  An irradiation campaign was conducted to provide guidance in the selection of
materials and components for the radiation hardening of LED lights for use in
CERN accelerator tunnels. This work describes the effects of gamma-rays on
commercial-grade borosilicate, fused quartz, polymethylmethacrylate, and
polycarbonate samples up to doses of 100 kGy, to qualify their use as optical
materials in rad-hard LED-based luminaires. In addition, a Si bridge rectifier
and a SiC Junction Barrier Schottky diode for use in power supplies of rad-hard
LED lighting systems are tested using 24 GeV/c protons. The physical
degradation mechanisms are discussed for each element.
