Abstract
Description
Die Erfindung betrifft eine Farbeffektleuchte gemäß dem Oberbegriff des Anspruchs 1. Diese Leuchte erzeugt
Licht aller Farben.The invention relates to a color effect lamp according to the preamble of
Das Prinzip der Erzeugung von Licht aller Farben 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. Leuchten zur Erzeugung beliebig farbigen Lichts sind bespielsweise aus GB - A - 1 007 257 und aus US - A - 3 949 350 bekannt und auch im Handel erhältlich. Im Stand der Technik werden farbige Leuchtmittel verwendet, wobei die additive Farbmischung auf dem Lampenschirm erfolgt. Damit die gewünschten Farbeffekte entstehen können, muß der Lampenschirm eine funktionell vorbestimmte Form aufweisen, d. h. der Lampenschirm bzw. Flächenabschnitte 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 principle of producing light of all colors is based on the known Principle of "additive color mixing". In this process, the 3 primary colors red, green and blue projected on top of each other and give depending on Intensity of each color including all the colors of the rainbow White. Lights for generating any colored light are recordable off GB-A-1 007 257 and US-A-3 949 350 are known and are also commercially available available. In the prior art colored lamps are used, wherein additive color mixing takes place on the lampshade. Thus the desired Color effects may arise, the lampshade must be a functionally predetermined Have shape, d. H. the lampshade or surface sections of Lampshade on which the color effects are created by light mixing should be to the light rays of the color light sources in a predetermined be arranged in a spatial location. 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 no longer freely selectable. The shape of a lampshade, however, is essentially determined by aesthetic considerations. One under aesthetic However, designed lampshade usually does not have the geometry required for color effect generation. Because the outer, the visible shape of the lampshade usually takes precedence over the functionality, d. H. to produce color effects, can with such lamp assemblies only color effects with low variability can be achieved.
Eine Farbeffektleuchte der anfangs genannten Art ist aus US - A - 5 749 646 bekannt. Zur Erzeugung unterschiedlicher Farbeffekte nebeneinander weist sie mehrere Gruppen verschiedenfarbiger Leuchtmittel auf, deren Helligkeit jeweils getrennt zu regeln ist. Wegen des hohen Aufwands eignet sich die bekannte Leuchte nicht zur preiswerten Massenfertigung. Außerdem ist Form und Zuordnung der Farbeffekte nebeneinander bei der bekannten Leuchte durch die geometrische Ausgestaltung des Lampenschirms unveränderlich bestimmt.A color effect lamp of the type mentioned initially is known from US Pat. No. 5,749,646 known. To create different color effects side by side, it has several groups of different colored bulbs, the brightness of each is to be regulated separately. Because of the high cost, the well-known Luminaire not for low-cost mass production. In addition, form and assignment the color effects side by side in the known lamp by the geometric Design of the lampshade invariably determined.
Die Erfindung befaßt sich mit der Nutzung des Prinzips der Lichtmischung mittels
einer Gruppe verschiedenfarbiger Leuchtmittel zum Einsatz in einer Farbeffektleuchte.
Es ist 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. Diese Aufgabe wird erfindungsgemäß durch die Kombination der im
beigefügten Patentanspruch 1 angegebenen Merkmale gelöst. Die abhängigen
Ansprüche betreffen besonders vorteilhafte Ausführungsarten der Erfindung.The invention is concerned with the use of the principle of light mixing by means
a group of different colored bulbs for use in a color effect light.
It is the object of the invention to provide a color effect lamp,
can be generated with the very variable color effects, without that the
outer, aesthetically predetermined shape of the lampshade are modified
got to. This object is achieved by the combination of the
attached
Die erfindungsgemäße Farbeffektleuchte weist mehrere, verschiedenfarbige Leuchtmittel, deren Helligkeit getrennt regelbar ist, und einen sich dreidimensional erstreckenden lichtdurchlässigen Lampenschirm auf. Innerhalb des Lampenschirms befindet sich ein Lichtmisch- und Reflexionskörper mit dreidimensional ausgebildeter Oberfläche, die von den von verschiedenen Seiten auf den Lichtmisch- und Reflexionskörper gerichteten verschiedenfarbigen Leuchtmitteln angestrahlt wird. Auf dem Lichtmisch- und Reflexionskörper mischt sich verschieden farbiges Licht additiv. Das additiv gemischte Licht wird dann auf die Innenfläche des Lampenschirms abgestrahlt und dort für den Betrachter als Farbeffekt sichtbar. Es ist nur eine Gruppe verschiedenfarbiger Leuchtmittel notwendig, um auf dem Lichtmisch- und Reflexionskörper unterschiedliche Farbeffekte nebeneinander zu erzeugen. Diese Farbeffekte ändern sich nach Form Größe und Zuordnung nach Regelung der Helligkeit der einzelnen Leuchtmittel.The color effect lamp according to the invention has several different colors Illuminants whose brightness can be regulated separately, and a three-dimensional extending translucent lampshade. Within the Lampshade is a Lichtmisch- and reflection body with three-dimensional trained surface, from the different sides on the Lichtmisch- and reflection body directed differently colored bulbs is illuminated. On the light mixing and reflection body mixes different colored light additive. The additive mixed light is then applied to the Inner surface of the lampshade emitted and there for the viewer as a color effect visible. There is only one group of different colored bulbs necessary, on the Lichtmisch- and reflection body different color effects to produce next to each other. These color effects change according to form Size and assignment after regulation of the brightness of the individual lamps.
Der Lichtmisch- und Reflexionskörper 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 Lichtmisch- and reflection body is z. B. a cone of optically clear Plastic. The surface is frosted. The cone can also be hollow. If different colored light from different directions on the lateral surface of the cone, it comes on the lateral surface to an additive color mixture. Part of the light can also penetrate into the cone and occurs the opposite side again. On this page mixes then the incident light with the exiting light, which also leads to color effects leads.
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 Lichtmisch- and reflection body can be arbitrary and influenced the shape and the color effects on the lampshade. It only comes on that on the surface of the light mixing and reflection body a additive color mixing produced and this mixed light emitted to the lampshade becomes. To generate a variety of lighting effects is the brightness the lamp controllable, whereby even white light can be generated.
Der Lichtmisch- und Reflexionskörper kann lichtundurchlässig, z. B. mattweiß sein. 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.The Lichtmisch- and reflection body can be opaque, z. Eg matt white his. 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 bulbs becomes. The mixed light is from this surface portion on the inner surface emitted the lampshade and appears there as a colored spot. If the color components are evenly distributed, a white spot appears.
Mit einem lichtdurchläsigen Lichtmisch- und Reflexionskörper, dessen Oberfläche zur additiven Lichtmischung geeignet ist, können besondere Farbeffekte erzeugt werden. Das kann z. B. ein Glaskörper mit einer mattierten Oberfläche sein. Auf dieser mattierten Oberfläche wird ein Teil des auftreffenden Lichtes gemischt und als Mischlicht auf die Innenseite des Lampenschirmes gestrahlt. With a translucent Lichtmisch- and reflection body whose surface is suitable for additive light mixing, special color effects can be generated become. This can z. As a glass body with a frosted surface his. On this frosted surface becomes a part of the incident light mixed and blasted as mixed light on the inside of the lampshade.
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.The other part of the light emitted by the colored lamps penetrates the vitreous body and meets on the opposite side of the vitreous body from the inside to the matted surface, where also an additive color mixture occurs. This mixed light is also on the inside of the lampshade blasted.
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 skilled person can by shaping the shape and surfaces of the Color mixing and reflection body, especially its translucency and Surface structure to produce a variety of light mixing and color effects.

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 zylinderförmigen Lampenschirmes abgestrahlt wird. Der Kegel kann hohl und der Kegelmantel aus einer weißen, durchscheinenden Kunststofffolie gefertigt sein. Diese Ausführungsform eignet sich besonders für eine kostengünstige Produktion bei großen Stückzahlen.A preferred embodiment of the invention is that the Lichtmisch- and Reflection body designed as a cone and the lampshade as a cylinder is. The cone stands on top and is concentric in the cylinder arranged. The bulbs are arranged in a circle around the cone tip and radiate on the cone sheath, where the light is additively mixed and on the inside of the cylindrical lampshade is radiated. The cone may be hollow and the cone coat of a white, translucent plastic film be made. This embodiment is particularly suitable for a cost-effective production in large quantities.
