LED PHOTO-ELECTRIC SOURCE ASSEMBLY AND LED ROAD LAMP

摘要

An LED photo-electric source assembly includes a radiator, a radiating fan, a driving circuit board subassembly, an LED light source component, an upper cover of a power supply box, a lower cover of the power supply box and a waterproof bolt component. The radiator comprises a bottom plate, on top of which a radiating part is provided. A space area of the radiating part contains a dust-proof, water-proof fan. An LED road lamp further includes an LED photo-electric source assembly, an installing board and a housing assembly of a traditional road lamp for containing light source. A light outlet arranged on the installing board adapts in size and shape to an opening arranged at the bottom of the housing assembly. The LED photo-electric source assembly is fixedly connected to the installing board and emits light. The installing board is fixedly connected with the housing assembly through a clamping fixture.
