Paper Abstract

Motivated by the growing number of applications the light emitting diodes, LEDs, are having in solid-state lighting systems, we summarize the new internationally standardized measurement methods for photometric and colorimetric quantities in LEDs; since they are commonly used to quantify some of the key performance parameters of several products used in automotive industry, traffic signaling, etc. Finally, special emphasis is given to the mismatch corrections factors calculation, and its use when measuring LEDs photometric and colorimetric quantities.
