▎ 摘　　要

NOVELTY - The assembly has lamp holder (3) penetrated with mounting hole. A laser light source (2) is clamped in mounting hole. A radiator (1) is provided with multiple location columns and multiple predetermined position columns. The lamp holder is provided with locating hole matched with location column and predetermined position hole matched with predetermined position column. The lamp holder is fixedly set on radiator through multiple first bolts. The bottom surface of laser light source and radiator contact multiple location columns and multiple predetermined column are distributed around circumferential direction of laser light source. Multiple predetermined columns are located at periphery of multiple location columns. A light source electric plate (4) is set below radiator. The pin of laser light source passes through connecting hole and is connected with light source electric plate. A reflector (5) is set on radiator. The reflector is located above laser light source. USE - Mounting assembly of light source is useful for vehicle lamp module (claimed). ADVANTAGE - The mounting assembly of light source has simple and reliable structure, smart design, reduces the mounting difficulty, and improves the assembling efficiency. The positioning precision of the lamp holder is improved. The material of the radiating main body and lamp holder are made of aluminum, copper or heat conducting graphene to ensure the structural strength and improving the radiator effect. The mounting structure of the light source electric plate and the reflector is simple and firm, and the locating precision is high. The relative position precision of laser light source and reflector are high, the mounting assembly is stable and reliable, and light source utilization rate is high, by setting the locating structure composed of a location column and a predetermined position column on the radiator. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the mounting assembly of light source. Radiator (1) Laser light source (2) Lamp holder (3) Light source electric plate (4) Reflector (5)
