Lub ntsiab lus ntawm wavelength: Lub wavelength ntawm lub teeb hais txog qhov kev ncua deb uas lub teeb nthwv dej taug kev hauv lub sijhawm ntawm kev co. Ntawd yog, raws li kev nthuav tawm ntawm nthwv dej, qhov kev ncua deb ntawm ob lub ntsiab lus uas nyob ib sab uas cov theem ntawm kev co txawv ntawm 2π. Lub wavelength λ yog sib npaug rau cov khoom ntawm yoj tshaj tawm u thiab lub sij hawm T, uas yog, λ=uT. Cov nthwv dej ntawm tib zaus tshaj tawm ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov xov xwm sib txawv, yog li cov wavelengths kuj txawv.
UV LED yog ib hom LED, nws yog ib lub teeb pom kev tsis pom, lub wavelength feem ntau qis dua 410nm. Cov feem ntau yog 365nm, 380, 395nm, 410nm.
Daim ntawv thov ntawm UV LED wavelength:
UV kua nplaum kho feem ntau siv lub wavelength ntawm 365nm, thiab UV inks, UV inks, thiab UV xim feem ntau siv lub wavelength ntawm 395nm. Los ntawm kev tsim tshwj xeeb, UVLED tuaj yeem tso tawm ib qho kev ua tiav tas mus li ultraviolet lub teeb kom ua tau raws li cov kev xav tau ntawm cov khoom lag luam ntawm ntug kev sib khi thiab kev sib txuas, luam ntawv thiab kho. UV LED lub teeb ci muaj lub neej ntev, lub teeb txias txias, tsis muaj hluav taws xob hluav taws xob, lub neej tsis cuam tshuam los ntawm tus naj npawb ntawm qhov qhib thiab kaw, lub zog siab, kev siv hluav taws xob tsis zoo txhim kho kev tsim khoom, thiab tsis muaj tshuaj lom. Nws muaj kev nyab xeeb thiab zoo ib puag ncig ntau dua li cov teeb pom kev zoo ib txwm muaj.
Kev faib tawm ntawm UV wavelength:
1. UVA: Lub wavelength yog 320-390nm, tseem hu ua ntev-yoj dub qhov chaw nyhuv ultraviolet rays. Nws muaj zog nkag mus rau hauv lub zog thiab tuaj yeem nkag mus rau feem ntau pob tshab iav thiab yas. Ntau tshaj 98% ntawm cov hluav taws xob ultraviolet ntev uas muaj nyob rau hauv tshav ntuj tuaj yeem nkag mus rau ozone txheej thiab huab kom ncav cuag lub ntiaj teb.
2. UVB muaj lub wavelength ntawm 280-320nm, tseem hu ua nruab nrab-yoj erythema nyhuv ultraviolet rays. Nruab nrab nkag mus rau hauv lub hwj chim, nws luv luv wavelength ib feem yuav absorbed los ntawm lub pob tshab iav, feem ntau ntawm nruab nrab-yoj ultraviolet muaj nyob rau hauv tshav ntuj yog absorbed los ntawm lub ozone txheej, thiab tsuas yog tsawg tshaj li 2% tuaj yeem ncav cuag lub ntiaj teb, uas yog tshwj xeeb muaj zog nyob rau lub caij ntuj sov thiab yav tav su.
3. Lub wavelength ntawm UVC yog qis dua 280nm, uas tseem hu ua luv-yoj sterilization ultraviolet. Nws lub peev xwm nkag mus tau tsis muaj zog, tsis tuaj yeem nkag mus rau feem ntau ntawm cov iav pob tshab thiab yas. Lub luv luv-yoj ultraviolet rays uas muaj nyob rau hauv tshav ntuj yog yuav luag tag absorbed los ntawm ozone txheej. Luv-yoj ultraviolet rays yog teeb meem heev rau tib neeg lub cev. Lub sij hawm luv luv tuaj yeem hlawv daim tawv nqaij, thiab qhov ntev ntev los yog siv zog heev tuaj yeem ua rau mob qog noj ntshav. UV high-pressure mercury teeb thiab ultraviolet germicidal teeb emit UVC luv-yoj ultraviolet rays.
4. UVD wavelength yog 100 ~ 200nm, tseem hu ua lub tshuab nqus tsev ultraviolet.
