Okokuqala, kuyimfuneko ukuba nolwazi olusisiseko ngee-LED ze-surface mount device (SMD). Ngokungathandabuzekiyo zezona LED zisetyenziswa rhoqo okwangoku. Ngenxa yokuguquguquka kwazo, ii-chips ze-LED zihlanganiswe ngokuqinileyo kwiibhodi zesekethe eziprintiweyo kwaye zisetyenziswa kakhulu nakwii-smartphones zesaziso. Enye yezona zinto zibalulekileyo kwii-chips ze-SMD LED linani lonxibelelwano kunye nee-diode.
Kwitshiphu ye-SMD LED, kunokubakho uqhagamshelo olungaphezulu kwesibini. Kunokufumaneka ii-diode ezintathu ezineesekethe ezizimeleyo kwitshiphu enye. Isekethe nganye ine-anode kunye ne-cathode, nto leyo ebangela uqhagamshelo olu-2, olu-4, okanye olu-6 kwitshiphu.
Umahluko phakathi kwee-COB LEDs kunye nee-SMD LEDs
Kwitshiphu enye ye-SMD LED, kunokubakho ii-diode ezifikelela kwisithathu, nganye inesekethe yayo. Isekethe nganye kwitshiphu enjalo ine-cathode kunye ne-anode, nto leyo ebangela uqhagamshelo olu-2, olu-4, okanye olu-6. Iitshiphu ze-COB zihlala zinee-diode ezilithoba nangaphezulu. Ukongeza, iitshiphu ze-COB zinee-connections ezimbini kunye nesekethe enye nokuba inani lee-diode lingakanani na. Ngenxa yolu yilo lwesekethe lulula, izibane ze-COB LED zibonakala ngathi zifana nepaneli, ngelixa izibane ze-SMD LED zibonakala ngathi liqela lezibane ezincinci.
Iidayidi ezibomvu, eziluhlaza, neziluhlaza okwesibhakabhaka zinokubakho kwitshiphu ye-SMD LED. Ngokutshintsha amanqanaba okukhupha iidayidi ezintathu, ungavelisa naluphi na umbala. Nangona kunjalo, kwisibane se-COB LED kukho oonxibelelwano ababini kuphela kunye nesekethe. Akunakwenzeka ukwenza isibane okanye ibhalbhu etshintsha umbala ngazo. Uhlengahlengiso lweendlela ezininzi luyadingeka ukuze ufumane isiphumo sokutshintsha umbala. Ke ngoko, izibane ze-COB LED zisebenza kakuhle kwizicelo ezifuna umbala omnye endaweni yemibala emininzi.
Uluhlu lokukhanya kweetships ze-SMD lwaziwa kakhulu ngokuba zii-lumens ezingama-50 ukuya kwi-100 nge-watt nganye. I-COB yaziwa kakhulu ngokusebenza kwayo okuphezulu kobushushu kunye nomlinganiselo we-lumen nge-watt nganye. Ukuba itships ye-COB ine-lumens ezingama-80 ubuncinane nge-watt nganye, inokukhupha ii-lumens ezininzi ngombane omncinci. Ingasetyenziswa kwiintlobo ezahlukeneyo zeebhalbhu kunye nezixhobo, ezifana ne-flash yefowuni ephathwayo okanye iikhamera ze-point-and-shoot.
Ukongeza koku, iitships ze-SMD LED zifuna umthombo wamandla omncinci wangaphandle, ngelixa iitships ze-COB LED zifuna umthombo wamandla omkhulu wangaphandle.
