LED street lights need to be used with caution

In June, the American Medical Association warned that high-intensity LED street lights in Seattle, Los Angeles, and New York would release invisible blue light and interfere with sleep rhythms, the Washington Post reported on Sept. 25. May also increase the risk of cancer and cardiovascular disease. Medical Association also reminded that, LED driver's night driving vision. The American Medical Association urges states and cities to reevaluate the strength of existing LED street lights.

2015 US Department of Energy report that about 13% of the area or road using LED lighting. LED energy than the yellow high-pressure sodium lamp at least 50%, can last 15 to 20 years. And high-pressure sodium lamp, LED light uniform.

City managers believe that these concerns about health concerns are not sufficient. The first generation of LED street lights benefit the whole city is a fact. New York responded to complaints from residents and promised to replace the high-intensity LED bulbs. Medical Association believes that low-intensity white LED bulbs are safe.

Seattle City Lighting spokesman Scott Thomson, who oversees outdoor lighting in Seattle, dismissed the claims that high-brightness, white LED street lights affect health, noting that streetlights release less blue light than computers and televisions.

After a year and a half of discussion and sampling, Lake Worth, Florida, replaced the sodium lamp with 4150 amber LED street lights. "We found the importance of color to the city and made this choice, and we are proud of it," said Michael Bonn, the city manager.

Mark Hartman, Phoenix's chief sustainability officer, says the city's crossroads and stadiums require dense, bright lighting, and residential lighting is relatively soft. He said the city will consider the health of residents. "Although Blu-ray affects sleep, but no one so 9:00 do not watch TV, do not have a computer." He said.

Lighting Research Center at Rensselaer Polytechnic Institute in Troy, New York, states that the dangers posed by lighting are far less severe. Research Center pointed out that the report of the American Medical Association premise is long-term stay in high-intensity LED street lights, rich in blue LED is dangerous. But for the vast majority of people, the normal use of lighting equipment without any problems.
