Abstract (en)
[origin: WO2013144005A1] The object of the present invention is a procedure for construction of a rotational asymmetric assembled reflector (6, 12) for projectors for lighting installations, with an angle of asymmetry, a, between an axis corresponding to a light beam of maximum light intensity and an axis orthogonal to a light output plane, comprising construction of a rotationally symmetrical solid (5, 10) symmetrical with respect to an axis of rotation (X), formed by two rotationally symmetrical solids (65, 66, 125, 126) having a same tangent plane (69, 129) at common points (68, 128) along a conjunction line (67, 127) of said rotationally symmetrical solids (65, 66, 125, 126); cutting of said rotationally symmetrical solid (5, 10) according to a cutting plane (60) inclined to an axis (Y) orthogonal to said axis of rotation (X), by an angle corresponding to the said angle of asymmetry, a, aimed at obtaining two parts (51, 52, 111, 112); rotation of about 180 ° of one (52, 112) of the two parts obtained by means of said cutting around an axis orthogonal to a plane (X, Y) containing said axis of rotation (X) and its orthogonal axis (Y); assembling of the parts (51, 52, 111, 112) thanks to connecting means (61, 121); overlapping of a quantity (OL) of one part (52, 112) with respect to the other part (51, 111); adjustment of the inclination of the parts (51, 52, 111, 112) according to a optimum light performance; assembling (62, 122) of the parts (51, 52, 111, 112). (Fig. 10).
