Edition Date: 18/11/2009 This document covers the LED part which is an integral part of the luminaire or other lighting equipment operating in the range of 400-700nm.These requirements also cover the component parts of light emitting diode (LED) equipment, including LED drivers, controllers, arrays, modules, and packages as defined within this standard.

IES LM-82-12: Characterization of LED Light Engines and LED Lamps for Electrical and Photometric Properties as a Function of Temperature

Organization: The Illuminating Engineering Society of North America (IESNA). Edition Date: 13/02/2012 The new standard is designed to establish consistent methods of testing and data presentation to assist luminaire manufacturers in selecting LED light engines and integrated lamps for their luminaire products. This approved laboratory method defines the procedures to quantify the performance of LED light engines and integrated LED lamps as a function of temperature.

JESD 51-51: Implementation of the Electrical Test Method for the Measurement of Real Thermal Resistance and Impedance of Light Emitting Diodes with Exposed Cooling

Organization: JEDEC Solid State Technology Association Edition Date: 12/04/2012 This document provides information on thermal test requirements (static test methods) for the measurement of real thermal resistance and impedance of LED (Power LED’s and High brightness LED’s) with exposed cooling surface. The purpose of this document is to specify, how LEDs's thermal metrics and other thermally-related data are best identified by physical measurements using well established testing procedures defined for thermal testing of packaged semiconductor devices (published and maintained by JEDEC) and defined for characterization of light sources (published and maintained by CIE – the International Commission on Illumination).

IES LM-80-08: LED Lumen Maintenanceof LED Light Sources

Organization: The Illuminating Engineering Society of North America (IESNA) Edition Date: 22/09/2008 The purpose of LM-80-08 is to allow a reliable comparison of test results among laboratories by establishing uniform test methods. It addresses the measurement of lumen maintenance testing for LED light sources including LED packages, arrays and modules only. It does not provide guidance or recommendations regarding prediction estimations or extrapolations for lumen maintenance beyond the limits of the lumen maintenances determined from actual measurements.
