| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an optical device of a lamp cover, capable of reducing glaring light while improving brightness.SOLUTION: An optical device 10 of a lamp cover is made of a transparent plastic material. The optical device 10 includes a smooth light incident surface 100 and a smooth light emission surface 101 provided opposite the light incident surface 100. The light emission surface 101 is provided with a plurality of micro fence components 11 whose cross section appears in an inverse trapezoidal shape. The micro fence components 11 generate circulatable circulation light, and the circulation light is emitted by being matched with light emitted from a light source 20. The micro fence components condense light into a center by compensation of lateral light in the circulation light, and reduces a phenomenon of glaring light while improving brightness.SELECTED DRAWING: Figure 4
【課題】輝度を向上しながら眩光を低減できるランプカバーのオプティカルディバイスを提供する。【解決手段】透明のプラスチック材料から構成されるランプカバーのオプティカルディバイス１０であって、オプティカルディバイス１０は、滑らかな光入射面１００と、光入射面１００と反対的に設けられる滑らかな光出射面１０１を有する。光出射面１０１には、断面が逆の台形に現れる複数のマイクロ柵構成１１が設けられる。これらのマイクロ柵構成１１は、循環可能の循環光が発生され、この循環光が光源２０から発生する光と整合して射出され、循環光における側方向の光の相殺により、光を中央に集中し、輝度を向上しながら眩光の現象を低減する。【選択図】図４ |
