Ta evropski standard določa zahteve za merjenje električnih, fotometričnih in kolorimetričnih količin svetilk LED, modulov, svetilnih mehanizmov in svetil za delovanje pri enosmerni ali izmenični napajalni napetosti, po možnosti s pripadajočo krmilno opremo. Fotometrične in kolorimetrične količine, zajete v tem standardu, vključujejo skupen svetlobni tok, svetlobno učinkovitost, delni svetlobni tok, porazdelitev svetilnosti, intenzivnost osrednjega žarka, svetilnost in porazdelitev svetilnosti, kromatske koordinate, korelirano temperaturo barve svetlobe (SCT), indeks barvne reprodukcije (CRI) in prostorsko kromatsko enotnost. Ta standard ne zajema paketov LED in izdelkov, ki temeljijo na diodah OLED (organske diode LED). OPOMBA: Kadar je uporabljen izraz »izdelek LED«, »naprava LED« ali »DUT« (naprava, ki se preskuša), ta zajema LED-sijalke, module, svetilne mehanizme ali svetila.

Introduction

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.

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) issued by IEC/TC 34/CLC/TC 34 “Lamps and related equipment” and/or relevant European

regulations.

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 European 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 document does not cover LED packages. Described measurement methods for LED lamp or

luminaires may apply as measurement methods for OLEDs products."
