Industrial Luminaires Measurement

Ophir FluxGage FG1500 features an aperture size of 144 x 64cm, allowing for photometric measurement of large-size street and industrial luminaires, LED flat panels, and troffer lights. Photometric measurements include total luminous flux (up to 80,000 lm), spectrum and color parameters (CCT, CRI, TM-30), and flicker.

The FluxGage FG1500 performs fast, photometric measurements in 2? (two pi) geometry. This allows for quick and accurate quality control where measurements of the complete, assembled, large-size LED systems are needed, both during development and directly at the end-of-line in luminaire production.

The FluxGage system uses solar panels as light detectors. The panels are arranged on the inside walls of the measurement cavity and are covered with a special black plastic layer with hundreds of transparent pinholes, creating the effect of many tiny radiometers. This design significantly reduces the reflectance of the solar panels, creating a measurement system resembling a goniophotometer in a dark room. Unlike an integrating sphere, the FluxGage is insensitive to reflections going back and forth between the measurement device and the luminaire under test.

The FluxGage system incorporates a spectrometer for measuring spectral flux and other color parameters (CCT: correlated color temperature, CRI: color rendering index, TM-30-15: fidelity and gamut index, Duv, and chromaticity). A fast photodiode sensor is used for measuring flicker.

Integrated application software simplifies set up and operation; all of the photometric data of the light source is displayed. The FG1500 connects to a PC via a USB cable. The Ophir FGC100, a NIST-traceable, broadband LED calibration standard, is used for periodic calibration of the FluxGage system.
