Implementation of Led Projector
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
there are two parts of projector according to their desired characteristics. One of them brightness system it composes blue, green and red leds. Each of them has collimator diachronic filter collimated by dichronic filter it combine three wavelength lights together the last part is condenser the micro-lens array and tir prism is used to reduce the size of illumination system and illuminate dmd uniformly. The one is imaging system. According to the standard of dmd; the effective focal length, angle of view , the imaging quality of lens and the relationship of imaging and object can be defined. By using optical simulation software, code v and zemax, the lens conform to the standards was well designed. Finally the meekness of production was analysed. In this design, the normal light efficiency of three wavelengths led on dmd is 51.13%, and the normal uniformity on dmd is 95.17%. Approximately the screen, the normal light efficiency is 44%, and the normal uniformity is 87.3%.
