IES LM-91 – Approved Method: Application Distance Radiometry
This document describes:
– The method for measuring illuminance, irradiance, and/or photon flux density at multiple points on a plane at a specific application distance
– A method to generate and interpret IES files composed of equivalent intensity values and
applicable only to a specific range of application distances
– The method for merging far-field characteristics with near-field characteristics at angles where points on the plane may be in the far field
This document covers the testing of lamps, light engines, and luminaires. It covers light source technologies such as LED, incandescent, fluorescent, HID, and OLED sources. This document does not cover batteryoperated light sources.
This document does not define methods for interpolating between measurement points on a given measurement plane, nor does it define interpolation methods between multiple measurement planes.
