Analytical/Experimental Hybrid Approach Based on Spectral Power Distribution for Quantitative Degradation Analysis of Phosphor Converted LED


Lumen depreciation and color quality change of phosphor-converted LED (pc-LED) are caused by the combination of various degradation mechanisms including chip, phosphor layer, and packaging material degradations. We present an analytical/experimental hybrid procedure to quantify the effect of each mechanism on pc-LED degradation. A mathematical model based… (More)
