DETAILED DESCRIPTION
[0024] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.
[0025] like Figures 1 to 6 As shown, the vehicle lamp light guide plate and diffuser plate combined structure, the diffuser plate 2 is arranged on one side of the light guide plate 1, the other side of the light guide plate 1 is provided with a mounting plate 3, the light guide plate 1 includes a light guide strip 4, the light guide strip 4 is fixedly connected to the end of the light guide plate 1, the mounting plate 3 is provided with a position light 5, and the position light 5 is located at the ends of the light guide plate 1 and the light guide strip 4.
[0026] The diffuser plate 2 is used to evenly diffuse the light from the light guide plate 1, transforming the light into a softer effect. At the same time, it can blur the effect of the components located on the inner side of the diffuser plate 2 to meet the appearance requirements of the car lights. For the light-evening effect area of the lamp, one part uses the light guide strip 4 + diffuser plate 2 to achieve the light-evening effect, and the other part uses the diffuser plate 2 + light guide plate 1 to achieve the light-evening effect; the light guide plate 1 realizes the transmission of light inside the light guide plate 1 by designing micro-structure patterns such as grooves, dots, and light guide teeth 7. This part is suitable for wider and larger area styling requirements; through the combination of the above two structures, the luminous uniformity requirements of irregular light-evening areas are effectively solved.
[0027] There are multiple position lights 5, and all are located at the ends of the side light guide plate 1 and the light guide strip 4 and at the side ends of the headlight, so as to achieve the effect that the light is incident from the side and emitted vertically from the light guide plate 1 and the light guide strip 4. It is suitable for installation in the use environment where the internal structure space of the headlight is limited, and provides more space for the design of other components. At the same time, it replaces the current direct light source design scheme, which is conducive to reducing the cost of using lamp beads and meeting the user's demand for the diversity of headlights.
[0028] like Figure 1 and Figure 2-1As shown, the diffuser plate 2 is evenly distributed with light-distributing patterns 6, and the light-guiding teeth 7 are evenly spaced on the light-guiding strip 4. The light-distributing patterns 6 are used to make the light transmitted and reflected inside the light-guiding plate 1 and then emitted from the light-guiding plate 1, so as to achieve a uniform lighting effect. The light-guiding strip 4 is designed with light-guiding teeth 7 to achieve light transmission inside the light-guiding strip 4, so that each part of the light-guiding strip 4 emits light evenly, which can be applied to the shape requirements of thin and narrow strips.
[0029] like Figure 6 As shown, the light-distributing pattern 6 is an arc-shaped concave structure. The light-distributing pattern 6 is arranged regularly, and the curvatures of the two sides of the light-distributing pattern 6 are different. The curvature at the incident end is smaller, which is conducive to expanding the light reflection range, and can also make the light multiple times emitted inside the light guide plate 1, thereby improving the brightness uniformity; the light guide plate 1 located on one side of the inclined structure is also provided with reflective teeth 16, which are evenly distributed, so that the outgoing light is refracted into the interior of the lamp, avoiding strong bright spots at the end, and achieving a uniform effect. By designing a reasonable light-distributing pattern 6, various forms of lighting shapes can be realized under the premise of satisfying the light-distributing effect, thereby meeting the lighting needs of customers; the light-distributing pattern 6 arranged regularly can not only improve the light uniformity, but also facilitate processing and reduce manufacturing costs.
[0030] like Figure 2-1 and Figure 2-2 As shown, one side of the light guide plate 1 is an inclined structure, and the other side is a stepped structure. The above-mentioned inclined structure is designed for the light guide plate 1 to meet the appearance of the automobile lamp. In order to ensure that the light guide plate effect is more uniform and the light transmission stroke is as consistent as possible, the other side of the light guide plate 1 is designed as a stepped structure, and the position lamp 5 is installed on the stepped part, which not only facilitates the installation of the position lamp 5, but also reduces the number of uniform patterns on the upper part of the light guide plate 1, so that the overall brightness of the light guide plate 1 tends to be consistent, thereby ensuring uniform lighting.
[0031] like Figure 4-1 and Figure 4-2 As shown, a positioning block 8 is provided at the end of the light guide plate 1, a positioning hole 9 is provided on the mounting plate 3, and the positioning block 8 extends from the positioning hole 9; positioning notches 10 are provided on both sides of the mounting plate 3. The positioning hole 9 and the positioning notch 10 are both rectangular structures, which are conducive to preventing the mounting plate 3 from rotating relative to each other. After the positioning block 8 is installed with the positioning hole 9 and the positioning notch 10 is installed with the lamp mounting point, the overall stability of the mounting plate 3 can be improved, thereby stabilizing the installation position of the position lamp 5 to achieve a stable light output effect.
[0032] like Figure 4-1 , Figure 4-2 and Figure 6 As shown, the positioning hole 9 is square and the positioning block 8 is trapezoidal. The square positioning hole 9 can reduce the rotation of the mounting plate 3 and improve the stability of the mounting plate 3. The positioning block 8 with a trapezoidal structure can reduce the friction between it and the positioning hole 9, facilitating the positioning and installation process of the mounting plate 3.
[0033] like Figure 3 As shown, a first connecting plate 11 is provided at the bottom of the light guide plate 1, a second connecting plate 12 and a third connecting plate 13 are provided on both sides of the diffuser plate 2, a fourth connecting plate 14 is provided at the upper end of the diffuser plate 2, and the fourth connecting plates 14 are provided in pairs; a fifth connecting plate 15 is provided at the bottom of one end of the diffuser plate 2. The middle of the above connecting plates are provided with connecting holes for stably mounting the light guide bar 4 and the diffuser plate 2 on the vehicle lamp structure. The fourth connecting plates 14 provided in pairs can improve the installation stability of the diffuser plate 2.
[0034] like Figure 2-1 and Figure 2-2 As shown, the diffuser plate 2 is matched with the light guide plate 1, and the light guide bar 4 is in an arc-shaped structure. The above structure is used to ensure that the light emitted from the light guide plate 1 and the light guide bar 4 can completely pass through the diffuser plate 2, making the overall light softer and avoiding local over-brightness or over-darkness. The arc-shaped light guide bar 4 is used to ensure that all parts of the light guide bar 4 can be transmitted with light to avoid local dark spots.
[0035] like Figure 4-2 As shown, a wiring port 17 is provided at the end of the mounting plate 3. The wiring port 17 is used to provide power to the position lamp 5. The wiring port 17 is located at the upper end of the mounting plate 3, which is convenient for plugging with a wiring.
[0036] The combined structure of the light guide plate and the diffuser plate of the vehicle lamp meets the lighting requirements of narrow or large areas through the structural design of the diffuser plate 2, the light guide bar 4 and the light guide plate 1, and realizes the light-distributing effect of irregular shapes, which can effectively meet the customer's needs for the light-distributing effect of the special-shaped position lamp 5 and the diversity of light shapes; the light-distributing pattern 6 and the light guide teeth 7 with reasonable structures are also designed to improve the uniformity of the light output. This structure replaces the traditional LED direct light-emitting solution, reduces the use of lamp beads, has a simple structure, greatly saves the labor hours of the light source board manufacturing process and effectively reduces the cost.
[0037] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
