1. A trough-shaped lamp housing (10), which is integrally produced in a deep-drawing process, the lamp housing comprising:
a housing bottom (11) and a housing wall (12) which laterally surrounds the housing bottom (11) and which, together with the housing bottom (11), delimits a lamp chamber,
wherein the housing bottom (11) has a planar region (20, 25) for receiving at least one lamp component (120, 130) in a planar manner, wherein the planar region (20, 25) is circumferentially surrounded by at least one of a raised or recessed plurality of annular structures (35) which are integrally formed in a deep-drawing process, the plurality of annular structures all extending in a same plane, and
wherein the housing wall (12) discontinues at the circumferential edge thereof that faces away from the housing bottom (11) in a circumferentially closed edge portion (16), which lies in a plane, and
wherein at least two adjacent annular structures (35) are connected to one another by a channel-like recess (37) in the housing bottom (11).
