In the face of international energy shortages, high oil prices and the importance of national policies, the speculation of energy-saving and emission reduction concept stocks has continued to heat up. It is particularly noteworthy that the LED semiconductor lighting concept stocks with energy-saving and environmental protection concepts have once again become prominent after people have forgotten them for a long time. Among them, Fangda a (000055) has announced two consecutive daily limit for the news that the subordinate enterprises have passed the research on the key manufacturing technology research and application demonstration project of LED fluorescent lamps for energy saving and emission reduction and renewable energy major projects in Guangdong Province. Xiamen Xinda (000701) also showed its strong explosive power in the short-term due to its LED concept of a very competitive LED chip manufacturing company, which is 10% owned by Sanan Electronics. Why is the LED that has been forgotten for a long time? The concept stocks are getting angry again?
Because of lack of resources and energy shortages, it has become a bottleneck for global economic development. Against the background of increasingly tight power supply, countries around the world have begun to explore new energy-saving lighting sources. White LED is the most promising LED emerging product, because according to research, LED as a light source has three advantages of energy saving, environmental protection and long life. In theory, it can realize only 10% of the energy consumption of incandescent lamps, and 50 energy saving than fluorescent lamps. %. It is packaged in a solid package and has a lifetime 10 times that of a fluorescent lamp and 100 times that of an incandescent lamp. For example, incandescent lamps consume 100 degrees of light, and semiconductor lighting requires only 15 degrees. Therefore, semiconductor lighting is known as the lighting revolution of the 21st century. Coupled with the recent madness in oil prices, on the 1st of this month, at the working meeting of the Premier of the State Council and the Leading Group for Energy Conservation and Emission Reduction of the State Council, energy conservation and emission reduction have once again received unprecedented attention from the state.
Now, a semiconductor home lighting is 200-300 yuan. It is expected that the price will drop sharply after the popularity in 2008. At the same time, the LED light source has no ultraviolet light, infrared light and the like, and can avoid the secondary pollution of the fluorescent tube rupture and overflow of mercury. An American expert has pointed out that LED semiconductors have completed a revolution in electronics, and the second revolution will be carried out in the field of lighting. As a result, a wave of LED lighting swept the world, setting off a second revolution in the lighting industry. More experts believe that high-brightness LEDs will be one of the greatest inventions after humans invented incandescent bulbs.
