Abstract

A dichroic lamp (20) with improved diffusion of light radiation, in which the rear surface of the lamp-shade (21) is directly in contact with a screen (24) having a dissipating capacity, obtained by the impact moulding of a metal plate; the screen (24) allows the iridescence created behind the distribution direction of the radiation emitted from the light source of the dichroic lamp (20), to be eliminated.
