Yog hais tias lub tsav hluav taws xob muaj cov kauj ruam ntawm kauj ruam, kev txhim kho thiab lim ntxiv ntxiv rau DC qhov hluav taws xob txuas hluav taws xob tam sim no lossis cov hluav taws xob hloov hluav taws xob txuas ntxiv nrog rau cov hluav taws xob tsis kam, nws kuj yuav tsum siv ntau lub zog siv hluav taws xob. Yog li no, qhov ua tau zoo ntawm ob hom kev tsav lub zog tsis zoo li tsis muaj lub siab nyob rau hauv lub premise ntawm yeej txaus siab rau qhov tso zis tawm tam sim no. Tus qauv tsim raug yog kev siv hluav taws xob hloov mus ua hluav taws xob lossis kev siv hluav taws xob ntau kom tsav cov LEDs. Siv cov txheej txheem ob saum toj saud tuaj yeem ua rau lub zog Circuit Court tseem muaj qhov hloov dua siab tshiab ntawm lub zog thaum tswj kom zoo cov zis tam sim no cov yam ntxwv.

Cov teeb pom kev hauv peb lub teb chaws ib txwm txais hom ntawm HID lub teeb pom kev ntxiv ntxiv rau lub hauv paus thiab lub pob hauv lub siab, txawm tias hom no muaj cov teeb meem ntawm kev siv hluav taws xob tsawg thiab stroboscopic. Thaum LED teeb hluav taws xob nrog hluav taws xob tsav hluav taws xob tau siv nyob rau hauv kev teeb pom kev zoo sab nraum zoov, ib qho tseem ceeb uas tsim kev hem thawj lawv cov yas yog teeb meem hluav taws xob.

Raws li peb txhua tus paub, xob laim nyob saum ntuj tau tshaj tawm lub xov tooj cua sab nrauv, thaum lub zog hluav taws xob ntawm cov kab teeb hla kev teeb pom kev zoo tau txais wireless. Cov xov tooj cua tshuab hluav taws xob tawm los ntawm cov hluav taws xob zoo ib yam los ntawm ob lub zog hluav taws xob yog cov sib txuam sib cuam tshuam rau cov lus qhia rau lub tshuab tsav. Qhov cuam tshuam zoo li no-cuam tshuam muaj peev xwm ncav cuag ntau pua ntawm ntau txhiab mus txog ntau txhiab ntawm qhov hluav taws xob mus rau hauv av, thiab nws yooj yim kom tawg rau hauv lub tshuab hluav taws xob. EMC qhov pib muaj peev xwm lossis qhov hluav taws xob me me rau hauv av (rau lub plhaub) tuaj yeem tsim kev puas tsuaj rau lub tshuab hluav taws xob.

Ntxiv rau qhov no, txij li kuv lub teb chaws txoj kab hluav taws xob txoj kab hluav taws xob yog peb-plaub plaub-xaim hluav taws xob nruab nrab kab hluav taws xob hauv av polar fais fab mov, nyob rau txhua ntu ntawm ob txoj kab hluav taws xob xa xov hluav taws xob, thaum lub sijhawm xov tooj cua yoj ntawm xob laim, ob lub zog cov kab khoom sib txuas yog txuas rau hauv av. Cov cuam tshuam tam sim ntawd sib txawv thiab ib qho kev sib txawv ntawm cov kev cuam tshuam voltage tsim tawm ntawm ob txoj hlua hluav taws xob. Qhov no tam sim no txawv ntau hom kev cuam tshuam voltage tseem tuaj yeem ncav cuag ntau pua ntawm cov hluav taws xob mus rau ntau dua 3000 volts. Qhov voltage no feem ntau tsoo lub zog txuas hluav taws xob diode thiab luam tawm cov hluav taws xob ntawm cov tsav hluav taws xob. Txhawm rau kom tswj qhov hluav taws xob sib txawv ntawm cov hluav taws xob ntawm qhov sib txawv ntawm cov kab hluav taws xob ntawm lub rooj tsav xwm hauv Circuit Court, tus maub los LED kuj tseem yuav ua kom puas lub tshuab tsav hluav taws xob.

Yuav kom daws tau qhov teeb meem no, tus hloov pauv ceev nrawm yuav tsum txuas nrog cov tswv yim sab kawg ntawm LED tsav Circuit Court kom ntseeg tau tias qhov paug tawm ntawm cov sib txawv ntawm cov kev cuam tshuam.
