Embodiment 1

[0035] Such as Figure 1-Figure 7 As shown, the LED light-emitting system provided by the embodiment of the present invention includes: a light-emitting module 10, a bracket 20, an air supply device 30 and a heat dissipation air duct 40, and the air supply device 30, the heat dissipation air duct 40 and the light-emitting module 10 are all installed on the support 20 Above, the air outlet of the air supply device 30 communicates with the air inlet of the heat dissipation air duct 40 , and the air outlet of the heat dissipation air duct 40 faces the light emitting module 10 .

[0036] The LED light-emitting system of the embodiment of the present invention is applied to a car light. During operation, the light-emitting module 10 emits light and generates heat, and the heat generated by the light-emitting module 10 is dissipated into the surrounding air. The heat dissipation air duct 40 guides the wind generated by the air supply device 30 to the light emitting module 10, thereb...

Embodiment 2

[0052] Embodiment 2 of the present invention provides a vehicle lamp, which includes a housing, and the LED lighting system provided in Embodiment 1 above is installed in the housing.

[0053] Since the LED lighting system provided by the first embodiment above is provided in the vehicle lamp, the advantages of the vehicle lamp and the above-mentioned LED lighting system over the prior art are the same, and will not be repeated here. In addition, due to the good heat dissipation effect of the lighting system, strong working stability, and long service life, the number of replacements is small, thereby reducing the number of maintenance times for the lights in the later stage, thereby avoiding the error of the light irradiation angle caused by frequent replacements.

[0054] At the same time, since the LED lighting system is equipped with an air supply device and a cooling air duct, the use area of ​​the heat sink in the LED lighting system can be reduced while achieving the sam...

Abstract

The invention relates to the technical field of vehicle lamps and provides an LED light-emitting system and a vehicle lamp so as to solve the problem that the heat dissipating effect of vehicle lampsin the prior art is poor. The LED light-emitting system comprises a light-emitting module, a support, an air supplying device and a heat dissipating air channel, the air feeding device, the heat dissipating air channel and the light-emitting module are all mounted on the support, and an air outlet of the air supplying device communicates with an air inlet of the heat dissipating air channel. An air outlet of the heat dissipating air channel faces the light-emitting module. The LED light-emitting system is applied to the vehicle lamp, the light-emitting module is cooled through air cooling, theheat dissipating effect is good, and thus the service life of the LED light-emitting system is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle lamps, in particular to an LED lighting system and a vehicle lamp. Background technique [0002] Because LED (Light Emitting Diode, light-emitting diode) has the characteristics of high brightness, rich colors, low power consumption, and long life, LEDs are widely used as light sources in current car lights. LEDs generate high heat when they work, and must be used The heat dissipation system dissipates heat for it. [0003] In current automobile lamps, a heat sink is usually used to dissipate heat for the LED light source. Specifically, the aluminum substrate of the LED light source is connected to the heat sink, and the heat sink is installed on the reflector. The heat sink includes heat sinks, the heat generated by the aluminum substrate is transferred to the heat sinks, and the heat dissipation area is increased through the heat sinks to improve the heat dissipation effect. If you want to imp...
