Title:
WAVELENGTH-CONVERTING LIGHT-EMITTING DEVICES
Document Type and Number:
WIPO Patent Application WO2007040627
Kind Code:
A8
Abstract:
A light-emitting device is provided. The device may include a thermally conductive region in contact with a wavelength-converting region (e.g., a phosphor region). The thermally conductive region may aid in the extraction of heat resulting 5 from light absorption in the wavelength-converting region, which, if excessive, may impair device operation. The presence of a thermally conductive region can enable devices including wavelength-converting regions to operate even at high power levels (e.g., light generated by the light-generating region and/or by the light-emitting devic having a total power greater than 0.5 Watts) for long operating lifetimes (e.g., greater 10 than 2,000 hours).
