  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 on. 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 reflecting plate 40 reflects the 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.

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 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.

  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.

Moreover, the illuminating device 10 is attached to the wall surface of the construction material so that the light from the light emission part 30 may be emitted to the Z-axis positive direction side. In the description, it is assumed that water flows in the direction of the white arrow shown in FIG. Moreover, the illuminating device 10 shown by FIG. 10 is sectional drawing cut | disconnected along the position corresponding to the VI-VI line shown by FIG.

  Consider a case where water such as rainwater has been applied to the lighting device 10 from above the lighting device 10. In this case, water reaches the recess 22 through the gap between the frame body 52 and the side wall portion 13. Thereafter, the water travels along the outer peripheral surface 13a of the side wall portion 13 and reaches the concave portion 22 located on the lower side of the lighting device 10 (corresponding to the one-dot chain line shown in FIG. 10). The water further travels down the inclined surface 52b provided in the frame body 52 and goes out below the lighting device 10. When the concave portion 22 is positioned on the base portion 12 side of the male screw portion 23 and the frame body 52 and the side wall portion 13 are overlapped with each other, Water that tends to enter the lighting device 10 through the gap between the side wall portion 13 is less likely to enter the lighting device 10 due to the recess 22. That is, even when the lighting device 10 is attached to the wall surface W of the construction material B, the side wall portion 13 is provided with the recess 22 and the frame body 52 is provided with the inclined surface 52b on the inner peripheral surface 52a. Water such as rainwater applied to the lighting device 10 is less likely to enter the lighting device 10. Moreover, the recessed part 22 is provided in the side wall part 13, and the inclined surface 52b is provided in the inner peripheral surface 52a of the frame 52, so that water such as rainwater applied to the lighting device 10 is illuminated through the recessed part 22. It becomes easy to move to the exterior of the apparatus 10.

[Effects]
As described above, the illuminating device 10 includes the light emitting unit 30, the fixture main body 11 having the light emitting unit 30, the flat base portion 12, and the side wall portion 13 erected on the periphery of the base portion 12. A frame 52 that is detachably attached by engaging with the instrument body 11, and a translucent cover 50 having a light transmissive member 51 that transmits light emitted from the light emitting unit 30. The outer peripheral surface 13a of the side wall portion 13 is provided with an engaging portion 23 that engages with the translucent cover 50 and a concave portion 22 that is recessed inward with respect to the instrument body 11 and extends in the circumferential direction.

  Thus, when the lighting device 10 is attached to the wall surface W of the construction B, water such as rainwater applied to the lighting device 10 flows through the recess 22, that is, along the outer periphery of the lighting device 10. Move down. Thereby, it is suppressed that water penetrate | invades into the inside of the illuminating device 10. FIG. Therefore, according to the illuminating device 10, waterproofness is improved.

  Further, the frame body 52 may have a cylindrical shape having a female threaded portion 53 on the inner peripheral surface 52a, and the engaging portion 23 may be a male threaded portion that is screwed with the female threaded portion 53. Further, in the direction perpendicular to the main surface 12 a of the base portion 12, the concave portion 22 may be positioned closer to the base portion 12 than the male screw portion (engagement portion) 23.

  In this way, when the lighting device 10 is attached to the wall surface W of the construction material B, the frame 52 and the side wall portion 13 are most likely to allow rainwater or the like applied to the lighting device 10 to enter the lighting device 10. A recess 22 is formed in the vicinity of the threaded portion (the male screw portion 23 and the female screw portion 53). For example, the water that travels along the wall surface W of the building material B toward the inside of the lighting device 10 flows into the recess 22 before reaching the screwing portion. That is, water moves down the lighting device 10 along the outer periphery of the lighting device 10. Thereby, it is suppressed more that water penetrate | invades into the inside of the illuminating device 10. FIG. Therefore, according to the illuminating device 10, waterproofness is improved.

  Further, in the direction perpendicular to the main surface 12a, the instrument main body extends from the end surface 54 side of the frame body 52 located on the base portion 12 side to the inner peripheral surface 52a of the frame body 52 located on the base portion 12 side relative to the concave portion 22. 11 may be provided so as to extend in the circumferential direction.

  Thereby, when water, such as rain water, flows through the recessed part 22 and reaches the lower part of the illuminating device 10, it is difficult for water to collect in the illuminating device 10. Therefore, according to the illuminating device 10, waterproofness is improved more.

  Further, the end surface 54 of the frame body 52 located on the base portion 12 side may be provided with a convex portion 55 at least partially protruding from the end surface 54. Further, the side wall portion 13 may have a flange-shaped flange portion 21 that protrudes outward with respect to the instrument body 11 and is formed so as to cover the convex portion 55. Further, the convex portion 55 may extend in the circumferential direction of the end surface 54. Moreover, the collar part 21 is extended in the circumferential direction of the outer peripheral surface 13a.

  Thereby, when the illuminating device 10 is attached to the ceiling surface C of the building material B, for example, water such as rainwater that has reached the illuminating device 10 through the ceiling surface C is less likely to enter the interior of the illuminating device 10. Therefore, according to the illuminating device 10, waterproofness is improved.

  Moreover, the illuminating device 10 may further include a packing 110 that extends in the circumferential direction of the outer peripheral surface 13a on the base portion 12 side of the concave portion 22 in the direction perpendicular to the main surface 12a of the base portion 12.

  Accordingly, the frame body 52 and the side wall portion 13 are easily brought into close contact with each other (screwed). Therefore, the translucent cover 50 is unlikely to be detached from the instrument body 11.

  Moreover, the illuminating device 10 may further include a reflecting plate 40 on which the light emitting unit 30 is placed, reflects light emitted from the light emitting unit 30, and is detachably attached to the instrument body 11.

  That is, the light emitting unit 30 that is the light source of the illumination device 10 is detachably attached to the illumination device 10. Therefore, according to the illuminating device 10, when the light emission part 30 fails, the light emission part 30 is easy to replace | exchange.

  Further, when viewed in plan, the light emitting unit 30 may be disposed at the center of the reflecting plate 40. Further, the reflecting plate 40 may have a shape in which the opening area increases as the distance from the light emitting unit 30 increases.

  Specifically, the reflecting plate 40 includes a mounting surface 41 on which the light emitting unit 30 is mounted, and an inclined portion 42 that is inclined and extends with respect to the mounting surface 41. Thereby, the light emitted from the light emitting unit 30 reflected by the inclined unit 42 is more efficiently guided to the outside of the lighting device 10.

  The lighting device 10 may further include a storage battery 60 that is covered with the reflector 40 and placed on the base unit 12 and supplies power to the light emitting unit 30.

  Accordingly, the lighting device 10 is supplied with power from the storage battery 60 to the light emitting unit 30 even when a power failure or the like occurs. Therefore, for example, even when a disaster or the like occurs, the light emitting unit 30 can emit light even when power is not supplied from the external AC power supply.
