Niederspannungsdekorationsleuchte mit weißen SMD-LEDs
Description
Low voltage decorative light with white SMD LEDs

Dekorationsleuchten mit mehreren Leuchtmitteln gehören zum Stand der Technik.Decorative lights with multiple light sources are state of the art.

Es gibt sie mit Glühlampen, Glimmlampen, Miniaturleuchtstofflampen und Lichtemitterdioden (LED) als Leuchtmittel. Die Leuchtmittel können in Reihenschaltung oder Parallelschaltung angeschlossen sein. Die Erscheinungsform kann als Lichtschlange oder Lichtnetz sein. Es gibt Lichtschlangen in transparenten Kunststoffschlauchen, Leuchtmittel werden mit Fassungen und ohne Fassungen verwendet, Kontakte durcht Lot-, Quetsch- und Schraubverbindungen hergestellt. Es gibt einfarbige und mehrfarbige Leuchtmittelzusammenstellungen, welche gleichzeitig oder verschiedenzeitig angesteuert sein können, mit Netz- oder Niederspannung. Ein Großteil dieser Möglichkeiten läßt sich zB zur Weihnachtszeit genau beobachten. Augenfällig ist hierbei, daß außer den farbigen roten, gelben, grünen und blauen Leuchtmitteln ein klareres, helles weiß nicht vorkommt.They are available with incandescent lamps, glow lamps, miniature fluorescent lamps and light emitting diodes (LEDs) as light sources. The light sources can be connected in series or parallel. They can appear as a light snake or light net. There are light snakes in transparent plastic tubes, light sources are used with and without sockets, contacts are made using solder, crimp and screw connections. There are single-coloured and multi-coloured light source combinations, which can be controlled simultaneously or at different times, with mains or low voltage. Most of these possibilities can be observed closely, for example at Christmas time. It is striking that apart from the coloured red, yellow, green and blue light sources, a clearer, brighter white does not occur.

Dieses Problem kann mit dem im Schutzanspruch 3 angefühten Merkmal gelöst werden.This problem can be solved with the feature set out in claim 3.

LEDs mit weißem Licht gibt es etwa seit 1998 im Handel. Die konventionellen runden Bauformen mit Durchmessern von 3 bis 10 mm finden zur Zeit Verbreitung zB in Fahrradbeleuchtungen, Taschenlampen, als Signalleuchten in Meldetafeln etc. SMD-LEDs in TOP oder SIDE Ausführungen, welche weißes Licht emittieren, finden zB als Hintergrundbeleuchtung in Displays Verwendung. Sie zeichnen sich durch eine hohe Leuchtkraft und geringe Energieaufnahme aus. Bei einer Verwendung in einer Dekorationsleuchte der in den Schutzansprüchen beschriebenen Art, ist zB eine Dekoration von Bäumen oder Büschen mit einer Vielzahl von sehr kleinen aber dennoch hellen, weißen Lichtpunkten möglich. Hierdurch können deutlich von anderen Dekorationsleuchten unterscheidbare Akzente gesetzt werden, da das Erscheinungsbild von weißem Licht sich deutlich von dem bekannten Licht der Glühlampen und farbiger LEDs unterscheidet. Aufgrund der geringen Leistungsaufnahme können sehr feine elektrische Leiter verwendet werden. Somit sind auch netzartige Dekorationen an Zimmerdecken und Wänden sowie vor Fenstern möglich, ohne daß die elektrischen Leiter störend auffallen. Da die SMD-LED nur nach einer Seite in einem definierten öffnungswinkel strahlen, kann man jede LED in einem Stück transparenten Schrumpfschlauch einfassen, dessen Ausdehnung in Längsrichtung der beiden elektrischen Leiter etwas größer ist als die der SMD-LED. Dadurch wird eine Brechung des Lichts erreicht. Das Licht wird nun in einem deutlich größeren Winkel wahrnehmbar als in dem öffnungswinkel der LED.LEDs with white light have been commercially available since around 1998. The conventional round designs with diameters of 3 to 10 mm are currently widely used, for example, in bicycle lights, flashlights, as signal lights in message boards, etc. SMD LEDs in TOP or SIDE versions, which emit white light, are used, for example, as background lighting in displays. They are characterized by high luminosity and low energy consumption. When used in a decorative light of the type described in the protection claims, it is possible, for example, to decorate trees or bushes with a large number of very small but nevertheless bright, white points of light. This makes it possible to set accents that are clearly distinguishable from other decorative lights, since the appearance of white light is very different from the familiar light of incandescent lamps and colored LEDs. Due to the low power consumption, very fine electrical conductors can be used. This also makes it possible to create net-like decorations on ceilings and walls as well as in front of windows without the electrical conductors being conspicuous. Since the SMD LED only radiates light in one direction at a defined angle, each LED can be enclosed in a piece of transparent shrink tubing, the extension of which in the longitudinal direction of the two electrical conductors is slightly larger than that of the SMD LED. This causes the light to be refracted. The light can now be perceived at a significantly larger angle than the angle of the LED.
