Almost all display devices have problems with radiation and blue light. As a recognized eye protection device, projectors also have radiation and blue light, but the radiation and blue light of projectors are relatively less harmful. Let's explore whether projectors have radiation and blue light and what harm they are.
Projectors have radiation and blue light, that's for sure. No matter what device, it has a certain amount of radiation, the LED lamp inside the projector also has a certain amount of radiation. At the same time, the projector's internal optical machine has three light paths of RGB, as well as short-wave blue light. However, because the display technology adopts the principle of diffuse reflection imaging, the damage of blue light to the eyes has been reduced.
Radiation damage is mainly electromagnetic and light damage. All charged equipment will have certain electromagnetic radiation, electromagnetic radiation will affect the human nervous system, cardiovascular system, immune system, eyes and reproductive system. Long-term radiation can cause dizziness, fatigue, and decreased immunity.
However, the current projection equipment has certain environmental protection standards, and the radiation damage of the projector is actually not large.
Blue light damage is also classified as electromagnetic radiation damage. It is the most energetic light in visible light, and it is very stimulating to the human eye when viewed for a long time, resulting in decreased vision. The projector adopts the principle of diffuse reflection imaging, which avoids direct blue light and reduces damage to the eyes.
