ABSTRACT:
An improved built-in ceiling light. The dimensions of openings provided in false ceilings for the installation of built-in ceiling lights result in light housing dimensions which do not always provide the necessary storage space for the electrical components, in particular the ballast. It is known to obtain this necessary storage space by means of a projection from a side wall on the side of the housing base. However, this impedes the installation assembly. To avoid this difficulty the improved ceiling light has a projection which is a lid pivotally mounted to a housing base and to which the electrical components are attached. Then, during the insertion of the light housing, the lid, together with the electrical components, can be pivoted sufficiently far through a rectangular opening in a longitudinal side wall into the light housing.
