Standards Development

Scope

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.

NOTE 5 Independent LED modules (see IEC 60050, 845-27-064) are considered as luminaires and will be covered by a future revision of IEC 62722-2-1: Luminaire performance - Part 2-1: Particular requirements - LED luminaires.

The lifetime of LED light sources is in most cases much longer than the practical test times. Consequently, verification of manufacturer’s lifetime claims cannot be made in a sufficiently confident way because projecting test data further in time is not fu lly reliable. For that reason the acceptance or rejection of a manufacturer's lifetime claim is out of the scope of this document.

Purpose

The first editions of the performance standards for LED light sources, IEC 62612 (LEDi lamps) and IEC 62717 (LED modules) are about 10 years old and, with the various amendments, worked reasonably well, especially in the early days of the transition to LED technology.

Looking at the current market, LED technology has evolved to a more mature level. Therefore, there is an increasing need for a standard for specifically LED light sources that incorporates the latest conventions and where test methods are practical and feasible to demonstrate that specified performance requirement can be met.

The development of a generic performance standard for LED light sources will replace the present LED light source performance standards which are related to only one LED light source type and improve coherency and simplify future maintenance.
