When inputting to 55, the encoder 55 controls the oscillator 57 according to the luminaire designation code and the falling command inputted through the luminaire designation code input unit 51 to output a luminaire lifting control signal through the antenna 59. Send.

In addition, the filter unit 604 of the receiving unit 60 receives and filters the lifting control signal transmitted from the transmitting unit 50 through the receiving antenna 59 to extract only a signal having a desired frequency (300 MHz) and amplifying unit. The amplification unit 606 outputs the signal output from the filter unit 604 to the first decoder 610 and the second decoder 612.

The first decoder 610 compares the luminaire designation code of the signal input from the amplifier 606 with the individual control luminaire designation code input from the first luminaire designation code input unit 609 and decodes the received signal if it is the same. To output a 4-bit lift control signal.

In addition, the second decoder 612 designates a group control luminaire for inputting the luminaire designation code of the signal input from the amplifying unit 606 from the second luminaire designation code input unit 611, similarly to the first decoder 610. In comparison with the code, the received signal is decoded and output.

That is, in order to elevate the luminaire 80 individually or in groups, one transmitting means 50 can be used while the receiving means 60 must exist one by one for every luminaire 80. When the group control luminaire designation code is transmitted by 50), the plurality of luminaires 80 are simultaneously received by the plurality of receiving means 60 in which the same luminaire designation code as the group control luminaire designation code transmitted from the transmission means 50 is input. As the elevating, it is possible to eliminate the hassle to lift the luminaire 80 one by one.

As described above, the data output from the first decoder 610 and the second decoder 612 is output as 4 bits D0, D1, D2, and D3. Outputs a rising control signal of 'and a falling control signal of' high '.

For example, when the lifting control signal transmitted from the transmitting means 50 is a signal for lowering the lamp 80, the rising control signal is output as 'low', and the falling control signal is output as 'high'.

When the lifting control signal transmitted from the transmitting means 50 is a signal for raising the lamp 80, the rising control signal is output as 'high' and the falling control signal is output as 'low' and the lamp 80 is stopped. In the case of a signal to make both the rising control signal and the falling control signal is output as 'low'.

When the second combination unit 710 receives the rising control signal of 'low' and the falling control signal of 'high' from the first combination unit 614, the solenoid driving control signal and the lifting unit according to the control signal are input. Outputs a motor drive control signal and a light source lighting control signal.

At this time, the first detection unit 702 and the second detection unit 704 of the second combination unit 710 detects whether the luminaire has reached a top dead center, thereby detecting a rising signal of 'high' and a falling of 'low'. The signal is input to the second combining unit 710.

For example, in the state where the luminaire 80 reaches the top dead center, the disk 777 shown in FIG. 10 is raised, and the micro switch 778 detects this and the falling detection switch SW5 is 'on'. The signal 'low' is input from the first sensing unit 702, and the signal 'high' is input from the second sensing unit 704 by turning off the rising detection switch SW6.

In addition, when the luminaire 80 is lowered, the disk 777 shown in FIG. 10 is lowered, and the micro switch 778 detects this and the lowering detection switch SW5 is 'off', so that the first sensing unit ( A high signal is inputted from 702, the rising detection switch SW6 is turned on, and a low signal is input from the second detection unit 704.

Therefore, when the lift control signal for lowering the lamp 80 from the transmitting means 50 is input to the second combination unit 710 when the lamp 80 reaches the top dead center and is fixed. A signal of 'low' is input from the first detector 702 and a signal of 'high' is input from the second detector 704 while the signal is input.

The second combination unit 710 receives the above signals and outputs a solenoid driving control signal of 'high' and a reverse rotation driving control signal of 'high' and controls light source lighting of 'low'. Output the signal.

Sparks do not occur when the electrode 82-3 formed at the upper side of the electrode 82-3 is separated from the electrode 780 formed inside the cylindrical tube 782 formed on the base panel 711.

On the other hand, when the user wants to raise the lowered lamp 80, the user operates the transmission means 50 to wirelessly transmit the lift control signal as follows.

That is, the user operates the luminaire designation code input unit 51 of the transmission means 50 to designate the luminaire 80 to be raised, and then 'turns on' the rise switch SW2 of the input unit 53 to encode the rise command. When inputting to 55, the encoder 55 controls the oscillator 57 according to the luminaire designation code and the rising command inputted through the luminaire designation code input unit 51 to control the luminaire elevation control signal through the transmission antenna 59. Send.

In addition, the filter unit 604 of the receiving unit 60 receives and filters the lifting control signal transmitted from the transmitting unit 50 through the receiving antenna 59 to extract only a signal having a desired frequency (300 MHz) and amplifying unit. The amplification unit 606 outputs the signal output from the filter unit 604 to the first decoder 610 and the second decoder 612.

The first decoder 610 compares the luminaire designation code of the signal input from the amplifier 606 with the individual control luminaire designation code input from the first luminaire designation code input unit 609 and decodes the received signal if it is the same. To output a 4-bit lift control signal.

In addition, the second decoder 612 designates a group control luminaire for inputting the luminaire designation code of the signal input from the amplifying unit 606 from the second luminaire designation code input unit 611, similarly to the first decoder 610. In comparison with the code, the received signal is decoded and output.

As described above, the data output from the first decoder 610 and the second decoder 612 is output as 4 bits D0, D1, D2, and D3. Outputs a rising control signal of 'and a falling control signal of' low '.

When the second combination unit 710 receives the 'high' rising control signal and the 'low' falling control signal from the first combination unit 614, the solenoid driving control signal and the lifting unit according to the control signal. Outputs a motor drive control signal and a light source lighting control signal.

At this time, the first detection unit 702 and the second detection unit 704 of the second combination unit 710 detects whether the luminaire 80 has reached the top dead center, so that the rising detection signal of 'low' and 'high' The falling detection signal of the input to the second combination unit 710.

Therefore, when the lifting control signal for raising the lamp 80 from the transmitting means 50 is input while the lamp 80 is lowered, a rising control signal of 'high' is input to the second combination unit 710. The 'high' signal is input from the first detector 702 and the 'low' signal is input from the second detector 704.

The second combination unit 710 receives the above signals and outputs a solenoid driving control signal of 'high' and a forward rotation driving control signal of 'high', and controls the light source lighting of 'low'. Output the signal.

Accordingly, the solenoid driving unit 720 operates to operate the relay RY1, the power is supplied to the solenoid 760, and the solenoid 760 operates to operate the stopper 778 operated by the solenoid 760. The state separated from the groove 82-1 of 80 is maintained.

Then, the motor driving unit 730 operates the relay RY2 so that the lifting motor 770 rotates forward, and supplies AC 220V power to the lifting motor 770 so that the lifting motor 770 rotates forward. do.

Therefore, the luminaire 80 lifting and lowering by the lifting motor 770 starts to ascend.
