Abstract
A stimulated lighting device for stimulatable light emission including a luminescent sheet including light stimulatable particles which emit secondary light upon receiving primary light. The lighting device includes a source configured to generate and direct the primary light obliquely onto the luminescent sheet, at least one reflector configured to reflect at least a part of the primary light and a part of the secondary light onto the luminescent sheet and configured to reflect at least a part of scattered primary light and a part of the secondary light from the luminescent sheet toward the light exit, and a light exit configured to emanate light as a combination of the primary light and the secondary light.
