Cyclorama DE SISTI DUCCIO  3 - 4233.120

The Duccio groundrow cyclorama luminaire is the result of an accurated design from De Sisti which has developed a floor standing source to produce artificial horizon or effects on a cyclorama and to be used in conjuction with the Giotto Top Light System for very tall depths or whenever it’s required. The unit is built in bunched and slotted sheet metal with an asymmetrical reflector conceived with a revolutionary shape and material to allow outstanding photometric characteristics. The Duccio compartments are conceived to be added together in order to have a configuration of two or more units. Each compartment is complete with stainless steel wire guard and colour frame, which is designed  to hold the gel almost perpendicular to all the emitted light beam in order to have no color aberration on the projection.

Thee Duccio is a compact, high quality & modular ground-row lighting fixture, with an exceptionally even output over the projected area, achieving a uniform distributed illumination of backgrounds.
Its modular construction allows various configuration by combining 2, 3 or 4 pieces of the basic compartment. Each compartment accepts linear quartz-halogen lamps with R7s caps 118 mm. overall length:
• 118 mm (Mod. N° xxxx.210) 120 V & 230-240V lamps available Max. Power 1.000W per lamp
The standard compartments are equipped with individual power cord of 1 m., but multi-pin versions are available on request for multiple compartments configurations.

• Compact, construction and modular design for cyclorama ground-row 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 with tilt adjustable foot, hinges on sides and bottom cam-locks to attach compartments together in either linear or corner arrangments
• High efficiency convection cooling
• High Efficiency and innovative optycal system for homogeneous illumination of backgrounds. The reflector of the Duccio is formed by three different sectors:
• SECTOR B: this portion of reflector is formed by a diffused material and is contributing for lighting the lower/medium region of the cyclorama heigth and has a special shape to avoid the lamp filament immage projection on the background.
• SECTOR A: this section is reflecting and conveying a big amount of light to the top 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 a high reflectivity aluminum. The light rays emitted by the lamp are reflected by the SECTOR C back to SECTOR A and therefore used to lit the top of the cyclorama
• Such a unique optycal system is guaranteeing not only the asymmetrical emission required, but an higher efficiency of the DUCCIO if compared with other competitive products. Also the special shape of the optycal system is permitting the savings on the overall heigth of the lighting fixture
•  
• Flexible filter frame per compartment, to keep the gel tangential to the light output rays so as to achieve the best coefficient of transmission of the color filters, avoiding their overheating and eliminating color aberration on the projection
