摘要:
A lighting apparatus (10), for example for applications in the show-business or entertainment sector, comprises:
a light-radiation generator (12), for example a laser generator, configured for projecting a lighting beam (LB) towards a lighting space in a certain direction (X12);
control circuitry (100) of the light-radiation generator (12) configured for controlling emission of the lighting beam (LB) by the light-radiation generator; and
processing circuitry (102, 104, 108) configured for calculating a thermal retinal radiance ratio (I, II, III, IV, V) of the light-radiation generator (12) as a function of a distance from the light-radiation generator (12) in the aforesaid direction (X12) and for acting on the control circuitry (100) of the light-radiation generator (12) in order to control the lighting beam (LB) of the light-radiation generator (12) as a function of the thermal retinal radiance ratio (I, II, III, IV, V), with the aim of maintaining the aforesaid thermal retinal radiance ratio below unity starting from a certain value of distance from the light-radiation generator (12) in the aforesaid direction (X12).
