Abstract

A long-life lighting device, comprising, in combination, a casing 11 containing a rotatable support element 12, which is provided with an outward facing aperture 14 on which is placed an optical covering element 15 and a fixed reflecting portion of parabola 16 which can be supplemented with at least a pair of movable reflecting portions of parabola 17 which are associated with the rotatable support element 12 and are located one after the other in the direction of rotation, and each of which contains at least one lamp 13, the rotatable support element 12 being linked to a rotary drive element 25 which can be activated by an external control means; additionally, contact elements 31, 32; 34, 35 are provided for activating the lamp 13 contained in each movable portion of parabola 17 when the latter is positioned adjacent to the fixed portion of parabola 16 to form a whole concave reflecting parabola. <IMAGE>
