[0040] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0041] Vehicle lights are essential lighting equipment for vehicles, used to illuminate the road, indicate the vehicle's driving status, and ensure driving safety. The light patterns produced by vehicle lights must meet regulatory requirements.

[0042] During the use of vehicle lights, the heat sink inside the lights dissipates the heat generated during operation into the surrounding air, preventing the lights from being damaged due to overheating.

[0043] However, because the heat sink fins are relatively thin, they are more prone to deformation during transportation and installation, which reduces the gap between adjacent fins and decreases the heat dissipation effect, thus reducing the overall heat dissipation performance of the radiator.

[0044] To address the aforementioned technical problem of reduced heat dissipation efficiency in radiators, this application provides a lighting device. Please refer to [link / reference needed]. Figure 1 The lighting device includes a substrate 100 and a plurality of heat sinks 200; each heat sink 200 includes a base 210 and a connecting portion 220, the base 210 being connected to the substrate 100, and the connecting portion 220 being connected to the side of the base 210 away from the substrate 100; wherein, in two adjacent heat sinks 200, the base 210 of one is spaced apart from the base 210 of the other, and the connecting portion 220 of one is connected to the other.

[0045] In some embodiments, the base 210 is welded to the substrate 100.

[0046] In some embodiments, the heat sink 200 is a sheet metal part, and the connecting part 220 and the base 210 are formed by bending different parts of the same thin sheet.

[0047] In some embodiments, please refer to Figure 2 The heat sink 200 also includes a bent portion 240, which is located on the side of the base 210 close to the substrate 100. The bent portion 240 and the base 210 are formed by bending different parts of the same thin plate. The bent portion 240 is attached to and welded to the substrate 100.

[0048] It is understandable that the side of the base 210 closest to the substrate 100 is connected to the substrate 100, and the degree of freedom of the side of the base 210 closest to the substrate 100 is restricted. After the heat sink 200 is touched or bumped, the side of the base 210 closer to the substrate 100 is less likely to deform, and the side of the base 210 further away from the substrate 100 is more likely to deform.

[0049] In some embodiments, the heat sink 200 is connected to one side of the substrate 100 along the third direction Z, which intersects with the first direction X. The third direction Z is the direction of the arrow Z in the figure.

[0050] In the above embodiment, by providing a connecting portion 220 that can connect to adjacent heat sinks 200 on the side of the heat sink 200 away from the substrate 100, multiple heat sinks 200 can support each other on the side away from the substrate 100, thereby reducing the possibility of deformation of the heat sink 200 on the side away from the substrate 100, and thus reducing the possibility of reduced heat dissipation effect of the heat sink 10. In addition, since the connecting portion 220 better restricts the gap between the bases 210 of adjacent heat sinks 200, the heat sink 10 is more reliable, thereby allowing the bases 210 of the heat sink 200 to have a smaller size in the first direction X, and thus allowing the heat sink 10 to provide more heat sinks 200 in the first direction X, thereby increasing the density of heat sinks 200 and improving the heat dissipation effect of the heat sink 10, wherein the first direction X is the direction of arrow X in the figure.

[0051] In some embodiments, please refer to Figure 2 In two adjacent heat sinks 200, the connecting portion 220 of one is connected to the base portion 210 of the other on the side away from the substrate 100.

[0052] Specifically, the two heat sinks 200 arranged consecutively are a first heat sink 250 and a second heat sink 260. The base 210 of the first heat sink 250 is disposed between the substrate 100 and the connection portion 220 of the first heat sink 250, and is connected to the substrate 100 and the connection portion 220 of the first heat sink 250 respectively. The base 210 of the second heat sink 260 is disposed between the substrate 100 and the connection portion 220 of the first heat sink 250, and is connected to the substrate 100 and the connection portion 220 of the first heat sink 250 respectively.

[0053] In the above embodiment, the base 210 of adjacent heat sinks 200 are simultaneously connected to the connecting portion 220 of one of them, so that the connecting portion 220 can limit the distance between the bases 210 of adjacent heat sinks 200, reduce the possibility that the gap between the bases 210 of adjacent heat sinks 200 will become larger or smaller due to being bumped, thereby reducing the risk of the heat sink 10's heat dissipation effect being reduced during transportation and installation.

[0054] In some embodiments, please refer to Figure 2 and Figure 3 The connecting part 220 has a groove 221; in two adjacent connecting parts 220, a portion of one is disposed in the groove 221 of the other.

[0055] In some embodiments, the heat sink 200 is disposed along a first direction X, and the opening of the groove 221 is located on one side of the connection portion 220 along the first direction X; in other embodiments, the opening of the groove 221 is located on the side of the connection portion 220 facing away from or towards the substrate 100.

[0056] In the above embodiment, a portion of the connecting portion 220 can be disposed inside the groove 221 of the adjacent connecting portion 220, which can improve the connection stability of the two adjacent connecting portions 220 and further reduce the risk that the heat sink 200 will deform on the side away from the substrate 100, thereby reducing the heat dissipation effect of the heat sink 10.

[0057] In some embodiments, please refer to Figure 2 and Figure 3 The heat sink 200 also includes a limiting part 230, which is connected to the side of the base 210 near the connecting part 220. The base 210 is located in the groove 221. In two adjacent heat sinks 200, the limiting part 230 of one is disposed in the groove 221 of the other.

[0058] In some embodiments, the connecting portion 220 has a second groove wall 226 for forming a groove 221. The second groove wall 226 is spaced apart from the limiting portion 230 along the first direction X. In two adjacent heat sinks 200, the limiting portion 230 of one is disposed in the groove 221 of the other and is located between the limiting portion 230 and the second groove wall 226 of the other along the first direction X. The limiting portion 230 can be connected to the second groove wall 226 to limit the side of the two adjacent heat sinks 200 away from the substrate 100 to move away from each other along the first direction X, thereby limiting the maximum gap between the bases 210 of the two adjacent heat sinks 200.

[0059] In the above embodiment, the limiting portion 230 of one of the two adjacent heat sinks 200 is disposed in the groove 221 of the other, which can limit the relative movement of the two adjacent heat sinks 200 in the first direction X and the second direction Y by contacting the groove wall of the groove 221, thereby maintaining the gap between the bases 210 of the adjacent heat sinks 200 and reducing the risk of reduced heat dissipation effect of the heat sink 10 during transportation and installation.

[0060] In some embodiments, the second direction Y is the direction of arrow Y in the figure, and the first direction X, the second direction Y and the third direction Z intersect each other.

[0061] In some embodiments, please refer to Figure 2 and Figure 3 The bases 210 of adjacent heat sinks 200 are spaced apart along the first direction X. The connecting portion 220 includes a first connecting portion 222 and a second connecting portion 223. The first connecting portion 222 is connected to the side of the base 210 away from the substrate 100, and the first connecting portion 222 has a groove 221 along the first direction X. The second connecting portion 223 is connected to the side of the first connecting portion 222 away from the groove 221 along the first direction X. In two adjacent connecting portions 220, the second connecting portion 223 of one is disposed in the groove 221 of the other.

[0062] In some embodiments, in adjacent heat sinks 200, the first bonding portion 222 of one is connected to the base portion 210 of the other on the side away from the substrate 100.

[0063] In the above embodiment, the end of the second bonding portion 223 that is away from the first bonding portion 222 along the first direction X can abut against other heat sinks 200 to limit the minimum size of the gap between the base 210 and the base 210 of the abutting heat sink 200, thereby reducing the risk that the heat dissipation effect of the heat sink 10 will be reduced due to the smaller gap between the bases 210.

[0064] In some embodiments, the second coupling portion 223 can abut against the second groove wall 226, thereby limiting the minimum dimension between the bases 210 of two adjacent heat sinks 200.

[0065] In some embodiments, please refer to Figure 2 and Figure 11 The three heat sinks 200 arranged consecutively are a first heat sink 250, a second heat sink 260, and a third heat sink 270. The base 210 of the second heat sink 260 is disposed between the base 210 of the first heat sink 250 and the base 210 of the third heat sink 270 along the first direction X. The second heat sink 260 is located on the side of the first connecting part 222 of the first heat sink 250 near the second connecting part 223. The second connecting part 223 of the first heat sink 250 is disposed in the groove 221 of the second heat sink 260, and the limiting part 230 of the third heat sink 270 is disposed in the groove 221 of the second heat sink 260. The limiting part 230 of the third heat sink 270 is disposed between the second connecting part 223 of the first heat sink 250 and the second groove wall 226 of the second heat sink 260 along the first direction X.

[0066] In the above embodiment, the second connecting part 223 of the first heat sink 250 can abut against the limiting part 230 of the third heat sink 270 to limit the minimum size of the gap between the base 210 of the first heat sink 250 and the base 210 of the third heat sink 270. That is, the spaced heat sinks 200 can also support each other to further reduce the possibility of gap changes between the bases 210 of the multiple heat sinks 200, and reduce the possibility of reduced heat dissipation effect of the radiator 10.

[0067] In some embodiments, please refer to Figure 4 In two adjacent connecting portions 220, the base 210 of one is located between the base 210 of the other and the portion of the second connecting portion 223 along the first direction X.

[0068] In some embodiments, please refer to Figure 5The second bonding portion 223 protrudes toward the substrate 100 such that at least a portion of the second bonding portion 223 can be located on one side of the base 210 of the other along the first direction X.

[0069] In some embodiments, the side of the second bonding portion 223 away from the first bonding portion 222 is inclined toward the substrate 100, such that at least a portion of the second bonding portion 223 can be located on the side of the base 210 of the other along the first direction X.

[0070] In some embodiments, the base 210 of one is located along a first direction X between the base 210 of the other and the portion of the second bonding sub-part 223 near the substrate 100.

[0071] In the above embodiment, the second connecting part 223 of the heat sink 200 can hook the base 210 of the adjacent heat sink 200 to limit the mutual movement of the adjacent heat sinks 200 away from each other along the first direction X, thereby limiting the maximum size of the gap between the bases 210 of the two adjacent heat sinks 200, thereby reducing the possibility of the heat sink 200 deforming after being subjected to force, and reducing the risk of the heat dissipation effect of the radiator 10 decreasing.

[0072] In some embodiments, please refer to Figure 4 At least a portion of the second connecting part 223 is disposed between two adjacent bases 210 along the first direction X, and is connected to the two adjacent bases 210 respectively.

[0073] Specifically, please refer to Figure 11 The three heat sinks 200 arranged consecutively are a first heat sink 250, a second heat sink 260, and a third heat sink 270. The base 210 of the second heat sink 260 is disposed between the base 210 of the first heat sink 250 and the base 210 of the third heat sink 270 along the first direction X. The second heat sink 260 is located on the side of the first connecting part 222 of the first heat sink 250 close to the second connecting part 223. The second connecting part 223 of the first heat sink 250 is disposed between the base 210 of the second heat sink 260 and the base 210 of the third heat sink 270 along the first direction X. The second connecting part 223 of the first heat sink 250 abuts against the base 210 of the second heat sink 260 and the base 210 of the third heat sink 270 along the first direction X, thereby limiting the minimum size of the base 210 of the second heat sink 260 and the base 210 of the third heat sink 270 along the first direction X.

[0074] In other words, the dimension of the second connecting part 223 along the first direction X is the minimum dimension of the gap between the bases 210 of the adjacent heat sinks 200 along the first direction X.

[0075] In the above embodiment, by having the second connecting part 223 disposed between the bases 210 of two adjacent heat sinks 200 along the first direction X, and connecting the bases 210 of the two adjacent heat sinks 200 respectively to limit the minimum size of the gap between the two adjacent bases 210 along the first direction X, the possibility of the heat sink 200 deforming under force is reduced, thereby reducing the risk of the heat dissipation effect of the radiator 10 decreasing.

[0076] In some embodiments, please refer to Figure 3 and Figure 5 The first connecting part 222 has a first guide surface 224 and a second guide surface 225 for surrounding the groove 221. The second connecting part 223 is disposed between the first guide surface 224 and the second guide surface 225 along the second direction Y and connects the first guide surface 224 and the second guide surface 225 respectively. The first direction X and the second direction Y intersect. The distance between the first guide surface 224 and the second guide surface 225 along the second direction Y gradually decreases from the first connecting part 222 towards the second connecting part 223.

[0077] In some embodiments, the second bonding portion 223 decreases in size along the second direction Y in a direction away from the first bonding portion 222.

[0078] In some embodiments, the first guide surface 224 is one of a plane and an arc surface or a combination of a flat surface and an arc surface; in some embodiments, the second guide surface 225 is one of a plane and an arc surface or a combination of a flat surface and an arc surface.

[0079] In the above embodiment, by setting the first guide surface 224 and the second guide surface 225, when the second connecting part 223 enters the groove 221 along the first direction X, it can automatically center itself by contacting the first guide surface 224 and the second guide surface 225, so as to realize the positioning of the heat sink 200 along the second direction Y during the installation process, thereby reducing the assembly difficulty of the heat sink 10.

[0080] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 5 The base 210 has a receiving groove 211 on the side away from the substrate 100. The receiving groove 211 has a first groove wall 212 facing away from the substrate 100. The connecting part 220 is disposed in the receiving groove 211 and connected to the first groove wall 212.

[0081] In the above embodiment, the connection portion 220 is disposed in the receiving groove 211, which reduces the degree to which the connection portion 220 protrudes from the base 210, thereby reducing the possibility of the connection portion 220 scratching the operator. At the same time, by reducing the degree to which the connection portion 220 protrudes from the base 210, the possibility of the connection portion 220 being touched and causing the connection portions 220 of adjacent heat sinks 200 to separate can also be avoided, thus improving the reliability of the heat sink 10.

[0082] In some embodiments, please refer to Figure 1 and Figure 6 The lighting device also includes a light-emitting component 20, a first lens 30, a bracket 40, and a second lens 50. The light-emitting component 20 is connected to the side of the substrate 100 away from the heat sink 200. The first lens 30 is connected to the side of the light-emitting component 20 away from the heat sink 10. The bracket 40 is connected to the side of the heat sink 10 close to the light-emitting component 20. The second lens 50 is connected to the end of the bracket 40 away from the heat sink 10.

[0083] Please refer to Figure 7 and Figure 8 A positioning post 51 is provided on the side of the second lens 50 near the bracket 40, and a positioning groove 41 is provided on the side of the bracket 40 near the second lens 50. The positioning post 51 is located in the positioning groove 41 to restrict the relative movement of a part of the second lens 50 and the bracket 40 when connecting the second lens 50 and the bracket 40, thereby reducing the assembly difficulty of the lighting device.

[0084] In some embodiments, the second lens 50 and the bracket 40 are welded together. In some embodiments, the second lens 50 and the bracket 40 are laser welded together to improve assembly accuracy and connection reliability.

[0085] In some embodiments, please refer to Figure 7 The bracket 40 has a first surface 42 facing the second lens 50. A positioning groove 41 is disposed on the first surface 42. The first surface 42 is provided with a first protrusion 43 and a second protrusion 44, which are spaced apart along the circumference of the second lens 50.

[0086] In the above embodiment, when the second lens 50 is welded to the bracket 40, the laser passes through the transparent second lens 50 and irradiates the first protrusion 43. The welding is completed when the laser moves along the circumference of the second lens 50 to the second protrusion 44. The first protrusion 43 and the second protrusion 44 reduce the difficulty of the welding process and improve the assembly efficiency of the lighting device.

[0087] In some embodiments, please refer to Figure 8 and Figure 9The bracket 40 has a first receiving cavity 45. The light emitted from the light-emitting component 20 passes through the first lens 30 and then through the first receiving cavity 45 to the second lens 50. The lighting device also includes a heat insulation component 60, which is disposed in the first receiving cavity 45 and connected to the bracket 40. The heat insulation component 60 has a second receiving cavity 61, through which the light emitted from the first lens 30 passes to the second receiving cavity 61 and then to the second lens 50.

[0088] In the above embodiment, by providing a heat insulation component 60, the possibility of sunlight shining through the second lens 50 onto the inner wall of the bracket 40 is reduced, the possibility of sunlight over-focusing inside the bracket 40 and damaging the bracket 40 is reduced, and the reliability of the lighting device is improved.

[0089] In some embodiments, a thermally conductive adhesive is coated between the substrate 100 and the light-emitting component 20 to improve the heat transfer efficiency between the light-emitting component 20 and the heat sink 10.

[0090] In some embodiments, please refer to Figure 6 The substrate 100 has an overflow groove on the side facing the light-emitting component 20 so that excess thermally conductive adhesive can overflow when assembling the lighting device, reducing the possibility that the thermally conductive adhesive will cause the light-emitting component 20 to move away from the heat sink 10.

[0091] In some embodiments, please refer to Figure 10 The light-emitting component 20 and the substrate 100 are connected by a connector 21; in some embodiments, the connector 21 is a screw.

[0092] Accordingly, this application also provides a vehicle including a lighting device as described in any of the above embodiments.
