1. International understanding, judgment and practice of the semiconductor lighting industry
Semiconductor lighting, also known as solid-state lighting, has the characteristics of low power consumption, long life, and strong controllability. At present, the light efficiency of products has surpassed that of ordinary lighting such as incandescent lamps, halogen lamps, fluorescent lamps, etc., and the price is rapidly declining. In the history of the revolution of illumination sources after incandescent lamps and fluorescent lamps.
(1) Semiconductor lighting is a revolutionary technology with huge innovation space and technological progress
At present, the development speed of semiconductor lighting technology and market has far exceeded people's expectations. At present, the efficacy of power-type white LED products has exceeded 100 lumens / watt (theoretical value is 400 lumens / watt, research and development has reached 161 lumens / watt), greatly exceeding the ordinary lighting incandescent lamps (15 lumens / watt) and energy-saving fluorescent lamps (90 lumens) / watt), and began demonstration applications in the field of general lighting. The multi-disciplinary integration of the semiconductor lighting industry is characterized by deep physics, difficult chemistry and complex device technology, including optical, electrical, thermal and many other disciplines, with huge scientific and technological progress space and development potential.
(2) Semiconductor lighting is a strategic industry with huge market potential
Since the 1960s, LED indicators have shown that low-end applications have gone 50 years in the development of 100 years, while high-end LED functional lighting applications in the 100-year development process from the 1990s So far, only 10 years have passed. According to the United States Strategies Unlimited company data, from 1999 to 2008, the global LED market size grew at an average annual rate of more than 20%. With the maturity of technology and the rapid decline in cost, semiconductor lighting has been launched in the huge functional lighting application market of roads, industrial and mining enterprises, commercial buildings and homes. In addition, new applications such as medical, agricultural, military, and aviation have emerged, and the prototype of indoor lighting with greater market space is gradually taking shape. It is estimated that in 2015, the global market for semiconductor lighting applications will be more than 100 billion US dollars.
(3) Semiconductor lighting is a green light source that is energy-saving and environmentally friendly
According to a paper submitted to Nature by the Sandia National Laboratory on July 21, 2007, lighting accounts for 8.9% of global energy consumption, 19% of electricity consumption, and only 0.63 of GDP. %. If semiconductor lighting technology is adopted, it is expected that the lighting power consumption in 2050 will be maintained at the level of 2005 (8% of energy consumption and 20% of power consumption), but the contribution rate to GDP will rise to 1.63%. LED production and use without harmful substances such as mercury, can greatly reduce the environmental pollution of used lamps, and use low-voltage DC power supply, no infrared, ultraviolet radiation, is a truly green, healthy lighting source.
(4) The battle for seizing the commanding heights of strategic industries has started globally
Faced with the huge market space and energy-saving potential of the semiconductor lighting industry, many developed countries have listed semiconductor lighting as a strategic high-tech industry. A battle for seizing the commanding heights of emerging industries has already started around the world. The main practices of developed countries and regions to support semiconductor lighting technology innovation and industrial development are:
1Based on national strategy to promote the development of semiconductor lighting technology
The US National Semiconductor Lighting Research Program (US$500 million investment in 2000-2010), the United States has now raised the development of semiconductor lighting technology to the height of national strategy, and the US Department of Energy's research and development plan will ensure that US companies can be in the next generation. The field of lighting technology continues to maintain a strong competitive edge â€“ using the power of the state to realize the strategic interests of the future. In addition, the EU's "Rainbow Program" (2000), South Korea's "GaN Semiconductor Development Plan" (2002) and other developed countries' government plans have been launched, and China's Taiwan region also launched the "New Century Lighting Source Development Plan" in September 2002. . When the "21st Century Light Project" (1998) was launched in Japan, the LED light efficiency was less than 10 lumens per watt, but the Japanese government boldly expected 100 lumens per watt in the ten years from the perspective of energy conservation and environmental protection, reflecting the national will. Challenge scientists and entrepreneurs.
2 Released the prohibition order for high-energy traditional lighting fixtures such as incandescent lamps
In order to accelerate the promotion of energy-saving light sources, in December 2008, the EU adopted the decision to phase out high-power ordinary lighting incandescent lamps: ordinary lighting incandescent lamps of more than 100 watts exited the market in September 2009; general lighting above 40 watts Incandescent lamps will be withdrawn from the market in early 2010; after 2012, all ordinary lighting incandescent lamps will be replaced by energy-saving lighting fixtures, and ordinary lighting incandescent lamps will no longer be sold; tungsten halogen lamps will also be banned from sales in 2016. Australia (2010), Canada (2012), and the United States (2014) also responded to changes in the lighting industry in the form of "incandescent bans" for a certain period of time, or the abolition of ordinary lighting incandescent lamps and tungsten halogen lamps.
3 Introduce the policy of demonstration application and promotion
The US Department of Energy (DOE) has incorporated semiconductor lighting into the Energy Star program, and in 2009 began implementing energy-saving subsidies to promote LEDs to replace neon-based billboards ($2 billion market). The latest US economic revitalization plan has funded the LED application programs of major city governments. The transformation and development of the energy industry is the core of the Obama administration's economic recovery plan. In February 2009, the former US President Bill Clintonâ€™s foundation began to promote 15,000 LED street lights in Los Angeles. The goal is to replace 140,000 traditional street lights in Los Angeles in five years, saving 40%. In addition, cities such as Oakland, San Francisco, Pittsburgh and San Jose, as well as the US Department of Defense Pentagon, are also demonstrating applications for road lighting and interior lighting. In December 2005, Japan introduced a tax law to improve and improve energy use. It stipulates that enterprises or institutions use LED lighting devices to replace incandescent lighting devices between 2006 and 2007, and can obtain 130% excess depreciation of investment, or a tax rate of 7% of investment. Relief to expand the domestic LED lighting needs. Recently, Japan has actively introduced LED lighting applications at various levels of life. South Korea proposed the â€œ15/30 Planâ€ in early 2009, and it is expected that 30% of the lighting will be replaced by LED lighting by 2015.
