Solid state (e.g., LED) lighting devices include multiple emitters mounted on or over a substrate comprising Insulating material with conductive traces thereon, with various emitters being independently controllable with multiple pairs of anodes and cathodes that may be arranged on an opposite surface of the substrate than the emitters. Electrically conductive vias may be defined through the insulating substrate, and a molded lens may be provided over the substrate and emitters mounted thereon. Various combinations of independently controllable emitters or emitter groups may be provided, for example, a red emitter in combination with multiple blue shifted yellow (BSY) emitters, or separately controllable red, green, blue, and white (e.g., BSY) emitters. |
