Abstract: A wavelength-conversion plate is described herein. The wavelength conversion plate may include a converter of a first ceramic material and a reflector of a second ceramic material. The first ceramic material converts the primary light emitted by a light source such as a light emitting diode (LED) into a secondary light and the second ceramic material reflects the secondary light emitted by said converter. Preferably, the converter is inlaid into the reflector so that the reflector surrounds an outer edge of the converter. Such a configuration has an advantage of reducing unwanted side emissions from the converter.

Abstract: White-light efficiency from a light emitting diode is enhanced by recycling outwardly inwardly-penetrating light by application of a multi-layer, thin film filter between the LED die and the phosphor layer. This procedure increases the package extraction efficiency.
