Abstract
The last decade has seen extensive development in the design and application of 'remote source' lighting systems in which light is transmitted by a transport device before being emitted at a remote location. This note is concerned with 'discrete' remote source emitters which operate in a manner similar to conventional luminaires to distribute light delivered by the transport system. Two types of discrete emitter for specialist application are commercially available but the majority of emitter designs in the literature are conceptual only. This paper reports photometric measurements on prototypes of some published conceptual designs of discrete emitter. The results indicate likely efficiencies and light distributions from such devices.
