Patent ID: 7965049

Claim:
An electric energy control circuit for a solar power illumination system, wherein said solar power illumination system has at least one solar panel coupled to a charging controller, and said solar panel charges at least one battery via said charging controller, and said electric energy control circuit controls a driving unit to acquire electric energy from said battery and turn on at least one lamp set, comprising: a power detection loop, coupled to said solar panel and said battery, and generating a power generation signal and a remaining capacity signal according to a power generation of said solar panel and a remaining capacity of said battery; and an output control loop, coupled to said power detection loop to receive said power generation signal and said remaining capacity signal and determine the power output to turn on said lamp set, setting a time-setting mode to control a lamp-lighting interval and a power-distribution mode having different power output ratios within a fixed lamp-lighting interval, generating a driving signal under said time-setting mode or said power-distribution mode to actuate said driving unit to convert power from said battery into a driving power to turn on said lamp set.
