Determining Two-Dimensional Phosphor Surface Temperature Distribution of Phosphor-Coated LEDs Based on Hyper-Spectral Imaging

We present a high-resolution non-contact method for the measurement of two-dimensional (2D) phosphor surface temperature distribution (PSTD) of phosphor-coated light-emitting diodes (pc-LEDs) based on advanced hyper-spectral imaging technology. The studied pc-LEDs with a surface-mounted device struc...
