碩士 === 國立高雄應用科技大學 === 電機工程系 === 100 === This study focused on phototherapy optical system design and development, we use the parabolic reflector to change LED light shift for parallel light, Improve the shortcomings of the phototherapy, when it uses the distance increases the face illumination is lower. we use the elliptical reflector to collect the LED sidelight and make convergence another focus of the ellipse and then use the mirror reflected back the collect light to the parabolic reflector, increase the light use efficiency and improve facial illumination uniformity.
