[0016] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0017] like Figures 1 to 3 As shown, a bidirectional projection automotive headlight includes: a first housing 1, a second housing 2, a lens 3, a mounting base 4, a mounting tube 5, a reflector 6, and a plug 7. The first housing 1 and the second housing 2 are joined together. One end of the first housing 1 and the second housing 2 is respectively provided with an arc-shaped groove 9. A protruding post is provided on each of the opposite sides of the two joined arc-shaped grooves 9. Each arc-shaped groove 9 is connected by two protruding posts to form a semi-circular frame. The two semi-circular frames are combined to form a circular frame. The first housing 1 and the second housing 2 are each provided with a storage compartment 11, and the two storage compartments 11 face the arc-shaped grooves respectively. A placement slot is provided on one side of the 9, and each placement slot is filled with an LED bead 8. A cooling fan 101 is placed between the two storage compartments 11. A fixing tube 5 is connected to the side of each storage compartment 11 away from the corresponding arc-shaped groove 9. The two fixing tubes 5 are combined into a set of tubes, and a limiting plate 71 is clamped inside the two fixing tubes 5. The outer side of the round frame composed of two semi-circular frames is provided with external threads, and the round frame is connected to a limiting frame 31 by external thread engagement. A lens 3 is clamped between the limiting frame 31 and the round frame. The second housing 2 is located on the side away from the first housing 1, and a reflector 6 is installed at the edge of the placement slot.

[0018] After the first housing 1 and the second housing 2 are spliced ​​together, they are installed inside the external headlight cover. Several plugs 7 located at the ends of the first housing 1 and the second housing 2 are electrically connected to the car power supply to achieve power supply. After the car power supply is electrically connected to this utility model, the lamp beads 8 placed in the two placement slots emit light outward. One of the lamp beads 8 projects the light into the reflector cup 6, and then refracts it in one direction through the reflector cup 6. This setting is used to project the light in one direction, thereby achieving the projection of light in one direction. The other lamp bead 8 projects light into the headlight cover, and then refracts the light outward through the headlight cover to enhance the brightness of the light projected outward by the headlight.

[0019] With the above structure, it should be further explained that the surfaces of the arc grooves 9 of the first housing 1 and the second housing 2 are flush. The arc grooves 9 are designed to make the lower half of the light pattern refracted by the reflector cup 6 present an arc shape, while the upper half is compressed into a line, which can make the light pattern illumination more extensive.

[0020] The two semicircular frames are respectively equipped with two protruding pillars that are far away from the first housing 1 and the second housing 2. This arrangement is used to place the lens 3 in a position so that it is at a distance that allows light to be focused and projected.

[0021] The limiting frame 31, which is fixed outside the circular frame, has a through hole at its center. This through hole is used to fill the convex surface of the lens 3 and can also provide further limiting and fixing.

[0022] Two fixing tubes 5 are respectively fixed to the first housing 1 and the second housing 2, and the two fixing tubes 5 are combined into a set of tubes by the installation of the first housing 1 and the second housing 2, which also fixes the limiting plate 71 vertically.

[0023] A copper substrate 10 is sandwiched between the first housing 1 and the second housing 2; the first housing 1 or the second housing 2 is integrally formed with the corresponding storage compartment 11, the corresponding semi-circular frame, and the corresponding fixing tube 5; each storage compartment 11 has several heat dissipation grooves 12, which extend into the storage compartment 11 and face outwards from the cooling fan 101; outside the first housing 1 and the second housing 2, and facing one side of the two fixing tubes 5, there is an outwardly extending fixing seat 4; each fixing seat 4 has a limiting chuck 41 extending outwards from its edge, and the limiting chuck 41 has several fixing protrusions 42 at its edge.

[0024] With the above structure, it should be further explained that when the cooling fan 101 dissipates the heat emitted by the copper substrate 10 and the two LED beads 8, the heat is discharged to the outside through the heat dissipation grooves 12, thereby reducing the accumulation of heat in the first housing 1 and the second housing 2.

[0025] After the first housing 1 and the second housing 2 are combined, the fixing seats 4 respectively provided on them are circular and are embedded in the mounting holes reserved in the car lamp cover. The limiting chuck 41 provided on the edge of the fixing seat 4 is used to limit the present invention in the car lamp cover, and finally it is fixed by several fixing protrusions 42.

[0026] The first housing 1 and the second housing 2 are respectively fixed to the external headlight cover by a limiting chuck 41 and a fixing protrusion 42.

[0027] With the above structure, it should be further explained that the inner wall of the headlight cover of this utility model is provided with reflective material, so that the light projected by the lamp bead 8 can be refracted toward the opening of the headlight cover.

[0028] A copper substrate 10 faces each side of the placement slot, and an LED bead 8 is mounted on each side and electrically connected to the other. A mounting hole is formed in the copper substrate 10, and a cooling fan 101 is embedded in the mounting hole. The outer edge of the cooling fan 101 is fixed to the edge of the mounting hole of the copper substrate 10, and the cooling fan 101 is electrically connected to the copper substrate 10. A terminal block 102 is provided at the end of the copper substrate 10 away from the two LED beads 8, and the copper substrate 10 and the terminal block 102 are linearly electrically connected.

[0029] With the above structure, it should be further explained that the cooling fan 101 is embedded in the mounting hole of the copper substrate 10, and the copper substrate 10 divides the cooling fan 101 into upper and lower exhaust areas. This arrangement allows the cooling fan 101 to blow the heat emitted by the upper and lower sides of the copper substrate 10 and the lamp beads 8 connected to the upper and lower sides outward, thereby realizing the heat dissipation from the inside of the first housing 1 and the second housing 2.

[0030] The plug 7 is provided with at least three plugs, and one end of each plug extends outward; the three plugs 7 are respectively facing one end of the first housing 1 and the second housing 2, and are connected to a limiting plate 71. The limiting plate 71 is used to fix the three plugs 7 and allow the three plugs to be connected to the external power source.

[0031] With the above structure, it should be further explained that the three plugs 7 are the live wire terminal, the neutral wire terminal, and the ground wire terminal, respectively, and are electrically connected to the three wiring connections of the car lights. This setting can improve the safety of electrical connection of this utility model.

[0032] After the three plugs 7 are connected to the external power source, the inward-facing ends of the three plugs 7 extend inward and connect to the copper substrate 10, and the power is transmitted to the copper substrate 10 and the terminal block 102 through the three plugs 7.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
