LED Signal Lighting Units manufactured as per Railway Specification No. RDSO/SPN/153/2011 Rev. 4.1 can help the Railways to cut their operating costs dramatically. LED Signal Lighting Units, however, require very little maintenance, have a long service life and offer high availability.Applications:-.LED Signal Lighting Units are designed to suit the existing signal lighting circuits and mechanical fittings without any modifications. Therefore the interlocking system and proving mechanism remains unaltered..The LED Signal Lighting Units give reliable operation for period of more than ten years, practically without any maintenance and service..Red, Yellow, Green and Lunar White LED Lighting Units are designed to meet various signaling requirements.   Benefits of the system:- . Negligible maintenance. Gives very low life-cycle cost. . LED is a solid-state device, hence the LEDs are highly reliable (life 10 years approximately). . The system is free from coloured glass lens breakage problem. . Power consumption is less. . Illumination does not vary with supply voltage. . Shifting of colours is very slow. . Illumination is higher. . The signal remains useful when any individual LED fails as the array does not go blank.
