ALLAHABAD, September 5, 2009: In another step towards energy conservation, Indian Railways has decided to install special types of eco-friendly LED (Light Emitting Diode) based lights in the coaches of trains. Presently, small bulbs, CFLs (Compact Fluorescent Lights) are used for lighting purpose in the coaches of trains. Though these lights provide efficient lighting but they consume comparatively more energy than the LED lights. Further, they are also burden on the alternator and the batteries of the coaches. Pointedly, a Light Emitting Diode (LED) is a semiconductor device which converts electricity into light. Each diode is about 1/4 inch in diameter and uses about ten milliamperes to operate at about one-tenth of a watt. LEDs are small in size, but can be grouped together for higher intensity applications. LED lights are more rugged and damage-resistant than compact fluorescent and incandescent bulbs. LED lights don't flicker.
LED based Luminaire are more efficient, compact, quick light up in micro-seconds, ideal for use in applications that are subject to frequent on and off cycle, dimming feature, cool long life, more than 50 thousand hours, shock resistant, maintenance free and having no toxicity. There will be reduction of power consumption by 30-35 per cent on account of implementation of LED based coach lighting scheme. It would also reduce the burden on alternator and batteries of the coach which are being fitted in the lower part of the coach.
