Abstract
Description
Die Erfindung bezieht sich auf ein Lichtsteueranlagen-System gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a light control system according to the preamble of claim 1.
Zur Steuerung von Licht im Raum sind Lichtsteueranlagen mit einem Dimmer allgemein bekannt, die über einen Lichtsensor im Raum die Helligkeit einer Raumbeleuchtung konstant halten. Hierbei erfasst der Lichtsensor das aus Tageslicht-Anteil und Kunstlicht-Anteil zusammengesetzte Mischlicht. Mit Hilfe des Dimmers erfolgt eine Nachregelung auf einen voreingestellten Helligkeits-Sollwert, d. h. der Helligkeits-Istwert wird laufend dem Helligkeits-Sollwert angepasst. Im Laufe der Zeit reduziert sich die Lichtausbeute einer Lichtquelle infolge Alterung, wodurch der im Neuzustand vorliegende maximale Helligkeitswert nicht mehr erreicht werden kann. Folglich kann der bei Projektierung der Lichtanlage vorgegebene Helligkeitswert nicht mehr erreicht werden.to Control of light in the room are light control systems with a dimmer commonly known about a light sensor in the room the brightness of a room lighting constant hold. In this case, the light sensor detects the amount of daylight and artificial light share composite mixed light. With the help of Dimmers, there is a readjustment to a preset brightness value, d. H. the brightness actual value is constantly going to the brightness setpoint customized. Over time, the light output of a reduced Light source as a result of aging, whereby the present in new condition maximum brightness value can no longer be achieved. Consequently, can the brightness value specified when configuring the lighting system can not be reached anymore.
Der Erfindung liegt die Aufgabe zugrunde, ein Lichtsteueranlagen-System anzugeben, mit welchem über die gesamte Lebensdauer der Lichtquelle eine gewünschte Helligkeit im Raum erzielt werden kann.Of the Invention is based on the object, a light control system specify with which over the entire life of the light source achieves a desired brightness in the room can be.
Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffes erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.These The object is achieved in conjunction with the features of the preamble according to the invention solved specified in the characterizing part of claim 1 features.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere dann, dass selbst am Lebensdauer-Ende der Lichtquelle noch die bei Inbetriebnahme – d. h. im Neuzustand der Lichtquelle – gewünschte Helligkeit im Raum problemlos erzielt wird. Im Vergleich zu herkömmlichen Lichtanlagen muss zwar eine Lichtquelle höherer Lichtleistung installiert werden, jedoch weist diese Lichtquelle aufgrund der Überdimensionierung eine wesentlich höhere Lebensdauer auf, da sie während einer großen Zeitspanne der Lebensdauer lediglich mit reduzierter Spannung zu beaufschlagen ist.The particular advantages can be achieved with the invention that even at the end of the life of the light source still at startup - d. H. when new the light source - desired brightness is easily achieved in the room. Compared to conventional Although lighting systems require a light source with higher light output, however, due to oversizing, this light source is essential higher Lifespan up as they are during a big one Time span of life only with reduced voltage too is charged.
Weitere Vorteile sind aus der nachstehenden Beschreibung ersichtlich.Further Advantages will be apparent from the following description.
