Why does the led light look so uncomfortable?

At night, when an electric car or car drove from the opposite side, the headlights were dazzling and headache. Except for the white and bright lights, everything else is black and dull, and nothing can be seen. This kind of light is an LED light. There are also street lights on the highway. Most of them are halogen lights now, and they consume so much power. Why not replace them with LED lights? That was because I was afraid of a car accident. Because halogen lamps are the closest to the sunlight, and people are the most adaptable to sunlight, after all, people have been growing up under the sun. So why does LED look so uncomfortable? 1. LED lights are very dazzling. Because the light-emitting area of u200bu200bthe LED lamp is small and the distribution is too concentrated, it is a spotlight type. When used for lighting purposes, if you do not use suitable lamps and disperse the light source, it will feel very dazzling! 2. The blue light of the LED light. Because the blue light emitted by the LED lamp beads has a strong light direction and a small light-emitting area, it will hurt the eyes if you look directly. Therefore, LED lights need to be used after the light distribution treatment of the lamp. The effect of blue light on nerves and sleep disorders is well known. All LEDs emit blue light, which can be adjusted to other light colors by passing through the phosphor coating. It’s like a blue flashlight, so if the LED wants to be brighter, it can only emit more blue light. Studies have even proved that blue clothes will hues faster under LED.

The LED light has a narrow spectrum. 'LED lighting is not so comfortable' is the reason why the spectrum is very narrow. As a result of human evolution, the most suitable light at this stage is sunlight. In contrast, in the visible light wavelength range, the spectrograms of different lamps are as above. It can be seen that the spectrum of the LED is discontinuous, and the energy distribution in the entire visible light wavelength range is uneven, which makes it look uncomfortable.
