The semiconductor lighting ferret saving potential
According to the U.S. Department of Energy’s Sandia National Laboratory, lighting energy consumption dataccounting for 8.9% of global energy consumption, accounting for 19% of the total electrical energy consumption contribution to GDP was only 0.63%. If general future lighting use semiconductor lighting products, the 2050 lighting electricity consumption is expected to maintain the 2005 level, and contribution to GDP ratio will rise to 1.63%. Semiconductor lighting industry as the new industry, it not only led lights to the development of related industries, creating new market demand, but also its wider application will greatly reduce the total electrical energy consumption to achieve energy savings.
China’s annual lighting electricity consumption is about 500 billion kwh, accounting for 13% of the total electricity consumption, accounting for 6% of the energy consumption and the annual growth rate of 5% -10% of the total electricity consumption of the whole year than the United Kingdom. LED light efficiency is much higher than traditional lighting and display light source, which showing good energy saving effect, such as 70% energy saving landscape lighting, backlight energy by 50%, 50% energy saving road lighting.
Experts predict that China’s semiconductor future lighting market share accounted for 30% of the general lighting market in 2015, the annual energy saving of about 100 billion kwh, reduce carbon emissions by 98.99 million tons, about one percentage point contribution to reducing energy consumption per unit of GDP; to market share, it can account for 50% of the general lighting market in 2020, the annual saving of about 340 billion kwh, equivalent to four total annual generating capacity of the Three Gorges Project.
The highest technical content epitaxy, chip development mainly in Europe and the United States, Japan and other developed countries, packaging applications are mainly distributed in Korea, China Taiwan and mainland China. With the accumulation of technical and financial aspects of LED manufacturers in Korea, Taiwan, and are actively to the upstream chips, epitaxial materials development in mainland China, due to the huge market prospects, and has become the hot spots of the global industrial transfer.
As technology continues to evolve at the same time, the continuous improvement of the luminous efficiency, the gradual expansion of the market, the price of LED lighting is also declining, the LED devices price of 50-60 $ /klm 2015 may be down to 1 /5. Semiconductor future lighting technology and its products forward higher luminous efficiency, lower cost, more reliable, more diversified field of development and wider application of direction.
