In the existing solutions for multiplexing the functions of lamps, when the steering and position functions share a light outlet, a direct or reflective solution is adopted, and the LED light is emitted after passing through a series of structures. However, in this case, regardless of the direct or reflective concentrator solution, since the concentrator has only one focus, at least one of the two light colors will be out of focus, resulting in energy loss, low light efficiency, increased power consumption, and the light patterns of each function will be offset.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example:

[0034] like Figures 1 to 7As shown, a functional multiplexing light-focusing structure comprises: a main body 1, a light-emitting portion 2 is provided on one end surface of the main body 1; a light-entering portion 3, the light-entering portion 3 comprises a total reflection portion 4, a first refraction portion 5 and a second refraction portion 6, the total reflection portion 4 is wrapped around the first refraction portion 5, the second refraction portion 6 is respectively connected to the inner edge of the total reflection portion 4 and the outer edge of the first refraction portion 5, the outer edge of the total reflection portion 4 is connected to the outer edge of the light-emitting portion 2, the distance between the first refraction portion 5 and the light-emitting portion 2 is defined as L1, the distance between the connection between the second refraction portion 6 and the inner edge of the total reflection portion 4 and the light-emitting portion 2 is defined as L2, L2 is greater than L1, the first refraction portion 5 corresponds to at least a portion of the light emitted by the first focus 7 and the second focus 8, and the second refraction portion 6 corresponds to at least a portion of the light emitted by the first focus 7 and the second focus 8.

[0035] The first refractive portion 5 includes a plurality of first refractive surfaces 9 and a plurality of second refractive surfaces 10, with a point defined as a center point O. The first refractive surfaces 9 and the second refractive surfaces 10 form a circular array with the center point O as the center of the circle. The first refractive surfaces 9 and the second refractive surfaces 10 are arranged at intervals, and a step is formed at the connection between the first refractive surfaces 9 and the second refractive surfaces 10. The first refractive surfaces 9 and the second refractive surfaces 10 respectively correspond to at least a part of the light emitted by the first focus 7 and the second focus 8. The first refractive surfaces 9 and the second refractive surfaces 10 include but are not limited to sectors, and may also be other structures capable of refracting light, such as squares, triangles, etc.

[0036] A portion of the incident light emitted from the first focus 7 and the second focus 8 is projected onto the first refractive surface 9 and the second refractive surface 10 respectively to form collimated light, which is then projected onto the light emitting portion 2 to form emitted light.

[0037] That is to say, a portion of the light emitted by the first focus 7 and the second focus 8 only needs to be refracted once by the first refractive surface 9 and the second refractive surface 10 to form a collimated output light. At this time, the output light has a short propagation path in the focusing structure of this embodiment. Therefore, the light type of the output light formed by the light emitted by the first focus 7 and the second focus 8 can be well guaranteed.

[0038] A connecting surface 11 is connected between the first refractive surface 9 and the second refractive surface 10, and the connecting surface 11 forms an angle with the first refractive surface 9 and the second refractive surface 10 respectively, so that the adjacent first refractive surface 9 and the second refractive surface 10 are located in different planes. The setting of the connecting surface 11 here is a step setting, so that the first refractive surface 9 and the second refractive surface 10 are located in different planes, that is, there is an angle between the first refractive surface 9 and the second refractive surface 10. When the other part of the light emitted from the first focus 7 and the second focus 8 passes through the first refractive surface 9 and the second refractive surface 10, it can form a variety of collimated emergent light rays, respectively, forming visually transparent and beautiful emergent light rays.

[0039] The second refractive portion 6 is cylindrical, and the diameter of the junction between the second refractive portion 6 and the total reflection portion 4 is larger than the diameter of the junction between the second refractive portion 6 and the total reflection portion 4 .

[0040] The total reflection portion 4 is cylindrical, and the diameter of the joint between the total reflection portion 4 and the light emitting portion 2 is larger than the diameter of the joint between the total reflection portion 4 and the second refractive portion 6 .

[0041] The total reflection portion 4 has a plurality of first total reflection surfaces 12 and a plurality of second total reflection surfaces 13, which are arranged at intervals on the side of the total reflection portion 4, and a step is formed at the connection between the first total reflection surface 12 and the second total reflection surface 13. The first total reflection surface 12 and the second total reflection surface 13 correspond to at least a portion of the light emitted by the first focus 7 and the second focus 8, respectively. It can also be said that the first total reflection surface 12 and the second total reflection surface 13 correspond to another portion of the light emitted by the first focus 7 and the second focus 8, respectively. The first total reflection surface 12 and the second total reflection surface 13 include but are not limited to fan shapes, and may also be other structures that can perform total reflection of light, such as squares, triangles, etc.

[0042] Another part of the incident light emitted by the first focal point 7 and the second focal point 8 is projected onto the second refractive portion 6 respectively, and the light refracted by the second refractive portion 6 is projected onto the first total reflection surface 12 and the second total reflection surface 13 respectively, and is totally reflected by the first total reflection surface 12 and the second total reflection surface 13 to form collimated light, which is projected onto the light output portion 2 to form output light.

[0043] That is to say, the other part of the incident light emitted by the first focus 7 and the second focus 8 needs to pass through the second refractive portion 6 and any one of the first total reflection surface 12 and the second total reflection surface 13 in succession before it can form a collimated outgoing light. At this time, the outgoing light is refracted and totally reflected in succession in the focusing structure of this embodiment. Therefore, the lighting area of ​​the outgoing light can be increased, which is equivalent to using a limited number of focal points to achieve a larger area lighting effect, greatly improving the utilization rate of light energy. The paths of the two parts of the incident light emitted by the first focus 7 and the second focus 8 are independent, which can well avoid the situation where the light color is out of focus when the focusing structure has two light colors, thereby reducing energy loss.

[0044] The side surface of the total reflection portion 4 is convex in a direction away from the axis of the total reflection portion 4 , and the axis of the total reflection portion 4 is at the center point O.

[0045] A connecting surface 11 is connected between the first total reflection surface 12 and the second total reflection surface 13 , and the connecting surface 11 forms an angle with the first total reflection surface 12 and the second total reflection surface 13 respectively, so that the adjacent first total reflection surface 12 and the second total reflection surface 13 are located in different planes.

[0046] A connecting surface 11 is connected between the first total reflection surface 12 and the second total reflection surface 13, and the connecting surface 11 forms an angle with the first total reflection surface 12 and the second total reflection surface 13 respectively, so that the adjacent first total reflection surface 12 and the second total reflection surface 13 are located in different planes. The setting of the connecting surface 11 here is a step setting, so that the first total reflection surface 12 and the second total reflection surface 13 are located in different planes, that is, there is an angle between the first total reflection surface 12 and the second total reflection surface 13. When another part of the incident light emitted by the first focal point 7 and the second focal point 8 passes through the first total reflection surface 12 and the second total reflection surface 13, it can form a variety of collimated emergent light rays, respectively, to form visually transparent and beautiful emergent light rays.

[0047] In summary, based on the above-mentioned ideal embodiments of the utility model, through the above-mentioned description, relevant personnel can make various changes and modifications without departing from the technical concept of the utility model. The technical scope of the utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
