頂部出光均勻二次透鏡利用一碗形結構的透鏡底座與透鏡陣列來使得不同的高功率LED集中能量於頂部出光;其中透鏡底座讓側面出光經由此透鏡底座後全反射向頂部出光,而透鏡陣列則是用來調整向頂部出光的光線出光的角度與均勻性。
側面出光二次光學透鏡首先改良頂部出光均勻二次透鏡的透鏡底座最下緣改為垂直,並控制調整頂部與側面出光的比例;之後再將改良範圍向上延伸,增加側面出光的比例並控制在一定的角度範圍內減少頂部出光的能量。
摘要(英) The main objective of this thesis is to design the module of secondary optical lens for the light source of high power LED. Three different types of high power LED were utilized for the designs of uniform top-emitting and side-emitting secondary optical lens. The optimum results can be reached with the most localized optimization in the ranges of specified conditions.
The bowl-shaped lens pedestal and lens array are used in the uniform top-emitting secondary optical lens to make different high power LEDs to concentrate the energy on emitting light on the top. The side emitting light are totally internal reflected by the pedestal lens and emitted light on the top. The lens array can adjust the light angle and uniformity of the emitting light on the top.
Firstly, the side-emitting secondary optical lens can be improved with the vertical bottom edge of the uniform top-emitting secondary optical lens. The emitting ratio between top- and side- emitting light will be well controlled and adjusted at the same time. After then, the improved ranges were extended and the portion of side-emitting light was increased and well controlled within the range of certain angle to reduce energy of the light on the top.
