摘要

本論文係從光污染的角度切入，探討如何讓光可以有效地集中、侷限並均勻地照射到使用者所需要之目標區域內，以減少能量之損失、降低眩光之影響以及抑制光污染之生成，並且以此議題為出發點，藉由玻璃燒結式反覆縮模法搭配大面積翻印技術之方式，開發出一款具有高達89%之高穿透率以及光塑形效果的高性能表面結構擴散片，並以此表面結構擴散片做為核心元件，發展出兩款嶄新的高性能照明燈具，包括一光學效率高達87%以上、光學利用率介於58%至81%之間的高性能LED路燈，以及一兼具有快速光形調制效果和多種操作模態之智慧型照明燈具。除了高性能照明燈具之開發，本論文更以表面結構擴散片特性為基礎，將一具有與表面結構擴散片相同性能的結構散射片應用於全像光學儲存研究中，探討其對位移靈敏度以及能源效率之影響。

Aimed for reduction of light pollution and energy saving, this thesis focused on how to keep light effectively concentrated, limited, and uniform illuminated at a target region. By the motive, we proposed a novel way with high temperature down-size sintering technology and large-area impressing technology to perform a surface-structured diffuser with high transmission efficiency of 89%, obvious beam shaping effect, controllable divergence angle, and specific light pattern of uniform intensity distribution. Based on surface-structured diffuser, we proposed a novel concept of lighting module of street light with high optical efficiency which is higher than 87% and high optical utilization factor which is from 58% to 81%. Besides, we also proposed a novel intelligent lighting with a rapid optical-adjustable concept and multi-operated modes. Expect for high performance LED lighting, we also proposed a new way with use of a phase plate with micro-lens array to increase the shifting selectivity of hologram and to achieve higher energy efficiency in the application of holographic storage.
