[0002] Ambient lighting can provide a premium ambiance for the car cabin and enable scene-based functions such as warnings and indications. Current market models generally use a lamp head + light guide + bracket structure for ambient lighting, which can only achieve single direct light emission or single reflected light emission. When both direct and reflected effects are required, two sets of ambient lights are usually needed.

[0003] No effective solution has yet been proposed to address the aforementioned technical issues. Utility Model Content

[0004] The main objective of this invention is to provide a lighting device and a vehicle having it, in order to solve the problem of the limited direct or reflective effects of ambient lighting in vehicles in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a lighting device is provided, comprising: a light-transmitting support structure having a light-emitting component, the light-emitting component including at least a light source accommodating space and a light source module disposed within the light source accommodating space, at least a portion of the sidewalls of the light source accommodating space being a light-transmitting wall, and at least a portion of the light emitted by the light source module being able to pass through the light-transmitting wall; and a light effect conversion structure including at least a light-transmitting part and a reflective part, the light-transmitting part and the reflective part forming a light-emitting component accommodating space, the light-emitting component being disposed within the light-emitting component accommodating space, wherein a portion of the light emitted by the light-emitting component is emitted through the light-transmitting part, and a portion of the light emitted by the light-emitting component is emitted after being reflected by the reflective part.

[0006] Furthermore, the light source module is used to generate a line light source.

[0007] Furthermore, the light source module includes: a lamp head; a light guide strip connected to the lamp head, wherein the point light source generated by the lamp head is converted into a line light source through the light guide strip; wherein the light guide strip is located within the light source accommodating space.

[0008] Furthermore, the light-transmitting wall includes a first light-transmitting area and a second light-transmitting area, wherein the first light-transmitting area is disposed adjacent to the reflective part, the second light-transmitting area is disposed adjacent to the light-transmitting part, and the first light-transmitting area and the second light-transmitting area are disposed adjacent to each other along the circumference of the light source module.

[0009] Furthermore, the light effect conversion structure includes: a first decorative element having a reflective portion, the first decorative element being located on one side of the light-transmitting support structure and connected to the light-transmitting support structure; and a second decorative element having a light-transmitting portion, the second decorative element being located on the other side of the light-transmitting support structure and connected to the light-transmitting support structure.

[0010] Furthermore, the reflective part includes a diffuse reflective surface.

[0011] Furthermore, the light-transmitting part includes a light-transmitting surface and a light-transmitting hole.

[0012] Furthermore, the light-transmitting support structure is made of a diffusion material.

[0013] Furthermore, the light source module is an LED light strip.

[0014] According to another aspect of the present invention, a vehicle is provided, the vehicle having a lighting device, the lighting device being the aforementioned lighting device.

[0015] By applying the technical solution of this utility model, the light-transmitting support structure itself has a light source accommodating space, within which a light source module is installed, providing support for the light source module. Furthermore, the sidewalls of the light source accommodating space are designed as light-transmitting walls, allowing light emitted from the light source module to pass through and be emitted in different directions. The light-transmitting walls of the light-transmitting support structure allow light emitted from the light source module to illuminate different parts of the light conversion structure. The light-transmitting part of the light conversion structure can project the light emitted from the light source module in a straight line, forming direct light, while the reflective part of the light conversion structure can reflect the light emitted from the light source module, forming reflected light. Through the arrangement of the light-transmitting and reflective parts in the light conversion structure, direct and reflected light are cleverly combined. That is, with only one light source module working in conjunction with the light-transmitting support structure and the light conversion structure, both direct and reflected light emission effects can be achieved simultaneously, realizing natural light diffusion. Applying the lighting device of this embodiment to a vehicle can create a more uniform and softer lighting environment inside the vehicle, effectively alleviating driver visual fatigue and improving driving comfort and safety.

[0026] Combination Figures 1 to 3 As shown, according to a specific embodiment of this application, a lighting device is provided.

[0027] Specifically, such as Figure 1As shown, the lighting device includes a light-transmitting support structure 3 and a light-effect conversion structure. The light-transmitting support structure 3 has a light-emitting component. The light-emitting component includes at least a light source accommodating space and a light source module disposed in the light source accommodating space. At least a portion of the sidewalls of the light source accommodating space are light-transmitting walls, and at least a portion of the light emitted by the light source module can pass through the light-transmitting walls. The light-effect conversion structure includes at least a light-transmitting part 4 and a reflective part 6. A light-emitting component accommodating space is formed between the light-transmitting part 4 and the reflective part 6. The light-emitting component is disposed in the light-emitting component accommodating space. Part of the light emitted by the light-emitting component is emitted through the light-transmitting part 4, and part of the light emitted by the light-emitting component is emitted after being reflected by the reflective part 6.

[0028] Applying the technical solution of this embodiment, the light-transmitting support structure 3 itself has a light source accommodating space, and a light source module is set in the light source accommodating space, so that the light source accommodating space provides support for the light source module. On this basis, the side wall of the light source accommodating space is set as a light-transmitting wall, which allows the light emitted by the light source module to pass through the light-transmitting wall and emit light in different directions. The light-transmitting wall of the light-transmitting support structure 3 allows the light emitted by the light source module to pass through the light-transmitting wall and illuminate different parts of the light effect conversion structure. The light-transmitting part 4 of the light effect conversion structure can shoot out the light emitted by the light source module in a straight line to form direct light. The reflective part 6 of the light effect conversion structure can reflect the light emitted by the light source module to form reflected light. Through the setting of the light-transmitting part 4 and the reflective part 6 in the light effect conversion structure, only one light source module, together with the light-transmitting support structure 3 and the light effect conversion structure, can simultaneously achieve both direct and reflected light emission effects, realizing the natural diffusion of light. Applying the lighting device in this embodiment to a vehicle can create a more uniform and soft lighting environment inside the vehicle, effectively relieving driver visual fatigue and improving driving comfort and safety.

[0029] It should be noted that, as Figure 1 As shown, the light source accommodating space of the light-transmitting support structure 3 is configured as a concave structure. The inner side of the concave structure of the light-transmitting support structure 3 is the first side, and the outer wall side of the concave structure of the light-transmitting support structure 3 is the second side. The light source module is set on the inner side of the concave structure of the light-transmitting support structure 3, so that the light-transmitting support structure 3 can form a stable support for the light source module. The positions of the light-transmitting part 4 and the reflective part 6 can be flexibly set on the second side of the light-transmitting support structure 3 according to the vehicle body structure and user needs. Based on its flexibility, while providing an interior atmosphere, it can also improve the performance of the lighting device and enhance the practicality of the lighting device.

[0030] Preferably, such as Figure 1 , Figure 3As shown, the light source module is used to generate a line light source. Using a line light source provides a more uniform light distribution, avoiding the problems of local over-brightness or under-brightness and light spots that may occur with point light sources. At the same time, the light-transmitting support structure 3 is also set as a linear support structure that matches the line light source, so that the light generated by the line light source can be evenly emitted to the light conversion structure, so that every corner of the vehicle can receive comfortable lighting.

[0031] Furthermore, such as Figure 3 As shown, the light source module includes a lamp head 1 and a light guide strip 2. The light guide strip 2 is connected to the lamp head 1, and the point light source generated by the lamp head 1 is converted into a line light source through the light guide strip 2. The light guide strip 2 is located within the light source housing space. The setting of the light guide strip 2 not only converts the point light source into a line light source, but also realizes the diffusion of light in the light guide strip 2. The light guide strip 2 can effectively capture the light emitted by the lamp head 1 and diffuse it evenly along a predetermined path (i.e., the path extended by the light guide strip 2), ultimately forming a line light source. The line light source emitted by the light guide strip 2 can create a more delicate and flowing light effect through the light effect conversion structure, thereby enhancing the aesthetic atmosphere inside the vehicle.

[0032] Furthermore, such as Figure 2 As shown, the light-transmitting wall includes a first light-transmitting area 8 and a second light-transmitting area 9. The first light-transmitting area 8 is located adjacent to the reflective part 6, and the second light-transmitting area 9 is located adjacent to the light-transmitting part 4. The first light-transmitting area 8 and the second light-transmitting area 9 are arranged adjacent to each other along the circumference of the light source module. The first light-transmitting area 8 and the second light-transmitting area 9 are respectively located on the second side of the light-transmitting support structure 3, that is, one side wall and the bottom wall along the circumference of the concave structure. The first light-transmitting area 8 is located adjacent to the light-transmitting part 4, so that light passes through the first light-transmitting area 8 of the light-transmitting support structure 3 and shines on the light-transmitting part 4, forming direct light rays. The second light-transmitting area 9 is located adjacent to the reflective part 6, so that light passes through the second light-transmitting area 9 of the light-transmitting support structure 3 and shines on the reflective part 6, forming reflected light rays. This structural partitioning design can achieve precise control of light, so that reflected light and direct light can be distributed according to a preset pattern, thereby achieving the combination of direct light and reflected light to form a more uniform light distribution, which is suitable for personalized lighting needs inside vehicles.

[0033] Furthermore, such as Figure 1As shown, the light conversion structure includes a first decorative element 7 and a second decorative element 5. The first decorative element 7 has a reflective portion 6 and is located on one side of the light-transmitting support structure 3 and connected to it. The second decorative element 5 has a light-transmitting portion 4 and is located on the other side of the light-transmitting support structure 3 and connected to it. The use of the first decorative element 7 and the second decorative element 5 can enhance the aesthetics of the lighting device and improve the warmth of the interior atmosphere. By placing the light-transmitting portion 4 on the second decorative element 5 and the reflective portion 6 on the first decorative element 7, secondary light conversion can be achieved without the need for additional components, saving space in the lighting device, improving its practicality, and adding artistic charm to the interior.

[0034] Optionally, the reflective part 6 includes a diffuse reflective surface, and the light-transmitting part 4 includes a light-transmitting surface and a light-transmitting aperture, and / or, the light-transmitting part 4 is a light-transmitting surface. The selection of the diffuse reflective surface, the light-transmitting surface, and the light-transmitting aperture can adjust the nature of the light according to specific needs. The diffuse reflective surface is suitable for scenarios requiring soft and uniform light, while the light-transmitting surface and the light-transmitting aperture are suitable for scenarios requiring more direct and focused light. At the same time, the combination and flexible arrangement of the diffuse reflective surface and the light-transmitting surface and the light-transmitting aperture can improve the flexibility and control precision of the vehicle interior lighting and adapt to various lighting needs inside the vehicle.

[0035] It should be noted that the positions of the reflective part 6 and the light-transmitting part 4 can be interchanged. Alternatively, different side walls of the light-transmitting support structure 3 can be set as reflective or light-transmitting parts according to user needs. In other words, different combinations of one reflective surface and one light-transmitting surface, two reflective surfaces, or two light-transmitting surfaces can be selected according to user needs. For example, the first and second sides of the light-transmitting support structure 3 in the passenger position can be set as reflective parts to provide a comfortable resting environment; the first and second sides of the light-transmitting support structure 3 in the driver's and passenger's positions can be set as a combination of one reflective surface and one light-transmitting surface to provide soft light while reducing visual fatigue.

[0036] Optionally, the light-transmitting support structure 3 is made of a diffuser material. The use of diffuser material can further improve the uniformity and softness of light, creating a quiet and harmonious in-vehicle atmosphere. Moreover, because the diffuser material has a high light diffusion rate and a low light absorption rate, it can ensure that light is fully diffused when it penetrates the light-transmitting wall, reducing light spots and glare, reducing visual fatigue of passengers, and improving riding comfort and satisfaction.

[0037] Optionally, the light source module is an LED light strip. LED light strips have advantages such as low energy consumption, long lifespan, high brightness, and rich colors. They can be used for a long time and are suitable for various lighting needs, such as interior ambient lighting, reading lighting, and safety lighting. They can effectively reduce vehicle energy consumption, reduce the maintenance cost of vehicle ambient lighting, and improve the reliability of the lighting system.

[0038] According to another specific embodiment of this application, a vehicle is also provided, the vehicle having a lighting device, which is the lighting device in the above embodiments. The vehicle can be an electric vehicle, a hybrid vehicle, etc.

[0039] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0040] 1) Achieve both reflective and direct ambient lighting effects using a set of light elements.

[0041] 2) The lighting device has the characteristics of low cost and good light emission effect.

[0042] 3) This lighting device is highly scalable, such as an exterior position light with a similar light-emitting effect, or a single light source that can simultaneously achieve the effects of an interior reading light and an ambient light.

[0043] This application also provides a preferred embodiment of a lighting device, which is an automotive ambient lighting solution that achieves both direct and reflected light emission effects using a set of light sources, thereby improving the ambient lighting effect in the car cabin and offering significant cost advantages.

[0044] Specifically, the lighting device includes a lamp head 1, a light guide strip 2, a light-transmitting support structure 3, a second decorative component 5, and a first decorative component 7. The lamp head 1 has a communication function and can provide RGB light source. The lamp head 1 and the light guide strip 2 form a light source module, which is snapped into the light-transmitting support structure 3. The light-transmitting support structure 3 is a diffusion material, which can realize light emission from both the first light-transmitting area 8 and the second light-transmitting area 9. The second decorative component 5 can realize a light-transmitting surface of any shape and pattern through jet laser engraving. The first decorative component 7 can realize a diffuse reflection surface with various effects through processes such as etching, laser engraving, coating, and spraying.

[0045] The assembly of lamp head 1, light guide strip 2 and light-transmitting support structure 3 is assembled with the first decorative part 7 and the second decorative part 5. Light is emitted through the first light-transmitting area 8 and the second light-transmitting area 9 of the light-transmitting support structure 3. The light hits the first decorative part 7 and the second decorative part 5, forming a reflective and direct ambient lighting effect.
