Henry J. Meyer,Robert R. Alfano, drive current, temperature, and moisture. The degradation of LEDs can be attributed to either the GaN chip itself or the LED package. In this chapter, we will focus only on the package degradation due to the operating conditions..In view of the general packaging structure of high power LEDs, this

Color Rendering Metrics: Status, Methods, and Future Development,or dulling) and clash with the subjective preferences to the color quality of illumination. Supplementing these conventional measures with additional figures of merit accounting for the gamut area of a small number of the test color samples does not completely address this issue. The color rendition
