Abstract

The lighting system used a number of light emitting diodes, LED, [3] that are mounted in parallel groups on either side of a triangular shaped reflector [2]. The reflector has an included angle of 90 degrees and the light is reflected to provided a broad parallel beam.

Description

Die Erfindung bezeiht sich auf eine Beleuchtungseinrichtung gemäß Oberbegriff des Anspruchs 1.The Invention refers to a lighting device according to the preamble of claim 1.

Da heute helle Leuchtdioden sehr verbreitet sind, ist das Problem ihrer Benutzung in verschiedenen Beleuchtungseinrichtungen sehr aktuell. Die Leuchtkraft einer Leuchtdiode ist gering, vergleichbar mit der Leuchtkraft einer Taschenlampe weswegen man in einer kräftigen Beleuchtungsvorrichtung viele gleiche Leuchtdioden auf einer gemeinsamen Platte anordnet.There bright light emitting diodes are very common today, the problem is theirs Use in various lighting devices very up to date. The luminosity of a light emitting diode is low, comparable to the Luminosity of a flashlight why you in a powerful lighting device arranges many identical LEDs on a common plate.

In der Regel platziert man dabei einige Leuchtdioden auf einer gemeinsamen Platte so, dass die Strahlung jeder Leuchtdiode in der gemeinsamen Richtung, also in Richtung der Strahlung der ganzen Vorrichtung, gerichtet ist. Um eine große Leuchtkraft zu bekommen, braucht man daher eine große Platte.In As a rule, one places some LEDs on a common one Plate so that the radiation of each light emitting diode in the common direction, So in the direction of the radiation of the whole device, directed is. To a big one To get luminosity, you need a big plate.

Aber in vielen Konstruktionen von Beleuchtungseinrichtungen, z. B. Laternen, Ampeln, Scheinwerfer, Theaterleuchten, usw. muss die Platte bestimmten Ausmaße haben, die durch die traditionellen Ausmaße dieser Konstruktionen bestimmt sind. Eine Vergrößerung dieser Ausmaße ist höchst unerwünscht.But in many constructions of lighting equipment, e.g. B. Lanterns, Traffic lights, headlights, theater lights, etc. must be the plate determined dimensions which are determined by the traditional proportions of these constructions are. An enlargement of this dimensions is the highest undesirable.

Daher liegt der Erfindung die Aufgabe zugrunde, eine Beleuchtungsvorrichtung oben genannter Gattung anzugeben, durch die mehr Leuchtdioden vorsehbar sind, ohne die konstruktiven Ausmaße (Durchmesser) zu vergrößern.Therefore The invention is based on the object, a lighting device Specify above genus specified by the more light emitting diodes providable are without increasing the constructive dimensions (diameter).

Diese Aufgabe wird durch eine Beleuchtungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind dem Unteranspruch zu entnehmen.These Task is by a lighting device with the features of claim 1. Advantageous embodiments of the invention are the subclaim refer to.

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels unter Bezug auf die einzige Figur der Zeichnung näher erläutert.following The invention is based on an embodiment with reference explained in more detail on the single figure of the drawing.

Wie aus der einzigen Figur zu ersehen ist, besitzt Beleuchtungsvorrichtung ein Gehäuse 1, das als Zylinder oder Kegelstumpf ausgebildet ist. Entlang der Achse des Gehäuses 1 ist einen Reflektor 2 platziert, der als ein Kegel oder als eine vielflächige Pyramide ausgeführt ist. Der Spitzenwinkel des Kegels ist in diesem Beispiel gleich 90°. Einige Leuchtdioden 3 sind auf der inneren Oberfläche des Gehäuses 1 so platziert, dass die Widerspiegelungen ihrer Strahlungen von dem Reflektor 2 entlang der Achse der Vorrichtung gerichtet sind. Weiter geht der Lichtstrahl durch die Ausgangsöffnung 4 der Vorrichtung, wie es in Beleuchtungseinrichtungen allgemein üblich ist.As can be seen from the single figure, lighting device has a housing 1 , which is designed as a cylinder or truncated cone. Along the axis of the housing 1 is a reflector 2 placed as a cone or as a polyhedral pyramid. The apex angle of the cone is equal to 90 ° in this example. Some LEDs 3 are on the inner surface of the case 1 placed so that the reflections of their radiations from the reflector 2 directed along the axis of the device. The light beam continues through the exit opening 4 the device, as is common in lighting equipment.

Beim einem ausgewählten Spitzenwinkel des Kegels mit einem Basisdurchmesser R wird die Basisfläche, die in der Regel dem Platzieren der Leuchtdioden dient, gleich πR2 sein, die Seitenfläche der Einrichtung, wo die Leuchtdioden 3 platziert sind, wird gleich 2πR2, dass heißt, zwei Mal größer. Entsprechend wird auch die Diodenzahl in der Vorrichtung zwei Mal größer.At a selected apex angle of the cone with a base diameter R, the base area, which typically serves to place the light emitting diodes, will be πR 2 , the side surface of the device where the light emitting diodes 3 are placed equal to 2πR 2 , that is, two times larger. Accordingly, the number of diodes in the device becomes twice as large.

Die vorgeschlagene Vorrichtung erlaubt es, im Falle von monochromen Leuchtdioden, z. B. roten, gelben, grünen usw. eine optische Farbenmischung zu bekommen. In dem gemeinsamen Lichtstrahl werden nach der Spiegelung von dem Kegel alle Farben vermischt. Dadurch kann man mit roten, gelben und grünen Lichtdioden das quasiweiße Licht erhalten.The proposed device allows, in the case of monochrome Light emitting diodes, z. B. red, yellow, green, etc., an optical color mixture to get. In the common light beam are after the reflection from the cone all the colors are mixed. This can be done with red, yellow and green Light diodes the quasi-white Get light.
