Gattungsgemäße
Leuchtmittel sind aus der
Die Aufgabe der vorliegenden Erfindung besteht daher darin, ein Leuchtmittelmodul mit einer LED als Leuchtmittel zur Verfügung zu stellen, das die Nachteile des Standes der Technik nicht aufweist.The The object of the present invention is therefore a light-emitting module to provide with a LED as a light source, which does not have the disadvantages of the prior art.
Gelöst wird diese Aufgabe durch ein Leuchtmittelmodul mit dem Merkmal des Anspruchs 1. Vorteilhafte Ausgestaltungen und Weiterentwicklungen des erfindungsgemäßen Leuchtmittelmoduls sind Gegenstand der Unteransprüche.Solved This object is achieved by a lighting module with the feature of Claim 1. Advantageous embodiments and further developments of Inventive lamp module are the subject the dependent claims.
Das erfindungsgemäße Leuchtmittelmodul umfasst ein Gehäuse mit einem Kern aus einem Aluminium-Druckguss-Kühlkörper mit radial darauf angeordneten Kühlrippen, der gleichzeitig als Leuchtmittelhalterung vorgesehen ist. Der Aluminium-Druckguss-Kühlkörper ist zusammen mit der LED im Gehäuse integriert, das zusätzlich einen Gehäusemantel, einen Reflektor sowie ein Befestigungsring für den Reflektor umfasst. Des Weiteren sind am Gehäuse Befestigungsvorrichtungen zur Befestigung des Leuchtmittelmoduls innerhalb eines Beleuchtungssystems vorgesehen. Der Gehäusemantel ist kaminartig ausgebildet und oberhalb einer ringförmigen, durch die Kühlrippen unterteilten Öffnung angeordnet, durch die Luft unterhalb des Leuchtmittels angesaugt werden kann, die dann oberhalb des Leuchtmittels aus dem Gehäuse wieder ausströmt. Auf diese Weise kann durch natürliche Konvektion eine effektive Kühlung des Leuchtmittels erreicht werden, wobei die Luftströmung durch den kaminartigen Gehäusemantel zur Ausströmöffnung im oberen Bereich des Gehäusemantels hin kanalisiert wird.The Bulb module according to the invention comprises Housing with a core of an aluminum die-cast heat sink with radially arranged thereon cooling fins, the same time is provided as a light source holder. The die-cast aluminum heat sink is integrated with the LED in the housing, which in addition a housing shell, a reflector and a mounting ring for the reflector. Furthermore, the case Fastening devices for fastening the lamp module provided within a lighting system. The housing jacket is chimney-like and above an annular, arranged through the cooling ribs divided opening, can be sucked in through the air below the bulb, which then flows out of the housing above the luminous means again. In this way, by natural convection an effective Cooling of the bulb can be achieved, with the air flow through the chimney-like housing jacket to the outflow opening in channeled at the top of the housing shell.
Diese natürliche Konvektion kann zusätzlich noch durch einen Ventilator unterstützt werden, der oberhalb des Leuchtmittels im Gehäuse direkt unterhalb der Ausströmöffnung angeordnet ist und dort die Wärmekonvektion fördert. Der Ventilator ist bevorzugt mit Hilfe von Gummihaltern schwingungsgedämpft im oberen Teil des Gehäusemantels befestigt, ohne dabei Kontakt zum Aluminiumdruckgusskühlkörper zu haben. Dabei wird der Ventilator durch elektrische Energie angetrieben, die dem Beleuchtungssystem direkt entnommen wird.These Natural convection can be additionally through a fan can be supported, which is above the bulb in the housing directly below the discharge opening is arranged there and promotes the heat convection. The fan is preferably vibration damped by means of rubber holders attached in the upper part of the housing shell, without missing To have contact with the aluminum die-cast heat sink. The fan is powered by electrical energy, which is taken directly from the lighting system.
In einer bevorzugten Ausführung ist der Ventilator an vier Gummihaltern im Gehäusemantel befestigt, wobei eine besonders bevorzugte Ausgestaltung des Leuchtmittelmoduls vorsieht, dass die Aufhängung des Ventilators und der Gehäusemantel als ein elastisches Gummiteil ausgebildet sind, sodass die Montage der Lüftereinheit für die zusätzlich erzwungene Konvektion durch einfaches Zusammenstecken des Gehäusemantels zusammen mit dem Ventilator auf den Aluminium-Druckgusskühlkörper erfolgen kann.In In a preferred embodiment, the fan is at four Rubber holders mounted in the housing shell, with a special preferred embodiment of the lamp module provides that the Suspension of the fan and the housing jacket are formed as an elastic rubber part, so that the assembly the fan unit for the additional Forced convection by simply putting the housing shell together together with the fan on the aluminum die-cast heat sink can.
Aus Gründen der Betriebssicherheit ist am Aluminium-Druckguss-Kühlkörper vorteilhaft ein Temperaturfühler angeordnet, wobei bei einer bevorzugten Ausgestaltung des Leuchtmittelmoduls als Temperaturfühler sogenannte NTC-Fühlerelemente eingesetzt werden, bei denen es sich um stromleitende Materialien handelt, die einen negativen Temperaturkoeffizienten besitzen und deren elektrischer Widerstand mit steigender Temperatur sinkt. Mit Hilfe derartiger NTC-Fühlerelemente, die bspw. mit dem Kühlkörper verschraubt sein können, kann die Temperatur der LED überwacht werden, wodurch ein aktiver Brandschutz sowie ein aktiver Schutz der LED selber gewährleistet werden kann, wobei bspw. das System über das Fühlerelement ausgeschaltet wird, sobald die Temperaturen über 80°C ansteigen.Out Operational safety is due to the aluminum die-cast heat sink advantageous arranged a temperature sensor, wherein at a preferred embodiment of the lamp module as a temperature sensor so-called NTC sensor elements are used, in which these are conductive materials that have a negative Have temperature coefficients and their electrical resistance decreases with increasing temperature. With the help of such NTC sensor elements, the example be bolted to the heat sink can, the temperature of the LED can be monitored which results in active fire protection as well as active protection the LED itself can be guaranteed, for example, the system over the sensor element is switched off as soon as the temperatures exceed Rise to 80 ° C.
Die Kühlung des Leuchtmittelmoduls ist üblicherweise so geregelt, dass die Oberflächentemperaturen im Leuchtmittelsystem mit Ausnahme der Oberfläche der LED selber unter 60°C liegen. Die Temperaturregelung erfolgt dabei bevorzugt über das Ein- und Ausschalten des Lüfters sowie die entsprechende Einstellung der Drehzahl. Dabei kann die Temperatur der LED entweder mit einem analogen Vorschaltgerät statisch oder mit einem programmierbaren elektronischen Vorschaltgerät, das mit Hilfe eines Mikroprozessors gesteuert wird, aktiv geregelt werden.The Cooling of the lamp module is usually so regulated that the surface temperatures in the lighting system with the exception of the surface of the LED itself below 60 ° C lie. The temperature control is preferably carried out via turning the fan on and off and the corresponding one Setting the speed. The temperature of the LED can be either with an analog ballast static or with a ballast programmable electronic ballast that with Help of a microprocessor is controlled, actively regulated.
Die lichttechnischen Eigenschaften des Leuchtmittelmoduls werden im Wesentlichen auch durch den eingesetzten Reflektor bestimmt. Eine bevorzugte Ausgestaltung des erfindungsgemäßen Leuchtmittelmoduls weist einen sphärisch geformten Reflektor auf, dessen Oberfläche facettenartig aufgebaut ist, wobei bei einer besonders bevorzugten Ausgestaltung die Oberfläche zusätzlich mit einer Schutzschicht versehen ist. Besonders gute lichttechnische Eigenschaften werden dann erzielt, wenn der Reflektor mit einer Reflexionsschicht aus hochreinem Aluminium beschichtet ist, die durch eine Flash-Verdampfung von hochreinem Aluminium aus Wolframwendeln in einer Chargenvakuumbeschichtungsanlage abgeschieden wird, wobei Schichtdicken von ca. 0.25 μm aufgetragen werden.The photometric properties of the lamp module are essentially determined by the reflector used. A preferred embodiment of the luminous means module according to the invention has a spherically shaped reflector whose surface is constructed facet-like, wherein in a particularly preferred embodiment, the surface is additionally provided with a protective layer. Particularly good photometric properties are achieved when the reflector is coated with a reflective layer of high purity aluminum deposited by flash evaporation of high purity aluminum from tungsten filaments in a batch vacuum coating machine, with layer thicknesses of about 0.25 μm being applied.
Die Schutzschicht wird üblicherweise unmittelbar nach dem Aufdampfen der Reflexionsschicht ebenfalls im Vakuumzyklus der Chargenbeschichtungsanlage auf der Reflexionsschicht abgeschieden. Dazu kann bspw. Hexamethyldisiloxan in der Vakuumbeschichtungsanlage verdampft werden und unter Einwirkung einer Glühkathodenentladung bei Zugabe von Sauerstoff wird eine dichte, interferenzfreie sowie nahezu absorptionsfreie und weitgehend porenfreie Polymerschicht, deren stöchiometrische Zusammensetzung nahezu dem Siliziumdioxid entspricht, abgeschieden. Derartige Reflektoren sind im Handel erhältlich und zeichnen sich durch einen besonders hohen Wirkungsgrad in der Oberflächenreflexion aus, wobei im Vergleich zu eloxierten Systemen bis zu 15% mehr effektiv nutzbares gerichtetes Licht erzeugt wird. Die Schutzschicht aus polymerem SiO2 bewirkt aufgrund ihrer geringen Dicke (ca. 25 nm) und des günstigen Brechungsindexes nur eine unbedeutende Absenkung der Reflexion, garantiert jedoch einen effizienten Langzeitschutz der Reflexionsschicht gegenüber aggressiven Umwelteinflüssen.The protective layer is usually deposited immediately after the vapor deposition of the reflective layer also in the vacuum cycle of the batch coating machine on the reflective layer. For example, hexamethyldisiloxane can be evaporated in the vacuum coating system and, under the action of a hot cathode discharge upon addition of oxygen, a dense, interference-free and almost absorption-free and largely non-porous polymer layer whose stoichiometric composition corresponds almost to the silicon dioxide is deposited. Such reflectors are commercially available and are characterized by a particularly high efficiency in the surface reflection, compared to anodized systems up to 15% more effectively usable directional light is generated. Due to its small thickness (about 25 nm) and the favorable refractive index, the protective layer of polymeric SiO 2 only causes an insignificant lowering of the reflection, but guarantees efficient long-term protection of the reflective layer against aggressive environmental influences.
Durch die sphärisch geformten Facetten werden die Lichtstrahlen stark durchmischt, wodurch Unterschiede in der Lichtfarbe von mehreren Hundert Kelvin und Farbabweichungen vom idealen Weiß bei der jeweils eingesetzten LED kompensiert werden.By the spherically shaped facets become the light rays heavily mixed, causing differences in the light color of several One hundred Kelvin and color variations from the ideal white at the each LED used to be compensated.
Das erfindungsgemäße Leuchtmittelmodul kann in den unterschiedlichsten Beleuchtungssystemen eingesetzt werden. Besonders vorteilhafte Ausgestaltungen sehen den Einsatz in Be leuchtungssystemen mit Kardanaufhängung vor, wobei entsprechende Befestigungsvorrichtungen am Gehäuse des Leuchtmittelmoduls vorgesehen sind. Eine weitere Ausgestaltung sieht den Einsatz in auf Stromschienen aufgebauten Beleuchtungssystemen vor, wobei in diesem Fall als Befestigungsvorrichtung zur Befestigung des Leuchtmittelmoduls innerhalb des Beleuchtungssystems ein über ein Drehgelenk mit dem Gehäuse verbundenes Befestigungselement für eine Stromschiene vorgesehen ist.The Bulb module according to the invention can in the various lighting systems are used. Especially advantageous embodiments see the use in lighting systems Be with gimbal before, with appropriate fasteners are provided on the housing of the lamp module. A Another embodiment provides the use constructed on busbars Lighting systems, in which case as a fastening device for fixing the lamp module within the lighting system a via a hinge connected to the housing Fastening element is provided for a busbar.
Im Folgenden wird das erfindungsgemäße Leuchtmittelmodul anhand von Zeichnungen ausführlich erläutert. Dabei zeigenin the The following is the luminous means module according to the invention explained in detail by means of drawings. Show
