Zowonetsera za LED zasintha momwe timaperekera chidziwitso, mkati ndi kunja. Mitundu iwiri yodziwika bwino yaukadaulo wa LED imayang'anira msika: SMD (Surface-Mounted Device) LED ndi DIP (Dual In-line Package) LED. Aliyense ali ndi mawonekedwe apadera, ndipo kudziwa kusiyana kwawo ndikofunikira kuti mupange chisankho choyenera malinga ndi momwe mungagwiritsire ntchito. Tiyeni tidutse mitundu iwiri iyi ya zowonetsera za LED ndikuwona momwe zimasiyanirana ndi mawonekedwe, magwiridwe antchito, ndi kagwiritsidwe ntchito.
1. Kapangidwe ka LED
Kusiyana kwakukulu pakati pa ma SMD ndi ma LED a DIP kuli pamawonekedwe awo:
Chiwonetsero cha LED cha SMD: Pachiwonetsero cha SMD, tchipisi ta LED timayikidwa pamwamba pa bolodi losindikizidwa (PCB). LED imodzi ya SMD imakhala ndi ma diode ofiira, obiriwira, ndi abuluu mu phukusi limodzi, kupanga pixel.
DIP LED Display: Ma LED a DIP amakhala ndi ma diode ofiira, obiriwira, ndi abuluu omwe amaikidwa mu chipolopolo cholimba cha utomoni. Ma LED awa amayikidwa m'mabowo mu PCB, ndipo diode iliyonse imakhala gawo la pixel yayikulu.
2. Mapangidwe a Pixel ndi Kachulukidwe
Kapangidwe ka ma LED kumakhudza kachulukidwe ka pixel ndi kumveka bwino kwamitundu yonseyi:
SMD: Chifukwa ma diode onse atatu (RGB) ali mu phukusi laling'ono, ma SMD LED amalola kuchulukira kwa pixel. Izi zimawapangitsa kukhala abwino kwa mawonedwe apamwamba kwambiri pomwe zofunikira komanso zithunzi zakuthwa zimafunikira.
DIP: Diode yamtundu uliwonse imayikidwa padera, zomwe zimachepetsa kachulukidwe ka pixel, makamaka pamawonekedwe ang'onoang'ono. Zotsatira zake, ma LED a DIP amagwiritsidwa ntchito m'mapulogalamu omwe kuwongolera kwakukulu sikuli kofunikira kwambiri, monga zowonera zazikulu zakunja.
3. Kuwala
Kuwala ndi chinthu china chofunikira posankha pakati pa zowonetsera za SMD ndi DIP za LED:
SMD: Ma LED a SMD amapereka kuwala pang'ono, komwe kumakhala koyenera m'nyumba kapena kunja. Ubwino wawo waukulu ndikuphatikizana kwamtundu wapamwamba komanso mtundu wazithunzi, m'malo mowala kwambiri.
DIP: Ma LED a DIP amadziwika chifukwa chowala kwambiri, kuwapangitsa kukhala abwino kwa ntchito zakunja. Atha kukhala owoneka bwino pakuwunika kwadzuwa, womwe ndi umodzi mwamaubwino awo paukadaulo wa SMD.
4. Mbali Yowonera
Kuyang'ana kumatanthawuza momwe mungawonere zowonetsera kutali popanda kutaya mawonekedwe:
SMD: Ma LED a SMD amapereka ngodya yowonera mokulirapo, nthawi zambiri mpaka madigiri 160 mopingasa komanso molunjika. Izi zimawapangitsa kukhala chisankho chodziwika bwino pazowonetsera zamkati, momwe omvera amawonera zowonera kuchokera kumakona angapo.
DIP: Ma LED a DIP amakhala ndi ngodya yocheperako yowonera, nthawi zambiri pafupifupi madigiri 100 mpaka 110. Ngakhale izi ndizokwanira pazokonda zakunja komwe owonera amakhala kutali, sizoyenera kuwonera cham'mbali kapena mopanda mbali.
5. Kukhalitsa ndi Kukaniza Nyengo
Kukhalitsa ndikofunikira, makamaka pazowonetsa zakunja zomwe zimakumana ndi zovuta zanyengo:
SMD: Ngakhale ma LED a SMD ndi oyenera kugwiritsidwa ntchito panja zambiri, amakhala olimba kuposa ma DIP LED munyengo yoopsa. Mapangidwe awo okwera pamwamba amawapangitsa kukhala osatetezeka pang'ono kuwonongeka ndi chinyezi, kutentha, kapena kukhudzidwa.
DIP: Ma LED a DIP nthawi zambiri amakhala olimba ndipo amapereka kukana kwanyengo. Bokosi lawo loteteza utomoni limawathandiza kupirira mvula, fumbi, komanso kutentha kwambiri, zomwe zimawapangitsa kukhala osankha kukhazikitsa zazikulu zakunja monga zikwangwani.
6. Mphamvu Mwachangu
Kugwiritsa ntchito mphamvu kumatha kukhala kodetsa nkhawa pakukhazikitsa kwanthawi yayitali kapena kwakukulu:
SMD: Zowonetsera za SMD ndizopatsa mphamvu zambiri kuposa zowonetsera za DIP chifukwa cha mapangidwe ake apamwamba komanso kukula kwake. Amafuna mphamvu zochepa kuti apange mitundu yowoneka bwino komanso zithunzi zatsatanetsatane, zomwe zimawapangitsa kukhala chisankho chabwino pamapulojekiti okonda mphamvu.
DIP: Zowonetsera za DIP zimadya mphamvu zambiri kuti zikwaniritse zowala kwambiri. Kuchuluka kwa magetsi kumeneku kungapangitse kuti pakhale ndalama zambiri zogwirira ntchito, makamaka zoika panja zomwe zimayenda mosalekeza.
7. Mtengo
Bajeti imakhala ndi gawo lalikulu pakusankha pakati pa zowonetsera za SMD ndi DIP za LED:
SMD: Kawirikawiri, mawonedwe a SMD ndi okwera mtengo kwambiri chifukwa cha luso lawo lapamwamba komanso njira zopangira zovuta. Komabe, magwiridwe antchito awo potengera kulondola kwamtundu komanso kuchuluka kwa pixel kumatsimikizira mtengo wamapulogalamu ambiri.
DIP: Zowonetsera za DIP nthawi zambiri zimakhala zotsika mtengo, makamaka pazowonjezera zazikulu, zotsika kwambiri zakunja. Kutsika mtengo kumawapangitsa kukhala chisankho chodziwika bwino pama projekiti omwe amafunikira kulimba koma osati mwatsatanetsatane.
8. Common Application
Mtundu wa chiwonetsero cha LED chomwe mwasankha chidzadalira kwambiri zomwe mukufuna kugwiritsa ntchito:
SMD: Ma LED a SMD amagwiritsidwa ntchito kwambiri powonetsera m'nyumba, kuphatikiza zipinda zamisonkhano, zikwangwani zamalonda, ziwonetsero zamalonda, ndi ma studio apawayilesi. Amapezekanso m'makhazikitsidwe ang'onoang'ono akunja komwe kuli kofunikira kwambiri, monga zowonera zotsatsa zapafupi.
DIP: Ma LED a DIP amalamulira makhazikitsidwe akuluakulu akunja, monga zikwangwani, zowonetsera masitediyamu, ndi zowonera panja. Mapangidwe awo olimba komanso kuwala kwakukulu kumawapangitsa kukhala abwino kwambiri m'malo omwe kulimba kwambiri komanso mawonekedwe adzuwa amafunikira.
Kutsiliza: Kusankha Pakati pa SMD ndi DIP LED Zowonetsera
Mukasankha pakati pa chiwonetsero cha SMD ndi DIP LED, ndikofunikira kuganizira zofunikira za polojekiti yanu. Ngati mukufuna mawonekedwe apamwamba, ma angles owoneka bwino, komanso mawonekedwe abwinoko azithunzi, makamaka pazokonda zamkati, zowonetsera za SMD LED ndi njira yopitira. Kumbali inayi, pamakhazikitsidwe akuluakulu akunja komwe kuwala, kulimba, komanso kutsika mtengo ndikofunikira, zowonetsera za DIP LED nthawi zambiri zimakhala zabwinoko.
