LED’s technical characteristics’ testing system

The system is designed to measure the optical, electrical parameters, characteristics of the radiating sources, different displays, lighting panels and LEDs.

Overview

The system is designed to measure the optical, electrical parameters, characteristics of the radiating sources, different displays, lighting panels and LEDs.
Flexible hardware and software confguration supports highly automated measurements, analysis, temperature control and monitoring, compatability with and external optical measuring devices (radiometers, spectrometers, etc.) and different diameter of spheres.

Measurement types

Temperature:

  • Electrical and optical parameters dependency from temperature.

Optical:

  • Color, spectrum and spatial radiation pattern, effciency and radiated intensity, etc

Electrical:

  • IV characteristics (forward, reverse), pulsed sweep current measurement.

Opportunities

  • System auto-calibration;
  • LEDs massive measurement (128 pc.);
  • Precised control and temperature measure – 0.3°C, 8 channels;
  • Cold junction compensation;
  • DC power supply programmable:
    • Maximal voltage 200-500В;
    • Maximal current 2-5А;
    • etc.

Devices

  • NI PXIe 1082
  • NI PXIe 813x
  • NI PXIe 4353
  • NI PXIe 4065
  • NI PXI 2527
  • NI PXIe 6221
  • NI PXIe 4139

External optical measurement devices and sphere
The system custom develomment is possible for deployment in production.
