Pamene ukadaulo wa LED ukupitilirabe kusinthika, Zikwangwani za LED zikugwira ntchito yofunika kwambiri pazakuwonetsa zotsatsa komanso kufalitsa zidziwitso. Chifukwa cha mawonekedwe awo apadera komanso mawonekedwe osinthika ogwiritsira ntchito, mabizinesi ochulukirachulukira ndi amalonda apanga chidwi kwambirimtengo wa chiwonetsero chazithunzi za LED. Nkhaniyi ipereka kusanthula kwatsatanetsatane kwamitengo ya zikwangwani za LED kuti zikuthandizeni kumvetsetsa mtengo wake ndikukupatsirani chitsogozo chokuthandizani kupanga zisankho zogulira mwanzeru.
1. Kodi Mitengo ya Zikwangwani za LED Ndi Chiyani - Quick Guide
Nthawi zambiri, mitengo wamba yazithunzi za LED imachokera500 mpaka 2000 USD. Mtengo wake umasiyanasiyana kutengera mtundu wa ma diode a LED, kukwera kwa ma pixel, kuchuluka kwa zotsitsimutsa, ndi zina zotero. Mwachitsanzo, pansi pa mikhalidwe yofanana ya kukula kwa pixel ndi kukula kwake, chiwonetsero chazithunzi cha LED chokhala ndi ma diodi a Osram LED chikhoza kukhala chokwera mtengo kuposa chokhala ndi San'an Optoelectronics LED diode. Mitundu yosiyanasiyana ya nyali zowonetsera zazithunzi za LED zimasiyana mtengo wake chifukwa cha kusiyana kwa khalidwe, kachitidwe, ndi malo amsika, zomwe zimadziwonetsera zokha.
Ukadaulo wa LED umapereka kuwala, kusiyanitsa, ndi mawonekedwe. Mitengo yowonetsera positi ya LED imachokera ku$ 1,000 mpaka $ 5,000 kapena kupitilira apo.
Nazi zina zomwe zimakhudza mtengo wazithunzi za LED
1.1 IC Drive
Kuyendetsa kwa IC ndi gawo lofunikira pazithunzi zazithunzi za LED, zomwe zimakhudza mwachindunji mawonekedwe ndi mtengo. Magalimoto apamwamba a IC amatha kuwongolera bwino komanso zowonetsera zokhazikika, kuchepetsa kulephera komanso kukulitsa moyo. Kusankha ma drive a IC abwino sikuti kumangowonjezera kulondola kwamtundu komanso kuwala kofanana komanso kumachepetsanso mtengo wokonza. Ngakhale ndizokwera mtengo, zoyendetsa za IC zapamwamba zimakupulumutsirani ndalama zolipirira pakapita nthawi ndikuwonjezera luso la ogwiritsa ntchito.
1.2 Mikanda ya Nyali ya LED
Mtengo wa mikanda ya nyali ya LED muzithunzi za LED nthawi zambiri ndi chimodzi mwazinthu zazikulu zomwe zimafunikira pamitengo yonse.
Mikanda ya nyale ya Premium ya LED imapereka kuwala kwakukulu, kukhathamiritsa kwamtundu wabwino, komanso moyo wautali, zomwe ndizofunikira kwambiri panja komanso malo owonekera kwambiri. Mitundu yodziwika bwino ya nyali ya LED yomwe imapezeka pamsika ikuphatikizapo Samsung, Nichia, Cree, etc., omwe nyali zawo za LED zimagwiritsidwa ntchito kwambiri pazowonetsera zapamwamba za LED chifukwa cha khalidwe lawo komanso kukhazikika.
1.3 Zithunzi za LED
Zida za kabati yowonetsera za LED zimakhala ndi chitsulo, aluminium alloy, magnesium alloy, ndi aluminium die-cast. Zida zosiyanasiyana sizimangodziwa kulemera kwa chiwonetserocho komanso zimakhudzanso mtengo wake.
Kulemera kwa makabati owonetsera digito a LED kumasiyana kwambiri kutengera zinthu. Makabati achitsulo nthawi zambiri amakhala olemera kwambiri, olemera pafupifupi ma kilogalamu 25-35 pa lalikulu mita imodzi, oyenera pazochitika zomwe zimafuna mphamvu zambiri; makabati a aluminiyamu aloyi ndi opepuka, olemera pakati pa 15-20 kilogalamu pa lalikulu mita, amagwiritsidwa ntchito kwambiri m'ma projekiti ambiri; makabati a aloyi a magnesium ndi opepuka kwambiri, olemera pafupifupi ma kilogalamu 10-15 pa lalikulu mita imodzi, oyenera kugwiritsa ntchito zida zapamwamba zomwe zimafuna kuchepetsa thupi; makabati opangidwa ndi aluminiyamu amakhala pakati, olemera pafupifupi ma kilogalamu 20-30 pa lalikulu mita, akupereka mphamvu zabwino komanso kukhazikika. Kusankha zipangizo zoyenera kumafuna kulingalira mozama za zosowa za polojekiti ndi bajeti.
1.4 PCB Board
Mtengo wa matabwa PCB makamaka amachokera ku mtundu wa zipangizo ndi chiwerengero cha zigawo.
Zida zodziwika bwino za PCB zimaphatikizapo FR-4 fiberglass circuit board ndi copper-clad laminates (CCL), ndi CCL zambiri kuposa FR-4 fiberglass circuit board. Ma board ozungulira a FR-4 fiberglass ndiochulukira komanso otsika mtengo, pomwe CCL imachita bwino pakukhazikika komanso kutumiza ma siginecha.
Kuphatikiza apo, kuchuluka kwa zigawo mu ma module owonetsera a LED kumagwirizana bwino ndi mtengo. Magawo ochulukirapo omwe gawoli limakhala nawo, kutsika kwake kumachepetsa, komanso kumapangitsa kuti pakhale zovuta kupanga. Ngakhale kuti mapangidwe amitundu yambiri amawonjezera ndalama zopangira, amathandizira kwambiri kukhazikika ndi kudalirika kwa zowonetsera za LED, makamaka zofunika paziwonetsero zazikuluzikulu komanso zowoneka bwino za LED. Choncho, posankha ma modules owonetsera ma LED, kusankha kwa zigawo ndi zipangizo zidzakhudza mwachindunji mtengo, kudalirika, ndi ntchito ya zikwangwani za LED.
1.5 Magetsi a LED
Mphamvu yamagetsi ya LED, monga gawo lalikulu la zikwangwani za LED, imakhala ndi zotsatira zosatsutsika pamitengo. Magetsi apamwamba kwambiri a LED ali ndi mphamvu zomveka bwino komanso zotulutsa zamakono, kuwonetsetsa kuti ma diode a LED azigwira ntchito mokhazikika, amachepetsa kuwonongeka, motero amatalikitsa moyo wautumiki, zomwe zimawapangitsa kukhala okwera mtengo. Pakadali pano, mphamvu yamagetsi yamagetsi iyenera kufanana ndi mawonekedwe ndi mawonekedwe ogwiritsira ntchito chiwonetsero chazithunzi za LED. Mphamvu zamagetsi zamphamvu komanso zogwira mtima ndizokwera mtengo. Mwachitsanzo, zikwangwani zakunja za LED zimafunikira mphamvu zamagetsi zopanda madzi kuti zigwirizane ndi malo ovuta komanso ntchito zolemetsa kwambiri, zomwe zimawonjezera mtengo wazithunzi zonse za LED poyerekeza ndi magetsi wamba pazithunzi zazing'ono zamkati za LED. Chowonetsera chojambula cha LED chokhala ndi 640192045mm nthawi zambiri chimakhala ndi mphamvu zambiri zogwiritsa ntchito pafupifupi 900w pa mita imodzi imodzi ndikugwiritsa ntchito mphamvu pafupifupi 350w pa mita imodzi.
2. Kodi mtengo wa zikwangwani za LED umawerengedwa bwanji?
Kukula kofanana kwa chojambula cha LED nthawi zambiri ndi 1920 x 640 x 45 mm.
Ngati mukufuna kusintha kukula kwake, ingolumikizanani ndi wopanga. Chiwonetsero cha LED cha RTLED chimathandizira kusanja kosasinthika, kukulolani kuti mupange malo owonetsera malinga ndi malo anu.
2.1 LED Control System
Masinthidwe ndi kuchuluka kwa makhadi olandila ndi makhadi otumiza ndizinthu zofunikira pamitengo yazithunzi za LED.
Nthawi zambiri, ngati positi ya LED ndi yaying'ono, monga 2 - 3 masikweya mita, mutha kusankha khadi yotumiza ya Novastar MCTRL300 yophatikizidwa ndi makhadi olandila a MRV316. Khadi lotumiza limatenga pafupifupi 80−120 USD, ndipo khadi iliyonse yolandira imawononga pafupifupi 30−50 USD, yomwe imatha kukwaniritsa zofunikira zoyendetsera ma siginecha ndikuwonetsa zowongolera pamtengo wotsika kwambiri.
Pazithunzi zokulirapo za P2.5, mwachitsanzo, kupitilira masikweya mita 10, ndibwino kugwiritsa ntchito khadi yotumiza ya Novastar MCTRL660 yokhala ndi makadi olandila a MRV336. Khadi lotumiza la MCTRL660, lomwe lili ndi kuthekera kolimba kosinthira deta komanso mawonekedwe angapo, limawononga pafupifupi 200−300 USD, pomwe khadi lililonse la MRV336 ndi pafupifupi 60−80 USD. Kuphatikiza uku kumatsimikizira kufalikira kokhazikika komanso kothandiza kwa ma siginecha akuluakulu.
Ndalama zonse za makadi olamulira zidzakwera kwambiri ndi kuwonjezeka kwa kuchuluka ndi mtengo wa unit, motero kukweza mtengo wazithunzi za LED.
2.2 Pixel Pitch
Izi zimatengera mtunda wanu wowonera.
RTLED imapereka zithunzi za P1.86mm mpaka P3.33mm za LED. Ndipo kucheperako kwa ma pixel, kumakwera mtengo.
2.3 Kupaka
RTLEDimapereka njira ziwiri: mabokosi amatabwa ndi zonyamula ndege, iliyonse ili ndi mawonekedwe ake komanso mtengo wake.
Kupaka kwa crate yamatabwa kumagwiritsa ntchito zida zamatabwa zolimba, zomwe zimapereka kukonza kokhazikika komanso kodalirika kwazinthu, kukana kugundana, kugwedezeka, ndi mphamvu zina zakunja panthawi yodutsa, ndi ndalama zotsika mtengo, zoyenera kwa makasitomala omwe ali ndi zofunikira zina zotetezedwa ndikuyang'ana pa mtengo- mphamvu.
Kupaka kwa ndege kumapereka chitetezo chokwanira komanso mwayi wowoneka bwino, wokhala ndi zida zabwino kwambiri komanso zaluso zapamwamba, kapangidwe kake ka mkati, kupatsa zikwangwani za LED chisamaliro chokwanira, makamaka oyenera mawonekedwe apamwamba ogwiritsira ntchito okhala ndi chitetezo chokhazikika chazinthu komanso zofunikira pamayendedwe, pa mtengo wokwera kwambiri, kuchepetsa nkhawa zanu mukamayenda ndi kusungirako.
3. mapeto
Mwachidule, mtengo wazithunzi za digito za LED zimasiyana malinga ndi kasinthidwe ndi zigawo zake. Mtengo nthawi zambiri umachokera$1,000 mpaka $2,500. Ngati mukufuna kuyitanitsa chophimba chazithunzi za LED,ingotisiyirani uthenga.
