[UV UV Harm] UVLED Will Cause Harm to the Human Body

It is an inevitable trend to replace UV mercury lamps in UVLED ultraviolet devices. Many people want to know if UVLED will cause harm to the human body? First figure out the classification of ultraviolet rays: UV-A (315-400 nanometer, also known as long-wave ultraviolet), UV-B (280-315 nanometer, also known as medium wave ultraviolet), UV-C (100-280 nanometer, also also, also It is called short -wave ultraviolet rays; secondly divided purple light and ultraviolet light. At present, purple light and ultraviolet light are often made in the market. In fact, it is two concepts. UV rays generally refer to less than 400nm. Of course Below, UV light is invisible, just like infrared, then purple light refers to 410nm or more, that is, purple light, visible, just like the usual white light, red light, etc. Now answer the question above, is UVLED harmful to the human body? The answer is no, but it is certain that it cannot be directly shot. Is UV light harmful? This should be answered separately. UV-B (280-315 nanometer, also known as medium wave ultraviolet), UV-C (100-280 nanometer, also known as short-wave ultraviolet rays, must be harmful, the sunlight contains these, it contains these, which contains these. Therefore, it is easy to hurt the skin when the sun is very strong, so the UV-B, UV-C reaching a certain amount will definitely hurt the body, so protective measures must be taken. As for UVA, less damage to the body, especially the wavelength of more than 360nm, human skin has a certain protective function, so it can be regarded as no harm to the human body. Of course still can't shoot directly. More information is welcome to log in
