Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, specifically to an automotive signal light and an automotive vehicle. Background Technology

[0002] Existing optical lens 3 structures, such as Figure 1 As shown, several significant problems exist: 1. The optical lens 3 is thick and heavy, which increases the molding time; 2. Under the structure of this optical lens 3, it is impossible to control the optical axis to move downward, and the final emitted optical axis is downward, so the distance of the emitted light is limited; 3. On the light distribution surface, the uniformity of illumination is poor and the appearance is not aesthetically pleasing. Summary of the Invention

[0003] The purpose of this invention is to provide an automotive signal light that can effectively adjust the optical axis angle and reduce the weight of the lens.

[0004] To achieve the above objectives, the main technical solution of the present invention is an automotive signal light, including a lamp housing and a light source and an optical lens disposed within the lamp housing; the optical lens is arranged between the light source and the light-transmitting surface of the lamp housing, and the light emitted by the light source is refracted by the optical lens and emitted from the light-transmitting surface in a parallel light form, and the light distribution surface of the optical lens opposite to the transparent surface is an inclined surface C; the inner part of the optical lens is partially cut and hollowed out to form an air-avoiding layer, the air-avoiding layer including a first control surface B, a second control surface A opposite to the first control surface B and a top surface, and the angle between the first control surface B and the top surface is controlled and adjusted based on the inclination of the inclined surface C.

[0005] In some instances, the cross-section of the avoidance air layer is trapezoidal, the first control surface B is an obtuse angle between the inclined surface and the top surface, and the range of the obtuse angle is adjusted according to the inclination of the inclined surface C, which is a flat surface.

[0006] In some instances, the cross-section of the air avoidance layer is U-shaped, the first control surface B and the second control surface A are parallel to each other and perpendicular to the top surface, and the tangential surface C is uniformly arranged in a stepped pattern.

[0007] In some instances, the end face of the optical lens opposite to the light source is a curved convex surface. The diverging light emitted from the light source enters through the curved convex surface and is refracted before passing through the optical lens as parallel light. The incident angle of the parallel light entering the first control surface B is controlled by the first control surface B and the second control surface A.

[0008] In some instances, the parallel light rays located between the inclined surface C and the first control surface B are inclined upward relative to the parallel light rays located in the arcuate convex surface and the clearance air layer; after being refracted through the inclined surface C and the light-transmitting surface of the lamp housing in sequence, they are emitted horizontally, and the height of the horizontally emitted light rays is higher than the height of the light source when it enters the arcuate convex surface.

[0009] An automobile includes a body and the aforementioned vehicle signal lights disposed in the body.

[0010] By employing the above technical solutions, this invention achieves the following effects:

[0011] 1. Cutting and hollowing out the internal part of the optical lens to form an air-avoiding layer has the advantage of effectively reducing the weight of the optical lens, thereby reducing the weight of the entire signal light; 2. By adjusting the tilt of the first control surface B or changing the surface texture of the tilt surface C, the optical axis (light beam) can be effectively raised. Attached Figure Description

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0017] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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. Therefore, the above terms should not be construed as limiting this invention.

[0018] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0019] Example 1:

[0020] Referring to the accompanying drawings of this invention Figures 1 to 3 As shown, a preferred embodiment of the present invention is described for a car signal light, the car signal light including a lamp housing and a light source 4 and an optical lens 3 disposed within the lamp housing; the optical lens 3 is arranged between the light source 4 and the light-transmitting surface of the lamp housing, the light 7 emitted by the light source 4 is refracted by the optical lens 3 and emitted from the light-transmitting surface in a parallel light form, the light distribution surface of the optical lens 3 opposite to the transparent surface is an inclined surface C; the optical lens 3 is partially cut and hollowed out to form an air-avoiding layer 5, the air-avoiding layer 5 including a first control surface B and a... The first control surface B is opposite to the second control surface A and the top surface 6. The angle between the first control surface B and the top surface 6 is controlled and adjusted based on the inclination of the inclined surface C. The lamp housing includes a light-transmitting lampshade 1 and a rear shell 2. The light-transmitting surface refers to the lampshade 1. After the lampshade 1 and the rear shell 2 are connected and fixed, they can form a sealed chamber. The light source 4 and the optical lens 3 are installed in the sealed chamber. In some other embodiments, the sealed chamber can be filled with an inert gas. The inclined surface C of the optical lens 3 faces the light-transmitting surface, and the existing optical lens 3 structure is as follows: Figure 1 As shown, several significant problems exist: 1. The optical lens is thick and heavy, resulting in a longer molding time; 2. Under the structure of this optical lens 3, it is impossible to control the optical axis to move downwards, and the final emitted optical axis is downwards, thus limiting the distance of the emitted light 7; 3. On the light distribution surface, the uniformity of illumination is poor, and the appearance is not aesthetically pleasing. Therefore, the main innovation of this technical solution is: 1. Cutting and hollowing out the internal part of the optical lens 3 to form an air-avoiding layer 5. The advantage of this setting is that it can effectively reduce the weight of the optical lens 3, thereby reducing the weight of the entire signal light; 2. By adjusting the tilt of the first control surface B or changing the surface texture of the tilt surface C, the optical axis (light 7) can be effectively raised.

[0021] Specifically, this technical solution demonstrates two implementation methods, such as... Figure 2As shown, one aspect is that the cross-section of the air-avoidance layer 5 is trapezoidal. The first control surface B is an obtuse angle between the inclined surface and the top surface 6. The range of the obtuse angle is adjusted according to the inclination of the inclined surface C. The inclined surface C is a flat surface. In this embodiment, the inclined surface C does not need to be set with patterns or textures. The optical axis angle is mainly set by cutting and controlling the inclination of the first control surface B, thus completely preserving the shape of the car manufacturer without modification. At the same time, since the air-avoidance layer 5 can effectively reduce the weight of the optical lens 3, the molding time can be shortened. In addition, in this embodiment, by setting the textured first control surface B on the opposite side surface of a portion of the optical lens 3, even if the optical path length is short, a uniform appearance can be achieved, ultimately achieving a uniform, three-dimensional, matte, and crystal-like design.

[0022] Another type is where the cross-section of the avoidance air layer 5 is U-shaped, such as... Figure 3 As shown, the first control surface B and the second control surface A are parallel to each other and perpendicular to the top surface 6. The beveled surface C is uniformly arranged in a stepped pattern. This scheme mainly relies on the stepped pattern to make the emitted optical axis horizontal. Compared with the traditional method, it can effectively raise the optical axis and reduce the weight of the optical lens 3 itself. However, compared with the previous scheme, its disadvantage is that the optical axis cannot be adjusted and the aesthetics are poor.

[0023] The end face of the optical lens 3 opposite to the light source 4 is an arc-shaped convex surface. The diverging light 7 emitted by the light source 4 enters from the arc-shaped convex surface and is refracted before passing through the optical lens 3 as a parallel light 7. The incident angle of the parallel light 7 entering the first control surface B is controlled by the first control surface B and the second control surface A. In the first embodiment, the optical axis emission process is as follows: the parallel light 7 located between the inclined surface C and the first control surface B is inclined upward relative to the parallel light 7 located in the arc-shaped convex surface and the clearance air layer 5; after being refracted through the inclined surface C and the light-transmitting surface of the lamp housing in sequence, it is emitted horizontally. The height of the horizontally emitted light 7 is higher than the height of the light source 4 when it enters the arc-shaped convex surface.

[0025] This embodiment provides a car (illustrated but not shown), which includes a body and the car signal lights mentioned in Embodiment 1. The car signal lights are installed in the body; when the car is turning, parking, or performing other operations, it can enable oncoming vehicles at a greater distance to notice it immediately and take corresponding safe driving measures, thereby reducing traffic accidents.

[0026] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention.

[0027] The objective of this invention has been fully and effectively achieved. The function and structural principles of this invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of this invention may have any variations or modifications.
