Wind induced vibrations: A proposal of test profile for outdoor luminaires

Outdoor use luminaires are subjected to mechanical vibrations, mainly due to wind, that can generate stress conditions on the devices and affect their reliability performance. Starting from the study of international standards concerning vibration tests for luminaires, and from scientific literature, several laboratory tests have been performed to verify the behaviour of equipment subjected to wind induced vibrations. After that, a new test profile applicable to luminaires for outdoor use has been proposed in order to establish properly wind induced vibration levels and optimize luminaires testing costs.
