Abstract :
In this study, we report in protons radiations damages on Europeans manufactured Commercial Of The Shelf (COTS) Light Emitting Diodes (LED). The aim of this study was to assess the potentiality of such devices for space applications. In total, fifteen references coming from three different manufacturers have been tested. All devices have been stepirradiated with 50 MeV protons, up to a fluence of 2.5 1012 protons/cm2. Light output, I-V characteristics and emission spectra were measured.
