De Sisti Giotto

 
FEATURES

• Compact, construction and modular design for cyclorama over-head illumination, using linear tungsten quartz-halogen filament lamps having R7s sockets and length of 118mm.
• Rugged and Lightweight Carbon Steel housing with low glare black epoxy powder coating, with front curved supports for filter frame, in order to hold the colored filters almost perpendicular to the output light rays and guarantee best output energy transmission and no color aberration.
• Compact overall housing height to minimize geometrical influence on back-lighting fixtures assembled between the background and the top cyclorama lights (other brands of top cyclorama lights use a tall housing that very often is obstructing the above mentioned back-lights).
• High efficiency convection cooling.
• High Efficiency and innovative optical system for homogeneous illumination of tall backgrounds. The reflector of the Giotto is formed by three different sectors:
  • SECTOR B: this portion of reflector is formed by a diffused material and is contributing for lighting the upper/medium region of the cyclorama height and has a special shape to avoid the lamp filament image projection on the background.
  • SECTOR A: this section is reflecting and conveying a big amount of light to the bottom part of the cyclorama, in order to compensate the longer distance of such part from the fixture and to obtain the even illumination of the background. This sector is built using a special semi-diffused aluminum.
  • SECTOR C: this portion of reflector is shaped as a spherical sector and it is built with high reflectivity aluminium. The light rays emitted by the lamp are reflected by the SECTOR C back to SECTOR A and therefore used to lit the bottom of the cyclorama
