Gehäuselose Rettungszeichenleuchte mit LEDsHousingless escape sign luminaire with LEDs

Die Erfindung bezieht sich auf eine Leuchte einfachster Bauart zur Beleuchtung von Rettungszeichen in Sicherheitsbeleuchtungsanlagen. Rettungszeichenleuchten sind bisher immer mit Glühlampen oder Leuchtstofflampen bestückt. Aus Veröffentlichungen sind jedoch auch Leuchten bekannt, die als Leuchtmittel Leuchtdioden, im Folgenden LEDs genannt, verwenden (z. B. Offenlegungsschriften DE 3715943, DE 4341015; Gebrauchsmuster G 9105201.7). Diese Konstruktionen sind vorwiegend dadurch gekennzeichnet, daß Licht in der Weise optisch in eine Lichtleiterplatte eingekoppelt wird, daß LEDs in Bohrungen der Lichtleiterplatten eingesteckt sind. Dies hat folgende Nachteile: Sobald die LEDs auf einer Platine befestigt sind, muß der Mittenabstand der Bohrungen und der der LEDs paßgenau sein, d.h. es ist eine exakteste Fertigung mit dementsprechendeil Kosten notwendig. Optiken wie Reflektoren oder Streulinsen können nicht eingesetzt werden. Diese Konstruktionen erlauben auch keinen einfachen Wechsel der LEDs, weil diese verlötet sind.The invention relates to a lamp of the simplest design for illuminating escape signs in safety lighting systems. Escape sign lamps have always been equipped with incandescent lamps or fluorescent lamps. However, lamps are also known from publications that use light-emitting diodes, hereinafter referred to as LEDs, as light sources (e.g. published patent applications DE 3715943, DE 4341015; utility model G 9105201.7). These designs are mainly characterized by the fact that light is optically coupled into a light guide plate by inserting LEDs into holes in the light guide plates. This has the following disadvantages: As soon as the LEDs are attached to a circuit board, the center distance between the holes and that of the LEDs must be a precise fit, i.e. extremely precise manufacturing is necessary, with corresponding costs. Optics such as reflectors or scattering lenses cannot be used. These designs also do not allow for easy replacement of the LEDs because they are soldered.

Die vorliegende Erfindung beinhaltet die Idee, die bekannten Vorteile von Leuchtdioden mit einer besonders robusten und einfachen Konstruktion zu kombinieren, so daß Vandalensicherheit und damit höchste Funktionssicherheit einen Sicherheitszugewinn sowie geringe Fertigungskosten ergeben. Die Beleuchtung der Lichtleiterplatte (1) durch LEDs (2) ist dahingehend ausgeführt, daß die Rückseite der Lichtleiterplatte mattiert ist und daß durch Hinterlegen einer weißen Folie (3) das Reflexionsvermögen weiter erhöht wird. Die Lichteinstrahlung erfolgt von einer, bei besonders großen Leuchten von zwei Längsseiten der Lichtleiterplatte her mittels auf der Schmalkante der Längsseiten - im Gegensatz zu herkömmlichen Lösungen aufgesetzte LEDs. Die LEDs sind mit aufgesteckten Reflektoren (4) und Streulinsen (5) versehen, um eine hinreichend gleichmäßige Ausleuchtung der Platte zu erzielen. Wahlweise kann ein zusätzliches Streufeld unterhalb der LEDs in die Lichtleiterplatte eingearbeitet sein. Die LEDs sind ferner in Steckfassungen (6) eingesetzt, welche sie analog zu anderen Leuchtmitteln handhabbar machen. Die Steckfassungen dienen ferner dazu, eine einheitliche Höhe der LEDs zu erreichen. Die Steckfassungen sowie evtl. Schutzdioden (7) und strombegrenzende Bauteile wie Widerstände (8) oder Stromregler sind auf einer streifenförmigen geätzten Leuchtdioden-Trägerplatine (9) aufgelötet. Die Stromzufuhr zur Platine erfolgt über Kupferstifte (10), deren Enden in auf die Plattenschmalseite aufgeklebte Schraubklemmen (11) fuhren und gleichzeitig zur Befestigung und Höhenjustierung der Platine dienen.The present invention contains the idea of combining the known advantages of light-emitting diodes with a particularly robust and simple construction, so that vandal resistance and thus the highest level of functional reliability result in increased safety and low production costs. The illumination of the light guide plate (1) by LEDs (2) is designed in such a way that the back of the light guide plate is matte and that the reflectivity is further increased by placing a white film (3) behind it. The light is emitted from one, or in the case of particularly large lights from two long sides of the light guide plate by means of LEDs attached to the narrow edge of the long sides - in contrast to conventional solutions. The LEDs are provided with attached reflectors (4) and scattering lenses (5) in order to achieve sufficiently uniform illumination of the plate. Optionally, an additional scattering field can be incorporated into the light guide plate below the LEDs. The LEDs are also inserted in plug-in sockets (6), which make them easy to handle in the same way as other lighting devices. The plug-in sockets also serve to achieve a uniform height for the LEDs. The plug-in sockets and any protective diodes (7) and current-limiting components such as resistors (8) or current regulators are soldered onto a strip-shaped, etched LED carrier board (9). The power supply to the board is via copper pins (10), the ends of which lead into screw terminals (11) glued to the narrow side of the board and are also used to secure and adjust the height of the board.

Die LEDs sind in mindestens zwei Gruppen geschaltet, um Redundanz und damit eine Restfunktion der Leuchte bei Ausfall einer Gruppe zu erreichen. Beidseitig der Platine weist die Lichtleiterplatte Stützpfeiler aus Plattenmaterial auf, die zusammen mit einem metallischen U-Profil (12) oder einer Führungsplatte (13) mit Doppel-U-Profil eine mechanisch stabile Kammer bilden. Bei größeren Leuchten sind mehr als 2 Stützpfeiler und auch mehr als eine Platine einsetzbar.The LEDs are connected in at least two groups to achieve redundancy and thus a residual function of the light if one group fails. On both sides of the circuit board, the light guide plate has support pillars made of plate material, which together with a metallic U-profile (12) or a guide plate (13) with a double U-profile form a mechanically stable chamber. For larger lights, more than 2 support pillars and also more than one circuit board can be used.

Ein Rettungszeichen der Größe 300 mm &khgr; 140 mm ist mit 6 Hochleistungsleuchtdioden (je LED — 2 cd Lichtstärke) mit einer elektrischen Gesamtleistung von max. I W hinreichend ausgeleuchtet. An emergency sign measuring 300 mm x 140 mm is adequately illuminated with 6 high-performance light-emitting diodes (each LED - 2 cd luminous intensity) with a total electrical output of max. I W.

Bei Verwendung eines einfachen U-Proflles (12) wird die rückseitige weiße Folie durch Randverklebung befestigt. Die offenen Lichtleiterplattenschmalseiten werden dann mit Spiegelfolie oder Lack abgedeckt.When using a simple U-profile (12), the white film on the back is attached by edge bonding. The open narrow sides of the light guide plate are then covered with mirror film or paint.

Zwei Bohrungen (14) im oberen Teil der Lichtleiterplatte nehmen die Befestigungsschrauben auf, die durch das Aufsetzen des U-Profiles auf der Vorderseite verdeckt werden. Im Schraubendurchtrittsbereich weist das U-Profil auf der Rückseite nach unten offene Schlitze auf. Bei Verwendung der Führungsplatte (13), die die Lichtleiterplatte (1) klammerförmig umgreift, erfolgt die Befestigung der Leuchte über die mit Schrauben (16) montierte Führungsplatte. Die dann eingeschobene Lichtleiterplatte wird, wie beim U-Profil auch, über zwei Schrauben (15), die in Gewindebohrungen der Stützpfeiler eingedreht sind, mit dem Metallteil verbunden. Die eigentlichen Rettungszeichen sind durch Farbe oder Folie auf der Frontseite der Lichtleiterplatte aufgebracht.Two holes (14) in the upper part of the light guide plate accommodate the fastening screws, which are covered by placing the U-profile on the front. In the area where the screws pass through, the U-profile has slots on the back that are open downwards. When using the guide plate (13), which grips the light guide plate (1) like a clamp, the light is fastened using the guide plate mounted with screws (16). The light guide plate that is then inserted is connected to the metal part using two screws (15), as with the U-profile, which are screwed into threaded holes in the support pillars. The actual escape signs are applied using paint or foil on the front of the light guide plate.
