Illumination System using Two Lamps for the Projector

摘要

In this paper, an illumination system design using two lamps was proposed to improve the brightness of the projector. The proposal is based on the results from optical simulation.The prism array was applied to maintain the same optical properties, such as brightness distribution for the divergence angle and the composed beam size of the system. These were compared to those of the one UHP lamp system. The brightness of the two-lamp system, having a panel size of 0.74' and an f/2.9, increased by a factor of 1.7 when compared to the brightness of one UHP lamp system.
