|Orb Optronix LM-80 tester|
LM-80 testing is vital in the LED manufacturing space to document component performance. Moreover, LM-80 underlies the TM-21 method for predicting lumen maintenance. Orb Optronix recently announced the LM-80 Active Control Lifetime Test Chamber for what the company calls desktop testing of LEDs.
|Gigahertz-Optik LED measurement system|
Gigahertz-Optik, meanwhile, announced a single-pulse LED measurement system that can be used for binning of components for light output and color. The BTS256-LED tester and companion LPS-20-1500 power supply rely on a photodiode for accurate characterization of packaged or unpacked emitters. The device also includes a spectrometer for color measurement.
|Instrument Systems goniophotometer|
Moving to luminaire testing, Instrument Systems recently announced a new goniophotometer designed specifically for SSL applications. The LGS 250 was designed to analyze angle-dependent special radiation, and is suited for use with small to medium size LED retrofit lamps, luminaires, and modules.
The LGS 250 can take measurements in a range of +/- 160˚ on test units with a maximum diameter of 480 mm. You can combine the unit with a spectroradiometer to capture all spectral properties including chromaticity and color temperature. Moreover, Instrument Systems supplies the SpecWin Pro software to automate the collection and presentation of test data.
