Introduction:

EVERFINE provides the professional test and measurement instruments for all kinds of packaged LEDs (SMD, COB, etc.). The quantities include spectrum, luminous flux, chromaticity coordinate, CCT, CRI, luminous intensity, color nonuniformity, radiation safety and so on, and full meet the requirement of CIE 127-2007, LM-79-08, LM-80-08, LM-85-14, IEC62471, etc..


For small & middle power LEDs

 

For high power LEDs and COB LEDs

 

1. Shere spectroradiometer systems
Measure Luminous Flux, Luminous efficacy, radiant power, Spectral Power Distribution, Chromaticity Coordinate, Correlated Color Temperature, Peak Wavelength, Dominant Wavelength, Spectral Half Width, Color Rendering Index, Colorimetric Purity, red ratio, Standard deviation of color matching(SDCM), forward voltage, forward current, reverse voltage, reverse current etc.Equipped with HAAS series High Accuracy Array Spectroradiometer and suitable Programmable Power Supply & Power Meter, the system can realize both pulse measurement and stable measurement for spectral & Colorimetric & optical & electrical characteristics of LEDs. Equipped with temperature controller, the system can realize meausrement in specified case temperature or junction temperatures.

2. Luminous Intensity Distribution/Beam Angle Test System
Measure luminous intensity, luminous intensity distribution, In- IF curve, IF-VF curve, time characteristics of (averaged) luminous intensity, spread angle of light beam, luminous flux,forward voltage, forward current, reverse voltage, and reverse current etc.
Equipped with a spectroradiometer, the system can measure the spatial color distribution and the uniformity.
For small power LEDs, we have the system to meet the requirement of CIE 127.
For high power LEDs, a much longer measurement distance is required, the GO-Spex100 or GO-I300 is recommended.

3. Aging & Life & Lumen Maintenance Test System
The systems are widely used for normal /accelerated aging, lumen maintenance measuring, lifetime evaluation and temperature characteristic testing for LED packages, arrays, and modules. The test items include photometric quantities vs. time (lumen maintenance), photometric quantities vs. case temperature(temperature characteristics), colorimetric quantities vs. case temperature(temperature characteristics), forward voltage vs. time, forward voltage vs. photometric quantities, forward voltage vs. colorimetric quantities, and etc.. The extrapolation of lifetime by programmable models is also available to estimate the lifetime of LED products.The systems fully meet the requirement of IESNA LM-80-2008, IES TM-21, ENERGY STAR and other related international and Chinese standards.
