Abstract
A light emitting device can include a substrate with LED chips disposed on a surface of the substrate. The LED chips can include chips of at least four different colors. Electrical paths disposed in part on the substrate and in part within the substrate can connect the LED chips into at least three independently addressable groups, and the number of independently addressable groups can be less than the number of colors of LED chips, so that at least one of the groups includes LED chips of two or more different colors.
