Yuav siv cov additives li cas los txhim kho qhov ci ntawm lub teeb ntawm LED teeb
Tam sim no, lub zog txuag hluav taws xob thiab cov teeb pom kev zoo ib puag ncig tau dhau los ua neeg nyiam, thiab ntau thiab ntau tus neeg mob siab rau txoj kev loj hlob ntawm LED teeb npog cov ntaub ntawv. Cov ntaub ntawv npog lub teeb no muaj xws li PC (polycarbon), PMMA (acrylic), thiab lwm yam. Nws tuaj yeem ua tiav li cas lub teeb ci LED tsis dazzling, thiab tuaj yeem ua kom lub teeb ci ntawm LED? Qhov ntawd yog lub teeb diffusing tus neeg sawv cev uas txhua tus neeg feem ntau tham txog. Lub teeb diffusing tus neeg sawv cev no tuaj yeem ua tiav qhov muag ntawm LED teeb los ntawm kev hloov pauv kev nthuav tawm ntawm lub teeb ntau zaus hauv substrate, thiab tib lub sijhawm, nws tuaj yeem txhim kho qhov yooj yim siv cov xim hmoov los kho qhov tsis muaj lub teeb ci, vim hais tias lub toner yuav thaiv ntau lub teeb nyob rau hauv lub substrate, ua rau lub brightness tsaus, thiab nws tsis tuaj yeem thaiv ntau lub teeb hla dhau zoo li kev siv cov organic teeb diffusers.
Puas muaj tus neeg saib xyuas lub teeb diffusing ua cov khoom siv kho qhov muag LED yuav tsis cuam tshuam qhov ci ntsa iab (lub teeb transmittance)?
Peb tuaj yeem txheeb xyuas qhov no los ntawm lub teeb diffusing cov neeg siv tam sim no. Tam sim no lub teeb diffusing agents yog:
Inorganic teeb diffusers thiab organic teeb diffusers.
Inorganic light diffusing agents mas muaj xws li: nano barium sulfate, calcium carbonate, silicon dioxide, thiab lwm yam. Cov inorganic light diffusing agents thiab inorganic light diffusing agents yog cov khoom microbeads los ntawm qhov kev pom ntawm lub microscopic, thiab lub teeb tsis tuaj yeem dhau los ntawm cov khoom no. kev sib kis ntawm ntau lub teeb, thiab tsuas yog ib feem ntawm lub teeb yuav dhau los ntawm refraction, yog li cuam tshuam rau qhov ci ntsa iab lossis lub teeb xa mus. Tam sim no, yog tias lub teeb xa hluav taws xob ntawm lub teeb pom kev zoo siab tshaj 50 feem pua, inorganic teeb diffusing tus neeg sawv cev tsis tuaj yeem xaiv.
Organic light diffusing agents mas muaj xws li acrylic type, styrene type, acrylic resin type, etc. Cov resins no yog pob tshab los yog translucent, thiab feem ntau ntawm lub teeb yuav dhau mus. Vim qhov sib txawv ntawm qhov ntsuas qhov taw qhia, tom qab lub teeb refracted ntau zaus, lub teeb hla ntawm lub substrate yuav ci thiab muag muag, thiab muaj kev cuam tshuam me ntsis ntawm lub teeb kis ntawm cov khoom. Nws yog ib qho kev xaiv zoo rau cov khoom siv kho qhov muag xws li lub teeb ntxoov ntxoo.
Nws tuaj yeem pom los ntawm kev txheeb xyuas saum toj no tias cov organic teeb diffusing tus neeg sawv cev yog lub teeb diffusing tus neeg sawv cev S rau cov khoom siv ntawm cov khoom siv hauv paus xws li PC thiab acrylic. Vim tias muaj ntau hom organic teeb diffusing agents, thiab lawv cov ntaub ntawv lawv tus kheej muaj qhov sib txawv refractive indices ntawm lub teeb, muaj ntau yam kev faib tawm ntawm lub teeb diffusing agents rau PC teeb ntxoov thiab lub teeb diffusing agents rau PMMA teeb ntxoov.
Vim li cas cov organic teeb diffusing tus neeg sawv cev ua rau cov khoom siv kho qhov muag ntawm LED tube teeb lub teeb tsis cuam tshuam qhov ci ntau dhau?
Cov neeg kho tshuab lub teeb tam sim no diffusing tus neeg saib xyuas nano- hlaws, cov khoom siv nws tus kheej tuaj yeem xa lub teeb, uas daws teeb meem ntawm teeb pom kev zoo thiab teeb pom kev zoo. Tom qab ntau lub sij hawm ntawm lub teeb refraction, lub teeb pom kev zoo yog tiav, thiab kev poob ntawm lub teeb xa hluav taws xob tsawg dua. Cov organic nano-particle no yog ib hom me me pob tshab kheej kheej, uas yog ntxiv rau PC, PMMA, PVC, thiab potting kua nplaum, thiab tuaj yeem sib npaug sib npaug hauv cov resin. Qhov teeb meem tshwm sim dhau los ntawm lub iav kheej kheej thiab dhau los ntawm iav lub cev suav tsis txheeb. refraction, thiab tom qab ntawd nkag mus. Xws li lub teeb khaus yog refracted thiab tusyees dispersed. Qhov taw tes lub teeb ci yog hloov mus rau hauv qhov chaw teeb pom kev zoo, uas nthuav tawm lub teeb-emitting nto, thiab ua rau lub teeb muag muag heev. Nyob rau tib lub sijhawm, lub teeb tuaj yeem nkag mus rau hauv lub iav kheej kheej, yog li qhov poob ntawm lub teeb me me, thiab nws kuj ua lub luag haujlwm ntawm lub teeb pom kev zoo thiab lub teeb sib kis.
Yog tias cov khoom siv kho qhov muag PC xav kom ua tiav lub teeb diffusing nyhuv thiab muaj haze zoo dua, yuav ua li cas xaiv lub teeb diffusing tus neeg sawv cev?
Kev xaiv lub teeb diffusing tus neeg sawv cev yuav tsum tau xyuam xim rau cov hauv qab no
1. Xaiv cov khoom siv ntau lub teeb diffusing. Qhov luaj li cas ntawm cov khoom siv ntau lub teeb diffusing tus neeg sawv cev yog qhov sib txawv, uas tuaj yeem ua kom lub teeb pom kev zoo ntau zaus thiab muaj qhov kub hnyiab zoo. Lub haze ntawm ib leeg-component lub teeb diffusing tus neeg saib xyuas tsis zoo li ntawm ntau lub teeb diffusing tus neeg saib xyuas, tab sis lub teeb transmittance ntawm ib leeg-component lub teeb diffusing tus neeg saib xyuas yog zoo dua.
2. Lub refractive index ntawm cov khoom xaiv lub teeb diffusing tus neeg sawv cev yuav tsum txawv ntawm qhov refractive index ntawm cov khoom siv hauv paus, tab sis qhov sib txawv yuav tsum tsis txhob loj dhau. Qhov loj dhau qhov sib txawv yuav ua rau qhov tshwm sim ntawm tag nrho cov kev xav, uas yuav tsis ua raws li qhov yuav tsum tau muaj ntawm lub teeb diffusion thiab kis tau tus mob.
3. Yuav kom ua tau zoo PC lossis PMMA cov khoom siv kho qhov muag, lub teeb diffusion yuav tsum xaiv hom lub teeb diffusing tus neeg sawv cev, kom lub teeb npog yog qhov hnyav, thiab lub teeb xa hluav taws xob siab tsis tuaj yeem ua tiav, uas cuam tshuam rau qhov xav tau tiag tiag.
