Description

Technical Field

[0001] The utility model relates to the technical field of automobile headlight modules, in particular to a high-energy-efficiency dual-light module. Background Art

[0002] Traditional car lights are often halogen lamps or xenon lamps, which have obvious defects such as high operating temperature, high power consumption, short service life, and delayed start-up. Therefore, existing car headlights are replaced with LED light sources. When installing the substrate of the LED light source, a metal plate is generally used as the installation platform. The substrate of the low beam light source and the substrate of the high beam light source are respectively installed and fixed on the upper and lower end surfaces of the metal plate. The metal plate can play the role of heat conduction, heat dissipation and support, but it will cause the distance between the lamp beads on the upper and lower substrates to become larger, making the focusing distance of the high and low beams farther, making it difficult to form the best light effect. The closer the distance between the upper and lower lamp beads, the better the light distribution effect will be, and it also increases the volume and cost. Utility Model Content
