Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device which is turned on / off by a wall operation switch.

[0002]

2. Description of the Related Art A lighting device installed on a ceiling is usually turned on and off by a wall operation switch arranged on a wall surface. In this case, as shown in FIG. 3 and the wall surface operation switch 2 are connected by the falling wiring 30 embedded in the wall. Reference numeral 35 in the figure is a breaker.

[0003]

In this case, the luminaire 1
Each time the fall wiring 30 is required, and the labor of the electric wiring work becomes considerable. The wall operation switch 2 is configured as a wireless switch using infrared rays so that the fall wiring 30 can be eliminated, and a receiver 5 for receiving a control signal by infrared light from the wall surface operation switch 2 is provided on the ceiling surface 4. A receiver which is installed and receives the control signal from the wall surface operation switch 2 so that the receiver 5 turns on and off the lighting fixture 1 has been put into practical use, but this one receives the control signal by infrared light. In addition, the light receiving surface of the receiver 5 has to be exposed to the ceiling surface 4, which is not preferable in terms of the design of the ceiling surface.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a lighting device which does not require a down wiring and causes no problem in design of a ceiling surface. To provide.

SUMMARY OF THE INVENTION The present invention, however, is an illuminating device comprising a wall operation switch and a luminaire whose on / off control is performed at least by the wall operation switch. The operation input is converted into a control signal. A reception control unit that receives a control signal from a wall operation switch equipped with a transmission unit that transmits weak wirelessly and operates a switching member inserted in a power line to a lighting fixture is provided in the ceiling. It has a feature that it has a wireless structure and that the reception control unit can be arranged in the ceiling.

At this time, the identification code of the luminaire is added to the control signal transmitted by the transmission section of the wall surface operation switch, and the reception control section puts the plurality of luminaires under its control and responds to the identification code in the control signal. If the corresponding switching member for the lighting equipment is operated, it is not necessary to provide a reception control unit for each lighting equipment, which is advantageous in terms of cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 and 2, a wall surface operation switch 2 is a control unit 2 including a microcomputer or the like.
0, an RF transmitter 21, an antenna 22, and a battery 23 as a power source are built-in, and an operation input such as on / off is converted into a control baseband signal in the controller 20, and the RF transmitter 21 controls this. Baseband signal is A
Modulation such as SK or FSK is performed, and the signal is transmitted from the antenna 22 by weak radio in the 400 MHz band, for example. The control baseband signal includes, for example, a start bit, an ID code, an ID code parity bit, a control code, a control code parity bit, and a stop bit.
The ID code is an identification code for preventing a malfunction of a different device, and is set as a pair with the corresponding receiving device side so that the EEP
It is set by ROM or the like.

On the other hand, a switching member 7 which is a relay contact opened and closed by the reception control unit 6 is inserted in the power line 3 reaching the lighting fixture 1 installed on the ceiling surface 4. The reception control unit 6 here, as shown in FIG.
An antenna 64 for receiving weak radio waves from the wall surface operation switch 2, an RF receiver 60 for demodulation, a microcode for collating an ID code and its parity bit from a demodulated control baseband signal and decoding a control code. The lighting device 1 is turned on and off by opening and closing the switching member 7 by the relay 62, which includes a control unit 61 including a computer and the like, a relay 62 that operates by the output of the control unit 61, and a power supply unit 63. The switching member 7 may be composed of a switching element such as a triac.

In this illuminating device, when the wall surface operation switch 2 is operated, a control signal corresponding to the operation input is weakly transmitted wirelessly, and the luminaire 1 corresponding to the reception control section 6 installed in the back of the ceiling. To turn on and off
For this purpose, the wall operation switch 2 is passed from the back of the ceiling through the inside of the wall.
In addition to the fact that the fall wiring to the above is unnecessary, and since the reception control unit 6 can be installed in a place where the ceiling is not exposed, the design problem of the ceiling surface 4 does not occur. .

Another example is shown in FIGS. In the above description, the reception control unit 6 is installed in a one-to-one correspondence with the lighting fixture 1, but here, the plurality of switching members 7 inserted in the respective power supply lines of the plurality of lighting fixtures 1 are separated. It can be controlled by one reception control unit 6,
In addition to the ID code and the control code, a fixture identification number code unique to each lighting fixture 1 is also added to the control baseband signal transmitted from the wall surface operation switch 2 in accordance with this, and the reception control section 6 uses this fixture. The identification number code is used to determine which wall operation switch 2 the signal is from, and the switching member 7 for the lighting fixture 1 to which the corresponding fixture number code is attached is opened or closed. Reference numeral 24 in FIG. 4 denotes a device identification number code setting unit.

When there are a large number of lighting fixtures 1, installing the same number of reception control units 6 causes a cost problem.
In this way, by placing a plurality of lighting fixtures 1, for example, all the lighting fixtures 1 on the first floor of the house under the control of a single reception control unit 6, the problem of cost can be avoided. It should be noted that the wall surface operation switch 7 does not have to be fixed to the wall surface and is, for example, always arranged in a pocket provided on the wall surface, but it can be taken out of the pocket and operated when necessary. It may be one.

[0012]

As described above, according to the present invention, the power supply line which reaches the lighting fixture by receiving the control signal from the wall surface operation switch provided with the transmitting portion for converting the operation input into the control signal and transmitting it by the weak radio. The ceiling is equipped with a reception control unit that operates the switching member inserted in the, and because it has a wireless configuration, it does not require a down wiring,
It is possible to significantly reduce the time and effort of electric wiring work, and since the reception control unit does not have to be exposed on the ceiling surface, there is no problem in designing the ceiling surface.

Then, the identification code of the luminaire is added to the control signal transmitted by the transmitter of the wall operation switch, and the reception controller puts the plurality of luminaires under its control and responds according to the identification code in the control signal. If the switching member for the lighting equipment is operated, it is not necessary to provide a reception control unit for each lighting equipment, which is advantageous in terms of the cost of the entire system.
