The Science Association Annual Meeting in Nanjing in 22th 2009 “on the the venue of LED technology development and application” Nanjing Illuminating Engineering Society said, with technology development, LED (light-emitting diode (LED) lighting) lighting will is the trend of the times by is used as a lights,but due to the relatively high prices, is still a long way to go in the future.
replace traditional street lights within 5-10 years
Starting from 28th April this year, the Ministry of Science and Technology start a “Ten City, ten thousand” semiconductor lighting application engineering pilot launched in 21 cities in 16 provinces,municipalities directly under the Central Government. Green led lights in many cities have applications in the landscape, tunnel, street lamps. Nanjing has just completed Zhongshan East Road , all use LEDs too. Insiders predict: in the near future, Where there are light emitters will be LED to replace.
“For example the street lights, LED instead of the present traditional street lights, is a kind of trend, it is estimated that another 5 to 10 years can make .” Experts say, the street light is an important part of the lighting of the city lighting, and the traditional high pressure sodium lights often used high-voltage sodium lamps. The low efficiency shortcomings of the overall glazing caused a huge waste of energy. According to reports, high-voltage sodium lamps lighting lamps need the support of lighting. And because the high voltage sodium lamp light is irradiated to the surrounding
, about 40% of the light will be obscured by the lighting. The Green led lights don’t have diffuse of light .Light efficiency is higher 80% to 85% than high-voltage sodium lamps.Once measurements are done by someone.And it is significant energy saving effect of high-power LED street light.Instead of high-voltage sodium lamps can save more than 60% . The reporter also learned that currently in Luhe longchi Lake , the effect is very good about 100 LED street lights installed.
The genuine LED TV don’t appear on the market yet
The ultra-thin, energy-saving, colorful … Recently, major appliance brands have been pushing LED TV, claiming to be a new generation of high-definition television products. the venue LED technology development and application in Nanjing Science and Technology Annual Meeting of 22th 2009. According to reports, the real LED TVs use LED panel as a light-emitting unit with LED to display the color screen. Yang Haifeng said, the LED panel production technology is far from mature ,mainly the resolution isn’t enough. Household LED TV products is still in development and don’t appear on the market yet .
