  Hereinafter, the structure of the illuminating device which concerns on the Example of this invention is demonstrated using attached FIG. This lighting device is installed on the ceiling of a building, mainly a living room of a general household, and is connected to an external power source via an attachment adapter that engages with an indoor wiring device such as a hooking rosette or hooking ceiling attached to the building. In addition, it is used by being fixed at a predetermined position. FIG. 1 is an external perspective view of a lighting device 100 installed on a ceiling surface (not shown) as seen from the floor surface side. The diffusion cover 2 is a part made of a resin material such as acrylic or polystyrene having translucency that is transparent, translucent, or milky white. By providing the diffusion cover 2, there is an effect that a hand is prevented from touching the internal structure of the lighting apparatus 100. By making the diffusing cover 2 translucent or milky white, the illumination device 100 mainly diffuses light emitted from the light source unit 10 (described later), and reduces glare when the user looks directly at the illumination device 100. There is an effect that the brightness in the room where is installed is made uniform. Moreover, when the diffusing cover 2 is transparent, there is an effect that the illuminance directly below is improved as compared with a translucent or milky white one.

  FIG. 2 is a perspective view with the diffusion cover 2 removed, and FIG. 7 is an exploded perspective view of the lighting device 100.

  When the diffusion cover 2 and the adapter cover 101 are removed, the instrument mounting portion 102 provided at the center of the main body 1 formed of, for example, a metal plate can be seen. By engaging the claw-like hook portion of the mounting adapter with the appliance mounting portion 102, for example, it is fixed at a predetermined position on the ceiling surface of the living room. Further, a power supply connector (not shown) is disposed in the vicinity of the fixture mounting portion 102. By fitting and connecting the power supply connector and the connector disposed in the mounting adapter, indoor wiring of the building is provided. Power can be supplied from.

  The light source unit 10 integrally covers a semiconductor light emitting element mounting substrate to which the semiconductor light emitting element is soldered and connectors for electrically connecting the plurality of substrates, and press-fixes them to the main body 1. It is composed of a translucent substrate cover. The substrate cover has a function of preventing an electric shock by preventing a user from directly touching the semiconductor light emitting element mounting substrate and protecting the semiconductor light emitting element. In this embodiment, a large number of dome shapes are arranged, but a flat plate shape or the like can have the same function.

  The semiconductor light emitting element emits light and generates heat during operation, and the temperature of the semiconductor light emitting element rises itself. However, as the temperature rises, the light emission efficiency decreases. Therefore, it is necessary to provide an appropriate heat dissipation means corresponding to the temperature rise. . For this reason, the semiconductor light-emitting element mounting substrate uses an aluminum plate with an insulating layer or a resin plate with a high thermal conductivity formed with a copper foil pattern and a solder resist, and heat generated by the semiconductor light-emitting element is mounted on the semiconductor light-emitting element mounting board. Heat dissipation by heat conduction is ensured by directly radiating heat from the surface of the substrate or by closely attaching the semiconductor light emitting element mounting substrate to the main body 1 formed of a metal plate or the like.

The diffusion cover 2 covers the light source unit 10 and the diffusion cover attachment 7. The diffusion cover 2 is engaged and held by diffusion cover attachments 7 attached to two opposite sides of the main body 1.
The diffusion cover attachment 7 includes a detachable button 5, an arm 6, and an engagement claw 4. The arm 6 is a rod-like or plate-like member. Engaging claws 4 are provided at both ends of the arm 6, and a detachable button 5 is provided at a substantially central portion of the arm 6. When the attachment / detachment button 5 is pressed, the entire diffusion cover attachment 7 is moved to disengage the engagement pawl 4 from the engagement portion 9. Here, the member that transmits the operation of the attaching / detaching button 5 to the engaging pawl 4 is the arm 6, but any member may be used as long as the engaging pawl 4 is operated by the operation of the attaching / detaching button 5. The diffusion cover attachment 7 is attached to the main body 1 by an engagement claw cover 11 and a button cover 12. Further, the diffusion cover mounting tool 7 is disposed on two sides orthogonal to one side of the main body 1 on which the subunit 3 is disposed, and by a biasing means such as a coil spring (not shown), It is biased toward the outside of the main body 1. FIG. 6 shows a cross-sectional view of the engagement claw 4 and the engagement claw cover 11 in FIG. 3 is a view as seen from the floor side with the diffusion cover 2 removed, but FIG. 6, which is a sectional view taken along the line BB, shows the engagement pawl 4, the diffusion cover 2, and the engagement portion 9. In order to understand the positional relationship, a cross-sectional view with the diffusion cover 2 attached is shown. The engagement claw 4 is engaged with an engagement portion 9 provided on the diffusion cover 2 to hold the diffusion cover 2, and the detachment button 5 is pushed in against the urging force of the urging means, whereby the detachment button 5, the diffusion cover fixture 7 composed of the arm 6 and the engagement claw 4 moves in the direction of the arrow in FIG. 6 to disengage the engagement claw 4 from the engagement portion 9 and remove the diffusion cover 2. it can.

  As shown in FIG. 5, the subunit 3 is provided with a subunit substrate 8 on which an infrared remote control signal receiver, a safety light, an illuminance sensor, and the like are mounted. The outer parts of the subunit 3 are made of a non-translucent material so as not to be influenced by the light emitted from the light source unit 10. From the subunit 3, a harness (not shown) that is electrically connected to a lighting circuit board (not shown) disposed inside the main body 1 comes out. The subunit 3 is fixed to the main body 1 by, for example, screwing or the like. Yes. For this reason, it becomes easy to cope with changing the circuit configuration of the subunit substrate 8 depending on the specifications required for the lighting device 100 or not mounting the subunit 3 when the function provided by the subunit 3 is unnecessary. , Productivity can be improved.

  The subunit 3 is configured separately from the diffusion cover 2 and is disposed so as to project outside the diffusion cover 2 along one side of the outer periphery of the diffusion cover 2. Therefore, when the illumination device 100 is viewed from the floor side, the diffusion cover 2 and the subunit 3 are in a positional relationship that does not overlap, and a part of the diffusion cover 2 does not become a dark part. The floor surface can be made brighter. Further, the weight of the diffusion cover 2 can be suppressed, and the detachability operability of the diffusion cover 2 can be improved.

  Further, the diffusion cover mounting tool 7 attached to the main body 1 is disposed on two sides orthogonal to one side of the main body 1 on which the subunit 3 is disposed, so that the subunit 3 can be attached when the diffusion cover 2 is attached or detached. An easy-to-use lighting device can be realized without interfering with the operation of the detachable button 5.

  Further, in this embodiment, the external shape of the diffusion cover 2 when viewing the lighting device 100 from the floor side is rectangular, but the same effect can be obtained even in the case of a square. As in the case of the rectangular shape, the diffusion cover mounting tool 7 disposed on the main body 1 is disposed on two sides orthogonal to one side of the main body on which the subunit 3 is disposed. By disposing the joint portions 9 on all four sides of the diffusion cover 2, the diffusion cover 2 can be attached to the main body 1 regardless of the orientation, so that the usability can be further improved.

  As described above, the diffusion cover for diffusing the light emitted from the light source unit and the subunit having the infrared remote control signal receiving unit and the illuminance sensor are separately configured so that the diffusion cover can be attached and detached independently. At the same time, since the subunit is arranged so as to protrude outside the diffusion cover along one side of the outer periphery of the diffusion cover, when the lighting device is viewed from the floor surface side, the subunit is not disposed. The translucent part does not become a dark part of the diffusion cover, and a brighter illumination device can be realized.

  Further, according to this embodiment, the diffusion cover fixing means are arranged on two sides orthogonal to one side of the main body on which the subunit is arranged, so that the subunit can be attached and detached. Therefore, it is possible to realize a lighting device that is easy to use.

  In the present embodiment, the main body 1 is rectangular and the attachment position of the subunit 3 is provided on the short side of the main body 1, but is not limited thereto. When the attachment position of the sub unit 3 is on the long side of the main body 1, the diffusion cover attachment 7 is provided on the short side, but the structure in which the engagement claws provided on both ends of the side are connected by arms For example, the detachable button and the engagement claw can be integrated, and the diffusion cover 2 can be fixed at one central portion of the side.
