Description

Integrated double-light module

Technical Field

The utility model belongs to the technical field of automobile lamps, and particularly relates to an integrated double-light module.

Background

Dipped and high beam lights are one of the types of lights commonly used in vehicle driving, each having a specific function and use scene. The low beam is mainly used for providing proper illumination distance, is used in urban roads and places with heavy traffic to avoid interference to other vehicles and pedestrians, and the high beam is used for providing farther illumination distance, so that a driver can more clearly see road conditions and obstacles at the far place, and is suitable for being used without other vehicles and pedestrians.

However, in actual driving, a situation where a flexible switching between low beam and high beam is required is often encountered. Using only low beam lights may not provide sufficient illumination distance. At this time, the vision range can be increased by using the high beam, and the safety of the driver is improved. However, if the high beam is used continuously in these cases, it may cause great interference and discomfort to other vehicles and pedestrians because the strong light of the high beam may directly strike the eyes of other vehicles and pedestrians, affecting their vision.

To solve this problem, an adaptive high beam lamp has been developed. The self-adaptive high beam adopts advanced sensing technology and light control algorithm, and can intelligently adjust the brightness and range of the high beam according to the surrounding environment of the vehicle and the conditions of other traffic participants. When the system senses that other vehicles or pedestrians are in front, the self-adaptive high beam lamp can be automatically switched to the low beam lamp so as to avoid interference to the low beam lamp, and once the surrounding is recovered to a sufficient safety distance, the self-adaptive high beam lamp can be automatically switched back to the high beam lamp so as to provide a clearer lighting effect.

Through the collocation of self-adaptation distance light and dipped headlight, can improve the security and the travelling comfort that drive night. The driver does not need to manually switch the lamplight, and the system can make optimal lamplight selection according to real-time sensing and analysis. The intelligent light control technology not only provides better visual field and lighting effect, but also lightens the burden of a driver, and ensures that the driving is more convenient and efficient

However, the dual-light module matched with the self-adaptive high beam and the low beam in the prior art has the following defects that 1, the two lamps are structurally independent, so that the introduced tolerance is more, the control is difficult in actual production, the final dual-light fusion effect is poor, 2, the two lamps generally adopt the conventional self-adaptive high beam and low beam, the whole lamp size space is large, the lamp miniaturization and the light weight are not enough, 3, the two lamps have respective decorative rings and molding surfaces, the whole lamp splicing sense is heavy, and the molding aesthetic feeling is lacking.
