LAMPE PORTATIVE COMPORTANT UN DISPOSITIF DE COMMANDE ELECTRIQUE DE LA GEOMETRIE DU FAISCEAU ELECTRIQUE

摘要

The invention relates to a portable electric lamp with a light source generating at least one light beam; and a pane of glass arranged in front of the light source. The pane of glass has an electro-optical diffusion device controlled by an electrical signal in order to generate electrically adjustable diffusion. This diffusion generates a light beam with variable geometry from the single narrow beam. This results in headlamps with improved control of the geometry of its lightbeams.
