DANSK DSF/PREN IEC 63555 PDF

This document specifies performance requirements for LED light sources connected to a DC supply of up to 1 500 V or an AC supply of up to 1 000 V. This document specifies requirements and test methods for electrical, photometric, colorimetric and dimensional characteristics. NOTE 1 – LED light sources as defined in IEV 845-27-053 can take the form of an LED module or an LED lamp. This document covers LED light sources that produce light with a correlated colour temperature typically between 2 200 and 6 500 K, based on inorganic LED technology. NOTE 2 – Correlated colour temperature is a quantity used to describe the chromaticity appearance of a light source emitting white light. NOTE 3 – The scope is not limiting for values outside the mentioned CCT range. Therefore, the addition of the word “typically” is important. The CCT preferred values used in this document are specified in Annex C. NOTE 4 – See the definition of correlated colour temperature in IEC 60050 -845:2020, 845-23-068. The requirements of this document relate only to type testing. This document does not apply to: – LED packages; – LED light sources for automotive lighting; – LED light sources for horticultural lighting; – OLED light sources.
