Description

Technical Field

[0001] The utility model belongs to the technical field of automobile lamps, and in particular relates to an integrated dual-light module. Background Art

[0002] Low beam and high beam are two types of lights commonly used in vehicle driving, each with specific functions and usage scenarios. Low beam is mainly used to provide an appropriate lighting distance and is used on urban roads and in places with heavy traffic to avoid interference with other vehicles and pedestrians; high beam is used to provide a longer lighting distance, allowing the driver to see the road conditions and obstacles in the distance more clearly, and is suitable for use when there are no other vehicles or pedestrians.

[0003] However, in actual driving, you often encounter situations where you need to flexibly switch between low beam and high beam. Using only low beam may not provide sufficient lighting distance. At this time, using high beam can increase the field of vision and improve the driver's safety. However, if you continue to use high beam in these situations, it may cause great interference and discomfort to other vehicles and pedestrians, because the strong light of high beam will directly shine into the eyes of other vehicles and pedestrians, affecting their vision.

[0004] To solve this problem, adaptive high beam came into being. Adaptive high beam uses advanced sensing technology and light control algorithms to intelligently adjust the brightness and range of the high beam according to the vehicle's surroundings and other traffic participants. When the system senses that there are other vehicles or pedestrians ahead, the adaptive high beam will automatically switch to low beam to avoid interfering with them; once the surroundings are restored to a safe distance, the adaptive high beam will automatically switch back to high beam to provide clearer lighting effects.

[0005] The combination of adaptive high beam and low beam can improve the safety and comfort of night driving. The driver does not need to switch lights manually, the system will make the best light selection based on real-time perception and analysis. This intelligent light control technology not only provides a better field of view and lighting effects, but also reduces the burden on the driver, making driving more convenient and efficient.

[0006] However, the dual-light module of the adaptive high beam and low beam in the prior art still has the following disadvantages: 1. The two lamps are independent of each other in structure, so the tolerances introduced are relatively large and difficult to control in actual production, and finally the dual-light fusion effect is not good; 2. The two lamps usually adopt conventional adaptive high beam and low beam, and the size and space of the whole lamp are large, which is insufficient in miniaturization and lightweight; 3. The two lamps have their own decorative rings and styling surfaces, and the whole lamp has a heavy sense of splicing and lacks styling aesthetics. Utility Model Content

[0007] The purpose of the utility model is to solve the defects and shortcomings in the prior art and to design an integrated dual-light module which has a simple structure, is stable and reliable, has a reduced size and improves the fusion effect.

[0009] Preferably, the light output lens has a front end face and a rear end face, and the front end face is a plane.

[0010] Preferably, the light output lens divides the areas corresponding to the high beam lamp assembly and the low beam lamp assembly into a first area and a second area, the focal lengths of the first area and the second area are f1 and f2 respectively, and f1≠f2.

[0011] Preferably, the first area of ​​the light output lens has a pattern structure, and the pattern structure is located on the rear end surface of the first area.

[0013] Preferably, the high beam lamp assembly and the low beam lamp assembly are independent of each other in the light path, and a light blocking structure is provided to avoid crosstalk between lamps.
