Description

Verlustleistungsarmer Stromspardimmer für gleichstromgespeiste Glühlampen.Power saving dimmers with low power loss for DC powered ones Lightbulbs.

Die Erfindung betrifft einen elektronischen Dimmer für Glühlampen, die mit Gleichstrom aus Batterien betrieben werden, insbesondere bei Fahrzeugen, bei denen die Batterien nicht ständig nachgeladen werden (Yachten, Campingwagen), oder bei Handleuchten, bei denen Glühfadenlampen aus Batterien begrenzter Kapazität betrieben werden (Taschenlampen).The invention relates to an electronic dimmer for incandescent lamps, which are operated with direct current from batteries, especially in vehicles in which the batteries are not constantly recharged (yachts, caravans), or hand lamps where filament lamps are operated from batteries of limited capacity be (flashlights).

Die Helligkeit einer gleichstrombetriebenen Glühlampe soll so einstellbar sein, daß einerseits für die Beleuchtung die volle Helligkeit erreicht wird, andererseits das Licht gedämpft werden kann, um bei Nacht nicht zu blenden. Dies ist nützlich bei Yachten, um den Ausguck nicht durch die Raumbeleuchtung oder Kartentischbeleuchtung zu blenden. Eine andere Verwendung ist bei Campingwagen als Nachtlicht gegeben, oder bei Taschenlampen für die Helligkeitssteuerung .The brightness of a DC-operated incandescent lamp should be adjustable so that on the one hand the full Brightness is achieved, on the other hand the light can be dimmed so as not to dazzle at night. This is useful for yachts so as not to dazzle the lookout with the room lighting or the map table lighting. Another use is in camper vans given as night light, or with flashlights for brightness control.

Es ist bekannt, Dimmer in der Wechselstromtechnik für das Dämpfen der Lampenhelligkeit einzusetzen. Dabei werden Schaltelemente (z.B. Thyristoren) eingesetzt, die beim Nulldurchgang der Wechselspannung von selbst verlöschen und durch eine Triggerung aus einem Steuerkreis in Phasenanschnitt- oder Halbwellenansteuerung wieder zünden.It is known to use dimmers in alternating current technology for damping lamp brightness. There are switching elements (e.g. thyristors) are used, which extinguish themselves when the AC voltage crosses zero and are triggered by a Re-ignite control circuit in phase control or half-wave control.

Diese Schaltungstechnik läßt sich allerdings bei Gleichstrom nicht anwenden aufgrund der fehlenden Frequenz.However, this circuit technology cannot be used with direct current apply due to the lack of frequency.

Kritisch bei der heutigen Technik ist die Dämpfung von Glühlampen, die mit Gleichstrom betrieben werden, mit variablen Vorschaltwiderständen oder mit vorgeschalteten Transistoren oder Längsreglern im Analogbetrieb, die so bedampfen, daß an diesen Elementen nach demThe attenuation of incandescent lamps is critical with today's technology, which are operated with direct current, with variable series resistors or with upstream transistors or series regulators in analog mode, which vaporize so that on these elements after

5 Ohmschen Gesetz erhebliche Verlustleistung als Wärme verlorengeht, die als Leistung der immer begrenzten Batteriekapazität entzogen wird.5 Ohm's law, considerable power dissipation is lost as heat, which is withdrawn as power from the always limited battery capacity.

Der Erfindung liegt die Aufgabe zugrunde, die Lampen im Batteriebetrieb zu dämpfen, ohne wesentliche Verlustleistung freizusetzen, und damit Strom zu sparen.The invention is based on the object of operating the lamps on batteries to attenuate without releasing significant power loss, and thus save electricity.

Diese Aufgabe wird dadurch gelöst, daß die Spannung im Lampenkreis durch einen Schalttransistor ein- und ausgeschaltet wird. Dies geht so schnell, daß es für das Auge nicht erkennbar ist, aber auch so langsam, daß Störungen durch Oberwellen weitgehend vermieden werden.This object is achieved in that the voltage in the lamp circuit is switched on and off by a switching transistor. This happens so quickly that it is invisible to the eye, but also like this slowly so that interference from harmonics is largely avoided.

Um die Verlustleistung nachhaltig zu minimieren, wird der Schalttransistor mit einem Puls so angesteuert, daß die Schaltung durch die senkrechten Flanken eines Rechteckpulses geschieht.In order to sustainably minimize the power loss, the switching transistor controlled with a pulse in such a way that the switching occurs through the vertical edges of a square pulse.

Die rechteckige Ansteuerung der Glühlampen zeigt, daß das Licht einer gepulsten Lampe heller empfunden wird, als das Licht einer nicht gepulsten Lampe, wenn diese mit gleichem Effektivstrom betrieben wird.The rectangular control of the incandescent lamps shows that the light from a pulsed lamp is perceived as brighter than the light from one non-pulsed lamp, if this is operated with the same effective current.

Der erzielbare Vorteil ist, daß sich mit dem beschriebenen Dimmer batteriebetriebene Glühlampen so dimmen lassen, daß Strom und damitThe advantage that can be achieved is that, with the dimmer described, battery-operated incandescent lamps can be dimmed in such a way that electricity and thus
