A 1.2-meter-long LED tube has a retail price of nearly 200 yuan. Even if people know that it is energy-saving, environmentally friendly, and has a longer service life, most of them will choose traditional fluorescent tubes that sell for less than 10 yuan. Recently, at the branch of the Lighting Society of the 8th Youth Academic Annual Meeting in Nanjing, relevant experts broke the biggest bottleneck that restricted LEDs from entering the homes of ordinary people. Experts analyze that with the maturity of technology, the cost of LED lighting fixtures will continue to decrease within three to five years, reaching the civilian price acceptable to ordinary consumers, and truly achieving popularity in the home field.
Shen Ru, secretary-general of the Nanjing Lighting Society, said that LED lights have 80% better performance than energy-saving lamps. For example, a household 5-watt LED bulb can replace an 11-watt energy-saving lamp. The lighting effect of the LED street light is equivalent to a 250 watt high pressure sodium lamp. Moreover, LED lights are completely free of mercury pollution and do not contaminate soil and groundwater.
Today, low-carbon technology has been greatly promoted, LED lighting has been increasingly used in construction, landscape and municipal engineering, but there is still a considerable distance from ordinary home users. Shen Ru said that the reason is because the core technology of LED is in the hands of foreigners, and the price of domestic LED products remains high. In addition, domestic LED manufacturers mainly aim at market areas such as architectural landscape lighting, large-screen display, traffic signal lights, etc., and are insufficiently developed for ordinary people.
Zhou Ye, general manager of Jiangsu Branch of Zhen Mingli Holdings Co., Ltd., who has been engaged in LED lighting research and development for a long time, told reporters that 3 years ago, the 40-watt LED tube factory price was about 300 yuan, and most of the products are now sold at 140,160 yuan. . Although most of the LED core technologies and patents are currently in the hands of foreign companies, domestic companies have not given up on research in this area, and have achieved some results in recent years. Before 2002, domestic LED chips were completely dependent on imports. In 2006, the localization rate reached 44%. He is very optimistic that the survey shows that the price of ordinary household LED lights will be reduced to 4,060 yuan, consumers can accept, by then, LED green lighting will truly replace energy-saving lamps, into every household.
