[Prior Art ★, the existing optical diffusing element, such as China's special 4 4 5 "optical diffusion layer 1 diffusion plate and optical component H case, which is mainly by sand blasting or chemical money engraving, etc." Hey,... know that the October coating is convex, .'. a structure in which the average value of the peak-to-peak distance (Sm) having a fine ridge, the average of the medium (10), the surface roughness and the surface roughness (R) satisfy the following formula: Sm It is called micron, Raq / thousand mean system and its surface is fine (4) and _. ^ The uneven structure is mainly formed of organic particles or the like. Do not smash the optical diffusing element of the structure, ^, mainly use organic particles, etc. = fine phase convex structure, (4) frequency light dispersion: liter optics to U light, the degree of self-degree, the brightness of the fairy is insufficient, etc. The land will also lead to lack of light, so there is a need to improve it. SUMMARY OF THE INVENTION The main object of the present invention is to provide a base (four) structure for solving the above problems. The first four systems are blended with a material of a square light structure which is formed by roll extrusion molding and then cured. Most of the diffusing particles H precede the 弁学云 A by the AM to spread the particles to diffuse the light, and then the light collecting structure concentrates the light output, 1279591 to achieve the effect of increasing the luminance value of the output. The above and other objects and advantages of the present invention will be readily understood from Of course, the invention may be varied on certain components or arrangements of parts, but the selected embodiments are described in detail in the specification and their construction is shown in the drawings. [Embodiment] - Please refer to Fig. 1 and Fig. 2'. The structure shown in the figure is the structure of the embodiment selected for the present invention, which is only for the use of this article, and is not applicable to patent applications. The limitations of the structure. The optical element of this embodiment comprises a substrate 1 and a light collecting structure 1. The substrate 1 is made of a plastic material, and in this embodiment, the substrate 1 is a film made of polyethylene terephthalate (PET). The light collecting structure 2 is formed by rolling and forming a roller, and is formed on the substrate 1h. The surface of the light collecting structure 2 is a smooth surface, and the material of the light collecting structure 2 is blended with a majority diffusion. In the present embodiment, each of the diffusion particles 2 i is a polymethylmethacrylate formazan powder (= PowderMi dream powder (Si〇2 shouting, etc., so that the light is diffused by the diffusion particles 1 1 to the optical element) The middle hook is diffused, and the light collecting structure 2 is used to rotate the light assembly. The light collecting structure 2 is a plurality of juxtaposed strip structures, and the surface thereof is a smooth surface, and each strip structure is broken. The surface is roughly arc-shaped, and its height coordinate width coordinates [the odds constant is c, the aspheric coefficient is wide conic constant k, -I<k<G table ellipse, k__Q table circle, ^ table oblate 1279951 shape' And each section of the strip structure must satisfy the following formula:
Z cY2 + +β3γ3 +β4γΑ+β5γ5+β6γβ ^βηΥι + β^% 而本發明之光學元件其製程，係先將押出機之滾輪以 機械加工方式形成所需之結構形狀，再將紫外線固化性樹 脂或熱固化性樹脂與擴散粒子2 μ句混合成為成形膠， 而後將成形膠塗佈於滾輪上，再將基材[贴附在附著有成 形膠之滾輪上，並以滾輪將基材i壓平貼附，且以UVS 照射25_j/cm2的能量（或於高溫爐中加熱）後固化，最 後將基材1自滾輪上剝下，即可於基材1Jl形成所需特定 結構形狀之集光結構2。 據此，上述特定形&之集光結構2可將光學元件中被 擴散粒子2 1散射而均句分佈之光線集中輪出，而可增進 其輸出之輝度值。 θ 當然，亦可將本發明條狀之集光結構的表面設計成霧 面如第3圖所不，使其表面粗才造度Ra=〇.卜25〇咖，如此 可更進-步使光學元件輸出之集中光線擴散而更為均句， 而該基材1遠離該集光結構2之—面，以及該集光結構2 與絲材i結合之—面均可設計為霧面形態，而其表面粗 糖度 Ra=0· 1 〜250um。Z cY2 + +β3γ3 +β4γΑ+β5γ5+β6γβ ^βηΥι + β^% The optical component of the present invention is processed by first forming the desired shape of the roller of the extruder by mechanical processing, and then curing the ultraviolet curable resin. Or the thermosetting resin is mixed with the diffusion particles in 2 μs to form a molding gel, and then the molding gel is coated on the roller, and then the substrate is attached to the roller to which the molding gel is attached, and the substrate i is pressed by the roller. It is attached flat and cured by UVS irradiation of 25_j/cm2 (or heating in a high-temperature furnace), and finally the substrate 1 is peeled off from the roller to form a desired specific structure shape on the substrate 1J1. Structure 2. Accordingly, the light collecting structure 2 of the above-described specific shape & can scatter the light particles scattered by the diffusing particles 21 in the optical element and uniformly distribute the light, thereby increasing the luminance value of the output. θ Of course, the surface of the strip-shaped light collecting structure of the present invention can also be designed as a matte surface as shown in FIG. 3, so that the surface roughness is Ra=〇. 〇25〇, so that it can be further improved. The concentrated light output from the optical component is diffused and more uniform, and the substrate 1 is away from the surface of the light collecting structure 2, and the surface of the light collecting structure 2 combined with the wire i can be designed as a matte surface. The surface roughness is Ra=0·1 to 250um.
