to the grower on any device, anytime, anywhere. There
are four Hortisensemodules - asset performance, light
management,maintenance and crop yieldmanagement.
Claimedbenefits include increased efficiency of the grow
light installation and increased yieldper sq.m., without
requiring separate systems.We are informed thatmore
than200ha have already been connected toHortisense in
countries includingRussia, Poland, Norway, France and
theNetherlands.
DHLight showed a new LED luminaire formulti-layer and
vertical farming systems, which can alsobe used as a top
light. Called the LED-LE, therewas a very good reason
why the lights at IPMweredimmedby 90%. At full power
the 2m lamp at the show emits over 2,000mmols and
would require visitors to haveworn sunglasses!
Available in a range of different circuit boards, lengths
and cooling systems, smaller lengths of 40cm, 80cm and
1.2m (up to 200watts) are air-cooledwhile longer lengths
from 1.2-2m arewater-cooled. However, this depends
on the circuit board selected and it is alsopossible to
order water-cooled1.2m versions. The lamps canbe
installedonboth sides of the fitment, which is useful when
interlighting.
With40 years of street lightmaking experience, 12
years agoGerman companyBLV, branched into the
horticultural lightingworld, supplyingGavitawithHPS
lamps. Operating fromproduction sites nearMunich and
inPoland, last year the company decided togo it alone.
The first signof thiswas at GreenTech2016 in
AmsterdamwhereBLV showed a range of Horturion
HPSTL lamps (600/750/1000w) andMH (250-1000w)
lamps, plus a couple of new LED concepts. Today, with
the exceptionof top and interlighting LEDs (both in
development), the company reckons to have a range and
recently installed its first bigproject.
The newGreenPower LED toplightingmodules on
Philips Lighting’s standhelps growers improve the growth
of lettuce, herbs and high-wire vegetable crops. The
company says both versions offer a higher light efficacy of
up to 3.3µmol/J, a longer lifetime of 35,000burning hours
(25,000 for the former toplightingmodule) and increased
energy efficiency compared to the formermodule.
The 520µmol/s photon flux version is designed to
enhance growthof high-wire tomato and cucumber
crops by producing the optimal amount of light in a full
LED system, while using less energy. The firm says the
620µmol/s version is ideal for increasing light output for
horizontal cultivationof lettuce and herbs. The 400v input
voltagemodulewill replace the current 400v toplighting
portfolio, andwill be availablebefore the summer for the
European, Asian andAustralianmarkets.
Philips Lighting also showed theGrowWise control
systemwhich allows growers and researchers to easily
create and run customLED light recipes tomeet the
needs of specific crops to improvequality, productivity
and efficiency. The control systemhas beendeveloped
toworkwith theGreenPower LEDproductionmodule
“Dynamic”. It canbe used as a standalone systemor
integrated into a climate or logistic computer system.
Described as the company’s first step towards digitisation
of Horti LED lighting systems, GrowWise controls four
LED colour spectra - deep red, blue, white, and far red as
well as the light duration and intensity. APhilips Lighting
light recipeprovides the settings for the light spectrum,
intensity, illuminationmoment, uniformity andpositioning,
and the new control system allows growers to create
their own time-based recipes to steer specificplant
characteristics, from compactness, colour intensity and
branchdevelopment to flowering andmore to improve
results.
Danish firmSenmatic showed its LED light controller,
and a system thatmakes it possible to control the light
intensity and red/blue ratioof the FL300 andFL100 for
thebest results. The company recommends installing
SANlight showed a newly-developedmodule that allows
different numbers of itsP-4Series luminaires tobe combined,
todevelop a system to replace 400, 600 and 1000watt
HPS lamps.
Added toValoya’s existing ranges L, C, B andR ranges, the
newBX-Series LEDs is described as an evolutionof the
existingB-Series.
