Abstract

Referred to here is a device for measuring the quantity of light in nurseries, which determines the quantity of light, the maximum illumination intensity, which is used to measure the quantity of light, being adjustable.

Description

Die Zusatzerfindung bezieht sich auf die Licht­ mengenmessung.The additional invention relates to the light quantity measurement.

Bei der Lichtmengenmessung werden Beleuchtungs­ stärken, die oberhalb der Beleuchtungsstärken liegen, die die Pflanze ausnützt, zur Messung der Lichtmenge in Kluxh nicht herangezogen.When measuring the amount of light, lighting is used strengthen that above the illuminance that the plant uses to measure the Amount of light not used in Kluxh.

Claims (1)

Das Lichtmengenmeßgerät ist in seiner Erweiterung dadurch gekennzeichnet, daß der Anspruch 1 der Haupterfindung ergänzt wird mit dem Text, daß die Lichtmenge ermittelt wird, die die Pflanze tatsächlich nutzt, indem ein oder mehrere Licht­ fühler zwischen den Pflanzen die Lichthelligkeit ermitteln.The extension of the light quantity meter is characterized in that claim 1 of the main invention is supplemented with the text that the quantity of light that the plant actually uses is determined by one or more light sensors between the plants determining the light brightness.
