Description

Lamp body structure for automobile headlamp and automobile headlamp

technical field

The utility model relates to the field of automobile lighting, in particular to a lamp body structure used for automobile headlights and the automobile headlights.

Background technique

As a new type of green light source product, LED has excellent characteristics such as small size, low energy consumption, high brightness, long life and environmental protection. It can be widely used in many lighting fields, and is also suitable for automotive lighting. However, the heat dissipation method of the existing LED as the light source of the car headlight adopts the LED light-emitting module to connect the radiator through the lamp body, which needs to go through multiple links and multiple levels of heat conduction or passive heat dissipation, so the high-wattage cannot be effectively cooled. The heat generated by several LED light sources is smoothly conducted, and the heat dissipation effect is poor, so that the heat generated by itself will burn itself out and burn out. In addition, the temperature of the position of the car structure where the luminous body is located is high, which greatly reduces the service life of the car lights. The light output efficiency is low and the performance is unstable. At the same time, frequent replacement of LED illuminants increases the driver's car cost.

Therefore, it is an urgent problem to be solved that the heat of the luminous body cannot be conducted out in time due to the imperfect structural design of the existing LED car light body, resulting in light decay, low brightness, and even short life of the luminous body when it burns out.

detailed description

It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1, the first embodiment of the utility model proposes a lamp body structure for automobile headlights, including a fan 10 arranged at the tail of the lamp body for dissipating heat from the illuminant, and a fan 10 connected with the fan 10. On the lamp post 20 on which the luminous body 30 is installed, the lamp post 20 is provided with a ventilation channel 21 communicating with the ventilation opening of the fan 10 for dissipating heat from the lamp body and the luminous body. The lamp body structure for automobile headlights proposed in this embodiment is provided with a ventilation channel for dissipating heat from the illuminant 30 on the lamp post 20, so that the lamp body can be blown by the ventilation channel while there is a fan.
