Description

Technical Field

[0001] The utility model relates to the technical field of LED automobile lamps, in particular to a fast heat dissipation type heat pipe heat dissipation type LED automobile lamp. Background Art

[0002] An LED lamp is an electroluminescent semiconductor material chip, which is solidified onto a bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire, and sealed with epoxy resin on all sides. LED car lights are one of the important accessories of a car, playing an important role in lighting and indicating lights.

[0003] The utility model patent with announcement number CN212377918U discloses a fast-heating heat pipe-heating LED automotive lamp. This patent transfers heat to the heat pipe radiator through the lampshade. The perforation is used to pass the wiring harness connected to the LED light source, and the external thread is used for fixing the lamp. The high-temperature silicone sheet improves the heat conduction efficiency between the lampshade and the heat pipe, and the heat dissipation effect is good. However, during the implementation of this patent, the lampshade itself has poor heat transfer effect. The heat inside the lampshade is difficult to transfer quickly to the heat pipe surface, making it difficult for the heat inside the lampshade to dissipate quickly, which is not conducive to improving the heat dissipation efficiency. Therefore, the research and development of new fast-heating heat pipe-heating LED automotive lamps has attracted the attention of more and more researchers. Utility Model Content
