Abstract: A lighting apparatus for show-business or entertainment sector comprises a light-radiation generator for projecting a lighting beam towards a lighting space that includes one or more undesired lighting zones. A motorization causes the lighting beam to scan the lighting space as a function of scanning-control signals as received by the lighting apparatus. Driving circuitry is provided, configured to control emission of the lighting beam, as well as processing circuitry configured to sense the scanning-control signals received and the scanning position of the lighting beam of the light-radiation generator. As a result of the detection of received scanning-control signals that can lead the lighting beam to being brought into the undesired lighting zone, the processing circuitry acts on the motorization and/or on the driving circuitry of the light-radiation generator, containing projection of the lighting beam directed towards the undesired lighting zone and preventing possible risks of a photobiological nature.
