Cov khoom siv hluav taws xob hloov pauv (SMPS) yog cov khoom siv hluav taws xob tsim hluav taws xob uas ua rau lub zog muaj zog, ua kom pom kev zoo ntawm cov ntxaij vab tshaus LED niaj hnub hla ntau hom kev siv. Lawv efficiency, compactness, thiab meej lub zog xa khoom yog qhov tseem ceeb rau kev ua tau zoo thiab kev ntseeg tau.

Cov ntawv thov tseem ceeb:

Loj hom zaub: Chaw ntau pob Jumbotrons, sab nraum zoov billboards, thiab kev hais kwv txhiaj video phab ntsa vam khom rau siab zog SMPS. Cov ntxaij vab tshaus loj no xav tau lub zog loj, ruaj khov faib thoob plaws ntau txhiab tus qauv.

Sab Hauv Tsev Signage & Control Rooms: Cov chaw ntiav neeg ua haujlwm, kev tshaj tawm hauv khw muag khoom, kev tshaj tawm xov xwm, thiab lub luag haujlwm tseem ceeb hauv chav yees duab phab ntsa siv SMPS, txhim khu kev qha lub zog tseem ceeb rau kev ua haujlwm ntev thiab cov ntaub ntawv tseem ceeb.

Rental & Event Staging: Portable LED panels rau concerts, exhibitions, thiab cov rooj sib tham siv SMPS khoom plig rau lawv lub zog siab ceev (ua kom lub teeb yuag, qauv tsim) thiab muaj peev xwm los tswj cov kev sib txawv input voltages ntsib thoob ntiaj teb.

Fine Pitch & Direct View LED (DVLED): High-resolution nyob sab hauv cov lus qhia thiab nce kev ncaj qha saib LED TVs nyob ntawm SMPS kom ruaj khov.

Tsheb thauj mus los Hubs: Cov ntaub ntawv qhia hauv tshav dav hlau, chaw nres tsheb ciav hlau, thiab cov tsheb ciav hlau yuav tsum muaj SMPS muaj peev xwm ua haujlwm tau zoo hauv cov cheeb tsam nyuaj uas muaj peev xwm hloov tau.

Cov Khoom Siv Hluav Taws Xob & Cov Hluav Taws Xob:

Tsis tu ncua Voltage (CV) SMPS: Hom ntau tshaj plaws. Muab cov kev tswj nruj nruj DC tso zis hluav taws xob rau lub zog LED modules thiab cov khoom sib txuas.

Common tso zis voltage: 5v dc ua (rau cov logic sab hauv, tsav tsheb, qee qhov zoo-pitch modules), 12V DC lub zog (ntau heev rau ntau cov modules sab hauv tsev), 24V dc tso (feem ntau rau sab nraum zoov modules, ntev cable khiav), 48v dc ua (nrov nrov ntxiv rau cov khoom siv hluav taws xob siab thiab cov ntawv thov PoE vim qhov qis tam sim no / poob).

Constant Current (CC) Drivers: Thaum technically specialized power converters (feem ntau kuj hloov-hom raws li), cov no yog kev koom ua ke nyob rau hauv LED modules los yog txee. Lawv tau txais DC voltage (feem ntau 5V, 12V, 24V, lossis 48V los ntawm lub ntsiab CV SMPS) thiab xa cov tam sim no ncaj qha ncaj qha mus rau LED pixel hlua, kom ntseeg tau tias qhov ci ci thiab xim. Cov khoom siv hluav taws xob siab tuaj yeem siv CC tsav tsheb uas tau teeb tsa ze rau LEDs.

Fais fab dhau Ethernet (PoE) / PoE ++ Hloov: Rau cov ntaub ntawv me me lossis cov chaw tswj hwm hauv cov lus qhia loj, SMPS kev koom ua ke rau hauv PoE keyboards muab ob qho tib si cov ntaub ntawv thiab lub zog (feem ntau 48V DC) dhau ib lub cable.

Lub zog theem:

Lub zog xav tau sib txawv heev:

Cov cim hauv tsev me me: Kaum rau pua pua Watts.

High-Resolution Sab Hauv Tsev Phab Ntsa: Pua pua ntawm Watts mus rau ob peb Kilowatts (kW) ib square meter ncov brightness.

Sab nraum zoov Billboards/Stadium Screens: Kaum rau pua pua ntawm kW tag nrho lub cev muaj zog. High-power density SMPS (> 100W ib cubic nti) yog qhov tseem ceeb.

Xaus:

SMPS, feem ntau high-efficiency (> 90%) qhov hluav taws xob tsis tu ncua uas xa 5V, 12V, 24V, lossis nce 48V DC, tsim lub zog qaum qaum ntawm txhua qhov LED zaub. Ua haujlwm ua ke nrog cov tsav tsheb tam sim no, lawv ua kom muaj peev xwm ua kom muaj zog, ci ntsa iab, kev ntseeg tau, thiab kev pom kev ncaj ncees uas xav tau thoob plaws cov ntawv thov los ntawm cov hnab tshos loj rau cov spectacles.
