[0032] The specific embodiments of the present application have been shown through the above-mentioned drawings, and will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0034] First of all, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can adjust them as needed in order to adapt to specific application occasions.

[0035] Secondly, it needs to be explained that in the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be wired connection, but also wireless connection; It can also be the internal communication of two components. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] With the continuous development of the automotive industry, the starry sky effect has become an innovative element in vehicle design. This design not only enhances the aesthetic appearance of the vehicle, but also perfectly combines modern technology and art. This design not only adds unique charm to the vehicle visually, but also provides practical benefits in terms of functionality. Through careful design of light distribution and intensity adjustment, the starry sky effect can significantly improve the lighting performance of the vehicle, especially at night, providing drivers with a clearer view, thereby improving driving safety. This design is usually achieved by arranging a large number of LED light sources in the vehicle lights. LED light sources are the ideal choice for simulating starry sky effects due to their high efficiency, durability, and flexible control characteristics.

[0037] In related technologies, the implementation of the starry sky effect mainly relies on the precise control of the electronic control unit. The electronic control unit manages the lighting sequence or regional on-off of the LED light sources through programming to simulate the flickering of the starry sky. The use of an electronic control unit to manage LED light sources makes the starry sky effect observed by users from any angle the same, which reduces the user's experience.

[0038] To solve the above problems, the inventors consider designing a lamp for generating starry sky effect using a multi-angle reflector, so that the starry sky effect can exhibit diversity with changes in the observation area. In specific implementation, the lamp for generating starry sky effect can include LED light sources, a multi-angle reflector, and a light filter plate, the light filter plate is provided with a plurality of through holes, the multi-angle reflector is used to reflect the light emitted by the LED light sources at multiple angles, and the reflected light realizes the starry sky effect through the plurality of through holes on the light filter plate. Based on this, the present application proposes a lamp for generating starry sky effect, which aims to solve the problem of single starry sky effect and lack of change through the innovative application of multi-angle reflector, to improve user experience. Further, through this innovative lamp design, the starry sky effect of the vehicle will no longer be static and single, but can change with the user's viewing angle and environmental changes, providing a more rich and personalized visual experience.

[0039] Figure 1 The structure diagram of the lamp for generating starry sky effect according to the first embodiment of the present application is provided. Please see Figure 1 The lamp 10 can include LED light sources 11, a multi-angle reflector 12, and a light filter plate 13.

[0040] The light filter plate 13 is provided with a plurality of through holes 131.

[0041] The multi-angle reflector 12 is used for multi-angle reflection of light emitted by the LED light source 11, and the light reflected by the multi-angle reflector 12 realizes the starry sky effect through the plurality of through holes 131 on the light filter plate 13.

[0042] Optionally, the shape of the through hole 131 includes at least one of the following: a circle, an ellipse, a star, a triangle, a square, a rectangle, a diamond, a trapezoid, and an irregular polygon.

[0043] Regarding the lamp 10 for generating the starry sky effect, it can be a left front headlamp, a right front headlamp, or a through-type headlamp of a vehicle.

[0044] For example, the user can observe the starry sky effect 1 in the observation area 1 and the starry sky effect 2 in the observation area 2, and can observe the starry sky flickering effect when the user switches the observation angle between the observation area 1 and the observation area 2.

[0045] In the embodiments of the present application, the lamp for generating the starry sky effect realizes an innovative visual effect by combining the design of the LED light source, the multi-angle reflector, and the light filter plate. Specifically, the LED light source provides a basic light source, the multi-angle reflector is responsible for multi-angle reflection of the light, so that the light can pass through the plurality of through holes on the light filter plate at different angles and directions. In the above process, the light is dispersed and forms diversified light spots when passing through the light filter plate, thereby generating a starry sky-like visual effect in different observation areas.

[0046] Figure 2 The structure schematic diagram of the second embodiment of the lamp for generating the starry sky effect provided in the present application is shown. Based on the above-mentioned first embodiment, please refer to Figure 2 The multi-angle reflector 12 includes a mirror body 121 and a plurality of reflector surfaces 122.

[0047] The plurality of reflector surfaces 122 are arranged on one side of the mirror body 121, and the plurality of reflector surfaces 122 are used for multi-angle reflection of light generated by the LED light source 11 to generate different starry sky effects in a plurality of observation areas in front of the vehicle lamp.

[0048] For example, when the observation area is a front observation area, the starry sky effect 1 can be observed, when the observation area is a 30° rotation observation area, the starry sky effect 2 can be observed, and when the observation area is a 60° rotation observation area, the starry sky effect 3 can be observed.

[0049] In a possible design, the plurality of reflective surfaces 122 includes at least two groups of reflective surfaces, each group of reflective surfaces being configured to reflect light generated by the LED light source 11 at multiple angles to form different starry sky patterns.

[0050] For example, the starry sky effect 1 corresponds to the starry sky pattern 1. The starry sky pattern 1 is formed by reflecting light generated by the LED light source at multiple angles. The group of reflective surfaces can include reflective surfaces corresponding to the highlight reflective surfaces used to generate the starry sky effect 1.

[0051] Optionally, the field of view in front of the vehicle lamp can be divided into a plurality of observation regions according to a preset angle division rule and a preset height division rule. Each observation region can have a certain angle range or height range. For each observation region, a corresponding modeling or effect pattern (such as a starry sky pattern) is designed to determine the positions and angles of the plurality of reflective surfaces 122 in the multi-angle reflective mirror 12, so as to achieve the expected optical effect and visual experience.

[0052] Figure 3 An observation region division schematic diagram is provided for the embodiments of the present application. Please refer to Figure 3 For example, the left front headlamp of the vehicle can be divided into four observation regions according to the preset angle division rule in a clockwise direction. The four observation regions are observation region 1, observation region 2, observation region 3, and observation region 4. The preset angle of the observation region 1 can be 30°, the observation angle range is [0°, 30°), the preset angle of the observation region 2 can be 30°, the observation angle range is [30°, 60°), the preset angle of the observation region 3 can be 30°, the observation angle range is [60°, 80°), and the preset angle of the observation region 4 can be 10°, the observation angle range is [80°, 90°].

[0053] Figure 4 Another observation region division schematic diagram is provided for the embodiments of the present application. In Figure 3 Based on the embodiment shown in the above, please refer to Figure 4 Each of the plurality of observation regions obtained according to the preset angle division rule can be further divided in height. For example, the left front headlamp of the vehicle can be divided into four smaller observation regions according to the preset height 0.5 meters (m) and the observation region 1 obtained according to the preset angle division rule. The four smaller observation regions are observation region A, observation region B, observation region C, and observation region D. The observation height range of the observation region A is [0, 0.5m), the observation height range of the observation region B is [0.5m, 1m), the observation height range of the observation region C is [1m, 1.5m), and the observation height range of the observation region D is [1.5m, 2m].

[0054] It should be noted that reasonable angle division rules and height division rules can be formulated according to the historical experience of the user; in addition, different vehicle designs have different requirements for the field of view, so the preset angle division rules and the preset height division rules of the observation area can be adjusted according to the specific design requirements of the vehicle.

[0055] In the present application, the multi-angle reflector is composed of a mirror body and a plurality of reflector surfaces, the reflector surfaces are arranged on one side of the mirror body, and the angle and position of each reflector surface are designed to reflect the light emitted by the LED light source at multiple angles, thereby generating different starry sky effects in different observation areas in front of the vehicle lamp.

[0056] In addition, the multi-angle reflector reflects the light emitted by the LED light source at multiple angles, breaking the traditional static and single light effect performance of the lamp. By accurately adjusting the angle and position of the reflector surface, the lamp can present unique light and shadow effects in different observation areas. This design makes the light effect dynamically change with the user's viewing angle, presenting a visual effect like starlight flickering, bringing a lively and varied visual experience to the user, enhancing the interactivity and ornamental value of the lamp.

[0057] In one possible design, the LED light source 11 includes a plurality of LED lamps 111, and different reflector surfaces are used to reflect the light of different LED lamps 111.

[0058] Figure 5 The structure diagram of the LED light source provided in the present application is shown. Based on the above embodiment two, please refer to Figure 5 , the distance between the two adjacent LED lamps 111 in the LED light source 11 is any distance value selected from 8mm to 20mm.

[0059] For example, the distance between the two adjacent LED lamps in the LED light source is 8mm.

[0060] It should be noted that the distance between the LED lamps is not fixed. In addition to being able to select any distance value between 8mm and 20mm, the designer can also flexibly adjust this distance according to the specific design requirements, such as the overall height size H, the overall width L1, and the shape of the lamp. According to different application scenarios, the designer can select a suitable spacing to achieve the ideal lighting effect and visual aesthetics.

[0061] For example, in some cases, a smaller distance can provide a more uniform light distribution, while in other cases, a larger distance can be more beneficial for heat dissipation or to conform to a particular design style. Additionally, limitations in circuit design and installation space can also influence the choice of distance. Therefore, the setting of the distance should take into account various factors to ensure the overall functionality and reliability of the lamp.

[0062] In the embodiments of the present application, the design of the LED light source has high flexibility, allowing the distance between the LED lights to be adjusted according to specific needs. A suitable distance can be selected within the range of 8mm to 20mm to meet different application scenarios and design requirements.

[0063] In one possible design, the LED light source 11 further includes a printed circuit board 112, and the plurality of LED lights 111 are respectively arranged on the printed circuit board 112, and the printed circuit board 112 is used to control the on-off of the plurality of LED lights 111.

[0064] Optionally, through the circuit design on the printed circuit board, the LED lights can be precisely controlled to achieve the desired lighting effect.

[0065] For example, the printed circuit board can adjust the current of the LED lights to change their brightness, or achieve a combination of multiple colors by controlling the switching of different LEDs. In addition, the printed circuit board can also be integrated with other sensors or control systems to achieve more complex functions, such as dynamic light effects or intelligent lighting that responds to environmental changes.

[0066] Figure 6 The multi-angle mirror imaging principle diagram provided in the embodiments of the present application is shown in Figure 6 The printed circuit board (PCB) in the LED light source can control the turn-on of the LED lights to emit light. By adjusting the angle α of the mirror surface, the reflection angle β of the light can be adjusted, so that the light emitted by the LED lights is reflected to different human eye observation areas.

[0067] Specifically, the mirror surface can guide the light emitted by the LED lights to a specific direction, and finally form a clear image at the LED imaging position, for the human eye to view in the observation area, realizing the starry sky effect of bright and dark points alternating with each other.

[0068] In the embodiments of the present application, the on-off of the plurality of LED lights can be controlled through the printed circuit board, and in combination with the use of the multi-angle mirror, the reflection direction of the light can be flexibly adjusted to form a clear starry sky effect in a specific observation area, further enhancing the richness and level of visual experience.

[0069] Figure 7Structure diagram of the third embodiment of the lamp for generating starry sky effect provided in the present application. Based on the above-mentioned embodiment one or embodiment two, please refer to Figure 7 The lamp 10 for generating starry sky effect further comprises a mounting bracket 14.

[0070] The mounting bracket 14 is used for fixing the LED light source 11, the multi-angle reflector 12 and the light filter plate 13.

[0071] Optionally, the light filter plate 13 is a paint-sprayed laser-engraved light filter plate.

[0072] In a possible design, the material of the light filter plate 13 is glass, quartz stone or acrylic plate; and the surface of the light filter plate 13 is sprayed with a light-shielding coating. The light-shielding coating can improve the contrast of the starry sky effect, make the bright spots more prominent, thereby enhancing the sense of level and depth of the visual effect. In addition, the light-shielding coating can also play a role in protecting the surface of the light filter plate 13, preventing scratches, dust and other environmental factors from damaging the light filter plate 13.

[0073] Optionally, the light-shielding coating can be a black matte coating, a metal oxide coating or a nano material coating. The black matte coating can effectively absorb excess light, reduce reflection and glare, and improve the contrast and clarity of the starry sky effect; the metal oxide coating can provide wear resistance and corrosion resistance, while also controlling the reflection and transmission of light, enhancing the durability and optical performance of the lamp; and the nano material coating has excellent optical performance and self-cleaning function, which can further optimize the distribution and intensity of light, while reducing the adhesion of dust and dirt. By selecting a suitable light-shielding coating, the lamp can achieve more excellent optical effect and longer service life.

[0074] In the embodiments of the present application, a mounting bracket is further provided in the lamp for generating starry sky effect, which is used to stably fix the LED light source, the multi-angle reflector and the light filter plate, and ensure that the components maintain the correct relative positions during use. Thus, the structure stability of the lamp is improved, and the installation and maintenance of the lamp are facilitated.

[0075] Figure 8 Structure diagram of an example of the lamp for generating starry sky effect provided in the embodiments of the present application. Please refer to Figure 8 The multi-angle reflector can comprise an LED light source, a multi-angle reflector, a paint-sprayed laser-engraved light filter plate and a mounting bracket. The LED light source comprises a plurality of LED lamps and a printed circuit board.

[0076] By using multi-angle reflectors, the light emitted by the LED light source can be redistributed to different angles. Compared with existing technologies that rely on electronic control units to control a large area of ​​LED dot matrix to achieve a twinkling starry sky effect, the luminaire provided by this solution can achieve a twinkling starry sky effect without electronic control units and complex animation control.

[0077] Figure 9 This is a schematic diagram illustrating the starry sky effect provided in an embodiment of this application. Please refer to [link / reference]. Figure 9 Observation area 1 can see starry sky effect 1, and observation area 2 can see starry sky effect 2.

[0078] Optionally, when designing multi-angle reflectors to achieve a starry sky effect within the observation area, optical software can be used for design. By adjusting each reflector surface and using computer-aided software for simulation, the final effect can be verified and confirmed, thereby ensuring the accuracy of the design and the desired visual presentation.

[0079] This application also provides a vehicle including the lighting fixtures described in any of the above embodiments for generating a starry sky effect. By adopting this innovative lighting fixture design in the vehicle, the vehicle can present a unique starry sky visual effect when driving at night, which not only enhances the vehicle's aesthetics and recognizability but also increases the driving pleasure and the user's visual experience.

[0080] Furthermore, this lighting design achieves dynamic light and shadow changes through multi-angle reflectors and flexibly adjustable LED light sources, giving the vehicle a starlight-like effect from different viewing angles. This design not only breaks away from the static, single-effect performance of traditional car lights but also reduces reliance on complex electronic control systems through the combination of physical optical components, thereby lowering system complexity and cost. It provides higher reliability and a longer lifespan while enhancing visual appeal.

[0081] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the embodiments disclosed herein.
