Abstract

The device provides a warning signal when the room lights are switched on and the ambient light level is sufficient to render them unnecessary, to allow saving in electrical energy to be made. It comprises a battery-operated device, controlled by a microcontroller, with intensity modulation of the artificial lighting to discriminate it from the ambient light. Pref. the artificial light is intensity modulated at twice the supply network frequency, with the warning signal supplied in dependence on the ratio between the detected artificial light level and the ambient light level.

Description

Die Erfindung betrifft eine Vorrichtung zur Detektion unnötig eingeschalteter Raumbeleuchtungen. Eine derartige Vorrichtung ist aus der DD 2 65 505 A1 bekannt.The invention relates to a device for detecting unnecessarily switched on Room lighting. Such a device is known from DD 2 65 505 A1.

In vielen Büroräumen wird bei Tagesanbruch die Deckenbeleuchtung eingeschaltet, wenn das Tageslicht noch nicht ausreichend intensiv scheint. Mit stärker werdendem Tageslicht wird oft vergessen, die Beleuchtung wieder auszuschalten. Das führt zu einem vermeidbaren Energieverbrauch. Bekannt sind Geräte, die das Licht in Abhängigkeit von dem Umgebungslicht automatisch ein- und ausschalten. Gemäß der DD 2 65 505 A1 wird eine Beleuchtungsschalteinrichtung beschrieben, die zur Vermeidung von Rückkopplungen der geschalteten Leuchtquelle auf den Sensor der Schalteinrichtung die Modulation der künstlichen Lichtquelle mit der doppelten Netzfrequenz ausnutzt. Es handelt sich dabei jedoch um eine stationäre, in vorhandene Stromkreise einzubauende Einrichtung.In many offices, the ceiling lighting is switched on at dawn, if that Daylight still does not seem sufficiently intense. With increasing daylight often forgot to turn the lights off again. That leads to an avoidable Power consumption. Devices are known which switch the light depending on the Automatically switch ambient light on and off. According to DD 2 65 505 A1 describes a lighting switching device which is used to avoid Feedback of the switched light source on the sensor of the switching device Modulation of the artificial light source with twice the mains frequency is used. It deals However, it is a stationary device to be installed in existing circuits.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine technisch einfache, ohne Installationsaufwand von jedermann zu gebrauchende Einrichtung zur Energieeinsparung bereitzustellen.In contrast, the invention has for its object a technically simple, without Installation effort to be used by everyone to save energy to provide.

Diese Aufgabe wird durch die im Patentanspruch angegebenen Merkmale gelöst.This object is achieved by the features specified in the patent claim.

Anhand der Fig. 1-3 wird die Erfindung näher erläutert.Referring to Figs. 1-3, the invention is explained in detail.

Mit einem lichtempfindlichen Element wird dabei die Lichtstärke an dem Standort des Gerätes gemessen und eine Aufteilung der gemessenen Lichtstärke in die Anteile natürlichen und künstlichen (Raumbeleuchtung) Lichts vorgenommen (Fig. 1). Das Verfahren beruht darauf, das Licht in den natürlichen, zeitlich nicht in der Intensität modulierten, und den künstlichen, zeitlich mit der doppelten Netzfrequenz modulierten Anteil zu zerlegen. Der sinnvolle Einsatz des Verfahrens ist daher an Räume gebunden, deren Beleuchtung mit Leuchtstoffröhren erfolgt, da die Modulation des Lichtes bei diesen Lampen zuverlässig detektiert und quantifiziert werden kann.The light intensity at the location of the device is measured with a light-sensitive element and the measured light intensity is divided into the proportions of natural and artificial (room lighting) light ( FIG. 1). The method is based on dividing the light into the natural portion, which is not time-modulated in intensity, and the artificial portion, which is temporally modulated at twice the network frequency. The sensible use of the method is therefore tied to rooms that are illuminated with fluorescent tubes, since the modulation of the light in these lamps can be reliably detected and quantified.

Die Betrachtung des Verhältnisses dieser Anteile ermöglicht die Entscheidung, ob die Beleuchtung notwendigerweise oder überflüssigerweise eingeschaltet ist. Die Beleuchtung wird danach als nicht notwendig erachtet, wenn der Anteil des natürlichen Lichtes den Anteil des künstlichen Lichtes beträchtlich überwiegt. Damit die Untersuchung auf einer Arbeitsfläche im Raum vorgenommen werden kann, wurde ein netzunabhängiges Gerät entwickelt, das einen Warmton aussendet, wenn die Beleuchtung unnötig eingeschaltet ist.Looking at the ratio of these shares allows you to decide whether the Lighting is switched on necessarily or unnecessarily. The lighting is then considered unnecessary if the proportion of natural light is the proportion of artificial light predominates considerably. So that the investigation on a Work surface can be made in the room, became a network-independent device developed that emits a warm tone when the lighting is switched on unnecessarily.

Der Vorteil des beschriebenen Verfahrens zur Erkennung überflüssig eingeschalteter Beleuchtungen liegt auch darin, daß kein Abgleich auf eine bestimmte Lichtstärke vorgenommen werden muß.The advantage of the described method for the detection of unnecessarily switched on Illumination is also due to the fact that there is no adjustment to a certain light intensity must be made.

Der mit der Erfindung erreichte Vorteil für den Anwender ergibt sich aus der Stromeinsparung, die insbesondere zu den Hauptlastzeiten, nämlich in den Stunden um die Mittagszeit, zu erzielen ist. Bei einer Leistungsaufnahme einer Zimmerbeleuchtung mit acht Leuchtstoffröhren von 8×36 W=286 W elektrischer Leistung und einem durchschnittlichen täglichen Einspareffekt von 2 Stunden, ergibt sich bei 200 Arbeitstagen eine Einsparung von ca. 115 kWh pro Jahr. Dies führt zu einer schnellen Amortisierung des Gerätes, da der einfache Aufbau einen niedrigen Stückpreis zuläßt. The advantage achieved for the user with the invention results from the Electricity savings, especially during peak periods, namely in the hours around the Lunchtime, can be achieved. With a power consumption of a room lighting with eight Fluorescent tubes of 8 × 36 W = 286 W electrical power and an average daily saving effect of 2 hours, there is a saving of 200 working days approx. 115 kWh per year. This leads to a quick amortization of the device, since the simple construction allows a low unit price.  

Weitere Ausgestaltung der Erfindung:
Eine vorteilhafte Ausgestaltung der Erfindung wird im folgenden angegeben: Die praktische Ausführung des Gerätes besteht aus nur einem lichtempfindlichen elektronischen Sensor (IC1), mit dem in schneller Folge die Lichtstärke gemessen wird und aus einem Mikrokontroller (IC2) mit dem die weitere Auswertung vorgenommen wird (Fig. 2). Aus den - über einige Netzperioden - gemessenen Minima- und Maximawerten der Lichtintensität können der natürliche und der künstliche Lichtanteil sicher bestimmt werden. Der Mikrokontroller führt diese Messungen und Berechnungen in regelmäßigen Abständen von ca. 30 Sekunden durch und entscheidet anhand eines voreinstellbaren (programmierten) Verhältnisses zwischen künstlichem und natürlichem Licht, ob ein Warnsignal gegeben werden soll. Das von dem Mikrokontroller generierte Warnsignal wird von einem Piezo- Schallwandler abgestrahlt. Das Meßprinzip ließe auch eine Auswertung in analoger Schaltungstechnik zu, der Vorteil der realisierten Mikrokontrollertechnik liegt jedoch in dem geringen Stromverbrauch, so daß ein Gerät (Fig. 3) ca. 2-3 Jahre ohne Batteriewechsel betrieben werden kann.
Another embodiment of the invention:
An advantageous embodiment of the invention is given below: The practical design of the device consists of only one light-sensitive electronic sensor (IC1), with which the light intensity is measured in rapid succession, and of a microcontroller (IC2) with which the further evaluation is carried out ( Fig. 2). From the minimum and maximum values of light intensity measured over a few network periods, the natural and the artificial light component can be reliably determined. The microcontroller carries out these measurements and calculations at regular intervals of approx. 30 seconds and uses a presettable (programmed) ratio between artificial and natural light to decide whether a warning signal should be given. The warning signal generated by the microcontroller is emitted by a piezo sound transducer. The measuring principle would also allow an evaluation in analog circuit technology, but the advantage of the realized microcontroller technology lies in the low power consumption, so that a device ( Fig. 3) can be operated for about 2-3 years without changing the battery.
