Green energy saving is the main development direction of lighting products nowadays. Green lighting represented by LED lighting is constantly robbing the traditional lighting market. It is one of the irreversible trends that LED lights replace traditional bulbs. As China's strategic emerging industry and pillar industry of energy conservation and emission reduction, the lighting industry is entering the lighting market through energy-saving products represented by LED lights, and has continuously taken over the market share from traditional lighting. LED is a low voltage semiconductor point Cold Light Source. The theoretical advantages of LED light source, such as longer life, high efficiency, energy saving and environmental protection, have passed the test of practice, the performance parameters of LED light source are not improving as often said before, but are further improving. The overall development prospect of LED industry is generally optimistic. Policy support: LED semiconductor lighting is divided into three stages. In order to support the development of semiconductor lighting industry, China has planned three stages of industry development planning. Stage: by 2009, 1 million LED municipal lighting lamps will be applied in more than 20 pilot cities, of which LED municipal lighting lamps include not only LED street lamps for road lighting, it also includes tunnel lighting, subway car platforms, underground parking lots, gas stations and other public places. The target of localization of LED devices is 60. Expected annual power saving 2. 0. 2 billion degrees, this stage has been basically implemented; The second stage: by 2012, the construction of 50 semiconductor lighting demonstration cities will be completed nationwide, with 2 million LED municipal lighting lamps applied. The target of LED device localization ratio is 70, and it is expected that the annual power saving will reach 1 billion degrees; The third stage: by 2015, the chip localization rate will be above 70, white light LED10 yuan/thousand lumens, lamps 40 yuan/thousand lumens, replacing inefficient lighting products such as incandescent lamps and halogen lamps, semiconductor Lighting has entered the 30 general lighting market and is expected to save 140 billion degrees of electricity per year. LED lighting has obvious advantages to replace traditional lighting. The service life of LED lighting products is more than ten times longer than that of traditional products. It belongs to lighting products. Under the control of computers, it can be better programmed online and can be upgraded at any time. Therefore, it is more suitable for the development of digital informatization today. Importantly, LED lighting products conform to the concept of environmental protection. Because it has low energy consumption and belongs to DC drive, the power conversion between electricity and light can reach 100. Under the same lighting conditions, it can save more than 80 energy compared with traditional lighting products. According to the new forecast in the industry, semiconductor lighting sources will occupy of the market share in 2014 and semiconductor lighting lamps will occupy of the market share in 2016. Most people in the industry believe that the share of LED Indoor lighting products in 2020 may reach 50.
