the mounting frame 50 has an angled configuration having a flange 51 directed outward which bears against the ceiling in the installed state as well as a circumferential ridge 52 extending through the hole in the ceiling the circumferential flange region 51 which then forms the actual mounting hole for the other components of the downlight with its inner edge serves to compensate for or cover any irregularities in the ceiling mounting hole this flange 51 is frequently partially plastered over after it has been attached to the ceiling such that a particularly inconspicuous transition is obtained between the ceiling and the other elements of the lamp 100 the attachment of such a mounting frame 50 to the suspended ceiling can be achieved by a number of methods wherein screw connections are known for example which would also be suitable in the present case in this case the outward protruding region of the flange 51 normally has a hole pattern or the like which simplifies the screwing to the sheetrock ceiling in contrast the attachment occurs with the depicted exemplary embodiment by means of special locking elements 55 which are distributed about the circumference of the mounting frame 50 these locking elements are formed in particular by height adjustable and outward pivotable tabs which are first oriented vertically downward in the.
