The Air-Conditioned coaches in the railways presently rely on conventional lighting system, which uses fluorescent lamp based lighting, with bulk inverter units. The present system does not provide quality lighting, and moreover has major lifetime issues. A survey of existing lighting solutions in the air-conditioned railway coaches has been performed. The analysis, helped in understanding the design limitation and flaws of the existing lighting scheme, and aided in the selection of the best fit LED for the desired specifications. The revamped illumination scheme proposed was able to cut down the power consumption by 50% than the existing conventional lighting scheme, providing improved linearity in lighting distribution, giving an aesthetic feel to the area. Other important features are its exceptional long life and the recurring saving on maintenance than its predecessors. The proposed system eliminates the use of inverter for the luminaires, thereby improving the overall system efficiency, by eliminating conversion losses in the inverter. The LED used are in compliance with ROHS and free of Ultra-violet radiation, which makes the luminaire an Eco-Friendly one.
