  FIG. 7 is a block diagram illustrating a configuration of a control system of lighting apparatus 100 according to Embodiment 1. The power supply unit 41 is connected to the AC power supply 210 via the adapter 1 and the hooking sealing body 200. The power supply unit 41 is mounted on the power supply board 4, the rectifier circuit that rectifies the current supplied from the AC power supply, the transformer that converts the rectified voltage into a predetermined voltage, and supplies a constant current. As described above, it is provided on the substrate holding portion 22 of the chassis 2 of the lighting device 100.

  Similarly, the power supply unit 41 is connected to a control board 5 provided on the board holding unit 22 of the chassis 2 and a dimming circuit unit 52 having electronic components mounted on the control board 5. The unit 41 supplies power of a predetermined voltage to the dimming circuit unit 52.

  As described above, a plurality of illumination modules 3 provided in the light source holding unit 24 of the chassis 2 are connected to the dimming circuit unit 52. The light control circuit unit 52 is connected to a control unit 5 provided on the substrate holding unit 22 of the chassis 2 and a control unit 51 having electronic components mounted on the control substrate 5. The control unit 51 is a microcomputer including a CPU and a storage element connected to each other via an internal bus, and controls each component of the lighting device by the operation of the CPU according to a control program stored in the storage element. It is configured.

  The control unit 51 is connected to an operation unit 56 provided at an appropriate position in the illumination device 100 and a signal receiving unit 55 that is a light receiving unit that receives infrared rays from the signal transmission unit 101 such as a remote controller. The operation unit 56 and the signal transmission unit 101 include, for example, a power switch that accepts an operation to turn on / off, a switch that accepts a brightness setting operation, and the like, and gives a signal corresponding to the operation to the control unit 51.

  The control unit 51 gives a control signal to the dimming circuit unit 52 based on the signal from the signal transmission unit 101 received by the signal reception unit 55 and the signal from the operation unit 56 according to the program stored in the storage element.

  The dimming circuit unit 52 includes a switching element and the like, and is configured to open and close the switching element in accordance with a control signal given by the control unit 51. A constant current is supplied to the lighting module 3 according to the opening / closing operation of the switching element, and the lighting module 3 is lit at a predetermined brightness.

  In the lighting device 100 configured as described above, the power supply board 4 (the power supply section 41 including the power supply board 4) is arranged around the adapter 1 that is the mounting portion, and the illumination module 3 is provided around the power supply board 4. Therefore, the adapter 1, the power source 41, and the illumination module 3 are arranged so as not to overlap in the direction perpendicular to the attached member, in other words, in the protruding height direction from the attached member. As a result, the protruding height of the adapter 1, the power source 41, and the illumination module 3 from the attached member can be reduced, and the illumination device 100 can be thinned. And since it arrange | positions so that the adapter 1, the power supply part 41, and the illumination module 3 may not overlap on the one surface side of the chassis 2 which makes plate shape, the protrusion height of the illuminating device 100 from to-be-attached members, such as a ceiling. Therefore, the lighting device 100 can be further reduced in thickness.

  Moreover, in the illuminating device 100 which concerns on Embodiment 1, between the power supply part 41 and the illumination module 3 is partitioned off by the outer peripheral wall 64 of the power supply cover 6 provided around the power supply part 41, and a translucent cover. 7. The illumination module 3 is accommodated in a cavity formed by the outer peripheral wall 64 of the power supply cover 6 and the chassis 2. Thus, since the power supply unit 41 and the illumination module 3 are arranged separately in separate rooms, only the illumination module 3 can be sealed. As described above, the illumination module 3 and the power supply unit 41 are divided into separate rooms using the outer peripheral wall 64 of the power supply cover 6 as a partition frame. For example, the illumination device 100 should be attached to or detached from the attached member such as the ceiling. When the center cover 8 is removed, the vicinity of the power supply unit 41 is exposed to the outside. Even in this case, the sealed state of the illumination module 3 can be maintained. As a result, it is possible to prevent insects and the like from entering the illumination module 3 portion, and cleaning is unnecessary, which contributes to the convenience of the user. Further, since the sealing mechanism does not require a detaching mechanism for the translucent cover 7 that covers the light source module 3, the structure can be simplified and the cost can be reduced.

  In addition, since the heat conductor power supply cover 6 is fixed and thermally connected to the chassis 2, the heat generated by the lighting module 3, the power supply unit 41, and the like is transmitted to the chassis 2 and transmitted to the chassis 2. Since heat is transmitted from the power source cover 6 to the center cover 8 side of the lighting device 100, the heat can be dissipated to the air around the lighting device 100.

  And LED32 is used for the light source. Since the LED 32 is a small light source, the thickness of the light source portion can be reduced, the protruding height of the lighting device from the mounted member such as the ceiling can be reduced, and the lighting device can be thinned. Can do. Further, unlike the fluorescent tube, by using the LED 32, the annular portion 72 of the translucent cover 7 can be flattened, and the thickness of the light source portion can be reduced. Since the diffusion lens 33 is provided in the light emitting direction of the LED 32, the light from the LED 32 can be diffused over a wide range by the diffusion lens 33, and even if the distance between the translucent cover 7 and the LED 32 is reduced. Uniform light emission is possible. Therefore, by using the LED 32 as the light source, it is possible to reduce the thickness of the lighting device 100 while ensuring uniform light emission. In addition, since the light source can be uniformly emitted without the shape of the light source emerging, the lighting device 100 with good design can be provided.

  In the present embodiment, the power supply cover 6 also serves as a partition frame for partitioning the illumination module 3 and the power supply unit 41. However, the present invention is not limited to this, and the partition frame may be provided separately from the power supply cover.

  Further, in the above embodiment, the power supply cover 6 is made of a metal having a good thermal conductivity. However, the material of the power supply cover is not limited to this, and like the light-transmitting cover 7, it is made of a light-transmitting resin. Also good. In this case, the center cover is also made of a translucent resin. As a result, the central portion of the lighting device can be illuminated without newly providing an LED at the central portion of the lighting device. In addition, by employing a light guide plate as the center cover, it is possible to emit light uniformly around the center of the lighting device. As a result, it is possible to avoid giving the user a sense of discomfort and discomfort due to the dark central portion of the lighting device.

  Moreover, in the above embodiment, although the translucent cover 7 is integrally formed, it is not limited to this. For example, the annular portion 72 of the translucent cover is made of milky white translucent resin, and the side surface portion 73 and the back surface portion 74 are made of transparent translucent resin. Thereby, it becomes possible to illuminate the ceiling which is a member to be attached brightly.

  In the above embodiment, an LED is used as a light source. However, the present invention is not limited to this, and EL (Electro Luminescence) or the like may be used.

  Moreover, in the above embodiment, the illumination device that is detachably attached to the attached body such as the hooking ceiling body provided on the attached member such as the ceiling has been described as an example. This type of lighting device can also be applied.

  Furthermore, it goes without saying that the present invention can be implemented in variously modified forms within the scope of the matters described in the claims.

  The illumination device includes: a light source; a power supply unit that supplies power to the light source; a holder that holds the light source and the power supply unit; and an attachment unit that attaches the holder to a member to be attached. The power supply part and the attachment part are arranged on the holding body so as not to overlap each other with respect to the attached member.

  The light source, the power source for supplying power to the light source, and the mounting portion for mounting the light source and the holder for holding the power source to the mounting member are arranged so as not to overlap each other on the mounting member. Since it is arranged on the holding body, the protruding height of the light source, the power supply unit, and the mounting unit from the mounted member can be reduced, and the lighting device can be thinned.

  The holding body is characterized in that the light source, the power supply section and the mounting section are arranged on one surface side of the holding body.

  Since the light source, the power supply unit, and the mounting part are arranged on one surface side of the holding body, for example, by appropriately setting the shape of the holding body, the light source, the power supply part, and the mounting part are arranged in substantially the same plane. By doing so, the protruding height of the lighting device from the mounted member such as the ceiling can be further reduced, and the lighting device can be further reduced in thickness.

  The mounting portion is provided at substantially the center of the holding body, the power source portion is provided around the mounting portion, the light source unit is provided around the power source portion, provided on the holding body, and the power source portion. And a partition frame for partitioning between the light source and the light source.

  A mounting part is provided in the approximate center of the holding body, a power supply part is provided around the mounting part, a light source part is provided around the power supply part, and a partition frame for partitioning between the power supply part and the light source is held. It is provided on the body. Thereby, for example, even when the vicinity of the power supply unit is exposed to the outside by removing the cover in the vicinity of the attachment unit, the sealed state of the light source part can be maintained. As a result, insects and the like can be prevented from entering the light source portion, and cleaning is unnecessary, which contributes to the convenience of the user.

  A cover that covers the power supply unit; and the partition frame is a heat conductor that connects the holding body and the cover, and heat from the light source or the power supply unit is transferred to the cover through the holding body. It is made to do so.

  The partition frame is a heat conductor that connects the cover that covers the power supply unit and the holder, and heat from the light source or the power supply unit is transferred to the cover via the holder. Heat generated by the light source or the power supply unit is transmitted to the partition frame via the holding body, and further transmitted from the partition frame to the cover. By appropriately providing the cover, the heat is dissipated from the cover to the air around the lighting device. It becomes possible.

  The light source includes an LED.

  An LED is used as the light source. Since the LED is a small light source, the thickness of the light source portion can be reduced, the projecting height of the lighting device from the mounted member such as the ceiling can be reduced, and the lighting device can be thinned. it can.

  By arranging the light source, power supply unit, and mounting part on the holder so that they do not overlap each other on the mounted member, the protruding height from the mounted member can be reduced, and the lighting device can be made thinner can do.
