Okokuqala, kubalulekile ukuba nokuqonda okuyisisekelo ngama-LED edivayisi yokubeka phezulu (i-SMD). Akungabazeki ukuthi angama-LED asetshenziswa kakhulu njengamanje. Ngenxa yokuguquguquka kwawo, ama-chip e-LED ahlanganiswe ngokuqinile namabhodi wesekethe aphrintiwe futhi asetshenziswa kabanzi ngisho nasezibanini zesaziso ze-smartphone. Esinye sezici eziphawuleka kakhulu zama-chip e-SMD LED inani lokuxhumana nama-diode.
Ku-chip ye-SMD LED, kungaba nokuxhumana okungaphezu kokubili. Kungatholakala ama-diode amathathu anezisekethe ezizimele ku-chip eyodwa. Isekethe ngayinye ine-anode kanye ne-cathode, okuholela ekuxhumekeni okungu-2, 4, noma 6 ku-chip.
Umehluko phakathi kwama-LED e-COB nama-LED e-SMD
Ku-chip eyodwa ye-SMD LED, kungaba nama-diode afinyelela kwantathu, ngalinye linesekethe yalo. Isekethe ngayinye ku-chip enjalo ine-cathode kanye ne-anode, okuholela ekuxhumekeni okungu-2, 4, noma okungu-6. Ama-chip e-COB avame ukuba nama-diode ayisishiyagalolunye noma ngaphezulu. Ngaphezu kwalokho, ama-chip e-COB anokuxhumana okubili kanye nesekethe elilodwa kungakhathaliseki inani lama-diode. Ngenxa yalolu hlobo lomklamo olula wesekethe, izibani ze-COB LED zibukeka njengephaneli, kuyilapho izibani ze-SMD LED zibukeka njengeqembu lezibani ezincane.
Ama-diode abomvu, aluhlaza okotshani, naluhlaza okwesibhakabhaka angaba khona ku-chip ye-SMD LED. Ngokushintsha amazinga okukhipha ama-diode amathathu, ungakhiqiza noma yimuphi umbala. Nokho, esibanini se-COB LED, kunezixhumi ezimbili kuphela kanye nesekethe. Akunakwenzeka ukwenza isibani noma i-bulb eshintsha umbala ngazo. Kudingeka ukulungiswa kweziteshi eziningi ukuze uthole umphumela wokushintsha umbala. Ngakho-ke, izibani ze-COB LED zisebenza kahle ezinhlelweni ezidinga umbala owodwa kunemibala eminingi.
Ububanzi bokukhanya kwama-chip e-SMD baziwa kakhulu ngokuthi ama-lumens angu-50 kuya kwangu-100 nge-watt ngayinye. I-COB yaziwa kakhulu ngokusebenza kwayo kahle kokushisa okuphezulu kanye nesilinganiso se-lumen nge-watt ngayinye. Uma i-chip ye-COB inama-lumens okungenani angu-80 nge-watt ngayinye, ingakhipha ama-lumens amaningi ngogesi omncane. Ingasetshenziswa ezinhlotsheni eziningi ezahlukene zama-bulb namadivayisi, njenge-flash yefoni ephathekayo noma amakhamera okukhomba nokudubula.
Ngaphezu kwalokhu, ama-chip e-SMD LED adinga umthombo wamandla wangaphandle omncane, kuyilapho ama-chip e-COB LED edinga umthombo wamandla wangaphandle omkhulu.
