Puas yog koj lub Hoobkas Photolithography tseem siv qub -Fashioned Yellow Light Tubes? Yuav Ua Li Cas T8 LED Tau Txais "Zero Blue Light" Thaum Txuag Hluav Taws Xob?
Hauv semiconductor thiab PCB photolithography, lub teeb daj daj yog "thawj kab ntawm kev tiv thaiv" los tiv thaiv photoresist los ntawm ua ntej - raug. Txawm li cas los xij, ntau lub chaw tsim khoom tseem siv cov raj fluorescent daj los yog qis -kawg LED cov raj daj - txawm tias cov spectral filtering tsis tiav, lossis lumen depreciation yog hnyav, yuav tsum tau hloov ntau zaus.Qhov tseeb T8 LED lub teeb daj lub teeb ua haujlwm li cas?Thiab vim li cas nws thiaj dhau los ua tus qauv rau cov chaw teeb pom kev daj niaj hnub no? Kab lus no piav qhia los ntawm peb qhov tseem ceeb technical dimensions.
1. Qhov taw qhia tseem ceeb tshaj plaws rau Photolithography teeb pom kev zoo: Tsis Brightness, Tab sis "Spectral Purity"
Ntau tus neeg siv yuam kev ntseeg tias ntev npaum li lub raj tso tawm lub teeb daj, nws txaus - qhov no yog qhov tsis to taub loj. Photoresist yog rhiab heev rauLub teeb xiav, violet lub teeb, thiab ultraviolet lub teeb hauv qab 500nm. Txawm hais tias lub teeb pom daj rau ntawm qhov muag liab qab, yog tias lub spectrum muaj me me ntawm luv luv - wavelength Cheebtsam, nws tseem tuaj yeem ua rau "kev raug dab", ua rau tag nrho cov khoom ntawm wafers.
Lub hauv paus ntawm Benwei T8 LED daj lub teeb raj nyob hauvdual thaiv los ntawm ib qho tshwj xeeb formulated daj phosphor + optical - qib PC lim npog, kom ntseeg tau tias cov zis spectrum poob tag nrho hauv 570nm-590nm ntau yam,nyob ze -zero transmittance rau wavelengths hauv qab 500nm. Qhov no yog qhov muaj kev ntseeg siab dua li cov iav pleev xim zoo tib yam lossis cov xim daj LED tsis zoo.
Txhawm rau txheeb xyuas qhov no, cov neeg siv kev tshaj lij siv aspectroradiometer. Ib lub teeb daj uas tsim nyog yuav tsum muaj irradiance qis dua 0.1μW / cm² / nm ntawm 450nm. Benwei cov ntaub ntawv ntsuas tau zoo dua li tus qauv no.
2. Los ntawm "Zoo" mus rau "Stable": Yuav ua li cas LED Chips thiab cov khoom siv fais fab txiav txim siab Uniformity?
Tsis yog- qhov ci ci tsis sib xws ntawm qhov chaw ua haujlwm photolithography ua rau cov kab dav tsis sib haum ntawm ntau qhov chaw ntawm tib lub wafer. Kev lag luam xav tauuniformity Ntau dua los yog sib npaug rau 95%(piv txwv li, qhov piv ntawm qhov siab tshaj plaws rau qhov ci ntsa iab tsawg tshaj li lossis sib npaug rau 1.05). Qhov no nyob ntawm ob yam:
- Kev sib raug zoo ntawm LED chips: Benwei siv siab -brightness daj- muab cov chips los ntawm Taiwan Epistar, nrog wavelength binning nruj me ntsis tswj nyob rau hauv ± 2.5nm, kom tsis txhob muaj xim txawv.
- Tsis tu ncua tam sim no precision ntawm lub hwj chim mov: Ua -nyob rau hauv cais fais fab mov nrog Rubycon capacitors, tso zis tam sim no ripple<3%, eliminating flicker and brightness fluctuations at the source.
Nyob rau hauv sib piv, pheej yig LED daj raj feem ntau siv resistor - capacitor dropper fais fab mov, uas tsis tsuas yog muaj ib tug luv luv lifespan tab sis kuj raug kev txom nyem los ntawm loj brightness drift nrog kub, ua rau lawv kiag li tsis haum rau precision txheej txheem.
3. Cov ntaub ntawv sib piv: Vim li cas koj yuav tsum saib L90 Lifespan kom "Txuag Nyiaj"
Ntau tus neeg yuav khoom tsuas yog saib xyuas tus nqi pib, tsis quav ntsej txogtag nrho lifecycle tus nqi. Cov lus hauv qab no ncaj qha piv qhov kev ua tau zoo ntawm peb hom teeb daj (siv 4-ko taw T8 raj ua piv txwv):
| Cov khoom sib piv | Tsob Ntoo Fluorescent Yellow Tube | Tsawg-End LED Yellow Tube | Benwei T8 LED Yellow Tube |
| Lub teeb xiav / violet (<500nm) filtration rate | ~ 90% (degrades raws sijhawm) | ~ 95% (LED nti drift common) | >99.9% (ntev rau lub neej) |
| Hom fais fab | 36W | 18W | 18W |
| Luminous flux | 2 400 lm | 2000lm (feem ntau exaggerated) | 2200lm ( ntsuas, raug) |
| L70 lub neej | 8,000h | 15,000h | >50,000h |
| L90 lub neej | Tsis siv tau | Tsis muaj ntaub ntawv | >50,000h (LM-80 ntawv pov thawj) |
| Tag nrho 3-xyoo tus nqi (hluav taws xob + hloov ua haujlwm) | 100% | ~65% | ~35% |
| Muaj mercury | Yog lawm | Tsis muaj | Tsis muaj |
Raws li pom nyob rau hauv lub rooj: txawm hais tias tus nqi pib ntawm kev yuav khoom ntawm Benwei T8 LED lub teeb daj lub teeb yog me ntsis siab dua li qis dua -kawg LED raj, nwsL90 lifespan tshaj 50,000 teevtxhais tau tias nws tuaj yeem khiav tau ze li ntawm 6 xyoo yam tsis muaj kev hloov pauv raws li kev tsim khoom ib txwm muaj (24 teev / hnub). Hauv qhov sib piv, qis-kawg LED raj yuav poob ntau dua 30% ntawm lawv cov luminous flux tom qab kwv yees li 2 xyoos, ua rau muaj qhov sib txawv ntawm qhov sib txawv tshaj qhov tshwj xeeb.
4. Tshaj li Photolithography: "Hidden Functions" ntawm Yellow Light Tubes Koj Yuav Tsis Paub
Tus nqi ntawm T8 LED daj lub teeb raj txuas mus deb tshaj semiconductor fabs. Lawv sib npaug indispensable nyob rau hauv cov xwm txheej hauv qab no:
- PCB solder mask (green oil) txheej txheem– kuj yuav tsum tau UV- teeb pom kev zoo.
- Tsev khaws puav pheej / Archives- tiv thaiv fading ntawm artifacts thiab ancient phau ntawv tshwm sim los ntawm teeb pom kev zoo.
- Cov chav huv huv- lub teeb daj txo cov yoov tshaj cum (ntau dua wavelength, tsawg txaus nyiam rau kab).
- Cov chaw ua haujlwm hmo ntuj- lub teeb daj ua rau melatonin tsawg dua lub teeb xiav / dawb, pab tiv thaiv cov neeg ua haujlwm pw tsaug zog.
Benwei cov khoom muaj nyob rau hauvpob tshab daj(siab dua brightness) thiabfrosted daj(ntau yam teeb pom kev zoo) npog, haum rau ntau qib kev huv huv thiab tiv thaiv- qhov yuav tsum tau ua glare. Lawv kuj tseem muaj V2 nplaim hluav taws retardant ntsuam xyuas thiab IP20 tiv thaiv, ncaj qha hloov cov tsoos T8 tuav.
5. Kev ceeb toom xaiv: Yuav ua li cas txheeb xyuas qhov tseeb "Photolithography-Qib" Yellow Light Tubes?
Ntau yam li-hu ua "daj lub teeb raj" ntawm kev ua lag luam tsuas yog cov LEDs zoo tib yam nrog lub ntsej muag daj diffuser - lub teeb xiav tseem dhau mus. Nco ntsoov nug tus neeg muag khoom rau aspectrum duabthiab paub meej tias ob lub ntsiab lus hauv qab no:
- Relative siv ntawm 450nm<0.5%(hais txog lub ncov wavelength).
- Cov khoom tau dhau LM-80 lub neej kev simthiab muaj daim ntawv qhia L90.
Benwei tuaj yeem muab batch-cov ntawv ceeb toom tshwj xeeb spectrum xeem thiab cov ntaub ntawv qub LM-80 rau txhua T8 LED lub teeb daj lub raj, kom ntseeg tau tias txhua lub raj ua tau raws li cov txheej txheem photolithography.
Xaus: Teeb pom kev hauv thaj chaw photolithography yog tsis txhais tau tias "tsuas yog lub teeb daj xwb". Nws yuav tsum tau tswj nruj tshaj peb qhov ntev: spectral purity, brightness uniformity, thiab kev cia siab rau lub neej.Nrog hardcore nta xws li cov khoom siv los ntawm German, Taiwan Epistar chips, thiab Rubycon capacitor fais fab mov, Benwei T8 LED daj lub teeb raj tiag tiag ua tiav "zero xiav lub teeb, lub neej ntev, tsis tshua muaj nqi". Hloov ib zaug, tau txais txiaj ntsig rau rau xyoo.
