Abstract
Electric lamp, essentially characterized in that the incandescent filament is mounted inside the ampule on a support or a relatively short foot so that it is located approximately near the base of the neck of the ampoule or in the area of attachment of said neck and the sphere thereof, whereby the rays emitted by the filament inside, from certain angles of incidence, produce by refraction through the glass of the ampoule a total reflection, which due to the curvature of said ampule projects a beam bright and intense in the direction of the axis of symmetry of the lamp, this light beam being much higher than that obtained in ordinary lamps.
