Description

Technical Field

[0001] The utility model relates to the field of vehicle lighting, and more specifically, to a tunnel type lamp structure and a vehicle lamp thereof. Background Art

[0002] Traditional car lights generally reflect light through reflectors, forming a two-dimensional image in the observer's vision. It is not three-dimensional and vivid, and cannot make people feel distance and depth. It can only be used as a signal light and cannot play an effective role in car body decoration.

[0003] In the related art, there is a tunnel-type vehicle lamp that can produce a number of tunnel lighting effects arranged in a ring shape or a step shape, and has obvious recognition in addition to complying with regulations.

[0004] Chinese patent document CN 208222397U discloses a tunnel-type combined taillight, which realizes a tunnel effect by setting a light-transmitting side panel and a light-blocking member in a stepped structure. However, since the position of the light source in the patent is fixed, the relative position and distance between the light-transmitting side panel and the light source of each layer of the tunnel are quite different, resulting in a large difference in brightness of each layer of the tunnel, and the three-dimensional effect is not obvious enough.

[0005] The present application aims to improve the lighting effect and proposes a tunnel lamp structure and a vehicle lamp thereof, so that each layer of the tunnel has sufficient brightness and enhances the three-dimensional effect. Summary of the invention

[0006] The utility model overcomes the drawback of large brightness differences in tunnel light effects produced by existing tunnel taillights, and provides a tunnel light structure and a vehicle light thereof, so that each layer of the tunnel has sufficient brightness, thereby improving the three-dimensional effect.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A tunnel light structure, comprising:

[0009] Mounting seat;

[0010] A light source is arranged on the bottom surface of the mounting base and is used to generate light;

[0011] A light expansion part, arranged above the light source, for diffusing light;

[0012] A first reflecting surface, used for reflecting light;

[0013] A second reflecting surface, used for reflecting and refracting light;

[0014] Among them, the light source expansion part, the first reflecting surface, the second reflecting surface and the opaque side wall of the mounting seat form a closed reflecting cavity. After the light enters the reflecting cavity through the expansion part, it leaves the reflecting cavity through several reflections and refractions to form several apertures.

[0015] The tunnel-like aperture effect refers to the ability to form a number of strip-shaped lighting effects on the surface of the lamp body, thereby having better recognition. Generally, the lighting effect often has a certain curvature, and each lighting effect is arranged in a concentric or quasi-concentric manner.

[0016] The present application uses several reflections and corresponding refractions to achieve several strip lighting effects with a single light source. Specifically, the light source generates light in various directions through the light expansion unit. Then, it is directed upward to the second reflection surface, and refracted at a specific angle to produce the brightest light effect closest to the light source; the remaining light is reflected to the first reflection surface, and then reflected again, and a part of the light meets a specific angle and is refracted from the second reflection surface; the above steps are repeated several times to form several strip lighting effects.

[0017] Through the structure, the second reflective surface of the present application does not need to be aluminum-plated, thereby improving the transmittance.

[0018] The distinguishing feature of the present application is that a reflective cavity is provided, a first reflective surface and a second reflective surface are integrated, and the light source is arranged outside the reflective cavity, and then the light diffuser is used to diverge the light, so that each strip light effect has sufficient brightness and corresponding uniformity, and has obvious recognition.

[0019] Preferably, at least a portion of the side wall of the mounting seat forming the reflective cavity is a light shielding portion, and the light shielding portion is used to absorb light. The light shielding portion is used to absorb the light that cannot be emitted from the second reflective surface during the aforementioned predetermined reflection-refraction process, and avoids the light from being emitted from between the preset light effect light strips after being emitted to the side wall of the mounting seat, resulting in the generation of stray light, so that the distinction between light effects and light effects is clearer, and the recognition is improved.

[0020] Preferably, the light shield is arranged near the light expansion part, where the light is strongest, and by being arranged at this position, the absorption of stray light can be effectively improved.

[0021] Preferably, the light expansion part is located at the lower edge of the reflective cavity, and the distance from the first reflective surface to the second reflective surface gradually decreases from the lower edge to the upper edge. The structure makes the light effects generated closer to the light source thicker and farther away from the light source thinner. This setting can make the overall effect have a significant three-dimensional sense, improve recognition, and increase viewing angle.

[0022] Preferably, the light sources are arranged in a trapezoidal shape in a matrix or strip shape, and the shape of the light expansion part is adapted to the direction in which the light sources are arranged. The structure enables the generated light effect strip to also have an arc shape, creating a tunnel-like feeling, and the aforementioned features can enhance the overall depth of the lamp body and improve the viewing angle.

[0023] Preferably, the reflective cavity has a central axis, and the farther the light expansion part is from the central axis, the lower the light expansion part is. The structure is used to adjust the amount and angle of incident light, so that the light effect band is thinner the farther away from the central axis, which can also help improve the perception of the taillight effect and the viewing angle.

[0024] Preferably, the light expansion portion is higher than the first reflecting surface near the central axis, and is lower than the first reflecting surface at the farthest distance from the central axis.

[0025] A tunnel-type vehicle light comprises a tunnel-type light structure as described above, wherein the light source is mounted on a PCB board, the mounting seat is a mounting frame, the mounting frame has an extension plate extending in a lateral direction, the extension plate forms a first reflection surface, a lens is mounted on the top of the mounting frame, the bottom surface of the lens forms a second reflection surface, and the light expansion part is a diffusion cover mounted on the mounting frame. A reflection cavity is formed by the extension plate, the lens and the diffusion cover, multiple reflections and refractions are achieved, and a tunnel-like light effect is generated.

[0026] Preferably, the mounting frame is further provided with a modeling part outside the reflective cavity, the modeling part is provided with a modeling light source having a PCB board, the modeling part is provided with a modeling light-transmitting cover, and the light generated by the modeling light source is emitted through the modeling light-transmitting cover. The modeling part and the corresponding modeling light source further enhance the recognition and aesthetics. As a taillight installed on a two-wheeled vehicle, the structure enhances the range of the viewing angle, and is easy to be recognized by external motor vehicles or non-motor vehicles and people.

[0027] Preferably, the material of the shaped light-transmitting cover is PMMA or PC.

[0028] Compared with the prior art, the beneficial effects of the utility model are:

[0029] (1) The light source is placed outside the reflective cavity and cooperates with the shading part to make the light diffusion more sufficient and uniform, and the light effect formed is more uniform;

[0030] (2) The lens (second reflective surface) does not need to be aluminum-plated, which improves transmittance and makes the light effect brighter;

[0031] (3) The shape of the first reflective surface and the light expansion part makes the light effect band gradually thinner from the middle to the edge, which has good recognition and viewing angle. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Example:

[0046] Ginseng Figure 1 , 4 and 5. A tunnel light structure comprising:

[0047] Mounting seat 1;

[0048] A light source 2 is disposed on the bottom surface of the mounting base 1 and is used to generate light;

[0049] The light expansion unit 3 is arranged above the light source 2 and is used to diffuse the light;

[0050] A first reflecting surface 4, used for reflecting light;

[0051] The second reflecting surface 5 is used for reflecting and refracting light;

[0052] Among them, the light expansion part 3 of the light source 2, the first reflecting surface, the second reflecting surface and the opaque side wall of the mounting seat 1 form a closed reflecting cavity 6. After the light enters the reflecting cavity 6 through the light expansion part 3, it leaves the reflecting cavity through several reflections and refractions to form several apertures.

[0053] Among them, at least a part of the side wall of the mounting base 1 forming the reflective cavity 6 is a shading portion 7, and the shading portion 7 is used to absorb light. The shading portion 7 is used to absorb the light emitted from the second reflective surface 5 that cannot be emitted during the aforementioned predetermined reflection-refraction process, so as to avoid the light being emitted from between the preset light effect light strips after being emitted to the side wall of the mounting base 1, resulting in the generation of stray light, making the distinction between light effects and light effects clearer and improving recognition. The cross-section of the shading portion 7 is trapezoidal, and the light emitted from the top surface and one side surface participates in the reflection-refraction. The light generated on the other side is not needed, therefore, a shading portion 7 is provided on the corresponding side wall to absorb light to avoid the generation of reflected light, thereby polluting the preset light path and forming stray light.

[0054] The light sources 2 are arranged in a trapezoidal shape in a dot matrix or a belt, and the shape of the light expansion part 3 is adapted to the direction in which the light sources 2 are arranged. The structure enables the generated light effect belt to also have an arc shape, creating a tunnel-like feeling. In combination with the aforementioned features, the depth of the lamp body as a whole can be increased, and the viewing angle can be increased. The light expansion part 3 is located at the lower edge of the reflective cavity 6, and the distance from the first reflective surface 4 to the second reflective surface 5 gradually decreases from the lower edge to the upper edge. The structure enables the generated light effects to be thicker closer to the light source 2 and thinner farther away. This setting can make the overall effect have a significant three-dimensional sense, improve recognition, and improve viewing angle.

[0055] Ginseng Figure 1 , 4 As shown, the reflective cavity 6 has a central axis, which divides the entire structure equally on the left and right. The farther the light expansion part 3 is from the central axis, the lower the light expansion part 3 is. The structure is used to adjust the amount and angle of the incident light, so that the light effect band farther away from the central axis is thinner, which can also help improve the perception of the taillight effect and increase the viewing angle. In some embodiments, reference Figure 5 As shown, the light diffusing part 3 is higher than the first reflecting surface 4 near the central axis, and is lower than the first reflecting surface 4 at the farthest distance from the central axis. The top surface of the entire light diffusing part is continuously transitioned without any jump steps. This structure enables the light to be emitted from the top and side surfaces near the central axis, while only the top surface of the light diffusing part 3 can emit light far away. By adjusting the illumination and combining the distance adjustment from the first reflecting surface 4 to the second reflecting surface 5 mentioned above, the brightness of the unit position remains unchanged while the light effect band becomes narrower, thereby improving the uniformity of the same light effect band.

[0056] The tunnel-like aperture effect refers to the ability to form a number of strip-shaped lighting effects on the surface of the lamp body, thereby having better recognition. Generally, the lighting effect often has a certain curvature, and each lighting effect is arranged in a concentric or quasi-concentric manner.

[0057] The present application uses several reflections and corresponding refractions to achieve several strip lighting effects with a single light source 2. Specifically, the light source 2 generates light in various directions through the light expansion unit 3. Then, it is directed upward to the second reflection surface 5, and refracted at a specific angle to produce the brightest light effect closest to the light source 2; the rest of the light is reflected to the first reflection surface 4, and then reflected again, and another part of the light meets the specific angle and is refracted from the second reflection surface 5; the above steps are repeated several times to form several strip lighting effects.

[0058] Through the above structure, the second reflective surface 5 of the present application does not need to be aluminum-plated, thereby improving the transmittance.

[0059] The distinguishing feature of the present application is that a reflective cavity 6 is provided, a first reflective surface 4 and a second reflective surface 5 are integrated, and the light source 2 is arranged outside the reflective cavity 6, and the light expansion part 3 is used to diverge the light, so that each strip light effect has sufficient brightness and corresponding uniformity, and has obvious recognition.

[0060] Ginseng Figure 2 , 3 , 4 and 5, based on the aforementioned tunnel lamp structure, there is a tunnel-type vehicle lamp, including a tunnel-type lamp structure as described above, wherein the light source 2 is mounted on a PCB board 8, the mounting seat 1 is a mounting frame 9, the mounting frame 9 has an extension plate 10 extending in the lateral direction, the extension plate 10 forms a first reflection surface 4, a lens 11 is mounted on the top of the mounting frame 9, the bottom surface of the lens 11 forms a second reflection surface 5, and the light expansion part 3 is a diffusion cover 12 mounted on the mounting frame 9. A reflection cavity 6 is formed by the extension plate 10, the lens 11 and the diffusion cover 12, and multiple reflections and refractions are achieved to produce a tunnel-like light effect. The light shield 16 is mounted on the side wall of the mounting frame 9 to form a reflection cavity 6.

[0061] The mounting frame 9 is further provided with a modeling part 14 outside the reflection cavity 6, and the modeling part 14 is provided with a modeling light source 13, which is also installed on the PCB board 8. The modeling part 14 is provided with a modeling light-transmitting cover 15, and the light generated by the modeling light source 13 is emitted through the modeling light-transmitting cover 15. The modeling part 14 and the corresponding modeling light source 13 further improve the recognition and aesthetics. As a taillight installed on a two-wheeled vehicle, the structure improves the range of the viewing angle, which is easy to be recognized by external motor vehicles or non-motor vehicles and people.

[0062] The material of the shaped light-transmitting cover 15 is PMMA or PC. The shaped light-transmitting cover 15 and the lens 11 and the corresponding decorative parts are integrated into a structure and can be produced by injection molding. The assembly form is a conventional method, including buckles, screws, and melt glue.
