Anti-fogging and frost-prevention device of automobile lamp

Abstract

The invention relates to the technical field of automobile lamps, and discloses an anti-fogging and frost-prevention device of an automobile lamp. The anti-fogging and frost-prevention device comprises an original lamp face mask, an additional face mask, a sealing gasket, an outer decoration ring, a screw, a heating wire and a drying agent; and at least one layer of additional face mask is arranged outside the original lamp face mask, a gap between the additional face mask and the original lamp face mask is 5 mm to 10 mm, the gap can be adjusted according to needs, and the drying agent and the heating wire are arranged in the gap. According to the device, a gas or vacuum layer is formed between the additional face mask and the original lamp face mask, the drying agent and the heating wire are arranged in the gap, left moisture is further removed, as the gas or vacuum layer is a poor conductor of heat, coagulating fogging of a lampshade cannot be generated by sudden temperature falling under extreme climate, and the climate adaptability of the automobile lighting lamp is improved. The anti-fogging and frost-prevention device has the beneficial effects of being simple in structure, low in cost and high in practicability, and the anti-fogging and frost-prevention device can be used for lamps such as halide torches, HIDs and LEDs.

Description

Technical field [0001] The invention relates to the technical field of automobile lamps, in particular to an anti-fog and anti-frost device for automobile lamps. Background technique [0002] In extreme climates, during the lighting and extinguishing process of the external lamps of a car, due to the temperature difference and humidity difference between the inside and outside of the lamps, it is easy to produce condensation inside the transparent mask of the lamps, and the appearance is frosting or fogging. Fogging inside the car lamps will not only affect the appearance of the lamps, but also affect the lighting effects of the external lamps and the driver's driving vision, and affect the safety of driving. At present, the way to deal with the fogging of automobile lamps is usually to install a separate device inside the lamp to heat the inside of the lamp to defog, but because it is difficult to exhaust the moisture inside the lamp, it takes a long time and defogging. The eff...

Fogging inside the car lamps will not only affect the appearance of the lamps, but the most important thing is to affect the lighting effect of the external lamps and the driving vision of the driver, affecting the safety of driving

At present, the way to deal with the fogging of automobile lamps is usually to install a separate device inside the lamp to heat the inside of the lamp to defog, but because it is difficult to discharge the moisture inside the lamp, it takes a long time to defog and The effect is not good, and when the lamp is turned off, due to the decrease of the internal temperature of the lamp, the phenomenon of fogging will appear again
