摘要

Dual paraboloidal reflectors (DPR) can couple more light into small etendue projection systems. The imaging property of DPRs at two conjugation focal points and their peripheral areas has been investigated using ASAP simulation and observation. The result confirms that the DPR can produce one to one image at the conjugated focal points, which is the reason why dual parabolic reflectors are beneficial. In the periphery area, the image is distorted. The image distortion was analyzed theoretically and the results agree with observation. This imaging property was used to develop a new method of locating the focal points of DPRs accurately. A new lamp manufacturing procedure and a pilot line were setup and tested. The coupled lumen efficiency has been increased by 13%.
