Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, and more specifically, to an automotive lamp and an automobile. Background Technology

[0002] The functions of automotive exterior lighting fixtures are mainly divided into two categories: signal lights and illumination lights. Among them, automotive signal lights include turn signals, position lights, brake lights, etc., which provide signal prompts for road users. Automotive signal lights generally adopt a linear design. On the other hand, automotive illumination lights include low beam, high beam, cornering lights, etc., which provide road illumination for drivers. Automotive illumination lights are generally circular lens modules.

[0003] In recent years, with the continuous development of new energy vehicles, more and more models are using split headlights. For example... Figure 1 As shown, a split headlight design divides the headlight function into two parts: an upper part is a thin strip of signal lights, and a lower part is a circular lighting module, often resulting in a large overall size. This design requires separate manufacturing and installation, leading to cumbersome installation, large overall size, and high manufacturing costs. Summary of the Invention

[0004] The purpose of this invention is to provide an automotive lighting fixture and an automotive vehicle that can solve the problems of complicated installation, large overall size, and high manufacturing cost of split headlights in the prior art.

[0005] The embodiments of the present invention are implemented as follows:

[0006] In one aspect, this invention provides an automotive lighting fixture, comprising an integrated signal light module and a lighting module. The number of lighting modules is n, where n is a positive integer. The signal light module and the n lighting modules emit light in the same direction. The light-emitting surfaces of the signal light module and the n lighting modules are all rectangular. The signal light module and the n lighting modules are arranged side-by-side and spaced apart along a first direction. The rectangular side length of each lighting module along the first direction is less than or equal to 20 mm, and the rectangular side length of each lighting module along a second direction perpendicular to the first direction is less than or equal to 30 mm. This automotive lighting fixture solves the problems of cumbersome installation, large overall size, and high manufacturing cost associated with existing split headlights.

[0007] Optionally, the value of n is between 2 and 3. Each of the lighting modules includes an integrated low-beam optical component, a high-beam optical component, and a lens. The brightness of the low-beam spot emitted by the low-beam optical component and the high-beam spot emitted by the high-beam optical component are both 1 / n of the overall brightness of the n lighting modules. The allowable deviation of the luminous flux of the low-beam optical component and the high-beam optical component is within ±30%.

[0008] Optionally, the low beam optical component includes a low beam concentrator and a low beam light source, and the high beam optical component includes a high beam concentrator and a high beam light source. The light emitted from the low beam light source passes through the light-incident portion of the low beam concentrator and is directed to the light-emitting portion of the low beam concentrator. After being refracted by the lens, it forms a low beam pattern on the target plane. The light emitted from the high beam light source passes through the light-incident portion of the high beam concentrator and is directed to the light-emitting portion of the high beam concentrator. After being refracted by the lens, it forms a high beam pattern on the target plane.

[0009] Optionally, both the light-emitting section of the low beam concentrator and the light-emitting section of the high beam concentrator are provided with a stepped structure, and the light-emitting sections of the low beam concentrator and the high beam concentrator cooperate to form a cutoff line between light and dark.

[0010] Optionally, the materials of the near beam concentrator and the far beam concentrator are optically transparent silicone or glass, respectively.

[0011] Optionally, the low-beam light source and the high-beam light source are LED beads or lasers, respectively, with the number of low-beam light sources and high-beam light sources ranging from 2 to 5, and the luminous area of ​​the low-beam light source and the high-beam light source being less than or equal to 0.6 mm². 2 .

[0012] Optionally, the low-beam light source is an LED bead, and the high-beam light source is a laser, wherein the luminous flux of each LED bead is greater than or equal to 150 lm / pcs, and the luminous flux of each laser is greater than or equal to 300 lm / pcs.

[0013] Optionally, the lens is a plano-convex lens or a biconvex lens.

[0014] Optionally, the signal light module includes a dual-color light source.

[0015] In another aspect of this invention, a vehicle is provided, including the aforementioned automotive lighting fixtures. The number of automotive lighting fixtures is two sets, with the two sets located on opposite sides of the front of the vehicle. The signal light modules of the two sets of automotive lighting fixtures are close to each other, while the lighting modules of the two sets of automotive lighting fixtures are opposite to each other. This automotive lighting fixture can solve the problems of cumbersome installation, large overall size, and high manufacturing cost associated with existing split headlights.

[0016] The beneficial effects of the embodiments of the present invention include:

[0017] This automotive lighting system includes an integrated signal light module and a lighting module. The number of lighting modules is n, where n is a positive integer. The signal light module and the n lighting modules emit light in the same direction. The light-emitting surfaces of both the signal light module and the n lighting modules are rectangular.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] Please refer to the reference. Figures 2 to 8 This application provides an automotive lighting fixture 100, comprising an integrated signal light module 10 and lighting modules 20. The number of lighting modules 20 is n, where n is a positive integer. The signal light module 10 and the n lighting modules 20 emit light in the same direction. The light-emitting surfaces of the signal light module 10 and the n lighting modules 20 are all rectangular. The signal light module 10 and the n lighting modules 20 are arranged side-by-side and spaced apart along a first direction. The rectangular side length of each lighting module 20 along the first direction is less than or equal to 20 mm, and the rectangular side length of each lighting module 20 along a second direction perpendicular to the first direction is less than or equal to 30 mm. This automotive lighting fixture 100 can solve the problems of cumbersome installation, large overall size, and high manufacturing cost of existing split headlights.

[0035] It should be noted that, as Figure 2 As shown, the automotive lighting fixture 100 includes a signal light module 10 and a lighting module 20, wherein the signal light module 10 and the lighting module 20 are integrated to avoid the problems of cumbersome installation and high manufacturing cost of separate headlights in the prior art. Furthermore, the number of lighting modules 20 is n, where n is a positive integer. The n lighting modules 20 adopt the same structural design to ensure that there are no individual differences between each lighting module 20, thereby reducing design complexity and assembly compatibility. Regarding the actual number of lighting modules 20, those skilled in the art should be able to make reasonable selections and designs based on actual conditions; no specific restrictions are made here. For example, n can be 1, 2, 3, 4, or 5, etc. Considering the body width and front design of the vehicle 200, preferably, the value of n is between 2 and 3, that is, n can be 2 or 3.

[0036] Specifically, such as Figure 2 and Figure 3As shown, the signal light module 10 and n lighting modules 20 emit light in the same direction. The light-emitting surfaces of the signal light module 10 and the n lighting modules 20 are all rectangular (or approximately rectangular). The signal light module 10 and the n lighting modules 20 are arranged side by side and spaced apart along a first direction. The rectangular side length of each lighting module 20 along the first direction is less than or equal to 20mm, such as 10mm, 15mm, 18mm or 20mm, etc. The rectangular side length of each lighting module 20 along a second direction perpendicular to the first direction is less than or equal to 30mm, such as 15mm, 20mm, 25mm or 30mm, etc., to avoid the lighting module 20 being too large, thereby avoiding the problem of large overall size of the split headlights in the prior art.

[0037] It should be understood that since the automotive lamp 100 provided in this application is applied to the vehicle 200 to realize the functions of signal light and illumination light, the above-mentioned "same direction of light emission" refers to the front of the vehicle 200 during the vehicle's movement, the above-mentioned "target plane" refers to the road surface in front of the vehicle 200 during the vehicle's movement, the above-mentioned "first direction" refers to the horizontal direction or approximately horizontal direction, and the above-mentioned "second direction perpendicular to the first direction" refers to the vertical direction or approximately vertical direction. As long as the arrangement of the signal light module 10 and the illumination module 20 meets the actual needs of the integrated design of the automotive lamp 100, no specific restrictions are imposed here.

[0038] As described above, the automotive lighting fixture 100 includes an integrated signal light module 10 and a lighting module 20. The number of lighting modules 20 is n, where n is a positive integer. The signal light module 10 and the n lighting modules 20 emit light in the same direction. The light-emitting surfaces of the signal light module 10 and the n lighting modules 20 are all rectangular. The signal light module 10 and the n lighting modules 20 are arranged side-by-side and spaced apart along a first direction. The rectangular side length of each lighting module 20 along the first direction is less than or equal to 20 mm, and the rectangular side length of each lighting module 20 along a second direction perpendicular to the first direction is less than or equal to 30 mm. The aforementioned signal light module 10 and lighting module 20 adopt an integrated design, and the n lighting modules 20 adopt the same structural design. There are no individual differences between each lighting module 20, thereby reducing the complexity of the design and the compatibility of the assembly. This solves the problems of cumbersome installation, large overall size, and high manufacturing cost of the existing split headlights.

[0039] like Figure 4As shown, each lighting module 20 includes an integrated low-beam optical component 21, a high-beam optical component 22, and a lens 23. That is, each lighting module 20 is an integrated low-beam and high-beam module, encompassing both low-beam and high-beam functions to simplify installation and reduce manufacturing costs. In addition, each lighting module 20 should also include conventional components such as a circuit board 24 and a heat sink 25. Theoretically, the brightness of the low-beam spot emitted by the low-beam optical component 21 and the high-beam spot emitted by the high-beam optical component 22 are both 1 / n of the overall brightness of n lighting modules 20. In actual manufacturing, the allowable deviation of the luminous flux of the low-beam optical component 21 and the high-beam optical component 22 is within ±30%. Optionally, the lens 23 is a convex lens 23, such as a plano-convex lens 23 or a biconvex lens 23.

[0040] For example, such as Figure 2 and Figure 3 As shown, in this embodiment, n is 3. The low beam optical component 21 of each lighting module 20 has a full range of low beam pattern 213, and the high beam optical component 22 of each lighting module 20 has a full range of high beam pattern 223. Theoretically, the brightness of the low beam spot emitted by the low beam optical component 21 and the brightness of the high beam spot emitted by the high beam optical component 22 are both 1 / 3 of the overall brightness (or design brightness) of the three lighting modules 20. In actual manufacturing, the allowable deviation of the luminous flux of the low beam optical component 21 and the high beam optical component 22 is within ±30%.

[0041] like Figures 4 to 8 As shown, in this embodiment, the low beam optical component 21 includes a low beam concentrator 211 and a low beam light source 212, wherein the low beam light source 212 should be located at the focal point of the low beam concentrator 211. The high beam optical component 22 includes a high beam concentrator 221 and a high beam light source 222. Similarly, the high beam light source 222 should be located at the focal point of the high beam concentrator 221. The light emitted from the low beam light source 212 passes through the light-incident part of the low beam concentrator 211 and is directed to the light-emitting part of the low beam concentrator 211. After being refracted by the lens 23, it forms a low beam pattern 213 on the target plane. The light emitted from the high beam light source 222 passes through the light-incident part of the high beam concentrator 221 and is directed to the light-emitting part of the high beam concentrator 221. After being refracted by the lens 23, it forms a high beam pattern 223 on the target plane, thereby satisfying the signal light function and illumination function of the automotive lamp 100.

[0042] Specifically, such as Figure 5As shown, both the light-emitting sections of the low beam concentrator 211 and the high beam concentrator 221 have stepped structures. The stepped structure of the light-emitting section of the low beam concentrator 211 forms a low beam cutoff line. The light-emitting sections of the low beam concentrator 211 and the high beam concentrator 221 work together to form a bright and dark cutoff line, so that the bright and dark cutoff line has multiple inflection points, thereby meeting the regulatory requirements of vehicle headlight pattern 200. Optionally, the light-incident sections of the low beam concentrator 211 and the high beam concentrator 221 can be designed as columnar collimators or as cup-shaped condensers. The materials of the low beam concentrator 211 and the high beam concentrator 221 are optically transparent silicone or glass, respectively.

[0043] Optionally, the low beam light source 212 and the high beam light source 222 are LED beads or lasers, respectively. The number of low beam light sources 212 and high beam light sources 222 is between 2 and 5, for example, 2, 3, 4 or 5, preferably 3, and they are arranged in a dispersed manner. The light-emitting area of ​​low beam light source 212 and high beam light source 222 is less than or equal to 0.6 mm². 2 Preferably, the near beam source 212 is an LED lamp bead, and the far beam source 222 is a laser. The luminous flux of each LED lamp bead is greater than or equal to 150 lm / pcs, such as 180 lm / pcs, 200 lm / pcs, 250 lm / pcs, or 300 lm / pcs, etc., and the luminous flux of each laser is greater than or equal to 300 lm / pcs, such as 320 lm / pcs, 350 lm / pcs, 400 lm / pcs, or 500 lm / pcs, etc.

[0044] Optionally, the signal light module 10 includes a dual-color light source to enable the signal light module 10 to perform multiple functions, including position lights, daytime running lights, and front turn signals. For example, the dual-color light source includes white light and yellow light, with white light used as position lights and daytime running lights, and yellow light used as front turn signals.

[0045] This application embodiment also provides a vehicle 200, including the aforementioned vehicle lamps 100. The number of vehicle lamps 100 is two sets, with the two sets of vehicle lamps 100 located on opposite sides of the front of the vehicle 200. The signal light modules 10 of the two sets of vehicle lamps 100 are close to each other, while the lighting modules 20 of the two sets of vehicle lamps 100 are opposite to each other. Since the structure and beneficial effects of the vehicle lamps 100 have been described in detail in the foregoing embodiments, they will not be repeated here.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.
