Problems solved by technology

When the LED car headlight is installed, the LED light source is installed towards the left and right sides, and the light is reflected by the lampshade (the left light source becomes the right light after being reflected by the lampshade, and the right light source becomes the left light after being reflected by the lampshade) ), so there is an area with weak light on the upper and lower sides, and there may even be a blind area of ​​illumination, which cannot achieve the 360-degree coverage effect of traditional halogen lamps or xenon lamps. The existing technology cannot take into account both light patterns and heat transfer

Abstract

The invention relates to a heat conduction type LED lamp body with a metal body clamping the side edges for a vehicle lamp, the LED vehicle body and a heat dissipation method of the LED vehicle lamp and belongs to the field of LED vehicle lamp heat dissipation. The LED lamp body comprises LED light sources and circuit boards, the LED light sources are mounted on the circuit boards, and the LED lamp body further comprises the metal body for conducting heat from the front circuit boards to a rear radiator. The metal body is in a long strip shape, the surface of the metal body is provided with a clamping groove extending in the length direction, and the width of the clamping groove corresponds to the thicknesses of the circuit boards so as to be used for placing-in of the circuit boards. After the outer wall of the metal body is pressed, the clamping groove is narrowed, so that the side edges of the circuit boards are clamped. The LED vehicle body adopts the heat conduction type LED lamp body with the metal body clamping the side edges for the vehicle lamp. According to the heat conduction type LED lamp body with the metal body clamping the side edges for the vehicle lamp, the LED vehicle body and the heat dissipation method of the LED vehicle lamp, the structure is simple, the metal body for heat transfer is arranged on the side, with the low light utilization rate, of the vehicle lamp, the size of a heat transfer component does not need to be reduced, the heat transfer effect is ensured, and the good light shape is also ensured; and meanwhile the metal body has the clamping function.

Description

technical field [0001] The invention relates to heat dissipation technology of LED vehicle lights, in particular to metal bodies used for vehicle lights to clamp side heat-conducting LED lamp bodies, LED vehicle lights using the LED lamp body, and heat dissipation method of the LED vehicle lights. Background technique [0002] LED car lights refer to car lights that use LEDs (light-emitting diodes) as light sources. Because LED has the characteristics of high brightness, rich color variety, low power consumption, and long life, LED is widely used in the automotive field. [0003] However, with the wide application of LED car lights and the need for lighting intensity, people have put forward higher requirements for their power. The increase in power makes the heat dissipation enhancement of LED car lights a factor that must be considered to ensure the quality of its products. If the heat cannot be effectively conducted, it will seriously affect the service life of LED light...
