Kev cuam tshuam ntawm ib puag ncig yam ntawm lub neej ntawm LED zaub
1. Qhov cuam tshuam ntawm qhov kub thiab txias ntawm lub neej ntawm LED zaub
Qhov tsis ua hauj lwm tus nqi ntawm ib yam khoom thaum lub sij hawm nws cov kev pab cuam lub neej thiab tsuas yog nyob rau hauv tsim nyog ua hauj lwm tej yam kev mob yog tsawg heev. Raws li cov khoom siv hluav taws xob sib xyaw ua ke, LED zaub yog tsim los ntawm pawg tswj hwm, hloov hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam, uas txuas nrog cov khoom siv hluav taws xob. muaj pes tsawg leeg, thiab lub neej ntawm tag nrho cov no yog ze ze rau kev khiav hauj lwm kub. Yog hais tias qhov tseeb ua hauj lwm kub tshaj qhov kev siv ntau yam ntawm cov khoom, tsis tsuas yog cov kev pab cuam lub neej yuav luv luv, tab sis cov khoom nws tus kheej kuj yuav puas.
2. Kev cuam tshuam ntawm plua plav ntawm lub neej ntawm LED zaub
Txhawm rau ua kom lub neej ntev tshaj plaws ntawm LED cov lus qhia, kev hem thawj ntawm cov plua plav tsis tuaj yeem tsis quav ntsej. Ua hauj lwm nyob rau hauv ib puag ncig plua plav, txij li lub rooj tsavxwm luam ntawv absorbs plua plav, qhov tso tawm ntawm cov plua plav yuav cuam tshuam rau lub tshav kub dissipation ntawm cov khoom siv hluav taws xob, uas yuav ua rau qhov kub thiab txias ntawm cov khoom yuav nce siab, thiab tom qab ntawd cov thermal stability yuav txo qis los yog ua rau kom tawg, yuav ua rau burnout nyob rau hauv mob hnyav. . Tsis tas li ntawd, cov plua plav tuaj yeem nqus cov dej noo, corrode hluav taws xob hauv hluav taws xob, thiab ua rau tsis ua haujlwm luv luv. Txawm hais tias cov plua plav ntim me me, qhov teeb meem rau cov khoom tsis tuaj yeem kwv yees. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ntxuav tsis tu ncua kom txo qhov tshwm sim ntawm kev ua tsis tiav. Thaum ntxuav cov plua plav hauv cov zaub, nco ntsoov txiav lub hwj chim thiab ua haujlwm nrog kev saib xyuas.
3. Kev cuam tshuam ntawm cov av noo ntawm lub neej ntawm LED zaub
Txawm hais tias yuav luag txhua qhov LED zaub tuaj yeem ua haujlwm ib txwm nyob hauv ib puag ncig nrog cov av noo ntawm 95 feem pua, cov av noo tseem yog qhov tseem ceeb cuam tshuam rau cov khoom lag luam. Cov pa ntub dej yuav nkag mus rau hauv cov khoom siv IC los ntawm kev sib txuas ntawm cov khoom ntim thiab cov khoom sib txuas, ua rau cov khoom siv hluav taws xob sab hauv raug oxidized thiab corroded, thiab qhov kub siab thaum lub vuam txheej txheem yuav ua rau cov roj moist nkag mus rau hauv IC kom sov. thiab nthuav kom tsim kom muaj siab, kom cov yas raug tshem tawm ntawm IC. Kev sib cais sab hauv (delamination) ntawm qhov tuag los yog leadframe, xaim daim ntawv cog lus kev puas tsuaj, tuag kev puas tsuaj, sab hauv cov kab nrib pleb thiab cov kab nrib pleb txuas mus rau qhov chaw tiv thaiv, lossis txawm tias cov khoom bulging thiab popping, tseem hu ua "popcorn", uas yuav ua rau kev sib dhos kho lossis txawm. seem. Qhov tseem ceeb tshaj, cov tsis pom thiab latent tsis xws luag yuav muab tso rau hauv cov khoom, ua rau muaj teeb meem nrog kev ntseeg siab ntawm cov khoom. Kev txhim kho kev ntseeg siab nyob rau hauv qhov chaw ntub dej muaj xws li kev siv cov ntaub ntawv pov thawj noo noo, dehumidifiers, thiab cov ntaub thaiv npog.
4. Kev cuam tshuam ntawm cov roj corrosive rau lub neej ntawm LED zaub
Cov av noo thiab qab ntsev ib puag ncig tuaj yeem ua rau qhov kev ua haujlwm tsis zoo vim lawv ua rau muaj kev cuam tshuam ntawm corrosion ntawm cov hlau, nrog rau cov galvanic hlwb, tshwj xeeb tshaj yog thaum cov hlau tsis sib xws tuaj rau hauv kev sib cuag. Lwm qhov ua rau muaj kev puas tsuaj ntawm cov av noo thiab qab ntsev yog qhov tsim ntawm cov yeeb yaj kiab ntawm qhov chaw ntawm cov khoom tsis yog xim hlau uas degrade lub insulating thiab dielectric zog ntawm cov ntaub ntawv no, tsim kom muaj txoj hauv kev. Kev nqus dej los ntawm cov ntaub ntawv insulating tuaj yeem ua rau muaj qhov nce ntawm cov khoom siv ntau yam thiab dissipation yam. Kev txhim kho kev ntseeg siab nyob rau hauv huab cua huab cua thiab qab ntsev muaj xws li kev siv hermetic seals, cov ntaub ntawv noo noo barrier, dehumidifiers, tiv thaiv coatings / npog, thiab txo kev siv cov hlau sib txawv.
5. Kev cuam tshuam ntawm hluav taws xob hluav taws xob ntawm lub neej ntawm LED zaub
Kev cuam tshuam ntawm xov tooj cua zaus hluav taws xob rau cov tshuab hluav taws xob feem ntau yog los ntawm ob qhov chaw. Ib txoj hauv kev yog rau cov suab nrov hluav taws xob cuam tshuam los ntawm cov hluav taws xob hluav taws xob kom khiav ncaj qha rau hauv qhov system. Cov kev sim qhia tau hais tias thaum lub zog teb mus txog 5V / m, lub kaw lus yuav twv yuav raug hu mus tsis ncaj ncees lawm, thiab kev cuam tshuam ntawm electromagnetic txaus los hloov tus nqi ntawm CPU program counter PC, ua rau lub microcomputer "dhia" ntawm qhov kev ua yuam kev. , tshwj xeeb tshaj yog rau cov teeb liab me me. Lub cim xeeb tsis tuaj yeem ua haujlwm ib txwm thaum lub zog ua haujlwm yog 15V / m. Lwm txoj hauv kev ntawm RF radiated cuam tshuam yog los ntawm kev qhia txog cov khoom siv fais fab. Cov kab sib kis ntawm cov ncej sab nrauv yog sib npaug rau cov kav hlau txais xov, uas qhia txog kev cuam tshuam hluav taws xob rau hauv lub cev. Thaum muaj kev cuam tshuam loj heev, lub zog ntawm qhov system nws tus kheej tuaj yeem raug hlawv.
6. Lub zog ntawm kev co ntawm lub neej ntawm LED zaub
Cov khoom siv hluav taws xob feem ntau raug cuam tshuam rau ib puag ncig kev poob siab thiab kev co thaum siv thiab kev sim. Qhov ib puag ncig no tuaj yeem ua rau lub cev puas tsuaj rau cov khoom thiab cov khoom siv thaum muaj kev ntxhov siab los ntawm cov khoom siv deflection ntau tshaj qhov tso cai ua haujlwm ntawm cov khoom siv.
7. Kev cuam tshuam ntawm kev thauj khoom ntawm lub neej ntawm LED zaub
Txawm hais tias nws yog ib qho kev sib xyaw ua ke, lub raj LED lossis lub zog hloov hluav taws xob, txawm tias nws ua haujlwm raws li qhov ntsuas ntsuas los yog tsis, lub nra kuj yog qhov tseem ceeb cuam tshuam rau lub neej. Vim hais tias ib qho kev tivthaiv muaj lub sijhawm ua rau qaug zog, noj cov khoom siv hluav taws xob ua piv txwv, cov khoom siv hluav taws xob tuaj yeem tso tawm 105% ~ 135 feem pua ntawm lub zog, tab sis yog tias cov khoom siv hluav taws xob ua haujlwm nyob rau hauv lub siab load rau lub sijhawm ntev, nws yuav. inevitably ua kom cov laus ntawm lub zog hloov pauv. Tau kawg, qhov hloov hluav taws xob hloov pauv tsis tas yuav poob tam sim, tab sis nws yuav txo nws txoj sia sai.
Txheej txheem cej luam
Nws tuaj yeem pom los ntawm kev cuam tshuam ntawm ntau yam ib puag ncig ib puag ncig saum toj no ntawm cov khoom lag luam kev ntseeg tau tias txhua qhov xwm txheej ib puag ncig tau ntsib los ntawm cov khoom lag luam thaum nws lub neej voj voog yuav tsum xav txog hauv cov txheej txheem tsim. Qhov no ua kom ntseeg tau tias ib puag ncig muaj zog txaus tau muab tso rau hauv kev tsim kev ntseeg tau. Yog lawm, kev txhim kho kev siv ib puag ncig ntawm cov khoom thiab kev saib xyuas tsis tu ncua ntawm cov khoom tuaj yeem tsis tsuas yog tshem tawm cov teeb meem zais hauv lub sijhawm, tab sis kuj pab txhim kho kev ntseeg siab ntawm cov khoom thiab ua kom lub neej nruab nrab ntawm cov khoom.
