Innerhalb der Durchlichtscheibe ist im Gehäuse ein Lichtleit- oder Blendschutzgitter angeordnet, das auf Stützrippen der Gehäusewände aufsitzt.Within the transparency, a light guide or anti-glare screen is arranged in the housing, which rests on support ribs of the housing walls.
Bei dieser Einbauleuchte ist das Zuschneiden der Gehäusewände auf Gehrung sehr zeitaufwändig und somit kostenträchtig. Auch das Abdichten der Stoßfugen ist problematisch.With this recessed luminaire, the cutting of the housing walls mitred is very time-consuming and thus costly. Also, the sealing of the joints is problematic.
Die die frontseitige Öffnung des Gehäuses abdeckende Durchlichtscheibe ist mittels eines zusammenhängend umlaufenden Klebstoffbettes auf den Glasträgerleisten befestigt.The translucent lens covering the front opening of the housing is fastened to the glass carrier strips by means of a contiguous adhesive bed.
Solche Einbauleuchten werden gewöhnlich in Werkzeugmaschinen eingebaut, die in einer Gehäusewand, in welcher die Einbauleuchte befestigt werden soll, eine entsprechende rechteckige Einbauöffnung aufweisen.Such recessed lights are usually installed in machine tools, which have in a housing wall in which the recessed light is to be attached, a corresponding rectangular mounting hole.
In Werkzeugmaschinen, die spanabhebende Arbeiten verrichten, kommen die Frontseiten der Einbauleuchten in der Regel mit chemisch aggressiven Kühl- und Schmierstoffen in Berührung. Es ist deshalb unerlässlich, das gesamte Gehäuse hermetisch abzudichten, damit keine aggressiven Gase und/oder Flüssigkeiten in das Gehäuseinnere eindringen können. Weil auch die derzeit zur Verfügung stehenden Klebstoffe, die zur Befestigung der Durchlichtscheibe auf den Glasträgerleisten benutzt werden, nicht ausreichend gegen die aggressiven Kühl- und Schmierstoffe resistent sind, ist es auch erforderlich, das Klebstoffbett, das zwischen der Durchlichtscheibe und den Glasträgerleisten angeordnet ist, davor zu schützen, mit den aggressiven Kühl- und Schmiermitteln bzw. von diesen ausgehenden Gasen in Berührung zu kommen.In machine tools, which do the cutting work, the front sides of the recessed luminaires usually come into contact with chemically aggressive coolants and lubricants. It is therefore essential to hermetically seal the entire housing, so that no aggressive gases and / or liquids can penetrate into the housing interior. Because the currently available adhesives used to attach the translucent lens to the glass support bars are not sufficiently resistant to the aggressive coolants and lubricants, it is also necessary to use the adhesive bed disposed between the translucent glass and the glass support bars. protect against contact with the aggressive coolants, lubricants or gases emitted by them.
