In the prior art, a multi-color LED light source is generally used to mix the required light color by adjusting the electronic signal, but this implementation method needs to be used with corresponding electronic control elements, and the cost of the multi-color LED light source is much higher than that of the commonly used monochromatic LED light source, thereby increasing the cost of the product. SUMMARY

[0003] In view of the above problems, the utility model aims to design a multi-color light guide and a light emitting assembly, which can emit multi-color light by combining a plurality of monochromatic light sources, thereby achieving the purpose of reducing cost.

[0004] The utility model aims to achieve the following technical scheme:

[0005] The utility model discloses a multi-color light guide, which comprises a light guide main body and a plurality of light source receiving parts connected with the light guide main body, the light guide main body comprises an outlight surface for emitting light, each light source receiving part comprises an inlight surface and a plurality of reflection light guide surfaces, and the plurality of reflection light guide surfaces are used for reflecting the incident light from the inlight surface into the light guide main body.

[0006] The multi-color light guide designed in the utility model can be integrally formed by PC transparent material or optical glass, a plurality of light source receiving parts can receive monochromatic light of different colors, the light rays change the angle of propagation after passing through the plurality of reflection light guide surfaces after being emitted from the light source receiving part through the inlight surface, finally enter the light guide main body and propagate in the light guide main body, the shape of the light guide main body is designed according to actual use requirements, meanwhile, the outlight surfaces at different positions can be designed to realize the emission of light rays from different positions, therefore, by using the multi-color light guide and cooperating with monochromatic LED light sources of different colors, the outlight surfaces of the multi-color light guide can emit light rays of different colors in turn and uniformly by controlling the on-off of the LED light sources of different colors, and the cost is greatly reduced compared with the use of multi-color LED light sources.

[0007] Further, the light guide main body comprises a light guide column, one end of the light guide column is connected with the plurality of light source receiving parts, and the other end extends to both sides to form a light guide ring.

[0008] In the scheme, the light guide column extends to both sides to form two parallel and connected light guide rings. The light guide rings can be circular, elliptical, or long circular in shape. The light guide column is connected to the light source receiving part. The light source receiving part conducts light according to the predetermined light path, so that the light can be uniformly guided to the light guide column, and then the light propagates to the entire light guide.

[0009] Further, the plurality of reflective light guide surfaces include a first reflective light guide surface adjacent to the light guide column. The first reflective light guide surface uniformly reflects light into the light guide column.

[0010] The first reflective light guide surface is directly connected to the light guide column. The angle between the first reflective light guide surface and the light guide column is designed according to actual needs to ensure that the light can be uniformly incident into the light guide column.

[0011] Further, the light guide column near one end of the light guide ring is provided with a light splitting structure. The light splitting structure is used to disperse the light conducted in the light guide column to two light guide rings.

[0012] After the light propagates through the light guide column, it needs to be evenly divided into two light guide rings. Therefore, a light splitting structure is designed at the end of the light guide column to separate the light.

[0018] The scheme sets different color single-color LED light sources on the light entering surface. The LED light sources are controlled to turn on and off in turn, so that the light emitting surface of the multi-color light guide piece uniformly emits different color light in turn. The light disperses after entering the light dispersing piece, forming a multi-color light structure.

[0019] Further, the light dispersing member comprises a shielding part and a light emitting ring arranged on the shielding part, and the light emitting surface is attached to the light emitting ring.

[0021] Further, the LED light source is arranged on the side of the shielding part away from the light emitting ring.

[0022] The shielding part blocks the light emitted by the LED light source, so that the light rays emitted by the LED light source do not directly irradiate on the light emitting ring, and the light emitting ring is not unevenly bright and dark, and the visual effect is affected.

[0023] Further, the shielding part is provided with a notch corresponding to the light source receiving part, and the light source receiving part is arranged opposite to the LED light source through the notch.

[0024] The LED light source is arranged on the side of the shielding part away from the light emitting ring, and after the multi-color light guide member is sleeved on the light emitting ring, the light source receiving part passes through the corresponding notch, so that the light emitting surface can face the LED light source and receive as many light rays as possible emitted by the LED light source.

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] The multi-color light guide member designed in the scheme can be integrally formed by PC transparent material or optical glass, and through the design of the plurality of light source receiving parts, different colors of monochromatic light can be received, the light rays are emitted from the light emitting surface to the light source receiving part, the angle of the light rays is changed through the plurality of reflection light guide surfaces, and finally the light rays enter the light guide main body and propagate in the light guide main body. The shape of the light guide main body is designed according to actual use requirements, and meanwhile, the light emitting surfaces at different positions can be designed to realize the emission of light rays from different positions. Therefore, by using the multi-color light guide member and different colors of monochromatic LED light sources, the light emitting surface of the multi-color light guide member can emit different color light rays uniformly in sequence by controlling the on-off of different colors of LED light sources, and the cost is greatly reduced compared with the use of multi-color LED light sources.

[0034] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Example 1:

[0035] like Figures 1 to 4 As shown, this embodiment provides a multi-color light guide 1, including a light guide body 11 and a plurality of light source receiving parts 12 connected to the light guide body 11. In this embodiment, two light source receiving parts 12 are provided. In other possible embodiments, the number of light source receiving parts 12 may be different, and no specific limitation is made here. The light guide body 11 includes a light emitting surface 111 for emitting light. Each light source receiving part 12 includes an incident surface 121 and a plurality of reflective light guiding surfaces. The plurality of reflective light guiding surfaces are used to reflect the incident light rays emitted from the incident surface 121 and guide them into the light guide body 11.

[0036] The multicolor light guide 1 designed in the scheme can be designed in one piece by PC transparent material or optical glass. Two light source receiving parts 12 are designed to receive two colors of monochromatic light. After the light is emitted from the light receiving part 12 through the light receiving surface 121, the angle of the light propagation is changed through several reflection light guide surfaces, and finally enters the light guide main body 11 and propagates in the light guide main body 11. The shape of the light guide main body 11 is designed according to the actual use requirement, and the light emitting surface 111 at different positions can be designed to realize the emission of light from different positions. Therefore, by using the multicolor light guide 1 and different color monochromatic LED light sources, and by controlling the on-off of different color LED light sources, the light emitting surface 111 of the multicolor light guide 1 can emit different color light in turn. Compared with the use of multicolor LED light source, the cost is greatly reduced.

[0037] As shown in Figures 1 to 4 The light guide main body 11 includes a light guide column 113, one end of which is connected with the light source receiving part 12, and the other end extends to both sides to form a light guide ring 112. In this embodiment, the light guide column 113 extends to both sides to form two parallel and connected light guide rings 112. The light guide ring 112 can be a circular ring, an elliptical ring, a long circular ring, etc. The light guide column 113 is connected with the light source receiving part 12 at the place where the two light guide rings 112 are parallel and connected. The light source receiving part 12 conducts light according to the predetermined light path, so that the light can be uniformly guided to the light guide column 113, and then the light propagates to the entire light guide ring 112. The inner surface of the light guide ring 112 is the light emitting surface 111, and the light is emitted from the inner surface of the light guide ring 112 to form a bright surface light ring.

[0038] As shown in Figures 1 to 4 In this embodiment, the light source receiving part 12 includes a first reflection light guide surface 122, a second reflection light guide surface 123 and a third reflection light guide surface 124. The first reflection light guide surface 122 is directly connected with the light guide column 113. The second reflection light guide surface 123 is opposite to the light receiving surface 121. The third reflection light guide surface 124 is located between the first reflection light guide surface 122 and the second reflection light guide surface 123. The second reflection light guide surface 123 can be a reflection plane or a reflection curved surface, which changes the light path of the incident light to 90 degrees to shoot to the third reflection light guide surface 124. The third reflection light guide surface 124 changes the angle of the light again to shoot to the first reflection light guide surface 122. The first reflection light guide surface 122 uniformly reflects the light into the light guide column 113. The angle between the first reflection light guide surface 122 and the light guide column 113 is designed according to the actual requirement to ensure that the light can be uniformly emitted into the light guide column 113. In addition, the angle and number of reflection light guide surfaces are designed according to the position of the light source and the structure of the product to be used. Different structures will have certain differences, but the design principle is the same. Therefore, in other possible embodiments, there can be different numbers of reflection light guide surfaces.

[0039] As shown in Figures 1 to 4 the light guide column 113 is provided with a light splitting structure 114 near one end of the light guide ring 112, and the light splitting structure 114 is used to disperse the light conducted in the light guide column 113 to the two light guide rings 112. After the propagation of the light in the light guide column 113, the light needs to be evenly divided into the two light guide rings 112, so the light splitting structure 114 is designed at the intersection of the two light guide rings 112 to separate the light, part of the light enters one light guide ring 112, and part of the light enters the other light guide ring 112. The light propagates in the light guide ring 112 and is emitted from the light emitting surface 111. In this embodiment, the light splitting structure 114 is a V-shaped light splitting groove, and the light splitting groove is opposite to the middle position of the light guide column 113. The two inclined surfaces of the V-shaped groove reflect the incident light to the two sides respectively, and two light paths entering the two light guide rings 112 are formed respectively. Embodiment two:

[0040] As shown in Figure 5 and Figure 6 this embodiment provides a light emitting assembly, which comprises the above-mentioned multi-color light guide piece 1, two single-color LED light sources 2 of different colors arranged one by one corresponding to the light entering surface 121, and a light dispersing piece 3 attached to the multi-color light guide piece 1. By arranging the single-color LED light sources 2 of different colors on the light entering surface 121, the LED light sources 2 are controlled to turn on and off in turn, and then the light emitting surface 111 of the multi-color light guide piece 1 uniformly emits light of different colors in turn. After the light enters the light dispersing piece 3, it is dispersed, forming a multi-color light bright structure. The light dispersing piece 3 comprises a shielding part 31 and a light emitting ring 32 arranged on the shielding part 31, and the light emitting surface 111 is attached to the light emitting ring 32. The light guide ring 112 of the multi-color light guide piece 1 is sleeved on the light emitting ring 32, and the inner surface of the light guide ring 112 is the light emitting surface 111. The light emitting surface 111 is attached to the light emitting ring 32, and the light emitted from the light emitting surface 111 enters the light emitting ring 32 and scatters in the light emitting ring 32, forming a light ring. The LED light source 2 is located on the side of the shielding part 31 away from the light emitting ring 32, and the shielding part 31 blocks the light emitted by the LED light source 2, avoiding the direct irradiation of the light of the LED light source 2 to the light emitting ring 32, which causes the light emitting ring 32 to be unevenly bright and dark, affecting the visual effect. In addition, the shielding part 31 is provided with a notch 311 corresponding to the light source receiving part 12, and after the multi-color light guide piece 1 is sleeved on the light emitting ring 32, the light source receiving part 12 passes through the corresponding notch 311, so that the light entering surface 121 can face the LED light source 2 and receive as much light as possible emitted by the LED light source 2.
