Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive interior technology, and in particular to an ambient light with a three-dimensional visual effect. Background Technology
[0002] With the development of the automotive industry, automotive interior design increasingly emphasizes driving experience and emotional expression, making ambient lighting an important feature for enhancing vehicle quality and personalization. Currently, most ambient lights on the market use LED light sources combined with simple light guides or diffusion structures to achieve basic single-color or gradient lighting effects, all of which are planar lighting effects. There are currently no reports on three-dimensional ambient lighting for car interiors. However, three-dimensional ambient lighting can increase the sense of depth and sophistication of the ambient lighting, thus requiring the development of a new type of ambient light. Summary of the Invention
[0003] The purpose of this invention is to provide an ambient light with a three-dimensional visual effect, thereby enhancing the sense of depth and visual appeal of indoor ambient lighting.
[0004] The technical solution adopted by this invention to solve its technical problem is: an ambient light with a three-dimensional visual effect, having:
[0005] Backlight provides the necessary light source for the light guide;
[0006] The first light guide is arranged along a predetermined path to directly receive light emitted from the backlight.
[0007] A single-sided lens is located above the first light guide. The single-sided lens has a light-transmitting area located directly above the first light guide. Light passes through the first light guide and then through the light-transmitting area to enter the top of the single-sided lens.
[0008] The cover, located above the one-way lens, forms a reflective space with the one-way lens. The cover has both a certain degree of transparency and a certain degree of reflectivity. Light passes through the light-transmitting area of the one-way lens and shines onto the cover. Some of the light passes through the cover and shines out, while the other part is reflected onto the surface of the one-way lens and then reflected back onto the cover. Under the action of the cover, some of the light continues to pass through the cover and shine out, while the other part is reflected back onto the one-way lens. This process continues, thus forming a set of bright areas below the cover with light intensity decreasing and shapes matching the light-transmitting area, thereby creating a stereoscopic visual effect.
[0009] To enhance the three-dimensional effect, a second light guide is provided on the outside of the first light guide. The top and sides of the second light guide are provided with opaque coverings, and light shines through the lower surface of the second light guide. A reflective surface is provided below the second light guide.
[0010] Furthermore, the cover has a curved surface structure.
[0011] Preferably, the cover includes a semi-transparent cover plate on the upper surface and a second PVD reflective film located below the semi-transparent cover plate; the upper surface of the single-sided lens is provided with a first PVD reflective film.
[0012] To enhance the three-dimensional effect, the shape of the light-transmitting area is either a continuous ring or a discontinuous ring, and the brightness of the brightest area is not less than 10 nt.
[0013] Preferably, the first light guide is a closed annular structure, and the cross-section of the first light guide is circular.
[0014] Furthermore, the first light guide has at least two pins, and a backlight is provided below each pin.
[0015] Preferably, the width of the light-transmitting area is adapted to the width of the first light guide.
[0016] The beneficial effects of this invention: Through the effective combination of light guide, single-sided lens and cover, light is reflected and refracted through multiple channels, making the light more layered and thus forming a three-dimensional effect, improving the grade of the in-vehicle ambient lighting.
[0017] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0025] Examples, such as Figures 1 to 3 As shown, an ambient light with a three-dimensional visual effect has the following features:
[0026] Backlight 1 provides the necessary light source for the light guide;
[0027] The first light guide 2 is arranged along a set path to directly receive the light emitted by the backlight 1;
[0028] A single-sided lens 3 is located above the first light guide 2. The single-sided lens 3 is composed of a light-transmitting sheet 31 and a first PVD reflective film 32 located above the light-transmitting sheet 31. A light-transmitting area 33 is provided on the first PVD reflective film 32 of the single-sided lens 3. The light-transmitting area 33 is located directly above the first light guide 2. Light passes through the first light guide 2 and then through the light-transmitting area 33 to enter the top of the single-sided lens 3.
[0029] The cover 4 is located above the single-sided lens 3, forming a reflection space 5 between them. The cover 4 has both a certain degree of transparency and a certain degree of reflectivity. Light passes through the light-transmitting area 31 of the single-sided lens 3 and shines onto the cover 4. Part of the light passes through the cover 4 and shines out, while the other part is reflected onto the surface of the single-sided lens 3 and then reflected back onto the cover 4. Under the action of the cover 4, some light continues to pass through the cover 4 and shine out, while the other part is reflected back onto the single-sided lens 3. This process continues, thus forming a set of bright areas 44 below the cover 4, with light intensity decreasing and shapes matching the light-transmitting area 33, thereby creating a stereoscopic visual effect.
[0030] A second light guide 6 is provided on the outer side of the first light guide 2. An opaque cover 7 is provided on the top and side of the second light guide 6. Light passes through the lower surface of the second light guide 6. A reflective surface 8 is provided below the second light guide 6, thereby forming a reflective halo in visual effect and improving the overall three-dimensional effect of the ambient light.
[0031] To enhance the three-dimensional effect, the cover 4 has a curved structure. The cover 4 includes a translucent cover plate 41 on the upper surface and a second PVD reflective film 42 located below the translucent cover plate 41; the light-transmitting area 33 is in a continuous annular shape, such as... Figure 4 As shown, light rays emitted from the light-transmitting area 33 undergo continuous reflections, thus forming an image as shown. Figure 5 The multi-ringed bright area 44 is shown. To improve the three-dimensional effect, the brightness of the brightest bright area 44 (i.e., the bright area located directly above the light-transmitting area 33) is not less than 10nt.
[0032] As another implementation, the shape of the light-transmitting area 33 can also be a discontinuous ring, such as... Figure 6 The dotted light-transmitting structure shown creates a shape like... Figure 7The multi-ringed dotted bright areas 44 shown create a radial dotted stereoscopic visual effect.
[0033] In addition, the light-transmitting area 33 can also adopt various shapes and structures such as straight lines and characters, which will not be exemplified here.
[0034] To further enhance the visual three-dimensionality, the first light guide 2 is a closed ring structure with a circular cross-section.
[0035] To improve the uniformity and intensity of the light source, the first light guide 2 is provided with at least two pins 21, and a backlight 1 is provided below each pin 21.
[0036] The following example is a car interior dome light: The car interior dome light includes a base 10, a circuit board 20 disposed in the base 10, a waterproof rubber 30 disposed on the circuit board 20, and a housing 40 mounted on the base 10. The housing 40 is provided with a stepped surface 401, and a first light guide 2 is placed on the stepped surface 401. The two pins 21 of the first light guide 2 enter the circuit board 20 through the through hole of the housing 40, so that the ends of the pins 21 are located above the backlight 1 of the circuit board 20.
[0037] A single-sided lens 3 is disposed above the first light guide 2, and a second light guide 6 is disposed outside the first light guide 2. A cover 4 is disposed above the single-sided lens 3, and the cover 4 has an integrally injection-molded connecting part 43. The connecting part 43 fixes the single-sided lens 3 and forms a sealed reflective space 5 between the single-sided lens 3 and the cover 4. An opaque cover 7 is integrally injection-molded on the second light guide 6, and the cover 7 is snapped and fixed to the connecting part 43. This structure encloses the first light guide 2 in the middle, so that light can only be emitted through the cover 4 above the first light guide 2 and the second light guide 6, forming visible light. Under the action of the cover 7, light can only be emitted from below the second light guide 6. A reflective surface 8 is disposed on the base 10 below the second light guide 6. Light passes through the second light guide 6 and shines on the reflective surface 8, and is reflected out, thus forming a reflective halo in visual effect.
[0038] The single-sided lens 3 is composed of a light-transmitting sheet 31 and a first PVD reflective film 32 located above the light-transmitting sheet 31. A light-transmitting area 33 is laser-engraved on the first PVD reflective film 32. The light-transmitting area 33 is located directly above the first light guide 2 and its width is adapted to the diameter of the first light guide 2. After the light from the backlight 1 passes through the first light guide 2, it can be directly projected onto the faceplate 4 through the light-transmitting area 33, thereby forming a high-brightness aperture. In order to achieve a stereoscopic visual effect, the brightness of the brightest aperture is not less than 10 nt.
[0039] The cover 4 has a curved structure and includes a semi-transparent cover plate 41 on the upper surface and a second PVD reflective film 42 below the semi-transparent cover plate 41. Under the action of the semi-transparent cover plate 41, the light transmittance of the cover 4 is 68% to 70%. Through the cooperation of the cover 4 and the single-sided lens 3, light can be reflected in the reflection space 5, while some light can be directly emitted from the refraction position of the cover 4. This makes the two ends of the refraction position brighter than the surrounding area. As the light is gradually lost during the refraction process, a set of gradually decreasing brightness rings (i.e., arc-shaped bright areas 44) are formed on the cover, creating a three-dimensional effect.
[0040] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
