Abstract

The feasibility of applying multiple white organic light-emitting diodes (WOLED) to establish specific planar illuminative patterns for general lighting without secondary optical components was experimentally investigated in smaller scale by using a single-axis automatic optical measuring system. Regular white light-emitting diodes (WLED) usually require secondary optical components to transform its point-source optical characteristics into specific planar illuminative pattern for general lighting application. WOLED has become a potential planar lighting source due to its unique device structure. The lighting source in our experiment consists of three WOLED's mounted side-by-side with changeable tilting angle. This adjustable lighting source with three planar WOLED's may be feasible for forming required illuminative pattern without using secondary optical components. Our preliminary experimental result measured from a 3-WOLED source with specific tilting angle in smaller scale suggests that a relatively uniform illuminative area can be established in practical mean without secondary optical components.
