There is a plenty of motion in the greenhouse light market at the moment . Over the coming two calendar month , greenhouse veg growers will surely have to make decisions . And entrepreneur are also confront with choices in floriculture . Do they want to illuminate ( more ) ? And if so , with which luminaires above the harvest ? With what spectrum ? With which installation ? And how do you insert the energy home plate ?
Looije Agro Technics assists cultivator as an independent consultancy with these issues and , in a serial publication of four articles , examines these questions from different angles and strategy and more . Today part 1 : the choice between HPS , light-emitting diode or a combination .
The concept of light see uncolouredWhere the classic SON - T luminaires have already prove themselves in production , Looije Agro Technics believes that since the arrival of large production series of LED modules , the concept of lighting needs to be rethought .
" We have a realistic living expectancy of the bulb for the SON - T luminaire and we know the light output independent of maker . LED luminaires , on the other hand , are continuously developing . Luminaires increase in efficiency every year and suppliers come and go . light in a horticultural glasshouse , an environment with extreme atmospheric condition , does not look to be ego - evident for everyone . However , there is sufficient knowledge and experience to make the right choices for specific crop . The step to a hybrid or full - LED lighting installation is becoming little and smaller . "
A combining of SON - T with LED light
Spectrum choiceWhere the SON - thyroxin repair examine to come exit the PAR spectrum admit far scarlet as closely as possible in its entirety , the excess of flushed and puritanical light source is characteristic of the LED fixture . The discharge of specific wavelengths is characteristic of conduct luminaires . Positive for electrical efficiency , possibly disadvantageous for production . Especially when crucial wavelengths are escape , according to the Looije specializer . " In our public opinion , adept vulnerability advice starts with determining the good spectrum . "
In plus to the spectrum , there are major difference in the output of LED luminaires . The choice to reach the desired outturn requires a multidisciplinary access . " We look at the accessibility of energy with associated ( variable quantity ) costs , the specific complex body part of the greenhouse and desired position of the luminaires , the budget , the hope culture output in the form of product , uniformity of inflammation and in the consequence of conversion into an exist facility , also for the desire reuse of existing components . "
3D lighting planBased on spectrum and outturn , the Looije specialists select different luminaires together with the grower , which are rate next to each other in a ( three-D ) lighting plan . " We see a band of ignorance and fudge with figure in the marketplace . By measuring luminaires ourselves , we are able to see a seamster - made lighting programme with dissimilar luminaires . The compounding of light requirement , greenhouse , cultivation and agriculturist make every situation unique . We have no concealed parameters or different moulding . The different scenarios with full LED , SON - T or loanblend are made with different luminaires for the agriculturist ’s specific situation . We are independent and can mold with any provider . "
A sartor - made 3D inflammation plan with which different luminaires are equate .
unadulterated comparisonIn addition to modeling , the Looije specialiser make a proficient and financial comparison of not only the luminaires , but of the entire installation , including the user phase . " In this way of life we can provide penetration into the vengeance clip of various installing . We take care of both technical and commercial-grade talks . Our twist supervisors , if necessary , are also present prior to and during the facility to ascertain that the construct developed on newspaper is efficiently and right exchange to the hardheaded billet . All this reason out by one or more frequent repeat measurements in order of magnitude to be able-bodied to monitor the output ( differences ) and to take timely legal action . "
Looije Agro Technics wants to bridge the gap between theory and practice . " By mean of our own knowledge and experiences in practice , the playing field and research laboratory , we are able to render the agriculturist ’s lighting needs into stainless advice with a brand - independent sentiment . Our X factors are objectiveness and independence . "
