CONTROL METHOD OF LED ILLUMINATION LAMP SYSTEM, LED ILLUMINATION LAMP CONTROLLED BY THIS METHOD, AND LED ILLUMINATION LAMP CONTROLLER CONTROLLING ILLUMINATION LAMP

摘要

PROBLEM TO BE SOLVED: To provide an LED illumination lamp in which running cost can be reduced furthermore by providing a function to adjust the brightness of a plurality of LED illumination lamps by remote control and risk due to overheat can be prevented, and to provide a control method of an LED illumination lamp, and a controller of an LED illumination lamp.;SOLUTION: A plurality of LED illumination lamps L11-L2n are connected via an LED illumination lamp controller 1 and an AC power supply line. The LED illumination lamp controller transmits address information and illuminance information to each LED illumination lamp via the AC power supply line, and the LED illumination lamp adjusts illuminance, and the like, individually. Consequently, illumination power can be saved effectively. Furthermore, the LED illumination lamp is provided with a function to perform turn-off control when any one of the light-emitting diodes thereof is open-circuited, thus preventing risk due to overheat.;COPYRIGHT: (C)2012,JPO&INPIT
