本論文研究與設計一盞完整特殊光譜燈具,作為動植物生長所需。我們從探討光源波長之選用開始,進行燈具之光形與散熱之研究。為使本燈具具有量產的可行性,我們也進行燈殼之設計,並提出一套製作流程。在模擬設計中,我們分析線陣列、面陣列以及同心圓陣列此三種光源陣列分布方式的優缺點。我們以六盞實驗燈具置於特殊長寬高與水深為24 cm之水缸體上方,並在距離光源幾個特殊距離上,分析光形分布及其照度。我們在最後製作一盞燈具成品並進行設計的驗證。;In this thesis, we studied and designed a luminaire with specific spectrum for plant growth or others. We started from selecting light source with specific wavelength, and then design the required light pattern and study thermal dissipation. In considering the mass production, we designed the housing structure, and proposed a manufacture process. In the optical simulation, we analyzed the geometry for light source location, including line, plane and concentric shapes. We made six luminaires, and put them at different distances above the surface of the water tank, where the depth of the water was 24 cm. We studied the light distribution and illuminance across the water tank. Finally, we made a well-finished luminaire to verify the design.
