摘　　要：提出一种LED路灯控制器的优化设计方案。该方案满足了光控、时控、过充过放控制、防反充和PWM充电控制的要求,并设计出了以PWM控制方式恒流驱动大功率LED灯。经过验证,该LED路灯可通过ATmega16单片机和PAM2842芯片的灵活配置,实现前、后半夜的不同功率供电,系统减小了太阳能电池组件的投资成本,使得路灯的整体设计更加节能,较之传统路灯有较大的市场优势。This paper design an improved street LED lights controller. The system meets the requirement of light control, time control, over charge and over discharge control, anti -charge and PWM charge control, the high-power light is driven by constant current in PWM mode. It has already been validated that the system can be flexibly configured by the ATmegal6 microcontroller and PAM2842 chip to realize different power supply in the first half of the night and the second half. The overall design reduces the investment cost of solar cell module, thus the system will be more energy-efficient and more com- petitive compared with traditional lights.
