Abstract:	本計畫主要為開發一種新型透鏡式LED手術燈具，此手術燈具具有低眩光、高效率、環保、節能、可調照明區域範圍大小等特徵，且符合國際手術用照明燈具的標準。本計劃擬建立的光學設計技術的主要步驟：1. 藉由光場演算設計技術，有效率的設計較佳化的燈具；2. 利用低擴散度的擴散片將直接眩光的光線散開以降低眩光值，並且經由改變擴散片的霧度或數量，達到可調變目標區域的照明區域範圍大小的功能，此外擴散片也可將色溫均勻度有效的提升，減低手術時的傷害；3. 考慮在透鏡外增加眩光吸收環片，以吸收直接眩光，使得眩光的影響更為減少，且可做為擴散片的支撐。本計劃擬開發的手術燈，除了保留透鏡式手術燈優勢，還改良存在的缺點，設計一款更具優勢的手術燈。 ;The goal of this project is to develop a new type of lenticular LED surgical lamps which is low glare, high efficiency, environmentally friendly, energy-saving and provided with adjustable illumination area range, also meets the standards of international surgical light standard. The main steps of the optical design technology established by this plan are: 1. Efficiently design better luminaires by optical field calculation design technology; 2. Using low haze diffusion sheets to spread the direct glare to reduce glare value. And by changing the haze or the amount of the diffusion sheets to achieve the function of adjustable target area illumination area range size. The diffusion sheet can also effectively increase the uniformity of the color temperature and reduce the injury during surgery. 3. Considering adding a glare absorbed sheet to directly absord glare to reduce the influence of glare. The surgical lamps developed by this project retain the advantages of lenticular surgical lamps also improve the existent disadvantage .
