Ultraviyole uch xil diapazonga ega, UVA/UVB/UVC va asosiy ilovalar har xil.
UVA band: wavelength 320-420nm, also known as long-wave dark spot effect ultraviolet. It has strong penetrating power and can penetrate most transparent glass and plastics. More than 98 percent of the long-wave ultraviolet rays contained in sunlight can penetrate the ozone layer and cloud layer to reach the earth's surface. UVA can reach the dermis layer of the skin, destroy elastic fibers and collagen fibers, and tan our skin. The UVA ultraviolet rays with wavelength of 360nm are in line with the phototaxis response curve of insects, and can be used to make trap lights. UVA ultraviolet rays with wavelengths of 300-420nm can pass through special colored glass lamps that completely cut off visible light, and only radiate ultraviolet light centered at 365nm. Shenzhen Yinghong is used to make non-destructive flaw detection lamps, fluorescent leak detection lamps, degreasing cleaning lamps, Criminal police forensic inspection lights, laboratory inspection lights, etc. In addition, this ultraviolet light can also be used for ore identification, anti-counterfeiting verification, banknote inspection, curing, security inspection...
UVB band: wavelength 275 320nm, also known as medium wave erythema effect ultraviolet. Medium penetrating power, its shorter wavelength part will be absorbed by transparent glass, most of the medium-wave ultraviolet rays contained in sunlight are absorbed by the ozone layer, and only less than 2 percent can reach the earth's surface, which is especially strong in summer and afternoon. UVB ultraviolet rays have an erythematous effect on the human body, which can promote the metabolism of minerals and the formation of vitamin D in the body, but long-term or excessive exposure will tan the skin and cause redness and peeling. Ultraviolet health lamps and plant growth lamps are made of special transparent violet glass (which does not transmit light below 254nm) and phosphors with a peak value around 300nm.
UVA ultrabinafsha nuri asosan ob'ekt yuzasining qarishi va sarg'ishini tekshirish va hayvonlar va o'simliklarning o'sishini rag'batlantirish uchun ishlatiladi. Yorug'lik manbalari sifatida o'rta{0}}bosimli simob lampalari yoki maxsus fosforli past{1}}bosimli simob lampalaridan foydalanish mumkin. Tor{2}}spektrli UVB inson teri kasalliklarini, masalan, vitiligo, psoriaz va hokazolarni davolashda ham foydalanish mumkin.
UVC diapazoni: to'lqin uzunligi 200 275 nm, qisqa{1}}to'lqinli sterilizatsiya ultrabinafsha deb ham ataladi. U eng zaif penetratsion qobiliyatga ega va ko'pchilik shaffof shisha va plastmassalarga kira olmaydi. Quyosh nurlari tarkibidagi qisqa{2}}to'lqinli ultrabinafsha nurlar ozon qatlami tomonidan deyarli to'liq so'riladi. Qisqa{3}}to'lqinli ultrabinafsha nurlar inson tanasi uchun juda zararli. Qisqa muddatli{4}}ta'sir qilish terini kuydirishi mumkin. Uzoq{5}}muddatli yoki yuqori{6}}ta'sir qilish ham teri saratoniga olib kelishi mumkin.
UVC ultrabinafsha nurlari kuchli sterilizatsiya qobiliyatiga ega va ultrabinafsha mikroblarga qarshi lampalar sifatida ishlatilishi mumkin. Printsip shundaki, C-to'lqinli ultrabinafsha nurlar bakteriyalar va viruslar kabi mikroorganizmlarning DNK aloqalarini uzib, ularning ko'payish va bakteritsid ta'sirini yo'qotishiga olib kelishi mumkin. Uning samaradorligi 264 nm da cho'qqisiga etadi, bu past bosimli UV lampalar chiqaradigan spektral cho'qqi-ga juda yaqin. Shuning uchun past bosimli simob lampalar ko'pincha sirtlarni dezinfektsiyalash kerak bo'lgan joylarda ishlatiladi.
UVC diapazonidagi ultrabinafsha nurlar, shuningdek, makromolekulalarning organik moddalarini suv va karbonat angidridga parchalash uchun katalizator moddasi bilan birgalikda fotokatalizator materialining yuzasida ham harakat qilishi mumkin. Ushbu turdagi samaradorlik endi mikroelektronika sanoatida engil tozalash, atrof-muhitni muhofaza qilish sanoatida organik chiqindi gazlarning degradatsiyasi va maishiy texnika sanoatida ichki havoni tozalashda tobora ko'proq qo'llanilayapti. U samarali, ekologik toza, energiyani tejovchi{0}}va ifloslanishni ikkilamchi tozalash usuli ekanligi isbotlangan.
