Solar LEDs, chips to power India’s lighting future

BANGALORE: Streetlights in the city of Tilburg in Europe can detect the presence of approaching pedestrians and vehicles and ramp up the brightness in front and behind the person/vehicle as they pass by. The streetlights automatically dim when there is no one in the street. This technology, called LumiMotion, developed by Philips, uses sensors to make streetlights power efficient and cut carbon imprint.

 According to Indranil Goswami, head (controls), Philips Lighting India, “different kinds of sensors have been developed for intelligent public lighting management systems. Photocells detect the presence of sunlight and turn on and off lights. This alone can save up to 10% energy because of the difference in sunrise and sunset times in summer and winter,” says Goswami. He says the company has aggressive plans to deploy technologies like this in India, reflecting a global trend where chips are playing a vital role in power management.”Lighting is a power hungry field, taking up about 20% of the world’s electricity. A lot of current is needed to light the arc. But if you control how the arc is lit, about 25% of the power intake can be cut,” says Warren East, the global CEO of ARM. Chips based on ARM design, which are found in 95% of the smartphones, are now being used in streetlighting, healthcare gadgets and even by farmers, because of its power efficient design.

    yes can save 10 % of 10 % , but at low level saving will be offset by higher loses in system components due to incresed harmonics . idea has good acedemic and seminar content

    True!! At low level the losses are high due to increased harmonics but for street lighting applications level this seems feasible.
