DOI: 10.1109/ted.2018.2890193
Abstract: We propose a transmission-type measurement system for determining temperature-dependent optical characteristics (TDOCs) for phosphors or remote phosphor plateswhich are applied in high-powerwhite light-emitting diodes, related to their stabilities and reliabilities. The proposed measurement system possesses… read more here.
