The Hindu Business Line : Tirupati, Pulivendula get LED street lights

The temple town of Tirupati and Pulivendula, the constituency of late Chief Minister of Andhra Pradesh Dr Y.S. Rajasekhara Reddy in Andhra Pradesh, have street lights powered by light emitting diodes (LEDs).

Making this possible are NXP Semiconductors and Avni Energy Solutions Pvt Ltd, who have collaborated to develop the LED-based street lighting solutions.

This lighting solution is based on NXP’s SSL1750 SMPS controller IC, a part of NXP’s GreenChip product portfolio that has helped achieve power savings in the range of 60-70 per cent over the traditional lamps used, resulting in lower operating costs, a company release claimed.

The two firms implemented the pilot project entailing the installation of 400 lamp posts in Pulivendula and 250 in Tirupati, respectively. These lamps contain a set of 35–56 LEDs a panel (lamp), and consume between 50 W and 70 W of electricity.

The solution has the potential to reduce carbon emissions by up to 115 kg per lamp per year, and save approximately 160 W of power per lamp, which is enough to light up almost four homes using CFLs.

To illustrate the potential of this solution, replacing five million existing sodium vapour lamps equates to the power required to light up 20 million homes.

In addition, five million LED street lamps would reduce carbon emissions up to 575,000 tonnes per year, the release claimed.

The market for LED lighting is expected to grow significantly in coming years.

According to industry estimates, there is potential demand for up to 5 million units per state for street lighting solutions in India.
