1. A lighting device, comprising:
- at least one solid state light emitter; and
at least first and second lumiphors, said second lumiphor comprising at least one luminescent material and at least one binder, said second lumiphor spaced from said first lumiphor, said first lumiphor in direct contact with said solid state light emitter, at least a portion of said first lumiphor between said solid state light emitter and said second lumiphor.

Abstract
A lighting device, comprising at least one solid state light emitter, at least one first lumiphor and at least one second lumiphor which is spaced from the first lumiphor. The solid state light emitter can be a light emitting diode. A method of making a lighting device, comprising positioning at least one second lumiphor spaced from and outside of at least one first lumiphor relative to at least one solid state light emitter. A method of lighting, comprising providing electricity to at least one solid state light emitter in such a lighting device.

16. A method of making a lighting device, comprising:
positioning a solid state light emitter, a first lumiphor, and a second lumiphor relative to one another such that said second lumiphor is spaced from said first lumiphor, said first lumiphor is in direct contact with said solid state light emitter, and at least a portion of said first lumiphor is located between said solid state light emitter and said second lumiphor, said second lumiphor comprising at least one luminescent material and at least one binder.

17. A method of lighting, comprising:
providing electricity to at least one solid state light emitter, whereby said solid state light emitter emits light, at least some of which passes through a first lumiphor, then through a second lumiphor, and then mixes with at least some light emitted from said second lumiphor, said first lumiphor spaced from said second lumiphor, at least a portion of said first lumiphor between said solid state light emitter and said second lumiphor, said second lumiphor comprising at least one luminescent material and at least one binder.

18. A lighting device, comprising:
-
at least one solid state light emitter; and at least first and second lumiphors, said second lumiphor comprising at least one luminescent material and at least one binder., said second lumiphor spaced from said first lumiphor, at least a portion of said first lumiphor between said solid state light emitter and said second lumiphor, wherein if said solid state light emitter is illuminated, at least some light emitted from said solid state light emitter would mix with at least some light emitted from said second lumiphor.
