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...

Examples

Embodiment Construction

[0018] see figure 1 , the car lights generally include a rear cover, a lampshade 4, a reflector 2 and a bulb 3, the rear cover (not shown in the figure) and the lampshade 4 form a closed cavity, and the reflector 2 and the bulb 3 are sealed in the cavity, The light emitted by the bulb 3 is reflected to the lampshade 4 by the reflector 2 .

[0019] see you again figure 2 The lampshade 4 is composed of a lampshade body 6, a power interface 5, a transparent conductive film 7 and a transparent hydrophobic film 8. The outermost layer of the lampshade 4 is the lampshade body 6, and a layer of transparent conductive film 7 is closely attached to the inner surface of the lampshade body 6. , on the inner surface of the transparent conductive film 7, a layer of transparent hydrophobic film 8 is tightly adhered. A power supply interface 5 is fixed on one side of the lampshade body 6, and the transparent conductive film 7 is connected with the vehicle-mounted power supply through the p...
