Ukuqala, kuyafuneka ukuba ube nokuqonda okusisiseko kwee-LED ze-SMD. Ngokungathandabuzekiyo zii-LEDs ezisetyenziswa rhoqo ngoku. Ngenxa yokuguquguquka kwayo, nakwisibane sesaziso se-smartphone, i-chip ye-LED idityaniswe ngokuqinileyo kwibhodi yesekethe eprintiweyo kwaye iqeshwe ngokubanzi. Enye yezona mpawu zibalaseleyo ze-SMD ze-chips ze-LED linani loqhagamshelo kunye ne-diode.
Kwiitshiphusi ze-SMD ze-LED, kunokwenzeka ukuba ube nonxibelelwano olungaphezulu kwesibini. Ukuya kuthi ga kwiidiode ezintathu ezineesekethe zomntu ngamnye zinokufumaneka kwi-chip enye. Isiphaluka ngasinye siya kuba ne-anode kunye ne-cathode, okukhokelela kunxibelelwano lwe-2, 4, okanye i-6 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 yolu hlobo inecathode enye kunye ne-anode enye, okukhokelela kunxibelelwano olu-2, lwesi-4, okanye olu-6. Iichips zeCOB zihlala zine-diode ezisithoba okanye ngaphezulu. Ngaphaya koko, iitshiphusi ze-COB zineqhagamshelo ezimbini kunye nesekethe enye kungakhathaliseki ubungakanani beediode. Ngenxa yolu yilo olulula lwesekethe, izibane zeCOB ze-LED zinenkangeleko efana nephaneli, ngelixa izibane ze-SMD ze-LED zinokubonakala ziyingqokelela yezibane ezincinci.
Idiode ebomvu, eluhlaza, nebhlowu inokubakho kwi-chip ye-SMD LED. Ngokutshintsha inqanaba lemveliso yeediode ezintathu, unokuvelisa nayiphi na i-hue. Kwizibane ze-COB ze-LED, nangona kunjalo, kukho abafowunelwa ababini kuphela kunye nesekethe enye. Akunakwenzeka ukuzisebenzisa ukwenza izibane ezitshintsha umbala okanye iibhalbhu. Ulungelelwaniso lwetshaneli ezininzi luyafuneka ukufumana umphumo wokutshintsha umbala. Ngenxa yoko, izibane ze-COB ze-LED zisebenza kakuhle kwizicelo ezifuna i-hue enye kodwa ingabi nemibala emininzi.
Iitshiphusi ze-SMD zinoluhlu olukhanyayo olwaziwayo lwe-50 ukuya kwi-100 lumens ngewatt nganye. Ukusebenza kakuhle kobushushu kunye ne-lumens ngokwe-watt ratio ye-COB yaziwa kakuhle. Iitshiphusi zeCOB zinokukhupha iilumens ezininzi ezinombane omncinci ukuba zineelumens ezingama-80 ubuncinane ngewathi nganye. Inokufumaneka kwiindidi ezininzi ezahlukeneyo zeebhalbhu kunye nezixhobo, ezinje ngokukhanya kwifowuni yakho okanye ukukhomba-kwaye-ukudubula iikhamera.
Umthombo wamandla wangaphandle omncinci uyafuneka kwiitshiphusi ze-SMD ze-LED, ngelixa umthombo wamandla wangaphandle omkhulu ufuneka kwi-COB LED chips.
