Okokuqala, kuyadingeka ukuba nokuqonda okuyisisekelo kwe-surface Mount device (SMD) LEDs. Ngokungangabazeki ama-LED asetshenziswa kakhulu njengamanje. Ngenxa yokuguquguquka kwawo, ama-chips e-LED ahlanganiswe ngokuqinile kumabhodi esekethe aphrintiwe futhi asetshenziswa kabanzi ngisho nasezibani zezaziso ze-smartphone. Esinye sezici eziphawuleka kakhulu zama-chips e-SMD LED inombolo yokuxhumana nama-diode.
Ku-chip ye-SMD LED, kungaba nokuxhumana okungaphezu kokubili. Kufika kuma-diode amathathu anamasekhethi azimele angatholakala ku-chip eyodwa. Isifunda ngasinye sine-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 enjalo sine-cathode ne-anode, 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, kuyilapho izibani ze-SMD LED zibukeka njengeqembu lezibani ezincane.
Ama-diode abomvu, aluhlaza, naluhlaza okwesibhakabhaka angaba khona ku-chip ye-SMD LED. Ngokushintsha amazinga okukhiphayo ama-diode amathathu, ungakhiqiza noma iyiphi i-hue. Kulambu le-COB LED, nokho, kukhona othintana nabo ababili kuphela kanye nesekethe. Akunakwenzeka ukwenza isibani esishintsha umbala noma isibani ngabo. Ukulungiswa kwamashaneli amaningi kuyadingeka ukuze uthole umphumela oshintsha umbala. Ngakho-ke, izibani ze-COB ze-LED zisebenza kahle ezinhlelweni ezidinga i-hue eyodwa kunemibala eminingi.
Ububanzi bokukhanya bama-chips e-SMD baziwa kahle ukuthi bungama-lumens angama-50 kuye kwayi-100 nge-watt ngayinye. I-COB yaziwa kakhulu ngokusebenza kwayo okushisayo okuphezulu kanye nesilinganiso se-lumen nge-watt ngayinye. Uma i-chip ye-COB inamalumens okungenani angu-80 ngewathi ngayinye, ingakhipha ama-lumens amaningi ngogesi omncane. Ingasetshenziswa ezinhlotsheni eziningi ezahlukene zamalambu namadivayisi, afana ne-flash yefoni ephathwayo noma amakhamera wokukhomba bese udubula.
Ngaphezu kwalokhu, ama-chips e-SMD LED adinga umthombo wamandla wangaphandle omncane, kuyilapho ama-COB LED chips adinga umthombo wamandla wangaphandle omkhulu.
