Plasma-i AS1300 Light Engine
The Plasma-i Light Engine generates
a solar like light flux. The lamp power can be
set by software to a desired level between 500W
and 1300W and the light spectrum remains almost
unchanged between 600W and 1300W power setting.
This unique spectral property
is achieved with our electrodeless bulb design,
where the bulb converts the externally generated
HF energy into light at high efficiency.
The HF energy (microwaves) are
generated with a magnetron that is powered from
an adjustable stabilized power source.
Both the light engine &
power supply are air cooled with fans. |

Characteristical
variances in bulb mix range: The CRI is
between 98 (60 lm/W) & 80 (140 lm/W)
and hot re-strike is between 20 & 180
seconds depending on which bulb mix is used.
Operating Conditions:
Ambient temperature +5°C to +35°C
Humidity <60%, non-condensing. As no
filter is provided on the air cooling system
the standard system has to operate in a
clean environment with no dust emitting
processes nearby.

Popular
light sources currently used for solar simulation
include the Hydrargyrum Quartz Iodide (HQI)
lamp which is a type of high-intensity discharge
(HID) light, produces its light by an electrical
arc in a gas envelope using electrodes.
Note that Hydrargyrum is the Latin name
for the element mercury. Also Xenon
lamps that use tungsten metal electrodes
in a glass tube filled with xenon gas. For
xenon flash tubes, a third "trigger"
electrode usually surrounds the exterior
of the arc tube. Xenon lamps often have
a relatively short lifetime of 200 to 2000
hours. As with all electrode based light
sources the colour quality and luminous
efficiency of the light changes dramatically
as the electrodes burn away during use.
And the tungsten lamp, which is similar
to the classic incandescent domestic version,
but with an extra high-temperature filament
so that it gives high illumination and high
colour temperature for the price of a short
lifetime. In nearly all cases solar simulators
using a combination of these old technologies
can only represent part of the solar spectrum
at the same time and many have extremely
elaborate and vulnerable reflector and filter
systems to simulate the Sun’s radiation
at all wavelengths.
With Plasma International
Lighting Systems there are none of these
risks or problems, the spectral output is
truly full and continuous, not just for
hours, but for years, with no qualitative
or quantitative degradation.
There are currently 2 variations
of the plasma lamp available, the Standard
Sulphur lamp (SS0) and the Triple A class
Solar Simulator lamp (AAA).

A solar
simulator is now measured as class A, B,
or C for Spectral Match, Non-Uniformity
of Irradiance, and Temporal Instability
of Irradiance. Solar simulators utilizing
plasma-i lamps are easily designed to meet
Class A performance for all 3 of the test
requirements. The three standards that define
solar simulator performance, in order of
most demanding parameters first:
- JIS C 8912-1998,
Solar Simulators for Crystalline Solar
Cells and Modules
- IEC 60904-9 Edition 2 (2007)
Photovoltaic Devices – Part 9:

A Simplified Perspective
from Clive Wing:
The SS0 lamp has hardly
any UV light and less red light than the
AAA lamp that the Dutch researchers have
named the Artificial Sun.
Spectral Match –
How close it is to the power of visible
and invisible colours that are in sunlight.
Non-Uniformity of irradiance - How evenly
spread out (distributed) it is.
Temporal Instability – How constant
the output is.
A New way of Measuring
is Needed
We can not claim higher
luminous efficiency than a sodium lamp or
higher PAR (Photo synthetically Active Radiation)
than a metal halide or sodium lamp because
when we measure our plasma lamp in lumens
or micro moles it nearly always measures
at least 30% less than other HID lamps of
the same wattage. We will claim a higher
PUR (Photo synthetically Useful Radiation)
value because we believe the plasma lamps
that we manufacture are the only lamps that
are truly a full and continuous spectrum
and thus, completely unlike LED's, deliver
all of the light that is useful for photosynthesis.
Conventional methods of
measuring light for humans use lumens, deemed
useless for horticulture, horticulturists
measure light in micro moles (µmoles).
Working with British, German and Dutch horticulturists
and researchers I have learnt that micro
mole measurements are the best indicator
we have at this time. The results from real
world tests indicate that a plasma lamp,
that measures 30% micro moles 'less' than
a High Power Sodium Lamp of same wattage,
produces at least 30% more biomass, and
can fully grow cucumbers to European standards
10 days sooner. After eating them myself
I can confidently write that in my opinion
cucumbers grown in continuous full spectrum
light with a low PAR value, compared to
HPS, have better aroma, flavour and colour.
My hunch is that the nutritional value will
be far higher also, especially as thinking
it will be the same is disregarding the
principles of logic! |
