The warning lamp for an aircraft is provided with a housing (10) which possesses a light permeable cover (12) that is exposed to the surrounding air when the housing is mounted on the aircraft, with a frontal cover area and a rear cover area, a mounting element (44) to fasten the cover to a lower part (14) of the housing (10), wherein one edge (41) of the cover (12) is covered by an edge of the mounting element (44) and protrudes from it, a lamp with at least one LED (42,46,58,60), which is arranged within an area that is covered by the cover (12), and a cooling body (18) for the at least one LED (42,46,58,60), wherein the cooling body (18) possesses a cooling surface (32) that is exposed to the surrounding air when the housing (10) is mounted on the aircraft. The frontal cover area is formed by a frontal cover element (22) which is made from a light permeable first material. The rear cover area is formed by a rear cover element (28), which is made from a light permeable second material. The cooling body (18), while separating the frontal cover element (22) from the rear cover element (28), is arranged between them, wherein its cooling surface (32) is a part of the external contours of the cover (12) of the housing (10) that is given by the frontal and rear cover elements (22,28) and possesses an upper region (38) as well as adjacent, opposing side areas (40).

摘要:
The invention concerns a method and apparatus for production of a hollow section (1) in which a coiled pre-shape of the hollow section (1) is deep drawn from a sheet part, which is pre-bent after a trimming process and coiled into the final shape of hollow section (1). The edges (45) of hollow section (1) lying in the peripheral direction are then joined together in the contact region. In order to improve the joining capability of hollow section (1) to other components in simple fashion, it is proposed that before the coiling process at least one flat site (35) for joining to another component be embossed before the coiling process in a pre-bent region of the hollow section (1).
