STREAM LIGHTING TYPE ILLUMINATION SYSTEM AND CONTROL DEVICE USED FOR SAME
Document Type and Number:
Japanese Patent JP2007317483
Kind Code:
A
Abstract:
To execute a series of smooth stream lighting by a plurality of control devices for respectively controlling the stream lighting of a plurality of light sources, in a stream lighting type illumination system and a control device used for the system.
This stream lighting type illumination system 1 is provided with: LEDs 31-3N; a control device 2ifor controlling the stream lighting of the LEDs 31-3M; and a control device 2i+1for controlling the stream lighting of LEDs 3M+1-3N. A transmission part 6i of the control device 2itransmits an annunciation signal for annunciating lighting timing for controlling the series of stream lighting to the rear-stage control device 2i+1in the stream lighting sequence. A reception part 4i+1of the control device 2i+1receives the annunciation signal, and a microcomputer 5i+1sequentially transmits control signals for lighting control to the LEDs 3M+1-3Nby using the annunciation signal as a trigger. Thus, the series of smooth stream lighting by the control devices 2iand 2i+1for respectively controlling the stream lighting of the plurality of LEDs 31-3Nis enabled.
