Description

Technical Field

[0001] This utility model belongs to the field of matrix light panels, and specifically relates to a matrix light panel that integrates high and low beams. Background Technology

[0002] Matrix headlights are an advanced lighting technology that uses multiple independently controlled LED light-emitting units arranged in a matrix to achieve precise beam control and dynamic lighting effects. Their core advantage lies in their ability to adjust the lighting area and brightness in real time according to road conditions, vehicle speed, and the surrounding environment. However, if a matrix headlight panel lacks integrated high and low beam functionality, it will exhibit significant drawbacks. Firstly, non-integrated high and low beam modules require separate reflectors, lenses, and drive circuits, each occupying physical space. This dispersed layout further increases the overall size. Given the limited space in the vehicle's headlight assembly, an excessively large headlight panel will encroach on the mounting positions of other components and may even affect the aerodynamic performance of the vehicle's front end. Therefore, we aim to design a matrix headlight panel with integrated high and low beams to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a matrix-type integrated high and low beam light panel to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a matrix-type integrated high and low beam light panel, comprising: a lamp housing, a heat dissipation mechanism provided at the rear end of the lamp housing, and an adjustment mechanism for adjusting the focal length provided inside the lamp housing;

[0005] The adjustment mechanism includes a threaded rod, with a connecting block screwed onto the outer side of the threaded rod. Four sets of fixing rods are fixedly connected to the outer surface of the connecting block. A lens assembly is fixedly connected to the other end of the fixing rod. A drive motor is fixedly installed at the inner rear end of the lamp housing. The output shaft of the drive motor is fixedly connected to the threaded rod via a coupling. By setting up the adjustment mechanism, the threaded movement generated by the threaded rod and the connecting block causes the lens assembly to shift to adjust the focal length. This allows for rapid switching between high beam and low beam on a single lamp, making the structure more compact and saving installation space.

[0006] In a preferred embodiment, the lamp housing is fixedly connected to the left and right ends of the lamp bead plate and the lamp bead plate one, respectively. The left side surface of the lamp bead plate and the lamp bead plate one are provided with matrix LED beads. The outside of the lamp housing is fixedly connected with a connecting ear, and the connecting ear has a threaded groove inside.

[0007] In a preferred embodiment, a transparent protective cover for protecting the second lamp bead plate and the first lamp bead plate is fixedly connected to the front side of the lamp housing.

[0008] In a preferred embodiment, a limiting rod is fixedly connected to the right side surface of the second lamp bead plate, and the limiting rod is slidably sleeved inside the connecting block.

[0009] In a preferred embodiment, the heat dissipation mechanism includes heat dissipation fins. The heat dissipation fins are attached to and fixedly connected to the rear surface of the LED bead plate through a heat conduction layer inside the lamp housing. The lamp with the heat dissipation mechanism can effectively reduce the operating temperature and prevent the LED or light source from light decay, shortening of life or damage due to overheating, thereby improving the stability and durability of the lamp.

[0010] In a preferred embodiment, the heat dissipation mechanism further includes a heat dissipation rear cover plate, on the outer side of which a fixing ear is fixedly connected. The fixing ear and the connecting ear are connected by external screws. A heat dissipation channel group is also provided on the heat dissipation rear cover plate.

[0011] In a preferred embodiment, a sealing strip is fixedly fitted between the heat dissipation back cover and the lamp housing.

[0012] In a preferred embodiment, the heat dissipation channel group includes an air inlet channel one, an air inlet channel two, and a heat dissipation channel. The air inlet channel one is located at the lower end of the heat dissipation rear cover plate, the air inlet channel two is located on the lower side of the lamp housing, and the heat dissipation channel is located on the upper side of the heat dissipation rear cover plate and has a heat dissipation fan fixedly installed inside for creating an air pressure difference between the inside of the lamp housing and the outside.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. By setting an adjustment mechanism, the screw motion generated by the screw rod and the connecting block causes the lens group to shift to adjust the focal length, thereby enabling rapid switching between high beam and low beam on a single lamp, making the structure more compact and saving installation space.

[0015] 2. Light fixtures with heat dissipation mechanisms can effectively reduce operating temperature, preventing LEDs or light sources from overheating and causing light decay, shortened lifespan, or damage, thereby improving the stability and durability of the light fixtures.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 As the first embodiment of this utility model:

[0027] A matrix-type integrated high and low beam light panel includes: a lamp housing 1, a heat dissipation mechanism 2 provided at the rear end of the lamp housing 1, and an adjustment mechanism 3 for adjusting the focal length provided inside the lamp housing 1.

[0028] The adjustment mechanism 3 includes a threaded rod 31, with a connecting block 32 screwed onto the outer side of the threaded rod 31. Four sets of fixing rods 33 are fixedly connected to the outer surface of the connecting block 32. A lens group 34 is fixedly connected to the other end of the fixing rod 33. A drive motor 36 is fixedly installed on the inner rear end of the lamp housing 1. The output shaft of the drive motor 36 is fixedly connected to the threaded rod 31 through a coupling. By setting the adjustment mechanism 3, the threaded movement generated by the threaded rod 31 and the connecting block 32 causes the lens group 34 to move to adjust the focal length. This allows for rapid switching between high beam and low beam on a single lamp, making the structure more compact and saving installation space.

[0029] The lamp housing 1 is fixedly connected to the left and right ends of the lamp bead plate 2 14 and the lamp bead plate 13 respectively. The left side surface of the lamp bead plate 2 14 and the lamp bead plate 13 is provided with matrix LED beads. The lamp housing 1 is fixedly connected to the outside of the lamp housing 1 with a connecting ear 12. The connecting ear 12 has a threaded groove inside.

[0030] A transparent protective cover for protecting the second lamp bead board 14 and the first lamp bead board 13 is fixedly connected to the front side of the lamp housing 1.

[0031] A limiting rod 35 is fixedly connected to the right side surface of the LED bead board 14, and the limiting rod 35 is slidably sleeved inside the connecting block 32.

[0032] Specifically, when the position of the lens group 34 needs to be adjusted to achieve focal length adjustment, the drive motor 36 is started. During the operation of the drive motor 36, the threaded rod 31 on its output shaft rotates. During the rotation, the threaded rod 31 moves with the connecting block 32, thereby causing the lens group 34 to be displaced. By adjusting the distance between the lens group 34 and the LED light source, the refraction angle and focusing position of the light can be changed, thereby achieving rapid switching between high beam and low beam on a single lamp, making the structure more compact and saving installation space.

[0033] Please see Figure 1 , Figure 2 as well as Figure 4 As a second embodiment of this utility model:

[0034] The heat dissipation mechanism 2 includes heat dissipation fins 21. The heat dissipation fins 21 are attached to and fixedly connected to the rear surface of the LED bead board 13 through a heat conduction layer 22 inside the lamp housing 1. The lamp with the heat dissipation mechanism 2 can effectively reduce the operating temperature and prevent the LED or light source from light decay, shortening of life or damage due to overheating, thereby improving the stability and durability of the lamp.

[0035] The heat dissipation mechanism 2 also includes a heat dissipation rear cover plate 23. A fixing ear 231 is fixedly connected to the outer side of the heat dissipation rear cover plate 23. The fixing ear 231 is connected to the connecting ear 12 by an external screw. A heat dissipation channel group 25 is also provided on the heat dissipation rear cover plate 23.

[0036] A sealing strip 24 is fixedly fitted between the heat dissipation cover plate 23 and the lamp housing 1.

[0037] The heat dissipation channel group 25 includes an air inlet channel 1 251, an air inlet channel 252, and a heat dissipation channel 253. The air inlet channel 1 251 is located at the lower end of the heat dissipation rear cover plate 23, the air inlet channel 252 is located on the lower side of the lamp housing 1, and the heat dissipation channel 253 is located on the upper side of the heat dissipation rear cover plate 23 and has a heat dissipation fan 232 fixedly installed inside to create an air pressure difference between the inside of the lamp housing 1 and the outside.

[0038] Based on the above embodiments, further, during the lighting process, the cooling fan 232 is activated. Since the LED beads on the first LED bead board 13 are more densely packed than those on the second LED bead board 14, a heat dissipation mechanism 2 is integrated on the first LED bead board 13. During the LED lighting process, the heat generated is first conducted to the first LED bead board 13, and then transferred to the heat dissipation fins 21 through the heat conduction layer 22. The heat conduction layer 22 is thermally conductive silicone grease. Simultaneously, the cooling fan 232 is activated. During operation, the cooling fan 232 creates an air pressure difference between the inside of the lamp housing 1 and the outside, causing the outside air to flow rapidly into the inside of the lamp housing 1. At the same time, the rapidly flowing air achieves convective heat exchange with the heat dissipation fins 21, thereby reducing the temperature difference between the heat dissipation fins 21 and the surrounding environment and preventing heat accumulation.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
