Semiconductor lighting (light-emitting diode, English abbreviation: LED) is a new type of solid-state light source, which has shown energy-saving effects in special lighting fields, such as landscape lighting (replacement of neon lights) 70% energy saving, traffic lights (alternative incandescent lamps) energy saving 80% .
At present, LED luminous efficiency is higher than incandescent lamps. It is expected to exceed fluorescent lamps in 2010, and it is expected to enter the general lighting field, which accounts for 15%-20% of global power consumption. The effect of energy saving will be more significant. Combining its low power consumption and long life, under the circumstances of global energy crisis and environmental protection pressure, semiconductor lighting has been recognized as an important way of energy saving and environmental protection in the world, and it is expanding its variety at a faster speed. Application range.
With the continuous improvement of technology, large-size LCD TV backlights, automotive, commercial and industrial lighting have gradually become the main application areas of LED. In 2006, the global LED market exceeded US$7 billion, with an average annual growth rate of more than 20%. In the next 5-10 years, it will form a potential market of more than US$500-100 billion. In view of the encouraging development prospects of the semiconductor lighting industry, Japan has recently Government plans such as the 21st Century Light Project, the US “Next Generation Lighting Projectâ€, the EU “Rainbow Projectâ€, and the Korean “GaN Semiconductor Luminescence Program†have been launched. Faced with the huge temptation of the semiconductor lighting market, the world's three traditional lighting industry giants Philips, General Electric, and OSRAM also cooperated with semiconductor companies to establish a semiconductor lighting company. A battle to seize the commanding heights of the emerging industries of semiconductor lighting has already started around the world.
