Txawm li cas los xij, dhau sijhawm, LED qhov ci tuaj yeem txo qis, uas yog hu ua lumen depreciation. Qhov no tuaj yeem ua rau lub teeb pom kev tsis sib xws thiab cuam tshuam rau kev ua haujlwm ntawm qhov system.

• Incorrect Binning: Yog hais tias LEDs tsis raug txheeb xyuas los yog ua pab pawg thaum lub sij hawm binning. Nws tuaj yeem ua rau tsis sib haum xeeb hauv kev ua haujlwm thiab xim. Qhov no tuaj yeem ua rau muaj teeb meem nrog lub teeb pom kev zoo.

• Tus nqi: Binning LEDs tuaj yeem yog tus txheej txheem kim. Nws xav tau cov cuab yeej tshwj xeeb thiab cov neeg ua haujlwm txawj. Yog li, qhov no tuaj yeem cuam tshuam tus nqi tag nrho ntawm lub teeb pom kev zoo.

Yuav ua li cas kuaj lub Binned LED?

Txhawm rau kuaj cov binned LED, koj yuav tsum ua raws li cov kauj ruam no:

Kauj Ruam 1: Txuas lub LED mus rau qhov chaw fais fab: Txuas lub LED qhov zoo coj mus rau lub hwj chim qhov zoo ntawm lub davhlau ya nyob twg. Tom qab ntawd kov cov nqi tsis zoo rau lub davhlau ya nyob twg tsis zoo. Thiab yog li tshuaj xyuas yog tias LED glows lossis tsis. 

Kauj Ruam 2: Ntsuas qhov voltage thiab tam sim no: Siv ib lub multimeter los ntsuas qhov voltage hla lub LED thiab tam sim no ntws los ntawm nws.

Kauj ruam 3: Xam tus nqi ntawm tus Resistor: Siv Ohm txoj cai los xam tus nqi ntawm tus resistor. Tus qauv yog R = (Vsource – Vf) / Yog

Kauj Ruam 4: Sib piv Cov Nyeem Ntawv nrog Cov Lus Qhia: Txheeb xyuas cov ntaub ntawv ntawm LED kom pom tias qhov kev cia siab ntawm qhov hluav taws xob thiab qhov tam sim no yuav tsum yog rau qhov binned LED. Sib piv cov kev nyeem los ntawm multimeter nrog cov specifications.

Kauj Ruam 5: Saib Lub Teeb Pom Kev: Yog tias qhov ntsuas hluav taws xob thiab qhov kev nyeem tam sim no phim cov kev qhia tshwj xeeb, saib xyuas lub teeb tawm ntawm LED. Yog tias nws tsis yog raws li qhov xav tau, tej zaum yuav muaj teeb meem nrog LED.

Kauj Ruam 6: Rov ua qhov kev sim nrog ntau lub zog: Rov ua qhov kev ntsuam xyuas nrog lub zog sib txawv kom ntseeg tau tias LED ua haujlwm raug.

Nco ntsoov: Binned LEDs yog categorized raws li lawv cov voltage thiab tam sim no. Nws yog ib qho tseem ceeb los ntsuam xyuas cov txiaj ntsig no kom ntseeg tau tias LED ua haujlwm raug.

Lub tswv yim rau Optimizing koj LED Binning txheej txheem

• Kom meej meej txhais koj xav tau LED binning tsis: Txheeb xyuas cov kev txwv koj xav siv rau binning. Xws li xim kub, luminous flux, thiab pem hauv ntej voltage. Qhov no yuav xyuas kom meej tias tag nrho cov LEDs raug soj ntsuam raws li cov qauv qub.

• Siv cov txheej txheem kev xeem zoo ib yam: Siv cov kev sim zoo ib yam thoob plaws hauv cov txheej txheem binning. Qhov no tej zaum yuav suav nrog kev siv tib cov cuab yeej thiab cov txheej txheem ntsuas, thiab, kev sim rau txhua qhov LED.

• Siv automated binning software: Automated binning software tuaj yeem txhim kho cov txheej txheem binning. Tsis tas li ntawd, nws tuaj yeem txo qhov peev xwm ntawm tib neeg kev ua yuam kev. Cov kev pab cuam no tuaj yeem txiav cov LEDs rau hauv cov thawv sib txawv.

• Khaws cov ntaub ntawv ntxaws ntxaws: Khaws cov ntaub ntawv ntxaws ntxaws tuaj yeem pab daws teeb meem txhua yam teeb meem uas yuav tshwm sim. Ib yam li rau yav tom ntej siv. Qhov no yuav suav nrog cov ntaub ntawv hais txog cov cuab yeej kuaj siv. Tsis tas li ntawd, cov binning tsis thiab cov txiaj ntsig ntawm txhua qhov kev xeem.

• Tsis tu ncua tshuaj xyuas thiab kho koj cov txheej txheem binning: Kev tshuaj xyuas thiab hloov kho koj cov txheej txheem binning tuaj yeem ua kom koj ib txwm tau txais txiaj ntsig zoo tshaj plaws. Thiab nws yuav daws tau cov teeb meem yav dhau los.

Xav txog daim ntawv thov zaum kawg: Qhov no yuav pab koj txheeb xyuas qhov tseem ceeb binning parameter. Nws xyuas kom meej tias koj xaiv cov LEDs zoo tshaj plaws rau cov ntawv thov tshwj xeeb.
