Abstract

The invention relates to the technical field of automobile accessories and in particular to a mounting plate of an automobile lamp. The mounting plate provided by the invention is used for connecting a lamp post and a reflective cup. The mounting plate comprises a circuit board and a heat-dissipating plate close to the lamp post on the circuit board. A plurality of air outlet holes through the heat-dissipating plate are formed in the heat-dissipating plate. According to the mounting plate of the automobile lamp and a manufacturing process thereof, the product is reasonable in structural design and high in heat-dissipating efficiency, and meanwhile, the heat-dissipating plate is pre-treated when the mounting plate is processed and manufactured, so that the heat-dissipating efficiency and the corrosion resistance of the mounting plate are improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a mounting plate for an auto lamp. Background technique [0002] Automobile headlights are tools for vehicle lighting, which play an important role in the process of safe driving of vehicles.
