  As shown in FIGS. 1 to 6, the lighting device 10 includes an instrument body 11, a light emitting unit 30, a reflecting plate 40, a translucent cover 50, a storage battery 60, a lighting control device 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 lighting 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 “plan view” indicates a case where the main surface 12a provided on the instrument main body 11 or the mounting surface 41 provided on the reflection plate 40 is viewed from the normal direction.

  The instrument body 11 is a member attached to a construction surface of a construction material such as a ceiling or a wall surface, in other words, an attachment base. The instrument body 11 is formed by, for example, aluminum die casting or the like, but may be formed by other metals or resins. The instrument main body 11 is a bottomed cylindrical shape including a flat plate-like base portion 12 having a circular shape in plan view and a side wall portion 13 erected on the lower side in the vicinity of the periphery of the base portion 12.

  The base portion 12 is provided with an attachment structure (opening) for attaching the instrument body 11 to the construction material. The base portion 12 has a flat plate shape, and the surface (mounting surface 12b) side opposite to the surface (main surface 12a) on which the constituent members of the lighting device 10 such as the storage battery 60 described later are placed is the construction material construction. Mounted on the surface. In addition, when the illuminating device 10 is attached to the construction material, the construction surface of the construction material and the main surface 12a on which the constituent members of the illuminating device 10 such as the storage battery 60 are placed are substantially parallel.

  The base portion 12 is provided with two attachment portions 14.

  In the description of FIGS. 1 to 6, the instrument body 11 (lighting device 10) is described as being attached to the ceiling.

  The attachment portion 14 is a member that restricts the movement of the reflection plate 40 in a direction parallel to the main surface 12a and is detachably attached to the reflection plate 40, and stands in a direction perpendicular to the construction surface of the construction material. It is provided in the base part 12 in the installed state. That is, the attachment part 14 is a member for attaching the reflector 40 to the instrument main body 11 so that attachment or detachment is possible. In addition, the structure of the attaching part 14 is not limited. For example, the mounting portion 14 includes a screw 26 and a column portion 27 that supports the screw 26 and is erected on the base portion 12.

  As shown in FIG. 3, the reflector 40 has a pair of mounting holes 45. The instrument body 11 is provided with a pair of attachment portions 14. Further, the pair of attachment holes 45 and the pair of attachment portions 14 are arranged at corresponding positions.

  A storage battery 60, a lighting control device 70, and a terminal block 80 are placed on the base portion 12 of the instrument body 11.

  The storage battery 60 is a power source that supplies power to the 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 lighting control device 70 is a power supply circuit unit that converts AC power supplied from the outside of the lighting device 10 into DC power and supplies the DC power to the light emitting unit 30. Specifically, the lighting control device 70 includes a power supply circuit formed by mounting circuit components on a substrate and a resin cover. The power supply circuit includes a rectifier circuit, an inverter circuit, and the like. For example, the lighting control device 70 is screwed to the base portion 12 while being placed on the main surface 12a of the base portion 12.

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

  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, 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 light emitting unit 30. Thereby, the illuminating device 10 can continue light emission at the time of a power failure.

  The light emitting unit 30 functions as an illumination light source of the illumination device 10 that emits illumination light. Specifically, the light emitting unit 30 is a COB (Chip On Board) type light emitting module 31 in which an LED (Light Emitting Diode) chip mounted on a substrate is sealed with a translucent resin containing a phosphor. Is provided. The light emitting unit 30 has a circular light emitting region. In the present embodiment, the light emitting unit 30 further includes a lens for controlling light distribution, and includes a holder 32 for screwing the light emitting unit 30 to the reflection plate 40. For example, the light emitting unit 30 emits illumination light mainly including white light downward. That is, the light emitting unit 30 emits white light toward the translucent cover 50. In addition, between the light emission part 30 and the mounting surface 41, heat radiating members, such as the heat radiating sheet 33, may be arrange | positioned.

  In addition, the light emitting unit 30 is disposed between the light transmitting member 51 provided in the light transmitting cover 50 and the reflecting plate 40. Further, when viewed in a plan view, the light emitting unit 30 is disposed on the mounting surface 41 located at the center of the lower surface of the reflecting plate 40. The light emitting unit 30 is mounted on the mounting surface 41 of the reflecting plate 40 and is screwed to the mounting surface 41. In addition, although not shown in figure, the light emission part 30 is electrically connected with the storage battery 60 and the lighting control apparatus 70 with a lead wire.

  By the way, as described above, the fixture main body of the lighting device fixed to the construction material such as the wall and the ceiling, and the constituent members of the lighting device included in the lighting device can be attached and detached in order to replace the light source provided in the lighting device. May be installed. In the illumination device 10 according to the embodiment, the illumination device 10 includes a storage battery 60. Generally, 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 reflector 40 and the translucent cover 50 are detachably attached to the fixture body 11 in order to facilitate replacement of the storage battery 60 attached to the fixture body 11.

  The reflecting plate 40 is a plate that is provided with a mounting surface 41 on which the light emitting unit 30 is disposed and reflects light emitted from the light emitting unit 30. Further, the reflection plate 40 reflects light emitted from the light emitting unit 30 toward the light transmitting cover 50 (specifically, the light transmitting member 51). The reflector 40 is an attachment member for detachably attaching the light emitting unit 30 to the instrument body 11. Specifically, the reflector 40 is detachably attached to the instrument main body 11 (specifically, the attachment portion 14) by sliding in a direction parallel to the main surface 12a. Further, the reflection plate 40 is attached to the instrument body 11 so as to cover the storage battery 60, the lighting control device 70 and the terminal block 80 placed on the base portion 12. In other words, the storage battery 60, the lighting control device 70, and the terminal block 80 are covered with the reflecting plate 40 and placed on the instrument body 11. In addition, the reflecting plate 40 has the instrument main body 11 (specifically, the base portion 12) and the translucent cover 50 (specifically, translucent light) in the optical axis L direction (Y-axis direction shown in FIG. 6) of the light emitting unit 30. It arrange | positions between the light transmissive members 51) with which the cover 50 is provided. As shown in FIG. 6, gaps (air layers) are formed between the reflecting plate 40 and the base portion 12 and between the reflecting plate 40 and the light transmission member 51. That is, the reflecting plate 40 does not directly contact any member of the instrument main body 11 and the light transmission member 51. Thus, according to the structure in which the light emitting unit 30 is mounted on the mounting surface 41 of the reflecting plate 40, the heat generated by the light emitting unit 30 is based on the base compared to the structure in which the light emitting unit 30 is mounted on the base unit 12. An effect that is difficult to be transmitted to the portion 12 is obtained.

  Moreover, the reflecting plate 40 has a substantially funnel shape with a diameter reduced toward the upper side (base portion 12 side). In other words, the reflecting plate 40 has a funnel shape in which the opening area increases as the distance from the light emitting unit 30 increases. The reflecting plate 40 is formed of, for example, aluminum, but may be formed of other metals or resins.

  The storage battery 60, the lighting control device 70, and the terminal block 80 placed on the base portion 12 are placed at positions where they do not come into contact with the reflector 40 when the reflector 40 is slid and attached to the instrument body 11.

  As shown in FIG. 3, the reflection plate 40 includes a placement surface 41, an inclined portion 42, and a flat portion 43.

  The mounting surface 41 is a plane on which the light emitting unit 30 is mounted, which is positioned substantially at the center of the reflecting plate 40. The planar view shape of the mounting surface 41 is not particularly limited, but is circular in the present embodiment. The light emitting unit 30 is positioned between the light transmitting member 51 and the reflecting plate 40 by being mounted on the mounting surface 41.

  Further, a heat sink may be disposed on the surface of the reflecting plate 40 opposite to the mounting surface 41, that is, the surface facing away from the mounting surface 41. According to the heat sink, heat generated by the light emitting unit 30 during light emission can be released to the heat sink. The heat sink is formed by, for example, aluminum die casting, but may be formed by other metals.

  In addition, the reflecting plate 40 may include an inclined portion 42 that reflects the light emitted from the light emitting unit 30 toward the translucent cover 50. The inclined portion 42 is a portion formed continuously with the mounting surface 41 so as to surround the periphery of the mounting surface 41, and reflects a part of light emitted from the light emitting unit 30 toward the light transmitting member 51. The inclined portion 42 is a tapered portion that is partially curved in the radial direction.

  In addition, a flange-shaped flat portion 43 extending from the inclined portion 42 to the base portion 12 side is provided on the peripheral portion of the reflecting plate 40 with respect to the inclined portion 42. Specifically, a flat portion 43 that is inclined with respect to the inclined portion 42 and substantially parallel to the placement surface 41 is provided at the peripheral edge of the reflecting plate 40. In other words, in the vicinity of the periphery of the reflecting plate 40, a flat portion 43 formed by bending in a direction substantially perpendicular to the optical axis L direction of the light emitted from the light emitting portion 30 is provided. A mounting hole 45 is provided in the flat portion 43.

  A pair of mounting holes 45 are arranged on the periphery of the reflector 40 so as to face each other. The attachment hole 45 is a hole that is located corresponding to the attachment portion 14 and is formed so as to penetrate in the optical axis L direction. The reflector 40 is attached to the instrument body 11 by engaging the attachment hole 45 with the attachment portion 14. In addition, the number of the attachment holes 45 arrange | positioned at the flat part 43 of the reflecting plate 40 is not specifically limited. The number corresponding to the attachment part 14 provided in the instrument main body 11 is good to provide.

The frame body 52 constitutes an outer casing of the lighting device 10 together with the instrument main body 11 and the light transmission member 51. The frame body 52 corresponds to a side wall portion of the outer casing. The frame body 52 does not contact the attachment portion 14. A gap (air layer) is formed between the frame 52 and the attachment portion 14.

  The frame body 52 is connected to the instrument body 11 by being rotated in a state where the instrument body 11 is disposed in the upper opening. Specifically, the inner wall of the frame body 52 is formed with a female screw that is screwed with a male screw formed on the side wall portion 13 of the instrument body 11. The instrument body 11 and the frame body 52 are connected by rotating and screwing the male screw and the female screw.

Consider a case where the translucent cover 50 is suspended. In this case, a gap S having a predetermined interval may be formed between the reflecting plate 40 and the translucent cover 50. For example, the first string member 24 may be attached to one end of the instrument body 11 and the second string member 25 may be attached to the other end. Specifically, as shown in FIG. 6, when the illuminating device 10 is viewed in plan, the first string attachment portion 28 is X-axis with respect to a center line A parallel to the Z-axis that bisects the illuminating device 10. It is good to be located in the negative direction side, and the 2nd string attachment part 29 is good to be located in the X-axis positive direction side.

In this case, the first string member length L1 and the second string member length L2 are set so that a gap S1 having a predetermined interval is formed between the reflecting plate 40 and the translucent cover 50. Good.

  For example, when the thickness of the reflection plate 40 (width in the Z-axis direction) is 20 mm and the thickness of the translucent cover 50 (width in the Z-axis direction) is 80 mm, the first string attachment portion 28 of the instrument body 11 and the second The distance between the two strap attachment portions 29 is greater than 100 mm. In this case, as shown in FIG. 5, the length L3 from the first string attachment portion 28 to the outer diameter of the instrument body 11 is 32 mm, and the length L4 from the second string attachment portion 29 to the outer diameter of the instrument body 11 is L4.

Specifically, the first restricting portion 130 is erected in the normal direction of the main surface 12a of the base portion 12, and the other end on the opposite side to the one end connected to the main surface 12a is negative on the Y axis. It has a shape bent in an L shape toward the direction side. When the reflector 40 is suspended from the first string member 24 with the lighting device 10 attached to the wall surface W of the construction material B, the first string member 24 is disposed so as to be caught by the first restricting portion 130. . By doing so, the reflecting plate 40 is positioned on the X-axis negative direction side when the reflecting plate 40 is suspended from the first string member 24 as compared with the case where the first restricting portion 130 is not provided. . That is, when the translucent cover 50 and the reflection plate 40 are suspended with the lighting device 10 attached to the wall surface W of the construction material B, the distance from the center of the lighting device 10 in plan view is the first string attachment portion. Since the lighting device 10 includes the first restricting unit 130 at a position that is further in the horizontal direction than 28, the translucent cover 50 and the reflection plate 40 are less likely to interfere with each other.

  In addition, the lighting device 10 has a second restricting portion to which the second string member 25 is caught when the translucent cover 50 is suspended from the second string member 25 in a state where the lighting device 10 is attached to the wall surface W of the construction material B. 131. By doing so, the translucent cover 50 is positioned on the X axis positive direction side when the translucent cover 50 is suspended from the second string member 25 as compared to the case where the second restricting portion 131 is not provided. It becomes. That is, when the translucent cover 50 and the reflecting plate 40 are suspended with the lighting device 10 attached to the wall surface W of the building material B, the distance from the center of the lighting device 10 in plan view is the second string attachment portion. Since the illuminating device 10 includes the second restricting portion 131 at a position that is further in the horizontal direction than 29, the translucent cover 50 and the reflecting plate 40 are less likely to interfere with each other.

  Note that, as shown in FIG. 9, in the present embodiment, the second regulating unit 131 is a part of the lighting control device 70. Thus, each function of the 1st control part 130 and the 2nd control part 131 may be achieved by arrange | positioning suitably the components, apparatus, mechanism, etc. with which the illuminating device 10 is provided. Alternatively, parts, devices, and mechanisms that satisfy the functions of the first restricting portion 130 and the second restricting portion 131 in the lighting device 10 (functions that restrict the movement of the first string member 24 and the second string member 25 in the X-axis direction). Etc. may be provided separately. For example, the illuminating device 10 may be changed in the position of the mounting portion 14 so as to have the function of the first restricting portion 130 described above, or is newly erected on the base portion 12 as the second restricting portion 131. A support may be provided.

  Moreover, the storage battery 60 is mounted on one end side of the instrument main body 11, and at least one of the first string member 24 and the second string member 25 is preferably attached to the other end side. Specifically, when the lighting device 10 is attached to the wall surface W of the building material B, the storage battery 60 is in the negative Y-axis direction with respect to the center line A1 parallel to the X axis that bisects the lighting device 10 in plan view. The first string attachment portion 28 and the second string attachment portion 29 are preferably located on the Y axis positive direction side. More specifically, when the lighting device 10 is attached to the wall surface W of the construction material B, the storage battery 60 is positioned vertically above the appliance body 11 in plan view, and the first strap attachment portion 28 and the second strap The attachment portion 29 may be positioned on the vertically lower side of the instrument body 11.
