Product Detail Description (1) 60 pcs UVC LED chip Per meter (2) Without lead, mercury and other heavy metals, RoHS certification, environmental protection; (3) Flexible PCB 3oz thickness (4) Genuine 3M tape or good heat dissipation function blue tape (5) DC12v input, easy to install and use, can directly replace traditional disinfection components; Ultraviolet energy is categorized by wavelength, and is broken down into the following types: UVC radiation, short-wave ultraviolet, it cannot reach the ground because it has been absorbed when passing through the ozone layer. UVB radiation, medium-wave ultraviolet rays, accounts for about 80% to 90%. It can reach the dermis layer, causing skin to be sunburned, causing skin peeling, erythema, tanning, etc., but it can be blocked by glass, umbrellas, clothes, etc. . UVA radiation, long-wave ultraviolet rays, accounts for about 10% to 20%. It is the most important factor in premature aging of the skin. It can penetrate the dermis, tan the skin, and cause damage to the skin and collagen, causing skin photoaging and even Skin cancer has a slow and long-lasting effect and is cumulative, so it is called "age ultraviolet rays" and is not blocked by windows, umbrellas, etc., even if it rains on a cloudy day. UV absorbed by ozone layer (1) Why Does it Have to be UV-C? The reason why the correct UV wavelength for sterilization applications is absolutely critical is the mechanism of pathogen inactivation. DNA and RNA are the foundation of life, including microscopic organisms and pathogens such as viruses, bacteria and molds. Without this genetic material, the pathogen will not be able to multiply and eventually cause the death of the infected colony. Attention! 1.
