How are LEDs tested?
Provide procedures for reproducible measurements of photometry, color and electrical characteristics of SSL products.
What can be tested with this standard?
Total luminous flux
Zonal lumen summation
CCT (Correlated Color Temperature)
CRI (Color Rendering Index)
Chromaticity Coordinates (x,y and u’,v’)
Spatial uniformity of color
Provide methods of the measurement of lumen maintenance of LED packages, arrays and modules.
Provide a calculation tool to interpret the data collected from LM-80 testing; to provide users with lumen maintenance life (e.g., L70) projection, or to predict estimated lumen output values at a given time duration; to interpolate lumen maintenance behaviors for the in-situ temperature (different from testing temperature)
