Raumsparene gekapselte Leuchte insbesondere Strebleuchte für Schildausbau mit vier Lichtaustrittsöffnungen Space-saving, encapsulated luminaire, especially stray luminaire for shield extensions with four light exit openings
Die Neuerung betrifft eine gekapselte Strebleuchte in raumsparender Bauart, - zur Verwendung in Grubenbauen unter Tage, - die max. bis zu 4 Lichtaustrittsöffnungen besitzt. Als Leuchtkörper für derartige Leuchten dienen außer Glühlampen, - deren verhältnismäßig hohe Stromstärke sich dann ungünstig auswirkt, wenn eine größere Anzahl solcher Leuchten an ein Netz angeschlossen werden muß, - neuerdings sogenannte Kaltkathoden-Leuchtstoffröhren, denen jeweils ein Transformator zugeordnet wird, durch den die von der Kaltkathode der Leuchtstoffröhre geforderte hohe Spannung erzeugt wird.The innovation concerns an encapsulated stray luminaire in a space-saving manner Type of construction, - for use in underground mines, - which has a maximum of 4 light exit openings. As a luminous element for Such lights are used in addition to incandescent lamps, - their proportionally high amperage has an unfavorable effect when a large number of such lights are connected to a network must, - recently so-called cold cathode fluorescent tubes, each of which is assigned a transformer through which the Cold cathode of the fluorescent tube required high voltage is generated.
In. Betriebsräumen mit explosibler Atmosphäre kommt bei Verwendung von Glühlampen erschwerend hinzu, das die Lebensdauer einer Glühlampe unvergleichlich geringer ist, als die-einer Gasentladungs-Leuchtstoffröhre .In. Operating rooms with an explosive atmosphere are used of incandescent lamps added to the problem that the service life of an incandescent lamp is incomparably shorter than that of a gas discharge fluorescent tube .
Der Gegenstand der Neuerung b3trifft ein, in ein Stahlblechgehäuse mit 4 Lichtanstrittsöffnungen untergebrachtes 5-teiliges KaItkathoden-Leuchtstoffrohr, dessen Versorgungsteil in ein daran angeflanschtes zweites Gehäuse aus Stahlblech mit den entsprechenden V^rbindungs- und Anschlußklemmen für die innere Verdrahtung und Anschluß der äußeren Netzzuleitung untergebracht ist.The object of the innovation b3 arrives in a sheet steel housing 5-part cathode fluorescent tube housed with 4 light incidence openings, its supply part in a second housing flanged to it made of sheet steel with the corresponding V ^ rbindungs- and connection terminals for the internal wiring and connection of the external power supply line is housed.
Die Lichtaustrittsöffnungen im Gehäuse sind durch schlagfeste, wärmeformbeständige, UV-stabilisierte Schutzscheiben aus transparentem Polykarbonat abgedeckt. Die Scheiben durch Metallrahmen am Gehäuse unter Zwischenlage von Dichtscheiben gepreßt befestigt.The light exit openings in the housing are made of impact-resistant, heat-resistant, UV-stabilized protective panes made of transparent Polycarbonate covered. The panes are fastened by a metal frame to the housing pressed with the interposition of sealing washers.
In den Abbildungen ist ein Ausführungsbeispiel der Neuerung widergegeben.
