Abstract
Description
Die Erfindung betrifft eine Lampe, insbesondere Positionslampe für ein Flugzeug, welche eine mit einer konstanten Lichtstärke strahlende Lichtquelle aufweist.The invention relates to a lamp, in particular position lamp for an airplane, which is a radiant with a constant light intensity Has light source.
Lampen der vorstehenden Art sind als Positionslampen für Flugzeuge bekannt. Sie sind an den Tragflächen von Flugzeugen angebracht. Die an der linken Tragfläche befindliche Lampe muss dabei in einem festgelegten Winkel mit rotem Licht und die an der rechten Tragfläche im gleichen Winkel mit grünem Licht strahlen. Ähnliche Positionslampen sind bei Schiffen vorgeschrieben.Are lamps of the above type as position lamps for Aircraft known. They are attached to the wings of aircraft. The one on the left wing lamp must be at a fixed angle with red Light and the one on the right wing at the same angle green Shine light. Similar Position lights are mandatory for ships.
Solche Positionslampen erlauben es einem Beobachter, im Dunklen den Kurs des Flugzeugs zu erkennen. Sie haben wegen ihrer verhältnismäßig geringen Helligkeit und ihrer konstanten Leuchtkraft jedoch den Nachteil, relativ wenig aufzufallen. Deshalb ist es bei Flugzeugen üblich, zusätzlich zu den Positionslampen ein Blitzlicht vorzusehen. Dabei handelt es sich üblicherweise um eine Blitzröhre. Solche Blitzröhren sind relativ teuer und erfordern einen hohen Energiebedarf. Bekannt ist es auch, ein Blitz- oder Blinklicht dadurch zu erzeugen, dass eine Blende um eine Lichtquelle konstanter Leuchtkraft rotiert, was jedoch relativ aufwändig ist.Such position lamps allow it an observer to see the course of the plane in the dark. You have because of their relatively low Brightness and their constant luminosity, however, the disadvantage relatively little noticed. That is why it is common on airplanes, in addition to to provide a flashing light for the position lamps. This is what it is about usually around a flash tube. Such flash tubes are relatively expensive and require a high level of energy. Known is it also to generate a flash or flashing light by that an aperture rotates around a light source of constant luminosity, what however relatively complex is.
Der Erfindung liegt das Problem zugrunde, eine Lampe der eingangs genannten Art zu entwickeln, welche mit einer gleichmäßigen Helligkeit leuchtet, durch zusätzliche Mittel jedoch mehr Aufmerksamkeit zu erregen vermag als ein solches Gleichlicht.The invention is based on the problem, a To develop lamp of the type mentioned, which with a uniform brightness lights up, by additional Means, however, can attract more attention than such a constant light.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass die Lichtquelle durch mehrere Leuchtdioden gebildet ist und dass die Leuchtdioden mit einer Spannungsversorgung verbunden sind, welche eine konstante, zu einem gleichmäßigen Leuchten der Leuchtdioden führende Gleichspannung und in regelmäßigen Abständen kurze Spannungsspitzen zum Erzeugen jeweils eines Lichtblitzes der Leuchtdioden liefert.This problem is solved according to the invention solved, that the light source is formed by several light emitting diodes and that the LEDs are connected to a power supply, which a constant, to a uniform glow leading the light emitting diodes DC voltage and short at regular intervals Voltage peaks for generating a flash of light from the light emitting diodes supplies.
Eine solche Lampe ist sowohl Gleichlicht als auch Blitzlicht. Deshalb kann man bei einem Flugzeug ein separates Blitzlicht zusätzlich zu den Positionslampen einsparen. Da die Blitze beispielsweise nur alle 1 bis 2 Sekunden erscheinen und nur 30 ms andauern, sind die Leuchtdioden in der Lage, die hierfür erforderliche, kurzfristige Überspannung ohne unerwünschte Verkürzung ihrer Lebensdauer zu verkraften. Da die Lichtquelle durch Leuchtdioden gebildet ist, benötigt sie nur wenig elektrische Energie, so dass sie durch eine Batterie geringer Kapazität betrieben werden kann, was insbesondere für Ultraleichtflugzeuge vorteilhaft ist.Such a lamp is both constant light as well as flash light. Therefore you can have a separate one on an airplane Flash light additionally save on position lights. Because the flashes, for example, only appear every 1 to 2 seconds and last only 30 ms, they are LEDs are able to provide the short-term overvoltage required for this without unwanted shortening to cope with their lifespan. Because the light source by LEDs is formed they have little electrical energy so they're powered by a battery low capacity can be operated, which is particularly advantageous for ultralight aircraft is.
Die erfindungsgemäße Lampe benötigt für den Einsatz als Positionslampe keinen speziellen Reflektor und keine Blende zur Begrenzung des Bereiches ihres abgestrahlten Lichtes, wenn gemäß einer vorteilhaften Weiterbildung der Erfindung die Leuchtdioden zur Abstrahlung des Lichtes in einem festgelegten Winkel ausgebildet und ausgerichtet sind.The lamp according to the invention requires for use as a position lamp no special reflector and no aperture to limit the range of their emitted light when according to a advantageous development of the invention, the light emitting diodes for radiation of the light are formed and aligned at a fixed angle.
Die Lampe ist besonders erschütterungsunempfindlich, wenn die Leuchtdioden auf einer Platine angeordnet und durch Vergießen von einem transparenten Material vollständig umschlossen sind.The lamp is particularly insensitive to vibrations, if the LEDs are arranged on a circuit board and by potting are completely enclosed in a transparent material.
