Paper Abstract

Based upon the principles of non-imaging optics, we present new optical designs for illumination devices (luminaries) that can achieve maximal lighting efficiency (no trapped radiation) while retaining excellent angular control of the projected radiation. One class of luminaries presented can produce relatively uniform flux maps on distant targets while also insuring perfectly sharp (discontinuous) angular cutoffs. For a second class of luminaries, for which pair-overlap flux maps are to be exploited and the flux maps of individual devices have sloping shoulders, we can produce extremely uniform flux maps on distant targets while retaining excellent angular (glare) control. Results are presented for symmetrical configurations in two dimensions (trough-like reflectors) for flat and for tubular sources. Primary applications can include lighting and infrared heating.
