Description

Technical Field

[0001] This invention relates to the field of ambient lighting, and more specifically to an ambient lighting assembly with a starry sky effect. Background Technology

[0002] With the continuous development of automotive interiors, car owners are increasingly inclined to equip their vehicles with a large number of interior and ambient lighting fixtures to personalize their cars. Ambient lighting can be installed in various locations, including the steering wheel, center console, footwell lights, cup holders, roof, welcome lights, door sills, trunk, and headlights. Currently, there are two types of ambient ceiling lights on the market that can achieve a starry sky effect: The first type uses optical fibers. This type of ambient lighting works by manually fixing the ends of numerous optical fibers to the vehicle's roof, allowing the light emitted from these fibers to illuminate the roof. The advantages of this type of ambient lighting are its starry sky effect, with flexible and changeable star patterns. Furthermore, because the optical fibers can be independently controlled, a shooting star effect can be created (optical fibers along a straight line sequentially light up and turn off). However, its disadvantages are also obvious: the installation process is time-consuming, labor-intensive, and requires manual installation, resulting in high costs. Currently, it is only used in high-end vehicles.

[0003] The second type uses a single piece of acrylic light guide plate. This type of ambient ceiling light works by setting several reflective points arranged according to a design on the reflective surface of the light guide plate. Near-light rays are emitted from the side of the light guide plate, propagating within it and reflecting off the reflective points before exiting onto the ceiling. The advantages of this type of ambient ceiling light are low cost and a starry sky effect. However, its disadvantage is that the effect is monotonous; all the light points can only be lit and dimmed simultaneously, and it cannot achieve the shooting star effect of the first type of ambient ceiling light. Summary of the Invention

[0004] To avoid the shortcomings of the prior art, the present invention provides an ambient light assembly with a starry sky effect, which is relatively low in cost and can achieve the visual effects of twinkling stars and shooting stars.

[0005] This invention proposes an ambient lighting assembly with a starry sky effect, comprising a housing and a light guide plate, a first circuit board, a second circuit board, and an isolation plate fixedly mounted to the housing. The light guide plate includes a light-inlet surface, a reflective surface, and a light-outlet surface. The reflective surface of the light guide plate has several reflective points that can reflect light. The first circuit board is disposed on the light-inlet surface side of the light guide plate. The first circuit board includes a microcontroller and several first LED light modules connected to the microcontroller. The light emitted by the first LED light modules enters from the light-inlet surface, is reflected by the reflective points, and exits from the light-outlet surface. The light guide plate has several through holes penetrating the reflective surface and the light-outlet surface. The isolation plate is located on the reflective surface of the light guide plate. The lower end of the isolation plate has several light-blocking pillars that are installed in a one-to-one correspondence with the through holes. The light-blocking pillars have light-emitting holes that penetrate the isolation plate. The isolation plate can isolate light from entering and exiting between the light guide plate and the light-emitting holes. The second circuit board is located on the isolation plate, and the circuit of the second circuit board is connected to the first circuit board. The second circuit board includes several second LED modules connected to the microcontroller. The positions of the second LED modules correspond to the light-emitting holes, and the light emitted by the second LED modules is emitted from the light-emitting holes. The microcontroller can independently control the brightness and color of each second LED module.

[0006] Furthermore, all or some of the through holes in the light guide plate are arranged in a straight line and spaced at a preset distance.

[0007] Furthermore, it also includes an optical fiber lamp module connected to a microcontroller; the optical fiber lamp module includes a light source and several optical fibers with their ends fixed at the light source; the light guide plate is provided with several fixing holes that penetrate the reflective surface and the light-emitting surface, and the fixing holes are used to fix the ends of the optical fibers; the microcontroller can independently control the brightness and color of the optical fiber lamp module.

[0008] Furthermore, the side of the end of the optical fiber has a light-shielding layer, the length of which is greater than the thickness of the light guide plate.

[0009] Furthermore, a transparent plug is fixed inside the light outlet, which can seal the light outlet.

[0010] The present invention also proposes a vehicle comprising an ambient lighting assembly with a starry sky effect as described in any of the above claims.

[0011] The advantages of this invention are that, compared with the all-fiber optic starry sky roof solution in the prior art, it is easier to install, lower in cost, and easier to popularize in low- and mid-range vehicles; compared with the pure acrylic light guide plate starry sky roof solution, it also has the effect of shooting stars and twinkling stars, which provides a better user experience.

[0014] Figure 3 This is a cross-sectional schematic diagram of the ambient lighting assembly in the embodiment. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Example, see attached document Figure 1-3 An ambient light assembly with a starry sky effect includes a housing 1 and a light guide plate 5, a first circuit board 6, a second circuit board 2, and an isolation plate 3 fixedly mounted to the housing 1. The light guide plate 5 includes a light-inlet surface, a reflective surface, and a light-outlet surface. The reflective surface of the light guide plate 5 has a plurality of reflective dots 51 that can reflect light. In this embodiment, the reflective dots 51 are all laser dots formed by laser etching on the reflective surface of the light guide plate 5 using a laser dotting machine. The first circuit board 6 is located on the light-inlet side of the light guide plate 5. The first circuit board 6 includes a microcontroller and a plurality of first LED light modules connected to the microcontroller. The light sources of the first LED light modules are attached to the light-inlet surface of the light guide plate 5 and emit light... Light enters from the light-inlet surface, is reflected by the reflector 51, and exits from the light-outlet surface. The light guide plate 5 has several through holes 52 that penetrate the reflector and the light-outlet surface. All or part of the through holes 52 are arranged in a straight line and spaced at a preset distance. The isolation plate 3 is located on the reflector surface of the light guide plate 5. The lower end face of the isolation plate 3 has several light-blocking columns 31 that are installed in a corresponding manner to the through holes 52. The light-blocking columns 31 have light-outlet holes 32 that penetrate the isolation plate 3. The isolation plate 3 can isolate light from entering and exiting between the light guide plate 5 and the light-outlet holes 32. A transparent plug 4 is also fixed inside the light-outlet hole 32. The transparent plug 4 can seal the light-outlet hole 32 to prevent dust and make the light softer and more uniform. The second circuit board 2 is mounted on the isolation plate 3. The circuit of the second circuit board 2 is connected to the first circuit board 6 via ribbon cables or connectors, so that the microcontroller can also control the components of the second circuit board 2. The second circuit board 2 includes several second LED light modules 21 connected to the microcontroller. The positions of the second LED light modules 21 and the light emission holes 32 are matched and correspond. The light emitted by the second LED light modules 21 is emitted from the light emission holes 32. The microcontroller can independently control the brightness and color of each second LED light module 21.

[0017] The final visual effects presented by the ambient lighting assembly in this embodiment include starry sky effect, shooting star effect, and twinkling starlight effect, wherein: The starry sky effect is achieved through the light guide plate 5. Light emitted from a certain number of first LED light modules enters from the side of the light guide plate 5, and when it shines on the reflective points 51, it undergoes diffuse reflection and refraction, and finally exits from the light-emitting surface. Each reflective point 51 is equivalent to a luminous star. The size, number, and position of the starlight depend on the size, number, and position of the reflective points 51 that are pre-set on the reflective surface of the light guide plate 5.

[0018] The meteor effect is achieved by the second LED light modules 21 arranged in a straight line. Since the second LED light modules 21 can be independently controlled by the microcontroller, when the second LED light modules 21 in a straight line are lit and turned off or lit and then gradually dimmed, the visual effect presented to the user is like the effect of a meteor streaking across the sky. Due to the presence of the isolation plate 3, the light in the light guide plate 5 will not enter the light outlet 32 ​​and affect the light emitted by the second LED light modules 21.

[0019] The twinkling starlight effect is achieved through the second LED light module 21. Unlike the light emitted from the light guide plate 5, which emits multiple light points that can only be lit or turned off simultaneously, the second LED light module 21 can be independently controlled by a microcontroller. Therefore, the brightness of multiple second LED light modules 21 can be controlled by a program to achieve the twinkling starlight effect. However, this method also has significant drawbacks: to achieve a realistic effect, the twinkling starlight should be distributed throughout the entire starry sky, rather than being limited to a certain area. This would require the second circuit board 2 to be made very large. Currently, the area of ​​a car roof is approximately 1.5 to 2 square meters. While it's cost-effective to make the light guide plate 5 that large, manufacturing the second circuit board 2 to be that large would be difficult and impractical, and even if it were possible, the cost would be very high.

[0020] To achieve a better starlight effect, this embodiment also includes an optical fiber lamp module connected to a microcontroller. The microcontroller can independently control the brightness and color of the optical fiber lamp module. The optical fiber lamp module includes a light source and several optical fibers with their ends fixed at the light source. The light guide plate 5 has several fixing holes for fixing the ends of the optical fibers, and these fixing holes also penetrate the light guide plate 5. The side of the end of the optical fiber has a light-shielding layer, the length of which is greater than the thickness of the light guide plate 5. The light-shielding layer can isolate light from entering and exiting between the light guide plate 5 and the fixing holes. The advantages of using an optical fiber lamp module are that the length of the optical fiber can be adjusted arbitrarily, so it is convenient to fix the optical fiber at any position on the light guide plate 5; secondly, the twinkling starlight is only an embellishment, and the actual number is not large, so it will not increase the cost too much.

[0021] Compared to the all-fiber optic starry sky roof solution in the background technology, the ambient lighting assembly in this embodiment is easier to install, lower in cost, and easier to popularize in low- and mid-range vehicles; compared to the pure acrylic light guide plate starry sky roof solution, it also has the effect of shooting stars and twinkling stars, providing a better user experience.

[0022] It should be noted that, in addition to being used on vehicle roofs, the ambient lighting assembly of this embodiment can also be used in other scenarios such as billboards, interior decorations, and ceiling installations.
