International Patent N° WO 2013/024501 A1
Advanced Optics for LED Projector with FRESNEL or PLANAR-CONVEX Lens
OVERVIEW
The Super LED F4.7 is a high efficiency Fresnel lens spotlight using the innovative High Power 60W COB (Chip
on Board) LED ARRAY, in combination with the DE SISTI Internationally Patented optical system for LED FRESNEL
and with an enhanced CRI (Color Rendering Index) higher than 90 for appropriate chromacity performances.
The Lighting Fixture is DMX Controlled from 0 to 100% with a super smooth Dimming and a negligible variation
of Colour Temperature while controlling the Light intensity.
The LED MAGIS is available with either Tungsten (3.200°K) or Daylight (5.600°K) Balanced CCT (Correlated
Color Temperature), in both cases with a CRI higher than 90 and both in Manual or Pole operated versions.
The lighting Performances of the Tungsten Balanced CCT from medium to full flood are similar to those of a
750W tungsten Fresnels, while the Daylight Balanced CCT is similar to a 250W HMI.
The fixture combines the classical SPOT/FLOOD beam control on an equivalent FOCUS RANGE to a
conventional lamp fresnel, with an excellent barn door cutting.
It utilizes Standard accessories from the DE SISTI range of equivalent Fresnel Lens size, such as Barndoor, Colour
Frame, Cones, scrims.
FEATURES
 120 mm. (4.75”) diameter high quality, shock resistant Borosilicate glass Fresnel lens on spring supports.
 Rugged and Lightweight Carbon Steel housing with low glare black epoxy powder coating, with internal
double walls and reinforces.
 High efficiency Self Stabilizing Active Cooling: Automatic, thermal stabilization of the LED operating
temperature is managed by an internal thermal sensor and CPU, variable speed fan and heat sink to
maintain the LED Array’s constant temperature at a maximum of 65°C. The hydro dynamic bearing fan
operates silently with a very low RPM.
 Special Patented Optics for LED Technology.
 Helix Screw driven focus mechanism which guides Teflon bushings supported LED ENGINE along 2 rods. This
ensures smooth operation during focusing, in any tilting position of the fixture. The Teflon bushings also
provide a wiping action, which cleans the steel guide rails during focus
 The unit is equipped with a hinged lens door with wire-guard, it includes accessory holding brackets. One of
the 4 brackets has a locking knob and is spring loaded, it can be locked to either safely hold barndoor, color
frame and scrims or to be rotated 90° and locked in an open position for fast accessories changes.
 The accessories are secure regardless of the orientation of the fixture. Accessories have been designed for
one hand installation.
 Available with either positive lock manual yokes for comfort and ease of handling, or pole operated yokes
which can be used via the lighting pole for Panning and Tilting the lights as well as manually, since the
mechanical activators are equipped with clutches.
