[0054] The core of this application is to provide a lighting module that can reduce costs while meeting the low beam optical performance requirements.

[0055] Another core of the present application is to provide a vehicle having the above-mentioned lighting module.

[0056] 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.

[0057] For this reason, Figure 1 As shown, the embodiment of the present application discloses a lighting module, including a light-shaped baffle 100, a reflector 200, and a light source assembly 300. By providing multiple reflectors 200 and each reflector 200 sharing a light source assembly 300, a low beam module can be formed to provide supplementary light for the high beam while also providing supplementary light for the low beam, thereby maximizing light efficiency and reducing costs while meeting the optical performance requirements of the low beam.

[0058] The following will be combined Figures 1 to 15 The lighting module disclosed in the embodiments of the present application is specifically explained and illustrated.

[0059] Among them, such as Figure 1 and Figure 5As shown, there are at least two reflectors 200, and the reflectors 200 include a first reflector 201 and a second reflector 202. The first reflector 201 is located on the upper side of the light baffle 100 to form a low beam below the light baffle 100, and the second reflector 202 is located on the lower side of the light baffle 100 to form a high beam above the light baffle 100. At the same time, the light source assembly 300 is disposed on the lower side of the light baffle 100 so that the light emitted by the light source assembly 300 can be reflected by the first reflector 201 and / or the second reflector 202. Figures 6 to 8 As shown, when the high beam is turned on, the light emitted by the light source assembly 300 can be reflected by the second reflector 202 to form a high beam light above the light-type baffle 100; when the low beam is turned on, the light emitted by the light source assembly 300 can be reflected by the first reflector 201 to form a low beam light below the light-type baffle 100, and at the same time, part of the light can be reflected by the second reflector 202 to supplement the low beam zone III 402, thereby increasing the irradiation distance and width of the low beam, and then maximizing the use of light efficiency, while meeting the low beam optical performance requirements and reducing costs.

[0060] Of course, the number of reflectors 200 is not limited to two in the above embodiment, that is, the first reflector 201 and the second reflector 202 are one each. The number of reflectors 200 can also be three, four or more, that is, the number of first reflectors 201 can be one, two, three or more, and the number of second reflectors 202 can be one, two, three or more, which is not limited in this article.

[0061] In the above embodiment, if Figure 6 As shown, a predetermined angle θ is formed between the light output axis 3021 of the light source assembly 300 and the light pattern baffle 100, and 0°<θ<180°. Preferably, the predetermined angle θ between the light output axis 3021 of the light source assembly 300 and the light pattern baffle 100 can be 90°, that is, the light output axis 3021 of the light source assembly 300 is arranged perpendicular to the light pattern baffle 100.

[0062] In some embodiments, as Figure 10As shown, the light source assembly 300 may include a PCB board 301 and an LED light source 302 disposed on the PCB board 301. The LED light source 302 may utilize multi-chip LED particles, wherein the LED light source 302 may include multiple LED chips, and the lighting of corresponding LED particles may be controlled by the LED chips. The LED chips include a first LED chip and a second LED chip. The first LED chip can illuminate the corresponding LED particles to form high-beam illumination, and the second LED chip can illuminate the corresponding LED particles to form low-beam illumination. Specifically, the first LED chip includes a high-beam particle chip and a fill-light particle chip. When the high beam is turned on, the high beam particle chip lights up the LED particles corresponding to the high beam, and the high beam light is reflected by the second reflector 202 to form high beam illumination, and the fill light particle chip turns off the LED particles corresponding to the fill light, and at the same time, the second LED chip turns off the LED particles corresponding to the low beam; when the low beam is turned on, the second LED chip lights up the LED particles corresponding to the low beam, and the low beam light is reflected by the first reflector 201 to form low beam illumination, and the high beam particle chip turns off the LED particles corresponding to the high beam, and the fill light particle chip lights up the LED particles corresponding to the fill light, and at the same time, the fill light light is reflected by the second reflector 202 to fill in the low beam zone III 402.

[0063] As can be seen from the above embodiment, by using multi-chip LED particles in the LED light source 302, high beam and low beam can be independently controlled to meet regulations for low beam and high beam, respectively. Furthermore, by using a single LED light source 302 shared by the first reflector 201 and the second reflector 202, high beam can be simultaneously activated and supplemented with low beam, thereby increasing the illumination range and width of the low beam and maximizing light efficiency, while meeting low beam optical performance requirements and reducing costs. Furthermore, the light pattern baffle 100 can separate the low beam and low beam supplementary beam, allowing independent control of the low beam and low beam supplementary beam. This allows for adjustment of lighting intensity and range according to different driving environments and needs, resulting in more efficient use of the light source, improved lighting efficiency, and ensuring appropriate lighting in various road conditions. The low beam can illuminate the road ahead of the vehicle, while the low beam supplementary beam provides supplementary illumination. The segmented light pattern baffle 100 allows for precise control of light distribution, avoiding glare to oncoming drivers or pedestrians, thereby improving driving safety.

[0064] In some embodiments, the light baffle 100 can be made of two metal materials of different thicknesses, such as SUS304. Specifically, the light baffle 100 can include a first metal plate and a second metal plate stacked with the first metal plate, and the thickness of the first metal plate is greater than that of the second metal plate to improve the strength of the light baffle 100. At the same time, the second metal plate and the first metal plate can be connected at multiple connection points 103 by riveting or laser welding, such as Figure 12 and Figure 13 In addition, Figure 7 and Figure 12 As shown, the light baffle 100 can be bent so that the cutoff line 101 of the light baffle 100 forms an inflection point 1011, thereby helping to optimize the distribution of light, reduce unnecessary scattering and reflection, and improve the driver's visual comfort. The distribution of light can also be precisely controlled to avoid glare to oncoming drivers or pedestrians, thereby improving driving safety. The design of the inflection point 1011 enables the headlight to adjust the lighting intensity and range according to different driving environments and needs, providing a safer lighting solution. Of course, as Figure 8 and Figure 13 As shown, the surface of the light-type baffle 100 can also be designed to be flat, so that all points on the cut-off line 101 are located in the same plane, and an HD module or an ADB module can be superimposed to realize the inflection point 1011 of the cut-off line 101, as shown in FIG. Figure 9 As shown, by superimposing an HD module or an ADB module, the brightness of the low beam part can be improved. For example, when the HD module is superimposed, the brightness of the HD lighting area 104 can be improved, and the inflection point 1011 of the low beam cut-off line 101 and the B50L regulatory characteristic requirements can be achieved.

[0065] like Figures 1 to 3 As shown, the lighting module further includes an outer lens 400 and a lens bracket 500. The outer lens 400 can be snap-fitted to the lens bracket 500.

[0066] In some embodiments, as Figures 1 to 3 As shown, the outer lens 400 can adopt an opening diameter of 70mm on the light-emitting surface, and the appearance surface of the outer lens 400 can be directly used as the styling surface of the entire vehicle. Figure 11 As shown, when the low beam is turned on, a textured area 401 can be added to the outer lens 400 to blur the cutoff line 101 of the light baffle 100 to avoid generating sharp light and meet the regulatory requirements of the low beam zone III 402.

[0067] In the above embodiment, since the lens holder 500 is a plastic part, in order to prevent the light from being refracted by the outer lens 400 and focused on the lens holder 500, the lens holder 500 is ablated. Figure 4 As shown, an ablation sheet 501 can be provided on the lens holder 500, wherein the ablation sheet 501 can be made of metal material, and the ablation sheet 501 and the lens holder 500 can be connected by snap-fitting, or connected by fasteners such as bolts. Of course, both snap-fitting and fasteners such as bolts can be used at the same time to ensure the reliability of the connection between the ablation sheet 501 and the lens holder 500.

[0068] like Figure 1 and Figure 2As shown, the lighting module further includes a heat sink 600, and the light source assembly 300 and the heat sink 600 can be connected by fasteners such as bolts. Figure 15 As shown, a thermal conductive adhesive 601 is filled between the light source assembly 300 and the heat sink 600 , so that the heat of the light source assembly 300 can be transferred to the heat sink 600 through the thermal conductive adhesive 601 to improve the heat dissipation efficiency.

[0069] To facilitate the assembly of the heat sink 600, in some embodiments, as Figure 15 As shown, the mounting surface of the heat sink 600 is flat, and the heat dissipation fins are all located on the underside of the mounting surface. This allows for better assembly of the light source assembly 300 with the mounting surface, while also increasing the contact area between the light source assembly 300 and the heat sink 600, thereby improving heat dissipation efficiency. Specifically, positioning posts 602 are provided on the mounting surface of the heat sink 600, so that the positioning posts 602 can cooperate with the positioning holes of the PCB board 301 of the light source assembly 300 to achieve the installation and positioning of the light source assembly 300. Furthermore, connection holes 603 are provided on the mounting surface of the heat sink 600. After the second reflector 202 is connected to the light baffle 100 by hot riveting at the hot riveting point 102 of the light baffle 100, the first positioning hole 2021 and the mounting hole 2022 of the second reflector 202 can be matched with the second positioning hole 603 and the connecting hole 604 on the mounting surface of the heat sink 600 respectively, and the second reflector 202, the first reflector 201 and the heat sink 600 can be fixed to the lens bracket 500 by fasteners such as bolts, thereby realizing the assembly of the lighting module. Figure 1 As shown in the above embodiment, by press-fitting and positioning the first reflector 201, the second reflector 202, and the heat sink 600, the transmission of the dimensional chain is reduced, ensuring precision while facilitating processing and manufacturing. At the same time, the press-fitting method of multiple reflectors 200 can simplify the structure of the heat sink 600, thereby achieving a high heat dissipation solution.

[0070] In the above embodiment, the heat sink 600 can be made of AL1070 high thermal conductivity material, and a high heat dissipation heat sink 600 can be formed by cold forging to meet the customer's higher heat dissipation requirements. At the same time, the fan can be omitted, reducing costs.
