This article uses the photo resistance collecting light intensity signal, uses the F05P and the J04V wireless transceiver modules for communication, uses the low power consumption MSP430F169 microprocessor for controlling and data processing, uses BP2808-constant current controlling chip which can convert the PWM signal outputed by MCU to the drive current controlled by the PWM duty cycle , coordinated the PID closed-loop control algorithm to design one kind of new energy-efficient light compensation light-controlling system. This system can make the best of daylight for compensation for self-luminous to make the sum of LED’s brightness and the brightness of natural light keep stably in the setting brightness, so as to achieve the purpose of energy saving.
