For example, Taiwan Patent No. 12616 can not be exposed in the uniform light-emitting diode of the mirror. The face is a continuous curved surface of the 200933086 mirror. The working surface of the mirror body defines a - divergent surface, the divergent surface = surface) = central is - concave and the high light intensity distribution light: over::::: pole: near the optical axis 'to make the light dipole The body can emit a lighter than the optical axis, and the conventional structure is true; and the light of the uniform sentence distribution; only:, teeth, use! In the test, it is found that the following problems still exist: 〇1=The continuous curved surface by which the refracted light effect is achieved is provided on the end face), and thus, since the work is uneven, and the action surface of the mirror body is applied It is usually an exposed part when the lamps are used, so it is easy to hide the dirt, ", inconvenient, and it becomes a disease. 2. Since the action surface of the mirror body is a continuous curved surface and unevenness, when the f industry wants to cover a surface of the active surface with a light diffusing film to further enhance the light self-effect, it will be a lack of flat stickers. There are problems and shortcomings that are difficult to implement. Secondly, in view of the problems in the use of the above-mentioned conventional LED light guiding lens structure, how to develop an innovative structure that can be more ideal and practical, and the relevant industry should further consider the goal and direction of breakthrough. In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention. SUMMARY OF THE INVENTION 6 200933086 The main object of the present invention is to provide a LED light guiding lens structure capable of uniformly guiding light, and the problem to be solved is to refract light for a conventional light guiding lens structure design. The curved surface is located on the external working surface of the mirror body, and there is still a problem that the valley is easy to hide dirt, the cleaning is inconvenient, and it is difficult to attach the light diffusion film; the light guiding lens is a three-dimensional sadness The invention is characterized in that the light guiding lens comprises: a light guiding surface, which is disposed on the outer side of the light guiding lens, and the light guiding surface can be a flat surface or a curved surface type; The led projection space is disposed on the inner side of the light guiding lens for aligning the LEDs therein, and the inner end of the LE:D projection space is defined and formed with an inner wall corresponding to the LED spacing; a curved light guiding surface is disposed in the inner casing The curved light guiding surface includes a concave divergent region in the center and a convex concentrating region located at the periphery of the concave divergent region; thereby, the innovative and unique design enables the present invention to be compared with the prior art. The following advantages can be achieved: First, since the curved light guiding surface is disposed inside the inner wall of the LE1D projection space, the outer side of the light guiding lens can be set as a flat surface of the light guiding surface. Therefore, the light guiding lens can extract light of a large area and a uniform sentence distribution, and can achieve practical progress of preventing dirt and dirt from being cleaned and cleaned. The curved light guiding surface is disposed on the inner wall of the LED projection space, and the outer side of the light guiding lens is designed to be a light-conducting surface, so that the light guiding lens can output a large area and a uniform sentence light, and The flat surface pattern of the light-extracting surface is more convenient for the light-diffusing film to be attached to the binder 7 200933086 [Embodiment] μ refers to FIG. 2, which is a preferred embodiment of the light guiding lens structure capable of uniformly guiding the light of the present invention. For example, the embodiments are for illustrative purposes only and are not limited by the structure in the patent; the light guiding lens is a light transmissive body having a three-dimensional shape, which comprises the following components: The light V exiting surface 20 ′ sighs on the outer side portion u of the light guiding lens 10, and the light guiding surface 20 can be set to a flat surface type 'can also be set as a curved surface type; at least one LED projection space 30 is provided The inner side portion 12 of the light guiding lens 1 is disposed therein for 40 pairs of positions, the inner end of the LED projection space 3 is defined and formed with an inner wall 31 corresponding to the LED spacing; and is disposed on the inner wall The curved light guiding surface of the 31 is 5〇, and the curved light guiding surface 5〇 is located a concave divergent region Η in the central portion, and a convex condensing region 52 located at a periphery of the concave divergent region 51, wherein the thickness of the concave divergent region 51 is increased from the inside to the outside, the convex poly The thickness of the light region 52 is reduced from the inside to the outside. By using the above-described structural composition design, the state of use of the present invention will be described as follows: As shown in FIG. 3, the structural design of the curved light guiding surface 50 is provided by the inner wall 31 of the LED projection space 30 so that The light emitted by the LED 40 is close to the optical axis L region thereof. It can be diffused outward by the concave divergent region 51 in the center of the curved light guiding surface 50, and the convex concave portion of the concave concave portion 51 is convex. The light region 52 can agglomerate and strengthen the weaker peripheral light, thereby obtaining an area widening (as indicated by W in the figure) and uniform light guiding effect. In the inner portion 12 of the light guiding lens 10, the LED projection space 30 may be in a single set type (as shown in FIGS. 1 and 2); or the light guiding lens 10B as shown in FIG. 4, the LED thereof The projection space 30 is a pattern of a plurality of spaced-apart distributions; as shown in FIG. 5, the light guiding surface of the light guiding lens 1B can be combined with a light diffusing film 60, thereby achieving a more It is a light guiding effect that spreads evenly. Wherein, when the LED projection space 30 is arranged in a complex array interval arrangement, it may be in a form of mutual alignment (as shown in FIG. 6) or a pattern in which Q is shifted from each other (as shown in FIG. 7). . Wherein the side portion between the inner and outer portions 11, 12 of the light guiding lens 1 〇 (or 1 〇 B) may be provided with a tapered side wall. As shown in FIG. 8 , another embodiment of the structure of the light guiding lens 1 , is different from the previous embodiment, mainly because the curved light guiding surface is The configuration of the inner side portion 12β of the light guiding lens 1β without the LED projection space 30 can also be adopted by the concave divergent region 51 and the convex condensing region in the curved light guiding surface 50. 52, and obtain a wide-area and uniform light guiding effect. Advantages of the invention: 1. The invention mainly adopts the built-in design of the curved light guiding surface disposed in the interior of the LED projection space, so that the outer side of the light guiding lens can be set as the flat state of the light guiding surface.
