Abstract

A light emitting device provides a light emitting diode 6 comprising a light emitting layer, which produces non-white light, and a sapphire substrate interposed between the light emitting layer and a light conversion layer 5 to convert light emitted by the LED into apparently white-light. The light emitting layer may comprise GaN, InGaAs or GaAlN emitting blue or UV light, and the conversion layer may contain a scattering medium and a fluorescent material containing one or more phosphors. A reflector such as a diffuser, scatter plate, lens or mirror may be placed above or below the LED, and an optical mechanical device such as a lens array or binary optics device may be included between the conversion layer and the reflector.
