LIGHTING ARMATURE FOR LIGHTING ENVIRONMENTS WHERE EXPLOSION HAZARD MAY EXIST

摘要

Disclosed is a lighting armature, which is provided with one or more built-in light sources (11), at least one built-in associated supply circuit for the light sources and provisions for electrical energy supply from outside the armature to the built-in supply circuit. The armature is suitable for use in environments where explosion hazard may exist. It includes a housing (1) and one or more light windows (2). The housing and the one or more light windows jointly enclose a space in which the at least one light source and the at least one supply circuit are arranged. The housing and the light windows are manufactured from materials which poorly transmit or do not transmit gas and moisture, so that gas and moisture can only poorly or cannot penetrate from outside the armature into the space. The space is filled with at least a non-explosive gas such as nitrogen.
