"Vorschaltgerät für Leuchtstofflampen - Leuchten" Beschreibung und Schutzansprüohe"Ballast for fluorescent lamps - luminaires" Description and protection claims
Das Vorschaltgerät für Leuchtstofflampen-Leuchten findet Anwendung als Strombegrenzer beim Betrieb einer Leuchtstofflampe am Netz.The ballast for fluorescent lamp luminaires is used as a current limiter when operating a fluorescent lamp on the mains.
Die Neuerung dient dem Zweck, eine Montage von mit Leuchtstofflampen bestückten Leuchten an normal-entflammbaren Flächen zu ermöglichen. Gemäß den einschlägigen Bestimmungen darf dabei an den Kontaktflächen eine gewisse Temperatur nieht überschritten werden.The purpose of the innovation is to allow luminaires fitted with fluorescent lamps to be installed on normally flammable surfaces enable. According to the relevant regulations, a certain temperature must not be exceeded on the contact surfaces.
Eine problematische Wärmequelle bei einer Leuchtstofflampen-Leuchte ist das Vorschaltgerät, in dem - besonders beim Kurzschluß - beträchtliche Wärmemengen entwickelt werden. Diese Wärme führt insbesondere, wenn das Vorschaltgerät innerhalb der Leuchte gegenüber der äußeren Befestigungsfläche angebracht ist, zu unzulässig hohen Temperaturen an der Kontaktfläche. Zur Erfüllung des oben genannten Zwecks muß daher das Vorschaltgerät wärmeisoliert befestigt werden.A problematic heat source in a fluorescent lamp is the ballast, in which - especially in the event of a short circuit - considerable amounts of heat are developed. These Heat leads in particular if the ballast is mounted inside the luminaire opposite the outer mounting surface is, excessively high temperatures at the contact surface. To achieve the above-mentioned purpose, the ballast must therefore be attached in a heat-insulated manner.
Es ist bekannt, daß eine hinreichende Wärmeisolation dann gegeben ist, wenn das Vorschaltgerät in einem Abstand von einigen Millimetern so angebracht ist, daß ein metallischer Kontakt nur auf einer geringen Fläche besteht. Diese Erkenntnis ist z.B. in einer An'.xlnung verwertet, wie sie das Gebrauchsmuster Nr. 1 996 582 wiedergibt ; dort werden als Distanzstücke Befestigunßslaechen oder entsprechend geformte Trägerbleche vorgeschlagen. Die Lösung hat den Nachteil, daß durch zusätzlich erforderliche Teile Kosten anfallen (Beschaffung, Lagerhaltung, Montage) und Fehlerquellen gegeben sind.It is known that there is sufficient thermal insulation when the ballast is at a distance of a few Millimeters is attached so that a metallic contact is only on a small area. This knowledge is e.g. used in an extension as reproduced in utility model no. 1 996 582; there are proposed as spacers fastening panels or correspondingly shaped support plates. The solution has the disadvantage that by additionally required parts costs are incurred (procurement, storage, assembly) and sources of error are given.
Aufgabe war daher, eine Einrichtung zu finden, die ohne Kostensteigerung eine Montage von Leuchtstofflampen-Leuchten an ent-The task was therefore to find a facility that would allow the installation of fluorescent lamp luminaires on
