March 31, 2008 – Vol.13 No.2 Philips Lumileds: LED Traffic Light Project in Guarulhos, Brazil Wins National Award The Brazilian government has awarded a first-place Rational Use and Energy Conservation National Award to electric power distributor Bandeirante Energia S.A. for replacing all the incandescent-based traffic lights in the Sao Paolo suburb with Philips Lumileds LUXEON LED-based lamps. The annual award recognizes initiatives that reduce the use of electric energy and/or oil or natural gas derivatives in favor of renewable sources. The new traffic lights in Guarulhos (population nearly 1.3 million) are cutting the city’s energy bills by approximately $240,000 annually and reducing municipal energy consumption by 1340 megawatt hours per year — enough to power about 558 average Brazilian households. The project cost approximately $750,000 and paid for itself in 12 months through a combination of energy savings and maintenance reductions made possible by long LED life.
The Guarulhos project involved the replacement of 5,370 incandescent bulbs used in 2,059 vehicular and pedestrian traffic lights with custom lamps using LUXEON LEDs. The lamp was developed and manufactured by Meng Engenharia Ltda, a Brazilian company specializing in signaling projects. The new lamp was designed to replicate the basic shape and radiation pattern of a traditional traffic head, using seven LUXEON I LEDs and a built-in power supply per bulb as well as a standard screw-in bulb base. This design enabled fast and easy field replacement with no need for specially trained work teams. All red, green and yellow traffic lights, arrows and pedestrian signals were replaced. Philips Lumileds is the world's leading provider of power LEDs for everyday lighting applications. (3/31/08)
