Abstract
Optical system for electrical lighting apparatus, constituted by a piece molded of transparent material of truncated cone shape and of a warped generatrix that is located below the plane coincident with that of the equator of the light source, said part being in its upper portion, that is to say the closer to the lamp, an annular zone that constitutes a prism of relatively high and protruding revolution, which works at the same time by reflection and refraction, receiving the incident flow coming from the lamp, which is oriented by total reflection on the external face of the lamp. prism and refracts it downwards when emerging from it, producing a convenient dispersion of the light rays, and also comprising in the rest of the surface warped to the central opening of the lower part of the piece, a succession of immediate prisms located in planes lower parallels, which work only by refraction, remaining in the lowest part of December has piece, an open area for the passage of cooling air.
