FIELD: physics.
SUBSTANCE: to generate green signalling light, a lens is made from green-coloured (3) light filters (1), through which the signal of the required green colour is formed, and from blue-coloured (C) light filters (2), through which a complementary colour signal is formed. The green signal, seen from afar in form of a whitish (whitish-yellow) light, when viewed together with the blue signal, will give the impression of light of the required green colour.
EFFECT: high reliability of correct recognition of the colour of signalling light at a large distance, low power consumption and simple design implementing the method.
