Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle lights, and particularly relates to an optical module, a vehicle light, and a vehicle. Background Technology

[0002] Traditional car high beams, while providing a longer illumination distance at night, can easily dazzle other road users, creating safety hazards. Adaptive High Beam (ADB) technology was developed to address this problem. It relies on intelligent technology to precisely optimize the lighting effect of high beams.

[0003] The conventional design of ADB systems on the market is based on reflective or condenser lighting structures, using LEDs arranged in a regular pattern, and then combined with lenses to form a regular light pattern on the road surface.

[0004] While existing ADB (Augmented Radiator) technologies can achieve anti-glare and dynamic lighting, reflective ADB solutions require the reflector to be curved to effectively focus light, and the LEDs can only be placed laterally. This results in a large lateral size for the optical module, making it difficult to meet the space constraints of current automotive headlight designs. Concentrator-type ADB solutions suffer from problems such as large lens sizes. Furthermore, module designs have limitations in balancing optical performance and aesthetics, failing to meet users' dual demands for both beauty and high performance. Utility Model Content

[0005] The purpose of this invention is to provide an optical module, a car light, and a vehicle that combines a condenser with a lens with a vertically narrow and elongated opening to achieve a vertically narrow and elongated optical module and to realize pixelated lighting function.

[0006] To solve the above problems, the technical solution of this utility model is as follows: An optical module, comprising: Multiple optical units arranged vertically, each optical unit including a light source, a condenser, and a lens unit; The concentrator includes multiple concentrating units arranged laterally, and the light source is arranged correspondingly to the concentrating units; The lens unit is formed as a single piece, and the light-emitting surfaces of multiple lens units are connected as a plane or a curved surface with the same curvature. The lens unit includes at least one lens; The light emitted by the light source passes through the corresponding focusing unit and the lens unit to form multiple pixels, and the multiple pixels combine to form a light pattern.

[0007] According to one embodiment of the present invention, the light-concentrating unit is a plano-convex lens, wherein the light-incident surface of the light-concentrating unit is a plane and the light-excising surface is a forward-convex curved surface.

[0008] According to one embodiment of the present invention, the light source is located 0.1mm to 5mm behind the light incident surface of the focusing unit.

[0009] According to one embodiment of the present invention, a plurality of the light-concentrating units are formed into a single unit.

[0010] According to one embodiment of the present invention, the condenser further includes an accompanying lighting structure, which is independently configured with respect to the condenser unit and is used to be lit up in the low beam illumination mode so that the lens unit is in a lit state.

[0011] According to one embodiment of the present invention, the light-concentrating unit includes a plurality of light-concentrating units of different sizes to form pixels of different sizes.

[0012] According to one embodiment of the present invention, each of the light-concentrating units is provided with a plurality of light sources.

[0013] According to one embodiment of the present invention, the lens unit includes an inner lens and an outer lens.

[0019] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further explanation of the optical module, vehicle light, and vehicle proposed in this utility model.

[0020] Please refer to Figures 1 to 3 This embodiment provides an optical module comprising multiple vertically arranged optical units 1. Each optical unit 1 includes a light source 2, a condenser 3, and a lens unit 4. The condenser 3 includes multiple horizontally arranged condensing units 5. The lens unit 4 is formed as a single piece, and its light-emitting surface is either a plane or a curved surface with a consistent curvature. The lens unit 4 includes at least one lens 6. The light source 2 and the condensing units 5 are correspondingly arranged. The light emitted from the light source 2 passes through the condensing units 5 and the lens unit 4, forming multiple pixels. The pixels combine to form a light pattern.

[0021] This optical module can adaptively switch the light pattern under different traffic scenarios by controlling the brightness of the light source. In particular, the module's shape with a narrow horizontal opening breaks through the design limitations of traditional optical modules with large horizontal dimensions, enabling the flattening and personalization of headlights.

[0022] For details, please refer to Figure 4The lens unit 4 includes an inner lens 7 and an outer lens 8. The lens unit 4 adopts a two-piece lens design, which can reduce the overall thickness of the lens, save costs, reduce processing difficulty, and reduce part injection molding time. At the same time, it increases the light-adjustable optical surface, reduces the difficulty of light adjustment, and improves the efficiency of part development.

[0023] The light-emitting surface of the outer lens 8 can be a plane or a curved surface with uniform curvature. This design ensures that the light-emitting surfaces of multiple lens units 4 maintain a consistent shape when forming a single unit, eliminating visual differences in the module's appearance and achieving a unified and aesthetically pleasing effect. The remaining optical surfaces of the lens unit 4, namely the light-incident surface of the outer lens 8 and the light-emitting and light-incident surfaces of the inner lens 7, can be either planes or curved surfaces; there are no restrictions here, allowing for adjustment of the light source as needed. By combining various different surface shapes, the light-incident surface of the outer lens 8 and the light-emitting and light-incident surfaces of the inner lens 7 can adjust the transmission direction and diffusion of light after passing through the primary optical element, compensating for optical aberrations (such as spherical aberration and dispersion), and achieving the desired light shape and a more uniform light distribution. It should be noted that a curved surface with uniform curvature refers to a surface where there are no obvious steps or drops when multiple curved surfaces are joined. For example, the joint of multiple curved surfaces can form a cylindrical surface with a straight cross-section along the vertical or horizontal direction, or a single smooth curved surface.

[0024] Lens unit 4 can also be a single-piece lens. Using a single-piece lens in lens unit 4 can reduce the relative tolerances between parts, thereby controlling the accuracy of the optical system. The light-emitting surface of the single-piece lens can be a plane or a curved surface with uniform curvature. The shape of the light-incident surface of the single-piece lens is not limited, so that the lens unit can adjust the light.

[0025] In this embodiment, the light-collecting unit 3 includes multiple light-collecting units 5 of different sizes to form pixels of different sizes. Please refer to... Figure 5 The focusing unit 5 on one side is larger than the other focusing units 5. In the light pattern obtained by this module, the corresponding pixels can be located at the edge of the light pattern, increasing the width of the light pattern. Please refer to the effect. Figures 6 to 8 .

[0026] The focusing unit 5 can be arranged in a matrix of single row and multiple columns or in a matrix of multiple rows and multiple columns. The light source 2 behind each focusing unit 5 is individually addressed, subdividing the high beam illumination area into multiple illumination areas. When the vehicle sensor system detects an oncoming vehicle, it turns off the light source in the corresponding area to realize the adaptive high beam function.

[0027] Preferably, please refer to Figure 9 Each focusing unit 5 can be equipped with multiple light sources 2 to increase the luminous flux. These light sources 2 can be LEDs. For example, a single focusing unit can use 2-4 LEDs in a reused design.

[0028] The focusing unit 5 can be in the form of a small lens or a light-converging cup, or other transparent components that converge light. When the focusing unit 5 is in the form of a small lens, it can be a plano-convex lens, wherein the light-incident surface of the focusing unit 5 is a plane, and the light-excising surface is a forward-convex curved surface. Of course, the focusing unit 5 can also be a plano-convex, biconvex, concave-convex, or concave-plano lens. The focusing unit 5 is preferably a plano-convex lens, which is simpler in structure and has higher luminous efficiency than the light-converging concentrator with a light-converging cup structure used in the prior art. Under the same light utilization rate, the distance between the light source 2 and the light-incident surface of the focusing unit 5 can be appropriately increased to improve the heat dissipation effect of the vehicle lamp module. The light source 2 is located 0.1mm to 5mm behind the light-incident surface of the focusing unit 5, and this distance is preferably 0.5mm. Moreover, compared with a focusing unit with a convex light-incident surface, the light-incident surface of the focusing unit is a plane, and the light rays incident on this light-incident surface are less likely to undergo total internal reflection, further improving the luminous efficiency.

[0029] Further, please see Figure 10 Multiple light-concentrating units 5 can be formed into a single unit, reducing installation difficulty and tolerance, and improving the accuracy of the light pattern formed by pixel combination.

[0030] When the optical module is used for high beam lighting, the condenser 3 also includes an accompanying lighting structure 9. By setting the accompanying lighting structure 9, the accompanying lighting structure 9 is lit up in the low beam lighting mode, that is, when the condenser unit 5 is not working, so that the lens unit 4 corresponding to the condenser unit 5 is lit up. That is, in the low beam lighting mode, all lens units 4 are lit up and there are no dark areas, and the module looks more beautiful when lit up.

[0031] In summary, this optical module breaks away from the conventional practice of arranging optical units horizontally in traditional optical modules. It adopts a vertically stacked optical unit architecture, achieving a narrow horizontal opening to meet the design requirements of a flatter and slimmer headlight. It flexibly expands the number of pixels in the vertical dimension, achieving multi-pixel zone lighting without increasing the horizontal size, adapting to the vertical spatial layout of different vehicle lights. Furthermore, the vertically narrow and long lens opening forms a unique visual feature, breaking away from the image of traditional optical modules that are wide and bulky or horizontally narrow and long, and realizing personalized and differentiated lighting designs.

[0032] This application also provides a vehicle light, including the above-mentioned optical module, which has the same technical effects as the optical module.

[0033] This application further provides a vehicle including the headlight, which has the same technical effect as the headlight.

Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
