[0022] 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.

[0023] like Figs. 1 to 4As shown, a vehicle headlight with dual heat dissipation includes: a first housing 1, a second housing 2, a reflector 3, a heat sink assembly 4, a cooling fan 5, a socket 6, and a mounting frame 7. The second housing 2 covers one side of the first housing 1. A slot is formed on the outer side of the first housing 1, and a reflector 3 is placed in the slot. A copper substrate 8 is sandwiched between the first housing 1 and the second housing 2. A heat sink assembly 4 is embedded on the front and back surfaces of the copper substrate 8, respectively. A cooling fan 5 is connected to one end and edge of the copper substrate 8. A socket 6 is embedded at one end of the first outer shell 1 and the second outer shell 2; a vertically placed ring is provided at the opposite end of the first outer shell 1 and the socket 6, and is connected to the first outer shell 1 and the ring by two protruding pillars. The ring of the first outer shell 1 has an external thread on the side away from the two protruding pillars. The ring of the first outer shell 1 is connected to the fixing frame 7 by the thread; a cavity is provided between the first outer shell 1 and the second outer shell 2, and a heat sink assembly 4, a cooling fan 5 and a copper substrate 8 are wrapped in the cavity of the first outer shell 1 and the second outer shell 2.

[0024] After the first outer shell 1 and the second outer shell 2 are assembled and formed, they are fixed inside the external vehicle light. After being electrically connected to the vehicle through the socket 6, the external power source transmits electrical energy to the copper substrate 8, and the lamp beads embedded in the copper substrate 8 emit light outward. The diffused light is refracted by the reflector cup 3 and concentrated and projected in one direction.

[0025] In this invention, during the continuous operation of the copper substrate 8 and the continuous illumination of the lamp beads, heat is absorbed and diffused outward by the heat sink 4 on the upper and lower sides. In addition to absorbing heat, this arrangement can also increase the heat dissipation area through the heat sink 4. Furthermore, when the heat sink 4 diffuses the absorbed heat outward, the heat is further dissipated by the cooling fan 5, thereby allowing the heat stored inside this invention to be discharged more quickly.

[0026] With the above structure, it should be further explained that the slot provided in the first outer shell 1 is used to provide the installation of the reflector cup 3. This setting can facilitate the replacement of the reflector cup 3 by reducing the disassembly of the first outer shell 1 and the second outer shell 2, thereby achieving a quicker replacement. In addition, during the installation process, the reflector cup 3 is fixed to the edge of the slot in the first outer shell 1 with screws.

[0027] The copper substrate 8 used in this invention is used to connect the embedded LED beads to an external power source.

[0028] On the same surface where the slot is provided in the first outer shell 1, and on the adjacent side, a plurality of heat dissipation holes 11 are provided, and the plurality of heat dissipation holes 11 respectively penetrate into the first outer shell 1; at least two limiting protrusions 14 are provided on the annulus of the first outer shell 1 and on one edge away from the two protrusions.

[0029] With the above structure, it should be further explained that several heat dissipation holes 11 are used to provide heat dissipation and facilitate the heat dissipation of the cooling fan 5 and the heat sink assembly 4.

[0030] The ring connecting the two protruding pillars is used to fix the lens 71 to the fixed frame 7. With the above structure, the lens 71 can be placed at the focal point of the light refraction of the reflector cup 3, thereby avoiding the light refraction angle of the reflector cup 3 not being able to converge and then be concentrated to the lens 71 and projected outward.

[0031] The two limiting protrusions 14 of the ring are used to clamp the edge of the lens 71, to prevent the lens 71 from shaking in the fixed frame 7, and to further provide convenient fixation for installation.

[0032] The second outer shell 2 has several heat dissipation grooves 21 on its surface; a number of heat dissipation holes 11 are provided on the surface of the second outer shell 2 and on the side adjacent to the heat dissipation grooves 21; one end of the second outer shell 2 is flush with the first outer shell 1, and the other end of the second outer shell 2 extends to the two protruding pillars of the first outer shell 1.

[0033] With the above structure, it should be further explained that the second outer shell 2 has several heat dissipation grooves 21 for providing further heat dissipation.

[0034] The first outer shell 1 and the second outer shell 2 face one end of the two protruding pillars and are respectively provided with an inwardly recessed arc-shaped groove 13; the first outer shell 1 and the second outer shell 2 face one end of the socket 6 and are provided with a fixing chuck 12 at the edge. The first outer shell 1 and the second outer shell 2 are respectively fixed to the lamp holder in the outside by the fixing chuck 12.

[0035] With the above structure, it should be further explained that the arc-shaped slots 13 formed by the first outer shell 1 and the second outer shell 2 are used to intercept and compress the light, so that the diffused light is directed towards a horizontal plane and the direction of refraction of the reflector cup 3, thereby further reducing the messy projection of the light.

[0036] The reflector cup 3 is arc-shaped, and the arc-shaped opening of the reflector cup 3 faces the ring where the copper substrate 8 and the first outer shell 1 are located; a lamp bead is provided below the arc-shaped opening of the reflector cup 3, and the lamp bead is fixed to the surface of the copper substrate 8.

[0037] With the above structure, it should be further explained that the arc-shaped reflector 3 can refract light.

[0038] Each heat sink assembly 4 is composed of a horizontal plate and several vertical plates, and is set as a whole; the several vertical plates of each heat sink assembly 4 are arranged sequentially above the horizontal plate, and the side of the several vertical plates away from the horizontal plate faces the first outer shell 1 and the second outer shell 2 respectively.

[0039] With the above structure, it should be further explained that the vertical plates of the heat sink assembly 4 can increase the heat dissipation area, allowing each vertical plate to diffuse heat outwards, while the horizontal plate is in close contact with the outside of the copper substrate 8, allowing the heat of the copper substrate 8 to be directly absorbed by the horizontal plate.

[0040] The heat sink assembly 4 of this invention is made of aluminum metal. Aluminum metal has a good heat dissipation effect and is relatively lightweight, thus avoiding a certain weight load on this invention.

[0041] The cooling fan 5 is connected to the copper substrate 8 by an electrical conduit. The exhaust port of the cooling fan 5 is opposite to the two heat sink groups 4. An adapter plate 10 is placed on the side of the cooling fan 5 opposite to the two heat sink groups 4. The side of the adapter plate 10 away from the cooling fan 5 is connected to the socket 6.

[0042] With the above structure, it should be further explained that the adapter plate 10 is used to support the base of the cooling fan 5. The adapter plate 10 is made of a relatively rigid material, such as fiberglass. The adapter plate 10 made of rigid material can support the cooling fan 5 and prevent it from deforming due to heat, which would result in insufficient fixation of the cooling fan 5. This would avoid affecting the first outer shell 1 and the second outer shell 2, as well as external equipment.

[0043] The socket 6 is fixed to one end of the first housing 1 and the second housing 2, and is clamped and fixed by one end of the first housing 1 and the second housing 2; the side of the socket 6 away from the cooling fan is exposed outside the first housing 1 and the second housing 2; the side of the socket 6 facing outward is provided with at least two outwardly extending plugs 61.

[0044] With the above structure, it should be further explained that the socket 6 is used to connect to an external power supply and control unit, and the control unit includes computers and other devices that control the start and stop and power connection.

[0045] The connection of the socket 6 is achieved by inserting two plug rods 61 into the external socket, thereby realizing the electrical connection. The power inside the socket is transmitted to the socket 6 through the two plug rods 61, and then transmitted to the copper substrate 8 through the socket 6.

[0046] A lens 71 is held between the ring and the fixed frame 7 of the first outer shell 1; a placement groove is provided on the inner side of the fixed frame 7 and the side facing the ring, and the lens 71 is placed in the placement groove of the fixed frame 7; a through hole is provided in the placement groove of the fixed frame 7, one side of the lens 71 is arc-shaped and protrudes outward, and the arc-shaped convex surface of the lens 71 is embedded in the through hole of the fixed frame 7.

[0047] 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.
