Abstract (en)
[origin: WO2011045663A1] LED-type luminous signaling device comprising one or more LED-type luminous emission sources (16) and at least a light-directing lens (14) able to diffuse the luminous radiation emitted by a corresponding LED-type luminous emission source (16) in at least one signaling direction. The light-directing lens (14) is conformed so as to define at least an interception portion (18) suitable to divert a predefined fraction of total luminous radiation emitted by each LED-type luminous emission source (16) in one or more control directions, different from the signaling direction, wherein the signaling device comprises optical detection means (17) disposed coherently with the control direction so as to detect said predefined fraction of luminous radiation diverted by the interception portion (18).
