these streetlights are great for the planet — but horrible for your health - solar powered street lights

On both sides of the street, the school is good, the road is quiet
Strong street light. . .
The last one may not appear on your list of finding the last home, apartment or apartment, but the doctor now says it should probably have.
Even if they save energy, some lightLEDs (or LED)
The street light is too bright to actually endanger your health and safety, according to the advice of the American Medical Association, the largest medical association in the United StatesS.
The benefits of LED lights include a lot of energy and cost savings.
They consume 50% less energy than traditional lights.
The life of the LED light is two to four times that of the old LED light
LED lights, which means that maintenance costs are lower when the city goes out and needs to replace street bulbs.
But the bottom line for AMA is,
The intensity of sending out too much blue light LED street lights can actually throw away the sleep patterns of people living in these neighborhoods and make night glare on roads worse than traditional lights.
"Despite the benefits of energy efficiency, some LED lights are harmful when used as street lights," Maya.
AMA board member Babu said in a press release.
According to the press office, none of the authors suggested by AMA answered questions about the subject.
Brooklyn resident Jolanta benalle told the New York Times last year that he complained about the bright LED street lights near the Windsor Terrace.
New York City is spending $75 million to transform more than 250,000 street lamps into energy --
High-efficiency LEDs, according to The Times.
New lights are expected to save the city $6 million in energy costs and $8 million in maintenance costs each year.
But a lamp like this could also cost residents like Benal a lot of sleep.
According to a spokesman for the city's Transportation Department, the renovated street lights are designed to prevent glare.
However, at present, the blue light allowance for new street lamps is higher than what AMA suggested.
"The problem is that if people are not exposed to the dark at night, then they have problems sleeping," said Morris ohyne, director of Stanford's Sleep Epidemiology Research Center, telling Huffington Post
Ohayon and his colleagues recently studied sleep habits and quality of sleep for more than 15,800 people.
They found that people exposed to more nighttime light were almost twice as likely to be unhappy with sleep as people living in areas with insufficient light.
Those exposed to more light at night also reported that sleeping less at night and getting more tired during the day.
When it happens over and over again exposed to light, our circadian rhythm (
Clock inside the body)get disrupted.
In addition to affecting sleep, disordered circadian rhythms are associated with increased incidence of chronic diseases such as obesity, heart disease, depression, and some cancers.
Just like the blue light on a smartphone or computer screen inhibits the production of melatonin in the brain (
Body signal during sleep)
Neurologist and sleep expert Clete Kushida at Stanford Sleep Medicine Center explained in the aKBCW video that blue light in the led caused trouble.
Architect and city designer Stephen Quick told Huffington Post that there is actually no "white" LED light.
Quickly said that it looks like the white LED light used in street lamps is made up of amber, red, green and blue, an associate professor of architecture at Carnegie Mellon University, did not participate in writing suggestions for AMA.
Quick and his colleagues went deep into the cost-
Save the benefits of LED lights and potential health, safety and aesthetic issues for a report in Pittsburgh city in 2011.
The report was used to help Pittsburgh complete its plan to replace 40,000 street lamps.
Fast says the study, like the new AMA proposal, suggests mixing neutral light with blue and other colors for street lights.
"Think about incandescent lamps ---
Neither warm nor cool [in color].
It's soft, but it doesn't have the cool qualities you see in fluorescent.
The Pittsburgh report's proposal does allow a little more blue light than AMA, Quick said.
Another potential problem with the LED street light being too bright, as suggested by AMA, is glare.
"Many people think that the brighter the light, the safer it will be . "
But the LED lights are oriented. -
This means that it will be launched in a specific direction, unlike conventional bulbs that emit light and heat in all directions.
Fast says that because the light does not spread, the led creates a "glare zone" for the driver at some angles, which may be worse than a traditional street light.
The new AMA recommends encouraging "proper design, shielding and installation" to help reduce glare.
Fast also says dimming the lights helps reduce glare.
"The higher the intensity, the more glare is coming out of bounce light or direct light," he said . ".
"When the light continues to decrease, we don't have glare problems when the light is really bright.
"AMA's new proposal may require some reflection on current green building standards and projects. The U. S.
Committee on green building-
LEED is the most widely used green building certification project in the world ---
LEED website technical expert Theresa Backhaus told Huffington Post by email that a specific type of street light is not supported.
"We encourage lighting design to take into account the health, safety and welfare of people and the environment," she said . ".
She said that USGBC's light pollution reduction credit was established to reduce the harmful effects of light pollution.
The credit rating that construction and development projects can achieve is one of the four levels of LEED.
The credit requires the project to use a lower level of lighting for "sensitive areas" (such as residential areas and nature reserves), but does not specify a limit on the number of blue light available.
The good news, Fast says, is that most LEDs, especially the newer ones, are made with dimming controls-
Therefore, the intensity of the light can be easily adjusted.
Changing the color balance of the lights can be much more difficult.
Sometimes it is possible to replace only the LED itself, but sometimes the entire fixture needs to be replaced, Quick said.
"And the cost is high.
"Take-out is that there is nothing bad about the LED lights themselves.
"We save a lot of energy by using them.
We also save a lot of money on maintenance costs . "
But the right color and intensity are important.
"The best procedure right now is for cities to be cautious and know what they are buying," he added . ".
