Heat radiating device for LED vehicle lamp

Abstract

The invention provides a radiator for a LED car lamp; the LED car lamp comprises a car lamp group, a heat dissipating module, a plurality of LEDs and a reflection unit; wherein, the heat dissipating module is coated with an insulation circuit to enable the insulation circuit and the heat dissipating module to realize the purpose of heat-electricity separation; the LEDs are electrically connected with the insulation circuit of the heat dissipating module; the body base of the LEDs is provided with a metal heat-conducting plate used for conducting the heat energy generated by the LEDs to the heat dissipating module; the reflection unit is arranged in the car lamp group; based on the heat dissipating module, the cold air or cooling fluid are used as the heat dissipating medium to dissipate the heat energy generated by the LEDs; furthermore, the light output of the LEDs of the LED car lamp is not reduced due to the overheating; the damage of the LED car lamp is prevented; the service life of the LED car lamp is prolonged.

Description

technical field [0001] The invention relates to a heat dissipation device for an LED vehicle lamp. Background technique [0002] At present, the illuminants used in the lights of vehicles can be mainly divided into three types: halogen bulbs, xenon bulbs and LEDs. In particular, the LED has reached the technical level of high brightness in terms of current technology. However, when the LEDs are used in vehicle lights, multiple LEDs must still be used to provide sufficient brightness, which meets the specifications of relevant regulations on vehicle lamps. However, the luminous efficiency of the LED itself only accounts for about 20% of the input energy, and about 80% of the input energy is dissipated as heat, so higher heat energy will be generated in power consumption. When a plurality of LEDs are applied to a car light, high heat energy will be generated, and the heat energy generated by the LEDs cannot be eliminated by other means, causing the LEDs to reduce the light o...
