The method will provide a projected lifetime for the LED source or system.

Although constant current control is typical for stand alone LEDs, this document deals with integrated SSL products incorporating iesna lm-79-08 semiconductor device level current control, thus the electrical parameters of interest are the Om-79-08 product’s input electrical iesna lm-79-08.

Among other thing, TM will consider: This approved method describes the procedures to be followed iesna lm-79-08 precautions to be observed in performing reproducible measurements iesnw total luminous flux, electrical power, luminous intensity distribution, and chromaticity, of solid-state lighting SSL products for illumination purposes, under standard conditions. Additional information Weight 1 lm-7908 Dimensions 11 x 8.

This document describes test methods for individual SSL products, and does not cover the determination of the performance rating of products, in which individual variations among the products should be considered.

The results can then be used to interpolate the lifetime of iesna lm-79-08 LED source within a system luminaire or integrated lamp using the in-situ LED source case temperature. SSL products as defined in this document utilize LEDs including inorganic and organic LEDs as the optical radiation sources to generate light for illumination purposes. Only iesna lm-79-08 from recognized laboratories are relevant. Thank you for you patience.

Where this is done, such results are meaningful only for the particular conditions under which they were obtained iesna lm-79-08 these conditions shall be stated in the test report.

Iesnna Description This iesna lm-79-08 method describes the procedures to be followed and precautions to be observed in performing reproducible measurements of total luminous flux, electrical power, luminous intensity distribution, and chromaticity, of solid-state lighting SSL products for illumination purposes, under standard conditions.

This document does not cover SSL products that require external operating circuits or external heat sinks e. This approved method covers LED-based SSL products with control electronics iesna lm-79-08 heat sinks iesna lm-79-08, that is, those devices that require only AC mains power or a DC voltage power supply to operate. It is then the basis for lifetime interpolation either based on TM or other method. An LED is a p-n junction semiconductor device that emits incoherent optical radiation when biased in the forward direction.

Electrical and Photometric Measurements of Solid-State Lighting Products

For the purpose of iesna lm-79-08 approved method, the determination of these data will be considered photometric measurements. For LED luminaire we consider L70 to be the standard. This iesna lm-79-08 method covers LED-based SSL products with control electronics and heat sinks incorporated, that is, those devices that require only AC mains power or a DC voltage power supply to operate.

Lmm-79-08 is iesna lm-79-08 at the request of the publisher, as it helps them protect their copyright by restricting file sharing. Besides, the lumen maintenance, the chromaticity shifts over the measured period. For special iesna lm-79-08, it may be useful to determine the characteristics of SSL products when they are operated at other than the standard conditions described in this approved method.

Softcover or Digital PDF: This document covers Iesnna products in a form of luminaires fixtures incorporating light sources as well as integrated LED iesna lm-79-08 see section 1. Life notation results will then use the iesna lm-79-08 standardized nomenclature: The measurement has to be performed according to the temperature measurement point TMP indicated by the LED package manufacturer.

This document does not cover fixtures designed for SSL products sold without a light source.
