LED Solar Street Lights

LED lights are rapidly becoming the standard lighting technology in many applications, and in many areas. Basically, all in one solar street lights and other solar led lights have also become one of the best options to get the light, as incandescent and CFL lighting options are phased out.

LEDs are of course energy efficient, last many times longer and are therefore preferable from an environmental standpoint, however, not much is mentioned with respect to the human and consumer side of things — especially when it comes to the safety and health effects of the emitted light itself.

Electrical and toxicity concerns of LEDs are generally in line or superior when compared to incandescent and fluorescent lamps. Most governmental authorities have continued to adapt existing building and safety codes to prevent fire and electric shock risks — and of course, it is always a smart idea to practice basic electrical safety.

Led Street Light Bulbs

LED bulbs do not emit any ultraviolet light, but in recent years, “blue light” has been one of the most commonly discussed dangers and risks that surround LED lights and display screens that use LED backlights (smartphones, tablets, TVs, etc).

Blue light is known to stimulate the production a melanopsin, a hormone in our eyes that promotes alertness. Natural daylight has plentiful blue light content, and it is thought that melanopsin helps us regulate our circadian rhythms as the day breaks and exposure to natural daylight begins.

LED lights and our devices do contain a significant amount of blue light, and the concern is that excessive use during evening hours will cause our bodies to continue the production of melanopsin, making it harder to fall asleep naturally.

During evening hours, our bodies’ natural expectation is for blue light exposure to be diminishing, but by continuing to use LED devices rich in blue light, we are altering the natural biological clock in our bodies.

When it comes to choosing the right type of LED bulb for use during evening hours, you may want to look for a light bulb designed for circadian health in mind.

In general, you will want to look for bulbs that provide more red energy, and less blue energy, in their respective light spectra. Red energy (long wavelength) is plentiful in light given off by candles and flames — types of “light” that our bodies are already accustomed to being exposed to at night, and does not impact circadian rhythms.

So, is the blue light in LED lamps harmful to your health and do they present a safety risk? Yes — they certainly do — but the risks and concerns are specific to overexposure to blue light during evening hours, and can be effectively managed and controlled. By paying attention to the LED bulb specifications, and taking appropriate precautions, you can safely incorporate LED lights in your home without any negative health effects of the “blue light hazard.”

Despite all of the buzz around blue light being a hazard, it is important to remember that the health risks of blue light are very specific to overexposure during evening hours.

In fact, blue light is an essential part of our circadian rhythms, as exposure during the morning and daylight hours provides an indication to our bodies that it is daytime and time for us to be alert.

The best way to maintain regular, healthy and appropriate exposure to blue light is to utilize natural daylight as much as is possible.

Preliminary research indicates that a lack of exposure to blue light can have detrimental health effects. Health conditions such as SAD (Seasonal Affective Disorder) have been suggested to be caused by a lack of exposure to natural light, especially common during winter months.

LEDs and how all in one solar street lights and 3 panel solar lights are a new and exciting lighting technology, but they are not without health and safety risks. By being aware of the spectral content as well as the flicker metrics, you can be sure to minimize the risks of LED lighting on your health and well-being.

Summary

LED Led solar street lights are now being considered as the best alternative source of energy to meet the lighting needs of the streets, but there is certain concern about its health issue. The above article describes the impact of the solar lights on health and remedy to reduce the impact.
