 2 . Thereby, the following effects can be obtained. Since the substantial occupied space of the lighting device 1B can be reduced, the lighting device 1B can be arranged in a space-saving manner. Since the deterioration of the weight balance of the lighting device 1B can be prevented, the amplitude of the lighting device 1B at the time of an earthquake can be reduced, and the earthquake resistance can be further improved. Such a configuration and effects are also common to Embodiment 1 and Embodiment 3 to be described later.

在从与基座2垂直的方向观察时，电源框体7d具有以与连结基座2的中心和电源框体7d的中心的方向垂直的方向为长度方向的形状。由此，能够得到以下的效果。能够防止电源框体7d覆盖在基座2的中央区域的上方，并且能够增大电源框体7d的容积。能够更可靠地防止电源框体7d妨碍从冷却风扇6向基座2及散热片4的气流。这样的结构及效果在实施方式1中也共通。When viewed from a direction perpendicular to the base 2 , the power supply housing 7d has a shape whose longitudinal direction is a direction perpendicular to the direction connecting the center of the base 2 and the center of the power supply housing 7d. Thereby, the following effects can be obtained. The power supply housing 7d can be prevented from being covered above the central region of the base 2, and the volume of the power supply housing 7d can be increased. It is possible to more reliably prevent the power supply housing 7d from obstructing the airflow from the cooling fan 6 to the base 2 and the heat sink 4 . Such a configuration and effects are also common to the first embodiment.

从与基座2垂直的方向观察时的冷却风扇6的占有区域被分为第一区域6a及第二区域6b。第一区域6a是从与基座2垂直的方向观察时与电源框体7d重叠的区域。在图9中，为了便于理解，对第一区域6a标注了阴影线。第二区域6b是从与基座2垂直的方向观察时不与电源框体7d重叠的区域。在图9中，第二区域6b相当于冷却风扇6的占有区域中的未标注阴影线的区域。第二区域6b的面积大于第一区域6a的面积。根据这样的结构，能够得到以下的效果。第一区域6a的比例越大，吹到电源框体7d的气流越增加，吹到基座2及散热片4的气流越减少。相反地，第二区域6b的比例越大，吹到基座2及散热片4的气流越增加，吹到电源框体7d的气流越减少。通过使第二区域6b的面积大于第一区域6a的面积，能够充分地增多吹到基座2及散热片4的气流。另外，由于存在冷却风扇6与电源框体7d重叠的第一区域6a，从而能够使气流也可靠地吹到电源框体7d。以上那样的结构及效果在实施方式1中也共通。The area occupied by the cooling fan 6 when viewed from the direction perpendicular to the base 2 is divided into a first area 6a and a second area 6b. The first area 6a is an area that overlaps with the power supply housing 7d when viewed from the direction perpendicular to the base 2 . In FIG. 9, hatching is attached|subjected to the 1st area|region 6a for easy understanding. The second area 6b is an area that does not overlap with the power supply housing 7d when viewed from the direction perpendicular to the base 2 . In FIG. 9 , the second region 6 b corresponds to an unhatched region in the occupied region of the cooling fan 6 . The area of the second region 6b is larger than that of the first region 6a. According to such a configuration, the following effects can be obtained. The larger the ratio of the first area 6a, the more the airflow to the power supply housing 7d increases, and the more the airflow to the base 2 and the heat sink 4 decreases. Conversely, as the ratio of the second area 6b increases, the airflow to the base 2 and the heat sink 4 increases, and the airflow to the power supply housing 7d decreases. By making the area of the second region 6b larger than the area of the first region 6a, the airflow to the base 2 and the heat sink 4 can be sufficiently increased. In addition, since the first region 6a in which the cooling fan 6 overlaps with the power supply housing 7d exists, the airflow can also be surely blown to the power supply housing 7d. The above-mentioned configuration and effects are also common to the first embodiment.

如图12所示，在从与电源支承件20的梁部20b的长度方向垂直的方向观察时，如下所述。电源框体7q具有比梁部20b的边缘20c向外侧突出的突出部7r。电源框体7q具有隔着梁部20b相互位于相反侧的两个突出部7r。电源框体7q具有宽度L1。宽度L1是与梁部20b的长度方向垂直且与基座2平行的方向上的电源框体7q的尺寸。梁部20b具有宽度L2。宽度L2是与梁部20b的长度方向垂直且与基座2平行的方向上的梁部20b的尺寸。电源框体7q的宽度L1大于梁部20b的宽度L2。As shown in FIG. 12 , when viewed from a direction perpendicular to the longitudinal direction of the beam portion 20 b of the power source support 20 , the following is the case. The power supply housing 7q has a protruding portion 7r that protrudes outward from the edge 20c of the beam portion 20b. The power supply housing 7q has two protruding portions 7r located on opposite sides of each other with the beam portion 20b interposed therebetween. The power supply housing 7q has a width L1. The width L1 is the dimension of the power supply housing 7q in the direction perpendicular to the longitudinal direction of the beam portion 20b and parallel to the base 2 . The beam portion 20b has a width L2. The width L2 is the dimension of the beam portion 20b in the direction perpendicular to the longitudinal direction of the beam portion 20b and parallel to the base 2 . The width L1 of the power supply housing 7q is larger than the width L2 of the beam portion 20b.

电源框体7q具有空气入口7s及空气出口7t。空气入口7s及空气出口7t使电源框体7q的内部与外部连通。空气入口7s及空气出口7t是设置于形成电源框体7q的壁上的开口。空气入口7s及空气出口7t形成于电源框体7q的突出部7r。电源框体7q具有形成于电源框体7q的上表面的空气入口7s和形成于电源框体7q的侧面的空气入口7s。空气出口7t形成于电源框体7q的底面中的未被梁部20b覆盖的部分。在从与基座2垂直的方向观察时，形成于电源框体7q的上表面的空气入口7s的位置至少部分地与形成于电源框体7q的底面的空气出口7t的位置重叠。The power supply housing 7q has an air inlet 7s and an air outlet 7t. The air inlet 7s and the air outlet 7t communicate the inside and the outside of the power supply housing 7q. The air inlet 7s and the air outlet 7t are openings provided in the wall forming the power supply housing 7q. The air inlet 7s and the air outlet 7t are formed in the protruding portion 7r of the power supply housing 7q. The power supply housing 7q has an air inlet 7s formed on the upper surface of the power supply housing 7q and an air inlet 7s formed on the side surface of the power supply housing 7q. The air outlet 7t is formed in a portion of the bottom surface of the power supply housing 7q that is not covered by the beam portion 20b. The position of the air inlet 7s formed on the upper surface of the power supply housing 7q at least partially overlaps the position of the air outlet 7t formed on the bottom surface of the power supply housing 7q when viewed from the direction perpendicular to the base 2 .

在电源框体7q的内部配置有具有电气元件7j、7n的电子电路基板7c和散热器7u。散热器7u具备经由导热性材料7k与电气元件7j接触的板状的基座部、以及从该基座部向外侧突出的多个散热片。作为变形例，电气元件7j也可以与散热器7u的基座部直接接触。Inside the power supply housing 7q, an electronic circuit board 7c having electrical components 7j and 7n and a heat sink 7u are arranged. The heat sink 7u includes a plate-shaped base portion in contact with the electrical element 7j via the thermally conductive material 7k, and a plurality of fins protruding outward from the base portion. As a modified example, the electrical component 7j may be in direct contact with the base portion of the heat sink 7u.

当冷却风扇6运转时，如下所述。冷却风扇6产生的气流由图11中的带有箭头的曲线示意性地表示。通过从冷却风扇6向下吹出的气流，将基座2及散热片4冷却。通过冷却风扇6从上方吸入空气，空气通过空气入口7s及空气出口7t而在电源框体7q的内部流动。空气从空气入口7s流入到电源框体7q内。在电源框体7q的内部流动的空气从空气出口7t向电源框体7q外排出。从空气出口7t排出的空气被吸入冷却风扇6。When the cooling fan 6 operates, it is as follows. The air flow generated by the cooling fan 6 is schematically represented by a curve with arrows in FIG. 11 . The base 2 and the heat sink 4 are cooled by the airflow blown downward from the cooling fan 6 . Air is sucked in from above by the cooling fan 6, and the air flows inside the power supply housing 7q through the air inlet 7s and the air outlet 7t. Air flows into the power supply housing 7q from the air inlet 7s. The air flowing inside the power supply housing 7q is discharged from the air outlet 7t to the outside of the power supply housing 7q. The air discharged from the air outlet 7t is sucked into the cooling fan 6 .

根据本实施方式，能够得到以下的效果。通过使空气在电源框体7q的内部流动，能够高效地冷却位于电源框体7q的内部的电子电路基板7c的电气元件7j、7n。从电源框体7q的空气出口7t排出的空气能够流入冷却风扇6，因此能够减轻由冷却风扇6产生的气流的通气阻力。因此，向基座2及散热片4的风量变多，能够高效地冷却基座2及散热片4。作为比较例，若假设电源框体7q不具有空气入口7s及空气出口7t，则冷却风扇6的吸入口被电源框体7q的底面覆盖，从而由冷却风扇6产生的气流的通气阻力容易变大。According to the present embodiment, the following effects can be obtained. By allowing air to flow inside the power supply housing 7q, it is possible to efficiently cool the electrical components 7j and 7n of the electronic circuit board 7c located inside the power supply housing 7q. Since the air discharged from the air outlet 7t of the power supply housing 7q can flow into the cooling fan 6, the ventilation resistance of the airflow generated by the cooling fan 6 can be reduced. Therefore, the air volume to the susceptor 2 and the fins 4 increases, and the susceptor 2 and the fins 4 can be efficiently cooled. As a comparative example, if the power supply housing 7q does not have the air inlet 7s and the air outlet 7t, the suction port of the cooling fan 6 is covered by the bottom surface of the power supply housing 7q, and the ventilation resistance of the airflow generated by the cooling fan 6 tends to increase. .

在本实施方式中，在从与基座2垂直的方向观察时，空气出口7t的至少一部分位于与冷却风扇6重叠的位置。由此，能够得到以下的效果。从电源框体7q的空气出口7t排出的空气能够更顺畅地流入冷却风扇6。结果，在电源框体7q的内部通过的空气的流量变多。另外，能够进一步减轻由冷却风扇6产生的气流的通气阻力。In the present embodiment, at least a part of the air outlet 7t is located at a position overlapping the cooling fan 6 when viewed from the direction perpendicular to the base 2 . Thereby, the following effects can be obtained. The air discharged from the air outlet 7t of the power supply housing 7q can flow into the cooling fan 6 more smoothly. As a result, the flow rate of the air passing through the inside of the power supply housing 7q increases. In addition, the ventilation resistance of the airflow generated by the cooling fan 6 can be further reduced.

如图11所示，在本实施方式中，从与基座2平行的方向观察，在冷却风扇6与电源框体7q之间形成有空气能够通过的空间。来自该空间的空气不通过电源框体7q的内部而被吸入冷却风扇6。通过设置该空间，能够进一步减轻由冷却风扇6产生的气流的通气阻力，能够进一步增多冷却风扇6的风量。As shown in FIG. 11 , in the present embodiment, a space through which air can pass is formed between the cooling fan 6 and the power supply housing 7q when viewed from a direction parallel to the base 2 . The air from this space is sucked into the cooling fan 6 without passing through the inside of the power supply housing 7q. By providing this space, the ventilation resistance of the airflow generated by the cooling fan 6 can be further reduced, and the air volume of the cooling fan 6 can be further increased.

如图10所示，空气入口7s及空气出口7t分别具有沿着梁部20b的长度方向延伸的细长的形状。由此，能够得到以下的效果。能够可靠地防止大的异物从空气入口7s及空气出口7t进入到电源框体7q的内部，并且能够进一步增多在电源框体7q的内部通过的空气的流量。As shown in FIG. 10 , the air inlet 7s and the air outlet 7t each have an elongated shape extending along the longitudinal direction of the beam portion 20b. Thereby, the following effects can be obtained. It is possible to reliably prevent large foreign matter from entering the inside of the power supply housing 7q from the air inlet 7s and the air outlet 7t, and to further increase the flow rate of air passing through the power supply housing 7q.

根据本实施方式，由于电源装置7C具备散热器7u，从而能够进一步高效地冷却电气元件7j。从空气入口7s流入到电源框体7q内的空气沿着散热器7u的表面流动后，从空气出口7t向电源框体7q外排出。According to the present embodiment, since the power supply device 7C includes the heat sink 7u, it is possible to further efficiently cool the electrical components 7j. The air flowing into the power supply housing 7q from the air inlet 7s flows along the surface of the heat sink 7u, and is discharged to the outside of the power supply housing 7q from the air outlet 7t.
