[0045] The specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation methods described here are only used to illustrate and explain the present application, and the protection scope of the present application is not limited to the specific implementation methods described below.
[0046] In the description of this application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0047] like Figures 1 to 5 As shown, the first aspect of the present application provides a light-guiding element, comprising a light-focusing portion 1, a light-transmitting portion 2, a reflecting portion 3 and a light-emitting portion 5, the light-focusing portion 1 comprises an upper light-focusing portion 101 and a lower light-focusing portion 102, a first part of the light emitted by the light source is collimated by the upper light-focusing portion 101 and then sequentially emitted through the light-transmitting portion 2 and the light-emitting portion 5, a second part of the light emitted by the light source is collimated by the lower light-focusing portion 102 and then sequentially emitted through the reflecting portion 3, the light-transmitting portion 2 and the light-emitting portion 5.
[0048] In the light-guiding element of the present application, illustratively, the light-focusing portion 1 can be divided into an upper light-focusing portion 101 and a lower light-focusing portion 102 along the central axis in the front-to-back direction thereof. The present application is not limited thereto, and the division of the upper light-focusing portion 101 and the lower light-focusing portion 102 can be set as required, and may not be bounded by the central axis. Exemplarily, the upper light-focusing portion 101, the light-through portion 2, and the light-emitting portion 5 are integrally formed as the upper half of the light-guiding element, and the lower light-focusing portion 102 and a portion of the reflecting portion 3 are integrally formed as the lower half of the light-guiding element. The present application is not limited thereto, and the upper light-focusing portion 101, the lower light-focusing portion 102, the light-through portion 2, and the light-emitting portion 5 can all be integrally formed as a light-guiding element.
[0049] Therefore, different partition structures enable the light introduced into them to form completely different conduction paths:
[0050] like Figure 6 and Figure 7 As shown, the first part of the light enters from the upper light-collecting portion 101, directly passes through the light-transmitting portion 2, and is emitted from the light-emitting portion 5; Fig.10 and Fig.11 As shown, the second part of the light enters from the lower light focusing portion 102 , is reflected multiple times by the reflecting portion 3 , passes through the light passing portion 2 , and is emitted from the light emitting portion 5 .
[0051] It can be seen that since the incident light is divided into multiple different parts for transmission, it is completely different from the traditional light-guiding element that generally reflects or refracts the light incident from the focusing part 1. Part of the light is incident through different positions and then fully reflected by the reflecting part 3 for multiple times to form the illumination light. Since the left and right directions of the light path are wider, the left and right directions of the light-guiding element of the present application are significantly widened, which is 5-6 times that of the existing similar light-guiding elements.
