1 Scope
This part of IEC 62722 specifies the performance requirements for LED luminaires, together with the test methods and conditions. It applies to LED luminaires for general lighting purposes.
Semi-luminaires are not covered under the scope of this document.
For some types of luminaires (e.g. decorative or household) the provision of performance data under the scope of this document is not appropriate.
In this document, the following types of LED luminaires are distinguished.
Luminaires using an LED lamp are covered in IEC 62722‑1 and are not within the scope of this document.
The requirements of this document relate to type testing.
This document covers LED luminaires using LED modules, based on inorganic LED technology that produces white light. It does not cover luminaires using light sources based on OLED technology (organic LED technology).
The lifetime of LED luminaires is in most cases much longer than the practical test times. Consequently, the verification of manufacturer’s lifetime claims is out of the scope of this document.
Instead of lifetime validation, this document has opted for lumen maintenance categories at a defined finite test time. Therefore, the category number does not imply a prediction of achievable lifetime. The categories are lumen-depreciation character categories showing behaviour in agreement with the manufacturer’s information which is provided before the test is started.
A Commented Version (CMV) of this standard is available here. Please note, the CMV of the standard is not adopted, and therefore doesn’t contain an additional national foreword, or national annex that might be contained in the BS adoption of the standard. However the IEC text that forms the content of the standard is identical to the BS adoption of the standard.
Commented Versions (CMVs) are specialized publications featuring detailed commentary from technical experts on the major changes between the new edition of a standard and the previous one. Comments may include an explanation for the changes as well as information on the impact of these changes on the application and usability of the standard.
