Ukuze uqale, kubalulekile ukubamba okuyisisekelo kwama-LED we-Surface-Mounted Device (SMD). Ngokungangabazeki ama-LED asetshenziswa kakhulu njengamanje. Ngenxa yokuguquguquka kwayo, ngisho nakukukhanya kwesaziso se-smartphone, i-chip ye-LED ihlanganiswe ngokuqinile ebhodini lesifunda eliphrintiwe futhi isetshenziswa kabanzi. Esinye sezici ezihluke kakhulu zama-chips e-SMD LED inombolo yokuxhumana nama-diode.
Kuma-chips e-SMD LED, kungenzeka ukuthi ube nokuxhumana okungaphezu kokubili. Ama-diode afinyelela kwamathathu anamasekhethi angawodwana angatholakala ku-chip eyodwa. Isifunda ngasinye singaba ne-anode ne-cathode, okuholela ekuxhumekeni okungu-2, 4, noma okungu-6 ku-chip.
Umehluko phakathi kwama-COB LED nama-SMD LEDs.
Ku-chip eyodwa ye-SMD LED, kungaba nama-diode afika kwamathathu, ngalinye linomjikelezo walo. Isifunda ngasinye ku-chip yalolu hlobo sine-cathode eyodwa ne-anode eyodwa, okuholela ekuxhumekeni okungu-2, 4, noma okungu-6. Ama-COB chips ngokuvamile anama-diode ayisishiyagalolunye noma ngaphezulu. Ngaphezu kwalokho, ama-COB chips anokuxhumana okubili kanye nesekethe eyodwa kungakhathaliseki inani lama-diode. Ngenxa yalo mklamo olula wesekethe, izibani ze-COB LED zinokubukeka okufana nephaneli, kanti izibani ze-SMD LED zingabonakala ziyiqoqo lezibani ezincane.
I-diode ebomvu, eluhlaza, neluhlaza okwesibhakabhaka ingaba khona ku-chip ye-SMD LED. Ngokushintsha izinga lokuphumayo lama-diode amathathu, ungakhiqiza noma iyiphi i-hue. Kumalambu we-COB LED, nokho, kukhona abathintwayo ababili kuphela kanye nesekhethi eyodwa. Akunakwenzeka ukuwasebenzisa ukwenza izibani ezishintsha umbala noma ama-bulb. Kudingeka ukulungiswa kweziteshi eziningi ukuze uthole umphumela oshintsha umbala. Ngenxa yalokho, izibani ze-COB LED zisebenza kahle ezinhlelweni ezidinga umbala owodwa kodwa hhayi imibala embalwa.
Ama-chips e-SMD anebanga lokukhanya elaziwayo lama-lumens angama-50 kuye kwayi-100 ngewathi ngayinye. Ukusebenza kahle okukhulu kokushisa kanye ne-lumens ngesilinganiso se-watt ngayinye ye-COB kwaziwa kahle. Ama-COB chips angakhipha ama-lumens amaningi ngogesi omncane uma okungenani enamalumens angama-80 ngewathi ngayinye. Ingatholakala ezinhlotsheni eziningi ezihlukene zamalambu namadivayisi, njengesibani esisefonini yakho noma amakhamera akhombe bese udubula.
Kudingeka umthombo wamandla wangaphandle omncane kuma-chips e-SMD LED, kuyilapho umthombo wamandla wangaphandle omkhulu udingeka kuma-COB LED chips.
