Test Method for LED Lamps, LED Luminaires and LED Modules
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 devices 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 declared
measurement uncertainty) and comparison of different products on
the same basis is possible.
The 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 standard does not cover LED packages and products based on
OLEDs (organic LEDs).
The 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 issued
by IEC/TC 34 "Lamps and related equipment".
As LED devices offer a large variety of configurations
in respect to geometry and/or colour, the photometric and colorimetric
performances are considered individually for each configuration.
