I was told that because LED lamps operate on the same principle as LASERs, they are dangerous. It is true?"
The working principle of an LED has little in common with the LASER, its light being neither coherent nor concentrated. Thus, the luminous energy of the LED is the same as that of an ordinary lamp, only with the difference that it is monochromatic, that is, it emits light of only one color. Thus, the combination of 3 LEDs gives the white light that has no hazardous components neither the salute nor the vision.
