STIMULATED LIGHTING DEVICES
First Claim
1. A stimulated lighting device comprising:
- a luminescent sheet including light stimulatable particles configured to emit secondary light upon receiving primary light;
a source configured to generate and direct said 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;
a light exit configured to emanate light from the lighting device as a combination of the primary light and the secondary light.

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.
