Es ist Aufgabe der vorliegenden Erfindung, eine Deckeneinbauleuchte anzugeben, die eine deutlich geringere Höhe als die bekannten Leuchten aufweist und hinsichtlich ihrer Form mehr Gestaltungsmöglichkeiten bietet.It Object of the present invention, a recessed ceiling light indicate that has a much lower height than the known lights and offers more design options in terms of their form.
Diese Aufgabe wird durch eine Deckeneinbauleuchte, welche die Merkmale des Anspruchs 1 aufweist, gelöst.These Task is by a recessed ceiling light, which features of claim 1, solved.
Die
erfindungemäße Deckenleuchte
hat mit der bekannten Leuchte nach
Für den Fall, dass der größte Abstand zwischen dem Reflektor und dem Diffusor größer als die Höhe der Lichteintrittsfläche ist, beträgt vorzugsweise das Verhältnis der Breite einer Lichtkammer zu diesem größten Abstand mindestens 4:1. Besonders bevorzugt liegt das Verhältnis der Breite einer Lichtkammer zur Höhe der Lichteintrittsfläche bzw. zum größten Abstand zwischen dem Reflektor und dem Diffusor zwischen 4:1 und 5:1.In the case, that the biggest distance between the reflector and the diffuser is greater than the height of the light entry surface, is preferably the ratio the width of a light chamber at this maximum distance at least 4: 1. Particularly preferred is the ratio of the width of a light chamber to the height the light entry surface or the greatest distance between the reflector and the diffuser between 4: 1 and 5: 1.

Zum Erzielen einer gleichmäßigen Leuchtdichte über den Reflektorquerschnitt können mehrere zusätzliche Mittel an der Leuchte vorgesehen sein. Vorzugsweise werden z.B. die Lichteintrittsflächen für die Lichtkammer bzw. Lichtkammern ebenfalls durch Diffusoren gebildet.To the Achieving a uniform luminance over the Reflector cross section can several additional ones Means be provided on the lamp. Preferably, e.g. the light entry surfaces for the light chamber or light chambers also formed by diffusers.
Das Lichtverteiler-Element kann z.B. ein aus Seitenreflektoren und Querlamellen bestehendes Raster angeordnet sein. Auch andere optische Elemente wären denkbar, die ein interessanteres Aussehen der gesamten Leuchte bewirken, beispielsweise ein teillichtdurchlässiges Lochblech oder dergleichen.The Light distribution element may e.g. one made of side reflectors and cross blades existing grid may be arranged. Also other optical elements would be conceivable which cause a more interesting appearance of the entire luminaire, For example, a teillichtdurchlässiges perforated plate or the like.
Weiterbildungen der Leuchte können auch darin bestehen, daß der seitlich von der Lampe angeordnete Reflektor selbst teillichtdurchlässig ist. Es besteht dann die Möglichkeit, hinter diesem teillichtdurchlässigen Reflektor weitere Lichtquellen anzuordnen, die zum Erzielen besonderer Beleuchtungseffekte verwendet werden können.further developments the lamp can also consist in that the laterally arranged by the lamp reflector itself is partially transparent. There is then the possibility behind this teillichtdurchlässigen Reflector to arrange further light sources, which is to achieve special Lighting effects can be used.
Ist der Reflektor teillichtdurchlässig, so kann eine andere Weiterbildung auch darin bestehen, hinter dem Reflektor einen weiteren Reflektor anzuordnen, so daß hinter den Lichtkammern jeweils eine weitere Lichtkammer gebildet wird. Es besteht dann die Möglichkeit, innerhalb dieser weiteren Lichtkammern zusätzliche Lichtquellen anzubringen, die beispielsweise in ihrer Farbe und Helligkeit steuerbar sein können.is the reflector is partially transparent, so can another training also be behind the Reflector to arrange another reflector, so that behind the light chambers each have a further light chamber is formed. There is then the possibility to install additional light sources within these further light chambers, which can be controlled, for example, in their color and brightness can.
Hierbei kann es sich beispielsweise um steuerbare lichtemittierende Dioden (LED's) handeln. Dadurch können nochmals eine Vielzahl unterschiedlicher Beleuchtungseffekte erzielt werden.in this connection For example, these may be controllable light-emitting diodes (LED's) act. Thereby can again achieved a variety of different lighting effects become.
Schließlich kann zum Erzielen eines weiteren neuen Beleuchtungseffekts auch vorgesehen sein, daß innerhalb der Lichteintrittsflächen optische Elemente angeordnet sind, die eine farbliche Veränderung des auf den Reflektor gewordenen Lichts bewirken, so daß der die Lampe umgebende Bereich in einer etwas anderen Farbe erscheint.Finally, can be provided to achieve a further new lighting effect, that within the light entry surfaces optical elements are arranged, which is a color change effect of the light that has become the reflector, so that the Lamp surrounding area appears in a slightly different color.
Die erfindungsgemäße Leuchte kann dabei in mehreren verschiedenen Leuchtenarten Verwendung finden.The Lamp according to the invention can be used in several different types of luminaires.
Im folgenden soll die Erfindung anhand der beiliegenden Zeichnung näher erläutert werden. Es zeigen:in the Following, the invention will be explained in more detail with reference to the accompanying drawings. Show it:
