Ultraviolet light is a kind of light wave that is invisible to the naked eye. It exists on the outside of the ultraviolet end of the spectrum, so it is called ultraviolet light. It is a kind of light wave, according to different wavelength ranges, it is divided into four different wavebands: A, B, C, D. The ultraviolet wavelength of UVA lamp is between 320～420nm, and its center value is 365nm. It is commonly used in industrial glue. Curing, tungsten ore identification, fluorescence detection, biopolymerization, oil pollution detection, ore prospecting, criminal detective, textile industry, archeology, health, stage, nightclub, theater and signal lighting. UVB tube, wavelength 275～320nm, also known as medium wave erythema effect ultraviolet rays, mainly used in health, aging test, spectrum analysis, etc. UVB ultraviolet rays have erythema effect on the human body and can promote the metabolism of minerals and the formation of vitamin D in the body. However, long-term or excessive exposure will tan the appearance and cause redness, swelling and peeling. The phototherapy tube for external diseases, the ultraviolet light to keep healthy, and the plant growth light are made of special transparent violet glass (not transmitting light below 254nm) and phosphor with a peak near 300nm. UVC lamp tube, wavelength 200 ~ 275nm, also known as short-wave sterilization ultraviolet. It is very close to the peak wavelength (265nm) of the bactericidal efficiency curve, so when the 253.7nm radiation reaches a certain value, it can kill intestinal bacteria, Aspergillus flavus and HBsAg (hepatitis B surface antigen) in a short time. Extinct. The ultraviolet germicidal lamp emits short-wave UVC ultraviolet rays.uvc lamp air purifier,uvc lamp for home,what is a uvc lamp,uvc lamp bulb,ultraviolet b lamp,ultraviolet c lamp,uvc lamp diy,uvc lamp e27,uvc lamp kit
