Light emitting panel

A light emitting panel 10 includes a base panel 12 and light emitting elements 14 mounted to the base panel 12. Each of the light emitting elements 14 produces an illumination pattern having a region of substantially uniform intensity that extends over a radiation angle of at least 60{ and preferabl...

Zusammenfassung:	A light emitting panel 10 includes a base panel 12 and light emitting elements 14 mounted to the base panel 12. Each of the light emitting elements 14 produces an illumination pattern having a region of substantially uniform intensity that extends over a radiation angle of at least 60{ and preferably at least 100{. One or more light conditioners, preferably comprising a diffuser 16 and a brightness enhancer 18, are positioned adjacent the base panel 12 to receive and condition the light produced. Each light emitting element 14 is ideally an LED comprised of a light emitting junction (34), mounted in a reflector cup (32) with a lens (36) positioned over the cup (32). The lens may be substantially flat (36) or comprise a concave and a convex portion (136).
