Vim li cas silicone lens LED tau muaj hnub nyoog daj nrog uv teeb?
Silicone lo ntsiab muag siv nrog LED teeb kuj tuaj yeem ua daj lossis tsis muaj xim thaum raug ultraviolet (UV) lub teeb rau cov laj thawj zoo sib xws raws li tau hais hauv cov lus teb dhau los. Nov yog vim li cas silicone lo ntsiab muag rau LED teeb tuaj yeem muaj hnub nyoog thiab tig daj vim raug UV:
Cov tshuaj tiv thaiv UV-induced:UV teeb tuaj yeem pib ua tshuaj lom neeg hauv cov khoom siv silicone. Qhov no muaj tseeb rau ob qho tib si silicone lo ntsiab muag siv hauv LED teeb thiab lwm yam khoom siv silicone. Kev raug UV hluav taws xob tuaj yeem rhuav tshem cov tshuaj lom neeg hauv silicone, ua rau muaj kev hloov pauv hauv nws cov qauv molecular uas ua rau muaj xim daj lossis xim daj.
Photodegradation:UV hluav taws xob tuaj yeem ua rau photodegradation ntawm cov khoom siv silicone. Cov txheej txheem no suav nrog kev rhuav tshem cov ntawv cog lus molecular thiab tsim cov tshuaj tshiab hauv cov lus teb rau UV raug. Sij hawm dhau mus, qhov no tuaj yeem hloov kho qhov muag ntawm lub lens silicone thiab ua rau nws pom daj.
Tsim cov chromophores:UV teeb pom kev tuaj yeem ua rau tsim cov chromophores hauv silicone. Chromophores yog ib pawg tshuaj uas nqus lub teeb nyob rau hauv qhov pom spectrum, uas tuaj yeem ua rau cov khoom tsis muaj xim lossis daj. Cov chromophores tshwj xeeb uas tsim nyob rau hauv silicone lo ntsiab muag vim UV raug tuaj yeem sib txawv nyob ntawm seb cov khoom siv silicone thiab cov xwm txheej raug.
Environmental Factors:Cov degree uas silicone lo ntsiab muag rau LED teeb daj vim UV raug tuaj yeem nyob ntawm ntau yam ib puag ncig, suav nrog kev siv thiab lub sijhawm ntawm UV raug, lub wavelength ntawm UV lub teeb tawm los ntawm LED, thiab muaj lwm yam khoom lossis cov kab mob hauv lub cev. ib puag ncig.
Txhawm rau txo qhov yellowing thiab aging ntawm silicone lo ntsiab muag siv nrog LED teeb, nws yog ib qho tseem ceeb uas yuav tau xav txog cov hauv qab no:
Siv cov ntaub ntawv UV-resistant:Xaiv cov khoom siv silicone nrog UV-resistant zog los yog coatings tshwj xeeb tsim los siv nrog LED teeb. Cov ntaub ntawv no tsis tshua muaj xim daj thiab degradation thaum raug UV hluav taws xob.
Kev tswj kom zoo:Xyuas kom meej tias cov lo ntsiab muag silicone siv nrog LED teeb ua tau raws li cov qauv kev ua tau zoo thiab kev ua haujlwm. Cov lo ntsiab muag zoo thiab cov txheej txheem tsis tshua muaj peev xwm degrade sai.
Cov txheej txheem tiv thaiv:Siv cov txheej tiv thaiv ntawm silicone lo ntsiab muag los thaiv lossis nqus UV hluav taws xob. Cov txheej txheej no tuaj yeem pab ntev lub lens qhov pom qhov pom tseeb thiab pom.
Tswj ib puag ncig:Yog tias ua tau, xav txog kev siv cov teeb ci LED thiab silicone lo ntsiab muag hauv qhov chaw tswj hwm nrog txo UV raug.
Los ntawm kev siviav lens ntim UV smd leds,koj yuav tsis muaj teeb meem mob taub hau txog qhov cuam tshuam ntawm UV-induced yellowing thiab aging.
