Embodiment Construction

[0033] Such as figure 1 Shown is an LED automobile headlight in an embodiment, including: an LED lamp, a substrate 100 , a heat conduction member 200 , a heat dissipation member 300 and a locking member 400 .

[0034] The LED lamp is arranged on the substrate 100, and the substrate 100 is a PCB board (Printed circuit board, printed circuit board). In this embodiment, there can be one LED lamp or multiple LED lamps. Of course, multiple substrates 100 may also be provided on the same substrate 100 . Multiple LED lights can increase the brightness of LED car headlights.

[0035] The heat conduction member 200 is elongated, that is, cylindrical, cuboid, polyhedron elongated, etc. The substrate 100 is fixed on one end of the heat conduction member 200. When the LED automobile headlight is working, the LED lamp on the substrate 100 emits heat, and the heat conduction The member 200 transfers heat from one end provided with the substrate 100 to the other end.

Abstract

A light-emitting diode (LED) automobile headlamp comprises an LED lamp, a heat conduction component and a heat dissipation component, wherein the LED lamp is arranged on a substrate; the heat conduction component is in a long strip shape, the substrate is fixed at one end of the heat conduction component, and the heat conduction component is filled with low-boiling-point liquid; the heat dissipation component comprises a heat dissipation barrel and cooling fins, the heat dissipation barrel is provided with a through hole for accommodating the heat conduction component, and the cooling fins are fixedly arranged around one end of the heat dissipation barrel away from the substrate. According to the LED automobile headlamp, traditional tungsten filaments and high intensity discharge (HID) are replaced with the LED lamp, the low-boiling-point liquid in the heat conduction component is utilized to transmit heat generated by the LED lamp to the rear end in a circulated mode, and the heat dissipation component is utilized to dissipate the heat.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to an LED automobile headlight. Background technique [0002] Traditional car headlights use vacuum tungsten bulbs to emit light, or use gas discharge to emit light HID (High Intensity Discharge, high-intensity gas discharge xenon lamp); or use multiple single LED light-emitting modules. These packaged modules are installed on different heat dissipation structures, and then installed in the lamp holder of the headlight. The gap between the light source module and the heat dissipation structure is filled with thermally conductive silver glue and coated with thermally conductive paste. Corresponding to the above two situations, there is a certain thermal resistance between the light source module and the heat dissipation structure, which leads to a large temperature difference between the light source module and the heat dissipation structure, which cannot completely solve the heat ...
