LED street lights of high intensity may affect people’s sleep. Because of the blue light LED street lights contain, they will inhibit the production of melatonin, thus violating people’s circadian rhythm.

The solutions include reducing the brightness, changing the color temperature to warm white light, etc. If the light is set suitably, the effect can be reduced to the minimum.
