Abstract (en)
[origin: EP1623904A2] The signal lens (100) has a front surface for emitting signal light into the surroundings. The lens has a uniform reflection behavior with respect to light incident on or in the lens from outside, and the behavior is independent of the location of incidence. The signal light is emitted to the surroundings only from within a defined fractional part of the front surface.
