[0028] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0029] See attached document Figure 1 To be continued Figure 6 As shown, a pixel headlight includes a lens assembly 1, a heat dissipation assembly 2, a lamp panel 3, and a fixing assembly.

[0030] In one embodiment of this utility model, the lens assembly 1 includes a lens bracket and a first lens 12, a second lens 13 and a third lens 14 arranged sequentially within the lens bracket. The first lens 12, the second lens 13 and the third lens 14 are arranged sequentially from the outside to the inside along the length direction of the lens bracket. Textures can be added to each lens to block stray light, or baffles can be added to the lens bracket to block stray light.

[0031] In one embodiment of the present invention, the lens holder includes an upper housing 111 and a lower housing 112 that can be fastened to the upper housing 111. A cavity is provided between the upper housing 111 and the lower housing 112 for sequentially mounting a first lens 12, a second lens 13 and a third lens 14. Both the upper housing 111 and the lower housing 112 are made of metal. The upper housing 111 has a mounting groove on each side for screws to pass through, and the lower housing 112 has threaded holes on both sides corresponding to the mounting grooves.

[0032] In one embodiment of the present invention, the heat dissipation assembly 2 includes a heat sink 21 fixedly connected to the lens bracket, a fan 22 disposed on the side of the heat sink 21 away from the lens bracket, a rear cover 23 disposed on the side of the fan 22 away from the heat sink 21, and a first screw 24 for connecting the rear cover 23 and the fan 22. The rear cover 23 is hollowed out, which can effectively improve the heat dissipation effect.

[0033] In one embodiment of this utility model, the lamp plate 3 is disposed between the lens bracket and the heat sink 21. One side of the lamp plate 3 is fixedly connected to the heat sink 21, and the other side of the lamp plate 3 is provided with a set of LED beads arranged in a matrix (see attached diagram). Figure 6 This not only allows for independent control of each light-emitting unit to achieve dynamic effects, enabling the headlight to illuminate the road ahead more precisely and reduce glare for oncoming drivers, but also allows for independent control of each group of LEDs via external control components on the light panel 3. This ensures that the output paths of each group of LEDs pass through the third lens, the second lens, and the first lens in sequence, achieving a coordinated imaging design between the LEDs and lenses to ensure a clearer pattern.

[0034] In one embodiment of this utility model, the LED beads arranged in a matrix on the lamp panel 3 can be specifically divided into a low beam group 8 and a high beam group. The low beam group 8 is a small area of ​​LED beads on the lamp panel 3, while the high beam group is the entire matrix-arranged area of ​​LED beads. (Refer to the attached diagram.) Figure 6The lamp panel 3 is fixed on the heat sink 21. By controlling the imaging principles of the first lens 12, the second lens 13, and the third lens 14, the high beam and low beam of the projected light are controlled by the on / off state of the low beam group 8 and the high beam group. Furthermore, the high / low beam range, projected patterns and text, and dynamic effects can be customized by specifically controlling the on / off state of each lamp. It should be noted that the number of lamps arranged in a matrix can be set according to actual needs, and there is no limit to the specific number.

[0035] In one embodiment of this utility model, the external control component of the lamp board 3 can independently control each group of lamp beads. The centers of the first lens 12, the second lens 13 and the third lens 14 are set accordingly. The output path of each group of lamp beads passes through the third lens 14, the second lens 13 and the first lens 12 in sequence, which can realize the imaging design of lamp beads and lenses, so as to produce high and low beam effects, and can also project patterns, text and dynamic effects, etc., and meet the current customer demand for differentiated and personalized headlight design.

[0036] In one embodiment of the present invention, the fixing component includes second screws 4 respectively disposed at the four corners of the heat sink 21 on the side away from the lamp plate 3, which can fix the heat sink 21 to the lamp plate 3.

[0037] In one embodiment of the present invention, the outer circular surface of the upper housing 111 is provided with two first mounting protrusions 5 spaced apart, and the outer circular surface of the lower housing 112 is provided with two second mounting protrusions 6 spaced apart. The two first mounting protrusions 5 are symmetrically arranged, the two second mounting protrusions 6 are symmetrically arranged, and the first mounting protrusions 5 and the second mounting protrusions 6 located on the same side are correspondingly arranged.

[0038] In one embodiment of this utility model, the first mounting protrusion 5 and the second mounting protrusion 6 are respectively provided with a mounting hole 7, which can be square or round. The first mounting protrusion 5 and the second mounting protrusion 6 are respectively arranged radially along the upper housing 111 and the lower housing 112. This not only enables flexible assembly and adjustment, but also facilitates installation through a compact design. It is suitable for most lens vehicle models, simplifies the structural design, and makes assembly more convenient and simple.

[0039] In one embodiment of this utility model, a plurality of heat dissipation ribs 211 are provided at intervals on each side of the heat sink 21. The plurality of heat dissipation ribs 211 are arranged in the opposite direction along the length of the heat sink 21. By fixing the lens bracket to the heat sink 21, the lamp board 3 is fixed on the heat sink 21. The heat dissipation area can be further increased by the heat dissipation ribs 211 provided on each side of the heat sink 21, so that the lamp board 3 can conduct heat to the heat sink 21 and increase the heat dissipation efficiency.

[0040] This pixel headlight uses a lens bracket to sequentially mount a first lens 12, a second lens 13, and a third lens 14. These lenses are then secured to an upper housing 111 via a locking mechanism. A heat sink 21 is fixed to the lens bracket, and a lamp plate 3 is fixed to the heat sink 21. The lamps on the lamp plate 3 are arranged in a multi-LED matrix. (See attached diagram.) Figure 6 By independently controlling each light-emitting unit, the pixel headlight can illuminate the road ahead more accurately, reducing glare for oncoming drivers. By controlling the imaging principle of the three lenses, the light bulbs of each small LED are turned on and off to project high and low beams, as well as patterns, text, and dynamic effects.
