[0047] The core of the utility model is to disclose an optical light-guiding structure to improve the adaptability of the vehicle lamp to the layout in a narrow space, while preventing the lamp beads from being directly exposed.
[0048] Another core of the utility model is to disclose a vehicle lamp including the above optical light guiding structure.
[0049] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions of the utility model described in the claims. It should be noted that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings. In the absence of conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.
[0050] Combination Figure 1-Figure 12The optical light guide structure 100 disclosed in the embodiment of the utility model includes a first channel 110 and a second channel 120. The first end of the first channel 110 is used to set a light unit 200 such as a light board and serves as a light input end of the optical light guide structure 100. The first end of the second channel 120 is connected to the second end of the first channel 110, and the second end is used to set a light output component 300 and serves as a light output end of the optical light guide structure 100. The inner walls of the first channel 110 and the second channel 120 are both provided with a reflective coating so that the light emitted by the light unit 200 can be reflected from the light input end of the optical light guide structure 100 to the light output end for light output, and the axes of the first channel 110 and the second channel 120 do not coincide, that is, the light output end and the light input end of the optical light guide structure 100 cannot be straightly connected through the first channel 110 and the second channel 120, so that the light unit 200 and the light output component 300 are staggered to achieve the hiding of the light unit 200.
[0051] As the light emitting unit 200 emits light, the light is reflected in the first channel 110 and the second channel 120 and emitted from the light emitting end through the light emitting assembly 300. Multiple reflections of the light in the first channel 110 and the second channel 120 can improve the uniformity of the emitted light.
[0052] Compared with the prior art, the optical light-guiding structure 100 disclosed in the embodiment of the utility model can hide the light-emitting units 200 such as optical teeth, lamp beads and lamp panels, and improve the light-emitting effect. At the same time, the light-emitting end and the light-incoming end of the optical light-guiding structure 100 in the utility model, which is an overall long tubular shape, can be arranged more freely, which can adapt to the spatial layout requirements of different car lights, solves the problem that the internal space of current car lights is small and optical components cannot be arranged, and can realize modular design, providing more options for styling design.
[0053] The first channel 110 and the second channel 120 are both hollow structures. The reflective coating may be a high-brightness aluminum-plated layer with a reflectivity of more than 95%, so that the light emitted by the light-emitting unit 200 can be transmitted almost losslessly in the first channel 110 and the second channel 120. In addition, the reflective coating may also be a chrome-plated coating, a glass bead coating, a polymer reflective coating, a metal oxide coating, etc.
[0054] Specifically, the axes of the first channel 110 and the second channel 120 do not overlap, including two situations. One is that the axes of the first channel 110 and the second channel 120 have an angle, that is, the first channel 110 and the second channel 120 are arranged at an angle to achieve the hiding of the light-emitting unit 200. The other is that the axes of the first channel 110 and the second channel 120 are parallel, but the two do not overlap. Fig.10In this case, the staggered arrangement of the axes of the first channel 110 and the second channel 120 can be achieved by connecting the intermediate channel 130 disposed between the first channel 110 and the second channel 120 .
[0055] Combination Figure 1 In one embodiment, an intermediate channel 130 is provided between the first channel 110 and the second channel 120, and a reflective coating is provided on the inner wall of the intermediate channel 130 to realize light reflection. The axis of the intermediate channel 130 has an angle with the axes of the first channel 110 and the second channel 120. The setting of the intermediate channel 130 enables the optical light-guiding structure 100 to further adapt to various narrow space layouts of vehicle lamps, conveniently avoid other structures inside the lamp, and make the position setting of the light-emitting unit 200 and the light-emitting component 300 more free.
[0056] Specifically, according to actual conditions, the number of the above-mentioned intermediate channels 130 can be one or more. When there are multiple intermediate channels 130, the multiple intermediate channels 130 are connected and communicated in sequence, the axes of two adjacent intermediate channels 130 have an angle, and the two intermediate channels 130 located at the ends are respectively communicated and connected with the first channel 110 and the second channel 120.
[0057] It can be understood that the optical light-guiding structure 100 disclosed in the present invention has a high degree of freedom in its bending arrangement. In some embodiments, by setting the angle between at least two intermediate channels 130, the coincidence of the axes of the first channel 110 and the second channel 120 can be achieved. When the number of intermediate channels 130 is not less than three, there is also a situation where the axis of a certain intermediate channel 130 is parallel to or coincides with the axis of the first channel 110 and / or the second channel 120, which will not be elaborated here.
[0058] Furthermore, the axes of the first channel 110 and the second channel 120 may be in the same plane or in different planes. Figure 1-Figure 12 , the axes of the first channel 110, the second channel 120 and the middle channel 130 shown in the figure are all in the same plane; when the axes of the first channel 110 and the second channel 120 are in different planes, the three-dimensional spatial layout of the optical light-guiding structure 100 can be achieved.
[0059] In one embodiment, in combination Figure 4The first channel 110 includes a first upper cover plate 112 and a first lower cover plate 111, the first upper cover plate 112 and the second lower cover plate 121 are connected, and the inner walls (surfaces facing each other) are provided with a reflective coating; the second channel 120 includes a second upper cover plate 122 and a second lower cover plate 121, the second upper cover plate 122 and the second lower cover plate 121 are connected, and the inner walls are provided with a reflective coating. This split structure facilitates the installation of the light-emitting unit 200 and the light-emitting component 300 with the optical light-guiding structure 100.
[0060] Correspondingly, the middle channel 130 can also be set as a split structure similar to the first channel 110 and the second channel 120. Specifically, the middle channel 130 includes a third upper cover plate 132 and a third lower cover plate 131. The third upper cover plate 132 and the third lower cover plate 131 are connected, and the inner walls are provided with a reflective coating.
[0061] Furthermore, the first upper cover plate 112 and the second upper cover plate 122 can be set as an integrated structure, and the first lower cover plate 111 and the second lower cover plate 121 can be set as an integrated structure, which is convenient for preparation by an integrated molding method. When the optical light guide structure 100 includes the middle channel 130, the third upper cover plate 132, the first upper cover plate 112 and the second upper cover plate 122 can be set as an integrated structure, and the third lower cover plate 131, the first lower cover plate 111 and the second lower cover plate 121 can be set as an integrated structure.
[0062] In order to realize the connection between the first upper cover plate 112 and the first lower cover plate 111, the Figure 4 A first mounting platform is provided on both sides of the first lower cover plate 111 in the extension direction, a first positioning protrusion is provided on the first mounting platform, a first positioning plate for fitting with the first mounting platform is provided on both sides of the first upper cover plate 112 in the extension direction, and a first positioning groove for the first positioning protrusion to be embedded is provided on the first positioning plate.
[0063] In order to achieve the connection between the second upper cover plate 122 and the second lower cover plate 121, second mounting platforms are provided on both sides of the extension direction of the second lower cover plate 121, and second positioning protrusions are provided on the second mounting platforms, and second positioning plates for fitting with the second mounting platforms are provided on both sides of the extension direction of the second upper cover plate 122, and second positioning grooves for the second positioning protrusions to be embedded are provided on the second positioning plates.
[0064] Furthermore, the first mounting platform is provided with a first positioning groove, and the first positioning plate is used to be embedded in the first positioning groove to achieve positioning. The second mounting platform is provided with a second positioning groove, and the second positioning plate is used to be embedded in the second positioning groove to achieve positioning.
[0065] In addition, the first upper cover plate 112 and the first lower cover plate 111, the second upper cover plate 122 and the second lower cover plate 121 can also be connected by means of snap connection, screw connection, bonding, etc. or a combination of these means. The connection method between the third upper cover plate 132 and the third lower cover plate 131 is similar to the connection method between the first upper cover plate 112 and the first lower cover plate 111, and will not be described in detail here.
[0066] Combination Figure 5-Figure 7 In the above embodiment, the first end of the first channel 110 is provided with a first mounting slot for embedding the light emitting unit 200; the light emitting assembly 300 includes a light-transmitting cover, and the second end of the second channel 120 is provided with a second mounting slot for embedding the light-transmitting cover. The split structure of the first channel 110 and the second channel 120 facilitates the installation and embedding of the light emitting unit 200 and the light emitting assembly 300 in the first mounting slot and the second mounting slot, respectively.
[0067] Combination Figure 8 and Fig. 9 The light-transmitting cover can be of various shapes and structures, and optical patterns that can disperse the light and achieve uniform light output can be provided on the light-emitting surface and the light-incoming surface of the light-transmitting cover.
[0068] In addition, the first channel 110 and the second channel 120 (and the middle channel 130) can be integrally configured as an integrated structure. For example, the optical light-guiding structure 100 can be integrally configured as a curved pipe structure, and a reflective coating can be coated on the inner wall of the pipe structure.
[0069] For the above-mentioned integrated optical light guide structure 100, in order to facilitate the fixing of the light emitting unit 200 and the light emitting assembly 300 on the optical light guide structure 100, a first mounting plate can be provided at the light input end of the optical light guide structure 100, and the light emitting unit 200 can be mounted on the first mounting plate by screws. A second mounting plate is provided at the light output end of the optical light guide structure 100, and the light emitting assembly 300 can be mounted on the second mounting plate by screws.
[0070] In order to ensure the utilization rate of light, a reflector can be set at the first end of the first channel 110. When the light-emitting unit 200 is installed on the first channel 110, the light-emitting part (such as lamp beads) of the light-emitting unit 200 is located in the reflector. The reflector can reflect the light emitted by the light-emitting part away from the first channel 110 toward the direction of the first channel 110, thereby improving the light-emitting effect.
[0071] This long channel form allows for a higher degree of freedom in placement of the light-emitting unit 200 and can adapt to a variety of space layouts. At the same time, the light-emitting position can be flexibly set according to modeling requirements, with a higher degree of freedom.
[0072] The vehicle lamp disclosed in the present invention includes the above-mentioned optical light-guiding structure 100, so it also has the above-mentioned beneficial effects. Other structures refer to the prior art and will not be described in detail here.
[0073] Furthermore, this optical light-guiding structure 100 supports multiple arrangements and combinations in various forms; supports horizontal placement or vertical placement, with flexible and diverse angle selection; supports various forms of light-emitting end lens settings, with diverse choices; supports various shapes of bending and avoidance, and is space-friendly.
[0074] For example, combined with Fig.11 and Fig.12 The optical light guide structure 100 can be a plurality of flat or stacked structures, and each optical light guide structure 100 is provided with a light emitting unit 200 and a light emitting component 300 in a one-to-one correspondence to form a plurality of light emitting modules. The plurality of light emitting modules can form a variety of shapes, and the light output of the light emitting unit 200 of each light emitting module is controlled by a circuit, so as to achieve a plurality of combined lighting effects such as sequential lighting, flowing lighting, light show, and programmed lighting, which has a lower cost than directly producing complex-shaped car lights.
[0075] Combination Fig.11 and Fig.12 When the light-emitting modules are arranged in a plurality, the light-emitting ends of each optical light-guiding structure 100 can be arranged on the same plane to facilitate the arrangement of the heat dissipation device.
[0076] For example, the heat dissipation device can be an air-cooled heat dissipation device, including a fan and an air outlet duct. The air outlet of the fan is connected to the air outlet duct. A plurality of air guide outlets for air outlet are arranged at intervals on the side wall of the air outlet duct. Each air guide outlet corresponds one-to-one to the light incident end position of each optical light guide structure 100, and can effectively achieve heat dissipation for each light-emitting unit 200.
[0077] The above-mentioned heat dissipation device can also be a liquid cooling heat dissipation device, which will not be described in detail here.
