FIG. 3 shows signal waveforms in the channel selection mode in the embodiment shown in FIG. FIG. 3A shows a signal waveform propagated by the infrared rays 15. First, a CH1ON signal indicating that channel 1 is on is transmitted, and then a CH1OFF signal indicating that the channel is off is transmitted. Thereafter, a signal for turning on and off the channels 2 and 3 follows.

FIG. 3B shows the lighting state of channel 1. The channel 1 is turned on in response to the CH1ON signal, and the lighting device 131 is turned on. When the CH1ON signal ends, channel 1 turns off and the lighting device 131

FIG. 4 shows the wireless transmitter 16 shown in FIG.
The operation of the transmitting microcomputer 20 in FIG. In step b1, the operation is started by turning on the power switch or the like. At step b2, various initial settings are made. For example, the mode is not the selection mode but the control mode for channel 1.

At step b3, the key matrix 23 is scanned. When the intersection points of the matrix are sequentially scanned and a key is pressed, the coordinates of the intersection point indicate the type of the key. Next, the process proceeds to step b4, and it is determined whether or not the channel selection mode is in progress. When not in the channel selection mode, it is determined in step b5 whether or not the mode key 17m is pressed. When any other key is pressed, it is decoded in step b6 and a code signal representing the contents of the key is generated. At step b7, a maker code and parity are added to the code signal. The signal code thus synthesized is transmitted in step b8.

When it is determined in step b5 that the mode key 17m is pressed, the operation mode is set to the channel selection mode in step b9. The current lighting state of each channel is stored, and each channel is turned off.
The channel number is initialized to 1.

When the channel selection mode is in effect in step b4, the process proceeds to step b10, and it is determined whether or not the selection key 17s is pressed. If there is no key input or if it is not the selection key 17s, the process moves to step b11 to check the timer. When the predetermined time, for example, the time in the range of 1 to 10 seconds, has not elapsed, the process moves to step b12 and the timer continues counting. When this time has elapsed, the process moves to step b13,
At the previous step b13, it is determined whether it was ON or OFF. If the previous time was OFF, an ON signal is generated in step b14. If it was ON last time, an OFF signal is generated in step b15, and the channel number is increased in step b16. At step b17, it is judged whether or not the increased channel number is larger than N which is the maximum value MAX of the channel numbers,
If it is larger, the channel number is returned to 1 in step b18. When step b14 or step b17 ends, the process moves to step b7.

When it is judged at step b10 that the selection key 17s is pressed, the routine proceeds to step b19, where the current channel number is stored and displayed by the channel number display 25.

Next, in step b20, the channel selection mode is released, and the respective lighting fixtures 131, 132, ..., 13N.
Returns to the lighting state stored in step b9. The above operation from step b3 to step b20 is repeated.

The N / OFF-controlled signal is given to the light emitter 24. This signal is provided as an input to the base of a transistor 41 which drives an infrared light emitting diode 40 in the light emitter 24. The infrared light emitting diode 40 emits infrared light having a wavelength of 940 nm.

On the side of the light receiver 13, the infrared light receiving diode 4
Infrared light transmitted from the infrared light emitting diode 40 is received by 2. The infrared light receiving diode 42 derives the current output i _P according to the amount of received light. This output current i _P causes a voltage drop v _out across the resistor 43. This voltage v _out is given to the carrier amplifier 45 via the capacitor 44. The carrier amplifier 45 has an amplification degree of 100 dB with respect to a signal having a frequency of 38 kHz. Since the output from the carrier amplifier 45 has a large amplification degree, it is almost saturated and becomes a signal in which a rectangular wave of 38 kHz is intermittent. This signal is detected by the detection circuit 46, and 5 V represents a logic "1" and 0 V represents a logic "0" on the signal line 14.

According to this embodiment, when a number of luminaires are sequentially controlled, the first channel 1 does not blink each time the channel selection mode is switched, and the selection is performed from the channel next to the previously selected channel. Since the blinking for is started, it is possible to quickly and quickly control all channels without waste.

FIG. 8 shows the appearance of a wireless transmitter 26 according to another embodiment of the present invention. The wireless transmitter 26 is similar to the wireless transmitter 16 shown in FIG. 2, and the corresponding parts bear the same reference numerals. It should be noted that a plurality of selection switches 27x, 27y, 27z are provided as the channel changeover switch 27, and the key matrix 28 is electrically configured together with the dimming switch 18 and the movable switch 19. Each of the plurality of selection switches 27x, 27y, and 27z can specify and select one channel. These selection switches 27x, 27y, 27z can call the selected channels respectively when the operation mode is not the channel selection mode. Further, when the mode switch 27m is pressed to switch to the channel selection mode, the selection switches 27x and 27 have already been selected.
Blinking control for channel selection is performed except for the channels designated by y and 27z. When canceling the selection by the selection switches 27x, 27y, 27z, for example, the selection switches 27x, 27y, 27z are selected.
And the mode key 27m may be pressed at the same time.

Then, it is to judge whether or not the channel number at that time has already been selected. If already selected, the process returns to step b16. The code generation and transmission in steps b7 and b8 shown in FIG. 4 are performed only when not selected. Thereby, for example, when the selection switch 27x, 27y, 27z in the selected state is pressed while the channel selection mode is switched and the respective channels are sequentially lit, the selection switch 27x, 27y, 27z is operated. A selection is made, and control for that channel becomes possible in the same manner as shown in FIG. Since the blinking control is not performed for the channels already selected by the other selection switches 27x, 27y, 27z, there is no risk of duplicate selection even if the remaining selection switches 27x, 27y, 27z are pressed. Further, the channels selected by the respective selection switches 27x, 27y, 27z can be immediately called by pressing the selection switches 27x, 27y, 27z in the modes other than the channel selection mode. Frequently used channels can be easily called by selecting a frequently used channel.

In each of the above-mentioned embodiments, in order to select a channel, the lighting device 130 belonging to that channel is turned on, but not only is it turned on,
It goes without saying that flicker that repeats blinking in a short cycle may be performed. By flickering the lighting device 130, it is possible to easily know which channel is lit even when many lighting devices 130 are provided.

Further, the case where the movable control and the dimming control of the plurality of movable lighting devices 100 are described, however, only the dimming control may be performed for the plurality of fixed lighting devices. Of course. Even if many lighting devices are installed on the ceiling and the dimming control is performed for each channel by remote control, it is not necessary to know the relationship between the channel assignment and the lighting device, and simple and reliable control can be performed. You can

Further, the transmission of signals for remote control is
Although infrared rays are used, it goes without saying that wireless means such as radio waves or ultrasonic waves, or wired remote control via signal lines may be used. When using infrared rays, a signal can be easily generated by the infrared light emitting diode, the wireless transmitter 6 can be downsized, and portability can be improved.
