Description

Technical Field

[0001] This utility model relates to the field of optical design technology, and in particular to an optical structure that can achieve a dazzling visual effect. Background Technology

[0002] With the rapid development of the automotive industry, the optical solutions and lighting effects of automotive lights have also seen more diverse and unique design requirements. In the past two years, the dazzling effect of lighting up like a starry sky has caught people's attention due to its unique lighting characteristics, attracting more attention from OEMs. As a result, many car manufacturers have put forward requirements for the dazzling lighting effects of certain functions of automotive lights.

[0003] However, due to the extremely high processing requirements and difficulty of its patterned surface, some optical solutions encountered numerous difficulties in the initial design stage. Previous solutions typically used direct LED illumination with a dazzling patterned effect on the light-emitting surface, which often limited the flexibility of the vehicle headlight installation space. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the limitation of the plasticity of the installation space of the car lamp due to the pattern on the light-emitting surface of the LED direct light, this utility model provides an optical structure that can achieve a brilliant visual effect. By setting a special pattern on the reflective surface to achieve a brilliant effect, the reflective surface can be adapted to the placement of light sources in different positions, thereby improving the plasticity of the installation space of the car lamp.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an optical structure that can achieve a bright visual effect, including a thick-walled component, wherein the width direction of the thick-walled component is set as the X direction and the height direction of the thick-walled component is set as the Z direction, and the length direction of the thick-walled component is set as the Y direction.

[0006] The thick-walled component includes at least one reflective surface, which is located at one end of the thick-walled component. The inner side of the reflective surface is at least partially provided with a special pattern, which randomly reflects the light rays incident upon it. Thus, the light rays are randomly incident, shining on the reflective surface at any angle. The reflection angles at the special pattern are different, thereby achieving a dazzling visual effect when lit. By setting the reflective surface, the restrictions on the placement of LEDs are reduced, thereby improving the flexibility of the vehicle headlight installation space.

[0007] Furthermore, the special pattern includes multiple irregular polygons, which are randomly distributed without overlapping and have varying areas. Thus, multiple irregular polygons are connected to form a special reflective portion. When light shines on the special reflective portion at any angle, the angle of reflection is different, thereby achieving a dazzling visual effect of illumination.

[0008] Furthermore, the special pattern includes multiple star-shaped patterns, which are arranged randomly with their center points not overlapping. The star-shaped patterns are interspersed with adjacent star-shaped patterns. As a result, the multiple star-shaped patterns have different distribution densities on the reflective surface, and the interspersed star-shaped patterns form special reflective portions. When light shines on these special reflective portions at any angle, the angle of reflection is also different, thus achieving a dazzling visual effect when illuminated.

[0009] Furthermore, the reflective surface is vacuum-coated; thereby ensuring that the inner side of the reflective surface can perform diffuse reflection.

[0010] Furthermore, the overall shape of the reflecting surface is planar, parabolic, hyperboloid, or freeform.

[0011] Furthermore, to ensure the integrity of the reflection level, the end face of the first reflecting surface intersects with the plane formed by the X and Y directions, and the intersection angle is an obtuse angle. The first reflecting surface is set obliquely upward; thus, it is ensured that the first reflecting surface performs total internal reflection of the incident light.

[0012] Furthermore, the thick-walled component also includes a light-emitting surface and a light-incident surface. The light-incident surface is located on one side of the first reflecting surface, and the light-emitting surface is located at the other end of the thick-walled component. The light-emitting surface is located on a plane formed by the Z and Y directions. Thus, the light reflected by the first reflecting surface is emitted from the light-emitting surface.

[0013] Furthermore, the outer side of the light-emitting surface is provided with patterns or textures.

[0014] Furthermore, the inner side of the first reflective surface is provided with multiple non-directional protrusions, which are irregularly arranged; thus, the protrusions on the first reflective surface adjust the angle at which the corresponding special pattern intersects with the first reflective surface, so that the incident light forms reflected light in different directions, thereby achieving a variety of angles of reflected light, that is, realizing a dazzling visual effect when lit.

[0015] Furthermore, the end face of the light-incident surface is located on the plane formed by the X and Y directions, and the light-incident surface is located at the bottom of the thick-walled component; thus, the LED light can be set at the bottom of the thick-walled component, at any position on the light-incident surface. Through integrated setting, the space occupied by the vehicle light is reduced to meet the placement requirements of small spaces.

[0016] Furthermore, a collimation structure is provided on the outer side of the light-incident surface; thereby, efficient light energy transmission is achieved and the lighting effect is improved.

[0017] Furthermore, the thick-walled component also includes a second reflective surface, which is positioned opposite to the first reflective surface and located below the first reflective surface. The planes formed by the X and Y directions of the end face of the second reflective surface intersect at an obtuse angle. The end face of the light-incident surface intersects the planes formed by the X and Y directions at an obtuse angle. One end of the light-incident surface is connected to the first reflective surface, and the other end of the light-incident surface is connected to the second reflective surface. The inner side of the second reflective surface undergoes total internal reflection. Thus, if the incident light is parallel to the X direction, after passing through the incident surface, the second reflective surface deflects the light back to the first reflective surface, thereby achieving a dazzling visual effect. The use of a double reflective surface instead of the traditional LED direct-lighting surface with a dazzling effect pattern ensures the same effect while occupying less space, making it suitable for flat automotive headlight fixtures.

[0018] The beneficial effect of this utility model is that the optical structure of this utility model that can achieve a bright and dazzling visual effect is provided with a reflective surface with a special pattern. When light is randomly irradiated and shines on the reflective surface at any angle, the reflection angle is different at the special pattern, thereby achieving a bright and dazzling visual effect.

[0019] The optical structure of this utility model that can achieve a dazzling visual effect is provided with a reflective surface. The light source is set at any position on the light-incident surface, which reduces the restriction on the LED position arrangement, reduces the space occupied by the car light, and thus improves the plasticity of the car light installation space to meet the placement requirements of small spaces.

[0020] The optical structure of this utility model has a second reflective surface and a first reflective surface. The use of double reflective surfaces replaces the traditional LED direct light-emitting surface with a dazzling effect pattern. While ensuring the same effect, it occupies less space and is suitable for flat automotive headlight fixtures. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] Example 1: Refer to Figure 1 , Figure 2 , Figure 5 An optical structure capable of achieving a dazzling visual effect includes a thick-walled component. The width direction of the thick-walled component is defined as the X-direction, and the height direction as the Z-direction. The length direction of the thick-walled component is then defined as the Y-direction (see reference). Figure 2 );

[0031] The thick-walled component includes a light-emitting surface 11, a light-incident surface 12, and at least one reflective surface 13. The reflective surface 13 is located at one end of the thick-walled component, the light-incident surface 12 is located on one side of the reflective surface 13, and the light-emitting surface 11 is located at the other end of the thick-walled component. The light-emitting surface 11 is located on a plane formed by the Z and Y directions, and the outer side of the light-emitting surface 11 is a smooth surface or has a pattern or texture. The end face of the light-incident surface 12 is located on a plane formed by the X and Y directions, and the light-incident surface 12 is located at the bottom of the thick-walled component. Thus, the LED light can be set at the bottom of the thick-walled component, at any position on the light-incident surface 12. Through integrated installation, the space occupied by the vehicle light is reduced to meet the placement requirements of small spaces.

[0032] The overall shape of reflective surface 13 is planar, parabolic, hyperboloid, or freeform. The end face of reflective surface 13 intersects the plane formed by the X and Y directions at an obtuse angle. Reflective surface 13 is angled upwards. Reflective surface 13 is vacuum-coated. Multiple non-directional protrusions are provided on the inner side of reflective surface 13 (see reference). Figure 1 The protruding part in the middle section is irregularly arranged; the inner side of the reflective surface 13 is provided with a special pattern 131, which randomly reflects the light rays incident on it.

[0033] Reference Figure 5The special pattern 131 includes multiple irregular polygons that are randomly distributed without overlapping and have varying sizes. Multiple irregular polygons are connected to form a special reflective part, so that light shines randomly onto the reflective surface 13 at any angle. The protrusions on the reflective surface 13 and the special pattern 131 cause the incident light to be reflected in different directions, thus achieving a variety of angles for the reflected light and achieving a dazzling visual effect. By setting the reflective surface 13, the restrictions on the placement of LEDs are reduced, thereby improving the flexibility of the vehicle headlight installation space.

[0034] Example 2: Refer to Figure 2 , Figure 3 Based on Embodiment 1, the following addition is made: a collimation structure is provided on the outer side of the light incident surface 12. The collimation structure adopts a condenser 15. The LED lamp is located at the end of the condenser 15 away from the light incident surface 12 and corresponds one-to-one with the condenser 15. Thus, efficient light energy transmission is achieved through the condenser 15, and the lighting effect is improved.

[0035] Example 3:

[0036] Reference Figure 4 The difference from Embodiment 1 is that the thick-walled component also includes a second reflective surface 14, which is disposed opposite to the first reflective surface 13 and is located below the first reflective surface 13. The planes formed by the X and Y directions of the end face of the second reflective surface 14 intersect, and the angle of intersection is an obtuse angle.

[0037] The end face of the light-incident surface 12 intersects the plane formed by the X and Y directions, and the angle of intersection is obtuse. One end of the light-incident surface 12 is connected to the first reflective surface 13, and the other end of the light-incident surface 12 is connected to the second reflective surface 14. The inner side of the second reflective surface 14 is totally internally reflected. Thus, if the incident light is parallel to the X direction, after passing through the incident surface, the second reflective surface 14 will turn the light to the first reflective surface 13, thereby achieving a dazzling visual effect. The use of double reflective surfaces instead of the traditional LED direct light plus the setting of dazzling effect patterns at the light-emitting surface 11 ensures the same effect while occupying less space, making it suitable for flat automotive headlight fixtures.

[0038] Example 4: Refer to Figure 6 The difference from Embodiment 1 is that the special pattern 131 includes multiple star-shaped patterns, which are arranged randomly. The center points of the multiple star-shaped patterns do not overlap, and the star-shaped patterns are interspersed with adjacent star-shaped patterns. The center point of some star-shaped patterns coincides with the protrusion. As a result, the multiple star-shaped patterns have different distribution densities on the reflective surface 13. The star-shaped patterns intersect with adjacent star-shaped patterns to form an irregular closed pattern. When light shines on the special reflective part at any angle, the angle of reflection is also different, thereby achieving a dazzling visual effect of illumination.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
