Projection-type high-power LED automobile dipped headlight and manufacturing technique thereof

Abstract

The invention relates to a projection-type high-power LED automobile dipped headlight which has the technical proposal that the lower part of a dipped headlight body (10) is provided with a circuit control module (9), the middle part thereof is provided with a light distribution forming board (5) and the top part thereof is provided with an optical lens (1), wherein, the optical lens (1) is fixed at the upper part of a lens mount (2), the light distribution forming board (5) is arranged at the lower end of the lens mount (2), a main reflection plane (4) is arranged at the bottom surface of the light distribution forming board (5), an auxiliary reflection plane (3) is positioned at the upper surface of the light distribution forming board, and an LED light source (6) is arranged above an auxiliary radiator (7). A method for manufacturing the projection-type high-power LED automobile dipped headlight comprises: 1) selection of the LED light source; 2) the optical lens preparation; 3) the light distribution forming board, the main reflection plane and the auxiliary reflection plane preparation; 4) the lens mount preparation; 5) the auxiliary radiator preparation; and 6) assembly. By adopting the invention, the light emitted by the LED light source is processed by secondary light distribution, so that the two problems of heat dissipation and light distribution can be solved. The LED automobile dipped headlight has high luminous efficiency, uniform and soft light source and prolonged service life by 4-5 times, thus being more beneficial for the road ahead lighting and high speed driving.

Description

technical field [0001] The invention relates to the field of automobile semiconductor lighting, in particular to a projected high-power LED automobile low beam lamp. technical background [0002] At present, automotive lighting mostly uses halogen tungsten lamps or HID light sources. LED lighting has become the best light source to replace traditional light sources in the 21st century due to its high brightness, low power consumption, long service life, and good color rendering. LEDs have been widely used in automotive signal lights in recent years. As for automotive lighting, it is still in the development stage of technology verification and concept car display in the world. At present, high-end configurations in the United States and Japan are beginning to be tested, but the design method of multi-module and multi-lens groups is adopted, which makes Its structure is very complex and the cost is very high; domestic LED automotive lighting is still in the stage of technic...

Problems solved by technology

As for automotive lighting, it is still in the development stage of technology verification and concept car display in the world. At present, high-end configurations in the United States and Japan are beginning to be tested, but the design method of multi-module and multi-lens groups is adopted, which makes Its structure is very complex and the cost is very high; domestic LED automotive lighting is still in the stage of technical research and has not yet achieved industrialization

The main difficulty lies in the lack of breakthroughs in key technologies such as high-power LED heat dissipation, light distribution, and power management.
