[0048] The car light is an important lighting device of the vehicle, which is used to illuminate the road and prompt the vehicle driving state, and to ensure the safety of driving. The light shape generated by the car light applied to the vehicle needs to meet the regulatory requirements.

[0049] However, the existing car light will cause stray light due to unreasonable internal structure setting, which will affect the light type generated by the light emitted by the car light and the lighting effect of the car light.

[0050] In order to solve the above technical problem of stray light caused by unreasonable internal structure setting of the car light, the first embodiment of the present application provides a lighting device, please refer to Figure 1 、 Figure 3 and Figure 9The lighting device comprises a light-emitting assembly 100, a support 400 and a first lens 200; the support 400 comprises a first connecting part 421 and a light-blocking part 440, the first connecting part 421 is connected with the light-emitting assembly 100, the light-blocking part 440 is connected with the first connecting part 421 and is arranged in a spaced manner with the light-emitting assembly 100; the first lens 200 is arranged in a spaced manner with the light-emitting assembly 100, the first lens 200 is connected with the first connecting part 421, the first lens 200 is provided with a first limiting part 220, and the first limiting part 220 is connected to one side of the light-blocking part 440 away from the light-emitting assembly 100.

[0051] In some embodiments, the first limiting part 220 is connected to one side of the light-blocking part 440 away from the light-emitting assembly 100 along the second direction Y.

[0052] It can be understood that, in some embodiments, the first limiting part 220 is integrally formed with other parts of the first lens 200, and the first limiting part 220 and the other parts are both made of a light-transmitting material. The light emitted by the light-emitting assembly 100 may enter the first limiting part 220 and form stray light after refraction, affecting the effect of the lighting device.

[0053] In some embodiments, the light-blocking part 440 is made of a non-light-transmitting material to have the effect of blocking light.

[0054] In the above embodiments, by providing the first limiting part 220 on the first lens 200 to enable the first lens 200 to be in contact with the support 400, the limiting of the first lens 200 is realized. In addition, the light-blocking part 440 made of a non-light-transmitting material is connected with the first limiting part 220 and limits the first limiting part 220 along the second direction Y, which enables the first limiting part 220 to be made of a light-transmitting material without worrying about the light emitted by the light-emitting assembly 100 forming stray light in the light-transmitting first limiting part 220, so that the first limiting part 220 and the light-transmitting part can be made by integral molding. Under the premise of reducing the number of parts of the first lens 200 and the assembly difficulty of the lighting device, the possibility of forming stray light of the lighting device is reduced, and the lighting effect of the lighting device is better. Specifically, even if the first limiting part 220 is made of a light-transmitting material, the light emitted by the light-emitting assembly 100 towards the first limiting part 220 will be blocked by the light-blocking part 440 located between the first limiting part 220 and the light-emitting assembly 100, reducing the possibility of forming stray light in the first limiting part 220.

[0055] In some embodiments, referring to Figure 12 , the first limiting part 220 and the plurality of lens parts 210 are integrally formed; the lens part 210 has a first surface 211 and a second surface 212 facing away from each other, the first surface 211 faces the light-emitting assembly 100, the first surfaces 211 of adjacent lens parts 210 are connected, and the second surfaces 212 of adjacent lens parts 210 are connected.

[0056] The light emitted by the light source 111 is emitted to the second lens 310 of the lens assembly 300, then to the first surface 211 and the second surface 212 in sequence, and is emitted out of the second surface 212.

[0057] In some embodiments, the surface of the first limiting portion 220 is provided with frosted lines to further reduce the possibility of light entering the first limiting portion 220 and producing stray light and scattered light, and to improve the effect of the lighting device.

[0058] In some embodiments, the lens portion 210 is provided with frosted lines on the side away from the first connecting portion 421 along the third direction Z to further reduce the possibility of light being emitted from the lens portion 210 on the side away from the first connecting portion 421 along the third direction Z to produce stray light and scattered light, and to improve the effect of the lighting device.

[0059] In some embodiments, the first limiting portion 220 and the lens portion 210 are made of the same material so that the first limiting portion 220 and the lens portion 210 can be made by one-piece molding.

[0060] In some embodiments, the first surface 211 protrudes in a direction away from the second surface 212; in some embodiments, the second surface 212 protrudes in a direction away from the first surface 211.

[0061] In the above embodiments, making the first limiting portion 220 and the lens portion 210 one-piece molding can improve the manufacturing efficiency of the first lens 200, reduce the number of parts of the first lens 200, and thus reduce the number of parts of the lighting device. At the same time, connecting the first surfaces 211 of adjacent lens portions 210 to each other and connecting the second surfaces 212 of adjacent lens portions 210 to each other can further reduce the size of the first lens 200 along the first direction X, and thus reduce the size of the lighting device along the first direction X.

[0063] Specifically, the lens portion 210 is configured to adjust the light emitted by the light emitting assembly 100.

[0064] In some embodiments, the light shielding portion 440 and the second limiting portion 430 are spaced apart along the second direction Y.

[0065] In some embodiments, the first limiting portion 220 is connected to the light shielding portion 440 and the first limiting portion 220, respectively.

[0066] Specifically, the light shielding portion 440 is configured to limit the movement of the first limiting portion 220 along the second direction Y towards the light emitting assembly 100, thereby limiting the movement of the first lens 200 along the second direction Y towards the light emitting assembly 100; the second limiting portion 430 is configured to limit the movement of the first limiting portion 220 along the second direction Y away from the light emitting assembly 100, thereby limiting the movement of the first lens 200 along the second direction Y away from the light emitting assembly 100.

[0067] In the above embodiments, by providing the second limiting portion 430 spaced apart from the light shielding portion 440, the first limiting portion 220 disposed in the limiting groove 410 is limited along the second direction Y, thereby limiting the movement of the first lens 200 relative to the bracket 400 along the second direction Y.

[0068] In some embodiments, the first lens 200 includes at least two first limiting portions 220, and the at least two first limiting portions 220 are disposed on both sides of the lens portion 210 along the first direction X; the bracket 400 includes at least two light shielding portions 440 and at least two second limiting portions 430, so that the first limiting portions 220 on both sides of the lens portion 210 are disposed in the limiting groove 410.

[0069] In the above embodiments, the first limiting portions 220 at both ends of the lens portion 210 along the first direction X enable the light shielding portion 440 and the second limiting portion 430 to further limit the rotation of the first lens 200 relative to the bracket 400, thereby improving the connection stability of the first limiting portion 220 and the bracket 400 and improving the use reliability of the lighting device.

[0070] In some embodiments, please refer to Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 13 and Figure 14The bracket 400 further comprises a third connecting portion 480 disposed on the side of the light shielding portion 440 close to the light emitting assembly 100. The lighting device further comprises a cover plate 500 comprising a covering portion 520 and a fourth connecting portion 510. The covering portion 520 is disposed on the side of the first lens 200 away from the first connecting portion 421. The fourth connecting portion 510 is connected to the side of the covering portion 520 close to the first connecting portion 421, and is connected to the third connecting portion 480.

[0071] In some embodiments, the third connecting portion 480 and the fourth connecting portion 510 are snap-fit connected. In some embodiments, the fourth connecting portion 510 can be inserted into the third connecting portion 480 along the third direction to be snap-fit connected to the third connecting portion 480.

[0072] In some embodiments, the covering portion 520 is disposed on the side of the first lens 200 away from the first connecting portion 421 along the third direction.

[0073] In the above embodiments, by disposing the covering portion 520 so that the first lens 200 is located in a relatively closed space, the possibility of damage to the first lens 200 is reduced, and the use reliability of the lighting device is improved. At the same time, by disposing the third connecting portion 480 and the fourth connecting portion 510 that can be connected to each other to achieve quick connection of the cover plate 500 and the bracket 400, the assembly efficiency of the lighting device is improved. At the same time, the third connecting portion 480 located on the side of the light shielding portion 440 close to the light emitting assembly 100 can also have a certain light shielding effect on the first limiting portion 220.

[0074] In some embodiments, referring to Figure 3 , Figure 5 , Figure 7 , Figure 13 and Figure 14 , the bracket 400 further comprises a second connecting portion 423 connected to the side of the first connecting portion 421 close to the first lens 200, and connected to the side of the light emitting assembly 100 close to the first lens 200. The second connecting portion 423 has a light transmission hole 424 for the light emitted by the light emitting assembly 100 to pass through.

[0075] In some embodiments, the second connecting portion 423 is connected to the side of the first connecting portion 421 close to the first lens 200 along the third direction, and is connected to the side of the light emitting assembly 100 close to the first lens 200 along the second direction Y.

[0076] Specifically, the light transmission hole 424 penetrates the second connecting portion 423 along the second direction Y, so that the light emitted by the light emitting assembly 100 can pass through the light transmission hole 424 and enter the first lens 200.

Meanwhile, the light transmission hole 424 is arranged on the second connecting portion 423 to avoid the second connecting portion 423 from blocking the light emitted by the light emitting assembly 100, so that the light emitted by the light emitting assembly 100 can still reach the first lens 200, thereby improving the connection reliability between the support 400 and the light emitting assembly 100 and ensuring the reliability of the lighting device.

[0078] In some embodiments, referring to Figure 5 , Figure 13 and Figure 14 , the support 400 comprises a spacing portion 450, the spacing portion 450 is arranged on the light transmission hole 424 and connected with the second connecting portion 423, and the spacing portion 450 divides the light transmission hole 424 into a plurality of light transmission sub-holes 425.

[0082] In the above embodiment, the supporting portion 470 is arranged to form a reinforcing rib between the first connecting portion 421 and the spacing portion 450, so as to improve the mechanical property of the support 400, reduce the possibility of relative deformation of the first connecting portion 421 and the second connecting portion 423, and improve the use reliability of the lighting device. In addition, the supporting portion 470 can play a role of light shielding, so as to reduce the mutual influence of the light passing through different light transmission sub-holes 425 to form stray light, and improve the effect of the lighting device.

[0095] In the above embodiments, the interval portion 450 is arranged to separate the light emitted by different light source groups 110, thereby reducing the possibility of the light emitted by different light source groups 110 affecting each other and forming stray light.

[0096] In some embodiments, the support portion 470 connected to the interval portion 450 can also serve to separate the light emitted by different light source groups 110.

[0097] In some embodiments, referring to Figure 5 , the lens assembly 300 includes a plurality of second lenses 310 arranged along the first direction X, and each second lens 310 is arranged between a light source 111 and the first lens 200. The light emitted by each light source 111 passes through a second lens 310 and is directed to the lens portion 210 of the first lens 200.

[0098] Specifically, the second lens 310 serves as an inner lens and is used to adjust the light emitted by the light source 111.

[0099] In some embodiments, referring to Figure 1 , Figure 5 , Figure 9 and Figure 10 , the lens assembly 300 further includes a second base 320, and the second lens 310 is fixed to the second base 320. The second base 320 is connected to the light emitting assembly 100.

[0100] In some embodiments, the second base 320 surrounds and is connected to the second lens 310. In some embodiments, the second lens 310 and the second base 320 are integrally formed.

[0101] In the above embodiments, a plurality of second lenses 310 arranged along the first direction X are arranged to match the plurality of light sources 111 arranged along the first direction X. In this way, the light emitted by each light source 111 can be adjusted by a second lens 310 before being directed to the lens portion 210 of the first lens 200.

[0102] In some embodiments, referring to Figure 15 , the plurality of light source groups 110 include a first light source group 110, a second light source group 110, and a third light source group 110. The second light source group 110 is arranged on one side of the first light source group 110 along the first direction X, and the number of light sources 111 in the second light source group 110 is greater than the number of light sources 111 in the first light source group 110. The third light source group 110 is arranged on the side of the first light source group 110 away from the second light source group 110 along the first direction X, and the number of light sources 111 in the third light source group 110 is greater than the number of light sources 111 in the first light source group 110.

[0103] In some embodiments, the plurality of second lens groups 310 includes a first sub-lens group, a second sub-lens group and a third sub-lens group; the second sub-lens group is arranged at one side of the first sub-lens group along the first direction X, and the number of second lenses 310 in the second sub-lens group is greater than that in the first sub-lens group; the third sub-lens group is arranged at the other side of the first sub-lens group along the first direction X away from the second sub-lens group, and the number of second lenses 310 in the third sub-lens group is greater than that in the first sub-lens group. Please refer to Figure 1 , Figure 5 and Figure 15 .

[0104] In other words, in some embodiments, the number of light sources 111 in the plurality of light source groups 110 decreases first and then increases along the first direction X.

[0105] In the above embodiments, the number of light sources 111 in the light source groups 110 located at both sides of the first direction X is greater than that in the light source groups 110 located in the middle, which can allow the power of the light sources 111 in the light source groups 110 located at both ends of the first direction X to decrease along the edges of the first direction X, so that the light pattern formed by the lighting device produces a gradual change effect along the first direction X at the edges, making the light pattern formed by the lighting device more beautiful and the lighting effect of the lighting device better.

[0106] In some embodiments, the light source group 110 includes a plurality of second light source groups 110 arranged along the first direction X; in adjacent two second light source groups 110, the number of light sources 111 included in the one away from the first light source group 110 is greater than or equal to that in the other; the light source group 110 includes a plurality of third light source groups 110 arranged along the first direction X; in adjacent two third light source groups 110, the number of light sources 111 included in the one away from the first light source group 110 is greater than or equal to that in the other.

[0107] In some embodiments, the number of light sources 111 in the plurality of second light source groups 110 decreases towards the first light source group 110 along the first direction X, and the number of light sources 111 in adjacent second light source groups 110 can be equal; in some embodiments, the number of light sources 111 in the plurality of third light source groups 110 decreases towards the first light source group 110 along the first direction X, and the number of light sources 111 in adjacent third light source groups 110 can be equal.

[0108] In some embodiments, the number of second lenses 310 in the plurality of second sub-lens groups decreases along the first direction X towards the first sub-lens group, and the number of second lenses 310 in adjacent second sub-lens groups can be equal; in some embodiments, the number of second lenses 310 in the plurality of third sub-lens groups decreases along the first direction X towards the first sub-lens group, and the number of second lenses 310 in adjacent third sub-lens groups can be equal, please refer to Figure 1 , Figure 5 and Figure 15 .

[0109] It can be understood that the light pattern generated by the lighting device needs to be bright in the middle and dark on both sides, that is, the light sources 111 located in the middle need to be operated at a higher power, and the light sources 111 closer to both sides can be operated at a lower power.

[0110] In the above embodiments, the number of light sources 111 in the light source group 110 closer to the middle is less to avoid generating more heat when operated at a high power; and the number of light sources 111 in the light source group 110 closer to both sides is more, which is not easy to generate more heat when operated at a low power, and because the number is more, a gradual change effect can be generated, so that the lighting device including the light source group 110 has a better and more beautiful light pattern.
