The report of the American medical Association (AMA), entitled "Light Emitting Diode Lighting Community" was unanimously approved by representatives of all members of the Association the issues raised by the International Association of Dark-Sky for more than five years ago. The report presents the significant effects of the transition as outdoor lighting to LEDs.
The AMA supports the use of led lighting to reduce energy consumption and use of fossil fuels, but recognizes that some led lamps are harmful.
The report describes in detail the results and scientific evidence that the use of blue white light at night increases the risk of cancer, diabetes and cardiovascular diseases.
Moreover, according to the report, blue-and-white street LED lighting is five times more destructive to our cycle of sleep and wakefulness than normal street lighting, and recent large studies have documented that the bright lights of a residential area associated with reduced sleep, impaired functioning during the daytime and an increase in cases of obesity.
The result is a potential health risk to the population from excessive exposure to blue light in the report, the AMA encouraged attention to optimal design engineering functions during the transition from current lighting technology to led. These include requirements for proper shielding of outdoor lighting, subject to adaptive management, which can make lighting dim or low at night, limiting the appropriate color temperature of the external light 3000 Kelvin or below. Color temperature is a measure of the spectral composition of light, and higher values indicate a greater amount of emitted blue light.
The results of the report also underline the fact that the harmful effects of an intense blue LED lighting not only affect people. Other organisms equally vulnerable to violation of their life's rhythms as people, and often even more. These effects can be reduced by limiting emissions of blue light. Policy makers, officials and the public, and now the science insist that the led systems were designed to reduce impacts on wildlife and human health.
