Problems solved by technology

[0004] The traditional LED heat dissipation method is to directly install a heat dissipation device on the LED. This method not only has a relatively low heat dissipation efficiency, but also shortens the service life of the LED headlight, increases the frequency of replacing the headlight, and greatly increases the maintenance cost.
Although there are currently some LED headlights that use circulating liquid cooling, they are connected to a water-cooled radiator, which is relatively large in size and mass, and costs a lot. It takes up a part of the space of the car and increases the weight of the car. Car Design Adds Difficulty

Abstract

The invention discloses a self-circulation liquid-cooled LED automotive headlamp. The self-circulation liquid-cooled LED automotive headlamp comprises a cylindrical lamp body. A lamp cover is arranged at the front end of the lamp body. At least one radiator is arranged at the rear end of the lamp body. A vacuum cavity is formed inside the lamp body. A layer of coolants are arranged inside the cavity of the lamp body. A plurality of LED lamp beads are evenly distributed on the lamp body along the cylindrical surface of the lamp body. The lamp body is provided with an adjusting plate used for adjusting light ray focuses of the LED lamp beads. According to the self-circulation liquid-cooled LED automotive headlamp, the self-circulation liquid-cooled heat dissipation technology is adopted, the lamp body and the radiators are integrated, the size is small, the structure is simple, the cost is low, the heat dissipation efficiency of the lamp body is improved greatly, the occupied space is reduced, heat dissipation of an LED automotive headlamp in an airtight working environment is successfully realized, reliability and service life of the LED automotive headlamp are guaranteed, the service life of the LED automotive headlamp is prolonged by 10-30 times compared with that of a traditional lamp, and it becomes possible that the LED automotive headlamp can be used for whole life long without being replaced.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a self-circulating liquid-cooled LED automobile headlamp. [0002] Background technique [0003] Today, LED technology has been widely used in various vehicles. For example, most motor headlights have also adopted LED technology. Although under the same brightness conditions, LED lamp beads are more energy-efficient than traditional lamp beads, but because LED lamp beads are highly concentrated in a closed working environment such as a lampshade, the heat generated by them is also highly concentrated. How to dissipate heat is an urgent problem. The problem. [0004] The traditional LED heat dissipation method is to directly install a heat dissipation device on the LED. This method not only has a relatively low heat dissipation efficiency, but also shortens the service life of the LED headlight, increases the frequency of replacing the headlight, and greatly increases the m...
