Title: VOLUMETRIC LIGHT EMITTING DEVICE
Abstract:
A volumetric light emitting device (100) includes a substrate (112), a semiconductor light emitting diode (110) disposed on the substrate (112) and a reflector ring (114) extending axially from the substrate (112). The reflector ring (114) defines a first volume (124) bounded by the substrate (112), an inner wall (120) of the reflector ring (114), and a terminal plane (122) at a distal end of the reflector ring (114). An encapsulant (116) fills the first volume (124) and encapsulates the semiconductor light emitting diode (110). A volumetric light conversion element (118) surrounds the reflector ring (114) and the first volume (124) wherein the volumetric light conversion element (118) is adapted to down-convert light emitted from the semiconductor light emitting diode at a first wavelength (111) and emit the down-converted light at a second wavelength (113). A second volume (126) of encapsulant (116) or scattering material extends axially between the terminal plane (122) and the volumetric light conversion element (118).
