Abstract

The present invention relates to a lighting appliance having reduced encumbrance with effective control of the photometric distribution of the emitted light which comprises at least one light source (13) interposed between a reflector (11) and an optical screen (14) and is characterized in that it comprises at least one light divergence limiting element (15a, 15b, 15c, 18) suitable for reducing the divergence angle of the light beams directed towards said optical screen (14).
