led street light (LightingEmittingDiode) that the light-emitting diode, is a semiconductor solid light-emitting device. LED lighting is called the fourth generation or green light, with energy-saving, environmental protection, long life, small size and other characteristics, can be widely used in various directions, display, decoration, backlight, general lighting and urban night scene and other fields. The current global energy shortage concerns against the backdrop of rising again, LED light source as a new type of green products is the future trend of development of the twenty-first century will be entered as the representative of the new led street light lighting times. 2008 Beijing Olympics to focus on led street light lighting display, and from 2007 onwards, Australia, Canada, the United States, the European Union, Japan and China Taiwan and other countries and regions have already announced that it would gradually phase out incandescent lamps, develop led street light lighting to become the focus of global industry . Ministry of Science and the lead organization to start "National Semiconductor Lighting Project\According to the production process, LED epitaxial film industry can be divided into upstream production, midstream chip manufacturing, chip packaging downstream of three parts, of which upper and middle reaches high technological contents, the most intense competition, operators are most at risk, but the most profitable. In the LED industry chain, LED epitaxial wafers and chips account for about 70% of the profits of the industry, led street light packaging accounts for about 10-20%, while the LED applications are accounted for 10-20%. Listed companies are currently involved in the field, mainly including three security photovoltaic (600,703) Hangzhou Silan Microelectronics (600.46 thousand) Linkage Optoelectronics (600,363), Fong A (000055), with the party shares (600100) Long Electric Technology (600,584), Fu Japanese Electronics (600203), st Shanghai Branch (600,608), BOE A (000725),, Gerber Group (600,622), et al. Among them, three opto-electronics and Hangzhou Silan Microelectronics is located in an industrial chain in upstream technology, a high level of strong profitability, gross profit margin maintained at over 40%, accounting for about 70% of industry profits. Linkage Optoelectronics (600,363) are concentrated in the midstream and downstream industry chain, Fong A (000055), with the party shares (600100) on the middle and lower reaches are involved in the industry chain.
