19、oduction This standard provides requirements to perform reproducible photometric and colorimetric measurements on LED lamps, LED modules, and LED luminaires (LED devices). It also provides advice for the reporting of the data. The availability of reliable and accurate photometric data for LED device

20、s is a basic requirement for designing good lighting systems and evaluating performance of products. By obtaining these data through measurements in specific normalized measuring conditions, the consistency of the data should be ensured between different laboratories (within the limits of the declar

21、ed measurement uncertainty) and comparison of different products on the same basis is possible. This standard aims in particular to cover measurement methods for testing the compliance of LED devices with the photometric and colorimetric requirements of LED performance standards (see Clause 2) issue

22、d by IEC/TC 34 “Lamps and related equipment”. LED devices offer a large variety of configurations in respect to geometry and/or colour. For each configuration the photometric and colorimetric performances are considered individually. 1 Scope This standard specifies the requirements for measurement o

23、f 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 quantiti

24、es 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 co

25、lour uniformity. This standard does not cover LED packages and products based on OLEDs (organic LEDs). 2 Normative References The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.1For dated references, only the edition ci
