Abstract
1. Exhaust air lamp for a rod-shaped lamp(3) with a housing having a light exit aperture (100) delimited by side walls (11, 12) and with a housing roof (10) parallel to the light exit aperture and extending between the side walls, having at least two exhaust air apertures (110) in the side walls (11, 12), each of which has a cross-section of at least 20 cm**2, having a reflector insert (2) with a channel-shaped reflector (20) for each lamp (3), having side reflectors (201, 202) on both sides of the lamp (3) and a roof reflector (200) arranged between them, and having an exhaust air gap (204) between a side reflector (201, 202) and the roof reflector (200), characterized in that the housing height (e) is a maximum of 100 mm and the housing roof (10) is constructed as a roof reflector (200) on the inside between the side reflectors (201, 202), in that each exhaust air aperture (110) overlaps a housing edge (111) and consists of a side hole (1101) in the side wall (11) of the housing and a roof hole (1102) in the housing roof (10), in that the hole depth (a1) of the roof hole (1102) is equal to or smaller than the reflector width (c), projected onto the housing roof (10), of the side reflector (201) adjacent to the side wall (11) of the housing.
