The discharge lamp 2 attached to the fixture main body 3 is electrically connected to the lighting circuit of the lighting circuit board 5 by the base 20 and lights up when electric power is supplied from the lighting circuit. Further, since there is no lamp light emitter in the vicinity of the base 20 and the light quantity of the lamp is small, the optical noise is smaller than other places. The discharge lamp 2 is not limited to a double annular type, and may be a single annular type.

  The instrument body 3 is formed in a disc shape with a metal plate or the like, for example, and includes a circular bottom surface portion 30, a step portion 31 extending upward from the outer edge of the bottom surface portion 30, and an outer edge of the step portion 31.

  The light receiving element 6 is provided with a light receiving surface 60 at the tip (see FIG. 3), and is disposed between the center of the instrument body 3 and the socket 38 while being accommodated in a resin-molded case 61. It is mounted on the lighting circuit board 5 so as to be disposed on the outer side of the mounting portion 34 in the short direction together with the nightlight LEDs 7. The light receiving element 6 mounted in this manner receives a remote control signal transmitted from a remote control transmitter (not shown), and outputs the received remote control signal to a lighting circuit configured on the lighting circuit board 5. Here, the light receiving performance of the remote control signal in the light receiving element 6 is expressed by the signal level ratio between the remote control signal level from the remote control transmitter (not shown) and the optical noise level. It can be said that the larger the signal level ratio, the better the light receiving performance of the remote control signal. Since the base 20 of the discharge lamp 2 does not have a lamp illuminant and light noise is reduced, it is preferable that the light receiving element 6 be disposed as close to the socket 38 as possible between the center of the fixture body 3 and the socket 38. .

  Each of the plurality of night-light LEDs 7... Is arranged around the light receiving element 6 with the same distance from the light receiving element 6.

Can be isolated from the heat generating component 51. On the other hand, the protective case 8 surrounds the operation switch 52 on the other end side in the longitudinal direction and has a function as an operation space portion 83.

  Without such a protective case 8, the light from each nightlight LED 7 diffuses, and if there is an obstacle before reaching the globe (not shown), the shape projected on the globe becomes distorted. However, by providing the protective case 8 as in the first embodiment, it is possible to limit the range of light spread and make the silhouette projected on the globe beautiful.

  By the way, the color of the protective case 8 is a color such as white that easily reflects light. This makes it easy to radiate light from each of the plurality of nightlight LEDs 7. Further, a more preferable resin material for the protective case 8 is a resin material having a low transmittance with respect to light having a wavelength from the visible region to the infrared region.

  Further, as shown in FIG. 3, the protective case 8 is provided with a lighting member 84 disposed in the center of the opening 80 when viewed from the normal direction of the mounting surface of the lighting circuit board 5. By arranging the daylighting member 84 in the center of the opening 80 as described above, the uniformity of light distributed from the plurality of nightlight LEDs 7... Is not hindered.

The end portion and the lighting circuit board 5 are attached with a gap. Thereby, even if the force from above is applied to the protective case 8, it is possible to prevent the lighting circuit board 5 from being stressed. The gap is not limited, but in the first embodiment, it is about 1 mm from the point that light does not leak. The lighting member 84 attached in this way transmits a remote control signal to the light receiving surface 60 through the inside of the cylindrical portion 840.

  The insulating cover 9 is for diffusion whose surface has been processed into a ground glass shape or a glass shape, and is covered with an opening 80 of the protective case 8 as shown in FIG. The emitted light from the plurality of night-light LEDs 7... Is diffused to make the light more uniform. As a result, it is possible to make a soft light that gently illuminates the entire room. On the other hand, since the insulating cover 9 can collect the remote control signal from the outside, the light receiving performance of the remote control signal in the light receiving element 6 can be stabilized without affecting the type of globe (not shown). Further, by covering the opening 80 with the insulating cover 9, it is possible to prevent the user from easily touching the plurality of nightlight LEDs 7... And the light receiving element 6.

For example, it is possible to reduce the number of connecting parts such as connectors and electric wires that are electrically connected to electronic parts of the circuit, and to mount a plurality of night-light LEDs 7... It is possible to do.

  In the discharge lamp 2 which is an annular lamp, the base 20 attached to the socket 38 does not have a lamp illuminant, and there is little optical noise with respect to the remote control signal. By arranging the light receiving element 6 between the two, the light receiving performance of the remote control signal in the light receiving element 6 can be improved compared to the case where the light receiving element 6 is arranged in another space. Further, in the disk-shaped instrument body 3, a plurality of night-light LEDs 7... And the light receiving element 6 are arranged on the outer side in the short direction of the mounting portion 34 having a larger space than the longitudinal direction of the mounting portion 34. Thus, the space can be used effectively.

  The protective case 8 surrounds the plurality of nightlight LEDs 7... And the light receiving element 6, and can block the heat generated from the heat generating component 51, so that it is transmitted to the plurality of nightlight LEDs 7. Heat to be reduced. Further, by providing the daylighting member 84 inside the protective case 8, the light receiving element 6 can mainly receive light from the normal direction of the mounting surface of the lighting circuit board 5 at the light receiving surface 60. For example, an optical filter (not shown) incorporated in the light receiving element 6 can be effectively acted, and the light receiving performance of the remote control signal in the light receiving element 6 can be sufficiently exhibited.

  By arranging the daylighting member 84 in the center of the surrounding member 82, the influence of the daylighting member 84 on the light radiated to the outside from each nightlight LED 7 can be reduced. Further, since the daylighting member 84 houses the light receiving element 6, the light receiving surface 60 of the light receiving element 6 can be isolated from each nightlight LED 7, so that the surrounding member 82 radiates from each nightlight LED 7. Optical noise due to irregularly reflected light can be reduced, and the light receiving performance of the remote control signal in the light receiving element 6 can be further improved.

  When the insulating cover 9 covers the opening 80 of the surrounding member 82 on one end side of the protective case 8, the possibility that the user accidentally touches the plurality of nightlight LEDs 7... And the light receiving element 6 can be reduced.
