Okokuqala, kuyimfuneko ukuba ube nokuqonda okusisiseko kwesixhobo sokunyuswa komhlaba (SMD) LEDs. Ngokungathandabuzekiyo zezona LED zisetyenziswa rhoqo ngoku. Ngenxa yokuguquguquka kwazo, iitshiphusi ze-LED zidityaniswe ngokuqinileyo kwiibhodi zesekethe eziprintiweyo kwaye zisetyenziswa ngokubanzi nakwizibane zesaziso se-smartphone. Enye yezona zinto ziphawuleka kakhulu kwiitshiphusi ze-SMD ze-LED linani lonxibelelwano kunye neediode.
Kwi-chip ye-SMD ye-LED, kunokubakho ukudibanisa okungaphezulu kweebini. Ukuya kuthi ga kwiidiode ezintathu ezinezijikelezo ezizimeleyo zingafumaneka kwi-chip enye. Isekethe nganye ine-anode kunye ne-cathode, ekhokelela kwi-2, 4, okanye i-6 ukudibanisa kwi-chip.
Umahluko phakathi kwee-COB ze-LED kunye nee-SMD ze-LED
Kwi-chip eyodwa ye-SMD ye-LED, kunokubakho ukuya kuthi ga kwiidiode ezintathu, nganye inesekethe yayo. Isekethe nganye kwi-chip enjalo ine-cathode kunye ne-anode, okubangelwa ukudibanisa kwe-2, 4, okanye i-6. Iitshiphusi ze-COB zihlala zine-diode ezilithoba nangaphezulu. Ukongeza, ii-chips ze-COB zineziqhagamshelo ezimbini kunye nesekethe enye kungakhathaliseki ukuba inani le-diode. Ngenxa yolu yilo olulula lwesekethe, izibane ze-COB ze-LED zinembonakalo efana nephaneli, ngelixa izibane ze-SMD ze-LED zibukeka njengeqela lezibane ezincinci.
Iidiode ezibomvu, eziluhlaza, eziluhlaza okwesibhakabhaka zinokubakho kwi-chip ye-SMD LED. Ngokutshintsha amanqanaba okuphuma kweediode ezintathu, unokuvelisa nayiphi na i-hue. Kwisibane se-COB se-LED, nangona kunjalo, kukho abafowunelwa ababini kuphela kunye nesekethe. Akunakwenzeka ukwenza isibane esitshintsha umbala okanye ibhalbhu kunye nabo. Ukulungelelaniswa kweetshaneli ezininzi kuyafuneka ukufumana umphumo wokutshintsha umbala. Ke ngoko, izibane ze-COB ze-LED zisebenza kakuhle kwizicelo ezifuna i-hue enye kunemibala emininzi.
Uluhlu lokukhanya kweetshiphusi ze-SMD luyaziwa kakuhle ukuba luyi-50 ukuya kwi-100 lumens ngewatt nganye. I-COB yaziwa ngokusebenza kwayo okuphezulu kwe-thermal kunye ne-lumen ngokwe-watt ratio. Ukuba i-chip ye-COB ine-lumens engama-80 ubuncinane ngewathi nganye, inokukhupha i-lumens eninzi ngombane omncinci. Ingasetyenziswa kwiindidi ezininzi ezahlukeneyo zeebhalbhu kunye nezixhobo, ezifana neflash yefowuni ephathwayo okanye iikhamera zokukhomba kunye nokudubula.
Ukongeza koku, ii-chips ze-SMD ze-LED zifuna umthombo omncinci wamandla wangaphandle, ngelixa ii-chips ze-COB ze-LED zifuna umthombo wamandla wangaphandle omkhulu.
