Qhov "Golden Range" ntawm Tsav Tsheb Voltage
Cov zis hluav taws xob ntawm tus tsav tsheb LED zoo li "khoom noj" rau lub teeb pom kev zoo - nws tsis tuaj yeem siab dhau lossis qis dhau! Feem ntau LED chips ua haujlwm ntawm 2-4V (piv txwv li, ib qho 3V dawb LED), tab sis tus tsav tsheb tso zis voltage feem ntau yog nyob rau hauv 12-24V ntau. Qhov no yog vim:
- Ntau LEDs nyob rau hauv series: Piv txwv li, 10 3V LEDs nyob rau hauv series yuav tsum tau 30V, tab sis nyob rau hauv kev xyaum, ib kauj ruam - down circuit yog siv, yog li ib tug tsav tsheb tso zis ntawm 24V yog ntau dua.
- Kev nyab xeeb margin: Tso cai rau 20% voltage fluctuation margin tiv thaiv kev puas tsuaj rau LEDs vim voltage instability.
- Kev ua kom zoo dua qub: 12-24V ntau qhov sib npaug sib kis kev poob thiab cov nqi tiv thaiv.
"Kev puas tsuaj Scene" ntawm Voltage Mismatch
Yuav ua li cas thaum koj siv qhov tsis ncaj ncees lawm voltage? Nws zoo li them lub xov tooj ntawm tes nrog 48V high voltage- qhov tshwm sim yog kev puas tsuaj!
- Overvoltage: Cov hlaws LED zoo li cov pa taws tau dhau mus, ua rau lub teeb nrawm nrawm, ua rau lub neej luv, thiab txawm tias hlawv.
- Undervoltage: Cov qij zoo li cov neeg ua haujlwm tsis muaj zog, tsis muaj qhov ci thiab flickering nquag. Kev siv sijhawm ntev - yuav ua rau tus neeg tsav tsheb puas tsuaj.
- Kev hloov hluav taws xob ntau dhau: Zoo ib yam li cov ntshav siab hloov pauv, qhov no ua rau cov xim kub hloov pauv hauv cov hlaws LED (xws li, lub teeb dawb tig liab).
- Tiag - piv txwv hauv ntiaj teb: Hauv ib lub chaw ua haujlwm siv tus tsav tsheb 36V los ua lub zog 12V LED sawb, 50% ntawm cov hlaws LED tsim cov pob dub tom qab 3 lub hlis.
Peb lub tswv yim rau xaiv tus neeg tsav tsheb kom tsis txhob muaj kev cuam tshuam:
- Tshawb xyuas LED hlaws tsis: Ua ntej, paub meej tias qhov ntsuas hluav taws xob ntawm LED hlaws (cim rau ntawm lub ntim / phau ntawv qhia). Tus tsav tsheb cov zis voltage yuav tsum sib npaug.
- Txheeb xyuas qhov ua haujlwm tam sim no: Siab- cov neeg tsav tsheb zoo yuav qhia cov zis tam sim no (xws li 300mA), uas yog qhov txhim khu kev qha ntau dua li tsuas yog kuaj xyuas qhov voltage.
- Tawm hauv chav rau kev hloov kho yav tom ntej: Nws raug nquahu kom xaiv tus tsav tsheb nrog qhov tso zis hluav taws xob me ntsis siab dua li qhov xav tau tam sim no (xws li siv 24V los tsav lub 12V LED sawb) los pab txhawb kev nce ntxiv ntawm cov hlaws LED.
