[Prior art]
When installing multiple temporary lighting devices at hotels, wedding halls, banquet halls, exhibition halls, event halls, etc., usually provide a dimming device that performs comprehensive dimming control for lighting control. In addition, a cable for sending a power source and a control signal from this light control device to each lighting device is laid and controlled. Even if each dimming circuit has a built-in dimming circuit and no dimming device is required, it is necessary to lay a power cable, a control signal cable, and the like.
As a conventional technique for remote control of such illumination, for example, a method and apparatus for controlling a lighting device composed of multi-colored LEDs having an addressable controller by wire is proposed (for example, Patent Document 1). reference.).
In addition, a drive device has been proposed in which the irradiation direction of the illumination device is switched by wired remote operation, and is changed and corrected by wireless remote operation (see Patent Document 2).

However, in such a control method using a cable, since the cable is laid, it takes time and there is a risk of deteriorating the beauty of the venue where the lighting is set up. In addition, there is a problem that a lighting device cannot be provided at a place where a cable cannot be laid even if it is necessary for production. In addition, the conventional illumination has a form in which a color filter is attached in front of a white light source and the transmitted light of the filter is used. Therefore, to change the color, the color filter must be replaced. It was hanging.
As a lighting control method that does not use wired communication, a wireless pager receiver is placed beside the lighting device, and the wireless pager receiver is connected to a computer processor or electronic circuit provided in the lighting device to switch the lighting device on and off. A control system that switches brightness and the like has been proposed (see Patent Document 3). However, this method makes the apparatus large and large, and is not suitable for lighting in a venue.

The CPU 22 analyzes digital data or analog data input from the general-purpose light control table 25 and digital data input from the external computer 26, converts the data into light control data that can be recognized by the LED lighting device 1, and a wireless transmitter. Send to 21.
The data format of the communication data of the wireless transmitter 21 conforms to, for example, DMX512 of United States Institute for Theater Technology, Inc. (American Theater Technology Association).
In this format, the data array is, for example, a 4-byte configuration of R, G, B, and W per LED lighting device, and a data group of 512 bytes for a maximum of 128 LED lighting devices 1 is used as a wireless transmitter. 21 is transmitted.
[0019]
Here, for example, when setting the first LED lighting device 1-1 to 100% luminance of red light, the first byte of data is set to 255, the second byte, the third byte, and the fourth byte are set to 0, respectively. Set. Also, if you want to set the third LED lighting device 1-3 to yellow light with 50% luminance, the 9th byte of data is 127, the 10th byte is 127, the 11th byte and the 12th byte are 0 respectively.

Further, the D / A converter 43 converts the emission luminance data of the blue LED into an analog voltage, and applies a voltage from the current driving circuit 47 to the red LED group 33 to control the emission luminance of the blue LED. The D / A converter 44 converts the light emission luminance data of the white LED into an analog voltage, applies a voltage from the current drive circuit 48 to the white LED group 31, and controls the light emission luminance of the white LED.
In FIG. 2, the current drive circuits 45 to 48 apply light potential to the anodes of the LED groups 31 to 34 to control light emission, but it is also possible to control light emission by switching the cathode side ground.
[0025]
