Vim li cas peb thiaj li yuav tsum tau ntim cov xim dawb smd coj hauv iav lens es tsis txhob siv lub lens silicone?

Thaum peb pivdawb xim SMD LEDsnrogsilicone lo ntsiab muagpiviav (quartz) lo ntsiab muag, muaj ntau yam tseem ceeb ntsig txog kev ua haujlwm ntev, thermal stability, lub teeb kis tau tus mob, thiab qhov ci ntsa iab uas piav qhia txog kev xaiv ntawm cov khoom siv hauv kev siv sib txawv.

1. Kev kub kub ib puag ncig (piv txwv li, Steel Mills)

Nyob rau hauv high-temperature ib puag ncig zoo li asteel zeb, qhov twg qhov kub tuaj yeem ncav cuag 800 degree lossis ntau dua, cov lo ntsiab muag silicone muaj qhov tsis zoo piv rau quartz iav lo ntsiab muag. Nov yog vim li cas:

Silicone Lenses:Silicone yog cov khoom muag muag thiab hloov tau yooj yim, tab sis nws muaj ib qhoqis kub kam rau ua, feem ntau nyob ib ncig ntawm 200 degree mus rau 250 degree. Thaum raug kub kub dhau lub sijhawm, cov khoom siv silicone zoo li degrade, ua raudaj dajlos yogkev hloov xim. Cov txheej txheem kev laus no ua rau cov khoom tsis muaj zog, txo ob qho tib sipob tshabthiabkev ua tau zoontawm lub lens. Nyob rau hauv ib puag ncig hnyav, silicone lo ntsiab muag yuav poob sai sai, thiab LED yuav tsim lub teeb tsawg dua lub sijhawm.

Quartz iav Lenses:Piv txwv li,quartz iav(ib daim ntawv ntawm cov iav ua los ntawm silicon dioxide) yog ntau resistant rau kub kub, feem ntau withstanding kub mus txog rau.1000 degreetsis muaj qhov tseem ceeb degradation. Quartz iav tuav nwspob tshabthiabstructural kev ncaj nceestxawm nyob rau hauv huab cua txias, ua rau nws zoo tagnrho rau ib puag ncig zoo li steel mills, qhov twg qhov kub thiab txias tuaj yeem ua rau degradation sai ntawm lwm cov ntaub ntawv.

Yog li, hauv cov nokev siv kub kub, quartz iav lo ntsiab muag kom ntseeg taulub neej ntev duathiabkev ua tau zoo ib yamntawm LEDs, uas yog qhov tseem ceeb rau kev txo cov nqi kho thiab hloov cov nqi.

2. Brightness txo vim ntau qhov kev cuam tshuam

Tam sim no, hais txog lubbrightness txawvnruab nrab ntawm LEDs nrog silicone lo ntsiab muag thiab cov uas muaj quartz iav lo ntsiab muag, yog vim li cas rau qhov txo nyob rau hauv brightness nyob rau hauv lub iav-lens LEDs nyob rau hauv lubtus naj npawb ntawm refractionsLub teeb undergoes thaum nws dhau los ntawm cov khoom.

LED nrog Silicone Lens (2 Refractions):Nyob rau hauv ib tug raug silicone-lensed LED pob, lub teeb los ntawm LED nti undergoes ob refractions:

Los ntawm LED nti (feem ntau yog txheej epitaxial) rau hauvsilicone lens.

Los ntawmsilicone lensmus rau hauvhuab cua(los yog ib puag ncig ib puag ncig). Cov khoom siv silicone lens muaj qhov ntsuas qis qis, yog li lub teeb tsis tau khoov ntau dhau, thiab lub zog poob los ntawm cov refractions no kuj tsawg.

LED nrog Quartz iav Lens (3 Refractions):Thaum lub LED muaj ib tugquartz iav lens, lub teeb mus dhau ib kauj ruam ntxiv refraction:

Los ntawm LED nti mus rau hauvquartz iav.

Los ntawmquartz iavmus rau hauvhuab cua.

Thaum kawg, los ntawmhuab cuarov qab rau hauvquartz iavthaum lub teeb tawm ntawm lub lens thiab nkag mus rau huab cua ib puag ncig.

Txhua kauj ruam refraction ua rau apoob ntawm lub teeb sivvim lub teeb yog ib nrab reflected thiab absorbed ntawm txhua interface, txo covtag nrho brightnessntawm LED. Covsiab dua refractive indexntawm quartz iav (nyob ib ncig ntawm 1.46) piv rau silicone (uas muaj ib tug refractive index ntawm ib ncig ntawm 1.4) kuj txhais tau hais tias lub teeb yog khoov duav sharply, uas yuav ua rau tawg ntxiv thiab lub zog poob.

Txawm hais tias txo qhov ci ntsa iab vim muaj ntau qhov kev cuam tshuam ntau ntxiv, quartz iav lo ntsiab muag tseem nyiam nyob rau hauv ntau qhov kub thiab txias los yog tshwj xeeb kev siv vim lawvthermal stabilitythiabdurabilityoutweigh qhov txo qis hauv qhov ci. Tsis tas li ntawd, lubbrightness pooblos ntawm cov kauj ruam ntxiv refraction feem ntau tuaj yeem raug them nyiaj los ntawm kev tsim ntawm LED nws tus kheej, xws li kev siv cov chips muaj zog ntau dua los yog cov txheej txheem kho qhov muag zoo dua los txhim kho lub teeb pom kev zoo.

 

Cov ntsiab lus:

Quartz iav Lensesxav tau nyob rau hauvib puag ncig kubzoo li steel mills vim tias lawv tuaj yeem tiv taus qhov kub thiab txias ntau yam tsis muaj degrading, whereas silicone lo ntsiab muag yuav muaj hnub nyoog sai nyob rau hauv cov xwm txheej zoo li no.

Covtxo qhov cinyob rau hauv LEDs nrog quartz iav lo ntsiab muag tshwm sim vim lub teeb undergoespeb refractions(chip → iav → cua → iav → cua), piv rau tsuas yog ob refractions (chip → silicone → cua) nyob rau hauv silicone-lensed LEDs. Qhov no ua rau me ntsis txo qis hauv cov zis tawm vim muaj ntau qhov kev xav thiab kev cuam tshuam.

Hauv ib puag ncig qhov twgthermal stabilityyog ib qho tseem ceeb, xws li hauv cov ntawv thov kev lag luam, kev ua haujlwm ntev thiab kev ua haujlwm ntawmquartz iav lo ntsiab muagua rau lawv qhov kev xaiv zoo dua, txawm tias muaj kev lag luam me me hauv qhov ci ci.
