[0001] The utility model relates to the technical field of automobile head and tail lights, in particular to an automobile head and tail light with an ultra-wide lighting function. Background Technique

[0002] With the popularization of automobile transportation tools, the number of automobiles owned by people is gradually increasing, and the application of automobile LED lamps is also increasing. Due to its many advantages such as energy saving and long service life, people are more and more fond of LED car lights.

[0003] At present, most of the combination forms of light guides and thick walls on the market are the combination of single light guides and multiple thick walls. This structure has the problem of uneven light emission, especially at the joint between the light guide and the thick wall part. At the same time, this structure increases the complexity and manufacturing cost of the car lights. At the same time, it is difficult to achieve a too wide light guide, which may cause accidents because other vehicles cannot observe the car tail light signal in time. Summary of the Invention

[0004] The purpose of the utility model is to provide an automobile head and tail light with an ultra-wide lighting function to solve the problems raised in the above background technique.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] An automobile head and tail light with an ultra-wide lighting function includes a first LED lamp, a second LED lamp, a special-shaped light guide, a gradient light guide, and a thick-wall light guide. The first LED lamp is fixedly connected to the gradient light guide, the second LED lamp is fixedly connected to the special-shaped light guide, the gradient light guide is connected to the thick-wall light guide, and the special-shaped light guide is connected to the thick-wall light guide.

[0007] The first LED lamp and the second LED lamp are used as the main light-emitting devices for emitting the light required for illuminating the automobile head and tail lights. The special-shaped light guide and the gradient light guide are used as light transmission devices to uniformly diffuse the light emitted by the first LED lamp and the second LED lamp in the Z direction, achieving the maximum range of light diffusion, and then passing through the thick-wall light guide to perform Z-direction diffusion again and then emitting it to the outside to illuminate the outside.

[0008] Further, the special-shaped light guide is provided with a special-shaped installation cavity, the second LED lamp is placed in the special-shaped installation cavity, one end of the special-shaped light guide close to the second LED lamp is arc-shaped, one end of the special-shaped light guide close to the thick-wall light guide is a cuboid light guide structure, and one side of the special-shaped light guide close to the thick-wall light guide is provided with special-shaped patterns, and the special-shaped patterns are horizontal stripes.

[0009] The special-shaped mounting cavity serves as the main mounting base for installing the second LED lamp. One end of the special-shaped light guide near the second LED lamp is arc-shaped, which reduces the influence of the light guide effect on the light propagation path. The light emitted by the second LED lamp is evenly diffused in the Z direction through the special-shaped pattern, and then the light is emitted onto the thick-walled light guide.

[0010] Furthermore, the gradient light guide is provided with a gradient mounting cavity. The first LED lamp is placed in the gradient mounting cavity. One end of the gradient light guide connected to the first LED lamp is circular, and the other end is rectangular. One side of the gradient light guide close to the thick-walled light guide is provided with gradient patterns, and the gradient patterns are horizontal strips.

[0011] The gradient mounting cavity serves as the main mounting base for installing the first LED lamp. The circular end of the gradient light guide is to better receive the light emitted by the first LED lamp. The circular shape gradually changing to a rectangular shape is to increase the light diffusion range during the light conduction process, and make the light diffuse wider in the Z direction through the gradient patterns.

[0012] Furthermore, the thick-walled light guide is provided with thick-walled patterns on both the inner and outer sides of the thick-walled light guide, and the thick-walled patterns are square.

[0013] Through the thick-walled patterns on both the inner and outer sides, the light emitted by the special-shaped light guide and the gradient light guide after diffusion is diffused again, realizing an increase in the Z-direction diffusion range of the light.

[0014] Furthermore, the special-shaped light guide is located above the gradient light guide.

[0015] The special-shaped light guide is shorter than the gradient light guide and is installed above the gradient light guide, realizing a narrower upper part and a wider lower part, bringing a unique design sense to the car taillight, and at the same time making the taillight more eye-catching when it lights up.

[0016] Furthermore, the position of the special-shaped pattern on the special-shaped light guide is made of a transparent material.

[0017] The material at the position of the special-shaped pattern is a transparent material, which is beneficial to the propagation and diffusion of light, and minimizes the loss of light propagation to the greatest extent.

[0018] Furthermore, the position of the gradient pattern on the gradient light guide is made of a transparent material.

[0019] The material at the position of the gradient pattern is a transparent material, which is beneficial to the propagation and diffusion of light, and minimizes the loss of light propagation to the greatest extent.

[0020] Furthermore, the position of the thick-walled pattern on the thick-walled light guide is made of a transparent material.

[0021] The material at the position of the thick-walled pattern is a transparent material, which is beneficial to the propagation and diffusion of light, and minimizes the loss of light propagation to the greatest extent.

[0022] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows: The first LED lamp and the second LED lamp of the present utility model emit light, which respectively propagate on the gradient light guide and the special-shaped light guide. The first LED lamp outputs light to the inside of the gradient light guide through the circular end of the gradient light guide, and diffuses in the Z direction on the side of the gradient light guide provided with gradient patterns, realizing an increase in the Z-direction diffusion width of the light. The light emitted by the second LED lamp diffuses in the Z direction through the side of the special-shaped light guide provided with special-shaped patterns, increasing the diffusion of light in the Z direction. The light diffused through the gradient patterns and the special-shaped patterns is diffused again through the thick-wall patterns, increasing the Z-direction diffusion degree of the light.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] The present utility model provides the following technical solutions:

[0032] As Figure 1As shown in the figure, an automotive head and tail lamp with an ultra-wide lighting function includes a first LED lamp 1, a second LED lamp 2, a special-shaped light guide 3, a gradient light guide 4, and a thick-wall light guide 5. The first LED lamp 1 is fixedly connected to the gradient light guide 4, the second LED lamp 2 is fixedly connected to the special-shaped light guide 3, the gradient light guide 4 is connected to the thick-wall light guide 5, and the special-shaped light guide 3 is connected to the thick-wall light guide 5.

[0033] The first LED lamp 1 and the second LED lamp 2 serve as the main light-emitting devices for emitting the light required for automotive head and tail lamp illumination. The special-shaped light guide 3 and the gradient light guide 4 serve as light transmission devices to uniformly diffuse the light emitted by the first LED lamp 1 and the second LED lamp 2 in the Z direction, achieving the maximum range of light diffusion. Then, the light is diffusely emitted to the outside through the thick-wall light guide 5 again after another Z-direction diffusion for external illumination.

[0034] As Figure 2 shown in the figure, the special-shaped light guide 3 is provided with a special-shaped installation cavity. The second LED lamp 2 is placed in the special-shaped installation cavity. One end of the special-shaped light guide 3 close to the second LED lamp 2 is arc-shaped, and one end of the special-shaped light guide 3 close to the thick-wall light guide 5 is a cuboid light guide structure. One side of the special-shaped light guide 3 close to the thick-wall light guide 5 is provided with special-shaped patterns 31, and the special-shaped patterns 31 are horizontal stripes.

[0035] The special-shaped installation cavity serves as the main installation base for installing the second LED lamp 2. The arc-shaped end of the special-shaped light guide 3 close to the second LED lamp 2 reduces the influence of the light guide effect on the light propagation path. The light emitted by the second LED lamp 2 is uniformly diffused in the Z direction through the special-shaped patterns 31 and then emitted onto the thick-wall light guide 5.

[0036] As Figure 3 shown in the figure, the gradient light guide 4 is provided with a gradient installation cavity. The first LED lamp 1 is placed in the gradient installation cavity. One end of the gradient light guide 4 connected to the first LED lamp 1 is circular, and the other end of the gradient light guide 4 is rectangular. One side of the gradient light guide 4 close to the thick-wall light guide 5 is provided with gradient patterns 41, and the gradient patterns 41 are horizontal stripes.

[0037] The gradient installation cavity serves as the main installation base for installing the first LED lamp 1. The circular end of the gradient light guide 4 is for better receiving the light emitted by the first LED lamp 1. The circular shape gradually changing to a rectangular shape is to increase the light diffusion range during the light conduction process, allowing the light to be diffusely spread wider in the Z direction through the gradient patterns 41.

[0038] As Figure 4 and Figure 5 shown in the figure, the thick-wall light guide 5 is provided with thick-wall patterns 51 on both the inner and outer sides of the thick-wall light guide 5, and the thick-wall patterns 51 are square.

[0039] Through the thick-wall patterns 51 on both the inner and outer sides, the light emitted by the diffused special-shaped optical waveguide 3 and the gradient optical waveguide 4 is diffused again, achieving an increase in the Z-direction diffusion range of the light.

[0040] As Figure 1 shown, the special-shaped optical waveguide 3 is located above the gradient optical waveguide 4.

[0041] The special-shaped optical waveguide 3 is shorter than the gradient optical waveguide 4 and is installed above the gradient optical waveguide 4, achieving a narrower upper part and wider lower part, bringing a unique design sense to the car taillight and making the taillight more eye-catching when it lights up.

[0042] As Figure 2 shown, the position of the special-shaped pattern 31 on the special-shaped optical waveguide 3 is made of a transparent material.

[0043] The material at the position of the special-shaped pattern 31 is a transparent material, which is beneficial to the transmission and diffusion of light, minimizing the loss of light transmission to the greatest extent.

[0044] As Figure 3 shown, the position of the gradient pattern 41 on the gradient optical waveguide 4 is made of a transparent material.

[0045] The material at the position of the gradient pattern 41 is a transparent material, which is beneficial to the transmission and diffusion of light, minimizing the loss of light transmission to the greatest extent.

[0046] As Figure 4 and Figure 5 shown, the position of the thick-wall pattern 51 on the thick-wall optical waveguide 5 is made of a transparent material.

[0047] The material at the position of the thick-wall pattern 51 is a transparent material, which is beneficial to the transmission and diffusion of light, minimizing the loss of light transmission to the greatest extent.

[0048] The working principle of the present utility model:

[0049] The first LED lamp 1 and the second LED lamp 2 emit light, which are respectively transmitted on the gradient optical waveguide 4 and the special-shaped optical waveguide 3. The first LED lamp 1 outputs light to the inside of the gradient optical waveguide 4 through the circular end of the gradient optical waveguide 4, and performs Z-direction diffusion on the side of the gradient optical waveguide 4 provided with the gradient pattern 41, achieving an increase in the Z-direction diffusion width of the light. The light emitted by the second LED lamp 2 is diffused in the Z direction through the side of the special-shaped optical waveguide 3 provided with the special-shaped pattern 31, increasing the diffusion of light in the Z direction. The light diffused through the gradient pattern 41 and the special-shaped pattern 31 is diffused again through the thick-wall pattern 51, increasing the Z-direction diffusion degree of the light.
