Yuav daws qhov teeb meem kub kub ntawm UV LED li cas?

Thaum lub teeb ci LED tau qhib, P-N txuas thaj chaw hauv lub nti pib ua haujlwm, tsim thiab khaws cov cua sov. Thaum twg lub xeev ua tiav qhov kev ruaj ntseg, qhov kub thiab txias yog hu ua qhov sib txuas kub.

Tsis tas li ntawd, vim hais tias cov nti tau raug encased, lub tshav kub ntawm lub semiconductor tsis tuaj yeem raug kuaj ncaj qha thaum lub sij hawm ntsuas. Yog li ntawd, qhov sov sov ntawm tus pin conductor feem ntau yog siv los ntsuas qhov kub ntawm qhov sib txawv ntawm lub teeb tsis ncaj qha. Qhov qis ntawm lub teeb qhov hluav taws xob qhov hluav taws xob sib txuas, qhov zoo dua nws cov cua sov dissipation.

Feem ntau, cov khoom uas tau xaiv rau lub teeb ci semiconductor thiab ntim cov duab nws siv tau muaj kev cuam tshuam ncaj qha rau lub tshav kub dissipation ntawm LED teeb qhov chaw.

Cov ntaub ntawv siv rau lub teeb ci LED tau txais qee yam hluav taws xob tiv thaiv sab hauv thiab sab nraud. Qhov loj ntawm cov kev tiv thaiv qhov tseem ceeb no qhia txog lub teeb ci qhov hluav taws xob muaj peev xwm ua kom sov rau qee qhov.

Teeb meem kub Dissipation

Thaum tshav kub kub dissipation yog ib hom hluav taws xob dissipation (lub zog hloov). Lo lus "zog dissipation" yog hais txog lub zog khib nyiab vim qhov kub thiab txias tsis zoo.

Thaum tshav kub kub yog dissipated los ntawm peb txheej txheem:

·  Convection yog txheej txheem cua sov los ntawm cov kua dej ntws. Piv txwv li, ib lub qhov cub convection, siv cua (rhuab, txav dej) los xa cov cua sov.

·  Kev coj ua yog cov txheej txheem los ntawm cov cua kub dissipated thoob plaws hauv ib qho khoom thiab tej zaum mus rau lwm yam khoom uas yuav tsum tau nyob rau hauv kov nrog cov khoom rhuab. Ib qho hluav taws xob cooktop rhuab los ntawm hluav taws xob tsis kam yog ib qho piv txwv.

·  Radiation yog txheej txheem los ntawm cov cua sov dispersed siv electromagnetic tsis. Lub qhov cub microwave yog ib qho piv txwv ntawm cov cua kub dissipation.

·  Kev siv cov rwb thaiv tsev tsim nyog rau daim ntawv thov txo cov cua sov thiab nws cov nqi thaum tseem txhawb kev ua haujlwm thiab kev nyab xeeb.

Yuav ua li cas daws qhov teeb meem kub dissipation

Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws nws nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus account qhov siab tshaj plaws ntawm UV-LED qhov chaw ntawm lub teeb uas tseem qis dua qhov tseem ceeb ntawm cov nti rau lub sijhawm ntev ntawm qhov kub thiab txias, nws yog ib qho tseem ceeb uas yuav tsum tau ua kom muaj kev nyab xeeb thiab kev cia siab rau thermal ua haujlwm rau UV-LED qhov chaw ntawm lub teeb. UV-LED lub teeb qhov chaw tswj qhov cua sov feem ntau yuav muab faib ua ob qhov txuas. Chip packing cov ntaub ntawv thiab cov txheej txheem ntim tau raug txhim kho nyob rau hauv lub teeb qhov chaw tsim khoom los txhim kho cov cua sov kom zoo.

Txawm li cas los xij, ntxiv cov hluav taws xob sab nrauv hauv kev siv engineering tuaj yeem txhim kho cov cua sov ua kom zoo dua. Cov qauv hluav taws xob muaj ntau yam, suav nrog hom fin, hom hloov hluav taws xob, hom hluav taws xob sib faib phaj, thiab hom micro-grooves, thiab lwm yam.

Txhawm rau kom tau txais qhov kub siab tshaj plaws ntawm UV-LED qhov chaw ntawm lub teeb uas tseem qis dua qhov tseem ceeb ntawm cov nti rau lub sijhawm txuas ntxiv nyob rau hauv qhov kub thiab txias, nws yog ib qho tseem ceeb rau kev sib koom ua ke kom muaj kev nyab xeeb thiab kev cia siab rau qhov ntsuas kub ntawm Ultraviolet.

UV-LED lub teeb qhov chaw tshav kub dissipation tsim tuaj yeem muab faib ua qib nti, qib ntim, thiab qib system. Lub hauv paus ntawm lub teeb hauv kev tsim khoom txiav txim siab thawj ob. Txoj kev kawm tsom mus rau ntawm daim ntawv no yog nyob rau ntawm qhov teeb meem kub dissipation, uas yog, optimizing kev tsim kho ntawm Ultraviolet lub teeb qhov chaw pab cua sov dab dej.

Qhov ntsuas kub ntawm LED yog dab tsi thiab vim li cas nws tseem ceeb?

Qhov kub thiab txias ntawm qhov taw tes qhov twg LED tuag ua tau raws li cov khoom nws tau teeb tsa. Qhov kev sib tshuam no feem ntau muaj cov cuab yeej kub tshaj plaws, ua rau nws tus nqi yog qhov qhia tau zoo ntawm kev ua kom sov dissipation efficiency. Conducive cua sov raws tau tsim rau hauv cov pob khoom LED niaj hnub kom hloov cov cua sov los ntawm kev sib tshuam mus rau qhov chaw solder. Lub pob LED txoj kev sib cuam tshuam nrog PCB lossis ib lub heatsink cais yog qhov chaw sib txuas ntawm cov khoom siv.

Internal thermal kuj ntawm LED ua hauj lwm raws li ib tug ntsuas ntawm efficiency ntawm sab hauv tshav kub txoj kev. Thermally hais lus, LED qhov zoo nce nrog txo qhov kub thiab txias. Tus nqi ntawm lub peev xwm kub yuav tsum tau nkag los ntawm tus kws tsim qauv tsim thaum tsim lub teeb pom kev zoo ntawm LED los ntawm kev tswj xyuas thermal. CFD cov neeg daws teeb meem yuav siv daim duab no los ntsuas qhov tseeb ntawm LED qhov kub thiab xyuas seb lub cuab yeej puas tau dhau los ntawm cov chaw tsim khoom-pom zoo rau sab saud. Kev sib tshuam kub hauv cov LEDs niaj hnub no feem ntau ncav cuag 100°C los yog siab dua. Nws tus nqi yog cuam tshuam los ntawm qhov kub thiab txias, qhov kub hloov pauv ntawm LED Circuit Court thiab nws ib puag ncig, thiab nti lub zog siv.

Thermal Design Factors

Txhua lub teeb LED yuav tsum tau ua kom txo qis thermal stability ntawm LED mus rau ib puag ncig huab cua kom cov LEDs txias. Conduction, convective, thiab thermal tawg yog cov Deb  hom cua sov dissipation uas yuav tsum tau coj mus rau hauv tus account thiab optimized thaum lub sij hawm tag nrho fixture tsim txheej txheem.

1. LED dav thiab configuration

Txhawm rau tsim cov qauv LED me me, cov neeg tsim qauv nquag xav kom luv luv ntawm Led ntawm PCB. Tab sis qhov no yuav ua rau lub zog thermal ntau dua, uas yuav txhim kho cov cua sov ntawm LEDs.

UV LED nquag muab qhov kev pom zoo nyob deb ntawm LEDs thiab qhia qhov ntsuas qhov kub thiab txias uas tuaj yeem xav tau thaum qhov kev ncua deb luv los ntawm ib qho tshwj xeeb. Cov kev tshawb fawb ntawm LED board layout tau qhia tias homogeneous thiab symmetrical nti kev npaj muab ib yam ntawm cov hluav taws xob tso zis seb lawv yog duab plaub, hexagon, los yog ncig.

2. Xaiv LED Module

Direct in-line packaging (DIP) LEDs thiab qhov tshiab tshaj plaws ntau daim chips ntawm boards (MCOB) LEDs tsuas yog ob peb ntawm ntau hom LEDs muaj. DIP LEDs feem ntau yog siv rau cov paib thiab tso saib ntawm cov khoom siv hauv tsev. Lawv txawv los ntawm lawv cov mos txwv daim ntawv.

SMD LEDs yog square semiconductors uas tuaj yeem tsim lub teeb hla tag nrho RGB spectrum.
