LIGHTING DEVICE
First Claim
1. A lighting device comprising:
- at least first and second solid state light emitters;
at least one luminescent element, the luminescent element comprising at least one luminescent material, the luminescent element being spaced from the each of the first and second solid state light emitters,wherein the first solid state light emitter emits light of a first wavelength, the second solid state light emitter emits light of a second wavelength, and the first wavelength differs from the second wavelength.

Abstract
A lighting device comprising at least one solid state light emitter and at least one luminescent element spaced from the light emitter, a surface of the luminescent element being at least twice as large as the illumination surface of the light emitter. Also, a lighting device comprising at least one solid state light emitter and at least one luminescent element spaced from the light emitter, a surface of the luminescent element surface being at least twice as large as and substantially parallel to the illumination surface of the light emitter. Also, a lighting device comprising at least one solid state light emitter and at least one luminescent element spaced from the light emitter, a surface area of a projection of the luminescent element being at least twice as large as a surface area of a projection of the light emitter.
