Abstract
Description
Gebiet der ErfindungField of the invention
Licht emittierende Dioden (LED) werden zunehmend für Beleuchtungszwecke in der Raumbeleuchtung, nachstehend Allgemeinbeleuchtung genannt, eingesetzt. Ein wesentlicher Grund hierfür ist ihre gute Lichtausbeute, d. h. die Ausbeute bei der Umwandlung von elektrischem Strom in Licht. Die Lichtausbeute von LEDs, gemessen in Lumen pro Watt elektrischer Leistung, ist größer als die von Glühlampen und Halogenglühlampen. Spezielle Hochleistungs-LEDs erreichen und übertreffen sogar die Lichtausbeute von energiesparenden Leuchtstofflampen.light emitting diodes (LEDs) are becoming increasingly used for lighting purposes in room lighting, hereafter called general lighting, used. A major reason for this is their good light output, d. H. the yield in the conversion of electric current in Light. The light output of LEDs, measured in lumens per watt of electrical Performance is greater than that of incandescent bulbs and halogen bulbs. Achieve special high performance LEDs and even exceed the luminous efficacy of energy-saving Fluorescent lamps.
Ein weiterer wesentlicher Grund ist die Lebensdauer von LEDs, die bis zu 100.000 h betragen kann. Aktuelle Hochleistungs-LEDs werden, um eine maximale Lichtausbeute zu erreichen, oft an Arbeitspunkten betrieben, bei denen ihre Lebensdauer bei 15.000 bis 30.000 Stunden liegt. Dies ist deutlich mehr als die Lebensdauer von Glühlampen und Halogenglühlampen aber auch mehr als die Lebensdauer von Leuchtstofflampen Im Gegensatz zu Leuchtstofflampen besitzen LEDs eine sehr kleine Leuchtfläche. Der Licht emittierende Halbleiterchip reicht von Dimensionen unter 1 mm2 bis zu wenigen mm2. Dies führt zu Blendungen, wenn man direkt in die LED schaut. Bei Hochleistungs-LED's besteht sogar die Gefahr der Netzhautschädigung, wenn man direkt in den Schein der LED blickt. In der Allgemeinbeleuchtung kann auf eine Verteilung des von einem LED-Leuchtmittel erzeugten Licht über entsprechende optische Elemente aus Gründen des Gesundheitsschutzes aber auch aus ästhetischen Gründen oft nicht verzichtet werden.Another major reason is the lifetime of LEDs, which can be up to 100,000 hours. Current high-power LEDs are often operated at operating points where their lifespan is 15,000 to 30,000 hours to achieve maximum light output. This is significantly more than just the life of incandescent and halogen incandescent lamps but also more than the lifetime of fluorescent lamps In contrast to fluorescent lamps, LEDs have a very small illuminated area. The light-emitting semiconductor chip ranges from dimensions of less than 1 mm 2 to a few mm 2 . This leads to glare when looking directly into the LED. With high-performance LEDs, there is even the danger of retinal damage if you look directly into the glow of the LED. In general lighting can not be dispensed with a distribution of the light generated by an LED light via corresponding optical elements for reasons of health protection but also for aesthetic reasons.
Auch wenn die Lichtausbeute bei LEDs hoch ist, wandeln LEDs einen Teil der zugeführten elektrischen Leistung in Wärme um. Wird die die Wärme nicht effektiv von Halbleiterchip weggeführt, kommt es zur Erwärmung des Halbleiterchips und damit zu einer beschleunigten Alterung oder sogar zur Zerstörung der LED. Um dies zu vermeiden ist eine gute Wärmeabfuhr bei LED-Leuchtmitteln zu gewährleisten.Also if the luminous efficacy is high for LEDs, LEDs convert a part the supplied electrical power in heat around. The heat is not effective from semiconductor chip led away, it comes to heating of the semiconductor chip and thus accelerated aging or even destruction the LED. To avoid this is a good heat dissipation to ensure LED bulbs.
Stand der TechnikState of the art
Durch LEDs kantenbeleuchtete Leuchten oder Leuchtkörper sind an sich bekannt.By LEDs edge-lit lights or luminaires are known in itself.
Kühlkörper für Hochleistungs-LED's sind an sich nicht neu. In Handel werden Hochleistungs-LED vornehmlich montiert auf Kühlkörper angeboten. Als Beispiele sind zu nennen Luxeon 1W Emitter Typ LXHL-PWO1 oder Luxeon 5W Emitter LXHL-LW6C, die auf sternförmigen Kühlkörpern angeboten werden.heatsink for high power LEDs are not new in themselves. In trade High performance LEDs are mainly mounted on heat sinks offered. Examples include Luxeon 1W emitter type LXHL-PWO1 or Luxeon 5W emitter LXHL-LW6C, which star-shaped Heatsinks are offered.
Dies führt zu einem schlankeren Aufbau des LED-Moduls und einen besseren Wärmedurchgang zum Kühlkörper.This leads to a slimmer construction of the LED module and a better heat transfer to the heat sink.

LED-Leuchtmittel können einzelne LEDs sein, die an der Einfassung der Leuchte befestigt sind. Bevorzugte LED-Leuchtmittel sind auf einer länglichen Trägerplatine aufgebrachte und kontaktierte LEDs, sogenannte LED-Streifen. Der Ort der Montage der LED-Leuchtmittel in der Einfassung soll nur der Beschränkung unterliegen, dass das vom LED-Leuchtmittel erzeugte Licht möglichst vollständig in den Lichtleiter eingespeist wird und gleichzeitig die vom LED-Leuchtmittel erzeugte Wärme zur Einfassung effektiv übertragen werden kann. Das LED-Leuchtmittel ist vorzugsweise mittig, in Bezug auf die Kante des Lichtleiters, angeordnet.LED bulbs can be single LEDs attached to the bezel of the luminaire are attached. Preferred LED bulbs are on an elongated Carrier board applied and contacted LEDs, so-called LED strip. The place of mounting the LED bulbs in the enclosure should only be subject to the restriction that the LED bulb generated light as completely as possible in the light guide is fed and at the same time generated by the LED bulb Heat can be effectively transferred to the enclosure. The LED illuminant is preferably centered with respect to the edge of the light guide, arranged.

auch oberhalb der Kante des Lichtleiters angebracht sein. In dieser
Ausführungsform ist die Kante (
In der Allgemeinbeleuchtung werden in der Regel LED-Leuchtmittel eingesetzt, die weißes Licht emittieren.

It can both White LED bulbs based on RGB technology as well blue LED bulbs can be used with a phosphor.
Hinsichtlich der Farbtemperatur der eingesetzten weißen LED-Leuchtmittel gibt es keine Beschränkung. Abhängig von der Farbtemperatur der LED-Leuchtmittel lassen sich Leuchten mit verschiedenen Farbtemperaturen gestalten.Regarding the color temperature of the white LED bulbs used there is no restriction. Depending on the color temperature The LED bulbs can be luminaires with different color temperatures shape.

Der flächige Lichtleiter ist besonders vorteilhaft, da er das konzentrierte Licht des LED-Leuchtmittels verteilt und somit Blendungen durch das LED-Leuchtmittel vermeidet.Of the planar light guide is particularly advantageous because he the concentrated light of the LED bulb spread and thus glare avoided by the LED bulb.

Im Minimalfall reicht es jedoch aus, nur eine Kante des Lichtleiters
zu beleuchten. Dies ist beispielhaft in
Der Abstrahlwinkel des eingesetzten LED-Leuchtmittels bestimmt die Effizienz mit der das vom LED-Leuchtmittel erzeugte Licht in den flächigen Lichtleiter eingespeist werden kann. Zur vollständigen Einspeisung des Lichts sollte der Abstrahlwinkel des LED-Leuchtmittels kleiner als 180°, bevorzugt kleiner als 150° und ganz bevorzugt kleiner als 120° sein.Of the Beam angle of the LED illuminant used determines the efficiency with the light generated by the LED bulb in the flat Fiber optic can be fed.
