DENTAL LED OPERATING LIGHT POLARIS
FUNCTIONS
POLARIS is based on the high performance LED
(Light Emitting Diode) technology. POLARIS, through
the use of a 10 low power LEDs system (1W each)
and the opportune combination of the illumination
flows, produces an high and adjustable light intensity
(from about 8.000 to 35.000 Lux).
The 10 LEDs system assures a light without shad-
ows. In fact, the 10 LEDs reflect light on independent
parabolas with 10 prisms each. This allows to obtain
100 individual light fields in different concentric posi-
tions and to realize a light pattern without shadows.
With this system, light remains without shadows also
in case of a single LED fault or multiple LEDs fault,
and this fact gives to the dentist the opportunity to
end the work.
The innovative LED technology allows to have a light
source with a lifetime of at least 50.000 h instead of
5.000 h of the halogen light.
LEDs have an onset time of nanoseconds and
an instant light emission instead of halogen lights.
Moreover POLARIS, don't use a cooling fan and it
eliminates, consequently, its noise.
POLARIS beams cold light. Cold light avoids the in-
crease of the temperature on the treatment area and
the unpleasant heating feeling by the patient.
Cold light is in fact a light without infrareds (IRs). IRs
can realize the dehydration phenomenon of tissues
during the surgery.
Moreover POLARIS doesn't generate UV rays. UV
rays can be dangerous for biological tissues, espe-
cially for nucleic acids and proteins which are the
most important absorbents of this kind of radiation.
POLARIS integrates a system, patented by
G.COMM, to regulate the colour temperature from
about 4200K to 6000K. Recent studies demonstrate
that dentist concentration increases through the rise
of colour temperature with the consequent reduction
of dentist eyestrain.
POLARIS allows to obtain a faithful colours' repro-
duction of lighted zone. Colour rendering index (CRI)
represents a measure of a light source's ability to
show object colours "realistically" or "naturally" com-
pared to a familiar reference source. With its high
CRI (>85), POLARIS assures a correct vision and a
huge chromatic reliability.
POLARIS makes more comfortable dentist's work,
especially in case of long surgeries. The region near
the dentist head tends to heat, but the use of cold
light reduces considerably the heating raise.
POLARIS has lowered consumption (less than 20W)
and an elevate reliability (LEDs have long lifetime
and system don't need cooling fan) in respect to
halogen light system.
