PCT No. PCT/DK81/00113 Sec. 371 Date Aug. 10, 1982 Sec. 102(e) Date Aug. 10, 1982 PCT Filed Dec. 10, 1981 PCT Pub. No. WO82/02081 PCT Pub. Date Jun. 24, 1982.The fixture and shade, build together, for a tubular fluorescent lamp (20) comprises a shade provided with longitudinally extending limitation walls (10, 26) which on their inner-sides in cross sections follow a smooth concave curve. Within the shade transverse shade cross plates (12) are arranged evenly distributed along the length of the shade and fastened to the limitation walls (10, 26). A first and a second transverse shade and plate (18 and 16 respectively) are mounted one at each end of the shade. Said end plates (16 and 18) carries the sockets (48 and 50) necessary to receive the tubular lamp and defining between them the lamp axis (55) of the shade. The second end plate (16) is mounted at the one end of the shade limitation walls (10, 26), whereas the first end plate (18) is secured hereto in some distance from the opposite ends of these walls, at which ends the limitation walls are interconnected by a transverse outer wall (22). Within the transformer chamber (34 ), that is provided between said outer wall (22) and said first end wall (18), as the transformer (36, 38) of the fixture is arranged and it is connected to the socket (48) supported by the adjoining first end plate (18) through a hole in said end plate and to the socket (50) supported by the opposite first end plate (16) by means of conductors, preferably in the form of a two-conductor cable (32) arranged and guided within the shade. The first end plate (18) is provided with a lamp lead-in opening (56) placed excentrically relative to the shade lamp axis (55) and outside the circumference of the socket (50) mounted on this first end plate (16). Through said lead-in opening (56) a tubular lamp can be inserted in the shade by a longitudinal displacement, made possibly by each shade cross plate (12) being provided with such an elongated opening (60) that the tubular lamp (20) with its whole length can be inserted in the shirm by a longitudinal displacement parallel to the shade lamp axis (55) and then rest on the shade cross plates (12) for thereafter through the spaces between the shade cross plates to be gripped by hand, rotated and by a transverse displacement brought into engagement with the sockets (48 and 50). Such a fixture has a maximum height limited to the height of the shade and constitutes herewith a unit that can be arranged in a simple manner adapted to the available space and that ensures a possibility of a simple and safe renewal of the tubular fluorescent lamp (20). |
