LED technology has been mature enough to generate super bright light

Li Shuzhi comes from  the Shanghai Research Center of Engineering and Technology for Solid-State Lighting ,said the center started research on led linear high bay light boards when more commercial LED boards were installed in the city in 2008. He said there are at least 1,000 LED boards in Shanghai and there are over 100 such boards along downtown Huaihai Road.

In his opioion, LED technology has been mature enough to generate super bright light. Advertisers prefer brighter boards to be seen far away, while the key is how to properly use it. He suggested LED boards must consider visible angle and brightness to reduce glare.

According to doctors, people's eyes will be harmed by prolonged viewing of LED boards. As a result, Professionals suggested the brightness of LED boards should be reduced by two thirds at night and that limits should be imposed on how long the boards are on at night.Beijing has carried out a law in 2008 mandated the position of electronic boards, brightness at night and daytime brightness based on sunlight intensity.

 Reportedly,Taiwan Unity Opto Technology has received a great deal of around US$9 million orders from several European lighting heavyweights for its led high bay light lamps. Its revenue for this year is likely to double from last year to NT$3 billion.

Stephan Wittekind, Business Development Director at Traxon, said, “The highlight of this concept is that the fixtures are completely integrated into the semi-transparent structure. Therefore, they are not visible during the day, and the appearance of the stadium is completely different by night.” According to The Yomiuri Shimbun, Japanese government has encouraged major electronics retailers and home appliance makers to voluntarily halt production and sales of incandescent bulbs to save Led linear high bay light power this summer. The government plans to submit a written request under the names of Economy, Trade and Industry Minister Yukio Edano and Environment Minister Goshi Hosono to an industry group, probably sometime this week. The industry side has indicated it will oblige. It is extremely rare for the government to ask retailers and manufacturers to refrain voluntarily from selling and producing specific products.The two ministers plan to send their request to Sho-ene Akar...
