Bentham manufactures a system for batch testing LEDs. Each carrier board accomondates up to 50 devices. A universal mounting socket has been developed to suit nearly all LED device packages currently supplied. A single keystroke enables full optical and electrical characterisation of each device with seamless integration with database and analysis software. The modular drive electronics are most commonly supplied with programmable forward current, If, and reverse voltage, Vr, power supply. The system records for each device:

  • full spectral distribution
  • averaged intensity, ILED B
  • peak wavelength and bandwidth
  • dominant wavelength
  • chromaticity co-ordinates
  • colour purity and CRIs
  • forward voltage, Vf
  • reverse current, Ir
