Abstract

A lighting apparatus comprising at least one light emitting diode is disposed on an interconnect board to emit ultraviolet or blue radiation. A polymeric layer including a luminophor is disposed about the lighting apparatus to convert at least a portion of the radiation emitted from the LED into visible light. The polymeric layer is shrinkable to conform to a shape enclosing the light emitting diode.
