Chimodzi mwa zifukwa zazikulu zomwe zikuchulukirachulukira kutchuka kwa zowonetsera za LED ndikuti mphamvu zawo zikuyenda bwino. Zowonetserazi zimagwiritsa ntchito ukadaulo wa LED, womwe umagwira ntchito bwino kwambiri kuposa kuyatsa kwakale kwa incandescent, kuwalola kugwiritsa ntchito mphamvu zochepera 90%. Ichi ndichifukwa chake zowonetsera za LED zadzipangira mbiri ngati "zowonetsera mphamvu."
Kusanabwere zowonetsera za LED, zowonetsera za LCD zinkalamulira msika. Komabe, iwo anali odziwika chifukwa chogwiritsa ntchito mphamvu zambiri. Poyerekeza ndi zowonetsera za LED, zowonetsera za LCD zinali zanjala kwambiri komanso zodula kugwiritsa ntchito. Njira yopangira zowonetsera za LCD idapangitsanso kuti ikhale yokwera mtengo.
Kwa iwo omwe amaika patsogolo kukhazikika komanso kupulumutsa ndalama, kuyika ndalama pazowonetsera zopatsa mphamvu ndi chisankho chanzeru. Pochita kafukufuku wozama paziwonetserozi, mudzawona kuti amapereka phindu lanthawi yayitali ndipo ndi ndalama zanzeru.
1. Kodi Zowonetsera Zopanda Mphamvu Ndi Chiyani?
Zowonetsera zopanda mphamvu zimatengera zowonetsera za LED. Zowonetserazi zimadya mphamvu zochepa, zomwe zimapangitsa kuti zikhale zosavuta komanso zotsika mtengo poyerekeza ndi mitundu ina ya zowonetsera. Zowonetsera za LED zimadziwika ndi moyo wautali, nthawi zambiri zimakhala zotsalira za matekinoloje ena owonetsera.
Kupulumutsa mphamvu kwa zowonetsera za LED kumachokera kuukadaulo wawo wothandiza. Zowonetsera izi zimagwiritsa ntchito mphamvu zochepa, zomwe zimapangitsa kuti ndalama za magetsi zikhale zochepa. Ichi ndi chimodzi mwazifukwa zazikulu zomwe zowonetsera za LED zimakondedwa padziko lonse lapansi, m'mafakitale osiyanasiyana.
Zowonetsera zakunja za LED zatchuka kwambiri chifukwa cha mphamvu zawo zopulumutsa mphamvu. Pamaso pakuwonetsa kwa LED,ziwonetsero zazikulu zakunjaadagwiritsa ntchito magetsi ochulukirapo, zomwe zidapangitsa kuti pakhale ndalama zambiri. Ndiukadaulo wa LED, kugwiritsa ntchito mphamvu kumachepetsedwa kwambiri, makamaka poyerekeza ndi mitundu yakale yowonetsera ngati LCD.
2. Mawonekedwe a Mphamvu Zowonetsera Mphamvu
Zowonetsera zogwiritsira ntchito mphamvu sizimangokhudza teknoloji yatsopano ya LED; amapindulanso ndi zida zowonjezera komanso kapangidwe kabwino kabwino. Ngakhale zowonetsera zambiri za LED ndizopatsa mphamvu, pali mitundu ina yopangidwa ndi zina zambirizapamwamba zopulumutsa mphamvuMawonekedwe.
Zofunikira zazikulu zamawonekedwe a LED osagwiritsa ntchito mphamvu ndi monga:
● Kuchepetsa kupanga kutentha, kuchepetsa chiopsezo cha kutentha kwambiri
● Kutalika kwa moyo poyerekeza ndi zowonetsera zina
● Kutha kupirira nyengo komanso kusinthasintha kwa kutentha
● Kuwala kwakukulu kokhala ndi zofunikira zochepa zamagetsi
● Kusokoneza kwa ma electromagnetic kutsika
● Madalaivala opulumutsa mphamvu a IC, opereka 20-25% yowonjezera mphamvu zowonjezera mphamvu
● Kuchepetsa kutayika kwa magetsi ndi mapangidwe abwino a bolodi a PCB
● Avereji yogwiritsa ntchito mphamvu: 487 kWh pa sikweya ya module ya LED (50% kupulumutsa mphamvu)
3. Zinthu Zomwe Zimakhudza Kugwiritsa Ntchito Mphamvu Zowonetsera LED
Pankhani yochepetsa kugwiritsa ntchito mphamvu, pali zinthu zingapo zomwe zingakhudze kuchuluka kwa mphamvu zomwe chiwonetsero chanu cha LED chimagwiritsira ntchito. Ngakhale zowonetsera zowoneka bwino za LED zimagwiritsa ntchito mphamvu zambiri, zomasulira zopatsa mphamvu zimapangidwira kuti zithandizire izi kuti zigwiritsidwe ntchito mochepera.
● Mulingo Wowala
Kuwala kumakhudza kwambiri kugwiritsa ntchito mphamvu. Kuwala kokwera kumafunikira mphamvu zambiri, zomwe zimapangitsa kuti pakhale ndalama zambiri zamagetsi. Zowonetsera zowala, makamaka zomwe zimagwiritsa ntchito ukadaulo wakale wa LED kapena LCD, zimawononga mphamvu zambiri.
● Mtundu wa Zinthu
Mtundu wa zinthu zomwe zikuwonetsedwa zimakhudzanso kugwiritsa ntchito mphamvu. Makanema ndi makanema ojambula pamafunika mphamvu zambiri kuposa zolemba kapena zithunzi.
● Kusiyanitsa Mitundu
Mitundu yosiyanasiyana imafuna mphamvu zosiyanasiyana. Mwachitsanzo, mitundu yowala ngati yoyera imagwiritsa ntchito mphamvu zambiri, pomwe mitundu yakuda ngati yakuda imafuna zochepa.
● Pixel Pitch & Resolution
Mawonekedwe apamwambachithunzi cha pixel(kutanthauza kuti malo ambiri pakati pa ma pixel) amadya mphamvu zochepa. M'malo mwake, amawonetsa ndi ma pixel otsika komansokusamvana kwakukuluzimafuna mphamvu zambiri kuti zisungidwe zakuthwa kwa zithunzizo.
● Mtengo Wotsitsimula
Zowonetsa zotsitsimula mwachangu (momwe zosintha zosinthira pazenera) nthawi zambiri zimawononga mphamvu zambiri. Mwachitsanzo, mulingo wotsitsimutsa wa 240 Hz umagwiritsa ntchito mphamvu zambiri kuposa chiwonetsero cha 120 Hz.
● Kukula kwa Screen
Zowonetsera zazikulu zimadya mphamvu zambiri, kotero kusankha chowonetsera chaching'ono ndi njira imodzi yopulumutsira magetsi.
4. Momwe Mungachepetsere Kugwiritsa Ntchito Mphamvu Zowonetsera LED
Ngati mukufuna kupindula kwambiri ndi chiwonetsero chanu cha LED ndikuchepetsa kugwiritsa ntchito mphamvu, pali njira zingapo zomwe mungatsatire:
① Sinthani kuwala kwa chinsalu kukhala mulingo woyenera kwambiri ndi sensa yozungulira.
② Sankhani zowonetsa zokhala ndi ma pixel akulu akulu, chifukwa amagwiritsa ntchito mphamvu zochepa.
③ Zimitsani chiwonetserochi mukapanda kugwiritsa ntchito kuti mupewe kugwiritsa ntchito mphamvu mosayenera.
④ Gwiritsani ntchito njira "yopulumutsa mphamvu", yomwe imapangidwa muzowonetsera zamakono za LED.
⑤ Yang'anani zomwe opanga amapanga kuti muwonetsetse kuti mukugula zinthu zopanda mphamvu zenizeni.
⑥ Sankhani maziko amtundu wakuda, chifukwa amawononga mphamvu zochepa.
⑦ Khazikitsani mtengo wotsitsimutsa kukhala wocheperako kuti musagwiritse ntchito mphamvu zambiri.
Mapeto
Kuyika ndalama pazowonetsera zogwiritsa ntchito mphamvu kumapereka ndalama kwanthawi yayitali. Zowonetsera izi sizimangochepetsa kugwiritsa ntchito mphamvu komanso zimapereka ndalama zothandizira pochepetsa ndalama zamagetsi. Posankha zowonetsera zamagetsi za LED ndikukhala ndi zizolowezi zabwino zopulumutsira mphamvu, mudzawonetsetsa kuti ndalama zanu zikupita patsogolo.
Poyerekeza ndi zowonetsera zachikhalidwe za LED, mitundu yogwiritsa ntchito mphamvu imatha kuchepetsa kugwiritsa ntchito mphamvu mpaka 50%, kutsitsa bili yanu yamagetsi ndikukupatsani moyo wautali. Kumvetsetsa momwe chiwonetsero chanu chimagwiritsidwira ntchito komanso kugwiritsa ntchito njira zosungira mphamvu kukuthandizani kuti musunge ndalama zambiri komanso kuti mupindule kwambiri ndi chiwonetsero chanu.
