Description of the Related Art With the widespread use of infrared remote control systems as means for remotely controlling electric equipment such as TVs and air conditioners, the number of lighting devices using infrared remote control systems has increased. There is. A conventional example of this type of lighting device is shown in FIGS. That is, the remote control signal S using infrared rays is transmitted from the transmission unit 80, the reception unit 81 provided in the lighting fixture main body 82 receives this, and the control circuit 83 controls the operation of the lighting circuit 84 to perform fluorescence. The lamp 85 is configured to be turned on, turned off, and dimmed.

外乱を除去している。The light source of the transmitter 80 uses a gallium arsenide (GaAs) type infrared light emitting diode having the characteristics shown by the curve A in FIG. Is used as.
On the other hand, the receiving section 81 has a light receiving sensitivity of a spectral characteristic as shown by a curve B in FIG. 9 by means of combining an optical filter with a silicon (Si) type light receiving element, and the visible light of sunlight or illumination light of the characteristic C. It is made to be optically distinguishable from. In addition to the optical characteristics described above, the carrier of the remote control signal is about 40 KHz (33 to 40 KH).
The high frequency pulse of z) is used, and even after the signal light is received by the receiver 81, disturbance is removed by performing electrical frequency selection so as to mainly extract these carrier signals.

くくなることがある。However, when the fluorescent lamp 85 is lit at a high frequency by the lighting circuit 84, in addition to the visible light as shown by the curve C in FIG. 9, the wavelength 1 as shown by the curve D in FIG.
It is conventionally known that a mercury spectrum near 013 nm is generated. The lighting frequency of the lighting circuit 84 is about 50 KHz, which is close to the frequency of the carrier wave of the remote control signal.
When the power of the remote control signal S reaching the receiving section 81 becomes smaller as the power of the remote control signal S reaches the receiving section 81, the influence of the mercury spectrum from the fluorescent lamp 85 becomes relatively large and the infrared remote control system becomes difficult to operate. There is.

It affects the reach of infrared remote control systems as well as the spectrum. This argon spectrum Ar
Has a property different from the mercury spectrum Hg generated during stable lighting by changing the time as shown in FIG. That is, the energy of the argon spectrum Ar is stronger than that of the mercury spectrum Hg immediately after lighting, and the amount of energy is reversed with the lapse of time after lighting, and the influence of the mercury spectrum Hg becomes large.

With respect to, a means for adding visible light and a spectrum of mercury by adding an optical filter having a spectral characteristic indicated by the curve F in FIG. 10 to the front surface of the receiving unit 81 and cutting wavelengths of 800 nm or less and 1000 nm or more is used. There is.

ル信号の分離は難しい。On the other hand, regarding the argon spectrum (near 920 nm and 970 nm) which is large at the beginning of lighting at low temperature and becomes small when the fluorescent lamp 85 stabilizes, the S / N ratio is lowered for 2 to 3 minutes immediately after lighting and the transmission signal is transmitted. Since it is hard to receive, a means for increasing the output of the transmission unit 80 was considered, but there was a problem that the loss of the power source was large. Since the emission spectrum of argon and the emission spectrum of the light emitting element are close to each other, it was difficult to select only the spectrum to be used by the optical filter. For example, if a vapor deposition film filter is used, an optical filter with sharp characteristics can be obtained, but since the wavelength changes depending on the incident angle of light, it is actually difficult to separate the argon spectrum and the remote control signal.
