Yuav ua li cas los xaiv tus zoo tsav tsav?
Jul 27, 2018
Lub zog fais fab kev tsav tsheb yog qhov tseem ceeb ntawm cov khoom siv taws teeb taws. Qhov zoo tshaj plaws LED tsav tsheb fais fab mov tuaj yeem ua kom lub sij hawm ntev thiab ruaj khov ntawm tag nrho teeb pom kev zoo. Nws yog qhov tseem ceeb heev kom ua rau lub neej muaj teeb meem ntawm cov teeb pom kev zoo ntawm LED, txuag hluav taws xob thiab txo nqi. Tseem ceeb heev.
1. Tus tsav tsheb tsav LED yog dab tsi?
LED tsav fais fab yog ib qho hluav taws xob converter uas converts lub hwj huam mov mus rau ib qho kev siv hluav taws xob thiab tam sim no los tsav cov LEDs kom emit lub teeb. Feem ntau, cov tswv yim ntawm cov tsav tsheb muaj zog ntawm cov tsav tsheb muaj xws li muaj zog ua hluav taws xob ntau zog tam sim no (piv txwv li, coj mus muag zog), low-voltage direct current, high-voltage direct current, low-voltage high current alternating (xws li cov zis ntawm ib qho hluav taws xob hluav taws xob).
Nyob rau hauv cov nqe lus ntawm cov zis tam sim no, feem ntau cov tsav ntawm cov tsav hluav taws xob tsav hluav taws xob yog qhov chaw tam sim no uas hloov qhov voltage raws li cov LED pem taub hau poob siab hloov. Cov tub ntxhais ntawm lub hwj huam hluav taws xob ua muaj xws li kev tswj fais fab, ib qho kev sib dhos, ib qho khoom sib txuas (MOSfet), cov khoom tawm tswv yim, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov nyiam. Raws li qhov yuav tsum muaj ntawm ntau zaus, kuj muaj kev tawm tswv yim tiv thaiv kev tiv thaiv Circuit Court undervoltage Circuit Court, LED qhib Circuit Court tiv thaiv, overcurrent tiv thaiv Circuit Court thiab li ntawm.

2. Yuav ua li cas xaiv LED tsav fais fab?
(1) Kev ntseeg siab
Kev lag luam tau ruaj ntseg ntev ntev yog qhov tseem ceeb tshaj plaws rau cov khoom siv hluav taws xob. Hauv particular, tsav lub hwj chim ntawm LED txoj kev teeb yog ntsia nruab nrab ntawm qhov chaw siab tshaj, kev txij nkawm tsis phim, kev txij nkawm tseem loj, thiab kev ntseeg siab ua tau kom txo cov nqi txij nkawm.
(2) Kev ua haujlwm siab
LEDs yog cov khoom siv txuag hluav taws xob uas yuav tsum tau muaj kev ua haujlwm siab rau kev tsav tsheb. Nws yog ib qho tseem ceeb heev uas lub hwj huam tau muab tso rau hauv lub qhov rooj. Ntau dua qhov ua tau zoo ntawm lub hwj chim, lub zog me zog ntawm lub hwjchim, thiab qis dua qhov kub tsim hauv lub luminaire, yog li txo qhov kub ntawm lub luminaire, uas yog qhov tseem ceeb rau txoj kev pabcuam hauv lub neej ntawm cov LED .
(3) High power tau
Qhov zoo tshaj yuav yog qhov kab sib chaws ntawm txoj cai. Qhov kev siv hluav taws xob siab yuav zoo heev kom txo tau cov khoom ntawm lub hwj huam hluav taws xob. Piv txwv, nyob rau hauv nroog nights, qhov teeb meem ntawm lub teeb pom kev zoo yog loj, thiab cov nyiaj zoo sib xws li cov concentrated. High-power LED tsav tsheb yuav txo tau cov load ntawm lub hwj huam hluav taws xob, txo cov kev poob qis, thiab xyuas kom ruaj khov haujlwm ntawm cov khoom siv teeb pom kev zoo. .
(4) Tsav tsheb
Muaj ob txoj kev tsav tsheb tam sim no muaj: ib qho yog qhov hluav taws xob qhov hluav taws xob rau ntau qhov chaw tam sim no, thiab txhua qhov tam sim no qhov khoom siv fais fab rau txhua LED nyias. Nyob rau hauv no txoj kev, ua ke nrog saj zawg zog, ib qho tsis ua hauj lwm LED tsis cuam tshuam rau cov lag luam ntawm lwm cov LEDs; tus tod yog tus tsav tsheb ncaj qha rau cov khoom siv tam sim no, cov LEDs yog ua haujlwm hauv los yog hauv txoj kab sib luag, uas muaj qhov kom zoo dua ntawm tus nqi tsawg tab sis tsis zoo. Yuav kom daws tau ib qho tsis ua hauj lwm ntawm LED uas tsis cuam tshuam rau kev lag luam ntawm lwm cov LEDs. Cov ob hom coexist rau ib lub sijhawm, tab sis cov channel ntau qhov tam sim no tso zis fais fab mov yog qhov zoo tshaj plaws ntawm cov nqi thiab kev ua haujlwm, thiab ntau dua ntawm cov kev xav tau tiag tiag, uas yog kev taw qhia dav dav rau yav tom ntej.
(5) Kev tiv thaiv kom zoo
Muaj peev xwm ntawm LEDs mus tiv thaiv surges yog kuj txom nyem, tshwj xeeb tshaj yog tawm tsam rov qab muaj peev xwm voltage. Sab nraum zoov LED khoom, xws li LED teeb teeb, vim pib ntawm cov kab sib tsoo thiab nrhiav kom pom ntawm xob laim, yuav cuam tshuam ntau yam los ntawm kab sib chaws, thiab qee qhov surges yuav ua kev puas tsuaj rau cov LEDs, kom lub hwj huam thiab cov roj teeb nquag hloov. Yog li no, kev tiv thaiv zoo tiv thaiv kuj yog ib qho yuav tsum muaj rau tus tsav tsheb zoo LED.
(6) Kev tiv thaiv ua haujlwm
LED tsav lub hwj chim yuav tsum tau muaj kev tiv thaiv txog kev tiv thaiv, xws li kev tiv thaiv kev tiv thaiv, kev tiv thaiv luv luv, kev tiv thaiv overprurrent / overvoltage, thiab lwm yam., Los xyuas kom meej tias cov teeb pom kev zoo hauv cov khoom ua haujlwm muaj kev nyab xeeb thiab muaj zog thaum muaj xwm txheej ceev.
