[0045] The specific embodiments of this application are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this application, and the scope of protection of this application is not limited to the specific embodiments described below.
[0046] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0047] like Figures 1 to 5 As shown, the first aspect of this application provides a light guide element, including a light-concentrating part 1, a light-transmitting part 2, a reflective part 3, and a light-emitting part 5. The light-concentrating part 1 includes an upper light-concentrating part 101 and a lower light-concentrating part 102. A first part of the light emitted from the light source is collimated by the upper light-concentrating part 101 and then passes through the light-transmitting part 2 and the light-emitting part 5 in sequence before being emitted. A second part of the light emitted from the light source is collimated by the lower light-concentrating part 102 and then passes through the reflective part 3, the light-transmitting part 2, and the light-emitting part 5 in sequence before being emitted.
[0048] In the light guide element of this application, exemplarily, the light-concentrating part 1 can be divided into an upper light-concentrating part 101 and a lower light-concentrating part 102 along its central axis in the front-back direction. This application is not limited to this division; the division of the upper light-concentrating part 101 and the lower light-concentrating part 102 can be set as needed and does not necessarily have to be based on the central axis. Exemplarily, the upper light-concentrating part 101, the light-transmitting part 2, and the light-emitting part 5 are integrally formed as the upper half of the light guide element, and a portion of the lower light-concentrating part 102 and the reflective part 3 are integrally formed as the lower half of the light guide element. This application is not limited to this division; the upper light-concentrating part 101, the lower light-concentrating part 102, the light-transmitting part 2, and the light-emitting part 5 can all be integrally formed as a light guide element.
[0049] Therefore, different partition structures allow light rays to form completely different conduction paths:
[0050] like Figure 6 and Figure 7 As shown, the first portion of the light enters from the upper focusing part 101, passes directly through the light-transmitting part 2, and exits from the light-emitting part 5; as Figure 10 and Figure 11 As shown, the second part of the light enters from the lower focusing part 102, is reflected multiple times by the reflecting part 3, and then exits from the light-emitting part 5 via the light-transmitting part 2.
[0051] As can be seen, because the incident light is transmitted in multiple parts, it is completely different from the traditional light guide element which transmits light by reflecting or refracting the light entering from the focusing part 1 in a general way. Some light rays enter from different positions and then undergo multiple total internal reflections by the reflecting part 3 to form illumination light. Because the light path is wider in the left and right direction, the light guide element of this application is significantly wider in the left and right direction, which is 5-6 times wider than existing similar light guide elements. At the same time, both the upper and lower focusing parts emit light from the light emitting part, which increases the light output brightness and further optimizes the light output effect. The structure is simple and the performance is good.
[0052] In a preferred embodiment of this application, the light-transmitting part 2 is provided with:
[0053] The hollow section 4 has alternating sixth reflective surfaces 401 and light-transmitting surfaces 402 on its surface near the light-concentrating section 1.
[0054] The fifth reflective surface 305 is disposed on the side of the light-transmitting part 2 relative to the sixth reflective surface 401.
[0055] like Figure 6 and Figure 7 As shown, the first portion of the light emitted from the light source is collimated by the upper focusing part 101 and then sequentially passes through the light-transmitting surface 402 of the light-transmitting part 2 and the light-emitting part 5 before exiting; as Figure 8 and Figure 9 As shown, the second part of the first part of the light emitted by the light source is collimated by the upper focusing part 101 and then emitted from the light emitting part 5 through the sixth reflecting surface 401 and the fifth reflecting surface 305 of the light transmitting part 2.
[0056] Furthermore, the light-transmitting part 2 is provided with a hollowed-out part 4, which not only effectively reduces the weight of the light guide element, but also, by setting a longitudinal sixth reflective surface 401 and a light-transmitting surface 402 on the hollowed-out part 4, creates a better lighting effect. At the same time, the reflection of the hollowed-out part 4 increases the lateral length of the light-transmitting part, thereby extending the lateral length of the light-emitting part. Preferably, the light-emitting surface of the light-emitting part 5 of a single light guide element in this application is 5-6 times wider than the light-emitting surface of a conventional single light guide element, effectively improving the light emission effect and light emission efficiency.
[0057] As a preferred embodiment of this application, the hollowed-out portion 4 near the light-concentrating portion 1 includes a first reflective surface and a second reflective surface, which form an angle. The first reflective surface and the second reflective surface are respectively provided with an alternately arranged sixth reflective surface 401 and a light-transmitting surface 402. The fifth reflective surface 305 is symmetrically arranged on both sides of the light-transmitting portion 2, and the distance between the two fifth reflective surfaces 305 gradually increases from the light-concentrating portion 1 to the light-emitting portion 5.
[0058] As another specific embodiment of this application, the side of the hollowed-out portion 4 near the light-emitting portion 5 is formed as a hollowed-out portion light-emitting surface 403, and the hollowed-out portion light-emitting surface 403 is arranged parallel to the light-emitting surface of the light-emitting portion 5.
[0059] In a preferred embodiment of this application, the side of the hollowed-out portion 4 near the light-emitting portion 5 is formed as a hollowed-out portion light-emitting surface 403. Each sixth reflective surface 401 is parallel to the fifth reflective surface 305, and the angle between them and the hollowed-out portion light-emitting surface 403 is 45°. Each light-transmitting surface 402 is at an angle of 45° to the fifth reflective surface 305, and is arranged parallel to the hollowed-out portion light-emitting surface 403. The hollowed-out portion light-emitting surface 403 is arranged parallel to the light-emitting surface of the light-emitting portion 5.
[0060] In one specific embodiment of this application, the fifth reflective surface 305 is symmetrically arranged on both sides of the light-transmitting part 2, and the fifth reflective surface 305 gradually extends outward from back to front, thereby increasing the length of the front half of the light-transmitting part 2 in the left and right direction, thereby effectively widening the length of the light-emitting surface of the light-emitting part 5 in the left and right direction.
[0061] In a preferred embodiment of this application, the hollowed-out part 4 is a triangular hollowed-out structure or a pentagonal hollowed-out structure, and the light-transmitting part 2 runs through it from top to bottom.
[0062] In one specific embodiment of this application, the area of the triangular hollow structure is increased according to actual usage requirements, thereby effectively meeting the light emission requirements while minimizing the weight of the light guide element and reducing production costs.
[0063] In a preferred embodiment of this application, the reflective part 3 includes a first reflective part and a third reflective surface 303. The first reflective part is disposed corresponding to the lower focusing part 102, and the third reflective surface 303 is disposed corresponding to the upper focusing part 101. The second part of the light emitted from the light source is collimated by the lower focusing part 102 and then passes through the first reflective part, the third reflective surface 303, the light-transmitting part 2, and the light-emitting part 5 in sequence before being emitted.
[0064] More preferably, the first reflective part includes a first reflective surface 301, a second reflective surface 302 and a fourth reflective surface 304. The first reflective surface 301 and the second reflective surface 302 are connected and located in the light-emitting direction of the lower light-concentrating part 102. The third reflective surface 303 and the fourth reflective surface 304 are connected and disposed on the side of the light-concentrating part 1.
[0065] More preferably, the first reflecting surface 301 and the second reflecting surface 302, which are used to reflect light to the same fourth reflecting surface 304, are connected to form a V-shape, with the tip of the V-shape facing the light emission direction. The third reflecting surface 303 and the fourth reflecting surface 304 are connected to form a V-shape, with the tip of the V-shape facing away from the light emission direction. Thus, the light from the lower focusing part 102 is broadened in the left / right direction by the first reflecting surface 301 and the second reflecting surface 302 to be reflected to the fourth reflecting surface 304. The light from the fourth reflecting surface 304 can also be further broadened by the hollowed-out part 4 provided on the light transmission part 2.
[0066] In a preferred embodiment of this application, the third reflective surface 303 and the fourth reflective surface 304 are connected and respectively disposed on both sides of the light-concentrating part 1, and the first reflective surface 301 and the second reflective surface 302 are arranged alternately to form a W shape.
[0067] As a specific embodiment of this application, the application has two first reflective surfaces 301 and two second reflective surfaces 302, which are arranged alternately to form a W shape. The intersection angle of adjacent first reflective surfaces 301 and second reflective surfaces 302 is preferably 90 degrees. A third reflective surface 303 and a fourth reflective surface 304 are provided on both sides of the light-concentrating part 1, and the included angle between the third reflective surface 303 and the fourth reflective surface 304 on one side is preferably 90 degrees. Thus, it can be seen that the first reflective surface 301, the second reflective surface 302, the third reflective surface 303, and the fourth reflective surface 304 are all formed as 45° reflective surfaces.
[0068] In a preferred embodiment of this application, the included angle between the first reflective surface 301 and the second reflective surface 302 is 85-95 degrees, and the included angle between the third reflective surface 303 and the fourth reflective surface 304 is 85-95 degrees. Preferably, the included angle between the first reflective surface 301 and the second reflective surface 302 is 90 degrees, and the included angle between the third reflective surface 303 and the fourth reflective surface 304 is 90 degrees.
[0069] As a preferred embodiment of this application, patterns such as columnar stripes or corn kernel patterns are provided on the surfaces of the upper focusing part 101 and / or the lower focusing part 102, the light-emitting surface of the light-emitting part 5, one or more of the reflective surfaces of the first reflective surface 301, the second reflective surface 302, the third reflective surface 303, the fourth reflective surface 304 and the fifth reflective surface 305, and the light-emitting surface 403 of the hollow part, thereby effectively improving the uniformity of lighting.

On the surface of the hollow part 4 near the light-concentrating part 1, there are alternately arranged sixth reflective surfaces 401 and light-transmitting surfaces 402. The fifth reflective surface 305 is disposed on the side of the light-transmitting part 2 relative to the sixth reflective surface 401. The reflecting part 3 includes a first reflecting part and a third reflecting surface 303. The first reflecting part includes a first reflecting surface 301, a second reflecting surface 302, and a fourth reflecting surface 304. The first reflecting surface 301 and the second reflecting surface 302 are connected and located in the light-emitting direction of the lower focusing part 102.

The first reflective surface 301 and the second reflective surface 302 are alternately arranged to form a W shape. The first reflective surface 301 and the second reflective surface 302 used to reflect to the same fourth reflective surface 304 are connected to form a V shape, and the tip of the V shape is set facing the light-emitting direction. The third reflective surface 303 and the fourth reflective surface 304 are connected to form a V shape, and the tip of the V shape is set away from the light-emitting direction. The first reflective part is disposed corresponding to the lower light-concentrating part 102. The hollow part 4 near the light-concentrating part 1 includes a first transparent reflective surface.
