▎ 摘　　要

NOVELTY - The subassembly has a radiator fixed at a semicircular column body. An LED light source is attached on a horizontal end surface of the radiator through a graphene heat conducting silicone grease. A semicircular outer surface of the radiator is formed as hollow grid shaped structure and made of RLCP (not defined in original specification) graphene fluorine resin material. The radiator is made of one of aluminum material, ceramic material and iron material. A driving power supply is connected with the radiator through a fixed support. USE - Light source subassembly for a road illumination lamp (claimed). ADVANTAGE - The subassembly reduces energy consumption rate and installation volume, and ensures non-destructive replacement, and has structural design, prolonged service life and low light attenuation rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a road illumination lamp. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of a light source subassembly.
