In order to determine how long LEDs will last or how a luminaire will survive in wet weather, there many tests they go through. Here is a general list of the types of tests that LED chips, lamps and luminaires can go through.
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)
To describe the procedures in performing reproducible measurements of LED light engines and integrated LED lamps, at any given temperature for the performance characteristics (total luminous flux, electrical power, etc.)
To provide safety requirements for LED equipment that is an integral part of a luminaire or other equipment and which operates in the visible light spectrum between 400 – 700 nm.
The requirements also covers the component parts of the light emitting diode (LED) equipment, including LED drivers, controllers, arrays, modules, and packages as defined within this standard.
