High-efficiency LED double-chip high beam and low beam integrated automobile headlamp cooling system

Abstract

The invention relates to a high-efficiency LED double-chip high beam and low beam integrated automobile headlamp cooling system. The system comprises a radiator. An upper table top and a lower table top are arranged on the upper side and the lower side of a positioning platform of the radiator respectively. Two LED light sources are tightly pressed on the upper table top and the lower table top respectively through two corresponding fixing elastic pieces. An upper reflection cup positioning table and a lower reflection cup positioning table are arranged on the outer side of the upper table top and the outer side of the lower table top respectively. The table top of the upper reflection cup positioning table and the table top of the lower reflection cup positioning table protrude to the outer sides of the table tops of the corresponding positioning platforms. A plurality of parallel fin-shaped cooling fins are distributed on the portions, on the outer side of the upper reflection cup positioning table and the outer side of the lower reflection cup positioning table, of the radiator. Gaps exist between the adjacent cooling fins. The system further comprises a fan. By means of the installation position of the fan, the exhaust direction coincides with the light emitting direction and is opposite to the light emitting direction. The cooling system is good in cooling effect, it is guaranteed that an automobile headlamp is in the safe and stable work environment, and the service life of the automobile headlamp is greatly prolonged.

Description

Technical field [0001] The invention belongs to the technical field of automobile lighting, and particularly relates to a high-efficiency LED dual-chip far and near beam integrated automobile headlight heat dissipation system. Background technique [0002] The interior of the car lights is a closed environment. When the headlights of the car are in an illuminated state, the closed environment where the lights are located will generate a higher temperature due to heat accumulation. This higher temperature is not only easy to produce inside the lights Fog affects the lighting effect, and easily causes the parts in the car headlights to be heated and deformed, and even the parts are melted; in addition, the heat generated by the high temperature does not flow smoothly in the enclosed environment, which will cause the car The shortening of the life of the electronic products inside the headlights seriously affects the normal use of the car headlights. Therefore, it is necessary to co...

Problems solved by technology

[0002] The interior of the car lights is a closed environment. When the headlights of the car are in the lighting state, the closed environment where the lights are located will generate a higher temperature due to heat accumulation. This higher temperature is not only easy to generate Fog affects the lighting effect, and it is easy to cause the parts in the headlights of the car to be heated and deformed, and even the parts are melted; The life of the electronic products inside the headlight is shortened, which seriously affects the normal use of the car headlight, so it is necessary to cool down the closed environment where the car headlight is located

At present, using a radiator to cool down is a common heat dissipation method, but the conventional radiator has a poor heat dissipation effect and needs to be improved urgently
