[0030] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] An optical component with a 3D depth effect, comprising: a thick-walled member 1 and a light emitter 9, the thick-walled member 1 having a light incident surface 2 and a light emitting surface 3, a semi-transparent and semi-reflective film 4 being arranged on the light emitting surface 3, the light incident surface 2 comprising a first area 5 and a second area 6, the first area 5 being light-transmissive, and a reflective film 7 being arranged on the second area 6; the light emitter 9 being arranged on the outer side of the light incident surface 2 and facing the first area 5, the light emitted by the light emitter 9 all passes through the first area 5 and is projected onto the semi-transparent and semi-reflective film, a part of the light passes through the semi-transparent and semi-reflective film to be emitted, and the other part passes through the semi-transparent and semi-reflective film to be reflected onto the reflective film 7, and then passes through the reflective film 7 to be reflected onto the semi-transparent and semi-reflective film.

[0032] It should be noted that the semi-transparent and semi-reflective film 4 is plated on the light-emitting surface 3, and the semi-transparent and semi-reflective film 4 needs to completely cover the light-emitting surface 3, and the reflective film 7 is plated on the second area 6. By covering the light-emitting surface 3 of a thick-walled component 1 with the semi-transparent and semi-reflective film 4 and arranging the reflective film 7 on the second area 6 of the light-incident surface 2, the image formed by the light passing through the semi-transparent and semi-reflective film 4 and the reflective film 7 has a 3D depth effect.

[0033] The first area 5 is a smooth surface or is provided with a pattern or is frosted.

[0034] It should be noted that the first area 5 must still have light transmission ability after being provided with a pattern or frosted. Setting a pattern or frosting the first area 5 can change the way light propagates, which helps to disperse the light more evenly throughout the first area 5, reduce reflection and glare, and increase visual effects and aesthetics.

[0035] The luminous body 9 is a light guide bar or a light source.

[0036] It should be noted that when the light-emitting body 9 is a light-guiding strip, light can be transmitted uniformly throughout the first region 5 .

[0037] The thick-walled part 1 is arranged in a square, circular or irregular shape.

[0038] It should be noted that the thick-walled member 1 can be designed according to the specific structural shape of the optical device, automobile glass, architectural glass, car lamp or rearview mirror.

[0039] The light emitting end of the light emitting body 9 is arranged facing the first area 5 .

[0040] It should be noted that the location and arrangement shape of the light-emitting body 9 can be changed according to the actual shape requirements of the vehicle lamp.

[0041] The first region 5 includes one or more first discrete surfaces, and the second region 6 includes one or more second discrete surfaces. The one or more first discrete surfaces are arranged around the second discrete surfaces and match the position of the light emitter 9 .

[0042] It should be noted that: the first area 5 can be a complete surface or composed of multiple first discrete surfaces, the second area 6 can be a complete surface or composed of multiple second discrete surfaces, the setting position and arrangement shape of the first discrete surface must correspond to the position of the light-emitting body 9 to ensure that the light-emitting body 9 is located directly in front of the first area 5. The design of the first area 5 surrounding the second area 6 makes the image formed after the light is emitted through the semi-transparent and semi-reflective film 4 to be closed, thereby increasing the visual effect and 3D depth effect.

[0043] The reflective film 7 is arranged in a plane or a curved surface.

[0044] A vehicle lamp comprises any one of the above optical components with 3D depth effect.

[0045] It should be noted that the application of this optical component with 3D depth effect in the automotive field not only meets the lighting and signal functions of the headlights, but also enhances the three-dimensional sense and visual effects.

[0046] See also Figure 2 As shown, the specific working principle is as follows:

[0047] The light emitted by the luminous body 9 is projected onto the semi-transparent and semi-reflective film 4 through the first area 5. Each time the light passes through the semi-transparent and semi-reflective film 4, it is divided into two parts. One part passes through the semi-transparent and semi-reflective film 4 and directly emits to form image A, and the other part passes through the semi-transparent and semi-reflective film and is reflected onto the reflective film 7, and then passes through the reflective film 7 and is reflected onto the semi-transparent and semi-reflective film. The light reflected onto the semi-transparent and semi-reflective film is divided into two parts again. One part passes through the semi-transparent and semi-reflective film 4 and directly emits to form image B, and the other part passes through the semi-transparent and semi-reflective film and is reflected onto the reflective film 7, and then passes through the reflective film 7 and is reflected onto the semi-transparent and semi-reflective film. The light reflected onto the semi-transparent and semi-reflective film is divided into two parts again. One part passes through the semi-transparent and semi-reflective film 4 and directly emits to form image C. By analogy, the inner contour of each image is larger than the outer contour of the image formed after being reflected once by the reflective film 7 adjacent to it. A plurality of images are arranged in sequence, that is, see Figure 3 As shown, images A, B and C are nested in sequence, the inner contour of image A is larger than the outer contour of image B, the inner contour of image B is larger than the outer contour of image C, and so on, gradually forming an image with a 3D depth effect.

[0048] In summary, the beneficial effects of the utility model are:

[0049] By covering the light emitting surface 3 of a thick-walled component 1 with a semi-transparent and semi-reflective film 4 and arranging a reflective film 7 on a partial area of ​​the light incident surface 2, utilizing the dual characteristics of the semi-transparent and semi-reflective film 4 that can both transmit light and reflect light and the reflective characteristics of the reflective film 7, the image formed after the light passes through the semi-transparent and semi-reflective film 4 and the reflective film 7 has a 3D depth effect. The 3D depth effect can be achieved by using only one thick-walled component 1 in combination with the semi-transparent and semi-reflective film 4 and the reflective film 7, thereby reducing the number of parts used and the difficulty of assembly.
