Description

Car light defogging system, car light and vehicle

Technical Field

The utility model relates to a vehicle lamp, in particular to a defogging system for the vehicle lamp. In addition, still relate to a car light and vehicle that contains this car light defogging system.

Background

The fogging of the car lamp not only affects the lighting effect, but also threatens the service life of the bulb and the safety of the circuit in the lamp. Moreover, long-term condensation of water vapor on the surfaces of the reflector and the lens of the automobile lamp can lead to a series of consequences such as corrosion of automobile lamp materials, accelerated aging deformation, damage of optical regulation and control effects and the like.

At present, a ventilation component is designed on a vehicle lamp, and air in the vehicle lamp is exchanged with air outside the vehicle lamp through the ventilation component so as to play a role in adjusting the air pressure in the vehicle lamp; however, the temperature and air pressure difference in the vehicle lamp still exists within a certain range; furthermore, moisture in the surrounding environment can also enter the vehicle lamp through the vent member, causing the vehicle lamp to fog. As the time for turning on the headlight increases, the temperature around the headlight is higher and higher, and the temperature of the air around the headlight is higher and higher, however, the temperature of the air far away from the corners of the headlight is relatively lower, and as the hot air collides with the cold air and impacts, the water in the air or the water in the material of the headlight easily forms water mist at the corners, which easily damages the components in the headlight; particularly, the water mist formed on the lampshade can influence the refraction of the light and the illumination effect because the light is emitted by the headlight and is refracted out by the lampshade, so that the driver of the opposite vehicle is easy to dazzle, and the potential safety hazard is great.

In contrast, most of the conventional defogging methods for vehicle lamps use a desiccant or an antifogging coating. The desiccant is typically a chemical desiccant such as calcium chloride that reduces the humidity within the lamp by combining with the water within the lamp to form hydrates that prevent fogging of the lamp. The antifogging coating enables the surface of the base material to have super-hydrophilic characteristics, increases the surface tension of water, enables water to be incapable of forming water drops on the surface of the base material, and is a water film on the surface of the base material in a flattened mode, so that light can normally pass through the base material without influencing the sight line, and the antifogging function is achieved.

When the automobile lamp works, the air pressure needs to be balanced with the outside, the automobile lamp is communicated with the outside atmosphere through the ventilation part, outside water vapor can continuously enter the lamp body, and after the desiccant absorbs moisture and is saturated, the desiccant can lose efficacy and needs to be replaced; even if a physical desiccant such as silica gel is used, it is difficult to achieve a good moisture absorption effect due to the high temperature environment inside the lamp. In addition, the antifogging coating can prevent the fog from forming fine fog beads on the surface of the lens, so that the sagging phenomenon is formed, and the appearance is influenced.

In view of the above, it is desirable to design a defogging system for a vehicle lamp.
