Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of dual-light lenses, in particular to an ultra-thin heat sink for dual-light lenses. Background Art

[0002] Dual-beam lenses are mainly used for xenon headlights that share the same light source for low and high beams. There is a shading plate inside the lens, and the high and low beams are achieved by moving the shading plate up and down. Only one xenon bulb is needed to switch between low and high beams. The development and application of this technology has realized the change and use of automobile lighting effects, and improved the convenience and convenience of night driving.

[0003] When the lamp inside the bifocal lens works for a long time, the temperature inside the bifocal lens rises. If the heat inside the bifocal lens is not discharged in time, it is easy to cause damage to the lamp. At present, the heat dissipation effect of the existing bifocal lens is poor, and the heat inside the bifocal lens is still not dissipated in time. Therefore, we need to propose a super-thin radiator for bifocal lenses. Utility Model Content

[0004] The purpose of the utility model is to provide an ultra-thin heat sink for a dual-light lens, which is beneficial to the efficient heat dissipation of a highly integrated LED lens module and prevents damage to the lamp due to untimely heat discharge from the dual-light lens, so as to solve the problems raised in the above-mentioned background technology.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Through the design of the first heat dissipation fin, the second heat dissipation fin and the heat dissipation fan, the first heat dissipation fin is evenly distributed in a radial shape through the ADB area and extends outward, so that a cooling medium channel can be formed between each heat dissipation fin.
