Vehicle lamp lampshade with anti-fog function and manufacturing method thereof

Abstract

The invention provides a vehicle lamp lampshade with an anti-fog function and a manufacturing method of the vehicle lamp lampshade. A layer of transparent conductive film is tightly attached to the inner surface of a lampshade body; a layer of transparent hydrophobic film is tightly attached to the inner surface of the transparent conductive film; the transparent conductive film is a zinc oxide film doped with 5 percent by weight of aluminum element; the transparent hydrophobic film is a silicon dioxide film; a power interface is fixedly arranged on one side of the lampshade body; the transparent conductive film is connected with a vehicle-mounted power supply through the power supply interface; the vehicle- mounted power supply is used for supplying power to the transparent conductive film; the silicon dioxide transparent hydrophobic film has excellent super-hydrophobic performance, so that fog drops can be effectively prevented from being formed on the inner surface of the lampshade by condensing, and electric contact between the transparent conductive film and the environment in the vehicle lamp can be effectively isolated; the adopted transparent conductive film is a film which is capable of conducting and heating and also has high light transmittance, so that a vehicle lamp is effectively prevented from fogging.

Description

technical field [0001] The invention relates to a car lamp, in particular to a lampshade structure of a car lamp with anti-fog function and a manufacturing method thereof. Background technique [0002] Car lights are one of the important accessories of a car, consisting of lampshades, bulbs, reflectors, etc. With the improvement of modern design, manufacturing and technology, the quality and performance of car lights have been greatly improved. But so far, the problem of fogging of car lights has not been solved. This problem not only affects the life and appearance of car lights, but also significantly reduces the lighting effect of car lights, seriously affecting the safety of driving at night. [0003] The principle of car light fogging is that when the water vapor in the car light forms a temperature difference in the car light, it is formed in the blind area of ​​​​the lamp cover. Fogging of headlights needs to meet three basic conditions: first, the air inside the he...

AI Technical Summary

Problems solved by technology

But so far, the problem of car lights fogging has not been solved. This problem not only affects the life and appearance of car lights, but also significantly reduces the lighting effect of car lights, which seriously affects the safety of driving at night.

3. Optimize the glue used for car lights, enhance the sealing effect of car lights, and prevent water from entering the car lights. This method cannot fundamentally solve the fogging of car lights

4. Seal the lights to make the inside of the lights vacuum. This method is a little difficult to implement

5. Place a desiccant to reduce the water vapor content in the lamp, thereby reducing the possibility of fogging the lamp, but the disadvantage of this method is that the desiccant has a certain service life and needs to be replaced regularly

[0004] Because the fogging of the car lights is mainly formed at the dead corner of the lampshade, however, in the current anti-fogging method of the car lights, there is no way to prevent the fogging of the car lights from the lampshade
