Yam ntxwv ntawmtsis tu ncua voltage fais fab mov
(1) Kev ntseeg siab
Tshwj xeeb tshaj yog zoo li kev tsav tsheb fais fab ntawm LED txoj kev teeb, nws tau teeb tsa ntawm qhov siab siab, ua rau kev saib xyuas tsis yooj yim thiab kim.
(2) High efficiency
LED yog cov khoom txuag hluav taws xob, thiab kev ua haujlwm ntawm kev tsav tsheb yuav tsum siab. Nws yog ib qho tseem ceeb heev kom dissipate cua sov los ntawm qhov sib txuas qhov twg cov khoom siv hluav taws xob tau nruab rau hauv lub luminaire. Kev ua tau zoo ntawm cov khoom siv hluav taws xob yog siab, nws lub zog siv me me, thiab cov cua sov tsim hauv lub teeb me me, uas kuj txo qhov kub ntawm lub teeb. Nws yog qhov zoo los ncua lub teeb lwj ntawm LED.
(3) Lub zog muaj zog
Lub zog qhov tseem ceeb yog qhov yuav tsum tau ntawm daim phiaj fais fab rau kev thauj khoom. Feem ntau, tsis muaj qhov yuav tsum tau ua rau cov khoom siv hluav taws xob qis dua 70 watts. Txawm hais tias lub zog qis ntawm ib qho khoom siv hluav taws xob nrog lub zog me me yuav muaj kev cuam tshuam me ntsis ntawm daim phiaj hluav taws xob, qhov loj ntawm cov teeb pom kev zoo siv thaum hmo ntuj thiab cov concentration ntawm cov khoom sib xws yuav ua rau muaj kuab paug loj rau hauv daim phiaj hluav taws xob. Rau 30- txog 40-watt LED tsav tsheb cov khoom siv hluav taws xob, nws tau hais tias tej zaum yuav muaj qee qhov kev xav tau ntawm lub zog hluav taws xob nyob rau yav tom ntej.
(4) Surge tiv thaiv
LED lub peev xwm los tiv thaiv surges yog qhov tsis zoo, tshwj xeeb tshaj yog nws muaj peev xwm tiv taus qhov hluav taws xob rov qab. Txhim kho kev tiv thaiv hauv cheeb tsam no kuj tseem ceeb. Qee lub teeb LED tau teeb tsa sab nraum zoov, xws li LED txoj kev teeb. Vim yog kev ua kom cov kab sib chaws thauj khoom thiab kev cuam tshuam ntawm xob laim, ntau qhov surges yuav cuam tshuam los ntawm kab sib chaws, thiab qee qhov surges yuav ua rau kev puas tsuaj rau LED. Yog li, nws tau txheeb xyuas tias kev tsav tsheb fais fab ntawm "Zhongke Huibao" yuav tsum muaj qee qhov tsis txaus ntawm kev tiv thaiv kev nce siab. Raws li kev hloov pauv ntawm cov khoom siv hluav taws xob thiab cov teeb, LED tsav lub zog yuav tsum muaj peev xwm tiv thaiv kev nkag mus ntawm kev nce siab thiab tiv thaiv LED los ntawm kev puas tsuaj.
(5) Kev tiv thaiv muaj nuj nqi
Ntxiv rau qhov kev tiv thaiv ib txwm ua haujlwm ntawm lub zog hluav taws xob, nws yog qhov zoo tshaj rau ntxiv LED qhov kub thiab txias tawm tswv yim rau qhov tso zis tam sim no los tiv thaiv qhov kub ntawm LED los ntawm kev kub siab dhau; nws yuav tsum ua raws li cov cai tswj kev nyab xeeb thiab cov kev cai electromagnetic compatibility.
Cov khoom siv hluav taws xob tsis tu ncuatuaj yeem muab faib ua rau pawg raws li cov qauv hauv Circuit Court
1. Pa transformer kauj ruam-down:
Qhov zoo ntawm cov khoom siv fais fab no yog nws qhov me me. Qhov tsis zoo yog tias nws hnyav hnyav thiab lub zog ua haujlwm tseem tsawg, feem ntau ntawm 45% thiab 60%. Vim tias qhov kev ntseeg siab tsis siab, nws tsis tshua siv.
