Abstract

1504689 Electric lamps J A ORAM 18 April 1975 [18 April 1974] 17083/74 Heading F4R A sealed lighting device, e.g. for machine tools, comprises an electric lamp 54, e.g. a tungsten-halogen lamp, in a metal housing 1 to which heat is conducted from the lamp by a ceramic ring 38, a transparent cover-plate 35, a rear cover-plate 55 and a cable entry assembly, all sealed to the housing 1. As shown, the lamp 54 is located within the ceramic ring 38 by a circular metal strip insert 46 in thermal and electrical contact with the lamp. The lamp is held in place by a spring 62 so that the filament is at the reflector focus. The housing is mounted for limited angular movement on a spigot support 18 to which the cable is sealed. The lamp is operated by a switch 32 controlled by a rotary knob 28. In an alternative arrangement, the strip metal insert is replaced by a square section ring (110) (Figs. 7, 8, not shown) with a radial hole for receiving a wire end.
