Aiming　at　various　lighting　energy　supply　circuits　currently　used,　a　improved　Flyback　circuit　is　proposed　applied　in　the　smart　LED　lighting　in　this　paper,　which　can　realize　photovoltaic　power　generation　and　energy　storage,　and　stored　energy　is　inverter　to　the　grid　or　AC　load.　The　proposed　driver　can　realize　multi-form　and　multi-function　utilization　of　energy.　The　circuit　operating　process　is　analyzed　and　the　key　parameters　relation　equations　are　set　up　in　detail.　The　design　circuit　uses　18V　photovoltaic　panel　as　input,　24V　6AH　lead-acid　battery　as　storage　part,　three　1W　350mA　LED　lamps　in　series　as　LED　lamp　group,　and　50　ohms　AC　load　as　DC-AC　inverter　load.　The　simulation　software　PSIM　is　carried　out　to　verify　the　feasibility　of　the　improved　circuit　design　and　analysis.　©　2019　IEEE.
