[0024] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] The present application provides a lighting system 100 that can be used in a vehicle as a vehicle lamp (e.g., a headlight). Referring to FIG1 , the lighting system 100 may include a laser light source 120 and a lamp assembly 200. The laser light source 120 is configured to generate a designated laser light L. The lamp assembly 200 is connected to the laser light source 120 and is located in the optical path of the designated laser light L. Specifically, the designated laser light L is a blue laser.

[0026] In some possible embodiments, the laser light source 120 may be integrated into the interior of the vehicle lamp assembly 200 to make the overall structure of the lighting system 100 more compact.

[0027] In some other possible embodiments, as shown in FIG. 1 , the lighting system 100 may further include a housing 140 , and the vehicle light assembly 200 is disposed in the housing 140 . The housing 140 may serve to fix and protect the lighting system 100 .

[0028] The laser light source 120 may include a laser generator 1210, a laser connector 1230, and an optical fiber 1250. The laser generator 1210 is disposed outside the housing 140 and is used to generate a designated laser light L. Specifically, the laser generator 1210 may be a blue laser tube. The laser generator 1210 and the laser connector 1230 are respectively connected to the ends of the optical fiber 1250, and the laser connector 1230 is connected to the vehicle lamp assembly 200. In other words, the designated laser light L generated by the laser generator 1210 is coupled into the vehicle lamp assembly 200 via the optical fiber 1250 and then emitted to the vehicle lamp assembly 200 through the laser connector 1230. Specifically, the laser connector 1230 may be disposed within the housing 140, which further includes a mounting hole for the optical fiber 1250 to pass through. The end of the optical fiber 1250 away from the laser generator 1210 passes through the mounting hole and is then connected to the laser connector 1230.

[0029] In some possible embodiments, one or more collimating lenses (not shown in the figure) can be provided at the light outlet of the laser connector 1230. The collimating lens is used to collimate the specified laser L and then emit it to the headlight assembly 200 to improve the energy utilization efficiency of the specified laser L.

[0030] Therefore, by placing the laser generator 1210 outside the housing 140, this embodiment can, on the one hand, reduce the overall volume of the vehicle lamp assembly 200, achieving a compact design. On the other hand, the high temperatures generated by the laser generator 1210 during operation can be isolated outside the housing 140, reducing the temperature inside the housing 140 and ensuring the operating efficiency of the lighting system 100. Furthermore, the laser generator 1210 can be flexibly installed in a designated location in the vehicle via the optical fiber 1250, improving the heat dissipation efficiency of the laser generator 1210.

[0031] In this embodiment, the vehicle lamp assembly 200 is arranged on the optical path where the designated laser L is located, and is used to generate a designated fluorescence F under the excitation of the designated laser L, and emit the designated fluorescence F to the outside world. Referring to Figure 2, the vehicle lamp assembly 200 may include a base 210, a light-transmitting member 230, a light-guiding member 250, and a fluorescent member 270. Among them, the base 210 is used to connect to the laser light source 120, and the light-transmitting member 230 is connected to the base 210. The light-guiding member 250 is arranged on one side of the light-transmitting member 230 and is connected to the light-transmitting member 230. The light-guiding member 250 is located on the optical path where the designated laser L is located, and is used to guide the designated laser L to a designated area. The "designated area" here refers to the area where the fluorescent member 270 is located. The fluorescent member 270 is arranged on the side of the base 210 facing the transparent member 230 and is located on the optical path of the designated laser L emitted through the light guide 250. The fluorescent member 270 is used to generate designated fluorescence F under the excitation of the designated laser L, and the designated fluorescence F is emitted to the outside through the transparent member 230.

[0032] Because the vehicle lamp assembly 200 of this embodiment uses a laser as its illumination source, compared to LED light sources, laser light has a smaller spread and greater brightness. This allows the volume of the optical system within vehicle lamp assembly 200 to be reduced while ensuring sufficient luminous flux. Furthermore, the light guide 250 within vehicle lamp assembly 200 folds the laser light path, making the optical path within vehicle lamp assembly 200 more compact and facilitating a miniaturized design for vehicle lamp assembly 200.

[0033] The specific structure of the vehicle lamp assembly 200 is introduced below.

[0034] In this embodiment, the base 210 serves to securely support other structures (e.g., the light-transmitting member 230, the fluorescent member 270, etc.) in the vehicle lamp assembly 200. Specifically, the base 210 can be made of a metal material (e.g., a copper-aluminum composite material or an aluminum alloy), which can effectively dissipate heat from the fluorescent member 270 disposed on the base 210.

[0035] In some possible embodiments, the laser light source 120 may include a laser connector 1230 for emitting a designated laser light L. The base 210 may be provided with a mounting slot 2120 extending through opposite sides of the base 210. The laser connector 2120 is located on a side of the base 210 facing away from the light-transmitting member 230 and is embedded in the mounting slot 2120. The designated laser light L is incident upon the light-transmitting member 230 via the mounting slot 2120. Specifically, the laser connector 1230 and the mounting slot 2120 may be detachably connected via a threaded structure or a mortise and tenon structure. This allows the laser light source 120 to be separated from the vehicle lamp assembly 200 by disassembling the laser connector 1230 in the event of a malfunction, thereby facilitating repair and replacement of the laser light source 120.

[0036] Of course, in some other possible embodiments, the laser light source 120 may also be fixedly connected to the base 210, with the light outlet of the laser light source 120 disposed toward the light-transmitting member 230. This embodiment does not limit the specific arrangement of the laser light source 120.

[0037] In this embodiment, light-transmitting member 230 is connected to base 210 and is used to transmit the designated fluorescent light F generated by fluorescent member 270 to the outside world. Referring to FIG3 , light-transmitting member 230 may be a lens, comprising a light-collecting portion 2320 and a light-homogenizing portion 2340 . Light-collecting portion 2320 is located on the side of light-homogenizing portion 2340 facing base 210 , and is used to converge the designated fluorescent light F.

[0038] In some possible embodiments, the light collecting portion 2320 may be provided with a receiving groove 2321, which is located on the side of the light collecting portion 2320 facing the base 210. The light guide 250 and the fluorescent member 270 are disposed within the receiving groove 2321 so that the designated fluorescent light F emitted by the fluorescent member 270 enters the receiving groove 2321. Specifically, the bottom wall 2323 of the receiving groove 2321 is a curved surface convex toward the base 210, and the bottom wall 2323 can be used to converge the designated fluorescent light F. It is not difficult to see here that the area where the bottom wall 2323 is located can be regarded as a convex lens, thereby achieving the effect of converging the fluorescent light, thereby improving the energy utilization efficiency of the designated fluorescent light F.

[0039] In addition, arranging the light guide member 250 and the fluorescent member 270 in the receiving groove 2321 can also make the overall structure of the vehicle lamp assembly 200 more compact, thereby saving the installation space of the vehicle lamp assembly 200.

[0040] In some possible embodiments, the outer peripheral surface 2325 of the light collecting portion 2320 is a reflective surface, configured to reflect the designated fluorescent light F incident on the light collecting portion 2320 toward the light homogenizing portion 2340. The "designated fluorescent light F incident on the light collecting portion 2320" herein refers to the designated fluorescent light F incident on the outer peripheral surface 2325 via the peripheral wall 2327 of the receiving groove 2321. Because the designated fluorescent light F is spherical light, a portion of the designated fluorescent light F is converged by the bottom wall 2323 of the receiving groove 2321 and incident on the light homogenizing portion 2340, while a portion of the designated fluorescent light F enters the light collecting portion 2320 via the peripheral wall 2327 of the receiving groove 2321 and is reflected by the outer peripheral surface 2325 of the light collecting portion 2320 and incident on the light homogenizing portion 2340, thereby improving the energy utilization efficiency of the designated fluorescent light F. Specifically, the outer circumferential surface 2325 of the light collecting portion 2320 is generally conical, and the conical surface continuously converges toward the notch of the receiving groove 2321. The light-transmitting member 230 may be a total reflection lens, and the outer circumferential surface 2325 of the light collecting portion 2320 may be a total reflection surface, which may be coated with a total reflection film or plated with a total reflection metal layer to improve the reflection efficiency of the designated fluorescent light F.

[0041] In this embodiment, the light homogenizing portion 2340 is arranged toward the outside, and is used to homogenize the specified fluorescence F after being converged by the light collecting portion 2320. It should be noted here that the names of "light homogenizing portion" and "light collecting portion" are named for the convenience of description. In specific examples, there may be a clear dividing line between the two structures or there may not be a clear dividing line. For example, the two are assembled together or the two are an integrally formed structure. In some possible embodiments, the light collecting portion 2320 and the light homogenizing portion 2340 may be an integrally formed structure, that is, the light collecting portion 2320 and the light homogenizing portion 2340 are different parts of the same component, one part of which is used to converge the fluorescence, and the other part is used to homogenize the fluorescence. Specifically, the light-transmitting member 230 can be made of a material with good light transmittance, such as glass or plastic optical material, and it can be regarded as an irregularly shaped lens.

[0042] In some possible embodiments, the light uniforming portion 2340 may include a light emitting surface 2341 facing away from the light collecting portion 2320, and a plurality of light uniforming structures 2343 are provided on the light emitting surface 2341, and the plurality of light uniforming structures 2343 are arranged in an array to uniformly light the specified fluorescent light F, so that the illumination brightness of the specified fluorescent light F is more uniform, thereby improving the lighting effect of the vehicle lamp assembly 200. Specifically, the light uniforming structure 2343 can protrude toward one side of the outside world to be equivalent to a single convex lens. In other words, the plurality of light uniforming structures 2343 can be regarded as a lens array to ensure the light uniforming effect. The plurality of light uniforming structures 2343 can be arranged in an M*N rectangular array, or in an annular array (for example, in the shape of concentric rings). This embodiment does not limit the specific implementation method of the light uniforming structure 2343.

[0043] In some possible embodiments, the outer circumferential surface 2345 of the light homogenizing portion 2340 is continuous with the outer circumferential surface 2325 of the light collecting portion 2320, and the outer circumferential surface 2345 of the light homogenizing portion 2340 is a reflective surface. In some possible scenarios, a portion of the designated fluorescent light F will propagate through the peripheral wall 2327 of the receiving groove 2321, sequentially passing through the light collecting portion 2320 and the light homogenizing portion 2340, before being incident on the outer circumferential surface 2345 of the light homogenizing portion 2340. Reflected by the outer circumferential surface 2345 of the light homogenizing portion 2340, the light is then emitted through the light emitting surface 2341, thereby improving the energy utilization efficiency of the designated fluorescent light F. Specifically, the outer circumferential surface 2345 of the light homogenizing portion 2340 may be coated with a total reflection film or a total reflection metal layer to improve the reflection efficiency of the designated fluorescent light F.

[0044] It should be noted here that since the headlight assembly 200 in this embodiment uses laser as the light source, while ensuring the luminous flux, the spot size of the specified fluorescent light F emitted through the light-emitting surface 2341 (that is, the optical window size) can be less than or equal to 15mm*15mm, so as to facilitate the miniaturization design of the headlight assembly 200.

[0045] In this embodiment, the light guide 250 is used to guide the propagation direction of the designated laser light L so that the designated laser light L is transmitted to the location of the fluorescent member 270. In the embodiment shown in FIG2 , the light guide 250 can be disposed within the receiving groove 2321 and located on the side of the bottom wall 2323 facing the base 210.

[0046] Referring to FIG. 4 , the light guide 250 may be a prism 2520. The prism 2520 may be integrally formed from a material with good light transmittance, such as glass or plastic optical material. The prism 2520 may be attached to the side of the bottom wall 2323 facing the base 210 by adhesive, or embedded in the bottom wall 2323, to provide a more stable connection between the prism 2520 and the light-transmitting member 230. Specifically, the prism 2520 may include a first reflective surface 2521 and a second reflective surface 2523, which are sequentially arranged in the optical path of the designated laser light L and are configured to reflect the designated laser light L toward the fluorescent member 270. In some possible embodiments, the first reflective surface 2521 and the second reflective surface 2523 may each be coated with a total reflection film or plated with a total reflection metal layer to achieve total reflection of the designated laser light L, thereby improving the energy utilization efficiency of the designated laser light L.

[0047] Of course, in some other possible embodiments, the light guide 250 may also be implemented by using a plurality of reflectors, which are disposed in the receiving groove 2321 to reflect the designated laser L to the fluorescent member 270 .

[0048] In some possible embodiments, the light outlet of the laser light source 120 and the fluorescent element 270 are located on the same side of the prism 2520. The "light outlet of the laser light source 120" herein may be the opening formed by the mounting slot 2120 extending through the side of the base 210 toward the light-transmitting element 230 in Figure 2 . The designated laser light L generated by the laser light source 120 is incident on the prism 2520 located within the receiving slot 2321 through this light outlet. Because the light outlet of the laser light source 120 and the fluorescent element 270 are located on the same side, the designated laser light L is reflected twice by the prism 2520 and then emitted back toward the base 210. Therefore, the prism 2520 in this embodiment directs the designated laser light L to the fluorescent element 270 using a TIR double-reflection normal incidence method. This not only ensures maximum fluorescence excitation efficiency but also folds the laser light path, making the optical path within the vehicle lamp assembly 200 more compact and facilitating a compact design for the vehicle lamp assembly 200. In addition, the designated laser L is incident almost vertically on the fluorescent element 270 to ensure that the spot size incident on the fluorescent element 270 is minimized, thereby reducing the size and area of ​​the fluorescent element 270 and lowering the manufacturing cost of the fluorescent element 270 .

[0049] In some possible embodiments, the bottom wall 2323 of the receiving groove 2321 is provided with a scattering region 2329, which is positioned opposite the light outlet of the laser light source 120. Specifically, the scattering region 2329 is provided with multiple microstructures, which are configured to scatter light incident on the scattering region 2329. For example, the multiple microstructures may be uneven, raised structures or multiple scattering particles. When the prism 2520 detaches from the bottom wall 2323, the designated laser light L will be directly incident on the scattering region 2329. The presence of the multiple microstructures can scatter the designated laser light L, thereby preventing the designated laser light L from being directly emitted from the light-transmitting member 230 and entering the eyes of pedestrians or other drivers outside the vehicle. Furthermore, when the prism 2520 is attached to the bottom wall 2323, because the first reflective surface 2521 cannot fully reflect the designated laser light L, some of the designated laser light L may leak from the first reflective surface 2521 and be transmitted to the scattering region 2329. Therefore, the multiple microstructures can also be used to scatter the leaked laser light to prevent it from directly emitting from the light-transmitting element 230 and damaging the eyes of pedestrians or drivers of other vehicles.

[0050] In this embodiment, the fluorescent member 270 is disposed on the side of the base 210 facing the light-transmitting member 230 and is located in the optical path of the designated laser light L emitted by the light guide 250. The fluorescent member 270 is configured to generate a designated fluorescent light F under the excitation of the designated laser light L. Specifically, the designated fluorescent light F may be white fluorescent light, and the fluorescent member 270 may be a fluorescent powder sheet that may be embedded in or attached to the base 210. Alternatively, the fluorescent member 270 may be a colloid doped with fluorescent particles that may be coated on the surface of the base 210. This embodiment does not limit the specific implementation of the fluorescent member 270.

[0051] The present application provides a vehicle lamp assembly 200 and a lighting system 100 equipped with the vehicle lamp assembly 200. The vehicle lamp assembly 200 may include a base 210, a light-transmitting member 230, a light-guiding member 250, and a fluorescent member 270. The base 210 is used to connect to the laser light source 120, and the light-transmitting member 230 is connected to the base 210. The light-guiding member 250 is disposed on one side of the light-transmitting member 230 and is connected to the light-transmitting member 230. The light-guiding member 250 is located on the optical path of the designated laser L and is used to guide the designated laser L to a designated area. The "designated area" here refers to the area where the fluorescent member 270 is located. The fluorescent member 270 is disposed on the side of the base 210 facing the light-transmitting member 230 and is located on the optical path of the designated laser L emitted through the light-guiding member 250. The fluorescent member 270 is used to generate a designated fluorescent light F under the excitation of the designated laser L, and the designated fluorescent light F is emitted to the outside through the light-transmitting member 230.

[0052] Because the vehicle lamp assembly 200 of this embodiment uses a laser as its illumination source, compared to LED light sources, laser light has a smaller spread and greater brightness. This allows the volume of the optical system within vehicle lamp assembly 200 to be reduced while ensuring sufficient luminous flux. Furthermore, the light guide 250 within vehicle lamp assembly 200 folds the laser light path, making the optical path within vehicle lamp assembly 200 more compact and facilitating a miniaturized design for vehicle lamp assembly 200.
