PURPOSE: there is embedded solar battery, which to provide, for a kind of LED device prevents LED and reflecting plate of deterioration by cooling heat sink, passes through blower fan. ;CONSTITUTION: a kind of LED component, including metal substrate (11), solar battery (3), blower fan (6). A kind of LED (1) is mounted on metallic substrates. LED conversion lights are equipped with around solar battery from LED to electric energy. The air blower is driven and electric energy is from solar battery. Blower is cooling, and heat is from LED. Heat removed is discharged from air blower to LED device in heat extraction path (13). ;The 2010 of copyright KIPO submissions
