dc.description.abstract | 近年雷射照明最廣為人所知的應用即是高級轎車將遠光燈從LED改為雷射頭燈,相比現今最常見的LED,雷射技術的 最大優勢在於他的有效照射距離,其照射距離近乎能達到LED的兩倍,每瓦所能提供的照度相比LED也增加了約百分之七十,另外在電力耗損上,也比LED燈組低很多,因此雷射光源同時具有高效穩定的特點,在效能方面也勝過LED大燈。 本文的主軸是固態照明中,雷射白光光源的開發與應用。雷射技術的研發漸趨成熟我們首先分析了市面上主流的三款高瓦數藍光雷射,從中挑選最適合我們開發應用的雷射源,接著利用該雷射激發螢光體的光 源進行二次光學設計,其坐落在白光曲線上效率可以達到 220~233 lm/W。 在雷射光源投射系統上,探討穿透式的光機架構和反射式架構中之優缺點中,並利用雷射光源點光源特性,設計出高準直投射的光源系統。再加裝凹透鏡和X圓柱平凹透鏡的情形下,進行分析模擬,使其符合ECER112法規點要求之光強度和狹長型的照明範圍。 整合整本論文,第一部份先介紹雷射車燈的優劣勢和設計的方向,將雷射激發光源僅透過拋物面反射腔投射於接收面,觀察其光追跡情形和能量利用率;第二部分我們開發雷 射照明新的投射系統,呈現新的光路架構,並說明量測實驗方法及原理,彌補現今雷射車燈的缺失,並增加照射距離;第三部份透過螢光片的分析和散射方向和角度,利用在本文之光機系統,使色溫的分布能夠更均勻。最後在上述各章節之研究結果作整理,說明其解決的問題和帶來的優勢。 | zh_TW |
dc.description.abstract | In recent years, the most well-known application of radiation lighting is the high beam on the high-class car changed from LED to laser headlight. Compared with the LED headlight, the advantage of laser technology is its effective irradiation distance, which is two times as much as LED, and the illumination is also increased about 70% per watt. In addition, in terms of power consumption, it is much lower than the LED light system. Therefore, the laser light source is better than LED structure from the characteristics of high efficiency and stability. The main axis of this article is the development and application of white light source in SSD. The research and development of laser technology has gradually matured. In the beginning, this thesis analyzes the three high level blue laser, selects the one that is most suitable for our development and application, and then utilizes the light source as secondary optical design. Its efficiency on the white light curve is 220 - 233 lm/W. In the laser light source projection system, the advantages and disadvantages of the transmissive system and the reflective system have been discussed. This thesis uses the point light source characteristics of the radiating light source to design a highly collimated light source system. With the addition of concave lens and X cylindrical plano-concave lens, the illumination range meets the light intensity required by ECE R112. In this thesis, the first part introduces the design direction of the laser headlight and its strength and weakness. It projects the light source through the parabolic reflector cavity to the receiving surface in order to observe its light and energy utilization. In the second part, this thesis develops a new projection system for laser lighting, presents a new optical path architecture, and explains the measurement experiment methods and principles to settle the flaw of current laser headlights and longer the irradiation distance. In the third part, it analyzes the scattering direction and angle of the fluorescent sheet, and uses the optomechanical system to make the CCT distribution more uniform. Finally, it makes a summary on each paragraphs and explains the problems it solves and the benefits it brings | en |
