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. .

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.

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.

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.
