摘要

The control system for Solar powered LED Road traffic sign was designed. This system consists of 4 parts: energy transformation unit, energy charging unit, energy discharging unit and control unit. It has various functions such as dayight transition, light-time control and battery protection. This system is powered by both solar and battery. Test results showed 94% energy charging efficiency and 99.6% discharge efficiency (8.8mW standby power).
