With over 2,200 manufacturersmaking LED devices, packages andluminaires today, China is advancing rapidlyto the forefront of Asia’s LED market.Although much of the country’s LEDindustry makes contract products for westerncompanies, the central and provincialgovernments, especially Guangdong Province,are aggressively developing their owninternal markets for high-quality, highbrightness,white-lighting applications.21 City, 10,000 LED Lights programIn 2009, the Ministry of Science andTechnology launched its “21 City, 10,000 LEDLights” program, the first phase of a muchlarger national demonstration project toinstall two million LED lamps in 50 cities.A key aim of the project is to enable LEDcompanies to deploy their LED products inthe cities where they are located, using largeinstallations as platforms for demonstration,for local investment, and to attract utilityorders. As a result, the Ministry providedsubsidies directly to the LED manufacturers– a 10% subsidy has been the norm – whichthen partnered with their local municipalgovernments. Here are some typical projects:Tianjin: A variety of outdoor LED demonstrationprojects were undertaken in 2010on the Tianjin Polytechnic University campus(see photo) and on the city’s streets, aswell as many indoor installations, totalingPhoto courtesy of Ryan Pyle.110,000 lighting fixtures.Hangzhou, Zhejiang province: An outdoordemonstration was undertaken of LEDluminaires along 21 km of the Jinghang orGrand Canal and in the vicinity of WestLake. A total of 65,000 outdoor and indoorLED lamps were installed.Dongguan, Guangdong province:Demonstration of 20,000 LED street lightson a variety of streets, supplied by local firmKingsun Optoelectronic, one of China’s oldestLED product manufacturers.Shanghai: Support for LED street-lightdemonstrations at the Shanghai World ExpoPHILIP JESSUP is a Senior Advisor to The Climate Group and to its global LightSavers initiative(www.theclimategroup.com/lightsavers).

Failure rates of 70% andannual lumen depreciation as high as 30%in some locales have been reported anecdotally.Hence, the project slowed in 2011 toallow time for evaluation by the China Solid-State Lighting Alliance (CSA).
