Bright LED Lights Could Harm Human Health
Are bright LED lights harmful to our health? The American Medical Association (AMA) thinks so. The AMA has issued certain guidelines on the use of bright LED lights.
People these days prefer using LED lights as they are light on the pockets, save energy and comparatively longer lasting than their traditional counterparts. However, the AMA has pointed out some health hazards that could pose a risk to human health.
The guidelines state that the colour temperature of the LED street lightings should not be more than 3000 Kelvin. Colour temperature is a form of measure of the spectral content of the light from a particular source, the temperature shows the amount of green, blue, red and yellow content in the light. The more the colour temperature of the light is, the whiter or bluer the light appears.
Many of the streetlights in various cities of the UK, and United States have adapted blue LED street lighting including New York and Seattle. After the installation, there have been various complaints about the harshness and glare of these lights too.
The AMA said that these bright LED lights cause discomfort and glares and can cause pupillary constriction in the eyes of the nearby residents because of the high colour temperature.
According to a report, “Municipalities are replacing existing streetlights with efficient and long-lasting LEDs to save money on energy and maintenance. Although the streetlights are delivering these benefits, the AMA’s stance reflects how important proper design of new technologies is and the close connection between light and human health,” Fox61 reported.
According to an article published by PRNewswire, “The three-layered display includes 84 individually controllable LEDs per headlamp that vary light distribution depending on traffic, weather and road conditions. The integrated adaptive High Beam Assistant Plus allows more frequent use of the vehicle’s high beams, offering greater safety and comfort.”
