Kodi mukudziwa momwe mungawerengere kuchuluka kwa chiwonetsero chanu cha LED?
Zotsatsa zakunja zakhala zowulutsa zenizeni, ndipo mtengo wake wapadera wokhala ndi kanema wowala kwambiri komanso wowoneka bwino ndi wosasinthika.
Anthu ambiri amakhudzidwa ndi mphamvu ya chiwonetsero chakunja cha LED?Kapena mphamvu ya chiwonetsero chakunja cha LED imawerengedwa bwanji?
LeroMalingaliro a kampani YONWAYTECHifotokoza mwachidule mbali zimenezi.
Ndi kupita patsogolo kwaukadaulo, zotsatsa zotsatsa zakunja zikusintha nthawi zonse.
Omvera a wailesi, wailesi yakanema, manyuzipepala, ndi magazini akupitilizabe kusiyanitsa, zotsatsa zakunja zotsogola zowonetsa zakhala zowulutsa zenizeni zokhala ndi phindu lapadera palibe cholowa m'malo.
Choyamba, ponena za kukula kwa mphamvu ya zowonetsera zakunja za LED:
Pali mitundu iwiri ya mphamvu yowonetsera LED: nsonga ndi pafupifupi.
Zomwe zimatchedwa nsonga yamphamvu makamaka zimatanthawuza voteji nthawi yomweyo ndi mtengo wamakono poyambira ndi mphamvu pamene chinsalu chili choyera (choyera), pamene mphamvu yowonjezera ndi mphamvu yogwiritsidwa ntchito bwino.
Kodi chowonetsera chakunja cha LED chimakhala ndi mphamvu zotani?
Malingana ndi mitundu yosiyanasiyana yazinthu ndi opanga, mphamvu zamakono zamakono zowonetsera zamitundu yonse zimasiyana kuchokera ku 800W kufika ku 1500W pa lalikulu mita.
Kachiwiri, njira yowerengera mphamvu ya chiwonetsero chakunja chotsogolera:
P imayimira mphamvu, U imayimira voteji, ine ndikuyimira panopa.
Nthawi zambiri mphamvu zamagetsi zomwe timagwiritsa ntchito ndi 5V, magetsi ndi 30A ndi 40A;chiwonetsero chamtundu umodzi wotsogola ndi ma module a 8 ndi magetsi a 1 40A, ndi mawonekedwe amtundu wapawiri wotsogolera ndi ma module 6 mumagetsi a 1;
Chitsanzo chidzaperekedwa pansipa.
Ngati mukufuna kupanga masikweya mita 9 a chiwonetsero cha LED chamitundu iwiri cha P5, werengerani mphamvu yayikulu yofunikira.
Choyamba, kuwerengera chiwerengero cha 40A magetsi = 9 (0.244 × 0.488) / 6 = 12.5 = 13 magetsi (integers, kutengera muyezo waukulu), ndizosavuta, mphamvu yayikulu P = 13 × 40A× 5V= 2600W.
Mphamvu ya nyali imodzi = mphamvu ya nyali 5V * 20mA = 0.1W .
Mphamvu ya bolodi yowonetsera ya LED = mphamvu ya nyali imodzi * chigamulo (chiwerengero cha ma pixel opingasa * chiwerengero cha pixels ofukula) / 2;mphamvu yayikulu ya chinsalu = kusintha kwa chinsalu * chiwerengero cha magetsi pa chisankho * 0.1;Avereji yamphamvu = kusintha kwazenera * kuchuluka kwa magetsi pakusankha * 0.1/2;mphamvu yeniyeni ya chinsalu = mawonekedwe a skrini * chiwerengero cha magetsi pa chisankho * 0.1 / chiwerengero cha masikeni (4 scans, 2 scans, 16 scans, 8 scans, static).
Njira yowerengera mphamvu ya chiwonetsero cha LED ndikuwerengera kuchuluka kwa ma du, 0.3W / point * mfundo zonse ndi mphamvu zonse, ndipo mphamvu yayikulu imachulukitsidwa ndi gawo la 1.3.
Mphamvu yapakati ndi pafupifupi theka la mphamvu zambiri.
Ndipo chingwe chilichonse chamagetsi chiyenera kuwona kuti ndi makabati angati a LED omwe amayendetsa, ndi mfundo zingati zomwe zimawerengedwa, ndiye kuti mphamvu yonse imatha kuwerengedwa.
1. Zofunikira pazithunzi za LED:
Chiwonetsero chotsogolera panja (khalani kumwera ndi kuyang'ana kumpoto):> 4000CD/M2.
Chojambula chowongolera chamkati:> 800CD/M2.
Ma module otsogolera apakati:> 2000CD/M2.
2. Magawo atatu a mphamvu yowonetsera kunja kwa LED:
Mphamvu yapakati pa chinsalu = kusintha kwa chinsalu * chiwerengero cha magetsi pa chisankho * 0.1/2.
Mphamvu yayikulu ya chinsalu = mawonekedwe a chinsalu * kuchuluka kwa magetsi pakusankha * 0.1.,
Mphamvu yeniyeni ya chinsalu = kusintha kwa chinsalu * chiwerengero cha magetsi pa chisankho * 0.1 / chiwerengero cha zojambula (4 scans, 2 scans, 16 scans, 8 scans, static).…
Zomwe zili pamwambazi ndizofotokozera mwachidule za mphamvu yowonetsera kunja kwa LED ndi njira yowerengera, ndikuyembekeza kuti zidzakuthandizani.
Kuti mumve zambiri kuti mudziwe zambiri za LED zowonetsera chonde lolaniMalingaliro a kampani YONWAYTECHtimu mukudziwa.
