Abstract
Description
Die Erfindung betrifft eine LED-Signalleuchte mit Wärmeableitanordnung.The The invention relates to an LED signal lamp with heat dissipation arrangement.
Ampelleuchten, die spezielle Signalleuchten darstellen, werden an Straßenkreuzungen installiert, um Fahrzeugen oder Fußgängern anzuzeigen, wann sie fahren bzw. gehen können und wann sie stehen bleiben müssen. Eine Ampelleuchte verfügt im Allgemeinen über die drei Farben Rot, Gelb und Grün. Diese Farben werden herkömmlicherweise durch entsprechende Glühlampen erzeugt, die durch farbige Lampenschirme abgedeckt sind. Jedoch werden derartige herkömmliche Ampelleuchten bei starkem Sonnenlicht nur schwer erkennbar, oder sie werden durch Regen beeinträchtigt, so dass also die Wetterbedingungen direkt ihre Erkennbarkeit beeinflussen.Traffic Lights, which represent special signal lights, are at intersections installed to show vehicles or pedestrians when they are can drive or go and when they have to stop. A traffic light has generally over the three colors red, yellow and green. These Colors are traditionally through appropriate light bulbs generated, which are covered by colored lampshades. however become such conventional Traffic lights in strong sunlight difficult to see, or they are affected by rain, so that the weather conditions directly affect their visibility.
Um diese Mängel zu überwinden, werden für moderne Signalleuchten, wie Ampelleuchten, Leuchtdiode (LEDs) ersetzt, die sehr hell sind, dabei jedoch wenig Energie verbrauchen und eine hohe Leuchteffizienz und eine lange Lebensdauer zeigen. Da sich mit Hochleistungs-LEDs viel hellere Leuchten als wie mit herkömmlichen Glühlampen erzeugen lassen, ist bei ihrer Verwendung die Sicherheit durch bessere Erkennbarkeit deutlich verbessert.Around these defects to overcome, be for modern Signal lights, such as traffic lights, light-emitting diode (LEDs) replaced, the are very bright, but consume little energy and one high luminous efficiency and a long service life. That I with high power LEDs much brighter lights than with conventional ones lightbulbs generate better safety when using it Recognizability significantly improved.
Um die benötigte hohe Helligkeit zu erzielen, sind bei aktuellen LED-Signalleuchten typischerweise 125 bis 188 LEDs vorhanden. Diese erzeugen viel Wärme, so dass eine Wärmeableitanordnung zu verwenden ist, um die Wärme abzuführen und die LEDs auf relativ niedriger Temperatur zu halten. Insbesondere aufgrund der Wärmeableitanordnung kommt es jedoch zwischen einigen der vielen LEDs zu Kurzschlüssen, wodurch die Leuchte, in der sie angeordnet sind, dunkler wird, und damit die Verkehrssicherheit wieder beeinrächtigt wird, wenn eine solche Signalleuchte als Ampel leuchte verwendet wird. Bei bekannten Konstruktionen wird eine Aluminiumplatte zum Ableiten der durch die LEDs erzeugten Wärme verwendet, jedoch ist dabei der Wärmeableiteffekt wegen der nicht all zu guten Wärmeleitfähigkeit von Aluminium eingeschränkt.Around the needed high brightness are achieved with current LED signal lights typically 125 to 188 LEDs available. These generate a lot of heat, so that a heat dissipation arrangement to use is to heat dissipate and keep the LEDs at a relatively low temperature. Especially due to the heat dissipation arrangement However, there are shorts between some of the many LEDs, causing the light in which they are arranged gets darker, and with it traffic safety is compromised again, if such Signal light is used as traffic light light. In known constructions is an aluminum plate for dissipating the generated by the LEDs Heat used however, the heat dissipation effect is due to this not all that good thermal conductivity limited by aluminum.
Der Erfindung liegt die Aufgabe zugrunde, eine LED-Signalleuchte mit Wärmeableitanordnung zu schaffen, bei der die durch die verwendeten LEDs erzeugte Wärme gut abgeleitet wird.Of the Invention is based on the object, an LED signal light with Heat dissipation arrangement to create, in which the heat generated by the LEDs used well is derived.
Diese Aufgabe ist durch die LED-Signalleuchte gemäß dem beigefügten Anspruch 1 gelöst. Es ist eine einzelne Lichtemissionseinheit als Lichtemissionsquelle der Signalleuchte verwendet, und diese Lichtemissionseinheit verfügt über eine an ihrem Umfang angeordnete Wärmeableitanordnung zum Ableiten von Wärme nach außen. Es sind also nicht nur die mehreren Lichtemissionseinheiten, wie sie bei herkömmlichen Signalleuchten verwendet werden, durch eine einzelne Lichtemissionseinheit ersetzt, sondern es ist auch ein spezielles Design der Wärmeableitanordnung verwendet.These The object is achieved by the LED signal lamp according to the appended claim 1 solved. It is a single light emission unit as a light emission source the signal light is used, and this light emission unit has a arranged on its circumference Wärmeableitanordnung to Dissipation of heat outward. So it's not just the multiple light emission units like them at conventional Signal lights are used, replaced by a single light emission unit, but it is also a special design of the heat dissipation assembly used.
Die Erfindung wird nachfolgend anhand von durch Figuren veranschaulichten Ausführungsformen näher erläutert.The Invention will now be illustrated by figures embodiments explained in more detail.
