Abstract

A plurality of organic light emitting diode (OLED) devices can be spatially distributed to form various lighting systems and luminaires. The lighting systems can be configured to readily replace conventional light bulbs or tubular fluorescent lamps. A networked lighting system including a plurality of OLED devices can have a variable light field based on a feedback.
