Puas LED Teeb Bead Yellowing qhia txog teeb meem nrogZoo? A Scientific Justification
Txheej txheem cej luam
LED teeb muaj npe nrov rau lawv cov teeb pom kev zoo, kev ua neej ntev, thiab kev siv hluav taws xob. Tab sis nrog lub sijhawm, ntau tus neeg siv khoom pom tias cov iav lo ntsiab muag ntawm LED teeb hlaws ua daj, tsa cov lus nug txog qhov zoo ntawm cov khoom. Qhov no yellowing yog ib tug natural tshwm sim los yog ib tug flaw? Qhov ua rau ntawm LED yellowing, seb nws yog ib qho kev qhia tsis zoo, thiab cov kev daws teeb meem raug tshuaj xyuas hauv kab lus no.
Vim li cas cov hlaws dai ntawm LED teeb tig daj?
Cov yas lo ntsiab muag lossis cov khoom siv encapsulation (feem ntau silicone lossis epoxy resin) uas npog cov nti LED yog qhov uas LED yellowing feem ntau tshwm sim. Ntawm cov hauv paus ntsiab lus yog:
1. Kev degradation ntawm cov ntaub ntawv los ntawm tshav kub Txawm hais tias cov LEDs muaj zog ntau dua -ntau npaum li incandescent qhov muag teev, txuas mus rau qhov kub thiab txias yuav deteriorate cov khoom lens.
Cov LEDs pheej yig dua feem ntau siv epoxy resin, uas yog cuam tshuam rau thermal oxidation thiab discoloration.
Txawm hais tias cov lo ntsiab muag silicone muaj peev xwm tiv taus cua sov, lawv tseem tuaj yeem tawg hauv qhov chaw hnyav.
2. Raug UV Teeb
Ib qho me me ntawm ultraviolet (UV) hluav taws xob tawm los ntawm qee lub teeb LED muaj peev xwm ua rau photochemically deteriorate yas lo ntsiab muag.
Vim tias lawv raug tshav ntuj ncaj qha, LED teeb sab nraum zoov yog qhov yooj yim dua.
3. Cov tshuaj tiv thaiv kab mob nrog Environmental Elements
Yellowing tuaj yeem ua kom nrawm nrawm los ntawm kev raug oxygen, dampness, lossis cov kab mob sib kis (xws li leej faj hauv cov chaw ua haujlwm).
Cov khoom siv lo ntsiab muag yuav hnov mob nrog qee cov tshuaj ntxuav (xws li cawv lossis cov tshuaj uas muaj ammonia).
4. Cov khoom siv subpar
Tsawg- cov neeg tsim hluav taws xob LED tuaj yeem siv cov epoxy resin tsis zoo, uas yellows sai dua.
Vim hais tias cov lo ntsiab muag silicone los yog polycarbonate muaj kev tiv thaiv ntau dua rau cov daj, siab - LEDs zoo siv lawv ntau zaus.
Puas yog LED Kev Ua Haujlwm tau cuam tshuam los ntawm Yellowing?
Ntau tus neeg txhawj xeeb tias yellowing yuav ua rau tej yam tsis zoo los yog ua haujlwm zoo. Tab sis:
Yam tsawg kawg nkaus ntawm lub teeb tso zis: Tsuas yog lub lens discolors; LED nti nws tus kheej nyob twj ywm ua haujlwm.
Cov xim kub ntawm lub teeb dawb tuaj yeem hloov me ntsis los ntawm yellowing, uas tuaj yeem ua rau txo qis lub teeb pom kev zoo.
Tsis Muaj Hluav Taws Xob Hluav Taws Xob: Tsis muaj kev cuam tshuam rau LED lub voj voog.
Qhov teeb meem yuav yog phosphor degradation, uas tsis cuam tshuam rau lub lens yellowing, yog tias LED tseem ua haujlwm tab sis zoo li dimmer.
Case Studies: Cov duab piv txwv
Case 1: Kev soj ntsuam ntawm lub tsev LED teeb tig daj tom qab ob xyoos: Ib tug neeg siv pom tias daj me ntsis tshwm rau ntawm lawv cov teeb LED pheej yig.
Ua rau: Tsis zoo cua sov dissipation nyob rau hauv cov khoom sib txuas ua ke nrog pheej yig epoxy resin.
Kev daws: Qhov teeb meem tau kho los ntawm kev hloov kho qhov cua lossis hloov mus rau silicone -coated LEDs.
Case 2: Yellowing of Street Lights in Coastal Areas: Nws tau pom tias cov teeb pom kev hauv nroog hauv hiav txwv tig daj sai dua li cov hauv av.
Ua rau: Degradation tau nrawm nrawm los ntawm dej ntsev dampness thiab UV raug.
Kev daws: Lub neej ntev tau txuas ntxiv los ntawm kev siv cov lo ntsiab muag silicone uas tiv taus UV.
Txoj hauv kev kom tsis txhob LED Yellowing
1. Xaiv Premium LEDs
Es tsis txhob epoxy lo ntsiab muag, nrhiav silicone lossis polycarbonate sawv daws yuav.
Cov ntaub ntawv zoo dua yog siv los ntawm hom xws li Osram, Cree, thiab Philips.
2. Tshawb xyuas qhov tsim nyog ntawm qhov cua sov
LEDs yuav tsum tsis txhob siv nyob rau hauv tag nrho cov fixtures tshwj tsis yog tias lawv raug ntsuas rau kev siv.
Xyuas kom tseeb tias cov dab dej kub ua haujlwm tau raug.
3. Ua kom pom tseeb ntawm qhov chaw hnyav
Xaiv IP65+ (waterproof thiab dustproof) ntsuas LEDs rau kev siv sab nraum zoov.
Tsis txhob siv tshuaj, xws li tshuaj ntxuav tes.
4. Kev tu tsis tu ncua
Siv cov phuam qhuav los yog moist me ntsis los maj mam ntxuav LED qhov chaw.
Hloov cov qhov muag teev uas dimming lossis yellowing loj.
Puas Yellowing qhia tias tsis zoo?
Xyoo ntawm cov xim daj me ntsis qhia tias kev laus ib txwm muaj, tshwj xeeb nrog cov LEDs kim dua.
Kev yellowing sai (hauv lub hlis) yog ib qho cim ntawm cov khoom siv tsis zoo lossis cov cua sov ntau dhau.
High -zoo silicone / polycarbonate lo ntsiab muag yog siv los tiv thaiv yellowing nyob rau hauv hwm LEDs.
Yog tias koj lub LED hloov daj dhau sai, nws tuaj yeem yog qhov cim ntawm kev tsim khoom tsis zoo, kev teeb tsa tsis tsim nyog- cuam tshuam txog cua sov, lossis raug rau ib puag ncig hnyav.
Kev txhim kho yav tom ntej: zam LED daj
Cov neeg tsim khoom thiab cov kws tshawb fawb tau tsom mus rau:
sophisticated encapsulating cov ntaub ntawv (xws li sib tov ntawm silicone thiab epoxy).
coatings uas tsis suav nrog UV teeb kom txo cov photodegradation.
polymers nrog tus kheej - kho cov khoom uas tsis ploj mus.
Hauv kev xaus
LED teeb hlaws yellowing feem ntau yog qhov tshwm sim ntawm cov khoom qub, cua sov, thiab ib puag ncig raug ntau dua li qhov tsis zoo. Kev yellowing ntxov ntxov, txawm li cas los xij, tej zaum yuav yog ib qho cim ntawm kev tsim khoom tsis zoo lossis siv tsis tsim nyog. Cov neeg siv tuaj yeem ua kom lub neej ntev thiab kev zoo nkauj ntawm lawv lub teeb pom kev zoo LED los ntawm kev xaiv siab - LEDs zoo, ua kom cov cua sov tswj tau zoo, thiab zam qhov chaw hnyav.
Cov Lus Qhia Kawg: Kom ua kom muaj zog ntxiv, xav txog kev hloov mus rau silicone -coated lossis industrial- qib LEDs yog tias koj cov xim daj yooj yim.
