LED lighting applications based on existing product range, can be divided into six categories: 1, outdoor landscape lighting: guardrail lamps, projection lamps, LED lights with LED profiled lights, digital tube, underground lamps, lawn lamps, underwater lights (market share of billions of dollars, hundreds of billion potential market). 2, interior lighting: wall lamps, chandeliers, embedded lights, spotlights, corner light, flat-luminescent panels, grid lamps, fluorescent lamps, downlights, change slide, mining lamps, stage lights, display, Downlight, Floodlight lights, lights, energy saving lamps, table lamps, kitchen lamps, floor lamps, wall lamps, ceiling lamps, night light, bulb lamp, bathroom lamp, mirror front lamps, water front, branch-like chandeliers (current market share of more than one billion million, the potential market of hundreds of billion). 3, special lighting: portable lighting (flashlights, headlamps), low-light lamp (Gallery lights, number plate lights, court with lights), reading lamps, microscope lamps, projection lamps, camera flash, table lamps, street lamps, (existing market The share of the billions of dollars, the potential market of several hundred billion). Security lighting: miner's lamp, explosion-proof lights, emergency lights, safety lights (existing market share hundreds of millions of dollars, billions of dollars of potential market). 5, special lighting: military lighting, medical non-thermal radiation lamps, therapy lamp, germicidal lamp, crops and flowers dedicated lights, biological lights, solar photovoltaic cells dedicated LED lights, (the little market share , but it has great significance and importance of the potential market of hundreds of billion). General lighting: offices, shops, hotels, household use ordinary lights such as LED lighting has yet to officially enter the field, but with the LED technology continues to progress and the declining cost of (expected within recent years will gradually into the general lighting field, the potential market is the largest, with hundreds of billions of potential for development).

China is now the major powers of the world photovoltaic production, but the market is mainly in foreign countries, especially Italy, Germany. The domestic market is still very small, but with the national policy, the domestic market is also gradually open, but it takes time. Government subsidies cut by the European countries in the entire PV industry this year, until now the market is not very good, and the size of the domestic enterprises, the market is a bit confusing, this market is not optimistic. From long-term to open the industry should still be, just need to wait for a long time.

2002, China in the western region "SDDX project in Qinghai Province, the construction of more than 100 solar photovoltaic power plants, because these plants were mostly built in the remote rural and pastoral areas, harsh natural environment, poor traffic conditions, personnel low levels of literacy, power plant operation and maintenance has brought some difficulties. From solar photovoltaic power plant operation and management of actual work experience, to ensure that the photovoltaic power generation system security, economic, efficient operation, and must establish a standardized and effective management mechanisms, in particular to strengthen the operation and maintenance of the power station management. Establish a sound technical document management system for each plant should establish a comprehensive and complete technical documents files, and the establishment of the person responsible for the management of the power plant technical documents, provide strong technical basic data to support the safe and reliable operation of the power station. 1. Establishment of power plant equipment technical file and design and construction drawings file basic technical archives of the power station, including: design and construction, as-built drawings; acceptance documents; equipment works, technical parameters, equipment installation procedures, equipment commissioning steps; all operations of the switches, knobs, handles, as well as state and signal indication; equipment running steps; power plant maintenance projects and content; maintenance schedule and all maintenance projects operating procedures; plant troubleshooting guide, including detailed inspection and repair steps and so on. 2. Establish power plant information management system
