LIGHTING CONTROL CIRCUIT OF SENSOR LAMP

摘要

PURPOSE: A lighting control circuit is provided to be capable of controlling the lighting of a sensor lamp without an abnormal operation by judging an entrance of a person and whether or not of noise using an artificial intelligence. CONSTITUTION: A superconduction-type body sensor senses an access of the body through thermal tracking. A high frequency noise eliminating part(32) eliminates an unnecessary component included in a sense signal of the body sensor. The first amplification part(34) inversely amplifies an output of the high frequency noise eliminating part(32). The second amplification part(38) amplifies an output signal of the first amplification part using a reference voltage of a reference voltage generating part. A microcomputer outputs a control signal for driving a bulb according to control values of a CDS sensibility adjusting part and a set timing adjusting part when a sense signal is received from the second amplification part. An output part receives an output of the microcomputer through a photocoupler and switches a power for controlling the bulb.
