Abstract

The tube has a tubular body (1) made of glass or plastic, and a carrier strip (2) pushed into the tubular body. The strip comprises a bend (6) in longitudinal direction, where a tip of the bend is directed away from a housing of a fluorescent tube lamp in a state in which the tube is mounted in the lamp. A set of LEDs (3) is arranged on a side of the strip, where the side is directed away from the housing in the state. The body comprises two half-shells that are made of glass or plastic and aluminum, respectively. One of the half-shells comprises a corrugated surface. An independent claim is also included for a fluorescent tube lamp comprising a holder element.

Description

Die altbekannten Leuchtstoffröhren wurden in letzter Zeit in der Weise weiterentwickelt, dass an Stelle einer leichtenden Gasfüllung so genannte LED's (Light Emitting Diode) oder SMD's (Surface Mounted Device) (3) als Leuchtmittel verwendet werden.The well-known fluorescent tubes have been recently developed in such a way that instead of a light gas filling so-called LED's (Light Emitting Diode) or SMD's (Surface Mounted Device) ( 3 ) can be used as a light source.

Durch die neue Technik wird eine bessere Leuchtkraft bei deutlich geringerem Stromverbrauch erzielt.The new technology achieves better luminosity with significantly lower power consumption.

Bei den neuen Leuchtmitteln handelt es sich um kleinste Elemente, (3) die auf einem flachen Trägerstreifen (2) montiert sind, der in die Leuchtröhre (1) oder eine Lampe eingschoben wird.The new bulbs are the smallest elements, ( 3 ) on a flat carrier strip ( 2 ) are mounted in the arc tube ( 1 ) or a lamp is inserted.

Im Betrieb wirkt sich allerdings die Wärme, die von den euchtdioden (3) ausgeht, nachteilig, das heißt leistungsminderd aus. Mit ansteigender Temperatur in der Röhre (4) oder Lampe steigt außerdem auch der Stromverbrauch.In operation, however, the heat that is absorbed by the light-emitting diodes ( 3 ), disadvantageous, that is performance reduced. With increasing temperature in the tube ( 4 ) or lamp also increases the power consumption.

Es ist deshalb das Ziel der Erfindung, auf einfache Weise diesen Nachteil auszugleichen und die Wärmeentwicklung zu kompensieren.It is therefore the object of the invention to easily compensate for this disadvantage and to compensate for the evolution of heat.

Dieses Ziel wird dadurch erreicht, dass neben den LED's bzw SMD's (3) Dioden (6) plaziert werden, bei denen der Stromdurchfluss in umgekehrter Richtung erfolgt, so dass sie kühlen, anstatt zu leuchten und dabei zu heizen.This goal is achieved in that in addition to the LED's or SMD's ( 3 ) Diodes ( 6 ), where the flow of current is reversed so that they cool rather than glow and heat up.

Gegenüber dem Stand der Technik ergibt sich hierdurch der Vorteil, dass die Röhren (4) bzw Lampen nicht mit komplizierten und teueren Wärme-Abstrahlungs-Strukturen (5) versehen werden müssen, die außerdem Staubfänger sind und von denen Brandgefahr ausgeht.Compared to the prior art, this results in the advantage that the tubes ( 4 ) or lamps not with complicated and expensive heat radiating structures ( 5 ), which are also dust collectors and pose a fire hazard.

Sofern die Kühldioden (6) auf der Rückseite der im Hauptpatent beschriebenen Trägerplatte (2) plaziert werden, wird der Kühleffekt erzielt, ohne dass Platz fpr die LED's oder SMD's (3) verloren geht.If the cooling diodes ( 6 ) on the back of the carrier plate described in the main patent ( 2 ), the cooling effect is achieved without leaving space for the LED's or SMD's ( 3 ) get lost.
