AI Technical Summary
Existing automotive front combination lights generate a lot of heat after prolonged use, which can damage the light assembly, affect lighting stability and safety, and increase driving hazards.
A heat dissipation mechanism consisting of a heat sink and heat-conducting fins is installed below the lamp holder, and a vent is provided on the back of the lamp housing. The heat dissipation efficiency is improved by combining the heat-conducting fins and the vent. At the same time, a three-in-one module and a planar grid diffuse reflector are used to uniformly reflect light.
It effectively improves the heat dissipation efficiency of the lamp assembly, extends its service life, ensures uniform and soft lighting, and enhances driving safety and aesthetics.

Abstract
Claims
1. An automotive front combination lamp comprising a lamp housing and a lamp cover, characterized in that: The lamp housing contains a lamp holder, and a heat dissipation mechanism is provided between the lamp holder and the lamp housing. The heat dissipation mechanism includes a heat dissipation block disposed below the lamp holder and heat-conducting fins integrally disposed with the heat dissipation block. The lamp holder includes two parallel mounting bases, each containing a low beam / high beam dual-lamp module and a high beam module. The mounting base also contains daytime running lights, front position lights, and turn signals. The daytime running lights, front position lights, and turn signals are three-in-one modules, consisting of two sets, which are semi-enclosed and disposed on one side of the low beam / high beam dual-lamp module and the high beam module. A planar grid diffuser is provided at the corresponding light source of the three-in-one module.
2. The combination headlamp of claim 1, wherein: The number of low beam and high beam dual-lamp modules is two, arranged vertically in parallel. The number of high beam lamp modules is two, arranged vertically in parallel.
3. The combination headlamp of claim 1, wherein: The heat dissipation mechanism also includes multiple vent holes on the back of the lamp housing, and a semi-circular protective plate is provided on the outside of the vent holes.
4. The combination headlamp of claim 1, wherein: The back of the lamp housing is provided with multiple positioning pins for positioning with the vehicle body during installation.
5. The combination headlamp of claim 1, wherein: The lamp housing has a protrusion inside, the lamp holder has a groove at the bottom corresponding to the protrusion, and the lamp holder has a shock-absorbing pad on the contact surface with the lamp housing.
6. A car front combination lamp according to claim 1, characterized in that: The back of the lamp housing is provided with multiple mounting brackets, and the mounting brackets are provided with mounting holes for fixing the lamp to the vehicle body. The mounting brackets are also provided with reinforcing ribs.
7. The combination headlamp of claim 1, wherein: The edge of the mounting base is provided with a sealing ring groove, and the lampshade is embedded and glued into the sealing ring groove.
8. The automotive combination headlamp of claim 1, wherein: The inner surface of the lampshade is coated with a polyacrylic resin layer, and the outer surface is coated with a PP resin film layer and a polyurethane film layer.
