Embodiment
For the purpose of this utility model, feature and advantage can be understood by clearer and more definite quilt, the utility model preferred embodiment cited below particularly and conjunction with figs. elaborate.
Please refer to shown in Figure 4ly, the bending prism concentration piece of the utility model first embodiment comprises a substrate 3 and several bending prism unit 4, and it can utilize integrally formed mode to make by identical light-transmitting materials.Substrate 3 has a first surface 31 and a second surface 32, and can wear for light and penetrate process.Bending prism unit 4 belongs to the microstructure layer, and it adjoins each other on the first surface 31 (or second surface 32) that is arranged in substrate 3.Each bending prism unit 4 is provided with one first crooked curved surface 41a of extension and the one second crooked curved surface 41b that extends.Textural, the crooked extension between the first and first crooked extension curved surface 41a, the 41b that defines a crest line 42, two adjacent bending prism unit 4 between curved surface 41a, the 41b jointly of first and second of each bending prism unit 4 then defined a trough conllinear 43 (end periphery boundary) jointly.
Please refer to shown in Figure 4ly, in the utility model first embodiment, list on the first surface 31 of substrate 3 according to identical irregular curved path change mode adjacent rows each two adjacent bending prism unit 4.Simultaneously, with respect to substrate 3, each bending prism unit 4 is preferable keeps vertical height H that roughly essence is identical and horizontal width w (width that two adjacent ribs lines 42 are folded).In other words, be arranged parallel to each other though two adjacent bending prism unit 4 roughly are, each bending prism unit 4 still has the first irregular curved crooked curved surface 41a of extension and the second crooked curved surface 41b that extends, so suitable surface curvature can be provided.By this, when light is incident to bending prism unit 4 by the appropriate location of substrate 3, the first crooked curved surface 41a of extension and the second crooked bootable light tendency of surface curvature of extending curved surface 41b produce the two dimension refraction, thereby promote the spotlight effect of bending prism unit 4 and whole concentration piece effectively relatively.
Moreover bending prism of the present utility model unit 4 forms the folded line phenomenon of irregular curved path arrangement also can minimizing generation, thereby can promote the optics demonstration image quality of the utility model concentration piece relatively.In addition, compared to the concentration piece of commonly using of the tool of Fig. 3 two dimension refracting characteristic, bending prism of the present utility model unit 4 also has than simple structure, therefore also helps reducing die sinking cost and production cost.
Please refer to shown in Figure 5ly, disclose the bending prism concentration piece of the utility model second embodiment.Compared to first embodiment, each adjacent flex prism elements 4 of second embodiment has the identical vertical height H of essence, but further form varying level width w, so list on the first surface 31 of substrate 3 according to different irregular curved path change mode adjacent rows each two adjacent bending prism unit 4.In other words, each two adjacent bending prism unit 4 is not parallel to each other, and same bending prism unit 4 has the first crooked curved surface 41a of extension and the second crooked curved surface 41b that extends of differently curved degree, so that different surface curvatures to be provided.By this, the first crooked curved surface 41a of extension and the first crooked curved surface 41b that extends can utilize different surfaces curvature guiding light tendency to produce the two dimension refraction, thereby promote the spotlight effect of bending prism unit 4 and whole concentration piece effectively relatively.
Please refer to Fig. 6 to shown in Figure 7, disclose the bending prism concentration piece of the utility model the 3rd embodiment.Compared to first embodiment, identical or different vertical height H of essence and horizontal width w can be selected to form in each two adjacent bending prism unit 4 of the 3rd embodiment, but the first crooked curved surface 41a of extension of each bending prism unit 4 and second crooked staggered brokenly respectively several lateral ridges 44a, the 44b of being convexly equipped with of curved surface 41b that extend.Each lateral ridge 44a, 44b are connected between crest line 42 and the trough conllinear 43, and each lateral ridge 44a, 44b form the continually varying surface curvature.Particularly, in the position of contiguous crest line 42 and trough conllinear 43, the surface curvature of lateral ridge 44a, 44b is tending towards smooth; In all the other positions away from crest line 42 and trough conllinear 43, lateral ridge 44a, 44b then are inclined to and form big surface curvature.By this, the first crooked curved surface 41a of extension and the second crooked curved surface 41b that extends can provide different surfaces curvature, produce the two dimension refraction with guiding light tendency, thereby promote the spotlight effect of bending prism unit 4 and whole concentration piece effectively relatively.Moreover each lateral ridge 44a, 44b can select to form identical or different surface curvature on demand.
Please refer to Fig. 8 and shown in Figure 9, disclose the bending prism concentration piece of the utility model the 4th embodiment.Compared to the 3rd embodiment, list on the first surface 31 of substrate 3 each two adjacent bending prism unit 4 of the 4th embodiment adjacent rows in parallel to each other, but each bending prism unit 4 has one extends a plane 41a ' and a crooked curved surface 41b that extends, crooked then staggered brokenly several lateral ridges 44b that is convexly equipped with of curved surface 41b that extends.Each lateral ridge 44b is connected between crest line 42 and the trough conllinear 43, and each lateral ridge 44b also forms the continually varying surface curvature.So, by the incident direction that incident light source (not illustrating among the figure) suitably is set, bending prism unit 4 still can utilize the crooked curved surface 41b that extends that different surfaces curvature is provided at least, therefore still bootable ray cast is extended curved surface 41b in this bending, and make the light tendency produce the two dimension refraction, thereby can promote the spotlight effect of bending prism unit 4 and whole concentration piece equally effectively relatively.Moreover each lateral ridge 44b can select to form identical or different surface curvature on demand.Identical or different vertical height H of essence and horizontal width w also can be selected to form in each two adjacent bending prism unit 4.
As mentioned above, the concentration piece of commonly using compared to Fig. 1 only has the one dimension refraction effect, or the concentration piece of commonly using of Fig. 2 limits shortcomings such as two dimension refraction efficient because of structure, the utility model of Fig. 4 forms irregular surface curvature by first and second crooked extension the in bending prism unit 4 on curved surface 41a, the 41b, really can promote whole two-dimentional light gathering efficiency, simplify the concentration piece structure, reduce folded line phenomenon and promote optics demonstration image quality.
