[0036] The core of this application is to provide a lighting module to simplify the structure of the lighting module.
[0037] Another core of the present application is to provide a vehicle having the above-mentioned lighting module.
[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0039] Traditional lighting modules typically include an inner lens and an outer lens, which are supported and fixed by structural members, such as upper and lower supports or front and back supports. This results in a large number of parts in the entire lighting module, a complex assembly process, and high costs. Furthermore, errors are easily introduced during the assembly process, affecting optical accuracy.
[0040] For this reason, Figure 1 and Figure 2 As shown, the embodiment of the present application discloses a lighting module, including a heat sink 100, a light source assembly 200, and an optical lens 300. By designing a special optical lens 300 and directly assembling the optical lens 300 on the light source assembly 200 without adding a supporting structure, the problem of traditional lighting modules having a large number of parts and a complex assembly process, which leads to assembly errors, is solved. At the same time, the lighting module only requires three parts, namely the light source assembly 200, the heat sink 100, and the optical lens 300, thereby simplifying the structure of the lighting module and reducing design and product costs.
[0041] The following will be combined Figures 1 to 6 The lighting module disclosed in the embodiments of the present application is specifically explained and illustrated.
[0042] Among them, Figure 1 and Figure 2 As shown, the light source assembly 200 is directly mounted on the heat sink 100, and the optical lens 300 is assembled on the light source assembly 200 without adding a supporting structure, which solves the problem of large number of parts and complicated assembly process of traditional lighting modules, which leads to assembly errors. At the same time, the lighting module only needs three parts, namely the light source assembly 200, the heat sink 100 and the optical lens 300, thereby simplifying the structure of the lighting module and reducing design and product costs.
[0043] In order to realize the lighting pattern of the car, Figure 3 As shown, the optical lens 300 has a light incident surface 301 and a light emitting surface 302 that are relatively arranged, and the optical lens 300 includes at least two reflective surfaces inclined toward the light emitting surface 302 of the optical lens 300, so that the shape of the light pattern can be adjusted through multiple reflective surfaces, so that when the light emitted by the light source assembly 200 passes through the light incident surface 301, it is reflected by each reflective surface to the light emitting surface 302, thereby forming a light pattern that meets automobile lighting regulations.
[0044] In some embodiments, the optical lens 300 may have a Z-shaped structure, and the reflective surfaces may be two parallel surfaces. For ease of understanding, the two reflective surfaces are defined as a first reflective surface 303 and a second reflective surface 304, with the first reflective surface 303 located below the second reflective surface 304. When light emitted by the light source assembly 200 passes through the light incident surface 301, it can be directly incident on the first reflective surface 303. The first reflective surface 303 then totally reflects the light incident thereon to the second reflective surface 304. The second reflective surface 304 then reflects the light reflected thereon to the light exiting surface 302, thereby forming a light pattern that meets automotive lighting regulations.
[0045] Of course, if Figure 3 As shown, the optical lens 300 may also be provided with three reflective surfaces, that is, a third reflective surface 305 is added on the basis of the above embodiment, and the third reflective surface 305 is on the same side as the second reflective surface 304 and connected to the second reflective surface 304. When the light emitted by the light source assembly 200 passes through the light incident surface 301, part of the light may be directly incident on the first reflective surface 303, and then the first reflective surface 303 will totally reflect the light incident thereon to the second reflective surface 304, and then the light reflected thereon will be reflected to the light emitting surface 302 by the second reflective surface 304. At the same time, part of the light may be directly incident on the third reflective surface 305, and then the third reflective surface 305 will totally reflect the light incident thereon to the first reflective surface 303, and then the first reflective surface 303 will totally reflect the light reflected thereon to the second reflective surface 304, and then the second reflective surface 304 will reflect the light reflected thereon to the light emitting surface 302, thereby forming a light pattern that ultimately meets automotive lighting regulations. It should be noted that in order for the light emitted by the light source assembly 200 to be reflected three times and emitted from the light-emitting surface 302 of the optical lens 300, there must be a preset angle γ between the third reflecting surface 305 and the second reflecting surface 304, and 90°<γ<180°. For example, the preset angle γ can be 120°, 145°, etc.
[0046] It should be noted that the optical lens 300 may also adopt a stepped structure, so that the reflective surfaces are not limited to two or three as in the above embodiment, but may be four, five or more, thereby forming a light pattern that meets automobile lighting regulations.
[0047] In order to improve the focusing effect of the lighting module, in some embodiments, such as Figure 3 and Figure 4 As shown, the third reflective surface 305 can be in a parabolic shape, and the number of the third reflective surfaces 305 is at least two, and each third reflective surface 305 is distributed along the horizontal direction of the lighting module, thereby improving the light focusing efficiency, achieving high-power light focusing, and enhancing the stability and reliability of the lighting module. Figure 4 As shown, there may be two, three, four or more third reflective surfaces 305, which is not limited herein.
[0048] In order to increase the reflectivity of the reflective surface and improve the lighting effect of the lighting module, in some embodiments, such as Figure 5 and Figure 6 As shown, an aluminum reflective layer 306 can be covered on each reflective surface to improve the reflectivity of the reflective surface by coating a metal aluminum film on the reflective surface. At the same time, a light-shielding layer 307 can be covered on the non-reflective surface to prevent light leakage by spraying an anti-reflective coating or a light-shielding paint, thereby meeting the appearance requirements of the lighting module. In addition, a connecting plate 309 is provided at the incident end of the optical lens 300, and the connecting plate 309 has a first side and a second side that are relatively arranged, and a baffle 310 is provided on the first side and the second side of the connecting plate 309 to form a light-shielding groove 3101 by the baffle 310 and the connecting plate 309. The third reflective surface 305 is located in the light-shielding groove 3101 to avoid light leakage, thereby improving the focusing effect. The light incident surface 301 of the optical lens 300 is located on the side of the connecting plate 309 close to the light source assembly 200. It should be noted that in the above embodiment, the non-reflective surface refers to other areas except the reflective surface, such as the side wall of the optical lens 300, the straight section close to the light emitting surface 302 of the optical lens 300, and the baffle 310 and other position areas.
[0049] In order to facilitate the assembly of the lighting module, in some embodiments, such as Figure 1 As shown, a mounting surface 101 is provided on the heat sink 100. The mounting surface 101 is designed to be flat so as to install the light source assembly 200. At the same time, the mounting surface 101 is tilted toward the reflecting surface so that the light emitted by the light source assembly 200 on the mounting surface 101 passes through the light incident surface 301 of the optical lens 300 and is directly projected onto the reflecting surface.
[0050] In some embodiments, as Figure 1As shown, the light source assembly 200 includes a PCB board 201 and an LED light source 202 disposed on the PCB board 201. The LED light sources 202 can be two or more to match the reflective surface. A controller 2021 for controlling the LED light sources 202 is also provided on the PCB board 201. During assembly, the optical lens 300, the PCB board 201, and the mounting surface 101 of the radiator 100 can be connected via fasteners 400, such as bolts. Specifically, at least two limiting posts 1011 are provided on the mounting surface 101 of the radiator 100, and a limiting groove 2011 is provided on the PCB board 201 to match the limiting posts 1011. When the light source assembly 200 is installed, the limiting posts 1011 on the mounting surface 101 of the radiator 100 can be snapped into the limiting groove 2011 on the PCB board 201 to achieve positioning of the light source assembly 200. At the same time, a first mounting hole 1012 is provided on the mounting surface 101 of the radiator 100, and a second mounting hole 308 is provided on the connecting plate 309 of the optical lens 300, so that the connecting plate 309 of the optical lens 300 can pass through the second mounting hole 308 and the first mounting hole 1012 in sequence through fasteners 400 such as bolts, thereby fixing the optical lens 300 to the mounting surface 101 of the radiator 100. At this time, the light source assembly 200 can be pressed between the connecting plate 309 of the optical lens 300 and the mounting surface 101 of the radiator 100, thereby realizing rapid assembly of the lighting module, such as Figure 2 As shown. It should be noted that three first mounting holes 1012 can be used, and they are located at three different side positions on the mounting surface 101 of the heat sink 100. At the same time, the second mounting holes 308 on the connecting plate 309 of the optical lens 300 are adapted to the first mounting holes 1012, so that a three-point fixation method can be formed through three fasteners 400, ensuring the reliability and stability of the lighting module assembly. Of course, two, four, or more first mounting holes 1012 can also be used, and the second mounting holes 308 are adapted to the first mounting holes 1012 to achieve the assembly of the lighting module.
[0051] In the above embodiment, if Figure 1 As shown, the PCB board 201 is provided with an escape opening 2012 to avoid the fastener 400 and prevent the PCB board 201 from affecting the installation of the fastener 400. Figure 5 and Figure 6As shown, a notch 3091 is provided on the connecting plate 309 of the optical lens 300. This allows the controller 2021 on the PCB 201 to be positioned within the notch 3091 when the optical lens 300 is secured to the mounting surface 101 of the heat sink 100, thereby preventing the controller 2021 on the PCB 201 from interfering with the installation of the optical lens 300. Furthermore, a protective housing 3092 can be provided at the location of the notch 3091 of the connecting plate 309 to effectively protect the controller 2021, preventing dust and water from entering the controller 221 and thereby extending the service life of the lighting module.
