Lamp holder and methods for their mounting

Lamp holder (10), with a lamp support (11) having a light emitting center area (12) for mounting at least one semiconductor light-emitting means (13), with a holding part (20) which is for mounting the luminous means holder (10) arranged on a lighting device, with a holding device (27) on the holding part (20) that holds the light source carrier (11) on the holding part (20), with a cover (37) having an emission opening (38) in a circumferential direction (U) is the radiation opening (38) by a pressing arrangement (40) with at least one contact body (39) is limited, with a fastening means (45) which is adapted for attachment of the cover member (37) on the holding part (20) to produce a non-positive and / or positive, releasable connection, wherein the fastening means (45) on the holding part (20) at least one mounting surface (46) and on the cover (37) each having an associated counter-attachment surface (50) which abut at fabricated fastening between the cover (37) and the retaining part (20) to each other wherein the attachment surface (46) (47) of the holding part (20) is provided on a resilient mounting projection, having said at least one mounting surface (46) and / or the at least one counter-mounting surface (50) in the circumferential direction (U) sloping first surface portion (50a) and an adjoining, in the circumferential direction (U) tilt free second surface portion (50b) wherein the at least one contact body (39) adjacent the lamps surface (12) on the light source carrier (11) presses at fabricated fastening between the cover (37) and the holding part (20) and a pressing force in a pressing direction (R) is generated.
