Abstract (en)
Lighting device (1) comprising a non-parabolic reflector (3) with a continuous complex reflective surface that directly distributes the light beam in accordance with the regulations without the use of an external diffusing lens. The reflective surface is made up of four surface portions (4) generated by reflecting a portion bounded by a horizontal section line (5) and a vertical section line (6). The horizontal and vertical section lines (5) and (6) are chosen to provide the desired distribution of the luminous flux on the section in question and one is then transformed continuously into the other along a guide line (7) to generate the intermediate sections (15) in such a way that each point on the horizontal section line is moved to a corresponding point on the vertical section line. <IMAGE> <IMAGE>
