Overview
This European Standard specifies the requirements for measurement of electrical, photometric, and colorimetric quantities of LED lamps, LED modules and LED luminaires, for operation with AC or DC supply voltages, possibly with associated LED control gear. LED light engines are assimilated to LED modules and handled accordingly. Photometric and colorimetric quantities covered in this standard include total luminous flux, luminous efficacy, partial luminous flux, luminous intensity distribution, centre-beam intensity, luminance and luminance distribution, chromaticity coordinates, correlated colour temperature (CCT), colour rendering index (CRI), and angular colour uniformity. This European Standard does not cover LED packages and products based on OLEDs (organic LEDs). This document (EN 13032-4:2015) has been prepared by Working Group WG 7 "Photometry" of Technical Committee CEN/TC 169 "Light and lighting", the secretariat of which is held by DIN (Germany). The German standardization committee responsible for this standard is NA 058-00-03 AA "Photometrie" ("Photometry") at DIN.
