Taw qhia txog Ntau Yam Kev Pab Hluav Taws Xob Kev Xeem Hluav Taws Xob
(1) Tshawb xyuas seb cov foraments ntawm qhov muag teeb thiab fluorescent raug hlawv tawm. Thaum zoo tib yam dog dig iav los yog xim tsis muaj teeb meem thiab cov tshuaj fluorescent rau kev siv tsev neeg tsis tuaj yeem pom ncaj qha rau cov ntsiab lus (tungsten hlau) sab hauv tau hlawv tawm. Kev txiav txim tsuas yog ua los ntawm cov hauv kev xws li kev ntsuas ntau. Tab sis raws li qhia hauv daim duab 10, ib txhais tes muaj peev xwm tuav ib qho hluav taws xob lub teeb (sau tus ntiv tes tuav lub teeb (lossis tus ntiv tes fluorescent) Yog tias LED sab hauv kev ntsuam xyuas lub teeb, nws txhais tau tias cov ntsiab lus tsis tau raug hlawv, thiab lub teeb txawb fluorescent) yog qhov zoo; Yog tias LED sab hauv tus cwj mem tsis taws, nws qhia tau tias lub teeb lub teeb ci ntsa iab (lossis tuaj yeem raug kaw thiab hloov nrog lub tshiab. Qhov no ntawm kev pom tias cov ntsiab lus tau hlawv tawm yog yooj yim thiab nrawm, thiab muaj txiaj ntsig zoo rau kev daws teeb meem teeb pom kev zoo.
(2) Kuaj xyuas yog tias muaj qhov hluav taws xob hluav taws xob muaj hluav taws xob. Cov khoom siv hluav taws xob yuav tsum tswj cov hluav taws xob zoo nrog rau ob lub Hower Plugent yuav tshwm sim thaum tib neeg lub cev kov cov khoom siv hluav taws xob siv hluav taws xob. Cov txheej txheem qhia nyob rau hauv daim duab ll yog siv cov cwj mem ntsuas kom pom tias cov plhaub sab nraud ntawm cov hlau sib txuas. Pinch lub zog hluav taws xob ntawm cov hlau khi nrog ib sab tes nrog rau lwm tes (nco ntsoov tias cov ntiv tes xoo hluav taws xob nrog cov hlau plhaub ntawm cov hlau. Yog tias LED sab hauv qhov ntsuas qhov ntsuas tsis taws, nws qhia tau tias cov kev ua tau zoo ntawm cov hlau plhaub ntawm cov hlau taub hau ntawm cov hlau taub hau thiab cov hluav taws xob sab hauv yog qhov zoo; Yog tias qhov ntsuas hauv qhov ntsuas ntawm tus cwj mem taws teeb, nws qhia tau tias muaj qhov tshwm sim tsis txaus siab nruab nrab ntawm cov hlau sab hauv thiab cov plhaub hlau. Nws yuav tsum tau siv tom qab daws teeb meem soldering hlau. Txoj kev ntsuas rau lwm cov khoom siv hluav taws xob yog tib yam.
(3) pom cov txuas ntxiv ntawm coils xws li inductors thiab transformers. Raws li pom hauv daim duab 12, tuav ib qho ntsuas cwj mem (nco ntsoov tias koj cov ntiv tes yuav tsum muaj kev sib chwv nrog tus cwj mem ib leeg ntawm cov coil xws li inductor lossis transformer. Dhuav lwm qhov kawg ntawm lub kauj nrog lwm txhais tes. Yog tias sab hauv LED ntawm tus cwj mem ntsuas teeb, nws txhais tau tias cov coil tau txuas nrog; Yog hais tias sab hauv lub teeb-emitting diode tus cwj mem tsis teeb, nws qhia tau tias lub kauj tau qhib sab hauv.
(4) Txiav txim siab cov polarity ntawm Diode. Raws li pom hauv daim duab 13, ncaj qha ib qho kawg ntawm cov diode nrog koj txhais tes, kov tus cwj mem uas ntsuas koj sab tes, thiab siv cov tshuaj ntsuam xyuas kom kov lwm qhov kawg ntawm Diode. Yog hais tias sab hauv lub teeb-emitting diode ntawm ntsuas cwj mem emits lub teeb, nws txhais tau tias ib qho kawg ntawm cov ntsuas cwj mem sib tw yog qhov tsis zoo; Yog tias LED tsis emit teeb, nws txhais tau tias qhov xwm txheej yog qhov sib txawv. Tes tuav ib qho kawg ntawm Diode ntawm no yog sib npaug rau cov kev sojntsuam dub uas siv los ntawm Ohm ntau yam kev sojntsuam yog sib npaug rau cov kev sojntsuam liab. Tau muab tsab cai lij choj no, ib qho tseem siv tau tus cwj mem ib ce tau los txiav txim siab seb puas tau qhib, nrog rau cov tub rog, koj, thiab lwm yam khoom siv. Cov neeg nyeem tuaj yeem siv lawv lub hlwb thiab tes los piav qhia txog cov hau kev tshwj xeeb, uas yuav tsis raug piav qhia ntawm no. Vim kev siv ob txhais tes es tsis txhob ntsuas kev ntsuas, nws yooj yim dua ua haujlwm ua haujlwm ntau dua li tus multimeter.
