  As shown in FIGS. 1 to 4, the lighting device 10 includes a main body 20, a first light emitting unit 30, a mounting plate 40, a translucent cover 50, a storage battery 60, a control unit 70, and a terminal block 80. And comprising.

  The illumination device 10 is a disaster prevention (emergency) illumination device used in a semi-outdoor space such as a common part of an apartment. Specifically, the illuminating device 10 is attached to a construction surface such as a ceiling or a bracket light as a ceiling light. In the present embodiment, the planar view shape of the illumination device 10 is a circle.

  The main body 20 is a member attached to a construction surface of a structure such as a ceiling or a wall surface, in other words, an attachment base. The main body 20 is formed by, for example, aluminum die casting or the like, but may be formed by other metal or resin. The main body 20 includes a flat plate-like base portion 21 having a circular shape in plan view, and a side wall portion 22 erected on the lower side in the vicinity of the periphery of the base portion 21.

  The base portion 21 is provided with an attachment structure (opening) for attaching the main body 20 to a structure. The base portion 21 has a flat plate shape, and the surface opposite to the surface on which the constituent members of the lighting device 10 such as the storage battery 60 described later are placed is attached to the construction surface of the structure. In addition, the construction surface of the structure and the surface on which the constituent members of the lighting device 10 such as the storage battery 60 are placed are substantially parallel. Moreover, in the following embodiment, the main body 20 (illuminating device 10) is demonstrated as what is attached to a ceiling. Two leg portions 23 are attached to the base portion 21.

  The leg portion 23 is disposed in the vicinity of the periphery of the base portion 21, one end portion (lower end portion) is connected to the connection portion 41 included in the mounting plate 40, and the other end portion (upper end portion) is They are connected in a state of being erected in a direction perpendicular to the construction surface of the structure. In other words, the leg portion 23 is a member for attaching the attachment plate 40 to the main body 20. The two leg portions 23 are disposed to face the vicinity of the periphery of the base portion 21. As described above, the structure in which the mounting plate 40 is connected to the base portion 21 by the leg portion 23 causes heat generated by the first light emitting portion 30 to be transmitted in the order of the mounting plate 40, the leg portion 23, and the base portion 21. Therefore, an effect is obtained in which the heat generated by the first light emitting unit 30 is less likely to be transmitted to the base unit 21 than the structure in which the first light emitting unit 30 is directly mounted on the base unit 21. The leg portion 23 is a plate material bent into a U-shape (U-shape, bracket shape). The leg portion 23 includes a leaf spring 24 and a support plate 25.

  The leaf spring 24 is an elastic body having a restoring force (spring restoring force) for holding the mounting plate 40 so as to be detachable and returning to its original shape when deformed. Specifically, the engaging portion 24 a that is a convex protrusion formed on the leaf spring 24 engages with the engaged portion 41 a that is an opening (through hole) formed in the connection portion 41 of the mounting plate 40. As a result, the mounting plate 40 is held by the leaf spring 24. The leaf spring 24 is formed of a metal material such as a stainless steel material, for example.

  The support plate 25 is a plate material that supports the plate spring 24 and is formed of a metal material having higher rigidity than the plate spring 24. For example, the support plate 25 is made of a metal material having a higher elastic modulus than that of the plate spring 24, and thus has high rigidity. As one specific example, the support plate 25 is formed of a galvanized steel plate. The support plate 25 only needs to be more rigid than the plate spring 24, and the same material as the plate spring 24 may be used. In that case, what is necessary is just to adjust the shape, size, etc. of the leaf | plate spring 24 and / or the support plate 25 suitably.

  One end of the support plate 25 is bent at a right angle toward the inside of the lighting device 10. The mounting plate 40 is placed on the restricting portion 25b, which is a portion that is substantially horizontal when one end of the support plate 25 is bent. That is, the restricting portion 25b is a portion formed by bending one end of the leg portion 23 (specifically, the support plate 25) of the lighting device 10. When the leg portion 23 has the restricting portion 25b, the operator can easily recognize the position where the attachment plate 40 is installed when attaching the attachment plate 40 to the leg portion 23. Moreover, also when the illuminating device 10 is attached to the wall or ceiling of a structure, the movement of the attachment board 40 is controlled by the control part 25b. Specifically, the movement of the attachment plate 40 in the direction perpendicular to the construction surface of the structure and the direction in which the attachment plate 40 moves away from the main body 20 is restricted by the restriction portion 25b. Therefore, in a state where the attachment plate 40 is attached to the main body 20, the attachment plate 40 is supported by the restricting portion 25b. In the present embodiment, in the state where the mounting plate 40 is mounted on the main body 20, the mounting plate 40 is placed on the restricting portion 25b. The mounting plate 40 placed on the restricting portion 25 b is held by the main body 20 by the leaf spring 24. The other end of the support plate 25 is bent at a right angle toward the inside of the lighting device 10 and is screwed to the base portion 21.

  The support plate 25 is separate from the main body 20, but may be formed integrally with the main body 20. In this case, the support plate 25 is formed by aluminum die casting as a part of the main body 20.

  A storage battery 60, a control unit 70, and a terminal block 80 are placed on the base portion 21 of the main body 20.

  The storage battery 60 is a power source that supplies power to the first light emitting unit 30. The storage battery 60 is used as an emergency power source, for example, when the supply of AC power from the outside is stopped. The storage battery 60 is, for example, a nickel metal hydride battery. The storage battery 60 may be a battery that can be charged and discharged, and may be a lithium ion battery or a lead storage battery. The storage battery 60 is covered from below by a storage battery cover 61. The storage battery cover 61 is formed by aluminum die casting, for example, but may be formed by resin.

  The control unit 70 is a power supply circuit unit including a power supply circuit that converts AC power supplied from the outside of the lighting device 10 into DC power and supplies the DC power to the first light emitting unit 30. Details of the control unit 70 will be described later.

  The terminal block 80 is a terminal unit in which one or a plurality of terminals into which electric wires are inserted in order to electrically connect the external AC power supply and the control unit 70 are provided. AC power is supplied from an external AC power source to the control unit 70 via an electric wire inserted into the terminal block 80.

  The 1st light emission part 30 functions as a light source for illumination of the illuminating device 10 which radiate | emits illumination light. Specifically, the first light emitting unit 30 includes a COB (Chip On Board) type light emitting module 31 in which an LED chip mounted on a substrate is sealed with a translucent resin containing a phosphor. The first light emitting unit 30 has a circular light emitting region. In the present embodiment, the first light emitting unit 30 further includes a lens 33 for controlling light distribution, and a holder 32 for screwing the first light emitting unit 30 to the mounting plate 40. For example, the first light emitting unit 30 emits illumination light mainly including white light downward. That is, the first light emitting unit 30 emits white light toward the translucent cover 50.

  In addition, the first light emitting unit 30 is disposed between the light transmitting member 51 provided in the light transmitting cover 50 and the mounting plate 40. Further, when viewed in a plan view, the first light emitting unit 30 is disposed on the mounting surface 42 a located substantially at the center of the lower surface of the mounting plate 40. The first light emitting unit 30 is mounted on the mounting surface 42a of the mounting plate 40 and is screwed to the mounting surface 42a. In addition, although not shown in figure, the 1st light emission part 30 is electrically connected with the storage battery 60 and the control unit 70 with a lead wire.

May be. In the illumination device 10 according to the embodiment, the illumination device 10 includes a storage battery 60. For example, a disaster prevention (emergency) lighting device with a built-in storage battery needs to periodically check the state of the storage battery. At this time, if it is confirmed that the storage battery does not satisfy the capacity required for the storage battery, the storage battery needs to be replaced. Therefore, in the illuminating device 10, the attachment plate 40 and the translucent cover 50 are detachably attached to the main body 20 in order to facilitate replacement of the storage battery 60 attached to the main body 20.

  The mounting plate 40 is a mounting member that holds the first light emitting unit 30 and is detachably held by the main body 20. Specifically, the attachment plate 40 is detachably attached to one end portion of the leg portion 23 by being slid and inserted in a direction parallel to the construction surface. The attachment plate 40 is attached to the main body 20 so as to cover the storage battery 60, the control unit 70 and the terminal block 80 placed on the base portion 21. In other words, the storage battery 60, the control unit 70 and the terminal block 80 are covered with the mounting plate 40 and placed on the main body 20. Further, the mounting plate 40 includes the main body 20 (specifically, the base portion 21) and the transparent cover 50 (specifically, the transparent cover 50) in the optical axis direction (Y-axis direction) of the first light emitting unit 30. It arrange | positions between the light transmissive members 51). As shown in FIG. 4, gaps (air layers) are arranged between the attachment plate 40 and the base portion 21 and between the attachment plate 40 and the light transmission member 51. That is, the mounting plate 40 does not directly contact any member of the main body 20 and the light transmission member 51. As described above, according to the structure in which the first light emitting unit 30 is mounted on the mounting surface 42 a of the mounting plate 40, the first light emitting unit is more effective than the structure in which the first light emitting unit 30 is mounted on the base portion 21. The effect that the heat generated by 30 is difficult to be transmitted to the base portion 21 is obtained.

  The mounting plate 40 has a substantially funnel shape with a diameter decreasing toward the upper side (base portion 21 side). In other words, the mounting plate 40 has a funnel shape in which the opening area increases as the distance from the first light emitting unit 30 increases. The mounting plate 40 is made of, for example, aluminum, but may be made of other metals or resins.

  As shown in FIG. 3, the mounting plate 40 includes a mounting surface 42 a and a reflecting surface 42 b on the main surface 42 (the lower surface side of the mounting plate 40) of the mounting plate 40.

  The mounting surface 42a is located at a substantially central portion of the mounting plate 40 and is a part of the main surface 42 on which the first light emitting unit 30 is mounted. The planar view shape of the mounting surface 42a is not particularly limited, but is circular in the present embodiment. The first light emitting unit 30 is positioned between the light transmitting member 51 and the mounting plate 40 by being mounted on the mounting surface 42a.

It mounts from the upper direction of the formed control part 25b. The mounted mounting plate 40 has an engaging portion 24a formed by projecting a part of a leaf spring 24 of the leg portion 23 to an engaged portion 41a penetrating the mounting plate 40 formed in the connecting portion 41. Is held by engagement.

  The translucent cover 50 is a cover member that is part of the outer casing of the lighting device 10 and that is detachable from the main body 20. The light transmissive cover 50 includes a light transmissive member 51 and a cylindrical body 52.

  The light transmitting member 51 is a substantially circular dome-shaped optical member (glove) protruding downward. The light transmission member 51 is, for example, white or milky white and has light diffusibility (light scattering) and translucency.

  The light transmission member 51 is attached to the cylinder 52 so as to close the lower opening of the cylinder 52. Specifically, the light transmissive member 51 has an edge of the light transmissive member 51 protruding in a bowl shape toward the outside, and an upper surface of a lower surface of a cover holder (not shown) and a portion of the cylindrical body 52 protruding in a bowl shape.

By doing so, it is possible to prevent the lighting device 10 from igniting due to the spread of fire when a fire occurs.

  As shown in FIG. 5, the attachment plate 40 is attached to the main body 20 (specifically, the leg portion 23) by slidingly inserting the attachment plate 40 from the side of the main body 20. Specifically, the direction (attachment direction) in which the attachment plate 40 is slid and inserted into the main body 20 is a direction parallel to the construction surface of the structure. In the present embodiment, the construction surface of the structure is an XZ plane. In FIG. 5, the attachment plate 40 is attached to the leg portion 23 by being slid in the positive direction of the X axis.

  Note that the storage battery 60, the control unit 70, and the terminal block 80 placed on the base portion 21 are preferably placed at positions that do not come into contact with the mounting plate 40 when the mounting plate 40 is slid into the main body 20. Specifically, since the mounting plate 40 is substantially funnel-shaped as described above, the storage battery 60, the control unit 70, and the upper surface of the reflection surface 42b or the peripheral edge portion 44 of the mounting plate 40 are not the upper portion of the mounting surface 42a. The terminal block 80 may be placed. Moreover, the storage battery 60, the control unit 70, and the terminal block 80 are not on the X axis negative direction side of the main body 20 on the side where the mounting plate 40 is slid and inserted, but on the X axis positive direction side of the main body 20 on the opposite side. It should be arranged. By doing so, the attachment plate 40 is attached to the leg portion 23 without contacting the storage battery 60, the control unit 70 and the terminal block 80. That is, the illumination device 10 is reduced in size.

  As shown in FIG. 5, the attachment plate 40 has a pair of connection portions 41. In addition, a pair of leg portions 23 is erected on the main body 20. Here, the pair of connection portions 41 and the pair of leg portions 23 are arranged at corresponding positions. Specifically, when the mounting plate 40 is slid and inserted into the leg portion 23, the mounting plate 40 is slid in the direction of the one-dot chain line in FIG. 5, and one connection portion 41 is connected to one leg portion 23. The other connection portion 41 is disposed on the other leg portion 23.

  Next, details of the control unit 70 will be described with reference to FIGS.

FIG. 7 is an internal bottom view of the lighting device 10 according to the embodiment when the translucent cover 50 and the mounting plate 40 are removed. FIG. 8 is a cross-sectional view of the lighting device 10 taken along the line VIII-VIII in FIG. FIG. 9 is a partially enlarged view showing a region surrounded by a broken line IX in FIG. FIG. 8 is a cross-sectional view taken along a position corresponding to the line VIII-VIII in FIG. 6 in a state in which the illumination device 10 includes the translucent cover 50, unlike FIG.

  The control unit 70 is a control mechanism that controls a light source and the like included in the lighting device 10. For example, the control unit 70 is screwed to the base portion 21 while being placed on the lower surface of the base portion 21. As shown in FIGS. 6 to 9, the control unit 70 includes a second light emitting unit 71, an optical unit 72, an inspection switch 73, and a control unit 74.

  The second light emitting unit 71 is a light source whose lighting state is switched according to the state of the storage battery 60. Specifically, the second light emitting unit 71 is a monitor lamp that presents to the operator of the lighting device 10 whether or not the storage battery 60 is functioning normally by lighting (continuous lighting) or blinking. The 2nd light emission part 71 is comprised, for example by bullet-type LED. Further, as described above, the lighting device 10 includes the first light emitting unit 30 that functions as an illumination light source of the lighting device 10, separately from the second light emitting unit 71. Even when the first light emitting unit 30 is turned on, the colors of the light emitted by the first light emitting unit 30 and the second light emitting unit 71 are different in order to make it easier to check whether the second light emitting unit 71 emits light. Good. For example, the first light emitting unit 30 may emit white light and the second light emitting unit 71 may emit green light. The second light emitting unit 71 is disposed on the opposite side of the main surface 42 of the mounting plate 40 corresponding to the position where the opening 43 that is a through hole formed in the vicinity of the peripheral edge (peripheral portion 44) of the mounting plate 40 is formed. Is done.

  As shown in FIG. 8, the peripheral edge 44 of the mounting plate 40 is formed by continuously bending from the portion of the mounting plate 40 where the reflecting surface 42 b that is a tapered surface is formed. Specifically, the peripheral portion 44 is formed in the vicinity of the peripheral portion of the mounting plate 40 and bent in a direction substantially perpendicular to the optical axis (Y-axis direction) of light emitted from the first light emitting unit 30. In addition, an opening 43 that is a through-hole penetrating from the main surface 42 side of the mounting plate 40 to the surface opposite to the main surface 42 is formed in the peripheral portion 44. Above the opening 43, a second light emitting unit 71 of the control unit 70 is disposed. Here, the 2nd light emission part 71 is arrange | positioned at the control unit 70 so that light may be radiate | emitted toward the opening part 43 side. Therefore, the light emitted from the second light emitting unit 71 passes through the light transmitting member 51 and is emitted to the outside of the lighting device 10 without removing the mounting plate 40 from the main body 20.

  The light transmissive member 51 has light diffusibility (light scattering) as described above. Here, when the light transmissive member 51 is viewed in plan, the peripheral portion of the light transmissive member 51 may be less diffused than the central portion of the light transmissive member 51. Specifically, as shown in FIG. 8, the light diffusing degree of the light transmissive region LA through which the outgoing light L emitted from the second light emitting unit 71 of the light transmissive member 51 passes is light transmissive other than the light transmissive region LA. The degree of light diffusion in the region on the center side of the member 51 may be less.

  The light transmission member 51 may have light diffusibility (light scattering) in order to diffuse (scatter) the light emitted from the first light emitting unit 30. However, since the emitted light L of the second light emitting unit 71 only needs to be confirmed in the lighting state, it is better not to be diffused. Therefore, when the light transmissive member 51 is viewed in plan, the end portion of the light transmissive member 51 may be less diffused than the central portion of the light transmissive member 51.

  For example, since the light transmission member 51 has light diffusibility, a milky white light diffusion film including a light diffusion material or the like is formed on the inner surface of the light transmission member. In this case, the film thickness of the light diffusion film formed on the peripheral edge of the light transmitting member 51 is preferably thinner than the central portion of the light transmitting member 51. Alternatively, the light diffusion film may be formed only at the central portion of the light transmission member 51, and the light diffusion film may not be formed at the peripheral portion of the light transmission member 51.

  The optical unit 72 is an optical member having a function of controlling the light distribution of the emitted light L emitted from the second light emitting unit 71. As shown in FIG. 9, the optical unit 72 reflects a part of the emitted light L emitted from the second light emitting unit 71 toward the opening 43. Specifically, the optical unit 72 functions to suppress the spread of the emitted light L emitted from the second light emitting unit 71. The optical unit 72 is formed in a cylindrical shape so as to surround the periphery of the second light emitting unit 71 by, for example, a resin material. The resin material is, for example, a silicone resin to which a reflective (light reflective) material such as titanium oxide is added. Accordingly, the optical unit 72 also functions to reflect the emitted light L emitted from the second light emitting unit 71 toward the light transmitting member 51 side.

  The optical unit 72 may be, for example, a lens or the like, or a combination of the lens and the resin material described above in order to suppress the spread of the emitted light L.

  The inspection switch 73 is a switch that acquires an instruction from an operator who uses the lighting device 10. Specifically, when the inspection switch 73 acquires an instruction from the operator, the control unit 74 executes a process for confirming the state of the storage battery 60. The inspection switch 73 may be a button directly pressed by an operator, for example, but may be an optical sensor such as a PD (Photo Diode). That is, the inspection switch 73 may be an optical sensor that receives a signal such as an infrared ray emitted from a remote controller operated by an operator. In addition, as the inspection switch 73, the button type switch mentioned above and the optical sensor may be provided in the illuminating device 10. FIG.

  The control unit 74 is a processing unit that controls the lighting state of the second light emitting unit 71. The control unit 74 checks whether or not the storage battery 60 is functioning normally when the check switch 73 receives an instruction from the operator. In accordance with the inspection result, the control unit 74 causes the second light emitting unit 71 to emit light in a predetermined lighting state. Details of the processing procedure for confirming the state of the storage battery executed by the control unit 74 will be described later.

  The control unit 74 is realized by, for example, a memory in which a control program is stored, a CPU (Central Processing Unit) that executes the control program, and the like. Note that the control unit 74 does not have to be realized in software by a processor executing a program, and may be realized in hardware by a dedicated electronic circuit using a gate array or the like.

  Moreover, the control part 74 is provided with a power supply circuit as mentioned above. Specifically, the control unit 74 includes a power supply circuit formed by mounting circuit components on a substrate. The power supply circuit includes a rectifier circuit, an inverter circuit, and the like.

  The power supply circuit includes a charging circuit that charges the storage battery 60. The charging circuit converts AC power supplied from the outside of the lighting device 10 into DC power suitable for charging the storage battery 60 and charges the storage battery 60 with the DC power. In the present embodiment, in the lighting device 10, the storage battery 60 is trickle charged so that the lighting device 10 can be used even in an emergency such as a power failure.

  The power supply circuit also includes a detection circuit that detects a stop (power failure) of the supply of AC power from the outside, and a discharge circuit that discharges the storage battery 60. When a power failure is detected by the detection circuit, the discharge circuit discharges the storage battery 60. As a result, the storage battery 60 supplies DC power to the first light emitting unit 30. Thereby, the illuminating device 10 can continue light emission at the time of a power failure.

  Next, a processing procedure for checking the state of the storage battery 60 included in the lighting device 10 according to the embodiment will be described. FIG. 10 is a flowchart illustrating a processing procedure for checking the state of the storage battery 60 included in the lighting device 10 according to the embodiment. Specifically, in FIG. 10, when the inspection switch 73 receives an instruction from the operator, the control unit 74 checks whether the storage battery 60 is functioning normally, and the second is determined according to the inspection result. It is a flowchart which shows the process sequence for performing the control which lights the light emission part 71 in a predetermined | prescribed aspect.

  An operator who uses the lighting device 10 issues an instruction to the inspection switch 73 when checking whether or not the storage battery 60 is functioning normally. Specifically, when the inspection switch 73 is an optical sensor, the operator operates a predetermined remote controller to transmit an instruction to inspect the storage battery 60 to the inspection switch. The inspection switch 73 acquires the instruction (step S101).

  The control unit 74 checks the state of the storage battery 60 when the check switch 73 acquires the instruction. First, the control unit 74 checks (determines) whether the storage battery 60 and the first light emitting unit 30 are electrically connected (step S102). Specifically, the control unit 74 stops supplying the power supplied from the outside to the first light emitting unit 30 and supplies the power stored in the storage battery 60 to the first light emitting unit 30. Whether or not power can be supplied to the first light emitting unit 30 is confirmed. In other words, when the inspection switch 73 acquires an instruction from the operator, the control unit 74 causes the first light emitting unit 30 to emit light by discharging the storage battery 60 in the same manner as during a power failure. Here, when the control unit 74 determines that the storage battery 60 and the first light emitting unit 30 are not electrically connected (No in step S102), the control unit 74 blinks the second light emitting unit 71. Control is performed to emit light (step S106).

  Next, when it determines with the storage battery 60 and the 1st light emission part 30 being electrically connected (Yes in step S102), the control part 74 checks whether the storage battery 60 is charged (step). S103). When the lighting device 10 is used as, for example, an emergency lighting device and the storage battery 60 is used as an emergency power source, it is necessary to always keep it fully charged so that it can cope with any power failure. is there. In such a case, in step S103, it is confirmed whether or not the storage battery 60 is fully charged. Here, when it determines with the storage battery 60 not being charged (it is No at step S103), the control part 74 controls the 2nd light emission part 71 to blink and light-emit (step S106).

  Next, when it is determined that the storage battery 60 is charged (Yes in step S103), the control unit 74 checks whether or not the first light emitting unit 30 can be kept lit normally for a predetermined time by discharging the storage battery 60. (Step S104). Specifically, the control unit 74 includes a timer (clock) such as an RTC (Real Time Clock), and measures the lighting time of the first light emitting unit 30 due to the discharge of the storage battery 60 at the timer. Although predetermined time is not specifically limited, For example, 10 minutes may be sufficient, 30 minutes may be sufficient, and 1 hour may be sufficient. Here, the control unit 74 controls the second light emitting unit 71 to blink and emit light when the first light emitting unit 30 has not been normally lit for a predetermined time due to the discharge of the storage battery 60 (No in step S104). (Step S106). Moreover, the control part 74 performs control which lights the 2nd light emission part 71, when the 1st light emission part 30 is continued to light normally for predetermined time by discharge of the storage battery 60 (it is Yes at step S104) (step S105). ). Here, lighting indicates a state in which the second light emitting unit 71 is continuously emitting light.

  As described above, the lighting state of the second light emitting unit 71 is switched according to the state of the storage battery 60. Specifically, the control unit 74 switches the lighting state of the second light emitting unit 71 according to the state of the storage battery 60. Thereby, the operator of the illuminating device 10 can confirm whether the storage battery 60 is a normal state by confirming the lighting state of the 2nd light emission part 71. FIG.

  Note that the processing procedure illustrated in FIG. 10 is merely an example, and the order of the processing procedure may be changed. Further, when the control unit 74 determines No in step S102, step S103, and step S104, the second light emitting unit 71 is controlled to blink in step S106. However, it is necessary to make the same blinking state in each processing procedure. There is no. Specifically, the blinking state of the second light emitting unit 71 is determined by the processing procedure that has shifted from step S102 to step S106, the processing procedure that has shifted from step S102 to step S106, and the processing procedure that has shifted from step S102 to step S106. May be different. Here, the different blinking states are, for example, states in which the cycle of lighting and extinguishing, the length of lighting time, the length of lighting time, and the like are different in a state where the second light emitting unit 71 is blinking.

  Moreover, the control part 74 may perform control which lights the 2nd light emission part 71, when the inspection switch 73 acquires the instruction | indication from an operator in step S101. By doing so, it is possible to present to the operator that the lighting device 10 has acquired an instruction from the operator. In this case, when the control unit 74 determines No in step S102, step S103, and step S104, the second light emitting unit 71 may be controlled to switch the light emitting state from the lighting state to the blinking state.

  In step S106, the control unit 74 controls the second light emitting unit 71 to blink. However, it is only necessary to indicate to the operator that the storage battery 60 is abnormal. For example, the second light emitting unit 71 can emit light of a plurality of colors, and the emission color may be changed depending on whether the storage battery 60 is determined to be normal or abnormal.

  Moreover, although the control part 74 will check the state of the storage battery 60, when the inspection switch 73 acquires the instruction | indication from an operator, the conditions which start the said inspection are not limited. For example, the control unit 74 includes a timing unit and a memory, and a control program that periodically executes the steps shown in FIG. 10 is stored in advance in the memory, and the control program is periodically executed by the control unit 74. May be.

(Effects etc.)
As described above, the lighting device 10 includes the first light emitting unit 30 and the mounting plate 40 having the main surface 42 to which the first light emitting unit 30 is attached and having the opening 43 near the periphery. The lighting device 10 is disposed on the opposite side of the main surface 42 corresponding to the position where the opening 43 is formed, and the second light emitting unit 71 that emits light toward the opening 43 and the first light emitting unit 30. And a storage battery 60 for supplying electric power. The lighting state of the second light emitting unit 71 is switched according to the state of the storage battery 60.

  Thereby, the operator of the illuminating device 10 determines whether the storage battery 60 included in the illuminating device 10 functions normally even in an emergency, for example, without removing the translucent cover 50 included in the illuminating device 10. This can be confirmed by the lighting state of the light emitting unit 71. Therefore, according to the illumination device 10, the operator can easily check the state of the storage battery 60.

  Moreover, the illuminating device 10 checks the state of the storage battery 60 when the inspection switch 73 acquires an instruction from the operator and the inspection switch 73 acquires the instruction, and the second light emitting unit according to the state of the storage battery 60 And a control unit 74 that switches the lighting state of 71.

  Thereby, according to the instruction | indication from the operator of the illuminating device 10, the state of the storage battery 60 is confirmed. Therefore, the operator can check the state of the storage battery 60 included in the lighting device 10 at a desired timing.

  The inspection switch 73 may be an optical sensor.

  That is, the operator of the lighting device 10 can instruct the lighting device 10 to check the state of the storage battery 60 by operating a predetermined remote controller. Therefore, according to the illumination device 10, the operator can easily check the state of the storage battery 60.

  Moreover, the color of the light which the 1st light emission part 30 and the 2nd light emission part 71 emit may differ.

  Thereby, even in a state where the first light emitting unit 30 is lit, the operator can easily confirm whether or not the second light emitting unit 71 is lit.

  Moreover, the illuminating device 10 may further include a light transmissive member 51 having a light diffusibility that covers the main surface 42 side and transmits light from the first light emitting unit 30 and the second light emitting unit 71. Further, when viewed in a plan view, the peripheral portion of the light transmitting member 51 may have a smaller light diffusion degree than the central portion of the light transmitting member 51.

  Thereby, the emitted light L emitted from the second light emitting unit 71 is not easily diffused (scattered) by the light transmitting member 51. That is, the operator of the lighting device 10 can easily check whether the second light emitting unit 71 is lit even when the amount of the emitted light L is small.

  The illumination device 10 may further include an optical unit 72 that controls the light distribution of the light emitted from the second light emitting unit 71.

  Specifically, the optical unit 72 functions to suppress the spread of the emitted light L emitted from the second light emitting unit 71. Thereby, the operator of the illuminating device 10 can easily confirm whether or not the second light emitting unit 71 is lit.

  Further, as the optical unit 72, a resin material that reflects the emitted light L of the second light emitting unit 71 may be employed. Further, the resin material may be formed in a cylindrical shape so as to surround the second light emitting unit 71.

  Thereby, the optical part 72 becomes easy to guide the emitted light L to the light transmission member 51 side. Therefore, the loss of the emitted light L inside the lighting device 10 is suppressed.

  Further, the first light emitting unit 30 may be disposed at substantially the center of the mounting plate 40 in a plan view. The mounting plate 40 may have a funnel shape in which the opening area increases as the distance from the first light emitting unit 30 increases.

  Thereby, the light emitted from the first light emitting unit 30 reflected by the reflecting surface 42b is efficiently guided to the outside of the illumination device 10.

  Further, the vicinity of the periphery (peripheral portion 44) of the mounting plate 40 may be formed by bending in a direction substantially perpendicular to the optical axis of the light emitted from the first light emitting unit 30.

  Thereby, the light emitted from the first light emitting unit 30 is less likely to reach the peripheral portion 44 directly. That is, since the peripheral portion 44 does not reflect the light emitted from the first light emitting unit 30, the amount of light emitted from the first light emitting unit 30 on the light transmitting member 51 near the peripheral portion 44, that is, the outer peripheral side of the light transmitting member 51 is Less. Therefore, the operator of the illumination device 10 can easily confirm the emitted light L emitted to the outer peripheral side of the light transmission member 51.

  Further, the main surface 42 of the mounting plate 40 has a mounting surface 42a on which the first light emitting unit 30 is mounted and a reflection disposed around the mounting surface 42a that reflects light emitted from the first light emitting unit 30. And the surface 42b.

  Thereby, the light emitted from the first light emitting unit 30 is effectively guided from the inside of the lighting device 10 to the outside of the lighting device 10. Therefore, the light use efficiency of the illumination device 10 is improved.
