Shanghai semiconductor lighting industry chain formation is expected to save one billion kwh of electricity

In the near future, the Yu Garden night will be decorated by semiconductor lighting, not only more bright, but also become a pioneer in energy saving". With more and more iconic landscape and public lighting will be replaced by semiconductor lighting, Shanghai is expected to save 1 billion kwh of electricity per year, equivalent to a small city in a year's total lighting electricity consumption.

Semiconductor lighting (LED) is a kind of solid-state lighting, which is composed of light emitting diodes. Because there is no heat loss, the energy conversion efficiency is much higher than ordinary light bulbs. It is estimated that if 1/3 of the country's traditional lighting with LED substitution, the annual savings of electricity equivalent of a Three Gorges Hydropower Station; in addition, it also has the characteristics of environmental protection, long life, known as the history of lighting second "revolution". In 11th Five-Year, Shanghai science and technology planning, semiconductor lighting has also been included in the development of one of the twelve key strategic products.

LED lamp is not big, including substrate materials, epitaxial growth, chip manufacturing and packaging processes. As one of the five national semiconductor lighting industrial base, Shanghai not only has initially formed a relatively complete industrial chain, but also in the core of the epitaxial wafer, chip manufacturing, research and development of high-power packaging sectors, has Blaupunkt, Blu ray, morning photoelectric heavyweight enterprises to master more sophisticated technology and process, to avoid the foreign existing technology a result on the path, improve the LED light color, fresh brightness stability". As of the end of 2006, Shanghai has 105 LED related patents, the development of more than 100 national standards, industry standards and internal standards of the optical industry.

Open the map of Shanghai, a Zhangjiang technology development center in Pudong, Xuhui, Minhang, Jiading, Songjiang and other areas to support the radiation group LED industry map clearly visible. A compact "industrial baton", the LED dress up the city at night to become a reality. For example, the iconic landscape of Shanghai, the Oriental Pearl, the upper and lower body of the original use of a foreign company's incandescent lamp. After the transformation of the LED lamp, each spot power consumption is only 70W, saving nearly 75% of electricity consumption than the original. Moreover, according to the seasonal change of different color theme, through the performance of the LED lamp, but also more bright. Wujiaochang's new landmark eggs, the same can not be separated from the LED lights. 5 cm wide strip of LED lights cover the egg keel structure, hidden during the day, at night shine, won the praise of the public and experts.

Next, we want to let LED lighting into the homes of ordinary people. Shanghai semiconductor lighting Engineering Research Center for analysis, to achieve this goal must break through the two difficulties: reduce production costs and improve luminous efficiency. To this end, the center is to play the role of platform integration, Technology Institute, Shanghai Univer and other universities and research institutes of the existing research resources, the establishment of different professional evaluation function testing center, to further reduce the cost of corporate research. The next few years, Shanghai enterprises will aim at the white light 100lm/w industrialization key technology research. When the lights from the home to the front of the car, big lights, LED stage will be more broad.
