Most existing intelligent interactive front position lights on the market are single-color and low-brightness, only capable of basic welcome animations and front position light functions. They also tend to be visually flat and lack a three-dimensional effect. Therefore, how to innovatively design an RGB ambient light with rich and adjustable colors, combining the functions of daytime running lights and position lights, and achieving dynamic breathing and flowing effects has become a pressing issue. Summary of the Invention

[0003] The purpose of the present invention is to solve the defects and shortcomings in the prior art and provide a fiber optic RGB ambient light for daytime running lights or position lights.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a fiber optic RGB atmosphere light for daytime running lights or position lights, comprising a two-color lampshade and a shell connected to the two-color lampshade. After the two-color lampshade is connected to the shell, an accommodating space is formed inside. An optical thick-walled part and an LED module are arranged in the accommodating space. A plurality of light-guiding optical fibers are injection-molded in the optical thick-walled part. Each of the light-guiding optical fibers has a light mixing area, and a plurality of light source input ends and a plurality of light source output ends respectively connected to the two ends of the light mixing area. The LED module has a plurality of LED groups arranged corresponding to the plurality of light-guiding optical fibers, and the number of LEDs in the LED group is consistent with the number of light source input ends.

[0005] Preferably, the two-color lampshade is composed of colorless and transparent and black, and is made of PC or PMMA. The two-color lampshade is connected to the housing by gluing, hot plate welding or vibration friction welding.

[0006] Preferably, the optical thick-walled component is a colored non-transparent component, and the light transmittance of the optical thick-walled component is 10%-90%.

[0029] like Figure 1-3As shown, the present invention provides a fiber optic RGB atmosphere lamp for daytime running lights or position lights, including a two-color lampshade 1 and a shell 7 connected to the two-color lampshade 1. After the two-color lampshade 1 is connected to the shell 7, an accommodating space is formed inside. An optical thick-walled part 2 and an LED module 5 are arranged in the accommodating space. Specifically, the two-color lampshade 1 is composed of colorless, transparent and black, and the material is PC or PMMA. The two-color lampshade 1 and the shell 7 are connected by gluing, hot plate welding, vibration friction welding and other process forms. The optical thick-walled part 2 is a colored (red, yellow, green, blue, gray, etc.) non-transparent part, and the optical thick-walled part 2 is a colored (red, yellow, green, blue, gray, etc.) non-transparent part. The transmittance is 10%-90%. A number of light-guiding optical fibers 4 are injection-molded in the optical thick-walled part 2. The light-guiding optical fibers 4 adopt a split-combination-split multi-section design, including a light-mixing area 9, and a plurality of light source input ends 8 and a plurality of light source output ends 10 respectively connected to the two ends of the light-mixing area 9, that is, the plurality of light source input ends 8, the light-mixing area 9 and the plurality of light source output ends 10 are connected in sequence according to the direction of the light path. The side of the optical thick-walled part 2 away from the LED module 5 is the light-emitting surface, and the light-emitting surface has an optical pattern 3 arranged corresponding to the light source output end 10. This design is used to optimize the lighting uniformity and weaken the influence of direct bright spots.

[0030] The LED module 5 has several LED groups corresponding to the several light-guiding optical fibers 4. The number of LEDs 6 in the LED groups is consistent with the number of light-entry ends 8 of the light source. At the same time, the several light-guiding optical fibers 4 in the optical thick-walled part 2 can be distributed in an array or specially arranged according to the shape input to achieve a unique optical effect. Specifically, the number of light-guiding optical fibers 4 in the optical thick-walled part 2 ranges from 10 to 600, and the light-guiding optical fibers 4 are colorless and transparent parts made of PC or PMMA.

[0031] In this embodiment, a light-guiding optical fiber 4 is configured with five light source input ends 8 and light source output ends 10. The LED group has five light sources of red, white, yellow, green and blue, which correspond one to one with the five light source input ends 8 respectively, and the five-color light sources can be lit individually or in combination under the action of the driver, and the lighting timing and each brightness can be adjusted. When lit individually, if white light is selected for lighting, the light source branches out through the corresponding light source input end 8 of the light-guiding optical fiber 4, and after being partitioned by the mixing area 9, the white light is diverged and conducted through the divergent light source output end 10 branch. The brightness of the white light is adjusted by controlling the light source parameters, so as to realize the switching of the daytime running light and position light functions. When the light sources on the LED module 5 are combined and lit and their respective brightness ratios are adjusted, multiple beams of light pass through the mixing area 9 to mix various required light colors. By controlling the lighting timing or the lighting color combination, a colorful dynamic atmosphere light effect can be achieved.

[0032] Furthermore, the optical thick-walled member 2 is fastened to the housing 7 by snapping or screwing, and the LED module 5 is assembled to the housing 7 by snapping or riveting.

[0033] The present invention provides a fiber optic RGB atmosphere lamp for daytime running lights or position lights. Through the design of the structure (split-combine-split) of the light-guiding optical fiber 4, the light is first combined and then diverged in the optical thick-walled part 2, and the light is further diffused through the optical pattern 3 on the light-emitting surface of the optical thick-walled part 2 to achieve a uniform lighting effect; through the setting of the driver, the multi-color light source can be lit in a certain order or gradually turned on and off; at the same time, through the opening and closing of the multi-color light source and the combination of different brightness, while realizing the multi-color atmosphere lamp function, it can also be used as a daytime running light and a position light.

[0034] Therefore, the present invention uses an innovative design and combination of optical thick-walled parts that are injection-molded with light-guiding optical fibers. By utilizing simple optical components and cooperating with LED modules with multi-color light sources, a gorgeous multi-color dynamic atmosphere lighting effect can be achieved. At the same time, it can be switched to components with daytime running and position light functions. The effect is novel and gorgeous, which enhances consumers' sense of freshness and experience.

[0035] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
