LED SIGNAL LIGHTING UNITS

SPECIFICATION NO. : RDSO/SPN/153/2011 Rev. 4.1

RDSO APPROVED. : YES

DESCRIPTION :

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. To simplify the application of LED Signals and improve reliability the Integrated LED Main Signals are developed. This is practically combining Current Regulator & Light Unit in one housing, keeping all the electrical, environment & Optical characters unaltered. Presently it is being used in Railway System with full satisfaction of the Railway authority.

 

TECHNICAL SHEET :

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
