Technical Field

[0001] The utility model relates to a vehicle lamp, and more specifically, to an optical element. In addition, the utility model also relates to a vehicle lamp module and a vehicle lamp including the optical element. Background Art

[0002] As a commonly used light source for current vehicle lamps, LED has the advantages of fast response, low energy consumption, and stable chromaticity. With the increasingly diverse lighting environments that current vehicle lamps need to face, the functional requirements for vehicle lamps and the color requirements for light are also getting higher and higher.

[0003] In order to endow vehicle lamps with multiple functions, multiple different lamps are often arranged on the vehicle body to meet the lighting requirements of different functions. Although this arrangement endows the vehicle lamp with more functions, with the current trend of vehicle bodies becoming flatter in the market, this arrangement not only increases the production cost, but also each function requires a large amount of space on the vehicle body, which cannot meet the development trend of current automobiles.

[0004] Therefore, it is necessary to design a new type of optical element with color matching function. Summary of the Utility Model

[0006] To solve the above technical problem, in the first aspect of the utility model, an optical element is provided, which includes a plurality of light condensing structures, and at least one of the light condensing structures is configured with a color matching structure. After the light passes through the color matching structure, the projection color of the light can be changed.

[0007] Further, the plurality of light condensing structures are formed into at least one row. A single light condensing structure is sequentially formed with a light incident portion, a light passing portion, and a light emitting portion along the light propagation direction. The light enters from the light incident portion, passes through the light passing portion, and then exits through the light emitting portion.

[0008] Further, the color matching structure is integrally formed or configured on the light incident portion of a single light condensing structure, so that the light enters the light incident portion after passing through the color matching structure.

[0034] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model, and the protection scope of the present utility model is not limited to the following specific embodiments.

[0035] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "arrangement", "provided with", "assembly", and "layout" should be understood in a broad sense. For example, the connection can be a direct connection or an indirect connection through an intermediate medium, which can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate connecting member, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] In the present utility model, in the following description, some orientation terms involved in clearly explaining the technical solution of the present application, such as "upper", "lower", "left", "right", etc., are based on the normal use orientation of the optical element. "Front" refers to the direction in which the light exits, "rear" refers to the direction opposite to "front", and "upper" and "lower" refer to the orientation in the vertical direction after the optical element is assembled on the vehicle. The terms are based on the direction or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0037] See Figures 1 to 2 , the first aspect of the present utility model provides an optical element, including a plurality of light condensing structures 1, wherein at least one light condensing structure 1 is configured with a color matching structure 2 so that after the light passes through the color matching structure 2, the projection color of the light can be changed.

[0038] The structure of the present utility model is simple. The optical element is formed by combining a plurality of light condensing structures 1, and the color of the light is changed through the color matching structure 2. In this way, the optical element can be configured according to different functional requirements of the vehicle lamp, and different lighting functions can be realized with different colors, integrating multiple functions to form a combined overall structure. On the one hand, it can reduce the production and manufacturing costs, and on the other hand, it can also reduce the volume of the vehicle lamp and the occupied body space.

[0039] It should be noted that the "lighting function" includes at least one of the functions of the autonomous driving marker lamp (ADS) and the functions of the headlamp and the tail lamp. The optical element provided by the present utility model integrates these functions and can minimize the installation space of the functional lighting device on the vehicle body.

[0040] Furthermore, as a specific implementation manner of the present utility model, see Figure 4, A single light - concentrating structure 1 without a color - matching function includes a light - incident part 101, a light - transmitting part 102, and a light - emitting part 103 formed in sequence along the light - propagation direction. Among them, light enters from the light - incident part 101, passes through the light - transmitting part 102, and then exits through the light - emitting part 103. Among them, the light - concentrating structure 1 can be an integrally - formed structure and is made of transparent polycarbonate (PC) material or polymethyl methacrylate (PMMA) material. Polycarbonate (PC) material, also known as PC plastic, has good heat - aging resistance and molding processability, which can extend the service life of the light - concentrating structure 1; Polymethyl methacrylate (PMMA) material, also known as acrylic or plexiglass, has the advantages of high transparency and low price, which is conducive to the propagation of light.

[0041] It should be noted that, referring to Figure 1 , Figure 2 , Figure 6 and Figure 7 , as some specific embodiments of the present utility model, the light - concentrating structure 1 can be a long - straight light concentrator, and the light - incident part 101 of the light - concentrating structure 1 can be a light - collecting cup with an inner - concave cavity, and the bottom of the inner - concave cavity is formed as an outer - convex curved surface. Such a setting can enhance the light - concentrating effect and avoid light loss. In addition, the light - concentrating structures 1 provided by the present utility model are arranged in at least one row in sequence. For the convenience of processing, several light - concentrating structures 1 can be integrally - formed parts. Since the light - concentrating structure 1 is a light concentrator, even if several light - concentrating structures 1 are integrally - formed parts, it does not affect the installation of the color - matching structure 2.

[0042] Furthermore, as a specific embodiment of the present utility model, the color - matching structure 2 is integrally - formed or disposed on the light - incident part 101 of a single light - concentrating structure 1, so that after the light first passes through the color - matching structure 2 to change its color, it then enters the light - incident part 101 and is propagated and projected by the light - concentrating structure 1. Referring to Figure 3 , as a preferred embodiment of the present utility model, the color - matching structure 2 can be directly set as the light - incident part 101 of the light - concentrating structure 1 and is integrally - formed with the light - concentrating structure 1. In this way, not only is the processing convenient, but also the installation steps are saved, and the installation efficiency is accelerated.

[0043] Furthermore, as another specific embodiment of the present utility model, the color - matching structure 2 can be integrally - formed or disposed on the light - transmitting part 102 of a single light - concentrating structure 1. Specifically, it can be located at the place where the light - incident part 101 contacts the light - transmitting part 102, or in the middle area of the light - transmitting part 102, or at the place where the light - transmitting part 102 contacts the light - emitting part 103, so as to be able to change the color of the light passing through the light - concentrating structure 1.

[0044] Further, as other specific embodiments of the present utility model, the color matching structure 2 can be integrally formed or disposed on the light-emitting portion 103 of the light condensing structure 1. For example, the color matching structure 2 directly replaces the light-emitting portion 103 of the light condensing structure 1, or the light enters the color matching structure 2 after passing through the light-emitting portion 103. In this way, the light can be homogenized when propagating inside the light condensing structure 1, and then the color conversion is performed.

[0045] It should be noted that in the above-mentioned some specific embodiments and preferred embodiments, the color matching structure 2 can be a separate accessory disposed on the light condensing structure 1 or integrally formed with the light condensing structure 1. Secondly, there are many specific structural forms of the color matching structure 2. For example, it can be formed into a cup-shaped structure with an inner concave cavity at the light incident end 201, and the bottom of the inner concave cavity is formed into an outer convex curved surface. When set in this way, it can be used as the light incident portion 101 of the light condensing structure 1; it can also be a curved surface lens disposed on the light passing portion 102 or the light-emitting portion 103. In addition, if the color matching structure 2 is a separate accessory, it can also be a light-transmitting plate with a color that can transmit light. The light-transmitting plate is inserted into the required position to complete the change of the light color. Moreover, a rotating device can be added, and light-transmitting plates of different colors are disposed on the rotating device, and the color is changed by rotation to cooperate with the needs of the vehicle lamp. It can be understood that these structural forms are all for enabling the light to be well converged while changing the color and avoiding the loss of light.

[0046] It should also be noted that the color matching structure 2 can be made of polycarbonate (PC) material or polymethyl methacrylate (PMMA) material. Both of these materials have good transparency, which is convenient for the propagation of light. When the color of the light needs to be changed, the color matching structure 2 can be made into the required color, such as yellow, white, blue or red. Specifically, it can be set according to different functional requirements of the vehicle lamp. Further, the color matching structure 2 realizes the ADS function. For example, when the light source color is white, the color matching structure 2 is blue-green to realize the function of the automatic driving logo vehicle lamp.

[0047] Further, as a specific implementation manner of the present utility model, as Figure 5 and Figure 6 shown, an optical pattern is further formed on the light-emitting surface 1031 of the light-emitting portion 103 of the light condensing structure 1. The optical pattern can optimize the lighting effect and make the light propagation more uniform.

[0048] It should be noted that Figure 5 only as a specific embodiment in the present utility model, for the specific structural form of the optical pattern, it can be as Figure 6The fish-eye shape shown can also be other shapes, which can be specifically set according to the specific usage environment. The optical element provided in the first aspect of the present invention has a simple structure. A plurality of condensing structures 1 are combined together in a combined form to form an optical element. And a color matching structure 2 is provided on a part of the condensing structures 1 to be able to change the color of the light passing through, so as to meet the color requirements of different functions of vehicle lights, integrate different vehicle light functions required by the vehicle, reduce the space occupied by the vehicle lights on the vehicle body, reduce the production and manufacturing costs, and also improve the installation efficiency.

[0049] See Figure 1 and Figure 7 , the second aspect of the present invention provides a vehicle lamp module, which includes a light source 3, a projection lens, and the optical element provided in the first aspect. The light source 3 is arranged in one-to-one correspondence with the condensing structure 1. The light emitted by the light source 3 passes through the condensing structure 1 and then is emitted through the projection lens.

[0050] The optical element in this vehicle lamp module has a simple structure and can integrate different lighting functions required by the vehicle, reduce the space occupied by the vehicle lights on the vehicle body, reduce the production and manufacturing costs, and also improve the installation efficiency. It should also be noted that the light source 3 is an LED, and the LED has the advantages of fast response, low energy consumption, and stable chromaticity.

[0051] The third aspect of the present invention provides a vehicle lamp, which includes the vehicle lamp module provided in the second aspect. This vehicle lamp occupies a small space on the vehicle body and has strong functionality.

[0052] In the description of the present invention, the description referring to terms such as "one embodiment", "some embodiments", "a specific implementation manner", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In the present invention, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0053] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0054] In addition, it should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods.

[0055] In addition, any combination can be made among the various different embodiments of the present utility model, as long as it does not violate the idea of the present utility model, and it should also be regarded as the content disclosed by the present utility model.
