LED PHOTO-ELECTRIC SOURCE ASSEMBLY AND LED ROAD LAMP IMPROVED FROM TRADITIONAL ROAD LAMP

摘要

An LED photo-electric source assembly including a radiator (1), a radiating fan (2), a driving circuit board subassembly (3), an LED light source component (4), an upper cover (31) of a power supply box, a lower cover (32) of the power supply box and a waterproof bolt component (34) is provided. The radiator (1) comprises a bottom plate (11), on the top face of which a radiating part (12) is provided. In the central area of the upper part of radiating part (12), a space area is provided for containing the radiating fan (2) i.e. dust-proof and water-proof fan. An LED road lamp improved from traditional road lamp including an LED photo-electric source assembly (600), an installing board (700) and a housing assembly (100) of a traditional road lamp for containing light source is provided. A light outlet (701) arranged on the installing board (700) adapts in size and shape to an opening arranged at the bottom of the housing assembly (100). The LED photo-electric source assembly (600) is fixedly connected to the installing board (700) and emits light through the light outlet (701) and the installing board (700) is fixedly connected with the housing assembly (100) through a clamping fixture. This LED photo-electric source assembly can be widely applied to the field of LED illumination.
