The present invention relates to an assembly () having: a component body (), and a fastening body () for fastening the component body (), wherein the component body () can be connected to the fastening body () via a bayonet closure () of the assembly (), wherein the bayonet closure () has: a bayonet projection (), and a bayonet groove () in and along which the bayonet projection () can be guided, wherein the bayonet groove () has: an introduction portion () via which the bayonet projection () can be introduced into the bayonet groove () in an introduction direction (E), a function portion () which extends away from the introduction portion () laterally in relation to the introduction direction (E) and opens at a distal end of said introduction portion in a locking portion () for fixing the bayonet projection (), in which locking portion the bayonet projection () can be fixed in a locking position, a blocking portion () which connects the function portion () to the introduction portion (), and a pocket portion () extending away from the function portion () counter to the introduction direction (E) between the blocking portion () and the locking portion (), in which pocket portion the bayonet projection () can be at least partially received in a holding position, wherein the assembly () furthermore has a blocking element () which can be positioned selectively in a blocking position in the blocking portion () in order to block a passage for the bayonet projection () in the bayonet groove () between the introduction portion () and the function portion (), and wherein the assembly () is designed such that the blocking portion () is at least partially exposed in the holding position in such a manner in order to position the blocking element () in the blocking portion ().

Assembly having a bayonet closure

The invention relates to an optical system () for lighting units (S), having: an optical support () which extends linearly along a longitudinal axis (A) between a light inlet opening (LE) and a light outlet opening (LA) and which delimits a receiving area (R) for receiving optical elements () between the openings (LE, LE), wherein an inner wall () of the optical support () facing the receiving area (R) has at least two structural sections (), which are axially offset to each other with respect to the longitudinal axis (A), for releasably mounting a respective optical element () in the receiving area (R).

Adjustable optical system for lighting units

Disclosed is a downlight () comprising an annular mounting frame () to be mounted in the area of a ceiling mounting hole, and a light fixture () that is to be fastened to the mounting frame () and includes a luminaire head () thereon. The mounting frame () and the light fixture () are designed such that the light fixture () is fastened to the mounting frame () by twisting the former () relative to the latter (), additional securing means being provided which prevent the light fixture () from being twisted in the unlocking direction in a mounted position.

Downlight

Disclosed is a downlight () comprising a mounting frame () to be mounted in the area of a ceiling mounting hole, and a light fixture () that is to be fastened to the mounting frame () and includes a luminaire head (). The light fixture () is formed by a substantially C-shaped element having a main surface () and two angled wings () on two opposite sides of the main surface (); the wings () of the light fixture () are designed in a flexible manner and in such a way as to interlock with the mounting frame ().
