[0002] A car light is a device that can be used for lighting or outputting information. Taking a vehicle headlight as an example, it needs to maintain high power output for a long time, so a radiator is needed to dissipate heat to ensure normal operation.

[0003] As a vehicle headlamp, it needs to project a low beam zone III light shape. Generally, the low beam zone III structure of the headlight is designed on the light incident surface of the lens, for example, it is set in the form of a small boss, so that the light is refracted at the light incident surface of the lens, and when the low beam light shape is formed on the light distribution screen, the low beam zone III structure can make the light form a low-energy light spot above the HV axis of the light distribution screen. This is the low beam zone III light shape, which meets the low beam regulatory requirements.

[0004] However, making a low beam zone III structure on the light incident surface of the lens will occupy the area of the light incident surface, which is not conducive to the light efficiency of the low beam light shape. In addition, the production of the lens mold is relatively complicated, and the accuracy of the lens and the low beam zone III structure needs to be ensured, which requires high manufacturing accuracy of the lens. In addition, making a low beam zone III structure on the light incident surface of the lens also makes the appearance of the lens unsightly.

[0042] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the specific embodiments described below.

[0043] It should be noted that the front, back, left, right, up and down in this article are all determined with the vehicle as the reference system.

[0044] like Figure 1 and Figure 2 As shown, the utility model provides a heat sink for use in conjunction with a circuit board 4 provided with a light source, a reflector 1 and a lens 2. The heat sink includes a receiving portion 3, the circuit board 4 is connected to the receiving portion 3, and a reflecting portion 31 is provided at the side of the receiving portion 3 close to the lens 2. The side of the reflecting portion 31 facing the lens 2 is a reflecting surface. The light source includes a low beam light source. A portion of the light emitted by the low beam light source is reflected by the reflector 1 and emitted toward the lens 2 to form a low beam light shape. Another portion of the light emitted by the low beam light source is reflected by the reflector 1 and emitted toward the reflecting portion 31, and is reflected toward the lens 2 by the reflecting surface of the reflecting portion 31 to form a low beam zone III light shape after being emitted through the lens 2.

[0045] Based on the above technical solution, on the one hand, the radiator is connected to the circuit board 4 provided with a light source, and can conduct the heat generated by the light source to achieve heat dissipation. On the other hand, the reflecting portion 31 formed on the radiator can reflect a portion of the light emitted by the low beam light source, so that this portion of the light can be directed toward the lens 2 and emitted through the lens 2 to form a low beam zone III light shape, so that the reflecting portion 31 can be used as a low beam zone III structure, and then there is no need to set a corresponding low beam zone III structure on the lens 2, which can simplify the structure of the lens 2, reduce the manufacturing difficulty and manufacturing cost of the lens 2, and make the appearance of the lens 2 more beautiful.

[0046] like Figure 1 and Figure 3 As shown, a heat dissipation surface 32 is further provided at the side of the receiving portion 3 where the reflecting portion is not provided. For example, a pair of heat dissipation surfaces 32 can be provided on the left and right sides of the receiving portion 3, and a hollow ventilation structure 321 is provided on the heat dissipation surface 32. The hollow ventilation structure 321 can be a through hole or a through groove, so that air can pass through the hollow ventilation structure 321 to form air circulation, thereby improving the heat dissipation effect, and the hollow ventilation structure 321 can be preferably set as a through groove, which can extend along the front-to-back direction or along the up-and-down height direction, and the more through grooves are provided, the larger the area available for heat dissipation, thereby achieving a better heat dissipation effect, for example, Figure 3 As shown, a plurality of through slots extending in the vertical direction can be arranged in the front-to-back direction, which can increase the area of the heat dissipation surface 32 by 1 / 3 and improve the heat dissipation efficiency by 4%-8%.

[0047] In addition, if Figure 5 and Figure 6 As shown, the light source also includes a high-beam light source, and the low-beam light source and the high-beam light source are both arranged on the circuit board 4 and can be connected to the receiving part 3 via the circuit board 4. The light emitted by the high-beam light source is reflected by the reflector 1 and then emitted to the lens 2 to form a high-beam light shape. It can be understood that the low-beam light source and the high-beam light source can be arranged on the same circuit board 4 or different circuit boards, that is, the low-beam light source and the high-beam light source can be arranged on the same surface or different surfaces of the receiving part 3, and the low-beam light source and the high-beam light source can be arranged on the same surface of the receiving part 3 as a preference, that is, the low-beam light source and the high-beam light source can be arranged on the same circuit board 4, which saves costs on the one hand, and on the other hand, the circuit board 4 and the reflector 1 are both one-piece molded structures with higher strength, and during installation, the circuit board 4 can be installed between the reflector 1 and the radiator, and the installation structure composed of the three is more compact.

[0048] It is understandable that if Figure 1 and Figure 3 As shown, a groove 34 suitable for accommodating thermally conductive adhesive is provided on the side of the receiving portion 3 that is connected to the circuit board 4. The position of the groove 34 corresponds to the position of the high-beam light source and / or the low-beam light source. Since the high-beam light source generates more heat, the groove 34 can preferably be positioned at least corresponding to the position of the high-beam light source to at least ensure the heat dissipation of the high-beam light source. When installing the circuit board 4, the thermally conductive adhesive can be first filled into the groove 34, and then the circuit board 4 and the receiving portion 3 are superimposed, so that the circuit board 4 and the receiving portion 3 can be temporarily fixed by gluing. The thermally conductive adhesive can fill the gap between the circuit board 4 and the receiving portion 3, so that there is basically no air layer between the circuit board 4 and the receiving portion 3, thereby improving the heat exchange efficiency between the circuit board 4 and the receiving portion 3, and thus improving the heat dissipation effect.

[0049] Specifically, if Figure 2 and Figure 6 As shown, when the circuit board 4 is connected to the upper surface of the receiving portion 3, the heat sink can be set to gradually tilt upward from the back to the front, and as shown in FIG. Figure 4 As shown, a light-transmitting port 33 is provided on the receiving portion 3, so that the light emitted by the high-beam light source is reflected by the reflector 1, passes through the light-transmitting port 33 and is emitted from the area below the reflecting portion 31 toward the lens 2, and is emitted through the lens 2 to form a high-beam light shape, thereby enabling the formation of the high-beam light shape to be free from interference from the formation of the low-beam light shape, and the optical paths of the two are independent of each other.

[0050] It is understandable that if Figure 4As shown, an auxiliary heat sink 331 can be set at the edge of the light-transmitting opening 33 to further improve the heat dissipation of the high-beam light source, and the auxiliary heat sink 331 should be set on the left and right sides or the rear side of the light-transmitting opening 33 so as not to affect the propagation of light emitted by the high-beam light source.

[0051] The structure and manufacturing method of the radiator will be described below using a preferred embodiment:

[0052] Specifically, the radiator is an aluminum plate, and its main part is a receiving part 3, which is used to connect with the light source and the reflector 1. A reflecting part 31 that is tilted and bent downward is provided on the front side of the receiving part 3, and auxiliary heat dissipation surfaces 32 that are tilted and bent downward are provided on the left and right sides of the receiving part 3. A number of through grooves are provided on the heat dissipation surface 32 to serve as a hollow ventilation structure 321. A groove 34 is provided on the upper surface of the receiving part 3 at a position corresponding to the high beam light source, and two light-transmitting openings 33 are also provided on the receiving part 3. Auxiliary heat dissipation plates 331 are provided at the left edge of the light-transmitting opening 33 on the left and the right edge of the light-transmitting opening 33 on the right.

[0053] When manufacturing the radiator, a plate of a set shape can be punched out on an aluminum plate first. The plate includes a main body and three extended edges located on the front side and left and right sides of the main body, wherein the main body serves as the receiving part 3 of the radiator. Then, the extended edges on the left and right sides can be punched out to form a number of through grooves as a hollow ventilation structure 321. Subsequently, the three extended edges are punched out of sheet metal, so that the extended edge on the front side is bent downward to form a reflecting part 31, and the extended edges on the left and right sides are bent downward to form an auxiliary heat dissipation surface 32. Then, a groove 34 and two C-shaped through grooves can be milled on the receiving part 3. Finally, sheet metal is punched out at the two C-shaped through grooves, so that the plate surface at the C-shaped through groove is bent downward to form an auxiliary heat dissipation plate 331. The forming method of the auxiliary heat dissipation plate 331 can make reasonable use of the plate and improve the heat distribution efficiency. Finally, the side of the reflecting part 31 facing the lens 2 is electroplated, for example, a layer of metal silver is electroplated to improve the reflectivity.

[0054] Furthermore, if Figures 10 to 12As shown, the second aspect of the present invention provides a vehicle lamp module, comprising a circuit board 4 provided with a light source, a reflector 1, a lens 2 and the radiator of the above technical solution, wherein the light source comprises a low-beam light source and a high-beam light source, and accordingly, a low-beam reflector 11 and a high-beam reflector 12 need to be provided on the reflector 1, so that a part of the light emitted by the low-beam light source is reflected by the low-beam reflector 11 toward the lens 2 to be emitted as a low-beam light shape, and the other part is reflected by the low-beam reflector 11 and then emitted to the reflecting portion 31, and is reflected by the reflecting surface of the reflecting portion 31. After reflection, it is emitted toward the lens 2, and is formed into a low beam zone III light shape after being emitted through the lens; the light emitted by the high beam light source is reflected by the high beam reflector 12 and is emitted toward the lens 2, and is formed into a high beam light shape after being emitted through the lens 2, so that the headlight module can realize the projection of high beam and low beam, and the headlight module uses the reflecting part 31 on the radiator as the low beam zone III structure, so that there is no need to set a corresponding low beam zone III structure on the lens 2, thereby simplifying the structure of the lens 2, reducing the difficulty of manufacturing the lens 2, and making the appearance of the lens 2 more beautiful.

[0055] Specifically, if Figure 7 and Figure 8 As shown, there are at least two low beam light sources, at least two low beam reflectors 11, and at least two low beam transmission units 21 are provided on the lens 2, and one low beam reflector 11 corresponds to one low beam transmission unit 21, and corresponds to one or at least two low beam light sources, there are at least two high beam light sources, at least two high beam reflectors 12 are provided, and at least two high beam transmission units 22 are also provided on the lens 2, and one high beam reflector 12 corresponds to one low beam transmission unit 21, and corresponds to one or at least two high beam light sources.

[0056] For example, Figure 9As shown, the low beam light source can be set to four, and all are located on the front side of the circuit board 4 and arranged in sequence along the left and right directions. The low beam reflector 11 is set to four, and all are located on the front side of the reflector 1 and arranged in sequence along the left and right directions. It can be understood that a corresponding low beam cut-off line structure needs to be set on the low beam reflector 11 (which is a prior art and will not be repeated here). Four low beam light units 21 are arranged in sequence on the upper part of the lens 2 along the left and right directions. The light exit surface of the lens 2 is a curved surface convex forward, and the light incident on each low beam light unit 21 The surface is a curved surface convex backward to form a biconvex lens, which is used to converge the incident light and project it forward to form a corresponding light shape, and a low-beam reflector 11 corresponds to a low-beam transmission unit 21 and corresponds to a low-beam light source, so that the low-beam reflector 11 can collimate the light emitted by the corresponding low-beam light source and then emit it to the corresponding low-beam transmission unit 21, or reflect it from the reflective surface of the reflective portion 31 on the radiator and then emit it to the corresponding low-beam transmission unit 21 to form the corresponding part of the low-beam light shape. In addition, the two middle low-beam light sources and their corresponding low-beam reflectors 11 and low-beam transmission units 21 can also be used to form a middle light shape with higher brightness of the low-beam light shape, and the low-beam light sources on both sides and their corresponding low-beam reflectors 11 and low-beam transmission units 21 can be used to form a widened light shape with a wider illumination range of the low-beam light shape.

[0057] Similarly, there are two high-beam light sources, both located on the rear side of the circuit board 4 and arranged in sequence along the left-right direction; there are two high-beam reflectors 12, both located on the rear side of the reflector 1 and arranged in sequence along the left-right direction; two high-beam light-transmitting units 22 are arranged in sequence along the left-right direction at the lower part of the lens 2; the light-emitting surface of the lens 2 is a curved surface convex forward, and the light-incident surface of each high-beam light-transmitting unit 22 is a curved surface convex backward, so as to form a double convex lens for converging the incident light and projecting it forward to form a corresponding light shape; and one high-beam reflector 12 corresponds to one high-beam light-transmitting unit 22 and to one high-beam light source, so that the high-beam reflector 12 can collimate the light emitted by the corresponding high-beam light source and then pass it through the light-transmitting port 33 from the bottom of the reflecting part 31 on the radiator to the corresponding high-beam light-transmitting unit 22 to form the corresponding part of the high-beam light shape. In addition, one of the high beam light sources and its corresponding high beam reflector 12 and high beam transmission unit 22 can be used to form a central light shape with higher brightness of the high beam light shape, and the other high beam light source and its corresponding high beam reflector 12 and high beam transmission unit 22 can be used to form a widened light shape with a wider illumination range of the high beam light shape.

[0058] like Figures 10 to 12As shown, the headlight module also includes a lens holder 5, which is provided with a light outlet 51 for configuring the lens 2. The lens holder 5 has a first clipping edge 511 and a second clipping edge 512 arranged at the edge of the light outlet 51. The outer surface of the lens holder 5 is a continuous surface. The lens holder 5 and the first clipping edge 511 and the second clipping edge 512 are formed as a whole. The edges of the lens 2 are respectively clipped with the first clipping edge 511 and the second clipping edge 512, and the first clipping edge 511 and the second clipping edge 512 respectively cover the edges of the lens 2.

[0059] Specifically, the lens holder 5 is arranged on the light-emitting side of the light source, and the upper and lower edges of the light outlet 51 of the lens holder 5 are folded inwardly to form a first snap-fit edge 511 and a second snap-fit edge 512. When the lens 2 is covered at the light outlet 51, the edge of the lens 2 is snap-fitted with the first snap-fit edge 511 and the second snap-fit edge 512. The upper and lower edges of the lens holder 5 at the light outlet 51 are folded inwardly to form a strip-shaped first snap-fit edge 511 and a second snap-fit edge 512 to form a snap-fit structure. At the same time, the outer surface of the lens holder 5 is a continuous surface, and the snap-fit structure and the lens holder 5 form a whole. And when the lens 2 is snap-fitted to the lens holder 5, the first snap-fit edge 511 and the second snap-fit edge 512 respectively cover the two opposite edges of the lens 2. When the light source passes through the lens 2, since the outer surface of the lens holder 5 is a continuous surface without a hollow structure or grooves, and the edge of the lens 2 is covered by the first clip edge 511 and the second clip edge 512, there will be no light leakage, ensuring that the light emitted by the light source is emitted through the lens 2.

[0060] Furthermore, the third aspect of the present invention provides a vehicle lamp, which includes the vehicle lamp module in the above technical solution, and therefore also has all the technical effects brought by the above vehicle lamp module.

However, the present invention is not limited to the specific details of the above embodiments.

[0062] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0063] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
