Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamps, in particular to an eccentric heat dissipation type lamp body structure. Background Art

[0002] Automobile lights usually include a headlight assembly (front lamp assembly), a fog lamp assembly and a taillight assembly. The headlight assembly can usually emit high beam, low beam, turn signal and daytime running light. With the advancement of technology, the headlight bulbs (high and low beam bulbs) in the headlight assembly have halogen headlight bulbs, xenon headlight bulbs and the most advanced LED headlight bulbs. LED headlight bulbs usually include an LED chip for emitting light, a long columnar lamp body for mounting and fixing the LED chip, a heat sink type radiator for heat dissipation and an air-cooling fan for heat dissipation. The above-mentioned LED chip for emitting light, the long columnar lamp body for mounting and fixing the LED chip, the heat sink type radiator for heat dissipation and an air-cooling fan for heat dissipation are all prior art.

[0003] The axial center line of the long columnar lamp body in the current LED headlight bulb usually coincides with the axial center line of the heat sink type radiator. This structural design results in the LED headlight bulb being unable to be installed with special-shaped reflective cups in actual applications, limiting the flexibility of the installation angle of the LED headlight bulb. Therefore, it is necessary to design an eccentric heat dissipation type lamp body structure. Utility Model Content
