Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to an intelligent matrix LED headlight based on ADAS. Background Technology

[0002] Automotive headlights, including high beams and low beams, are one of the key components of a car. They are used to provide road lighting in situations such as nighttime or insufficient ambient light, different road scenarios or transitions between different road scenarios, and different weather conditions. Good lighting performance provides important assurance for driving comfort and driving safety.

[0003] Intelligent automotive headlight systems have become the mainstream development direction in the automotive lighting industry. They can combine with advanced driver assistance systems (ADAS) to collect vehicle and environmental data inside and outside the vehicle in real time. Through the identification, detection and tracking of static and dynamic objects, they can assist drivers in quickly changing the light field in front of the vehicle to avoid potential dangers of night driving. Moreover, by utilizing its pixel-level control capabilities, it can project images onto the road in front of the vehicle to provide better guidance information for drivers and pedestrians, greatly improving the safety of road vehicle functions.

[0004] In existing automotive headlight products, matrix LED headlights achieve intelligent features such as avoiding oncoming vehicles and adaptive lighting by individually controlling each LED unit in the matrix. The headlights use multiple lens modules to achieve their high and low beams. Typically, a single lens module can only achieve low beam or high beam by switching the light-blocking plate, resulting in insufficient high beam brightness in such headlights. Utility Model Content

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] As attached Figure 1 To be continued Figure 4 . Specific implementation examples:

[0021] The ADAS-based intelligent matrix LED headlight includes a heat sink housing 1, a low beam LED panel 2, and a high beam LED panel 3. A low beam lens 4 and a high beam lens 5 are located at the front of the heat sink housing 1. A base 6 is located on the inner bottom surface of the heat sink housing 1, with an inclined front surface and a flat top. The low beam LED panel 2 is fixed to the front surface, and a low beam focusing lens 7 is fixed on it. A multi-curved reflector 8 is located on the top of the base 6. The multi-curved reflector 8 is horizontally movable and connected to a drive module 9. The light emitted from the low beam LED panel 2 is focused by the low beam focusing lens 7 onto the multi-curved reflector 8, and the reflected light from the multi-curved reflector 8 exits from the low beam lens 4. The high beam LED panel 3 is fixed to the inner top of the heat sink housing 1, and a high beam focusing lens 10 is fixed on it. The light emitted from the high beam LED panel 3 is focused by the high beam focusing lens 10 and exits from the high beam lens 5.

[0022] The multi-curved reflector 8 is composed of multiple curved surfaces with different curvatures. By horizontally moving the multi-curved reflector 8 through the drive module 9, the position of the light emitted by the low beam LED panel 2 onto the multi-curved reflector 8 can be adjusted, thereby adjusting the reflection direction of the low beam. In conjunction with the low beam lens 4, the final projection area of ​​the low beam can be adjusted. With the help of an advanced driver assistance system (ADAS), the height of the low beam can be automatically adjusted. If the final projection area is far enough, the effect of high beam can also be achieved, but the brightness will be lower. To enhance the brightness of the high beam, this invention also includes a high beam LED panel 3. The high beam LED panel 3 directly projects light to form a high-brightness area. Some of the light is reflected back by the high beam focusing lens 10 and then re-projected to further enhance the light intensity and improve the light utilization rate. It can be used with an advanced driver assistance system (ADAS) to achieve automatic switching.

[0023] The heat dissipation housing 1 includes an upper heat dissipation housing 11 and a lower heat dissipation housing 12, which are fixed together by bolts for easy disassembly and installation.

[0024] The base 6 is fixed to the lower heat sink 12. An L-shaped base plate 13 is fixed to the front end of the base 6, and the low beam LED light panel 2 is fixed to the base plate 13. The base plate 13 is made of thermally conductive material. An L-shaped connecting plate 14 is fixed to the upper heat sink 11, and the high beam LED light panel 3 is fixed to the connecting plate 14. The connecting plate 14 is made of thermally conductive material. The thermally conductive material is preferably aluminum alloy or copper alloy.

[0025] Multiple heat dissipation fins 15 are fixed at the top rear of the base 6. A cooling fan 16 is also located at the rear of the base 6. The cooling fan 16 is close to the end plate 17 at the rear of the heat dissipation housing 1. The end plate 17 has multiple heat dissipation holes. The heat dissipation fins 15 can increase the heat dissipation area and, together with the cooling fan 16, achieve rapid heat dissipation.

[0026] The drive module 9 is fixed to the bottom of the base 6 and can drive the multi-curved reflector 8 to move horizontally.

[0027] Both the low-beam focusing lens 7 and the high-beam focusing lens 10 are bowl-shaped structures with open front ends, and are fixed upside down on the low-beam LED light panel 2 or the high-beam LED light panel 3. Most of the light is emitted directly through the opening, while the other part of the light is reflected by the inner reflective surface of the focusing lens to the reflective surface of the light panel to form a secondary reflection and then emitted from the opening, thus improving the light utilization rate.

[0028] It should be noted that both the low beam LED light panel 2 and the high beam LED light panel 3 of this utility model are equipped with multiple LED beads, each of which can be controlled separately. They can work with the Advanced Driver Assistance System (ADAS) to automatically illuminate according to road conditions and freely combine light patterns to adapt to different scenarios.

[0029] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection of the claims of this application.
