Abstract
Remote phosphor LED light source is widely used because of its special efficient optical characteristics. However, in contrast to the performance of traditional led light source, the available research work on its supporting optical systems is insufficient. Here we report a two component optical system comprising remote phosphor LED light source and reflective secondary optical element, and the spatial light intensity distribution of r emote phosphor LED by a near field photometer was fully taken into account in our design. Compared with the traditional LED industrial lamp, the Unified Glare Rating (UGR) of the industrial lamp is reduced from 19 to 16, and the uniformity of illumination is increased from 0.7 to 0.8..
