2. Description of the Related Art Conventionally, when performing lighting in a banquet hall or the like, a light control console is used to control the light control panel with a high-speed digital signal (DMX signal) called a dedicated DMX 512, and the light control panel is used. Power lines were routed for each load by the number of loads. Therefore, if the load is large, the number of power lines becomes enormous, and the first problem is that the construction is also difficult.

As a method of producing an effect in a relatively small space with a simple construction, Japanese Patent Application No. Hei.
No. 4390, which uses a dedicated controller to control the control block installed in the appliance with only signal lines and changes the light source in the appliance in a predetermined order to enhance the effect. is there. However, in this method, the change is constant and complicated effects cannot be performed.
There is a second problem that the light control console cannot be connected to the above-mentioned light control console and the usage is limited.

As means for solving the second problem,
Japanese Patent Application No. 9-41172 filed by the inventor of the present invention discloses a method of interpreting a DMX512 signal of a dimmer and performing DM processing.
An interface (hereinafter, referred to as an I / F unit) for converting into a digital signal having a lower transmission speed than the X512 signal is provided. With this configuration, both the dedicated signal from the dedicated controller and the DMX512 signal can be connected, and the use range has been widened.

[0005]

However, in the present system (Japanese Patent Application No. 9-41172), the following third problem occurs.

Since the output from the I / F unit is not fixed until the input signal is fixed when the power is turned on, the operation of the light source is not known, and the light source is repeatedly turned off and turned on or used suddenly. This may be an operation that gives anxiety or discomfort to the person, which is not a very favorable state. When sudden lighting occurs, particularly in a large-scale place, a large current flows at the moment of lighting, and a breaker may fall.

SUMMARY OF THE INVENTION The present invention has been made in view of all of the above problems, and has as its object to provide an illuminating device that includes an I / F unit and does not give a user anxiety or discomfort when the power is turned on. It is to provide.

/ F unit, 4 is a lighting fixture, 5 is a control unit (hereinafter, referred to as a control block), and 6 is a light source. The dedicated controller 1 sends a relatively low-speed digital signal (dedicated signal), controls the control block 5 with the dedicated signal, and controls the light source 6.
Is changed by predetermined control. The light control console 2 transmits a high-speed digital signal of the DMX512 (DMX512 signal). The high-speed digital signal is interpreted by the I / F unit 3 and transmitted to the control block 5. The DMX512 signal is
Only necessary channels are interpreted from predetermined channels set by the I / F unit 3, and other channels are set to be ignored.
