[0041] The core of this application is to provide a headlight to prevent the low beam zone III from being too bright.
[0042] Another core of the present application is to provide a vehicle having the above-mentioned headlight.
[0043] 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.
[0044] As modern cars continue to pursue higher performance and appearance of headlights, it is necessary to ensure the appearance while meeting the high and low beam performance and regulatory requirements. The low beam regulations require that the headlights must avoid excessive brightness in the low beam zone III to prevent the excessive brightness in the low beam zone III from affecting driving safety.
[0045] For this reason, Figure 1 As shown, the embodiment of the present application discloses a headlight, comprising an outer cover 100 and a lighting module 200. By movably arranging the lighting module 200 on the inner side of the outer cover 100, the lighting module 200 can be adjusted in elevation and depression, thereby preventing glare to drivers of oncoming vehicles, increasing the illumination distance, and improving the lighting effect. At the same time, the slider line 101 of the outer cover 100 is located outside the dimming envelope 201, and the light output envelope radius 102 of the outer cover 100 is not less than 120 mm, so as to avoid the formation of stray light 500 in the low beam III zone 400 of the headlight, making the low beam III zone 400 of the headlight appear super bright, thereby causing glare to drivers of oncoming vehicles.
[0046] The following will be combined Figures 1 to 10The vehicle lamp disclosed in the embodiment of the present application is specifically explained and illustrated.
[0047] Among them, Figure 1 and Figure 2 As shown, the outer cover 100 generally has multiple curved surfaces, and in order to facilitate the processing and manufacturing of the outer cover 100, it can be prepared by splicing blocks together, so that a slider line 101 is formed at the location of the block splicing, and the outer cover 100 is provided with a light envelope fillet 102. The lighting module 200 is movably arranged on the inner side of the outer cover 100 so that the lighting module 200 can be adjusted in elevation and depression, thereby forming a dimming envelope area 201. Figure 1 As shown, when the vehicle is on an uphill slope, the lighting module 200 can be adjusted to a pitch angle α2 to prevent dazzling the driver of the oncoming vehicle; when the vehicle is on a downhill slope, the lighting module 200 can be adjusted to an elevation angle α1 to increase the illumination distance and enhance the lighting effect. In addition, the light emitting envelope fillet 102 of the outer cover 100 cannot be too small to prevent the light emitted by the lighting module 200 from converging at the light emitting envelope fillet 102 of the outer cover 100, forming stray light 500, making the low beam III zone 400 of the vehicle headlights too bright, causing dazzling to the driver of the oncoming vehicle, as shown in FIG. Figure 3 and Figure 5 At the same time, the slider line 101 of the outer cover 100 should be located outside the dimming envelope 201 to prevent the light emitted by the lighting module 200 from being refracted and / or reflected at the slider line 101 of the outer cover 100 to form stray light, making the low beam III zone 400 of the vehicle lamp too bright.
[0048] In some embodiments, the lighting module 200 can be dimmed upward by 2°, i.e., the elevation angle α1 is 2°, and dimmed downward by 4°, i.e., the depression angle α2 is 4°. Furthermore, the slider line 101 of the outer cover 100 should be avoided within the dimming envelope 201. In other words, the slider line 101 of the outer cover 100 should be located outside the dimming envelope 201 to prevent light emitted by the lighting module 200 from being refracted and / or reflected at the slider line 101 of the outer cover 100, thereby forming stray light. Furthermore, the light output envelope radius 102 may be no less than 120 mm to ensure uniform light output from the outer cover 100 and to prevent light emitted by the lighting module 200 from being concentrated at the light output envelope radius 102 of the outer cover 100, thereby forming stray light 500 and causing excessive brightness in the low beam zone III 400 of the vehicle headlights, thereby dazzling oncoming drivers.
[0049] In order to meet the requirements of vehicle lamp styling and signal lamp function, in some embodiments, such as Figure 4 As shown, the headlight further includes an inner cover 300, and the inner cover 300 is located between the outer cover 100 and the lighting module 200, so as to blur the lighting module 200 and prevent the lighting module 200 from being exposed. Figure 6As shown, to meet the styling requirements of the headlight, a textured area 301 can be provided on the inner mask 300. The textured area 301 can be provided on the outer side of the inner mask 300, i.e., the side close to the outer mask 100, or on the inner side of the inner mask 300, i.e., the side close to the lighting module 200. The textured area 301 can be a floral pattern or a leather pattern, and the specific selection can be based on actual conditions.
[0050] like Figure 5 and Figure 6 As shown, the light emitted by the lighting module 200 is emitted through the inner mask 300 to form an envelope area 302 and a non-envelope area 303 on the inner mask 300 for the light emission of the lighting module 200. Since the texture area 301 is provided on the inner or outer side of the inner mask 300, the light emitted by the lighting module 200 is easily refracted and / or reflected at the position of the texture area 301, thereby forming stray light 500, making the low beam III area 400 of the vehicle headlights super bright. Therefore, the low beam regulations require that the illuminance value of the stray light 500 of the low beam III area 400 shall not exceed 1x. To this end, the texture area 301 can be located outside the envelope area 302, that is, the texture area 301 can be moved upward so that it is removed from the range of the envelope area 302. Or the depth of the texture area 301 of the envelope area 302 can be reduced so that the depth of the texture area 301 of the envelope area 302 is less than the depth of the texture area 301 of the non-envelope area 303. By Figure 7 It can be seen that when the texture area 301 adopts leather grain, the deeper the leather grain model, the more likely it is to cause the low beam III zone 400 to be too bright and fail to meet the low beam regulatory requirements, and Emax (maximum illuminance value) is reduced, resulting in reduced optical performance, such as the leather grain of VDI24 model and the leather grain of VDI15 model. In this embodiment, the leather grain VDI12 with a shallower leather grain depth can be selected.
[0051] In some embodiments, as Figure 8 and Figure 9 As shown, the lighting module 200 may include an outer lens assembly 202, an inner lens 203, a light pattern baffle 204, and a light source assembly 205. The outer lens assembly 202 may include an outer lens 2021 and lens holders 2022 located on either side of the outer lens 2021. For ease of understanding, the two lens holders 2022 are defined as a first holder and a second holder, respectively. The first holder is located above the outer lens 2021, and the second holder is located below the outer lens 2021. When the first holder and the second holder are connected via fasteners such as bolts, the outer lens 2021 can be snapped onto the ends of the lens holders 2022, while simultaneously compressing the light pattern baffle 204. Furthermore, the inner lens 203 is detachably connected to the light source assembly 205, so that light emitted by the light source assembly 205 sequentially passes through the inner lens 203, the light pattern baffle 204, and the outer lens 2021, thereby forming a low beam or a high beam.
[0052] Since the lens holder 2022 is usually made of plastic, when the light outside the lighting module 200 is refracted by the outer lens 2021, it is easy to focus on the lens holder 2022, thereby causing ablation of the lens holder 2022. Figure 8 As shown, the headlight may further include an anti-ablation sheet 206, which is pressed against the lens holders 2022 on both sides of the outer lens 2021. The anti-ablation sheet 206 may be made of metal and disposed within the focusing area of the lens holder 2022 to prevent light from outside the lighting module 200 from being focused on the lens holder 2022, thereby reducing the risk of ablation of the lens holder 2022.
[0053] In some embodiments, as Figure 8 and Figure 9 As shown, the light source assembly 205 may include a lamp board 2051 and a heat sink 2052. The lamp board 2051 is located between the inner lens 203 and the heat sink 2052, and the inner lens 203 and the heat sink 2052 may be connected by fasteners such as bolts to press the lamp board 2051. The inner lens 203 may be provided with a positioning post, and the lamp board 2051 may be provided with a positioning hole, so that the positioning post of the inner lens 203 cooperates with the positioning hole of the lamp board 2051 to achieve the installation and positioning of the inner lens 203, as shown in FIG. Figure 9 In addition, Figure 9 As shown, when positioning between the inner lens 203 and the light board 2051, it is necessary to ensure that the positioning gap is small. If the positioning gap is large, it may cause light deviation, thereby reducing or over-brightening the bright spot of the low beam zone III 400, and due to the change in focal length, Emax will be reduced, further affecting the illumination distance and illumination width, resulting in a decrease in optical performance.
[0054] In some embodiments, the light board 2051 is equipped with high-beam and low-beam LEDs. If the low-beam LEDs are offset relative to the inner lens 203, the light will deviate from the low-beam zone III 400 of the outer lens 2021, causing the low-beam zone III 400 to be excessively bright, thereby dazzling oncoming drivers. If the high-beam LEDs are offset relative to the inner lens 203, the high-beam light will likely deviate and attenuate, and the high-beam Emax value will be reduced, further reducing the illumination distance and width, resulting in a decrease in optical performance. To this end, the positioning gap t between the inner lens 203 and the light board 2051 must be no greater than 0.05 mm.
[0055] In the above embodiment, if Figure 10As shown, the light-shaped baffle 204 can be formed by stacking two metal plates of different thicknesses and connecting them together by riveting or laser welding. For ease of understanding, the two metal plates of different thicknesses are defined as a first metal plate 2041 and a second metal plate 2042, respectively. The thickness of the first metal plate 2041 is less than that of the second metal plate 2042, so that the second metal plate 2042 can increase the strength of the light-shaped baffle 204. The reflectivity of the first metal plate 2041, which is thinner, is greater than that of the second metal plate 2042. Furthermore, the first metal plate 2041 can be coated with an aluminum layer to further increase its reflectivity, thereby allowing light to be reflected from the first metal plate 2041 to be emitted from the outer lens 2021. Furthermore, the aluminum layer can protect the first metal plate 2041, thereby extending the service life of the light-shaped baffle 204. Alternatively, the second metal plate 2042 can be coated with an aluminum layer to protect the second metal plate 2042.
