Description
Die Erfindung betrifft einen Dioden-Beleuchtungskörper nach dem Oberbegriff des Schutzanspruchs 1.The The invention relates to a diode lighting body according to the preamble of Protection claim 1.
Als Beleuchtungskörper für Vitrinen oder Wohnräume wurden bisher überwiegend Glühlampen oder Leuchtstoffröhren verwendet. Wegen ihrer geringen Lichtausbeute werden Glühlampen jedoch immer häufiger durch andere Lampen ersetzt. Leuchtstoffröhren haben zwar eine höhere Lichtausbeute, flackern jedoch oft beim Ein- und Ausschalten, es sei denn, es werden teure Starter verwendet. Als ein weiterer alternativer Beleuchtungskörper werden seit vielen Jahren Halogen-Lampen eingesetzt. Sie haben vor allem eine lange Lebensdauer, strahlen aber sehr viel Wärme ab. Anders als Glühlampen oder Leuchtstofflampen werden Halogen-Lampen oft als Niederspannungslampen betrieben, d. h. sie werden nicht direkt an die 220 V-Netzspannung gelegt.When lighting for showcases or living spaces have been prevalent so far lightbulbs or fluorescent tubes used. Because of their low light output are incandescent but more and more often replaced by other lamps. Although fluorescent tubes have a higher light output, however, often flicker on and off, unless it will used expensive starter. As another alternative lighting fixture since used many years ago halogen lamps. First of all, you have one Long life, but radiate a lot of heat. Unlike light bulbs or Fluorescent lamps are often called halogen lamps as low voltage lamps operated, d. H. they will not be connected directly to the 220 V mains voltage placed.
Als besonders effizient haben sich LEDs (Light Emitting Diodes) erwiesen, die es inzwischen auch als OLEDs (Organic Light Emitting Diodes) gibt. Bei gleicher Lichtabgabe benötigen sie bis zu 90% weniger an elektrischer Energie als Glühlampen. Außerdem haben sie eine wesentlich längere Lebensdauer (ca. 50.000 Betriebsstunden). LEDs werden auch in Bildschirme von LCD-Fernsehern eingebaut (LCD = Liquid Crystal Display), weil sie leicht miniaturisierbar sind. LEDs sind elektronische Halbleiterkristalle. Fließt Strom durch sie hindurch, geben sie – je nach Beschaffenheit der Halbleiterelemente – Licht in den Farben Rot, Grün, Gelb oder Blau ab. Sie sind deshalb besonders als Signallichter geeignet. Seit 1990 können mit Hilfe einer internen gelblich fluoreszierenden Leuchtschicht blau leuchtende Dioden auch zum Abstrahlen von weißem Licht gebracht werden, was eine weitere Anwendung der LEDs ermöglicht. Überwiegend werden aus mehreren LEDs so genannte LED-Module zusammengefügt. Gab es früher fast nur kaltweißes Licht (Lichtfarbe > 4500 K), sind heute auch warmweiße oder neutralweiße LEDs erhältlich (2800 bis 3800 K), mit einem Farbwiedergabeindex (CRI = Colour Randering Index) > 90. Dieser Farbwiedergabeindex ist höher als bei handelsüblichen MR11- oder MR16-Halogenlampen. Die LED strahlen vernachlässigbar Infrarotlicht aus, daher eignen sich diese LED-Lichtquellen insbesondere für die Beleuch tung wärmeempfindlicher Materialien bzw. Ausstellungsgut wie zum Beispiel Lebensmitteln, Pflanzen etc.When LEDs (Light Emitting Diodes) have proven to be particularly efficient meanwhile also known as OLEDs (Organic Light Emitting Diodes) gives. With the same light output they need up to 90% less of electrical energy as light bulbs. Furthermore they have a much longer life Lifetime (about 50,000 operating hours). LEDs are also in screens from LCD TVs installed (LCD = Liquid Crystal Display), because they are easily miniaturized. LEDs are electronic semiconductor crystals. flows Power through them, they give - depending on the nature of Semiconductor elements - light in the colors red, green, Yellow or blue off. They are therefore especially as signal lights suitable. Since 1990 can with the help of an internal yellowish fluorescent luminescent layer blue-emitting diodes also for emitting white light be brought, which allows a further application of the LEDs. Mostly For example, so-called LED modules are assembled from several LEDs. Gave it earlier almost only cold white Light (light color> 4500 K), are also warm white today or neutral white LEDs available (2800 to 3800 K), with a Color Rendering Index (CRI = Color Randering Index)> 90. This Color rendering index is higher as with commercial MR11 or MR16 halogen lamps. The LED radiate negligible Infrared light, therefore, these LED light sources are particularly suitable for the Lighting device is more sensitive to heat Materials or exhibits such as food, Plants etc.
Obwohl LEDs eine sehr lange Lebensdauer haben, kann diese Lebensdauer noch durch optimierte Kühlung verlängert werden. Anders als bei Glühlampen ist die Lebensdauer bei LEDs nicht durch einen Bruch der Wendel beendet, sondern die Leuchtkraft der LEDs nimmt kontinuierlich ab, so dass man die Lebensdauer definieren muss, z. B. wenn die Leuchtkraft 50% der ursprünglichen Leuchtkraft erreicht hat.Even though LEDs have a very long life, this life can still through optimized cooling extended become. Unlike light bulbs the lifetime of LEDs is not due to a break in the coil but the luminosity of the LEDs is steadily decreasing, so you have to define the life, z. B. when the luminosity 50% of the original luminosity has reached.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Lichtquelle zu schaffen, die klein ist und bei großer Leuchtkraft oder Lichtausbeute (W/m2) und natürlicher hoher Farbwiedergabe eine wesentlich längere Lebensdauer bei geringem Energieverbrauch im Vergleich zu Halogenlampen aufweist.The invention is therefore an object of the invention to provide a light source that is small and with high luminosity or luminous efficacy (W / m 2 ) and natural high color rendering has a much longer life with low energy consumption compared to halogen lamps.
Diese Aufgabe wird gemäß den Merkmalen des Schutzanspruchs 1 gelöst.These Task is performed according to the characteristics of Protection claim 1 solved.
Der mit der Erfindung erzielte Vorteil besteht insbesondere darin, dass Beleuchtungen von Vitrinen und Schaufenstern auf einfache Weise möglich sind. Durch einen standardisierten Sockel ist gewährleistet, dass auch eventuell schon vorhandene Halogenlampen einfach ausgetauscht werden können.Of the obtained with the invention advantage is in particular that Illuminations of showcases and shop windows in a simple way possible are. By a standardized base is guaranteed that also possibly Already existing halogen lamps can be easily replaced.
