Abstract
Smart LED signal lamps for external lighting signals in railway signalling technology with LED diodes (4) is divided into three independent LED compartments (9), where the light signal from only two LED compartments (9) is sufficient for complying to relevant standards for optical properties of these lamps. Functionallity of each LED diode (4) is checked through three independent procedures. Overview of functionallity of control and monitoring electronics of each compartment (9) of LED signal lamp is carried so that the control of functionallity of suppling electric energy by the feeding sources (11) so that each possible deffect is detected and will not cause deffect to the LED signalling lamp, whereby preserved are the main principles of safety for passing through and warning signals.
