Abstract
Description
Die Erfindung betrifft einen Unterwasserscheinwerfer mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to an underwater floodlight with the features of the preamble of claim 1.
Unterwasserscheinwerfer, wie sie beispielsweise in Schwimmbädern zur Beleuchtung des Schwimmbeckens verwendet werden, sind üblicherweise mit Halogenlampen ausgerüstet, die allerdings einen relativ hohen Energieverbrauch besitzen und überdies den Nachteil aufweisen, dass die Lichtausbeute in bezug auf die erforderliche Energie sowie die Lebensdauer dieser Lampen gering ist.Underwater lights, such as in swimming pools for lighting the swimming pool are used are common equipped with halogen lamps, which, however, have a relatively high energy consumption and moreover have the disadvantage that the light output with respect to the required energy and the life of these lamps low is.
Um die vorstehenden Nachteile bekannter Unterwasserscheinwerfer zu beseitigen, ist bereits vorgeschlagen worden, die Scheinwerfer statt mit Halogenlampen mit Leuchtdioden (LED) auszurüsten, denn Leuchtdioden weisen nicht nur eine wesentliche längere Lebensdauer wie Halogenlampen auf, sondern besitzen auch einen geringeren Energiebedarf und eine höhere Lichtausbeute als Halogenlampen.Around the above disadvantages of known underwater lights too has already been proposed, the headlights take place Equipped with halogen lamps with LEDs (LED), as light-emitting diodes have not just a substantial longer Lifespan as halogen lamps on, but also have a lower Energy demand and a higher Luminous efficacy as halogen lamps.
Als problematisch hat sich bei Verwendung von Leuchtdioden in bekannten Unterwasserscheinwerfern die Kühlung der Leuchtdioden erwiesen. Denn bereits bei einer Erwärmung der Leuchtdioden von 70 bis 80°C hat dieses einen signifikanten negativen Einfluss auf ihre Lebensdauer sowie auf ihre lichttechnischen Eigenschaften (Lichtstrom, Lichtfarbe, Farbkontrast etc.).When problematic when using light-emitting diodes in known underwater headlamps the cooling the light-emitting diodes proved. Because even with a warming of the LEDs from 70 to 80 ° C this has a significant negative impact on their lifespan as well as their lighting properties (luminous flux, light color, Color contrast, etc.).
Zwar wurde versucht, eine ausreichende Wärmeableitung durch Kühlung des in der Regel aus Metall bestehenden Scheinwerfergehäuses zu erzielen, doch ist die Wärmeableitung innerhalb des Gehäuses zwischen den Leuchtdioden und den Gehäusewänden relativ schlecht, da die Leuchtdioden und die mit ihnen verbundenen Elektronikbausteine aufgrund der Unterwasseranwendung des Scheinwerfers gut elektrisch isoliert sein müssen und die elektrische Isolierung eine gute Wärmeleitung verhindert.Though was trying to achieve adequate heat dissipation by cooling the usually made of metal headlight housing to achieve, but is the heat dissipation inside the case between the light emitting diodes and the housing walls relatively poor, as the Light-emitting diodes and their associated electronic components due the underwater application of the headlamp well insulated electrically have to be and the electrical insulation prevents good heat conduction.
Der Erfindung liegt die Aufgabe zugrunde, einen Leuchtdioden verwendenden Unterwasserscheinwerfer anzugeben, bei dem die Leuchtdioden auf einfache Weise durch das den Scheinwerfer umgebende Wasser gut gekühlt werden, so dass sie sich auch bei höheren Leistungen nicht unzulässig erwärmen.Of the Invention is based on the object using a light-emitting diodes Submit underwater lights, in which the LEDs on easy way to be well cooled by the water surrounding the headlamp, so that they are also higher Do not heat services inappropriately.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.These The object is achieved by the Characteristics of claim 1 solved. Further, particularly advantageous embodiments of the invention reveal the dependent claims.
Die Erfindung beruht im wesentlichen auf dem Gedanken, die Leuchtdioden – anders als bei bekannten Anordnungen – nicht oder nicht nur rückseitig (d. h. sockel- bzw. platinenseitig) mit den Gehäusewänden wärmeleitend zu verbinden, sondern vor allem eine wärmeleitende Verbindung zwischen dem Fensterbereich des Gehäuses und den diesen zugewandten Bereichen der Leuchtdioden zu schaffen. Dabei sind mindestens die vorderen Bereiche der Leuchtdioden direkt oder über ein wärmeleitendes Zwischenstück mit dem Material des Fensterbereiches (in der Regel Glas oder Kunststoff) gut wärmeleitend verbunden, wobei es sich bei dem wärmeleitenden Zwischenstück beispielsweise um eine wärmeleitende Vergussmasse handeln kann.The The invention is based essentially on the idea that light-emitting diodes - different as in known arrangements - not or not just on the back (ie socket or platinum side) to connect with the housing walls heat-conducting, but before all a thermally conductive Connection between the window portion of the housing and facing this To create areas of light emitting diodes. At least the front areas of the LEDs directly or via a heat-conducting spacer with the Material of the window area (usually glass or plastic) good thermal conductivity connected, wherein it is in the heat-conducting intermediate piece, for example a thermally conductive Casting compound can act.
Vorzugsweise sind die Leuchtdioden auf einem gemeinsamen Träger (in der Regel einer Platine) befestigt, welcher wärmeleitend mit dem Gehäuse verbunden ist, so dass zusätzlich zur Wärmeableitung über den Fensterbereich auch eine Wärmeableitung über die Gehäusewände und den Träger erfolgen kann.Preferably are the LEDs on a common carrier (usually a board) attached, which conducts heat with the housing is connected, so in addition for heat dissipation over the Window area also dissipates heat over the Housing walls and the carrier can be done.
Das Gehäuse des Unterwasserscheinwerfers kann beispielsweise aus Rotguss, einer Aluminiumlegierung oder einer V4A-Stahllegierung bestehen.The casing the underwater headlamp, for example, from gunmetal, a Aluminum alloy or a V4A steel alloy.
Um einen möglichst einfachen Aufbau des erfindungsgemäßen Unterwasserscheinwerfers zu erhalten, hat es sich als vorteilhaft erwiesen, wenn die Außenkontur des Gehäuses derart gewählt ist, dass es in das Gehäuse eines vorhandenen Unterwasserscheinwerfers mit Halogenstrahlern nach Entfernen dieser Strahler einsetzbar ist.Around one possible simple structure of the underwater headlight according to the invention To obtain, it has proved to be advantageous if the outer contour of the housing chosen like that is that in the case an existing underwater floodlight with halogen spotlights can be used after removing these emitters.
