Description
Anwendungsgebietfield of use
Die Erfindung betrifft eine Vorrichtung zur Beeinflussung von Pflanzenwachstum durch definiertes Einstellen eines Lichtspektrums.The invention relates to a device for influencing plant growth by defined setting of a light spectrum.
Charakteristik bekannter technischer LösungenCharacteristic of known technical solutions
Die künstliche Beleuchtung von Pflanzen in Klimaschränken für Laborzwecke sowie in Gewächshäusern wird allgemein angewandt.The artificial lighting of plants in climatic cabinets for laboratory use and in greenhouses is widely used.
Dabei kommen zum Beispiel Glühlampen zum Einsatz. Diese geben zwar das Spektrum des Sonnenlichts gut wieder, sind aber in der Energieausbeute schlecht.In this case, for example, incandescent lamps are used. Although these reflect the spectrum of sunlight well, but are poor in energy yield.
Besser geeignet sind Leuchtstofflampen, die zwar das Sonnenlicht schlechter imitieren aber im Wirkungsgrad besser sind.Fluorescent lamps are more suitable, although they imitate sunlight less well but are better in terms of efficiency.
Noch besser im Wirkungsgrad sind Natriumhochdrucklampen.Even better in efficiency are sodium high-pressure lamps.
Besonders LED-Leuchten sind zurzeit im Wirkungsgrad am effektivsten.Especially LED lights are currently the most effective in terms of efficiency.
Dabei werden weiß strahlende LED's oder farbige LED's oder eine Mischung aus beiden eingesetzt.It uses white LEDs or colored LEDs or a mixture of both.
Bei allen aufgeführten Leuchten ist es nur möglich die Leuchte ein- oder auszuschalten oder bei einigen Leuchten auch zu dimmen.For all listed lights, it is only possible to turn the light on or off or dimming in some lights.
Eine Änderung des Spektrums des Lichts ist nicht möglich.A change of the spectrum of the light is not possible.
Pflanzen wachsen in Wachstumsphasen und können in diesen Phasen durch Licht mit unterschiedlich definiertem Spektrum beeinflusst werden. Das ist mit den bekannten Lampen nicht möglich.Plants grow in phases of growth and can be influenced in these phases by light with differently defined spectrum. This is not possible with the known lamps.
Ziel der ErfindungObject of the invention
Ziel der Erfindung ist es, mittel einer Vorrichtung im Spektrum veränderbares Licht zu erzeugen, sodass die Pflanze in ihren einzelnen Wachstumsphasen optimal gedeiht.The aim of the invention is to produce by means of a device in the spectrum changeable light, so that the plant optimally thrives in their individual growth phases.
Wesen der ErfindungEssence of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, bei der einzelne Spektralanteile von Licht separat in der Lichtstärke einstellbar sind.The invention has for its object to provide a device in which individual spectral components of light can be adjusted separately in the light intensity.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass in einer Vorrichtung eine Leuchte mehrere LED-Gruppen mit jeweils unterschiedlicher Emissionswellenlänge eingebaut ist und dass diese einzelnen Gruppen separat in der Intensität regelbar sind.According to the invention the object is achieved in that in a device, a light multiple LED groups, each with a different emission wavelength is installed and that these individual groups are separately controlled in intensity.
Man kann dabei zwei Gruppen LED mit einer ersten roten Lichtfarbe und einer zweiten blauen Lichtfarbe verwenden, oder drei Gruppen LED mit einer ersten roten Lichtfarbe und einer zweiten blauen Lichtfarbe und einer dazwischen liegende Lichtfarbe.It is possible to use two groups of LEDs with a first red light color and a second blue light color, or three groups of LEDs with a first red light color and a second blue light color and an intermediate light color.
Auch ist es möglich, dass eine erste Gruppe LED nicht geregelt wird, sondern im Einzustand immer 100% Leistung erzeugt und die anderen Gruppen in der Leistung geregelt werden und somit das spektrale Verhältnis eingestellt wird. Die Regelung der Leistung kann mittels Gleichstrom oder Pulsmodutationsverfahren erfolgen.It is also possible that a first group LED is not regulated, but always produces 100% power in the on state and the other groups are regulated in the power and thus the spectral ratio is set. The regulation of the power can be done by means of direct current or pulse modulation method.
Die Zeitsteuerung erfolgt sowohl über einen gesamten Tag als auch über die gesamte Wachstumsperiode im festgelegten Ablauf. Dadurch kann man getrennt ein optimales Keimwachstum, ein optimales Streckungswachstum und eine optimale Reifephase erreichen.The time control takes place both over an entire day and over the entire growth period in the specified sequence. This allows you to separately achieve optimal seed growth, optimal growth extension and an optimal maturation phase.
Es ist möglich die Regelung so einzustellen, dass ein optimaler Pflanzenschutz erfolgt, wenn die Schädlinge auf die Lichtabläufe reagieren.It is possible to adjust the control so that optimal plant protection takes place when the pests react to the light processes.
