Semiconductor Lighting Will Become Mainstream of Low Carbon Lighting

21 Jul

Against the background of global warming, low power consumption, low pollution based “low carbon economy” became the world’s hot spots. American and European countries vigorously promote “low-carbon revolution” with high energy efficiency and low emission as the core, focusing on development of “low-carbon technologies”, and make major adjustment to industry, energy, technology, trade and other policies to seize opportunities and the commanding height of industry. The essence of low-carbon economy is high efficient utilization of energy, research and development of clean energy, the pursuit of green GDP, the core of low-carbon economy is energy technologies and emission reduction technology innovation, industrial structure and system innovation and fundamental shift of human existence and development concept.

Building low-carbon city, we need to speed up developing the cluster economy as core to promote industrial structure innovation; developing recycling economy as core to promote energy saving and emission reduction innovation. Developing low-carbon economy is a choice of economy development model, which means energy structure adjustment, industrial structure adjustment and technological innovation, low-carbon economy is an important way for China to develop sustainably.

Developing low-carbon economy is the embodiment of China’s responsibility as “citizen of the world”, is also the rare opportunity for China to achieve sustainable development and change economy developing model. Implementation of low-carbon economy requires government leadership, including the drafting long-term strategy, issuing policies to encourage technological innovation, energy saving and emission reduction, utilization of renewable energy, reducing and exempting tax, financial subsidies, government procurement, green credits and other measures, to lead and boost the development of low-carbon economy; but also requires enterprises to recognize the direction and follow consciously, and promote the “collective action” of low carbon economy development. Only when more enterprises change the current passive state and consciously follow the pace of low-carbon economy, will China has realistic basis and future hope to shift to low carbon economy.

Oil and coal reserve and production can not meet the demand of economy development. Endured over 10 years overdraw of rapid economy development, China’s energy crisis has become increasingly prominent, energy shortage has become a bottleneck restricting economy development. As the lifeline of modern industry, commerce and civilian use in recent years, frequent “electricity shortage” has caused huge economic losses.

In the situation of energy shortage, as one of the big power consumers, lighting power consumption became social focus, and as important parts of lighting industry, road and landscape lighting power consumption accounts for about 45~60% of the total lighting consumption, whose status is really important. Therefore, to ease the overall shortage of national electricity and reduce energy consumption, promoting energy saving projects in main lighting areas will affect the general situation of energy saving and consumption reduction.

Low-carbon economy: the shift that China must achieve

It has been 30 years since the first time determination that climate change was a global problem, carbon dioxide emission has not been effectively resolved. In recent years, China’s carbon dioxide emission has increased rapidly, which surpassed the United States in 2008 and China became the world’s largest emitter of carbon. In a short term, the events and policies such as “proposed clean energy and security case” of the United States has been passed in the Senate, Obama will visit to China in November, Copenhagen Conference will be held in December, China’s new energy development plan may be introduced during the year and so on have urged low-carbon economy to become the hot spot at end of 2009. In a long term, since 2009, the United States has repeatedly publicly requsted to add developing countries into the system of emission reduction, which directly pointed to China, the emission reduction pressure for China is increasing day by day; In China, the establishment of market-based emission reduction system is just a matter of time, Currently, China’s rapid economy recovery provides a good opportunity for low-carbon economy development.

Energy-efficient lighting: met an opportunity of rapid development

Incandescent Power consumption accounting for about 7% of total global electricity consumption, and accounts for 2% of the total emission of carbon dioxide. Since 2007, most countries have drafted policies and measures to promote the steps of energy-saving lamps replacing incandescent lamps, by 2012, almost all developed countries will ban incandescent lights. Since 2012, if the world will change all incandescent lamps into energy-saving lamps, 5.5% power per year will have been saved and about 5 million tons of carbon dioxide emission will have been reduced. Currently there are more than 15 billion incandescent lights in the world, application ratio of incandescent lamps to energy-saving lamps is about 4:1, the penetration rate of energy-saving lamps is low, and in China’s general lighting, the application ratio of incandescent lamps to energy-saving lamps is about 7.5:1, the space for energy saving lamps to replace incandescent lamps is huge. The government has already introduced matching subsidies policies to promote energy-saving lamps, meanwhile the 6 ministry including Development and Reform Commission jointly announced the “semiconductor lighting energy saving industry development views” last month, which pointed out that “by 2015, the output value of semiconductor lighting (LED) energy saving industry will have increased by 30% anually; market share will have increased year by year, functional lighting will reach about 20%, LCD backlight will reach 50%, and landscape decorations and other products will reach more than 70%,” and so on, the prospects of LED development is quite bright in the future.

LED light source has a long lifespan with various colors, it is energy saving and can be applied for a wide range. It is belived that in 2010 81% of notebook computers will use LED backlighting technology, LED products will also accelerate penetration into LCD TV and monitor areas. As the global consensus has been achieved to develop low carbon economy, LED industry with its performance advantage will meet opportunity for rapid development, LED lighting market will also increase explosively, and the market scale in 2012 is expected to reach 1.6 billion.
