Abstract
Description
Die Erfindung beinhaltet eine Funktionseinheit aus mehreren Leuchtdioden und zuge ordneten Lichtleitern dergestalt, daß die Lichtleiter mind. von 2 Leuchtdioden angestrahlt werden und Oberflächenveränderungen an der Längsseite zu einer Abgabe von Licht zwecks Markierung durch Striche, Linien, Punkten, Symbolen u. a. erfolgt. Die zumindest doppelte Einstrahlung in den Lichtleiter kompensiert die Lichtverluste, so daß auf länge ren Abmessungen ein gleichmäßiges Markierungslicht erreicht wird.The invention includes a functional unit consisting of several light emitting diodes and arranged light guides in such a way that the light guides are illuminated by at least 2 light emitting diodes and surface changes on the long side to give off light for the purpose of marking with lines, lines, dots, symbols and the like. a. he follows. At least Double irradiation in the light guide compensates for the loss of light, so that length a uniform marker light is achieved.
Anwendungen sind vorzugsweise im Kraftfahrzeug, darüber hinaus aber auch in abge dunkelten Räumen, wie Flugzeugen, Schutzräumen usw.Applications are preferably in the motor vehicle, but also in abge dark rooms, such as airplanes, shelters, etc.
Der Vorteil der Erfindung liegt darin, daß der Stromverbrauch durch Leuchtdioden äu ßerst gering ist und somit mit Batterien, Notaggregaten u. a. entsprechende Beleuch tungszustände über lange Zeiträume erhalten bleiben oder gesteuert werden können, wobei Sensoren oder Meßinstrumente (Temperatur, Feuchte u. a.) die Steuerungsfunkti on übernehmen und durch Verwendung von Mehrfarben-LED auch unterschiedliche Zustände angezeigt werden können, z. B. Verbot, Erlaubnis, Gefahr, oder ähnliches. The advantage of the invention is that the power consumption by light emitting diodes is extremely low and thus with batteries, emergency units and. a. appropriate lighting conditions can be maintained or controlled over long periods of time, where sensors or measuring instruments (temperature, humidity, etc.) control functions on, and by using multi-color LEDs also different ones States can be displayed, e.g. B. Prohibition, permission, danger, or the like.
Bekannt sind Systeme, bei denen an eine zentrale Lichtquelle (Glühlampe) Systeme von Lichtleitern angekoppelt sind, wobei über Lichtverteiler eine Lichtzuführung zu den ein zelnen Bedarfsstellen erreicht wird.Systems are known in which systems from a central light source (incandescent lamp) Optical fibers are coupled, with a light supply to the one via light distributors individual needs is reached.
Mit diesem Prinzip ist im Wesentlichen nur eine punktmäßige Ausleuchtung möglich.With this principle, only spot illumination is essentially possible.
Darüber hinaus sind auch Lichtleiter bekannt, die reine Signalfunktionen ausüben und von Leuchtdioden angestrahlte Lichtleiter, die über Prismen oder Spiegelungen Lichtver teilungen oder Umlenkungen vornehmen.In addition, light guides are also known that perform pure signal functions and light guides illuminated by light-emitting diodes, which light pr Make divisions or redirections.
Bei der Erfindung handelt es sich gem. Fig. 1 um Lichtleiter (1) in größeren Dimensio nen, die von zweien oder mehreren LEDs (2), bzw. Kontra-LEDs (2a), die in LED-Fas sungen (3) eingesetzt werden können, stirnseitig so angestrahlt werden, daß durch Strukturveränderungen auf der Längsfläche des Lichtleiters (1) Licht abgegeben wird, das durch die mehrfache Einstrahlung homogen gestaltet wird. Es kann sich hierbei um Lichtleiter (1) aus Glasfaser oder Kunststoff handeln, die in Meterware mit rundem, qua dratischem oder rechteckigem Querschnitt hergestellt werden und die durch Verände rungen der Oberfläche an bestimmten Sichtflächen entgegen dem normalen Prinzip, das eingebrachte Licht nicht am Ende des Lichtleiters abstrahlen, sondern auf der Strecke durch Lichtaustritte (4a-4e) gezielt abgeben und damit eingebettet in Lichtleiterauf nahme (7), Nuten oder andere Vertiefungen eines Lichtleiterträgers (6), aus Kunststoff, Metall oder Ähnlichem deutliche Lichtmarkierungen in möglicherweise umschaltbaren Farben abgibt. Dieser Lichtleiterträger (6), ist vorzugsweise flächenförmig, kann aber auch in einer Körperform als Trägerkörper (6a) gem. Fig. 5, wie Kugeln, Walzen oder Ähnlichem bestehen, wobei dann durch Rotieren besondere Lichteffekte erzielt werden können. The invention is gem. Fig. 1 to light guide ( 1 ) in larger dimensions, the face of two or more LEDs ( 2 ), or contra-LEDs ( 2 a), which can be used in LED-Fas solutions ( 3 ), are illuminated at the front that due to structural changes on the longitudinal surface of the light guide ( 1 ) light is emitted which is made homogeneous by the multiple irradiation. It can be optical fibers ( 1 ) made of glass fiber or plastic, which are manufactured by the meter with a round, square or rectangular cross-section and which, due to changes in the surface on certain visible surfaces, contrary to the normal principle, the light introduced does not end at the end Radiate light guide, but deliver it on the route through light exits ( 4 a - 4 e) and thus embedded in light guide receptacle ( 7 ), grooves or other recesses of a light guide carrier ( 6 ), made of plastic, metal or similar clear light markings in possibly switchable colors delivers. This optical fiber support (6), is preferably flat-shaped, but may also be in the form of a body as the carrier body (6 a) gem. Fig. 5, such as balls, rollers or the like, in which case special lighting effects can then be achieved by rotating.
Gem. Fig. 2a, b und c können die Lichtleiter (1) mit Lichtaustritten (4) flexibel oder in unterschiedlichen starren Formen gestaltet werden.Gem. Fig. 2a, b and c, the light conductor (1) are designed with light outlets (4) is flexible or rigid in different forms.
Gem. Fig. 3 ist es möglich, durch Prismen/Spiegel (8) das Licht der LED (2) auch winkelmäßig versetzt einzustrahlen, oder aber auch durch Doppelprisma (8a) in zwei Richtungen abzugeben. Durch diesen Effekt können geschlossene Lichtleiterkreise (14) gern. Fig. 4 gebildet werden.According to FIG. 3, it is possible to irradiate the light of the LED ( 2 ) with an angular offset by prisms / mirrors ( 8 ), or to emit it in two directions by means of a double prism ( 8 a). Due to this effect, closed light guide circles ( 14 ) are welcome. Fig. 4 are formed.
In allen Ausführungen bleibt die Verbindungstechnik für die LED-Anschlüsse (5), evtl. auch unter Einbeziehung von Vorwiderständen, frei gestaltbar.In all versions, the connection technology for the LED connections ( 5 ) can be freely designed, possibly including series resistors.
Einzelne Lichtleiter (1) können gem. Fig. 6 als Lichtleiterstränge (16) über Vebin dungsstege (10) auch zu Lichtleitergittern (9) vereinigt werden, die durch Steuermecha nismen wahlweise in Funktion treten.Individual light guides ( 1 ) can acc. Fig. 6 as fiber optic strands ( 16 ) via Vebin extension webs ( 10 ) can also be combined to fiber optic grids ( 9 ), the mechanisms optionally come into play through control mechanisms.
Gem. Fig. 7 sind auch andere Lichtleitersysteme (11) realisierbar, bei denen ein Licht leiter (1) über Lichtleiterumlenkung (12) in einen anderen Lichtleiter (1) einstrahlt, oder dieses Licht über eine Lichtleiterweiche (13) in die Lichtleiterarme (15) gesplittet einge strahlt wird.Gem. Fig. 7, other optical fiber systems (11) can be realized in which an optical fiber (1) is irradiated via light guides deflection (12) in another optical fiber (1) or this light via a light guide switch (13) in the light guide arms (15 ) is radiated in split.
