Abstract
Improvements in the construction of reflectors for light sources of elongated shape, intended for public lighting and that allows a plane of longitudinal symmetry that contains the major axis of the lamp arranged in the plane of the base of said reflector, characterized by the fact of structuring the reflector in a flat form and in such a way that it has two sets of reflection surfaces mechanically joined together, namely: a straight cylindrical surface forming the upper part or ceiling of the reflector and a lateral surface, the generatrices of said surface being supported straight cylindrical, horizontal and orthogonal to the major axis of the lamp, on a guideline constituted by a parabola arc that extends towards the rear by a line segment tangent to said arc extending as close as possible to the lamp, while the lateral surface is constituted, toward the rear, by a spherical surface that it joins each side of the plane of symmetry to a straight cylindrical surface of circular directrix, extending towards the front by a curvilinear surface whose sections by the horizontal planes and by the vertical transverse planes are arcs of parabolas and circles respectively.
