Design of intelligent Light Emitting Diode lighting control system
摘要
Abstract
In order to improve the intelligence of Light Emitting Diode(LED) lighting system,the design of controller based on lpc2103 is introduced. The system is composed of the main controller and the unit controller. The pyroelectric infrared sensor detects the signal of human body movements and the photosensitive resistance detects the light signal intensity of environment , both signals are then transmitted to the single chip microcomputer immediately to realize the detection. By using adjustable light chip PT4115,high power LED constant-current driver can be realized. The Pulse Width Modulation (PWM) can keep the light intensity stable. The controller communicates with other devices by the communication module. It has been proved that the proposed circuit system is simple,feasible,sensitive and manageable with low cost.关键词
