[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making novel work are within the scope of protection of the utility model.

[0041] In the description of the present invention, it should be understood that the terms "upper", "lower", "top surface", "bottom surface" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the positions or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0042] The light guide structure disclosed in the utility model comprises a light guide, and the light guide comprises a light mixing part 100 and a diffusion part 101. The light mixing part 100 is cylindrical, and the diffusion part 101 is fan-shaped, and its light inlet end is connected with the light outlet end of the light mixing part 100. Specifically, the light guide is an integrated design, and the operator can change the shape of the light outlet end of the diffusion part 101 according to the use needs to achieve different lighting effects, that is, under the premise of ensuring the light mixing area, the shape after diffusion can be diversified, such as triangular, arc and other lighting effects can be achieved, thereby improving the lighting effect, expanding the lighting area, and thus improving the use flexibility of the light guide. Specifically, the material of the light guide includes but is not limited to transparent PC material, transparent PMMA material, etc. The light guide structure provided by the utility model is provided with a diffusion part 101, so that the shape of the light output by the light guide structure can be changed according to the shape of the fan-shaped diffusion part 101. The light achieves a uniform light effect in the light mixing part 100 and then enters the diffusion part 101 to achieve the expansion of the light type. When the thickness of the diffusion part 101 is uniform, the lighting effect of the light guide structure is a straight line, that is, the incoming light is a circle and the outgoing light is a straight line, which improves the lighting effect and expands the lighting area. It can achieve dot matrix lighting using only the light guide, thereby improving the flexibility of the light guide.

[0043] In order to optimize the above technical solution, the light guide structure also includes an LED light board 200, and the light input end of the light mixing part 100 is connected to the LED light board 200. Specifically, one or more LED light sources 201 are arranged on the LED light board 200, one LED light source 201 can cooperate with one light guide, and one LED light board 200 can light up one or more light guides at the same time, and the arrangement angles of the LED light board 200 and the LED light source 201 can be flexibly changed. When in use, the LED light source 201 is turned on, and the light enters from the light input end of the light mixing part 100 to achieve light mixing, and then enters the diffusion part 101 to achieve the expansion of the light type, thereby expanding the lighting area and improving the flexibility of the use of the light guide. It should be noted that in the prior art, if the lighting area of ​​the light needs to be changed, it needs to be achieved through specific optical teeth. The use of the above-mentioned light guide structure can achieve the effect of light diffusion in the material through the shape of the light guide itself, thereby improving the flexibility of the use of the light guide.

[0044] like Figure 2As shown, the light-emitting unit disclosed in the utility model includes a control power supply 203, a wiring harness 202 and the above-mentioned light-guiding structure. The number of the wiring harness 202 is adapted to the number of the light-guiding structure. The wiring harness 202 is used to connect the light-guiding structure and the control power supply 203. The control power supply 203 is used to control the light output of the light-guiding structure. Specifically, through the circuit control of the control power supply 203 and the wiring harness 202, the lighting of a single LED light panel 200 can be realized. At the same time, with the lighting of the fan-shaped light guide, a variety of lighting forms can be realized, including but not limited to sequential lighting, flowing lighting, light show, programmed lighting and other forms, thereby improving the flexibility of the use of the light guide. Specifically, by changing the number and arrangement of the light-guiding structure, such as horizontal placement, vertical placement, inclined placement (flexible and diverse angle selection), etc., the lighting shape of the light-emitting unit can be changed, thereby further expanding the scope of application of the light-emitting unit. When in use, the control power supply 203 controls the lighting and extinguishing of the light guide structure through the wiring harness 202, thereby realizing the lighting forms of alternating lighting, simultaneous lighting, partial lighting, etc. of the light emitting unit, thereby improving the flexibility of use of the light guide and the flexibility of use of the light emitting unit.

[0045] like Figure 3-Figure 6 As shown, the modular light-emitting module disclosed in the utility model includes a bracket 300, a cover plate 400 and the above-mentioned light-emitting unit, the bracket 300 is used to receive the light-guiding structure of the light-guiding unit, the cover plate 400 is connected to the bracket 300, and the first side of the cover plate 400 is a closed end, and the second side thereof is an open end, the closed end is arranged close to the light-mixing part 100 of the light-guiding structure, and the open end is arranged close to the diffusion part 101 of the light-guiding structure. Specifically, when the cover plate 400 is connected to the bracket 300, the cover plate 400 and the bracket 300 form a shape with five closed sides and one open side, wherein the closed end is arranged opposite to the open end, and the light-emitting end of the diffusion part 101 is arranged close to the open end so that light can be emitted through the open end. Furthermore, a folding part 304 is arranged on the side close to the bracket 300 and the cover plate 400 to further seal, thereby protecting the light guide and the LED light board 200, thereby extending the service life of the light guide structure. The modular light-emitting module provided by the utility model is arranged between the bracket 300 and the cover plate 400 when in use, and the light-emitting unit is arranged between the bracket 300 and the cover plate 400, and the light-emitting end of the diffusion part 101 is arranged close to the open end of the cover plate 400, that is, the light emitted by the light-emitting unit is emitted through the open end of the cover plate 400. By changing the shape of the bracket 300 and the cover plate 400, multiple light-emitting units can be integrated therein to form different light-emitting effects and realize a variety of lighting shapes, thereby improving the flexibility of the use of the light guide and expanding the scope of application of the modular light-emitting module.

[0046] In order to optimize the above technical solution, the bracket 300 is provided with two or more avoidance openings 301 for avoiding the wiring harness 202 of the light-emitting unit. The bracket 300 also includes a pillar 302, and the pillar 302 is used to support the light guide structure. Specifically, when connecting the wiring harness 202, it is necessary to wrap the wiring harness 202 around the side of the LED light board 200 close to the light guide, which will cause bending. By providing the avoidance opening 301 on the bracket 300, the wiring harness 202 can be avoided from being damaged, thereby increasing the service life of the wiring harness 202. Specifically, the pillar 302 is arranged perpendicular to the plane of the bracket 300. When in use, the light guide is arranged on the pillar 302 to improve the stability of the light guide so that it can be applied to a variety of application environments. By adjusting the height of the column, the relative position of the outgoing light of the light guide in the modular light-emitting module can be adjusted to meet a variety of lighting effects.

[0047] In order to optimize the above technical solution, the modular light-emitting module also includes a fixing buckle 303 and a bayonet 401. The fixing buckle 303 is arranged on one of the bracket 300 and the cover plate 400, and the bayonet 401 is arranged on the other of the bracket 300 and the cover plate 400. When the cover plate 400 is connected to the bracket 300, the fixing buckle 303 is engaged with the bayonet 401. Specifically, the fixing buckle 303 is connected to the folding portion 304. During use, when the cover plate 400 is connected to the bracket 300, the bayonet 401 is snapped into the inside of the fixing buckle 303, and the folding portion 304 of the bracket 300 and the folding portion 304 of the cover plate 400 are connected or cover each other to achieve the closure of the modular light-emitting module. At this time, multiple light-guiding structures are arranged between the bracket 300 and the cover plate 400, and only the open end of the cover plate 400 can emit light, thereby improving the light-emitting effect of the modular light-emitting module and solving the problem that the optical teeth of the traditional single light-guiding solution are visible after passing through the transparent mask, affecting the delicate perception, and being unsightly when the lamp is not lit.

[0048] In order to optimize the above technical solution, the modular light-emitting module also includes a fixing portion 402 and an abutting portion 403 fixed to the cover plate 400. The fixing portion 402 includes two relatively arranged bending parts. A receiving cavity for receiving the light mixing portion 100 and the diffusion portion 101 of the light guide structure is formed between the two bending parts. The abutting portion 403 is arranged inside the receiving cavity. When the light mixing portion 100 and the diffusion portion 101 are arranged inside the receiving cavity, the abutting portion 403 abuts against the light mixing portion 100 and / or the diffusion portion 101. Specifically, the abutting portion 403 and the pillar 302 abut against the upper and lower sides of the light guide, respectively. The two bending parts abut against the left and right sides of the light guide, respectively. The light mixing portion 100 of the light guide is connected to the LED light board 200. Such an arrangement realizes the stability of the light guide, so that the operator can place the light guide vertically or horizontally between the cover plate 400 and the bracket 300 according to the lighting effect requirements. Specifically, the two relatively arranged bending parts are in a "Y" shape, so as to be close to the cylindrical light mixing part 100 and the fan-shaped diffusion part 101 to form a stable support for them. Furthermore, the LED light board 200 is placed perpendicular to the plane of the bracket 300, and the cover plate 400 is arranged with a clamping part 404 for clamping the LED light board 200. The clamping part 404, the bending part and the abutting part 403 are all arranged perpendicular to the plane of the cover plate 400, and the bracket 300 is also arranged with a pad 305, and the bottom of the LED light board 200 is arranged on the pad 305 to avoid slipping. Such an arrangement can further ensure the stability of the overall structure of the modular light-emitting module and expand the scope of application of the modular light-emitting module.

[0049] In order to optimize the above technical solution, the number of light guide structures is two or more, and the light guide structures are arranged side by side on the bracket 300. Specifically, by changing the number of light guide structures, the arrangement form of the light guide structures (vertical or horizontal), the number of modular light emitting modules, and the arrangement form of modular light emitting modules, a variety of lighting forms can be formed, including but not limited to: U-shaped arrangement form, three or more modular light emitting modules form a U shape; multi-layer superimposed arrangement form, two or more modular light emitting modules are superimposed, or combined with a single-layer modular light emitting module and other forms. The modular light emitting module disclosed in the utility model can meet a variety of lighting needs, and the angle selection is flexible and diverse. It achieves a dynamic lighting effect through a fixed structure and a variety of arrangements, which can highlight the sense of technology, fun, and ritual.

[0050] like Figure 1 and Figure 7As shown, the vehicle lamp disclosed in the utility model includes a decorative frame 500 and the above-mentioned modular light-emitting module. The top of the decorative frame 500 is connected to the top of the cover plate 400 of the modular light-emitting module, and the bottom of the decorative frame 500 is connected to the bottom of the bracket 300 of the modular light-emitting module. A light outlet 501 is arranged on one side of the decorative frame 500, and the position of the light outlet 501 corresponds to the diffusion part 101 of the light-guiding structure of the modular light-emitting module. Specifically, the connection method of the decorative frame 500 with the cover plate 400 and the bracket 300 can also be a bayonet 401 and a fixing buckle 303 connection. The decorative frame 500 is used to further hide the structure of the modular light-emitting module, thereby improving the aesthetic effect of the vehicle lamp.

[0051] In order to optimize the above technical solution, a protrusion 502 is arranged between the two light outlets 501, and the protrusion 502 is used to block light. Specifically, the side of the protrusion 502 forms an inclined surface at the light outlet 501. When the light guide is lit, the light emitted at an angle is blocked by the inclined surface, so that the light output of the light guide is more complete, and the light formed by the two adjacent light guides after lighting is connected end to end, thereby avoiding the superposition of the light emitted by the two adjacent light guides to generate mixed light, and further improving the lighting effect of the headlight.

[0052] The vehicle lamp provided by the utility model covers the internal structure of the modular light-emitting module through the decorative frame 500, and the light-emitting end of the diffusion part 101 is arranged close to the light-emitting port 501, so that only the light-emitting end can be seen when observing the vehicle lamp from the outside, so that the vehicle lamp has a good lighting effect and visual effect in appearance, and the single light guide solution has a simple structure, can realize dynamic lighting, and has a good application prospect.
