Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an ambient lighting system for illuminating three-dimensional shapes. Background Technology

[0002] As the configuration of new energy vehicles continues to upgrade, people have put forward more and more requirements for the lighting effect of car ambient lighting, and more three-dimensional, gradient and breathing effects are being added to the design.

[0003] For example, CN222278338U discloses a diamond-patterned light guide and ambient light. The diamond-patterned light guide includes a long strip-shaped light guide body, which includes a light-inlet strip and a light-outlet strip arranged side by side along its width direction. The two sides of the light-outlet strip in the thickness direction are composed of multiple small planes, and the included angle between adjacent small planes is greater than 0° and less than 180°. Each end of the car ambient light guide is provided with an LED, resulting in a single light effect. It can only change color and adjust brightness, without any three-dimensionality, and cannot achieve complex three-dimensional effects such as flowing water, resulting in insufficient sense of technology and high-end feel.

[0004] While existing ambient lights have a three-dimensional effect, they can only be viewed from a specific angle and cannot provide a three-dimensional effect from multiple angles, thus affecting the user experience. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes an ambient lighting optical system for illuminating three-dimensional shapes.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] An ambient lighting optical system for illuminating three-dimensional shapes includes a light guide plate and a shape cover placed on the light guide plate;

[0008] The top of the shaped cover has several concave shaped grooves, and radial shaped lines radiate outward from the center of the shaped grooves. The joint of the shaped grooves forms a raised shaped line, and several light guide pits are formed on the light guide plate. The light guide pits are arranged opposite to the radial shaped lines and the raised shaped lines so that the brightness of the radial shaped lines gradually darkens along the scattering direction.

[0009] Preferably, the brightness of the raised molding line gradually darkens from the midpoint toward both sides. Through the above improvements, the effect of the molding groove is further enhanced.

[0010] Preferably, the density and / or size of the light guide pits gradually decrease along the scattering direction of the radial sculpting line. Through the above improvements, as the radial sculpting line extends outward, the distribution density and size of the light guide pits decrease simultaneously, ensuring a more natural and uniform brightness attenuation gradient.

[0011] Preferably, the size and density of the light guide pit decrease as the distance between the radial and raised molding lines and the light guide plate increases. Through the above improvements, the size and density of the light guide pit decrease as the distance between the radial and raised molding lines and the light guide plate increases, in order to compensate for the loss during light transmission.

[0012] Preferably, the light guide pit is arc-shaped. Through the above improvements, the light transmission effect is optimized, and dark areas and bright spots can be avoided.

[0013] Preferably, the light guide plate has raised ribs, and the raised ribs are arranged opposite to the raised shaping lines. Through the above improvements, the brightness of the raised shaping lines is centered, so as to better create the three-dimensional effect of the shaping cover.

[0014] Preferably, the height and width of the raised rib shape gradually decrease from the center along both ends, thereby increasing the light emission angle of this area of ​​the light guide plate through the above improvements.

[0015] Preferably, the surface of the raised rib is provided with a frosted texture. Through the above improvements, the brightness of the raised rib is not lower than that of the radiating rib when viewed at an angle, and not higher than that of the convergence point of the rib when viewed from the front.

[0016] Preferably, the light guide plate and the light guide plate are provided with mounting clips. Through the above improvements, the mounting clips cooperate with the base to achieve quick installation of the light guide plate and the light guide plate.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] The top of the decorative cover features several concave grooves, with radial decorative lines radiating outwards from the center of each groove. The joints of the grooves form raised decorative lines. A light guide plate has several light guide pits, positioned opposite the radial and raised decorative lines. The PCB light board uses these pits to influence the radial and raised decorative lines, causing the brightness of the radial lines to gradually dim along the scattering direction. This increases the brightness variation of the radial and raised decorative lines, enhancing the sense of light and shadow and improving the three-dimensional effect of the decorative cover. Users can experience the three-dimensional effect of the ambient light from multiple angles, thus enhancing the visual experience. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0027] like Figure 1-5 As shown, an ambient lighting optical system for illuminating a three-dimensional shape includes a light guide plate 1 and a shape cover 2 placed on the light guide plate 1.

[0028] Specifically, the top of the decorative cover 2 has several concave decorative grooves 3, and radial decorative lines 4 radiate outward from the center of the decorative grooves 3. The joint of the decorative grooves 3 forms raised decorative lines 5, and several light guide pits 6 are formed on the light guide plate 1. The light guide pits 6 are arranged opposite to the radial decorative lines 4 and the raised decorative lines 5. The PCB light board acts on the radial decorative lines 4 and the raised decorative lines 5 through the light guide pits 6 on the light guide plate 1, so that the brightness of the radial decorative lines 4 gradually darkens along the scattering direction, thereby increasing the brightness variation of the radial decorative lines 4 and the raised decorative lines 5, increasing the sense of light and shadow layering, and enhancing the three-dimensional effect of the decorative cover 2. This allows users to experience the three-dimensional effect of the ambient light from multiple angles, thereby enhancing the visual effect for users.

[0029] As a preferred design, the brightness of the raised sculpted line 5 gradually dims from the center point toward both sides, further enhancing the sense of light and shadow.

[0030] like Figure 1-5 As shown in the further explanation of the implementation of the light guide pit 6, the density and / or size of the light guide pit 6 gradually decreases along the scattering direction of the radial shaping line 4. As the radial shaping line 4 extends outward, the distribution density and size of the light guide pit 6 decrease simultaneously, ensuring a more natural and uniform brightness attenuation gradient.

[0031] Furthermore, the size and density of the light guide pit 6 decrease as the distance between the radial shaping line 4 and the raised shaping line 5 and the light guide plate 1 increases, in order to compensate for the loss during the light transmission process, thereby improving the three-dimensional effect of the shaping cover 2.

[0032] Preferably, the light guide pit 6 is arc-shaped to optimize the light transmission effect and avoid dark areas and bright spots, thereby further improving the visual effect.

[0033] like Figure 1-5 As shown, in a further explanation of the embodiment of the light guide plate 1, the light guide plate 1 is provided with raised ribs 7, and the raised ribs 7 are arranged opposite to the raised shaping line 5 so that the brightness of the raised shaping line 5 is centered, so as to better create the three-dimensional effect of the shaping cover 2.

[0034] The height and width of the raised rib 7 gradually decrease from the center to both ends. The surface of the raised rib 7 is provided with a frosted texture to increase the light output angle of the light guide plate 1 in this area. At the same time, when the raised rib 5 is viewed at an angle, the brightness is not lower than that of the radiating rib, and when viewed from the front, the brightness is not higher than that of the convergence point of the rib.

[0035] like Figure 1 As shown, as a further explanation of the installation of the light guide plate 1, mounting clips 8 are formed on the light guide plate 1. The entire ambient lighting optical system also includes a PCB light board, an outer lamp cover, and a base. The PCB board is installed on the base with screws, and the light guide plate 1, the shaped cover 2, and the outer lamp cover are fastened and fixed on the base by the mounting clips 8, so as to realize the quick installation of the entire ambient lighting optical system.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
