Abstract
Description
Die Erfindung betrifft eine Leuchte, insbesondere Straßenleuchte mit einem Leuchtenkopf, in oder an der als Leuchtmittel LEDs auf einem Tragelement insbesondere auf einer Platine befestigt sind.The invention relates to a lamp, in particular street lamp with a lamp head, are mounted in or on the LEDs as a light source on a support member, in particular on a circuit board.
Es ist bekannt, den Leuchtenkopf einer Straßenleuchte mit LEDs als Leuchtmittel auszustatten. Je nach der gewünschten Größe und Breite der auszuleuchtenden Fläche werden die mit LEDs ausgerüsteten Unterlagen im Leuchtenkopf entsprechend angeordnet. Damit ist es erforderlich, für jeden Einsatzfall entsprechend konstruierte Leuchtenköpfe herzustellen. Auch ist eine spätere Veränderung der Strahlrichtung der LEDs nicht mehr möglich.It is known to equip the lamp head of a street lamp with LEDs as a light source. Depending on the desired size and width of the surface to be illuminated, the documents equipped with LEDs in the lamp head are arranged accordingly. This makes it necessary to produce appropriately designed lamp heads for each application. Also, a later change in the beam direction of the LEDs is no longer possible.
Aufgabe der Erfindung ist es, eine Leuchte der eingangs genannten Art so zu verbessern, dass jederzeit und insbesondere auch vor Ort die Leuchtrichtungen der LEDs leicht ohne größeren Arbeitsaufwand veränderbar und damit anpassbar und insbesondere justierbar ist, so dass gleich oder ähnlich gebaute Leuchten für die verschiedensten Anforderungen einsetzbar sind; und dies bei einfacher und preiswerter Konstruktion.The object of the invention is to improve a lamp of the type mentioned above so that at any time and especially on site, the light directions of the LEDs easily without major effort changeable and thus adaptable and in particular adjustable, so that the same or similar built lights for a variety Requirements can be used; and this with a simple and inexpensive construction.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Tragelement insbesondere die Platine mit ihren LEDs auf einer Unterlage durch Befestigungsmittel in ihrer Lage derart veränderbar gehalten sind, dass die LEDs jeweils eine Leuchtrichtung besitzen, bei der die zentrale Abstrahlsachse mit der Oberfläche der Unterlage einen von 90 Grad abweichenden Winkel bildet.This object is achieved in that the support element, in particular the board with its LEDs on a base by fastening means in their position are held so changeable that the LEDs each have a direction of light, wherein the central Abstrahlsachse with the surface of the pad one of 90 Degree deviating angle forms.
Hierbei können unterschiedliche Tragelemente mit in Anzahl und Art unterschiedlich besetzten LEDs auf derselben Unterlage eingesetzt werden, die auch leistenförmig sein kann.Here, different support elements can be used with differently occupied in number and type LEDs on the same base, which can also be strip-shaped.
Eine solche Leuchte ist für die verschiedensten Zwecke und damit sowohl für die Außen- als auch für die Innenbeleuchtung vorteilhaft einsetzbar. Mit einfachsten Mitteln und jederzeit können die Abstrahlrichtungen der LEDs in der Leuchte an die jeweiligen Gegebenheiten angepasst werden, so dass optimale Ausleuchtungen bei einfachster Herstellung und Handhabung erreichbar sind. Hierbei ist besonders vorteilhaft, wenn das Befestigungsmittel eine Verstelleinrichtung aufweist, durch die der Winkel und/oder die Richtung der LED-Abstrahlachsen verstellbar ist.Such a lamp is advantageously used for a variety of purposes and thus both for outdoor and for interior lighting. With the simplest means and at any time, the emission directions of the LEDs in the luminaire can be adapted to the respective conditions, so that optimal illumination with the simplest production and handling can be achieved. It is particularly advantageous if the fastening means comprises an adjusting device, by which the angle and / or the direction of the LED emission axes is adjustable.
Vorzugsweise wird vorgeschlagen, dass die Verstelleinrichtung mindestens ein Drehgelenk aufweist, durch das das Tragelement insbesondere die Platine gegenüber der Unterlage drehverstellbar ist. Hierbei kann die Drehachse des Drehgelenks parallel oder senkrecht zur Oberfläche der Unterlage angeordnet sein. Auch wird hierzu vorgeschlagen, dass das Drehgelenk ein Fest- oder Rastgesperre aufweist.Preferably, it is proposed that the adjusting device has at least one rotary joint, by means of which the carrier element, in particular the printed circuit board, is rotationally adjustable relative to the base. In this case, the axis of rotation of the rotary joint can be arranged parallel or perpendicular to the surface of the base. It is also proposed that the hinge has a fixed or locking mechanism.
Ein sicherer Halt bei hoher Flexibilität wird erreicht, wenn das Befestigungsmittel formschlüssig in oder an der Unterlage gehalten ist. Hierbei ist von Vorteil, wenn das Befestigungsmittel mit einem Vorsprung insbesondere einem Zapfen in der Unterlage eingesteckt ist. Dabei kann der Zapfen als Mehrkant in verschiedene Drehstellungen in eine entsprechend geformte Ausnehmung der Unterlage formschlüssig einsteckbar sein. Eine zusätzliche elektrische Anschlussfunktion wird hierbei erreicht, wenn der Zapfen ein elektrischer Stecker ist, der in der Unterlage Kontakte kontaktiert.A secure hold with high flexibility is achieved when the fastener is positively held in or on the pad. It is advantageous if the fastening means is inserted with a projection, in particular a pin in the pad. In this case, the pin can be inserted in a form-fitting manner as a polygon in different rotational positions in a correspondingly shaped recess of the pad. An additional electrical connection function is achieved here when the pin is an electrical connector that contacts contacts in the pad.
Ein einfaches Befestigen und Lösen bei Herstellung, Montage und Auswechslung ist erreichbar, wenn das Befestigungsmittel über eine Rastverbindung an der Unterlage gesichert gehalten ist. Hierbei kann die Verstelleinrichtung des Befestigungsmittels mindestens ein in der Länge veränderbares Verstellelement aufweisen, das außermittig insbesondere am Rand das Tragelement oder die Platine mit der Unterlage verbindet. Auch wird vorteilhafterweise vorgeschlagen, dass zwei, drei oder mehr Befestigungsmittel insbesondere mit Verstellelementen am Rand des Tragelements/der Platine und/oder an der Unterlage befestigt sind.A simple attachment and detachment during manufacture, assembly and replacement can be achieved if the fastener is held secured by a locking connection to the pad. In this case, the adjustment of the fastening means may comprise at least one variable in length adjusting element which connects off-center, in particular at the edge of the support member or the board with the pad. Also, it is advantageously proposed that two, three or more fastening means are fastened in particular with adjusting elements on the edge of the support element / the board and / or on the substrate.
Herstellung, Montage und spätere Auswechslung werden erleichtert, wenn das Tragelement/die Platine an dem Befestigungsmittel durch eine Rastverbindung gehalten ist. Auch ist für die Herstellung und Montage von Vorteil, wenn das Tragelement/die Platine mit dem Befestigungsmittel einen modularen Baustein bildet.Production, assembly and subsequent replacement are facilitated if the support element / the circuit board is held on the fastening means by a latching connection. It is also advantageous for the manufacture and assembly when the support element / the board forms a modular component with the fastening means.
Eine präzise Begrenzung der auszuleuchtenden Fläche wird erreicht, wenn das Tragelement/die Platine oder die Unterlage eine die LEDs seitlich umgebende Blende aufweist. Dies wird noch dadurch verbessert, wenn die Blende um mindestens eine obere Blende erweitert ist, die die LED-Strahlung seitlich ablenkt.A precise limitation of the surface to be illuminated is achieved when the support element / the board or the base has a laterally surrounding the LEDs aperture. This is further improved if the diaphragm is widened by at least one upper diaphragm, which deflects the LED radiation laterally.
Eine exakte Bündelung der Strahlung jeder LED wird erreicht, wenn die LEDs von parabolförmigen Reflektoren umgeben sind.An exact concentration of the radiation of each LED is achieved when the LEDs are surrounded by parabolic reflectors.
