知ではある。2. Description of the Related Art In recent years, infrared remote control type lighting equipment has been actively developed. However, in order to avoid the adverse effect of the infrared light of the lamp and to improve the infrared remote control performance surely, the external equipment There is an example in which an infrared remote control signal receiving section is provided. However, in order to improve the appearance of the device, it is more appropriate to provide the receiving portion in the light-transmitting cover, and of course, such an example is known.

点もあった。However, if the lighting equipment that covers the chassis provided with the lamp and the infrared remote control signal receiving portion with the translucent cover is easily constructed,
In many cases, the infrared remote control signal from the transmitter causes the lamp to blink or the dimming control to malfunction or not operate. This is because the receiver is installed right below the chassis, and thus the infrared light of the lamp reflected by the bottom surface of the translucent cover is likely to enter the receiver. Furthermore, this malfunction or non-operation is remarkable when the lamp is lit at a high frequency. This is because the high frequency lighting frequency and the infrared remote control signal frequency are close to each other. For example, the high frequency lighting frequency is about 40 kHz to 60 kHz, and the infrared remote control signal frequency is 33 kHz.
This is because it is selected in the range of Hz to 40 kHz.
In addition to this, there is a problem that the allowable incident angle of the receiving section is narrow.
