N-DIGIT TRAFFIC LIGHTS Russian patent published in 2017 - IPC B61L5/12 B61L5/18 G08G1/95 

FIELD: physics.

SUBSTANCE: invention relates to the regulatory or warning devices positioned along the route of the locomotives or trains, namely, the traffic lights regulating the movement of the trains. According to the invention, M multi-colour LEDs are inserted into the N-digit traffic light, the device inputs are the control inputs and the common input. Each control input is connected to the M anodes of the multi-colour LEDs of the same colour, the common input is connected to the M cathodes of the multi-colour LEDs. Light indication is determined by the result of mixing K colours of the switched-on LEDs that make up the multi-colour LEDs.

EFFECT: design of the traffic light is simplified, and the quantity of its signal indications is increased.
