Specific embodiments
[0048] The core of the present utility model lies in disclosing a vehicle lamp to achieve an efficient light-emitting solution for ultra-narrow signal lamps.
[0049] Another core of the present utility model lies in disclosing a vehicle including the above vehicle lamp.
[0050] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not impose any limitation on the content of the utility model described in the claims. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model described in the claims. It should be noted that for the sake of description, only the parts related to the relevant utility model are shown in the drawings. Without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.
[0051] Combined with Figures 1-16 , the vehicle lamp disclosed in the present utility model includes a lamp board 600, a collimator 500, a glass optical fiber 400, and a bracket assembly. A plurality of lamp beads 610 are arranged at intervals on the lamp board 600; there are a plurality of collimators 500, and the light incident ends of each collimator 500 correspond to each lamp bead 610 one by one; there are a plurality of glass optical fibers 400, and each glass optical fiber 400 is correspondingly arranged at the light output end of each collimator 500; the bracket assembly is provided with a plurality of extrusion grooves, the extrusion grooves extend along the light output direction of the lamp beads 610, and the cross section gradually changes from circular to rectangular, and each glass optical fiber 400 is correspondingly arranged in each extrusion groove and is deformed by the extrusion groove to be adapted to the shape of the extrusion groove, that is, the cross section of the light incident end (light incident end 410 of the optical fiber) of the glass optical fiber 400 is circular and adapted to the collimator 500, and the cross section of the light output end (light output end 420 of the optical fiber) of the glass optical fiber 400 is extruded into a rectangle. Exemplarily, the light output end of the glass optical fiber 400 is usually rectangular to achieve an ultra-narrow light output solution.
[0052] Combined with Figure 17 AndFigure 18 , the glass optical fiber 400 includes a protective jacket layer 401 and a plurality of single fiber cores 402. The single fiber cores 402 are arranged within the protective jacket layer 401. The protective jacket layer 401 made of flexible plastic material has the characteristic of a variable cross-section under pressure, and by physically squeezing the protective jacket layer 401, the single fiber cores 402 within the protective jacket layer 401 can be driven to adjust their positions without damaging the total internal reflection characteristics of the single fiber cores 402. During assembly, by installing the glass optical fiber 400 into the extrusion groove, the light-emitting end cross-section of the glass optical fiber 400 can be extruded into a rectangle. When the lamp bead 610 emits light, the light enters the glass optical fiber 400 after being collimated by each collimator 500 and finally exits from the light-emitting end of the glass optical fiber 400.
[0053] Compared with the prior art, the present utility model uses a special-shaped glass optical fiber 400 with a rectangular cross-section at the light-emitting end for light emission. Due to total internal reflection inside the glass optical fiber 400, the light loss is small, which can meet the optical requirements of high-performance signal lamps with an optical opening of 3 mm to 4 mm. The present utility model can achieve the effect of a large-sized light-incident end and a narrow and long light-emitting end. Keeping the light-incident end large-sized can improve the optical coupling efficiency of the glass optical fiber 400, enabling the light to still be efficiently conducted after the shape of the light-emitting end changes. The light-emitting end being narrow and long can increase the spacing of the lamp beads 610, reducing the number of light sources while ensuring high luminous efficiency to the greatest extent. The present utility model avoids the conventional optical thick-wall structure, which can reduce the product weight and system power, and lower the design cost and product cost. The present utility model realizes an ultra-narrow signal design scheme, which is easy to integrate with the vehicle body and serves the function of hiding the signal lamp. Additionally, by utilizing the flexible and high-luminous-efficiency characteristics of the glass optical fiber 400, the lamp beads 610 can be easily co-mounted on the same board. Compared with the traditional scheme that can only use the methods of detaching the board and using flexible boards, the cost can be effectively reduced.
[0054] It should be noted that the light-emitting end of the glass optical fiber 400 needs to be plastically deformed by the extrusion groove, while the light-incident end of the glass optical fiber 400 does not require plastic deformation by the extrusion groove. Therefore, the light-emitting end of the glass optical fiber 400 needs to be located within the extrusion groove, and the light-incident end of the glass optical fiber 400 can extend outside the extrusion groove.
[0055] Specifically, the light-incident end of the glass optical fiber 400 and the light-emitting end of the collimator 500 are adhesively connected by optical curing glue. The present utility model can standardize the components of the glass optical fiber 400 and the collimator 500, enabling different projects to share parts, with low cost. It only needs to change the number and positional relationship of the extrusion grooves of the bracket components for different shapes, effectively simplifying the design process, and having a compact structure, small product volume, short design cycle, and low product cost.
[0056] In addition, to further improve the luminous efficiency, the vehicle lamp further includes a plurality of condenser lenses, and each condenser lens is correspondingly arranged between the lamp bead 610 and the collimator 500 to improve the light-emitting efficiency of each lamp bead 610.
[0057] Combined with Figures 5-14 , the bracket assembly includes a first bracket 200 and a second bracket 210. The first bracket 200 is provided with a first extrusion semi-groove 202; the second bracket 210 is provided with a second extrusion semi-groove 212. Both the first extrusion semi-groove 202 and the second extrusion semi-groove 212 extend along the light-emitting direction of the lamp bead 610, and the cross-section of each gradually changes from a semicircle to a rectangle. After assembly, the first extrusion semi-groove 202 and the second extrusion semi-groove 212 face each other and form the above-mentioned extrusion groove. The split structure of the bracket assembly facilitates the assembly of the glass optical fiber 400 in the extrusion groove.
[0058] Furthermore, combined with Figure 1 and Figure 3 , the lamp board 600 is arranged in the lamp housing 100. The lamp housing 100 has opposite first side plates and second side plates. The first bracket 200 is provided with a first clamping groove 201 that is clamped and matched with the first side plate, and the second bracket 210 is provided with a second clamping groove 211 that is clamped and matched with the second side plate.
[0059] Among them, the bracket assembly and the lamp housing 100 are adhesively connected or bolted with a two-component adhesive. The lamp board 600 and the lamp housing 100 are adhesively connected or bolted. To facilitate the positioning and installation of the lamp board 600 and the lamp housing 100, positioning protrusions are provided on the lamp housing 100, and positioning grooves for the positioning protrusions to be embedded are provided on the lamp board 600. The number of positioning protrusions is not limited to one, and the number of positioning grooves matches the number of positioning protrusions.
[0060] In addition, a light distribution lens 300 is provided at the light-emitting end of the glass optical fiber 400. The light distribution lens 300 is connected to the bracket assembly, and optical patterns are provided on the side of the light distribution lens 300 facing the glass optical fiber 400. The types of optical patterns are not limited to strip patterns and granular patterns, as long as light homogenization can be achieved.
[0061] To facilitate positioning and installation, a first installation card slot and a second installation card slot for clamping and positioning the light distribution lens 300 are respectively provided on the first bracket 200 and the second bracket 210.
[0062] The light distribution lens 300 and the bracket assembly are preferably connected by laser welding to ensure sealing and prevent water from entering the interior space of the vehicle lamp.
[0063] To facilitate the installation of the collimator 500, a plurality of installation slots for the collimator 500 to be embedded in one-to-one correspondence are provided on the bracket assembly.
[0064] The vehicle disclosed by the present utility model includes the above-mentioned vehicle lamp, so it also has the above-mentioned structure and beneficial effects. Other structures refer to the prior art and will not be elaborated here.
[0065] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
