In this embodiment, the width L is MS cm, and the depth is M U cm. The reflecting surface 23 has a first curved surface portion 231 extending from the outer peripheral edge of the base surface 21 toward the light emitting surface 22, and a peripheral edge extending from the front surface of the first curved surface portion 231 to the periphery of the light emitting surface 22. The second curved surface portion 232. The curvature of the first curved surface portion 231 is greater than the curvature of the second curved surface portion 232. In the present embodiment, the first and second curved surface portions 23i and Μ are the parabolic objects having different curvatures. The refracting concave surface 29 defines a light source space 291 for the light source to be placed, and has a M310992 curved surface portion 292 protruding toward the base surface 21 and having a parabolic shape, and an inner diameter gradually expanding from the The circumference of the arcuate portion 292 extends to the cylindrical portion 293 of the inner periphery of the base surface 21. Therefore, when the light of the light source 1 passes through the refracting concave surface 29 from the air layer and enters the reflective layer 26, a deflection occurs. Then, part of the light is incident on the reflecting surface 23, and after being reflected, it is emitted from the light emitting surface 22, and is 'parallel light that is nearly parallel to the optical axis A; the large four-knife light that is not incident on the reflecting surface 23' The parabolic light-transmissive layer 27 is penetrated, and when it passes through the light surface 25 and enters the air layer, it deflects and converges to become parallel rays that are nearly parallel to the optical axis A. Therefore, the light-transmitting lens holder 2 enables the light of the light source 1 to be emitted by a parallel beam after being refracted and reflected, and is calculated by projecting a predetermined range of light onto a screen of a predetermined area. According to the analysis, the overall light loss rate is only about 15% to 35%, so as to exhibit excellent illuminance and brightness. - In summary, in the light-transmitting lens holder 2 of the present invention, the width L of the light-emitting surface 22 is bounded by 2 to 4 cm, and the artistic ice between the light-emitting surface 22 and the base surface 21 is bounded by ~3 cm, so that the overall light source can be turned into a parallel beam, and the light loss rate is quite low (about Μ%~Μ%), so it can achieve the purpose of this new type of effect. However, the above is only a preferred embodiment of the present invention, and does not limit the scope of the present invention, that is, the simple equivalent change of the patent application and the new description of the present invention. And modifications are still within the scope of this new patent. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 3 is a perspective view showing a preferred embodiment of the light-transmitting lens holder of the present invention, and can be mounted for a light source; and FIG. 2 is a cross-sectional view showing that the preferred embodiment can The incident light of the light source becomes a parallel beam of light.
