Kev Tiv Thaiv Kev Nyab Xeeb Thaum Lub Teeb LED -emitting Diode Ntim Txheej Txheem

1. Nyob rau hauv cov txheej txheem ntawm kev tsim khoom, kev cia khoom, kev thauj mus los thiab kev sib dhos ntawm LeD ntim kev nyab xeeb, cov cuab yeej, cov khoom siv, cov khoom siv, thiab cov neeg ua haujlwm tuaj yeem yooj yim tsim ntau txhiab qhov hluav taws xob vim muaj kev sib txhuam. Thaum cov LED nyob rau hauv kev sib cuag nrog cov nqi no, lub cev them nyiaj yuav tawm los ntawm LED 2. Vim lub siab resistivity ntawm cov ntaub ntawv semiconductor, lub sensory nqi generated los ntawm cov nti thaum lub sij hawm ntau lawm txheej txheem tsis yooj yim rau ploj. , tuaj yeem tsim hluav taws xob hluav taws xob siab. Qhov hluav taws xob no yuav ua kom muaj zog hluav taws xob puas tsuaj uas tsuas yog ntau pua mus rau txhiab lub rwb thaiv tsev sab hauv lossis tus PIN hauv cov rwb thaiv tsev sab hauv lossis PIN ntawm lub zog hluav taws xob kom tawg los ntawm LED. Cov txiaj ntsig zoo. Raws li pom hauv daim duab 2-2, qhov kev puas tsuaj ntawm LED sab hauv nti tshwm sim los ntawm qhov zoo li qub lossis hluav taws xob tso tawm. Feem ntau hais lus, qhov me me ntawm cov cuab yeej, qhov me me ntawm qhov hluav taws xob electrostatic koj tuaj yeem tiv taus, qhov hluav taws xob zoo li qub yuav hem nws. Kev puas tsuaj ntawm LED sab hauv nti tshwm sim los ntawm kev tso tawm hluav taws xob zoo li qub. Thaum lub sijhawm ua haujlwm, tus neeg teb xov tooj cov haujlwm yog qhov loj thiab nquag ua haujlwm, thiab muaj ntau yam kev sib cuag nrog cov khoom siv thiab cov khoom siv. Yog tias kev tiv thaiv zoo li qub tau ua raws li kev tiv thaiv electrostatic thaum lub sijhawm ua haujlwm, cov hluav taws xob zoo li qub yuav tsis raug xa tawm raws sijhawm, thiab LED tseem yuav ua rau LED loj heev. Table 2-1 teev cov voltage ntawm tib neeg lub cev. Raws li tuaj yeem pom los ntawm Table 2-1, nyob rau hauv cov txheej txheem nrog cov av noo tsawg, nws yog ib qho tseem ceeb heev uas yuav tsum tau ua qhov tsim nyog tiv thaiv zoo li qub thiab nruj me ntsis tswj kev puas tsuaj ntawm tib neeg lub cev voltage rau lub cuab yeej. Txawm li cas los xij, tib neeg hluav taws xob zoo li qub yog ib qho yooj yim tsis quav ntsej, thiab kev tiv thaiv electrostatic ntau dhau kuj yooj yim tsis quav ntsej. Thaum lub sij hawm tag nrho cov txheej txheem ntim LED, txhua tus neeg ua haujlwm uas ua cov txheej txheem ua haujlwm yuav tsum nco ntsoov khaws lub tswv yim ntawm kev tiv thaiv zoo li qub hauv siab.
