[0028] 3 step surface 4 internal mirror DETAILED DESCRIPTION
[0029] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation modes described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the specific implementation modes described below.
[0030] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "provided with", "installed", and "connected" should be understood in a broad sense. For example, the connection can be a direct connection or an indirect connection through an intermediate medium, a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate connection member, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0031] The directions or positional relationships indicated by the directional words "rear", "front", "left", "right", "both sides", etc. are based on the directions or positional relationships shown in the drawings. For example, the direction indicated by the directional word "front" is the normal driving direction of the vehicle. The description of the directions or positional relationships of the headlight optical elements and headlight modules and their components of the utility model is consistent with the installation directions in actual use. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as a limitation on the utility model; the directional terms of the utility model should be understood in conjunction with the actual installation status.
[0032] See also Figure 1In a first aspect, the utility model provides an optical component, which includes a light source 1 and a reflective component, wherein the reflective component includes at least one reflector 2, a real focus 21 is formed on one side of the reflector 2, and a virtual focus 22 is formed on the other side of the reflector 2, the real focus 21 is arranged close to the light source 1 and is located within a preset distance range of the light source 1, and the distance from the real focus 21 to the reflector 2 is smaller than the distance from the virtual focus 22 to the reflector 2.
[0033] It should be noted that when the optical assembly provided by the utility model is in use, light is emitted from the light source 1 and then reflected by the reflector 2. Figure 1 As shown, after reflection, the light is emitted in the direction indicated by the arrow, but an image is formed at the virtual focus 22, that is, an image is formed behind the reflector 2. It is understandable that if the reflective surface of the reflector 2 faces the front of the vehicle, people will not feel the light is glaring when looking at the optical component, and will feel that the light they see is far away from them, achieving a tunnel-like visual effect. In addition, the optical component mainly uses the light source 1 and the reflector 2, so the structure is simple and the space occupied is small. The real focus 21 of the reflector 2 is set at a position close to the light source 1 and within the set range of the light source 1. First, it can be easily installed and there is a certain error allowable range during installation. In addition, the closer the real focus 21 is to the light source 1, the clearer the image at the virtual focus 22 will be, thereby improving the clarity of the image.
[0034] It should be noted that the reflector 2 may be a hyperbolic reflector, which utilizes the principle of hyperbolic reflection to improve lighting effects. The shape and curvature of the hyperbolic surface may be set according to actual usage conditions, so that light can be better focused and scattered, thereby improving driving safety.
[0035] It should also be noted that the "real focus 21" and the "virtual focus 22" are two focal points located on the optical axis of the reflector 2 and meet the equal optical path condition, wherein the "virtual focus 22" is the imaging point and forms a virtual image. In addition, the "distance from the real focus 21 to the reflector 2 is smaller than the distance from the virtual focus 22 to the hyperbolic reflector" mentioned in the above technical solution can be understood as that the distance from the real focus 21 to any point on the reflective surface of the reflector 2 is smaller than the distance from the virtual focus 22 to the point, such as Figure 2 As shown in FIG. 1 , as a specific embodiment of the present invention, the specific embodiment uses three reflectors 2 to form a reflective element, namely, reflector 2a, reflector 2b and reflector 2c, wherein the real focal points 21 of the three reflectors 2 are all located within the set range of the light source 1, and the light is emitted from the light source 1, such as Figure 2As shown, refraction is performed in the direction indicated by the arrow, wherein the extension lines of the reflected light rays of each reflector 2 intersect at one point, which is the virtual focus 22 of the reflector 2. Therefore, the virtual focus 22 of the reflector 2a, the reflector 2b and the reflector 2c are respectively the virtual focus 22a, the virtual focus 22b and the virtual focus 22c. Taking the reflector 2a as an example, the distance from the real focus 21 to any point on the reflecting surface of the reflector 2a is less than the distance from the virtual focus 22a to the point.
[0036] Further, as a specific implementation of the reflective component in the optical component provided by the utility model, as Figure 1 and Figure 2 As shown, the reflective assembly may not only use one reflector 2, but may also include several reflectors 2, such as Figure 2 As shown, three reflectors 2 can be set, or two, four, etc. It should be noted that these reflectors 2 need to be connected in sequence, and the real focus 21 of each reflector 2 needs to be set close to the light source 1 and within the set distance range of the light source 1. In this way, the reflectors 2 can be set according to the specific use environment. If you want to have several images, you can set several reflectors 2 accordingly, which can not only achieve a tunnel-like lighting effect, but also meet the personalized requirements of contemporary young people.
[0037] It should be noted that the “located within the set distance range of the light source 1” in the above technical solution can be understood as a sphere with the light source 1 as the center and a radius as a preset value, and the real focus 21 of each reflector 2 is located in the internal area of the sphere. Preferably, the preset radius value is 5 mm, which can be understood as that the real focus 21 of each reflector 2 is located within a range of less than or equal to 5 mm from the light source 1.
[0038] Specifically, if a plurality of reflectors 2 are provided, the reflectors 2 may be sequentially connected in the vertical direction and / or in the horizontal direction. It is understood that if a plurality of reflectors 2 are sequentially connected in the vertical direction, the structure is similar to Figure 2As shown, the reflection component formed by the combination of these reflectors 2, after reflecting the light from the light source 1, the formed several images are arranged in the vertical direction, but it should be noted that they are only arranged in the vertical direction, but the several images are not necessarily on a vertical straight line; if multiple reflectors 2 are connected in sequence along the horizontal direction, then the reflection component formed by the combination of these reflectors 2, after reflecting the light from the light source 1, the formed several images are arranged in the horizontal direction, but it should be noted that they are only arranged in the horizontal direction, but the several images are not necessarily on a horizontal straight line; if multiple reflectors 2 are arranged along the vertical direction, and there are still several reflectors 2 arranged along the horizontal direction, then the reflection component formed by the combination of these reflectors 2, after reflecting the light from the light source 1, the images can be arranged in a matrix.
[0039] In addition, the specific settings of the reflective components can be set according to actual usage requirements and the preferences of the vehicle driver. For example, several reflectors 2 can be arranged and connected in a circle, so that the visual effect of the image projection is in the shape of a circular ring. A shading plate can also be set in front of each reflector 2, and each shading plate can be controlled and set according to the specific pattern to be formed after imaging. Then, the reflectors 2 that need to be used are selected, and the reflectors 2 that do not need to be used are blocked by the shading plates. In this way, the formation of an imaging pattern with a tunnel-like visual effect can be achieved, which is more personalized.
[0040] Furthermore, if several reflectors 2 are arranged to form a reflective assembly, then two adjacent step surfaces 3 are transitionally connected via the step surface 3. The step surface 3 can connect the several reflectors 2 to form an integrated structure, while also preventing the two adjacent reflectors 2 from interfering with each other when reflecting the corresponding parts of the light and generating stray light.
[0041] Furthermore, in order to prevent the step surface 3 from being unable to refract after receiving the light, an aluminum coating is provided on the working surface of the step surface 3 facing the light source 1, so that the step surface 3 also has a reflective function. In this way, it is prevented that after the reflective component reflects the light, part of the light will actually form black spots, affecting the subsequent imaging effect.
[0042] It should be noted that an aluminum coating is provided not only on the step surface 3 but also on the working surface of the reflector 2 facing the light source 1. The aluminum coating refers to a layer of aluminum film coated on the step and the substrate surface of the reflector 2 by a vacuum coating method. The aluminum film can protect the surface of the reflector to prevent the mirror from being oxidized and corroded by chemical substances such as water vapor and air, thereby increasing the service life of the reflector.
[0043] Furthermore, if Figure 1 and Figure 3 As shown, as a specific embodiment of the present invention, the optical assembly provided in the first aspect of the present invention also includes an endoscope 4, and the light source 1 is arranged between the endoscope 4 and the reflection assembly. After the light is emitted from the light source 1, it is reflected by the reflection assembly and then projected toward the endoscope 4. The endoscope 4 can focus the projected light, so that the light can be clearer after being reflected by the reflection assembly to form an image.
[0044] Furthermore, if Figure 3 As shown, as a specific embodiment of the endoscope 4, the light-emitting surface of the endoscope 4 is a curved light-emitting surface, and the side facing away from the light source 1 protrudes outward, and an optical pattern is formed on the curved light-emitting surface. The curved light-emitting surface can converge the light, and the optical pattern can homogenize the light to make the projected image clearer.
[0045] In order to better understand the technical solution and use method of the present invention, the preferred embodiments are described below in combination with relatively comprehensive preferred technical features.
[0046] A first aspect of the present invention provides an optical component, see Figures 1 to 3 , including a light source 1, a reflection component and an inner mirror 4, wherein the light source 1 is arranged between the reflection component and the inner mirror 4, the light emitted by the light source 1 is reflected by the reflection component and then projected from the inner mirror 4, the reflection component includes a plurality of reflectors 2, these reflectors 2 are connected in sequence, and two adjacent reflectors 2 are connected by steps, an aluminum coating is arranged on the working surface of the step surface 3 facing the light source 1, the real focus 21 of each reflector 2 coincides with the light source 1, and the distance between the virtual focus 22 of each reflector 2 and the reflector 2 is smaller than the distance between the real focus 21 and the reflector 2, and the light emitting surface of the light distribution mirror is a curved light emitting surface, and an optical pattern is formed on the light emitting surface.
