Abstract

The invention discloses an LED (Light Emitting Diode) heat dissipation device and an LED vehicle headlamp comprising same. The LED heat dissipation device comprises a first heat dissipation body and a heat dissipation tube; the first heat dissipation body is connected with an LED circuit substrate; the heat dissipation tube which is connected with the first heat dissipation body is provided with an enclosed inner chamber; the inner inside of the tube wall of the heat dissipation tube is provided with a plurality of axial straight grooves; and one end of the heat dissipation tube is provided with a second heat dissipation body. Refrigerant which is in a fluid state is arranged inside the LED heat dissipation device, so that a rapid heat dissipation loop can be formed and the heat dissipation effect is good. A distance between the first heat dissipation body and the second heat dissipation body can be appropriately increased, so that the LED heat dissipation device can be utilized in light emitting lamp groups of various traditional lamps. A tubular housing of the LED vehicle headlamp and the LED heat dissipation device are formed into a close connection relation by a grooving and center hole drilling way, so that the LED vehicle headlamp is beneficial to heat dissipation of LED lamp beads. Compared with the traditional 100 W halogen vehicle lamp, the LED vehicle headlamp only needs the power consumption of 18 W.

Description

technical field [0001] The present invention relates to a heat dissipation device, more specifically to an LED heat dissipation device and an LED vehicle headlight made of the heat dissipation device. Background technique [0002] In the prior art, LEDs have been widely used as lighting sources. However, there is a big problem in the heat dissipation of the LED light source. In order to achieve better heat dissipation, the LED lamps of major manufacturers are equipped with a huge heat dissipation structure at the LED light source, making LED lamps unable to be used in special application environments such as automotive headlights. Because the light source part of the vehicle headlamp needs to protrude forward for a long distance, the distance between the light source part and the heat dissipation part is relatively large. Therefore, the LED vehicle headlight in the prior art combines the lamp housing and the LED lamp to redesign a set of LED vehicle headlight assembly, whi...
