Abstract

A color effect light or lamp with a three-dimensionally extending transparent lampshade on which luminous areas of various forms and colors are to be produced. A light mixing and reflecting body having an effective three-dimensionally shaped outside-surface is at least partially surrounded by the transparent lampshade. Differently colored illuminants whose brightness can be regulated separately are provided to illuminate the outside-surface of the light mixing and reflecting body, and spaced from one another. Preferably, each illuminant includes directing member for concentrating or focusing the light into a homogeneously coloured light beam, and is adjusted to cast its light beam in a direction to the effective outside-surface of the light mixing and reflecting body where differently colored light beams meet one another and are transformed by additional mixing into light of various colors. This light is reflected onto the inside of the transparent lampshade which transmits it to its outside producing the luminous areas of various forms and colors.

Description

Farbeffektleuchte Color effect lamp
Die Erfindung betrifft eine Farbeffektleuchte, die Licht aller Farben erzeugt. Das Prinzip der Lichterzeugung beruht auf dem an sich bekannten Prinzip der „additiven Farbmischung". Bei diesem Verfahren werden die 3 Grundfarben rot, grün und blau übereinander projiziert und ergeben je nach Intensität der einzelnen Farben alle Farben des Regenbogens einschließlich weiß.The invention relates to a color effect lamp that generates light of all colors. The principle of light generation is based on the principle of "additive color mixing", which is known per se. In this method, the three primary colors red, green and blue are projected one above the other and, depending on the intensity of the individual colors, result in all colors of the rainbow, including white.
Die vorliegende Erfindung befaßt sich mit der Nutzung dieses Prinzips zum Einsatz in einer Farbeffektleuchte.The present invention is concerned with the use of this principle for use in a color effect lamp.
Als Stand der Technik ist der Prospekt der Fa. Artemide, Via Bergamo, 18, I- 20010 Pregnana Milanese bekannt. Dieser Lampenprospekt beschreibt eine ganze Anzahl von Produkten, die farbige Leuchtmittel verwenden, wobei die additive Farbmischung, wie herkömmlich üblich, auf dem Lampenschirm erfolgt. Damit die gewünschten Farbeffekte entstehen können, muß der Lampenschirm eine funktionell vorbestimmte Form aufweisen, d. h. der Lampenschirm bzw. Flä- chenabschnitte des Lampenschirmes, auf denen die Farbeffekte durch Lichtmischung entstehen sollen, müssen zu den Lichtstrahlen der Farblichtquellen in einer vorbestimmten räumlichen Lage angeordnet sein. Diese vorbestimmte Lage der Lichtmischabschnitte kann durch eine vorbestimmte Form des Lampenschirmes erreicht werden. Damit ist jedoch der Nachteil verbunden, daß die Form des Lampenschirmes nicht mehr frei wählbar ist. Die Form eines Lampenschirmes wird jedoch wesentlich von ästhetischen Gesichtspunkten bestimmt. Ein unter ästhetischen Gesichtspunkten gestalteter Lampenschirm weist jedoch in der Regel nicht die für die Farbeffekterzeugung erforderliche Geometrie auf. Da die äußere, die sichtbare Form des Lampenschirmes in der Regel Vorrang vor der Funktionalität, d. h. zur Erzeugung von Farbeffekten hat, können mit solchen Lampenanordnungen nur Farbeffekte mit geringer Variabilität erzielt werden.The brochure from Artemide, Via Bergamo, 18, I-20010 Pregnana Milanese is known as prior art. This lamp brochure describes a whole number of products that use colored lamps, the additive color mixing, as is customary, takes place on the lampshade. So that the desired color effects can arise, the lampshade must have a functionally predetermined shape, ie the lampshade or surface sections of the lampshade on which the color effects are to be created by light mixing must be arranged in a predetermined spatial position with respect to the light beams of the color light sources. This predetermined position of the light mixing sections can be achieved by a predetermined shape of the lampshade. However, this has the disadvantage that the shape of the lampshade can no longer be freely selected. However, the shape of a lampshade is largely determined by aesthetic considerations. However, a lampshade designed from an aesthetic point of view generally does not have the geometry required for producing the color effect. Because the outer, the visible shape of the lampshade usually takes precedence before the functionality, ie for the generation of color effects, only such color effects with little variability can be achieved with such lamp arrangements.
Es ist daher die Aufgabe der Erfindung, eine Farbeffektleuchte bereitzustellen, mit der sehr variable Farbeffekte erzeugt werden können, ohne daß dazu die äußere, ästhetisch vorbestimmte Form des Lampenschirmes abgewandelt werden muß.It is therefore the object of the invention to provide a color effect lamp with which very variable color effects can be produced without having to modify the outer, aesthetically predetermined shape of the lampshade.
Die Erfindung wird durch die Kombination der Merkmale nach Patentanspruch 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.The invention is achieved by the combination of the features according to claim 1. Advantageous further developments are the subject of the subclaims.
Nach Anspruch 1 weist eine Leuchte mehrere, verschiedenfarbige Leuchtmittel und einen Lampenschirm auf. Innerhalb des Lampenschirmes ist ein Lichtmisch- und Reflexionskorper angeordnet, der von den Leuchtmitteln angestrahlt wird.According to claim 1, a lamp has several differently colored lamps and a lampshade. A light mixing and reflection body is arranged within the lampshade and is illuminated by the lamps.
Der Lichtmisch- und Reflexionskorper ist z. B. ein Kegel aus optisch klarem Kunststoff. Die Oberfläche ist mattiert. Der Kegel kann auch hohl sein. Wenn verschiedenfarbiges Licht aus verschiedenen Richtungen auf die Mantelfläche des Kegels auftrifft, kommt es auf der Mantelfläche zu einer additiven Farbmischung. Ein Teil des Lichtes kann auch in den Kegel eindringen und tritt auf der gegenüber liegenden Seite wieder aus. Auf dieser Seite mischt sich dann das auftreffende Licht mit dem austretenden Licht, was ebenfalls zu Farbeffekten führt.The light mixing and reflection body is e.g. B. a cone made of optically clear plastic. The surface is matted. The cone can also be hollow. When light of different colors hits the surface of the cone from different directions, an additive color mixture occurs on the surface. Part of the light can also penetrate the cone and exit on the opposite side. On this side, the incident light mixes with the emerging light, which also leads to color effects.
Die Form des Lichtmisch- und Reflexionskörpers kann beliebig sein und beeinflußt die Form und die Farbeffekte auf dem Lampenschirm. Es kommt lediglich darauf an, daß auf der Oberfläche des Lichtmisch- und Reflexionskörpers eine additive Farbmischung erzeugt und dieses Mischlicht auf den Lampenschirm abgestrahlt wird. Zur Erzeugung der verschiedensten Lichteffekte ist die Helligkeit der Leuchtmittel regelbar, wobei sogar weißes Licht erzeugt werden kann.The shape of the light mixing and reflection body can be arbitrary and influences the shape and the color effects on the lampshade. The only thing that matters is that an additive color mixture is generated on the surface of the light mixing and reflection body and this mixed light is emitted onto the lampshade. The brightness of the illuminants can be regulated to produce a wide variety of lighting effects, and even white light can be generated.
Nach Anspruch 2 ist der Lichtmisch- und Reflexionskorper lichtundurchlässig, z. B. mattweiß. Die additive Lichtmischung erfolgt nur auf dem Flächenabschnitt des Lichtmisch- und Reflexionskörpers, der von den jeweiligen Leuchtmitteln direkt bestrahlt wird. Das Mischlicht wird von diesem Flächenabschnitt auf die Innenfläche des Lampenschirms abgestrahlt und erscheint dort als farbiger Leuchtfleck. Wenn die Farbanteile gleichverteilt sind, erscheint ein weißer Leuchtfleck.According to claim 2, the Lichtmisch- and reflection body opaque, for. B. matt white. The additive light mixing takes place only on the surface section of the light mixing and reflection body, which is directly irradiated by the respective illuminants. The mixed light is emitted from this surface section onto the inner surface of the lampshade and appears there as a colored light spot. If the color components are evenly distributed, a white light spot appears.
Nach Anspruch 3 ist der Lichtmisch- und Reflexionskorper lichtdurchlässig und hat eine Oberfläche, die zur additiven Lichtmischung geeignet ist. Das kann z. B. ein Glaskörper mit einer mattierten Oberfläche sein. Auf dieser mattierten Ober- fläche wird ein Teil des auftreffenden Lichtes gemischt und als Mischlicht auf die Innenseite des Lampenschirmes gestrahlt. Der andere Teil des von den farbigen Leuchtmitteln abgestrahlten Lichtes durchdringt den Glaskörper und trifft auf der gegenüberliegenden Seite des Glaskörpers von innen auf die mattierte Oberfläche, wo ebenfalls eine additive Farbmischung auftritt. Dieses Mischlicht wird auch auf die Innenseite des Lampenschirmes gestrahlt.According to claim 3, the light mixing and reflection body is translucent and has a surface that is suitable for additive light mixing. That can e.g. B. a glass body with a matt surface. Part of the incident light is mixed on this matted surface and emitted as mixed light on the inside of the lampshade. The other part of the light emitted by the colored light sources penetrates the glass body and hits the matt surface from the inside on the opposite side of the glass body, where an additive color mixture also occurs. This mixed light is also emitted on the inside of the lampshade.
Der Fachmann kann durch die Gestaltung der Form und der Oberflächen des Farbmisch- und Reflektionskörpers, speziell seiner Lichtdurchlässigkeit und Oberflächenstruktur die verschiedensten Lichtmisch- und Farbeffekte erzeugen.The person skilled in the art can produce a wide variety of light mixing and color effects through the design of the shape and the surfaces of the color mixing and reflection body, especially its translucency and surface structure.
Nach Anspruch 4 ist der Lichtmisch- und Reflexionskorper als Kegel und der Lampenschirm als Zylinder ausgebildet ist. Der Kegel steht auf der Spitze und ist in dem Zylinder konzentrisch angeordnet. Die Leuchtmitteln sind um die Kegelspitze herum kreisförmig angeordnet und strahlen auf den Kegelmantel, wo das Licht additiv gemischt und auf die Innenseite des zyiinderförmigen Lampenschirmes abgestrahlt wird.According to claim 4, the light mixing and reflection body is designed as a cone and the lampshade as a cylinder. The cone is on the tip and is arranged concentrically in the cylinder. The lamps are arranged in a circle around the cone tip and shine on the cone shell, where the light is mixed additively and emitted onto the inside of the cylindrical lampshade.
Nach Anspruch 5 ist der Kegel hohl und der Kegelmantel aus einer weißen, durchscheinenden Kunststofffolie gefertigt. Diese Ausführungsform eignet sich besonders für eine kostengünstige Produktion bei großen Stückzahlen.According to claim 5, the cone is hollow and the cone jacket made of a white, translucent plastic film. This embodiment is particularly suitable for cost-effective production in large quantities.
Nach Anspruch 6 ist der Lichtmisch- und Reflexionskorper auswechselbar. Diese Maßnahme ist ebenfalls für eine kostengünstige Produktion bei großen Stückzahlen geeignet. Die Erfindung wird nunmehr an Hand eines Beispiels in Verbindung mit Zeichnungen näher erläutert.According to claim 6, the light mixing and reflection body is interchangeable. This measure is also suitable for cost-effective production in large quantities. The invention will now be explained in more detail using an example in conjunction with drawings.
Fig. 1 zeigt eine Prinzipdarstellung der Erfindung in der Seitenansicht. Fig. 2 zeigt die Prinzipdarstellung von Fig. 1 in der Draufsicht.Fig. 1 shows a schematic representation of the invention in side view. Fig. 2 shows the schematic diagram of Fig. 1 in plan view.
Die Fig. 1 zeigt eine Farbeffektleuchte mit Leuchtmitteln 1 , 2 und 3, die sternförmig und schwenkbar angeordnete sind, um ihre Lichtkegel justieren zu können. Die Leuchtmittel 1 , 2, 3 sind am unteren Endabschnitt eines zylinderförmi- gen Lampenschirmes 4 angeordnet und strahlen schräg nach oben auf einen kegelförmigen Lichtmisch- und Reflexionskorper 5. Die Leuchtmittel können wie bei dieser Ausführung jeweils einen Farbfilter V, 2' und 3' oder eingefärbte Glaskolben aufweisen. Die von den Leuchtmitteln 1 und 2 ausgehenden Lichtstrahlen treffen sich auf der Oberfläche des kegelförmigen Lichtmisch- und Reflexions- körpers 5 im Punkt 6. Das dort entstehende Mischlicht wird abgestrahlt und trifft auf die Innenseite des zyiinderförmigen Lampenschirmes 4 im Punkt 7, der von außen als farbiger Leuchtfleck erscheint.Fig. 1 shows a color effect lamp with illuminants 1, 2 and 3, which are arranged in a star shape and pivoted so that their light cones can be adjusted. The illuminants 1, 2, 3 are arranged on the lower end section of a cylindrical lampshade 4 and shine obliquely upwards onto a conical light mixing and reflection body 5. The illuminants can each have a color filter V, 2 'and 3' or have colored glass flasks. The light rays emanating from the illuminants 1 and 2 meet on the surface of the conical light-mixing and reflection body 5 at point 6. The mixed light which is produced there is emitted and strikes the inside of the cylindrical lampshade 4 at point 7, which from the outside as colored light spot appears.
Es ist für den Fachmann klar, daß das Ausführungsbeispiel nur eine von vielen möglichen Ausführungsformen zeigt, wobei jedoch die technische Lehre in Verbindung mit dem verbleibenden Teil der Beschreibung und den Ansprüchen so vollständig offenbart wurde, daß jede Ausführungsform einer Farbeffektleuche in den Schutzbereich der nachfolgenden Patentansprüche fällt, wenn die technische Lehre des separaten Farbmisch- und Reflexionskörpers nach Patentan- spruch 1 angewendet wird. It will be apparent to those skilled in the art that the embodiment shows only one of many possible embodiments, but the technical teaching in connection with the remaining part of the description and the claims has been disclosed so completely that each embodiment of a color effect tube falls within the scope of the following claims falls when the technical teaching of the separate color mixing and reflection body according to claim 1 is applied.
