Replace traditional street lights within 5-10 years
Since April 28 this year, the Ministry of Science and Technology has launched the pilot project of "Ten Cities and Ten Thousands" semiconductor lighting application projects in 21 cities in 16 municipalities. At present, LED lights in many cities are used in landscapes, tunnels, and street lights. On the Zhongshan Road, which has just been completed in Nanjing, all the landscape lights are also used LEDs. Industry insiders predict that in the near future, all illuminators with bright light will be replaced by LEDs.
"In terms of street lamps, LEDs are replacing traditional street lamps. It is an irresistible trend. It is estimated that it will take another 5-10 years." Experts say that street lamps are an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps and high-pressure sodium lamps. The shortcomings of low overall light efficiency have caused a huge waste of energy. According to reports, high-voltage nano-lighting requires fixture support, and because the light of the high-pressure nano-light is illuminated to the surroundings, about 40% of the light will be blocked by the luminaire. The LED has no light diffusion, and the illumination efficiency is 80%-85% higher than that of the high pressure nano lamp. Some people have done calculations. The energy-saving effect of high-power LED street lamps is remarkable. Instead of high-pressure sodium lamps, it can save more than 60%. The reporter also learned that at present, there are 100 LED street lights installed in Longchi Lake, Liuhe, Nanjing, and the effect is very good.
The price is expensive but value for money
Many citizens use LED lighting to "respect" to its higher price. In the forum, many people in the industry believe that the reason why it is expensive is because LED LED chips are very expensive. "With a watt of white LED chips, the market has to sell for 20 yuan." Experts say that many large companies are currently developing new chips, and LED prices are expected to decline in a few years.
"In fact, in some specific occasions, even if LED lighting is used now, it is more cost-effective than using ordinary lamps." The expert gave reporters an example: in hotels and galleries, there are always multiple spotlights on the wall, they usually It doesn't matter for a long time. Nowadays, the spotlights are commonly used in halogen lamps, which have ultraviolet rays that cause fading in the place where they are illuminated. Infrared rays in the lamps can cause dehydration. So the value is not high. "But LEDs don't have ultraviolet and infrared rays, they are very healthy and harmless to the objects being illuminated." Experts say, more importantly, the high energy efficiency and longevity of LEDs. "In general, a 3 watt LED lamp with a price of around 100 yuan is enough. With it, the electricity cost saved in two months has reached more than 100 yuan, and the rest of the money is all the profits you earned."
Real LED TV is not yet available
Super energy-saving, colorful &hel lip;... Recently, all major brands have pushed LED TVs, claiming to be a new generation of high-definition TV products. Yesterday, at the 2009 LED Technology Development and Application Session of the Nanjing Science and Technology Annual Conference, Dr. Yang Haifeng, a famous semiconductor lighting expert, pointed out that the hot-selling "LED TV" is actually just a liquid crystal TV using LED backlight technology, not a real LED. TV. According to reports, the LED TVs currently on the market are not TVs that use LED screens, but only the backlights of LCD TVs are replaced by fluorescent tubes. The current LED TVs should be accurately LED backlight LCD TVs. . In the true sense of LED TV, it should be a TV with LED panels. According to reports, compared to ordinary LCD TVs, LED LCD TVs certainly have their advantages, such as long life and brightness of the backlight, but it does not mean that the latter must be stronger in terms of image quality and panel. According to reports, the true meaning of LED TV should be the use of LED panels, LEDs used as lighting units to display color images. Yang Haifeng said that the production technology of LED panels is far from mature, mainly due to insufficient resolution. Home LED TV products are still under research and development, and have not yet been listed.
