Tekinoloje ya LED yasintha dziko lonse la zowunikira ndi zowonetsera, zomwe zimapereka njira zogwiritsa ntchito mphamvu komanso zosunthika. Mitundu iwiri yodziwika bwino yaukadaulo wa LED ndi ma SMD (Surface-Mounted Device) ma LED ndi ma COB (Chip-on-Board) ma LED. Ngakhale kuti onsewa ali ndi ubwino wawo ndi ntchito zawo, kumvetsetsa kusiyana pakati pawo kungakuthandizeni kusankha teknoloji yoyenera ya LED pazosowa zanu.
Kodi SMD LED ndi chiyani?
Ma LED a Surface-Mounted Device (SMD) amayikidwa mwachindunji pamwamba pa bolodi yozungulira. Amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana, kuyambira zowonetsera za LED mpaka kuyatsa wamba. Ma LED a SMD amadziwika chifukwa cha luso lawo, kusinthasintha, komanso kuyika mosavuta.
Makhalidwe Ofunikira a ma SMD LEDs:
Kusinthasintha: Ma LED a SMD amabwera mosiyanasiyana ndi masinthidwe, kuwapangitsa kukhala oyenera kugwiritsa ntchito mitundu yosiyanasiyana, kuphatikiza mawonetsero, kuyatsa, ndi zizindikiro.
Kuwala: Amapereka milingo yowala kwambiri, kuwapangitsa kukhala abwino kwa mapulogalamu omwe mawonekedwe ndi ofunikira.
Zosankha Zamitundu: Ma LED a SMD amatha kupanga mitundu ingapo mwa kuphatikiza ma LED ofiira, obiriwira, ndi abuluu paphukusi limodzi.
Kuwotcha Kutentha: Ma LED a SMD ali ndi zinthu zabwino zowononga kutentha chifukwa cha mapangidwe awo, zomwe zimathandiza kusunga ntchito ndi moyo wautali.
Kodi COB LED ndi chiyani?
Ma LED a Chip-on-Board (COB) amaphatikiza kuyika tchipisi tambiri ta LED molunjika pagawo kuti apange gawo limodzi. Njirayi imapangitsa kuti kuwala kukhale kokwanira komanso kokwanira. Ma LED a COB amagwiritsidwa ntchito kwambiri pamawonekedwe apamwamba a lumen monga zowunikira, zowunikira, ndi kuyatsa kwapamwamba.
Makhalidwe Ofunika a COB LEDs:
Kutulutsa Kwapamwamba kwa Lumen: Ma COB LED amapereka kuwala kwapamwamba pa inchi imodzi poyerekeza ndi ma SMD LEDs, kuwapanga kukhala abwino kwa ntchito zowunikira kwambiri.
Kuwala Kofanana: Mapangidwe a COB LEDs amachititsa kuwala kofananirako komwe kumakhala ndi malo otentha ochepa, kumapanga chidziwitso chowunikira bwino.
Mapangidwe A Compact: Ma COB LED ndi ophatikizika ndipo amatha kulowa m'mapangidwe ang'onoang'ono, kupangitsa kuti pakhale mawonekedwe owunikira.
Kugwiritsa Ntchito Mphamvu Mwachangu: Ma COB LED ndi opatsa mphamvu kwambiri, amapereka kuwala kochulukirapo pomwe akugwiritsa ntchito mphamvu zochepa.
Kuyerekeza ma SMD ndi COB LEDs
Kutulutsa Kowala:
Ma LED a SMD: Perekani kuwala kowala koyenera kugwiritsa ntchito zosiyanasiyana, koma kumatha kutulutsa kuwala kobalalika.
Ma LED a COB: Perekani kuwala kowonjezereka komanso kofanana, koyenera kuyatsa kwambiri.
Kuwongolera Kutentha:
Ma LED a SMD: Nthawi zambiri amakhala ndi kutentha kwabwino chifukwa cha kupatukana kwa ma LED.
Ma LED a COB: Amafuna njira zowongolera kutentha chifukwa cha kuchuluka kwa ma LED m'dera laling'ono.
Mapulogalamu:
Ma LED a SMD: Osunthika komanso amagwiritsidwa ntchito kwambiri powonetsa, kuyatsa kwapakhomo, zikwangwani, ndi kuyatsa kwamagalimoto.
Ma LED a COB: Oyenera kwambiri pamapulogalamu omwe amafunikira kutulutsa kowala kwambiri ndi kuwala kofananako, monga kuyatsa kwa mafakitale, magetsi a mumsewu, ndi magetsi akumtunda.
Kusinthasintha Kwapangidwe:
Ma LED a SMD: Perekani kusinthasintha kwapangidwe chifukwa cha kupezeka kwawo mumitundu yosiyanasiyana ndi masanjidwe.
Ma LED a COB: Ophatikizana kwambiri koma angafunike zosintha zina kuti zigwirizane ndi mapangidwe awo.
Mapeto
Ma LED onse a SMD ndi COB ali ndi mphamvu zapadera ndipo ndi oyenerera ntchito zosiyanasiyana. Ngati mukufuna mayankho osinthika komanso osinthika okhala ndi mitundu ingapo yamitundu, ma SMD LED ndi njira yopitira. Kumbali ina, ngati mukufuna kuyatsa kwakukulu, kuyatsa kofananira ndi kapangidwe kakang'ono, ma COB LED ndiye chisankho chabwinoko. Kumvetsetsa kusiyana kumeneku kudzakuthandizani kupanga chisankho mwanzeru ndikuwongolera kuyatsa kwanu kapena njira zowonetsera kuti mugwire bwino ntchito komanso moyenera.
