FIELD: electrical engineering.
SUBSTANCE: 12-colour illuminator includes lamp 17 with hot cathode, mounting panel 14, diffuser 30 and supporting member 20. The mounting panel 14 contains lamp 17 with hot cathode and has hole 14b for light passage from lamp 17 with hot cathode. Diffuser 30 is placed before the lamp 17 with hot cathode and closes hole 14b. Supporting member 20 supports diffuser 30 at the side close to lamp 17 with hot cathode. Mounting panel 14 includes the area facing diffuser 30 and is set in LA area of light source with installed lamp 17 with hot cathode and empty LN area without lamp 17 with hot cathode. Diffuser 30 has a higher coefficient of luminous reflectivity at DA area covering light source in comparison with DN area covering the empty area. Diffuser 30 has maximum luminous reflectivity Rmax and minimum luminous reflectivity Rmin, and supportive element 20 is envisaged at the area covering the area of diffuser 30 that has luminous reflectivity R that meets the following equation (1).
EFFECT: prevention of irregular brightness.
