First Claim
1. A lighting device, comprising:
- a first group of solid state light emitters; and
at least a first luminescent material,wherein;
at least some of said first group of solid state light emitters are in a first group of packages, each of which also comprises at least some of said first luminescent material;

, v′
color coordinates on a 1976 CIE, Chromaticity Diagram which define a first point; and
if said first group of solid state light emitters which are in said first group of packages are illuminated, at least 20% of said first group of packages would emit light having u′
, v′
color coordinates on a 1976 CIE Chromaticity Diagram which define respective points which are each spaced from said first point by a distance of not less than 0.10 and not more than 0.30.

Abstract
A lighting device, comprising a first group of solid state light emitters and a first group of lumiphors, wherein at least some of the first group of solid state light emitters are contained in a first group of packages, each of which also comprises at least one of the first group of lumiphors. If all of the first group of solid state light emitters which are contained in the first group of packages are illuminated and/or if current is supplied to a power line, (1) a combined illumination from the first group of packages would, in the absence of any additional light, have color coordinates on a 1976 CIE Chromaticity Diagram which define a first point, and (2) at least 20% of the packages would emit light having color coordinates spaced from the first point. Also, methods of lighting.
