    摘要： A lighting module (30) comprises a first terminal (30a) and a second terminal (30b) configured to receive a supply voltage ( V out ), and a string of light sources (LED 1 , LED 2 , ..., LED i , ..., LED n-1 , LED n ) connected in series between said terminals (30a, 30b).
    The lighting module (30) comprises a first protection circuit (40a) and a second protection circuit (40b), which are connected in series to the string of light sources. The first protection circuit (40a) is connected between the first terminal (30a) and a first light source (LED 1 ) of the string, and the second protection circuit (40b) is connected between a last light source (LED n ) of the string and the second terminal (30b) .
    The protection circuits (40a, 40b) comprise respective junctions or respective MOS field effect transistors, the value of impedance of which depends on the value of the supply voltage ( V out ).

    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).

    摘要： A light fixture is provided with a light source assembly (10) configured to generate visible light radiation of different colours; an optical device (19) configured to process at least a portion of the light radiation emitted by the light sources (18) so as to form a light beam extending substantially along an optical axis (O); at least one beam processing element (21) located downstream of the optical device (19) and configured to selectively intercept the light beam; the beam processing element (21) comprising at least one portion (24; 25) movable between several positions; a control device (13) configured to control the light source assembly (10) either on the basis of the position of the movable portion (24; 25) of the beam processing element (21) or on the basis of a parameter correlated to the position of the movable portion (24; 25) of the beam processing element (21).
