Abstract (en)
[origin: EP1452795A2] The device has a reflector (400) for reflecting luminous rays produced by a luminous source that consists of series of electroluminescent diodes (401). Each electroluminescent diode is oriented in such a manner so that a part of its radiation attains a specific zone (403-p1 to 403-p3) of reflection on the reflector. Each specific zone provides a specific light distribution in the production of the luminous rays.
