Abstract (en)

[origin: EP0485811A2] The invention relates to a light fixture, in particular a recessed light fixture, having a fixed outer housing (1), and swivallably arranged lamp housing (2) and lamp holder (3). The lamp housing (2) supporting the lamp holder (3) is joined to the outer housing (1) by a guide rod arrangement (4). According to the invention, the guide rod arrangement (4) has at least one pair of guide rods made from one-piece guide rods (5, 6) constructed with different lengths, the two guide rods (5, 6) forming with the lamp housing (2) a four-bar linkage having only one degree of freedom of motion. The kinematics of the four-bar linkage is so arranged that the swivelling movement of the lamp housing (2) is necessarily superimposed with the sideways and downwardly directed motion of the lamp housing (2). <IMAGE>
