摘要： Phosphor converted white LEDs (pc-WLED) with different geometries, namely remote-dome, remote-plate, half-dome, and conformal-coating packages, were studied using simulations to obtain the thermal power and the temperature distribution. The results of an experiment carried out to measure the temperature distribution in these pc-WLEDs validate the simulation results. A hotspot always occurs in the phosphor region. The conformal-coating package is the most feasible choice to reduce the hotspot temperature comparing with the other geometries. 其他題名： Opt Express 出版者： United States 出版日期： 2015-12-28 出處： Optics express, 2015-12, Vol.23 (26), p.33861-33869 資源來源： Optica Publishing Group (Optics Infobase) 識別號： ISSN: 1094-4087 識別號： EISSN: 1094-4087 識別號： DOI: 10.1364/OE.23.033861 識別號： PMID: 26832046
