Embodiment 1
[0021] Such as figure 1 As shown, a heat dissipation structure integrating a reflector and an air duct includes a reflector body 1 and an air duct assembly. The air duct assembly is an air duct structure required for LED heat dissipation for air volume delivery. The required reflector structure provides reflection for the LED light source. The air duct assembly includes a plurality of splitter plates 3 arranged on the reflector body 1. An air guide groove 4 is formed between two adjacent splitter plates 3. The air guide groove 4 One end is the air inlet end 6, the other end of the air guide groove 4 is the air outlet end 7, the splitter plate 3 is arc-shaped as a whole, and the reflector body 1 is provided with a hollow cavity 2 for installing LEDs corresponding to the air outlet end 7, and the air outlet A plurality of splitter fins 5 are arranged at the end 7, and the wind enters the corresponding air guide groove 4 from the air inlet end 6, and the splitter plate 3 can play...

The invention relates to the field of automobile lighting, and particularly relates to a reflector and air duct integrated heat dissipation structure. The reflector and air duct integrated heat dissipation structure comprises a reflector body and an air duct assembly, the air duct assembly comprises a plurality of flow dividing plates arranged on the reflector body, an air guide groove is formed between every two adjacent flow dividing plates, one end of each air guide groove is an air inlet end, the other end of each air guide groove is an air outlet end, a hollow cavity used for installing an LED is formed in the position, corresponding to each air outlet end, of the reflector body, and a plurality of flow dividing fins are arranged at the air outlet ends. According to the reflector and air duct integrated heat dissipation structure, the internal structure layout space of a front combination lamp can be saved, the production cost is reduced, and the heat dissipation effect is good.
Description
technical field [0001] The invention relates to the field of automobile lighting, in particular to a heat dissipation structure integrating a reflector and an air duct. Background technique [0002] As an important part of the car, the front combination lamp is mainly used for night lighting to provide drivers with good lighting and understand road traffic conditions, thereby reducing the probability of traffic accidents. The general front combination lamp mainly has the following functions: high beam function; low beam function; turn signal function, and some also have daytime running light function. With the development of car lighting technology to the present, the mainstream light source of far and low beams basically relies on LEDs to emit light, and LED lights also generate a lot of heat when they work. When the temperature is too high, it will affect the life of the lamp beads, and seriously cause The lamp beads are damaged and fail, and at the same time, the structu...
