LED automobile lamp, manufacturing method of LED automobile lamp and automobile headlamp assembly

Abstract

The invention provides an LED automobile lamp, a manufacturing method of the LED automobile lamp and an automobile headlamp assembly. The LED automobile lamp comprises a lamp body center post, a radiator, LED chips and a strip-shaped circuit board. An installing hole is formed in the radiator, the lower section of the lamp body center post is fixed into the installing hole, and the circuit board is embedded into the side wall of the lamp body center post in the extension direction of the lamp body center post and comprises a body part and a welding part connected with the body part. The LED chips are directly packaged on the side wall of the upper section of the lamp body center post and electrically connected with the welding part. According to the LED automobile lamp and the manufacturing method of the LED automobile lamp, the heat radiation path can be effectively shortened, the heat radiation effect is effectively improved, and due to the fact that the heat radiation performance is improved, the LED chips can be more compactly installed, the overall size of the LED automobile lamp can be reduced, the effect of luminous points can be formed, the requirements for lighting patterns of automobile lighting standards are met, and application and popularization of the LED automobile lamp are improved.

Description

technical field [0001] The invention relates to an automobile lamp, in particular to an LED automobile lamp, a manufacturing method thereof, and an automobile headlight assembly. Background technique [0002] As a new type of light source, LED has the characteristics of energy saving, environmental protection, long life and high reliability. It has been widely used in various fields. For example, in the automotive field, more and more manufacturers use LED as the light source of car lights , when applying LED chips to car lights, because the power of a single LED chip is small, it cannot meet the lighting requirements of car lights. Install the COB light source on the lamp post of the LED car light. Generally, the power of an LED car headlight is about 30 watts. When it works normally, it will generate a lot of heat, and heat dissipation becomes a very acute problem.

Problems solved by technology

Generally, the power of an LED car headlight is about 30 watts. When it works normally, it will generate a lot of heat, and heat dissipation becomes a very acute problem. The heat dissipation method of traditional LED car lights is: LED chip heat conduction To the COB light source bracket, then the COB light source bracket conducts to the lamp post, and then the lamp post conducts to the radiator, which leads to a long heat dissipation path and poor heat dissipation effect

[0003] The heat dissipation effect of traditional LED car lights is poor, which will produce many adverse consequences: poor heat dissipation will generate high temperature accumulation, resulting in damage to the LED light source; Form the effect of luminous point, and often form a larger luminous surface. When LED car lights made of COB light sources are matched with reflectors or bifocal lenses in various car headlight assemblies, they cannot meet industry standards. The light type affects the use effect; and the size of the lamppost and COB light source is large, resulting in the large volume of the LED car light, which cannot be well installed with the headlight assembly of many models, which greatly limits the LED car light.
