Description

Technical fields:

[0002] Most LED car lights on the market are currently bi-directional, such as the utility model patent CN207394717U, which discloses an LED car light structure. One end of the lamp holder has a mounting bracket, and the other end has a heat dissipation cover. The lamp body, containing LED beads, passes through the mounting bracket and is fixed to the lamp holder. Electrodes for connecting to the automotive circuitry are located on the outer wall of the mounting bracket. Inside the lamp holder is a driving circuit board that drives the lamp body to emit light, and the driving circuit board is connected to the electrodes of the mounting bracket via wires. This LED car light structure is compact, effectively reducing the size of the equipment, making installation and disassembly extremely convenient, and making more efficient use of the space inside the car headlight. It also better protects the automotive circuitry, preventing damage to the original circuit structure while ensuring the LED light's functionality, thus improving the car's electrical safety.

[0003] However, in the aforementioned patent, due to limitations in the LED light emission angle (120 degrees) and the obstruction of the light source board between two LEDs, such as... Figure 1 As shown, when the light is emitted, there is a shadow on the side perpendicular to the light source plate that cannot be covered by the light, and correspondingly, dark areas will also be generated when the light emitted through the assembly is paved.

[0004] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0021] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0022] See Figures 1 to 5 As shown, a vehicle headlight structure for reducing dark areas is illustrated, including a light source module 1. This module comprises a first light source plate 11, a second light source plate 12, and a V-shaped component 13 disposed between the first and second light source plates 11 and 12. The V-shaped component 13 tilts the LEDs on the first and second light source plates 11 and 12, thereby reducing dark areas. By placing two LEDs on the first and second light source plates 11 and 12 respectively, and using the V-shaped component 13 between them, the areas illuminated by the symmetrically distributed LEDs are brought closer together, achieving the effect of tilting the LEDs and reducing dark areas. The V-shaped component 13 is made of aluminum.

[0023] A copper tube 14 is provided on one side of the light source board module 1. The first light source board 11, the second light source board 12, and the V-shaped component 13 are respectively provided with a first groove 11A, a second groove 12A, and a third groove 13A for positioning the copper tube 14. By providing a copper tube 14 on the side of the light source board module 1, the heat dissipation effect is improved, and the heat generated by the lamp beads in the upper part of the light source board module 1 is transferred to the lower part, avoiding high temperature damage to the lamp beads.

[0024] The copper tube 14 is fixed in the first groove 11A, the second groove 12A and the third groove 13A by welding.

[0025] At least one first LED bead 1A and one second LED bead 1B are respectively provided on the sidewalls of the first light source board 11 and the second light source board 12. The first LED bead 1A and the second LED bead 1B are symmetrically located on both sides of the light source board module 1.

[0026] The light source board module 1 has a first heat sink 2 and a second heat sink 3 on both sides for dissipating heat from the first LED bead 1A and the second LED bead 1B. By placing the first heat sink 2 and the second heat sink 3 at the bottom of the light source board module 1, the heat generated by the first LED bead 1A and the second LED bead 1B is quickly dissipated by the heat dissipation fins on the first heat sink 2 and the second heat sink 3.

[0027] A drive module 4 is provided at the lower end of the light source board module 1. The drive module 4 includes a fan 41, a drive board 42, and a connector 43. The fan 41 is located below the first heat sink 2 and the second heat sink 3. By placing the fan 41 below the first heat sink 2 and the second heat sink 3, the airflow generated by the fan 41 removes heat from the surfaces of the first heat sink 2 and the second heat sink 3, achieving efficient heat dissipation for the first LED bead 1A and the second LED bead 1B, and preventing high-temperature damage.

[0028] The lower ends of the first light source board 11 and the second light source board 12 are electrically connected to the drive board 42.

[0029] The light source board module 1 is also equipped with a lamp body 5. The lamp body 5 includes a first housing 51 and a second housing 52 that are symmetrically fastened and held on the light source board module 1, and a first screw 53, a second screw 54 and a third screw 55 for mounting and fixing the first housing 51 and the second housing 52. The first housing 51 and the second housing 52 are each provided with a first light hole 511 and a second light hole 521 corresponding to the lamp beads.

[0030] The first screw 53 is located at the upper end of the lamp body 5 and passes through the light source board module 1. The second screw 54 and the third screw 55 are located at the lower end of the lamp body 5 and are respectively fixed on both sides of the plug 43.

[0031] In summary, in this utility model, the first light source board 11 and the second light source board 12 are welded together with the V-shaped part 13 using a fixture to form a light source board module 1. Then, the light source board module 1 is welded together with the copper tube 14 using a fixture. Furthermore, the fan 41 and the drive board 41 are welded together using a fixture to form a "drive semi-finished product". Then, the light source board module 1 is welded together with the "drive semi-finished product" using a fixture. An electronic wire is used to connect the plug 43 to the pad position of the drive board semi-finished product to form a circuit. Furthermore, the first heat sink 2, the light source board module 1, and the second heat sink 3 are fixed together using a fixture using a fourth screw 56. Then, the first housing 51 and the second housing 52 are fastened to the light source board module 1 and fixed using a first screw 53, a second screw 54, and a third screw 55.

[0032] In the above solution, the traditional single light source board is replaced with two boards, and the tilt angle of the lamp beads is adjusted by an inclined aluminum component in the middle to compensate for the blind spot of light emission in a certain direction, thus making up for the shortcomings of the existing dark light emission area.
