A lighting device comprising, one or more semiconductor light-sources for generating a light beam, at least a motor for rotating said light beam, and a controller for controlling speed of rotation of the motor and intensity of the light- source and monitoring the operating conditions, detecting failures of the lighting device and/or, any of its components and setting off alarms which could be audio/visual and/or, radio or, telecom equipment using land and/or, air and/or, satellite links. The light beam generated by the light-sources is rotated. The light assembly broadly finds application in aviation industry, obstacle beacons, lighthouses and entertainment industry. |
