Abstract: Ceiling or wall fitted housings for illuminant integration comprise a base element, a wall element linked to the base element, as well as a supporting element that is installed opposite to the base element and that extends from the wall element in the side that faces away from the base element, whereby the wall element has a thread at least on its inside. The thread is directly pressed into the wall element of the fitted housing from the outside as a beading and extends as a bulge in the inner side of the wall.
