Sab nraum zoov teeb pom kev zoo yuav tsum tiv taus qhov kev sim ntawm cov dej khov thiab daus, cua thiab xob laim, thiab tus nqi siab heev. Vim tias nws yog qhov nyuaj rau kev kho ntawm phab ntsa sab nrauv, nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm ruaj khov mus ntev. LED yog ib qho khoom siv semiconductor zoo heev. Yog tias nws ntub, cov nti yuav nqus cov dej noo thiab ua rau cov LED, PcB thiab lwm yam khoom puas. Yog li ntawd, LED yog tsim rau ziab thiab kub tsis tshua muaj. Txhawm rau kom ntseeg tau tias lub sijhawm ua haujlwm ruaj khov ntawm LEDs nyob rau hauv qhov hnyav sab nraum zoov, cov qauv tsim cov teeb pom kev tsis zoo ntawm cov teeb yog qhov tseem ceeb heev.
Tam sim no, cov cuab yeej siv hluav taws xob tsis zoo ntawm cov teeb hluav taws xob feem ntau yog muab faib ua ob qho kev qhia: cov txheej txheem waterproofing thiab cov khoom siv waterproofing. Lub npe hu ua structural waterproofing yog tias tom qab kev sib xyaw ua ke ntawm ntau yam qauv ntawm cov khoom, nws tau ua dej tsis zoo. Cov khoom siv dej tsis zoo yog txoj haujlwm ntawm cov khoom siv hluav taws xob kaw thaum tsim khoom. Cov khoom siv kua nplaum yog siv los tiv thaiv dej thaum sib dhos.
Cov yam ntxwv cuam tshuam rau kev ua haujlwm tsis zoo ntawm cov teeb
1, Ultraviolet lub teeb
Ultraviolet rays muaj kev puas tsuaj rau cov hlau rwb thaiv tsev, txheej txheej tiv thaiv, cov khoom yas, cov kua nplaum nplaum, lub nplhaib sealing roj hmab sawb thiab cov nplaum raug rau sab nraud ntawm lub teeb.
Tom qab txheej rwb thaiv tsev hlau yog hnub nyoog thiab tawg, dej vapor yuav nkag mus rau sab hauv ntawm lub teeb los ntawm qhov sib txawv ntawm cov tub ntxhais hlau. Tom qab txheej txheej ntawm lub teeb vaj tsev yog hnub nyoog, txheej txheej ntawm ntug ntawm lub casing yog tawg los yog tev tawm, thiab qhov sib txawv yuav tshwm sim. Tom qab cov ntaub ntawv yas muaj hnub nyoog, nws yuav deform thiab tawg. Electron potting colloids tuaj yeem tawg thaum muaj hnub nyoog. Lub sealing rubber strip yog laus thiab deformed, thiab qhov sib txawv yuav tshwm sim. Cov nplaum nplaum ntawm cov tswv cuab ntawm cov txheej txheem yog hnub nyoog, thiab qhov sib txawv kuj tsim tom qab lub nplaum nplaum raug txo qis. Cov no yog tag nrho cov kev puas tsuaj rau lub peev xwm waterproof ntawm lub luminaire.
2, Qhov kub thiab txias
Qhov kub sab nraum zoov txawv heev txhua hnub. Thaum lub caij ntuj sov, qhov kub ntawm lub teeb tuaj yeem nce mus rau 50-60 degree , thiab qhov kub thiab txias poob rau 10-20 degree thaum yav tsaus ntuj. Qhov kub ntawm lub caij ntuj no thiab daus tuaj yeem poob qis dua xoom, thiab qhov kub thiab txias hloov pauv ntau dua thoob plaws hauv lub xyoo. Sab nraum zoov teeb pom kev zoo nyob rau hauv qhov kub thiab txias ib puag ncig nyob rau hauv lub caij ntuj sov, cov khoom accelerates kev laus deformation. Thaum qhov kub thiab txias poob qis dua xoom, cov khoom yas ua nkig, nyob rau hauv lub siab ntawm dej khov thiab daus los yog tawg.
3, Thermal Expansion thiab Contraction
Thermal expansion thiab contraction ntawm lub teeb vaj tsev nyob: Qhov kev hloov ntawm qhov kub thiab txias ua rau lub thermal expansion thiab contraction ntawm lub teeb. Lub coefficient ntawm linear expansion ntawm cov khoom sib txawv yog sib txawv, thiab ob cov ntaub ntawv yuav raug tshem tawm ntawm qhov sib koom ua ke. Cov txheej txheem ntawm thermal expansion thiab contraction yog rov ua dua tsis tu ncua, thiab cov txheeb ze hloov chaw yog rov ua tsis tu ncua, uas ua rau huab cua nruj heev ntawm lub teeb.
4, Waterproof Structure
Luminaires raws li cov qauv tsim dej tsis zoo yuav tsum tau nruj nruj nrog silicone sealing nplhaib. Lub txheej casing txheej yog ntau meej thiab nyuaj. Nws yog feem ntau haum rau cov teeb loj loj, xws li sawb dej nyab teeb, square thiab voj voog dej nyab, thiab lwm yam teeb pom kev zoo.
Txawm li cas los xij, cov qauv ntawm cov qauv tsim dej tsis zoo ntawm lub luminaire muaj qhov xav tau ntau dua rau kev ua haujlwm, thiab qhov ntev ntawm txhua qhov yuav tsum tau ua kom zoo sib xws. Tsuas yog cov khoom siv dej tsis zoo tuaj yeem lav nrog cov ntaub ntawv tsim nyog thiab kev tsim kho.
Lub sijhawm ntev kev ruaj ntseg ntawm cov qauv dej tsis zoo ntawm lub luminaire yog ze rau nws cov qauv tsim, kev ua tau zoo ntawm cov khoom siv teeb pom kev zoo, kev ua haujlwm raug, thiab kev sib dhos tshuab.
5, Txog Cov Khoom Siv Dej tsis zoo
Kev tsim cov dej tsis zoo ntawm cov khoom siv yog insulated thiab waterproofed los ntawm filling potting kua nplaum, thiab kev sib koom ua ke ntawm cov txheej txheem kaw yog sib koom ua ke los ntawm cov kua nplaum sealing, kom cov khoom siv hluav taws xob yog tag nrho airtight thiab ua tiav cov dej tsis zoo ntawm cov teeb pom kev zoo sab nraum zoov.
6, Cov kua nplaum nplaum
Nrog rau kev txhim kho cov khoom siv tsis muaj dej tsis zoo, ntau hom thiab hom tshwj xeeb potting glues tau tshwm sim tsis tu ncua. Piv txwv li, hloov kho epoxy resin, hloov kho polyurethane resin, hloov kho cov organic silica gel thiab lwm yam.
