Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile intelligent headlights, and more specifically, to a compact module for realizing an ADB function of a headlight. Background Art
[0002] The wave of automobile intelligence and the continuous iteration of underlying light source technology have driven the evolution of car lights from the previous single lighting to the direction of intelligence and emotion. ADB headlights that can achieve intelligent lighting, projection interaction and more styling possibilities are becoming a new trend. The full name of ADB is Adaptive Driving Beam, which means automatic adaptation to the high beam system. ADB is an intelligent high beam control system that can automatically change the light type of the high beam according to the current road conditions. Equipped with an ADB lighting system on the car, it can reduce the impact on other vehicles. Compared with other traditional high beams, ADB can replace the driver's manual operation, making the car lighting control more convenient and improving the safety of the driver's field of vision.
[0003] The car's ADB lighting system is very smart. When the owner is following or meeting a car, the ADB system can automatically capture the position of other vehicles and dim or turn off the lights to prevent dazzling other vehicles. At present, the optical solution of the ADB module is relatively complex and costly. If you need to achieve two or more rows of partitions, you often need to use a silicone lens array plus a lens composed of multiple lenses to achieve it, or use two or more rows of closely spaced small-sized light-emitting LEDs plus a lens composed of multiple lenses to achieve it. These two implementation methods require more optical parts and the total cost is higher.
[0004] The utility model patent with announcement number CN217503537U discloses an ADB module with an adjustable concentrator structure, including: a heat sink, on which a first through hole and a second through hole are provided; and a circuit board, which is located on one side of the heat sink and on which a third through hole is provided at a position corresponding to the first through hole; and a plurality of light sources, which are mounted on the circuit board; and a concentrator, which is located on a side of the circuit board close to the light source and is fixedly connected to the circuit board, a first threaded hole is provided at a position corresponding to the third through hole on the concentrator, and the concentrator includes an adjustment column, which passes through the second through hole and leaves a gap between the adjustment column and the second through hole.
[0005] However, the above technical solution only supports automatic adjustment of high beam or low beam status, that is, it only adjusts the row status, and cannot satisfy the adjustment of a single position status. In view of this, the utility model proposes a compact module for realizing the ADB function of the car light, and provides a solution with simple structure and compact shape to realize two or more rows of ADB with independent control of light and dark partitions. Utility Model Content

The focal plane of the lens 2 is located between the central LED light source 4 of all lighting modules 1 and the top edge of the central reflector 5, or is located near the light-emitting chip of the central LED light source 4 of all lighting modules 1. When the reflector 5 far away from the incident area 6 collects the light of the corresponding LED light source 4 and reflects it, a part of the light will be blocked by the reflector 5 close to the incident area 6, and the remaining part of the light enters the lens 2 and forms a clear and complete light and shadow in the imaging area 8 through the lens 2, so that when a certain LED light source 4 is turned off or dimmed, the corresponding clear and complete light and shadow formed in the imaging area 8 disappears or becomes dark.
[0007] In some embodiments, each of the reflectors 5 can be a parabola, an ellipsoid, a hyperboloid, or a composite surface based on these surface shapes, and each of the LED light sources 4 is arranged at an upper position facing the corresponding reflector 5 to facilitate better collection of the light of the corresponding LED light source 4 and reduce the loss of light energy.
[0008] Furthermore, the surface of the lens 2 is smooth or has a micro-optical structure to achieve the light pattern boundary requirements of different customers.
[0009] In some embodiments, the position of the light board 3 in the light module 1 determines the specifications of the corresponding reflector 5 on each light board 3 .
[0010] Furthermore, taking the direction of the lens 2 as the vertical direction, when the light board 3 is placed in the horizontal direction, that is, the light board 3 and the lens 2 are perpendicular to each other, the specifications of the reflector 5 corresponding to each LED light source 4 on the light board 3 are different, that is, the vertical height of each reflector 5 away from the incident area 6 is greater than the vertical height of the adjacent reflector 5 close to the incident area 6.
[0011] Furthermore, taking the direction of the lens 2 as the vertical direction, when the light board 3 is placed in the vertical direction, that is, the light board 3 and the lens 2 are parallel to each other, the specifications of the reflectors 5 corresponding to each LED light source 4 on the light board 3 are the same, and the vertical height of each reflector 5 on the light board 3 away from the incident area 6 is greater than the vertical height of the reflector 5 on the adjacent light board 3 close to the incident area 6.

The vertical height of each reflector 5 far away from the incident area 6 is greater than the vertical height of the adjacent reflector 5 close to the incident area 6. The focal plane of the lens 2 is located between the central LED light source 4 of all lighting modules 1 and the top edge of the central reflector 5, or is located near the light-emitting chip of the central LED light source 4 of all lighting modules 1. When the reflector 5 far away from the incident area 6 collects the light of the corresponding LED light source 4 and reflects it, a part of the light will be blocked by the reflector 5 close to the incident area 6, and the remaining part of the light enters the lens 2 and forms a clear and complete light and shadow in the imaging area 8 through the lens 2, so that when a certain LED light source 4 is turned off or dimmed, the corresponding clear and complete light and shadow formed in the imaging area 8 disappears or becomes darker.

The compact module for realizing the ADB function of a vehicle light according to claim 1, characterized in that: Each of the reflectors (5) is a parabola, an ellipsoid, a hyperboloid, or a composite surface based on these surfaces. The light sources (4) are all arranged at upper positions facing the corresponding reflectors (5), so as to better collect the light of the corresponding LED light sources (4) and reduce the loss of light energy.
3. The compact module for realizing the ADB function of a vehicle light according to claim 1, characterized in that: The lens (2) has a smooth surface or a micro-optical structure to achieve the light pattern boundary requirements of different customers.
4. The compact module for realizing the ADB function of a vehicle light according to claim 1, characterized in that: The position of the light panels (3) in the light module (1) determines the specifications of the corresponding reflectors (5) on each light panel (3).
5. The compact module for realizing the ADB function of a vehicle light according to claim 1, characterized in that: With the direction of the lens (2) as the vertical direction, when the light board (3) is placed in the horizontal direction, that is, the light board (3) and the lens (2) are perpendicular to each other, the reflectors (5) corresponding to each LED light source (4) on the light board (3) have different specifications, that is, the vertical height of each reflector (5) away from the incident area (6) is greater than the vertical height of the adjacent reflector (5) close to the incident area (6).
6. The compact module for realizing the ADB function of a vehicle light according to claim 1, characterized in that: With the direction of the lens (2) as the vertical direction, when the light board (3) is placed in the vertical direction, that is, the light board (3) and the lens (2) are parallel to each other, the reflectors (5) corresponding to each LED light source (4) on the light board (3) have the same specifications, and the vertical height of each reflector (5) on the light board (3) far from the incident area (6) is greater than the vertical height of the reflector (5) on the adjacent light board (3) close to the incident area (6).
