New Delhi: To save energy and provide a better experience, Metro Delhi replaces an existing conventional lighting system with LED lights in 155 locations, which includes stations, depots and parking lots, officials said on Sundays.
This was done as part of a massive drive starting earlier this year, and about one lakh LED light was installed with a brave replacement in recent months, they said.
“To save energy and provide a much better lighting experience, Metro Delhi has done a large drive to replace existing conventional lights (incandescent lamps, neon lights, CFL lights etc.) with LED lights in 155 locations that include metro stations, depots, Parking etc.
which was built or opened to the public under the PH-I DMRC (2005) and PH-II (2010), “DMRC said in a statement.
DMRC has covered 75 percent of the drive in the past few months by installing around one lamp lamp Lakh in these locations by replacing conventional lights, a senior official said.
The remaining 25 percent of the drive will be completed at the end of October this year, where around 35,000 LED lights will be installed in the remaining part of this location, he said.
The operational life of conventional lights, which are installed in PH-I and PH-II are around 10 years.
DMRC decided to replace these lights that have passed their effective age now with this new LED light which both cost and save energy.
LED-based light systems will help DMRC save about half of existing energy expenditure vis-a-vis lighting systems.
As a result, all the costs of installing this lamp will be restored by DMRC in about two years, the statement said.
LED system age is longer than existing conventional lights, with reduced maintenance costs.
On average, the LED system lasts 50,000 hours of operation or more, he said.
LED sources are more than 40 times higher in age than incandescent light bulbs.
In addition, LED lights have energy efficiency components that make it consume very low amount of power, officials said.
Doing this drive at the operational station has become a challenging task for the DMRC maintenance team, he said.
Because there are ordinary people’s movements, work must be executed within night for security reasons which in turn increases installation time, officials said.
“Even at night, work can be done for about two hours just a day since the time windows available from the closing of the last passenger service and the start of the first passenger service is very limited, and other important operational care activities and other routine maintenance activities are carried out in this period , “DMRC said.
DMRC must set the scaffold and special crane to cover the room twice or three times it becomes a normal high building that is once again very complicated and the exercise takes time, he said.
DMRC has implemented LED-based lighting solutions at phase-III stations and similar systems will be adopted for future phase-IV stations, officials said.
