More specifically, the contact portion 41 of the chassis 4 is disposed on and in contact with the periphery of the opening 71 on the back side of the light guide plate 7. The contact of the contact portion 41 of the chassis 4 with the back side of the light guide plate 7 may be performed directly or indirectly.

  Further, the peripheral edge portion on the front surface side of the opening 71 in the light guide plate 7 is supported by the flange portion 52 on the lower end side of the adapter guide 5. Furthermore, as representatively shown in FIG. 7, the outer peripheral edge of the light guide plate 7 on the front side is supported by the inclined portion of the bottom wall 92 in the main body frame 9. On the other hand, the reflection plate 3 is disposed on the back side of the light guide plate 7, and the light guide plate 7 has an inclined shape of the reflection plate 3, the flange portion 52 of the adapter guide 5 and the bottom wall 92 of the main body frame 9. It arrange | positions so that it may be pinched | interposed by a part. In this state, the light incident end surface 72 of the light guide plate 7 is positioned to face the light emitting element 61 so that light emitted from the light emitting element 61 is incident thereon.

  As shown in FIGS. 1, 4, and 5, the auxiliary component unit 8 is disposed outside the light emitting region of the light guide plate 7 as a light emitting unit and at the outer peripheral edge. Therefore, it is possible to avoid forming a dark portion in the light guide plate 7 by the auxiliary component unit 8, that is, the auxiliary component. In addition, since the auxiliary component unit 8 is provided with a plurality of electrical auxiliary components such as the infrared remote control signal receiving unit 84 in a centralized manner, wiring processing and assembly work can be made more efficient. Furthermore, since it is arrange | positioned in an outer periphery part, the improvement of design property can be anticipated without being conspicuous.

  As shown in FIGS. 3, 5, and 7, a gap G is formed between the side wall 91 of the main body frame 9 and the mounting piece 32 of the reflecting plate 3. That is, the outer shape of the reflecting plate 3 is smaller than the frame-shaped main body frame 9, and the gap G is formed over the entire circumference of the reflecting plate 3. The heat generated from the light emitting element 61 by the gap G is radiated by the convection action through the mounting plate 63. In order to promote this convection action, an air circulation hole may be formed in the bottom wall 92 of the main body frame 9.

  Next, the attachment state to the ceiling surface C of a lighting fixture is demonstrated with reference to FIG.12 and FIG.13. In addition, illustration of the power cord derived | led-out from the adapter A is abbreviate | omitted in each figure.

  As shown in FIG. 12, a hanging ceiling body Cb is installed on the ceiling surface C. The adapter A is electrically and mechanically connected to the hooking sealing body Cb. From this state, as shown by the arrow in the figure, until the engaging portion 51 of the adapter A is engaged with the engaging port 51 of the adapter guide 5 while the engaging port 51 of the adapter guide 5 in the instrument main body 1 is aligned with the adapter A.

  Further, when removing the instrument main body 1, it can be removed by removing the cover member 10 and operating the lever provided on the adapter A to disengage the engaging portion A 1 of the adapter A.

  When electric power is supplied to the lighting device 2 in the mounted state of the lighting fixture, the light emitting element 61 is energized through the substrate 62, and each light emitting element 61 is lit. The light emitted from the light emitting element 61 enters the light incident end surface 72 of the light guide plate 7, and the incident light is totally reflected within the light guide plate 7 and spreads over the entire light guide plate 7, and is formed on the back side. The light diffused and reflected by the dot pattern composed of the reflective dots is radiated from the light emitting region on the front side. In addition, a part of the light leaking from the light guide plate 7 is reflected by the reflecting plate 3 and radiated to the front side to be reused.

  Further, by operating the infrared remote control transmitter R toward the infrared remote control signal receiving unit 84, the light emission state of the light emitting element 61 in the light source unit 6 can be controlled. In this case, the infrared remote control signal receiver 84 is positioned substantially the same as the bottom wall 92 of the main body frame 9 or slightly protruding from the bottom wall 92, so that it is easy to receive the infrared remote control signal.

  Furthermore, as shown in FIG. 14, the lighting fixture of this embodiment may be installed in the same lighting space, for example, in the same room in a mixed manner with other lighting fixtures using a light source as a light source.

  In this case, since the lighting fixture of this embodiment uses the light source as the light emitting element 61, the infrared rays are hardly contained in the emitted light. Therefore, since the light emitted from the light emitting element 61 acts on the infrared remote control signal receiving unit 84 as noise and hardly causes a problem, the noise countermeasure structure is not a strict structure. In other words, for example, the noise countermeasure structure can be simplified without providing a bandpass filter or the like.

  For this reason, when the lighting fixture of this embodiment and other lighting fixtures are installed together, the irradiation light (infrared rays) from the other lighting fixtures is sent to the infrared remote control signal receiver 84 of the lighting fixture of this embodiment. There is a possibility of acting. However, in the lighting fixture of this embodiment, since the auxiliary component unit 8 (infrared remote control signal receiving unit 84) is disposed on the outer peripheral edge, as shown in the figure, the auxiliary component unit 8 is kept away from other lighting fixtures. Thus, the arrangement direction can be adjusted and installed.

  Therefore, even when the lighting fixture of this embodiment and other lighting fixtures are installed in a mixed manner, it is possible to suppress the noise caused by the irradiation light from other lighting fixtures, and the infrared remote control transmitter R Control can be ensured.

  Further, the heat generated from each light emitting element 61 is conducted from the back surface side of the substrate 62 to the mounting plate 63 and is radiated by a convection action promoted by the gap G between the main body frame 9 and the reflecting plate 3. Furthermore, the heat conducted to the mounting plate 63 is conducted to the reflecting plate 3 and is effectively radiated over a wide area of the reflecting plate 3.

  The auxiliary component unit 8 may be provided so that a plurality of electrical auxiliary components are gathered, and the specific configuration thereof is not limited. Further, although a plurality of electrical auxiliary components are provided in the auxiliary component unit 8 in a centralized manner, it does not prevent the specific electrical auxiliary components from being distributed. It is only necessary that electrical auxiliary parts are provided in the auxiliary part unit 8 in a concentrated manner. This makes it possible to achieve the desired effect.

  As described above, according to the present embodiment, it is possible to avoid the formation of a dark part in the light emitting part by the auxiliary component, and it is possible to suppress the luminance unevenness of the light emitting part. In addition, since a plurality of electrical auxiliary components are provided in the auxiliary component unit 8 in a centralized manner, the efficiency of wiring processing and assembly work can be improved. Furthermore, for example, even when the lighting fixture of the present embodiment is installed in a mixed manner with other lighting fixtures, the infrared remote control signal receiving unit 84 is suppressed from receiving noise due to light emitted from other lighting fixtures. Thus, the control by the infrared remote control transmitter R can be ensured. In addition, since the auxiliary component unit 8 is disposed at the outer peripheral edge portion, the design can be improved without conspicuous.

The same or corresponding parts are denoted by the same reference numerals, and redundant description is omitted. .

In the present embodiment, the auxiliary component unit 8 is disposed so as to protrude to the outside of the main body frame 9 on the outer peripheral edge of the instrument main body 1. The auxiliary component unit 8 is located on the back side, that is, on the ceiling surface C side from the bottom wall 92 of the main body frame 9. Therefore, the infrared remote control signal receiver 84 is also positioned on the back side of the bottom wall 92 of the main body frame 9 (see also FIG. 7). In other words, the infrared remote control signal receiving unit 84 is disposed on the outer peripheral edge portion of the instrument body 1 so as to be positioned above the bottom side that is the irradiation direction of the light emitting unit. Further, the outer peripheral portion of the main body frame 9 is formed in an R-shaped inclined shape S.
With such a configuration, the arrangement structure of the auxiliary component unit 8 can be simplified, and the auxiliary component unit 8 can be reduced from being noticeable in appearance.

  Further, in this case, as shown in the figure, when the infrared remote controller transmitter R is operated from the side opposite to the outer peripheral edge where the auxiliary component unit 8 is located, the main body frame 9 becomes an obstacle to reception, and the infrared remote controller signal receiver 84 may be difficult to receive the infrared remote control signal.

However, in the present embodiment, the part of the instrument main body 1 that is in close proximity to the auxiliary component unit 8 is formed in an inclined shape S toward the center, so that it is possible to easily receive an infrared remote control signal. Specifically, the main body frame 9 positioned inside the auxiliary component unit 8 is formed in an R-shaped inclined shape S toward the central portion. The R-shaped inclined shape S may be formed into a linear inclined shape S. In short, any configuration of the inclined shape S that can easily receive an infrared remote control signal may be used.

  On the back side of the instrument body 1, a plurality of (four) substrates 62 on which a plurality of light emitting elements 61 are mounted as light sources are disposed so as to surround the central portion. In addition, a translucent cover Cv is provided on the front side of the substrate 62 to cover them. Therefore, the light emitted from the light emitting element 61 is radiated to the outside through the translucent cover Cv, and the translucent cover Cv functions as a planar light emitting unit having a predetermined light emitting region. Further, the auxiliary component unit 8 is disposed outside the light emitting region and on the outer peripheral edge.

Note that the translucent cover Cv is not necessarily required. For example, when the translucent cover Cv is not provided, the surface of the substrate 62 on which the light emitting element 61 is mounted functions as a light emitting unit having a light emitting region.
