NXP and Avni collaborate to develop LED based street lighting solutions for India

NXP Semiconductor and Avni have collaborated to develop Light Emitting Diode (LED) based street lighting solutions for India that can replace the commonly used high-pressure sodium vapour lamps, which consume substantially more electricity. The LED street light installations have been deployed by the Tirupati and Pulivendula Municipal Corporations in the state of Andhra Pradesh.

The pilot project was recently implemented in Andhra Pradesh, entailing the installation of 400 lamp posts in Pulivendula and 250 lamp posts in Tirupati respectively. These lamps contain a set of 35 - 56 LEDs per panel (lamp), and consume between 50W - 70W of electricity. These lights offer dimming feature to reduce the amount of light during no-traffic time.

This lighting solution is based on NXP's SSL1750 SMPS controller IC.

NXP says, by using SSL1750 IC, LED lamps maximize energy efficiency, minimize form factor, and reduce heat generation to extend lamp lifetime beyond 50,000 hours. NXP adds, this solution has the potential to reduce carbon emissions by up to 115kg per lamp per year, and save approximately 160 W of power per lamp, which is enough to light up almost four homes using CFLs.
The power saving statistics: Replacing 5 million existing sodium vapour lamps equates to the power required to light up 20 million homes. So much for a power starved region.

Both governments and consumers are looking towards more efficient lighting options such as compact-fluorescent lamps (CFLs) and solid-state-lighting (SSL) to achieve these savings.

Mr. Ashok Chandak, senior director, global sales and marketing, NXP Semiconductors said, "The switch to low-energy solid state lighting is now a top priority for governments and enterprises across the world. The LED based street lighting solutions implemented in Andhra Pradesh is a case in point and illustrates the use of innovative semiconductor technologies to significantly help ease the burden that civic authorities face with regards to energy usage and maintenance of illuminated highways and streets. Using the NXP solution, sufficient lighting can now be maintained while operating at significantly lower
levels of electrical consumption, without the authorities having to switch off street lighting (which creates safety hazards) to save energy consumption."

"NXP is indeed one of the first semiconductor companies to identify the importance of energy-efficient lighting, and has made lighting a focus for more than 15 years," added Mr. Chandak while launching the campaign to bring light to millions of homes and reduce our carbon footprint through the use of innovative lighting technology solutions.

Mr. Kiran Kumar Reddy, Managing Director, Avni Energy Solutions remarked, "We are pleased to partner with NXP, which has supported us in closely developing a highly competitive and energy-efficient solution based on Solid State Lighting technologies. SSL1750 is a highly innovative and integrated solution that allows cost-effective power
supply designs and significant power factor correction in the range of 0.9 - 0.95, which leads the industry in terms of efficiency. The functionalities available in this solution will help us garner a competitive edge in our product portfolio".
