Opto-Mechatronics Integrated Design and Analysis for the Light Emitting Diode Projector

[[abstract]]本篇論文主要是在探討以發光二極體組成一維陣列，當投影機的光源並且投射出字幕影像系統之研製。光學成像部份以田口品質工程法設計最佳化參數並且由雙曲線反應法來輔助設計參數最佳化並且使影像看起來是清晰。 使用16 位元的微控制器和週邊電路，驅動一維發光二極體陣列，在投影機的光源設計裡。同時微控制器送出控制變頻器的訊號，來驅動無刷直流馬達。在機構方面，無刷直流馬達與六角柱體鏡面是互相結合的。因此，無刷直流馬達會帶動六角柱體鏡面旋轉。同時，六角柱體鏡面和一維發光二極體陣列也被同步驅動。據此，當六角柱鏡面旋轉時，會同步掃描出二維的影像。[[abstract]]This thesis mainly focuses on the image projection method of the projector by means of one-dimension light emitting diode (LED) array. The one-dimension LED array is the light source of the projector.Furthermore, in this thesis, the design of experiments such as Taguchi method or response surface methodology is employed to find out a set of optimum parameters of the optical design for showing a preferred image. In the light source design of the projector, the microprocessor with 16-bit and its peripheral circuits are employed to actuate the one-dimension LED light source. Meanwhile the microprocessor also sends the control signal to the inverter to drive the brushless DC motor (BLDCM). In the mechanism, the BLDCM and the hexa-pillar are assembled each other. Therefore, the hexa-pillar can rotate with the BLDCM. The hexa-pillar provides six mirrors around its circumference. Moreover,the one-dimension light emitting from the one-dimension LED array will be corresponded to the hexa-pillar.Accordingly, when rotating the hexa-pillar, the proposed method will provide a novel projecting method for converting the one-dimension light into two-dimension image so as to display the predetermined image, such that the cost of the projector system can be further reduced
