An intelligent protection system for luminaires intended for outdoor use. The heating system protects electronic and mechanical components from temperatures below -10° C (14° F). This allows IP65+ luminaires to be used outdoors at temperatures reaching -20° C (-4° F). Moving-head fixtures intended for outdoor use are equipped with a standard sensor that allows measurement of the temperature in real time and adjustment of the internal temperature. This system considerably optimizes the service life of the mechanical and electronic parts.
