[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The core of the utility model is to provide a heat dissipation vehicle lamp module and a vehicle, which can effectively improve the heat dissipation efficiency of the vehicle lamp module.

[0037] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] Specifically, please refer to Figure 1-Figure 7 The utility model provides a high-efficiency heat dissipation vehicle lamp module with an internal air guide structure 110, including an optical structure 100, an LED circuit board 200 and a heat sink 300 connected in sequence, that is, the optical structure 100 is arranged on one side of the LED circuit board 200, and the heat sink 300 is arranged on the other side.

[0039] The optical structure 100 is an optical component used to adjust and control the light distribution of the light source 210. It optimizes the lighting effect and improves the efficiency of light utilization through the principles of refraction and reflection, such as a reflector. In the headlight mold, the optical structure 100 is mainly responsible for realizing secondary optical light distribution to meet the lighting needs of different occasions.

[0040] The LED circuit board 200 is mainly used to control and drive the (LED) light source 210. Specifically, it can be regarded as a module on a microcomputer or integrated circuit, which can process the signal of the driver's control switch and instruct the switch action of the vehicle headlight module accordingly. The LED circuit board 200 body is provided with a light source area, and the power consumed by the LED light source 210 can almost be converted into light and heat. The heat of the headlight module mainly comes from the heat generated by the (LED) light source 210.

[0041] The heat sink 300 is used to dissipate heat from the LED circuit board 200 , and may specifically be a heat dissipation fan or other equipment that can provide active heat dissipation.

[0042] The optical structure 100 is provided with at least one air guide structure 110 on the side facing the LED circuit board 200. The air guide structure 110 is used to guide the external airflow to the light source area on the LED circuit board 200, thereby accelerating the air flow in the light source area, thereby reducing the operating temperature of the vehicle lamp module. At the same time, the heat sink 300 is used to dissipate heat from the LED circuit board 200.

[0043] The high-efficiency heat dissipation vehicle lamp module provided by this solution has an optical structure 100 and a heat sink 300 respectively arranged on both sides of the LED circuit board 200. By arranging a wind guide structure 110 on the side of the optical structure 100 facing the LED circuit board 200, the external natural wind is guided to flow to the light source area. At the same time, the heat sink 300 is used to dissipate heat from the light source area, thereby increasing the air circulation rate in the light source area, accelerating heat transfer, and thus reducing the temperature of the light source area. This effectively solves the problem of low heat dissipation efficiency of vehicle lamp modules in the prior art.

[0044] In a specific embodiment, when the heat sink 300 is a cooling fan, the wind flow generated during the operation of the cooling fan can flow toward the light source area under the guidance of the wind guide structure 110, further accelerating the air flow in the light source area.

[0045] In a first specific embodiment, Figure 1 , Figure 2 and Figure 5 As shown, the heat dissipation lamp module is a narrow module, the optical structure 100 is a reflective bowl, and the air guide structure 110 is arranged on the side of the reflective bowl facing the LED circuit board 200 .

[0046] Furthermore, the air guide structure 110 includes a plurality of strip plates, which are arranged at intervals and extend in the same direction, and an air inlet channel is formed between two adjacent strip plates, and the outlet of the air inlet channel is close to the light source area. The air guide structure 110 dissipates heat on the side of the LED circuit board 200 where the light source 210 is arranged, and the heat sink 300 dissipates heat on the other side of the LED circuit board 200. Through the joint action of the air guide structure 110 and the heat sink 300, the heat dissipation efficiency of the LED circuit board 200 can be effectively improved, so that there is no need to increase the size of the heat sink 300 to meet the heat dissipation requirements.

[0047] In the second specific embodiment, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the heat dissipation lamp module is a matrix module, the optical structure 100 includes an optical component 130 located in the middle and optical brackets 120 located on both sides of the optical component 130, and the wind guide structure 110 is arranged on the optical bracket 120 close to the side of the LED circuit board 200.

[0048] Furthermore, the air guide structure 110 includes at least two strip plates, an air inlet channel is formed between two adjacent strip plates, the air inlet channel is a tapering channel in the air inlet direction, and the outlet of the air inlet channel is close to the light source area.

[0049] In order to better guide the gas flow, the inner wall of the reflective bowl / optical bracket 120 is a concave arc surface, similar to a petal shape, and the outer edge of the reflective bowl / optical bracket 120 protrudes from the outer edges of the heat sink 300 and the LED circuit board 200, so as to block the airflow and guide it to the light source area of ​​the LED circuit board 200, such as Figure 6 Air flow direction A is shown.

[0050] In order to improve the structural strength, the wind guide structure 110 and the optical structure 100 are preferably an integrally formed structure, such as made by a casting process or welded. Of course, the wind guide structure 110 and the optical structure 100 can also be connected by bolts to form a built-in air duct.

[0051] The LED circuit board 200 and the heat sink 300 are connected as one by glue binding. This connection method requires that the diluted glue is put into a dipping bucket, and then the LED circuit board 200 is vertically immersed in the paint tank. During the operation, it is necessary to avoid immersing the LED circuit board 200 too quickly to avoid bubbles, so that the LED circuit board 200 can be better connected to the heat sink 300. The glued LED circuit board 200 and the heat sink 300 are connected to the optical structure 100 by fasteners.

[0052] like Figure 1 or Figure 2 As shown, the fasteners are bolts and nuts, and through holes are provided at the outer edges of the heat sink 300 and the optical structure 100 at relative positions, and the two are fastened together by bolts and nuts.

[0053] In addition, the present solution further includes a lens 500 and a lens holder 400 , wherein one end of the lens holder 400 is connected to the lens 500 , and the other end of the lens holder 400 is connected to the optical structure 100 .

[0054] like Figure 1 In the narrow-shaped headlight module shown, the optical structure 100 is a reflective bowl, and the wind guide structure 110 is located on the back of the reflective bowl. The wind guide structure 110 and the reflective bowl are an integrally formed structure. An angle is formed between the axis of the end face of one end of the lens bracket 400 and the axis of the end face of the other end of the lens bracket 400. The angle can be 90° or other angle values. By reversing the lens 500, the entire headlight module can be further thinned in the thickness direction.

[0055] Of course, you can also Figure 2 The conventional (i.e. rectangular) headlight module shown in the figure has an optical structure 100 including an optical bracket 120 on the left, an optical component 130 in the middle and an optical bracket 120 on the right. The back of the optical bracket 120 on the right is provided with a wind guide structure 110. The axis of one end face of the lens bracket 400 is coaxially arranged with the axis of the other end face of the lens bracket 400. Figure 1 The narrow headlight module is relatively thick.

[0056] The type of vehicle light module can be adaptively selected according to actual needs, and no further limitation is made here.

[0057] The high-efficiency heat dissipation lamp module provided in this case can be used for front headlights and rear headlights. In particular, the front headlights, as the only lighting fixtures in the car, require extremely strong light sources 210 to help the driver see the road ahead, and thus have particularly high heat dissipation requirements.

[0058] In addition, the utility model also provides a vehicle, including the high-efficiency heat dissipation lamp module in the above specific embodiment.

[0059] Obviously, the vehicle including the above-mentioned high-efficiency heat dissipation lamp module has the same beneficial effects, which will not be described in detail here.
