Description
Die Erfindung bezieht sich auf eine Leuchte, insbesondere Strassenleuchte, die als Leuchtmittel mehrere LED's aufweist, die auf Trägerflächen verteilt angeordnet und in Richtung der zu beleuchtenden Fläche ausrichtbar sind.
Um die Vorteile von LED's auch für Aussenleuchten auszunützen, wurden schon zahlreiche Vorschläge gemacht. So ist in der DE 102007/053790 B3 eine Leuchte der eingangs genannten Art beschrieben, bei der zur Erzielung einer gewünschten Leuchtendichteverteilung oder Beleuchtungsstärkeverteilung auf der zu beleuchtenden Fläche die LED-Trägerfläche gewölbt ist.
Nachteilig bei einer solchen Anordnung ist, dass die jeweilige Wölbung nur für eine bestimmte Fläche gilt, die zu beleuchten ist. Bei einer anderen Fläche stimmt die Leuchtendichteverteilung bzw. Beleuchtungsstärkeverteilung nicht.
In der WO 2006/060905 AI ist eine Leuchte beschrieben, bei der die LED's auf zwei schwenkbar zueinander angeordneten Platten befestigt sind. Durch Verschwenken der Platten gegeneinander kann die Beleuchtungsrichtung bzw. Beleuchtungsstärke verändert werden.
Eine genaue Anpassung an die jeweils zu beleuchtenden Flächen ist jedoch auch mit dieser bekannten Leuchte nicht möglich.
Die Erfindung hat es sich zum Ziel gesetzt, insbesondere mittels den derzeit am Markt befindlichen stärksten Hochleistungs-LED 's eine Leuchte zu schaffen, mit der eine Anpassung sowohl an die zu beleuchtende Fläche als auch an die gewünschte Leuchtenhöhe möglich ist, sodass diese Fläche optimal ausgeleuchtet werden kann.
Erreicht wird dieses Ziel dadurch, dass die LED's auf mehreren übereinander liegenden Trägerringen angeordnet sind, die in Horizontalebenen verdrehbar sind, wobei die Trägerflächen für die LED's verschiedene Neigungen besitzen. Durch die erfindungsgemässe Anordnung von horizontal verdrehbaren LEDTrägerringen ergibt sich die Möglichkeit, jedes vorgegebene Leuchtfeld durch entsprechende Einstellung der LED-Trägerringe bei der Montage optimal auszuleuchten. Es besteht auch die Möglichkeit, bei bereits montierten Leuchten einer geänderten Ausleuchtungsfläche zu entsprechen.
Derzeit wird noch jedes LED entsprechend seiner Anordnung für "Fernlichtoder Nahbereich" mit handelsüblichen Reflektoren der verschiedensten Abstrahlwinkel z.B. + - 7[deg.] /+ - 13[deg.] usw. versehen.
Bei einer zweckmässigen Ausführungsform der Erfindung haben die Trägerringe verschiedenen, den Neigungen entsprechenden (=Leuchtenhöhe), nach unten zu abnehmenden Durchmesser. Dadurch entsteht eine kegelähnliche Form der Leuchte. (Pyramidenstumpf)
LED's entwickeln verhältnismässig viel Wärme und es ist daher erfindungsgemäss vorgesehen, dass die Trägerringe als Kühlkörper mit wenigstens einem im Zentrum vertikalen, im Kopf oben horizontalen Abzugkanal für die abzuführende Wärme ausgebildet sind.
Nachstehend ist die Erfindung anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher beschrieben, ohne auf diese Beispiele beschränkt zu sein. Dabei zeigen: Fig. 1 in schaubildlicher Ansicht schräg von unten eine erfindungsgemässe Leuchte;
Fig. 2 in vergrössertem Massstab den Leuchtenkörper nach Fig. 1 ;
Fig. 3 eine Draufsicht auf einen oberen Trägerring des Leuchtenkörpers nach den Fig. 1 und 2;
Fig. 4 einen Schnitt nach der Linie A - A in Fig. 3; Fig. 5 einen Schnitt nach der Linie B - B in Fig. 3;
Fig. 6 einen Schnitt nach der Linie C - C in Fig. 3; Fig. 7 eine Draufsicht auf einen unteren Trägerring des Leuchtenkörpers nach den
Fig. 1 und 2; Fig. 8 einen Schnitt nach der Linie A - A in Fig. 7; Fig. 9 einen Schnitt nach der Linie B - B in Fig. 7; Fig. 10 einen Schnitt nach der Linie C - C in Fig. 7.
Gemäss Fig. 1 ist auf einem Ausleger 1 ein Leuchtengehäuse 2 befestigt, in dem ein Leuchtenkörper 3 angeordnet ist.
Dieser Leuchtenkörper 3 besteht gemäss Fig. 2 aus einer Anzahl von
Trägerringen 4, 5, 6 und 7 für LED's 8 und Reflektoren 10. Die Trägerringe 4, 5, 6 und 7 sind in Horizontalebenen verdrehbar. Die LED's 8 sind auf Trägerflächen 9 angeordnet, die verschiedene Neigungen besitzen, (entsprechend den Abmassen des Leuchtfeldes bzw. der Leuchtenhöhe)
In Fig. 4 ist der Trägerring 4 dargestellt und aus den verschiedenen Schnitten ergibt sich der unterschiedliche Neigungswinkel [alpha] 41, [alpha] 42 und [alpha] 43 einzelner Trägerflächen 94^ 942 und 943.
Für den in Fig. 7 dargestellten Trägerring 7 gilt ähnliches: die Neigungswinkel [alpha] 71, [alpha] 72 und [alpha] 73 auf den Trägerflächen 9 71, 972 und 9 3 sind jeweils verschieden.
Um die sich bildende Wärme abführen zu können, sind die Trägerringe als Keilkörper mit wenigstens einem im Zentrum vertikalen Abzugkanal 12 und wenigstens einem horizontalem Abzugkanal 13 versehen.
Im Ausleger 1 (Fig. 1) sind drei Stromversorgungen 111, 112 und II3 untergebracht. Jede dieser Stromversorgungen ist wenigstens einer LED-Kette zugeordnet. Die Leuchte kann dadurch entsprechend der Anzahl der Stromversorgungen in verschiedene Helligkeitsbereiche eingestellt werden.
The invention relates to a lamp, in particular street lamp, which has a plurality of LED's as light source, which are arranged distributed on support surfaces and in the direction of the surface to be illuminated can be aligned.
In order to exploit the advantages of LEDs for outdoor lighting, numerous proposals have already been made. For example, DE 102007/053790 B3 describes a luminaire of the type mentioned in the introduction, in which the LED support surface is arched on the surface to be illuminated in order to achieve a desired luminous density distribution or illuminance distribution.
A disadvantage of such an arrangement is that the respective curvature applies only to a certain area, which is to be illuminated. For another surface, the luminance distribution or illuminance distribution is not correct.
In WO 2006/060905 AI a lamp is described in which the LEDs are mounted on two pivotally arranged to each other plates. By pivoting the plates against each other, the lighting direction or illuminance can be changed.
However, an exact adaptation to the respective surfaces to be illuminated is not possible with this known lamp.
The invention has set itself the goal, in particular by means of the currently on the market located strongest high-performance LED's to create a lamp with which an adaptation to both the surface to be illuminated and to the desired luminaire height is possible, so that this area optimally can be illuminated.
This goal is achieved in that the LEDs are arranged on a plurality of superimposed support rings which are rotatable in horizontal planes, wherein the support surfaces for the LED's have different inclinations. The inventive arrangement of horizontally rotatable LED support rings gives the possibility to optimally illuminate each predetermined light field by appropriate adjustment of the LED support rings during assembly. It is also possible to comply with already installed lights of a modified illumination area.
At the present time, every LED according to its arrangement for "high-beam or near-field" is also equipped with commercially available reflectors of a wide variety of emission angles, e.g. + - 7 [deg.] / + - 13 [deg.] Etc.).
In an expedient embodiment of the invention, the support rings have different, the inclinations corresponding (= height of the luminaire), down to decreasing diameter. This creates a cone-like shape of the lamp. (Truncated pyramid)
LED's develop relatively much heat and it is therefore provided according to the invention that the support rings are formed as a heat sink with at least one vertical in the center, in the top horizontal discharge duct for the dissipated heat.
The invention will be described in more detail below with reference to an embodiment shown in the drawings, without being limited to these examples. 1 is a diagrammatic view obliquely from below a lamp according to the invention;
Fig. 2 in an enlarged scale the lamp body of Fig. 1;
Fig. 3 is a plan view of an upper support ring of the lamp body according to Figures 1 and 2.
Fig. 4 is a section along the line A - A in Fig. 3; 5 shows a section along the line B - B in Fig. 3.
Fig. 6 is a section along the line C - C in Fig. 3; Fig. 7 is a plan view of a lower support ring of the lamp body after the
Fig. 1 and 2; Fig. 8 is a section along the line A - A in Fig. 7; 9 shows a section along the line B - B in Fig. 7. 10 is a section along the line C - C in Fig. 7.
According to Fig. 1, a lamp housing 2 is fixed on a boom 1, in which a lamp body 3 is arranged.
This lamp body 3 is shown in FIG. 2 of a number of
Support rings 4, 5, 6 and 7 for LEDs 8 and reflectors 10. The carrier rings 4, 5, 6 and 7 are rotatable in horizontal planes. The LED's 8 are arranged on support surfaces 9, which have different inclinations, (corresponding to the dimensions of the light field or the luminaire height)
In Fig. 4, the support ring 4 is shown and from the different sections results in the different inclination angle [alpha] 41, [alpha] 42 and [alpha] 43 individual support surfaces 94 ^ 942 and 943rd
For the support ring 7 shown in Fig. 7, the same applies: the inclination angles [alpha] 71, [alpha] 72 and [alpha] 73 on the support surfaces 9 71, 972 and 9 3 are each different.
In order to be able to dissipate the forming heat, the carrier rings are provided as a wedge body with at least one vertical discharge duct 12 in the center and at least one horizontal discharge duct 13.
In the boom 1 (Fig. 1) three power supplies 111, 112 and II3 are housed. Each of these power supplies is associated with at least one LED string. The luminaire can thereby be adjusted according to the number of power supplies in different brightness ranges.
