[0034] In the current 3D lighting design in the industry, optical components use thick-walled light guides or paint-spraying laser engraving solutions. The thick-walled solutions for optical components are heavy and costly, while the paint-spraying laser engraving solutions for optical components have poor consistency in the spray-spraying laser engraving process and laser engraving takes a long time.
[0035] To this end, the utility model proposes a vehicle lamp structure, aiming to provide a thin-walled three-dimensional lighting solution to reduce the weight and cost of the product; in addition, no manual secondary processing is required, and the processing cycle is short.
[0036] Reference Figures 1 to 7 In one embodiment of the utility model, the vehicle lamp structure 10 includes a bottom shell 20, a mask 30, a mapping member 50 and a light-transmitting member 60, the mask 30 and the bottom shell 20 are covered to form a accommodating cavity 21; the bottom shell 20 can be used as a part of the vehicle body, or it can be a component connected to the vehicle body separately, the mask 30 is made of a light-transmitting material, so that light can be received by the outside world; specifically, the vehicle lamp structure 10 can be set at the front headlight of the vehicle; and or, the taillight located at the rear of the vehicle, the taillight usually includes a brake light, a width indicator light, a reversing light and a rear fog light, etc.; and or, the turn signal located on the side of the four corners of the vehicle.
[0037] Reference Figure 2 , the light source assembly 40 is disposed in the accommodating cavity 21 and is used to emit light; the mapping member 50 is disposed in the accommodating cavity 21, the mapping member 50 is light-proof, and the mapping member 50 has a mapping surface 51 facing the mask 30; refer to Figure 4 and Figure 7 The light-transmitting member 60 is stacked with the mapping member 50, and the light-transmitting member 60 is provided with a light-emitting portion 61 with a graphic structure, and the light-transmitting member 60 is used to receive the light and emit the light from the light-emitting portion 61; the mapping member 50 is provided with interpenetrating grooves, and the light-emitting portion 61 passes through the grooves, and part of the light-emitting portion 61 exceeds the mapping surface 51, and the light emitted by the light-emitting portion 61 and part of the light mapped to the mapping surface 51 together form a luminous group to achieve a three-dimensional luminous effect.
[0038] In one embodiment, the light source assembly 40 is connected to the bottom shell 20, and the bottom shell 20 is provided with a reflective coating. The reflective coating disperses the light emitted by the light source assembly 40 and then emits it to the mapping member 50. The mapping member 50 is connected to the bottom shell 20. The mapping member 50 is light-proof, and can be sprayed with a light-proof coating on the surface facing the light source assembly 40; or it can be light-proof as a whole, so that the light enters the light-transmitting member 60 at the location from the embedded groove position. The light-transmitting member 60 is optically processed, and the light-emitting portion 61 illuminated by the light is in a graphic structure. The graphic structure can be numbers, such as 1, 2, 3; or text; or letters, such as G, E, E, etc., or graphics; or a combination of the above. After the light-emitting portion 61 is illuminated, the mapping surface 51 is equivalent to the "water surface" and maps a corresponding shape. The light emitted by the light-emitting portion 61 and the light partially mapped to the mapping surface 51 together form a luminous group to achieve a three-dimensional luminous effect.
[0039] In another embodiment, the light source assembly 40 , the mapping member 50 , and the light-transmitting member 60 are all arranged in the accommodating cavity 21 , and their positions and / or connection relationships are adjusted according to design requirements.
[0040] In one embodiment, the light-transmitting member 60 is stacked with the mapping member 50 , the mapping member 50 is provided with interpenetrating embedding grooves, the light-emitting portion 61 passes through the embedding grooves, and then is fixed by gluing.
[0041] In another embodiment, in order to improve the integrity, prevent light leakage at the light emitting position, and improve the quality of light, the light emitting portion 61 is penetrated by the embedding groove, the light-transmitting member 60 and the mapping member 50 are stacked, and then the insert is injection molded. When the light emitting portion 61 is lit, the observer sees the letters or graphics of the light emitting portion 61 through the mask 30, and under the support of the mapping surface 51, the light emitted by the light emitting portion 61 and the light partially mapped to the mapping surface 51 together form a luminous group to produce a three-dimensional luminous effect, thereby presenting a three-dimensional sense of the original plane graphics formed by the light emitting portion 61. When the light emitted by the light emitting portion 61 is irradiated on the mapping surface 51, the light will be reflected and refracted according to the shape and texture of the mapping surface 51, forming various light paths. In these light paths, part of the light will directly irradiate into the eyes of the observer, while the other part of the light will be reflected and refracted by the mapping surface 51 before irradiating into the eyes of the observer. The light from the light emitting portion 61 and the light from these different paths will form different light intensities and color distributions in the eyes of the observer, thereby presenting a three-dimensional effect. This three-dimensional lighting effect can enhance the visual impact of the graphics to highlight the product features or brand image.
[0042] The technical solution of the utility model is installed on the vehicle through the bottom shell 20, and the bottom shell 20 and the mask 30 are covered to form a receiving cavity 21. The light source assembly 40 is used to emit light and is arranged in the receiving cavity 21; the traditional solution adopts a 3D stereoscopic lighting design and adopts a thick-walled light guide or a spray-painted laser-engraved optical element solution. For the thick-walled light guide solution, since it uses thicker optical elements, this undoubtedly increases the weight of the whole vehicle and occupies a larger lamp structure space, resulting in a higher cost per lamp; in order to reduce product weight and cost, this solution A mapping member 50 is arranged in the accommodating cavity 21, the mapping member 50 is light-proof, and the mapping member 50 has a mapping surface 51 facing the mask 30; the light-transmitting member 60 is stacked with the mapping member 50, the mapping member 50 is provided with interpenetrating embedding grooves, the light-emitting portion 61 penetrates the embedding grooves, the light-transmitting member 60 is provided with a light-emitting portion 61 in a graphic structure, and a portion of the light-emitting portion 61 exceeds the mapping surface 51, the light-transmitting member 60 receives the light, and transmits the light from the light-emitting portion 61 to the mask 30. The light emitted by the light emitting portion 61 and the light partially mapped to the mapping surface 51 together form a luminous group to achieve a three-dimensional luminous effect; compared with the thick-walled light guide solution, in order to ensure optical uniformity, the thick wall size needs to be increased (that is, the size in the direction from the light source to the exit surface needs to be increased), and the injection molding process of the thick-walled part is long; this solution adopts the mapping part 50 and the light-transmitting part 60 to cooperate, and the light emitted by the light emitting portion 61 and the light partially mapped to the mapping surface 51 together form a luminous group to achieve a three-dimensional luminous effect. The light-emitting effect of the whole body can be achieved; thereby, the wall thickness, weight and cost can be reduced; in addition, compared with the spray-paint laser engraving solution, there are problems such as poor consistency in the spray-paint laser engraving process, unclear luminous boundaries, and long laser engraving time and high labor cost. In this solution, the light-transmitting member 60 is provided with a light-emitting portion 61 with a graphic structure, and the mapping member 50 is provided with interlocking embedding grooves, and the light-emitting portion 61 is penetrated by the embedding grooves. After the light-transmitting member 60 and the mapping member 50 are formed, no secondary processing is required by humans, and the conventional optical element processing technology is adopted, and the cycle is short.
[0043] Reference Figure 2 and Figure 3In a further solution, in order to achieve a good dispersion effect on the light source and low cost, the vehicle lamp structure 10 further includes a reflector 70 disposed in the accommodating cavity 21, and the reflector 70 is connected to the mapping member 50, and is used to diffusely reflect the light generated by the light source assembly 40 and then emit it to the light-transmitting member 60. The reflector 70 adopts an optical design, and disperses the light of the light source assembly 40 through a separate reflector 70 to ensure the light-emitting effect, thereby improving the three-dimensional light-emitting effect. Compared with the thick-walled light guide or the spray-painted laser engraving solution, both of which are single optical designs, this solution forms secondary optical imaging by superimposing the light distribution structure of the reflector 70, the light-transmitting member 60 and the mapping member 50, and has a visual effect that cannot be achieved by a single light distribution structure. In this way, this solution has lower cost and lighter weight; it can make the lighting effect good and the size small, making it easier to realize the design concept.
[0044] Furthermore, in order to ensure the stereoscopic luminous effect, the height of the light emitting portion 61 beyond the highest point of the mapping surface 51 is H, H>2mm, H does not exceed the distance between the mapping surface 51 and the mask 30, and the specific value of H can be selected according to the actual design.
[0045] Furthermore, the reflective surface of the reflector 70 is provided with a light distribution pattern (not shown in the figure); the reflector 70 is made of diffuse reflection material. The reflective surface of the reflector 70 is provided with a light distribution pattern, so that the light can be more evenly distributed during the reflection process. At the same time, the reflector 70 is made of diffuse reflection material, so that the light can be diffused in a more natural way during the reflection process, further enhancing the light output effect.
[0046] In order to improve the three-dimensional luminous effect, the light-transmitting member 60 is made of diffuse reflection material (diffuse material), so that the light has a better optical effect after passing through the light-transmitting member 60, meeting the design requirements.
[0047] In order to ensure the mapping effect of the mapping surface 51, the outer surface of the mapping part 50 is subjected to a high-gloss treatment, such as high-gloss injection molding technology, so that the mapping surface 51 has a very high smoothness to ensure the surface quality of the product; or the surface roughness of the workpiece is reduced by mechanical, chemical or electrochemical effects to obtain a bright and smooth surface.
[0048] Specifically, the light-transmitting member 60 includes a light-transmitting plate and a light-emitting portion 61 protruding from the light-transmitting plate and facing the outer surface of the mapping member 50 . The light-transmitting plate and the light-emitting portion 61 are integrally injection-molded.
[0049] Reference Figures 4 to 7Specifically, the light source assembly 40 and the reflector 70 are connected to the mapping member 50 in sequence, and the mapping member 50 is connected to the bottom shell 20. The light source assembly 40 includes a circuit board 41 provided with a light source, and a driving board 42 electrically connected to the circuit board 41 and used to drive the circuit board 41. The circuit board 41 and the driving board 42 are both connected to the reflector 70. The reflector 70 is formed with a guide structure, and the guide structure corresponds to the light source and is used to guide the light generated by the light source assembly 40 to the light-transmitting member 60.
[0050] Combination Figure 2 and Figure 3 In a specific application, the light generated by the light source assembly 40 is transmitted to the light-transmitting member 60 through the guiding structure, so that the light can be irradiated onto the mapping member 50 in a preset direction and range. At the same time, the light emitted by the light-emitting portion 61 and the light partially mapped onto the mapping surface 51 together form a luminous group to achieve a three-dimensional luminous effect. The mapping member 50 maps the light irradiated thereon to the corresponding position to achieve a three-dimensional luminous effect. The user can clearly see the content on the mapping member 50. In addition, the circuit board 41 and the driving board 42 are electrically connected to realize the function of controlling and driving the light source assembly 40. The reflective member 70 controls the guidance of the light by forming a guiding structure, so that the light can be irradiated onto the light-transmitting member 60 in a preset direction and range. The bottom shell 20 serves as a supporting structure for the entire assembly, making the entire assembly more stable and reliable.
[0051] In one embodiment, the guide structure is designed in the form of a guide channel. This guide channel has a curved section toward the light source, which plays a role in guiding light and enhancing the lighting effect. The entire reflector 70 can be regarded as an optical lens, which can disperse the light from the light source and guide it to a specific direction.
[0052] In another embodiment, the guide structure is in other forms that play a guiding role.
[0053] Specifically, the mapping member 50 and the light-transmitting member 60 are integrally molded as an insert, forming a first optical element, the reflecting member 70 is a second optical element, the first optical element and the second optical element are fixed together to form an optical assembly, the circuit board 41 is connected to the optical assembly, the driving board 42 is connected to the optical assembly, and then the whole is installed on the bottom shell 20, the mask 30 and the bottom shell 20 are covered and fixed, the driving board 42 is provided with an adapter harness, the adapter harness connects the driving board 42 and the circuit board 41, the bottom shell 20 is integrated with an assembly harness, the assembly harness is connected to the driving board 42, the light source uses LED lamp beads, the driving board 42 can control the display of the light source of the circuit board 41, and achieve different lighting effects; the device has a simple structure, a small size, and a light weight. When the power is turned on, the current is transmitted to the driving board 42 through the assembly wiring harness. The driving board 42 controls the LED lamp beads of the circuit board 41 to convert the electrical signal into light. The reflector 70 disperses the light and evenly guides it to the second optical element. The second optical element reflects the light onto the mask 30, and the mask 30 projects the light onto the target.
