Profile element (1) for receiving
electric light sources and for arrangement in or on a
floor covering, wherein the profile element (1) has a housing element (2, 29, 30) extending along a direction of extension, with a bottom surface (4) suitable for fixing to a substrate (9) and with two opposing side walls (5, 6), wherein the housing element (5, 6) surrounds a cavity (7) extending in the direction of extension and arranged between the two side walls (5, 6), in which at least one
electric light source can be arranged, and wherein the profile element (1) has a cover element (3) also extending along the direction of extension and detachably connectable to the housing element (2, 29, 30), which covers the cavity (7) and is made at least partially of a translucent material or has openings,so that light emitted by the
electric light source in the cavity (7) can exit the profile element (1) through the cover element (3), characterized in that the housing element (2, 29, 30) has on its underside (4) opposite the cover element (3), with which the housing element (2, 29, 30) can rest on the substrate (9) as intended, a support projection (10) extending inwards into the cavity (7), which forms a
support surface (11) for receiving the electric
light source, spaced apart from the underside (4) and extending in the direction of extension, and in that the housing element (2, 29, 30) has a drainage channel (12) extending alongside the support projection (10) in the direction of extension, in which
moisture penetrating the cavity (7) can accumulate spaced apart from the
support surface (11) and be drained away in the direction of extension. can.,
