Uyini umehluko phakathi kwemichilo yokukhanya kwe-cob kanye nemichilo yokukhanya ye-LED evamile?

Umehluko phakathi kwama-cob light strips kanye nama-led strips

Yiziphi izibani ze-LED nezibani ze-COB

Isibani se-LED, igama eligcwele liyisibani se-diode esikhanyayo, siwumthombo wokukhanya we-semiconductor. Yakhiwe ngokuhlangana kwe-PN. Lapho ama-electron nezimbobo kuhlangana kabusha ekuhlanganeni kwe-PN, kuphuma ukukhanya. Izibani ze-LED zinezinzuzo zokusebenza kahle okuphezulu, impilo ende, umbala okhanyayo ogcwele, ukonga amandla nokuvikelwa kwemvelo, njll., ngakho-ke asetshenziswa kakhulu ekukhanyiseni, ekuboniseni, ekuboniseni, ekuboniseni nakwezinye izinkambu.

Isibani se-COB, esimele ubuhlalu belambu obupakishwe yi-chip, siwuhlobo olusha lomthombo wokukhanyisa. Ipakisha ama-chips amaningi e-LED ku-substrate efanayo ukuze kwakhe umthombo wokukhanya we-semiconductor ukuze umiselele ubuhlalu besibani be-LED bendabuko, ngaleyo ndlela kuzuzwe ukusebenza kahle kokukhanya nokukhanya okuphezulu. Izibani ze-COB zinezinzuzo zokusebenza kahle kokukhanya, umbala wokukhanya okufanayo, nokukhanya okuphezulu, ngakho-ke asetshenziswa kakhulu ekukhanyisweni kokuhweba, ukukhanyisa kwangaphakathi nezinye izinkambu.

1. Isakhiwo somthombo wokukhanya

I-COB (Chip on Board) isibani esikhanyayo isibani esihlanganisa ama-chips amaningi e-LED ku-substrate. Ama-chips e-LED amaningi ku-substrate ahlelwa eceleni ukuze akhe wonke, futhi indawo ekhipha ukukhanya iyaqhubeka futhi iyafana. Umucu wokukhanya we-LED (Light Emitting Diode) uhlela ama-chips e-LED eyodwa eceleni komugqa wokukhanya. Ngakho-ke, isakhiwo somthombo wokukhanya wamapheshana okukhanya we-COB sihlangene kakhulu futhi sihlanganisiwe, kuyilapho umthombo wokukhanya wamapheshana okukhanya we-LED uhlakazeke kakhulu.

2. Ukukhanya

Ngenxa yokuthi isakhiwo somthombo wokukhanya semicu yokukhanya ye-COB sihlangene kakhulu, lapho ama-chips e-LED amaningi esebenza ngesikhathi esisodwa, indawo ekhipha ukukhanya inkulu futhi ukukhanya kuphakeme. Njengoba umthombo wokukhanya wemigqa yokukhanya ye-LED uhlakazekile futhi ama-chips e-LED ngamanye mancane, ukukhanya kwawo kuphansi. Ngakho-ke, lapho imiphumela yokukhanya ephezulu idingeka, kufanelekile kakhulu ukukhetha imichilo yokukhanya ye-COB.

3. Ukusebenza kahle kwamandla

Umphumela wokukhanyisa we-COB light strips ungcono uma kuqhathaniswa, ukukhanya kufana, umphumela wokubonisa unamandla, nokusebenza kahle kwamandla kuphezulu. Ngenxa yokubumbana kwesakhiwo sayo somthombo wokukhanya, imichilo yokukhanya ye-COB ingalawula kangcono isiqondiso sokukhanya futhi inciphise ukulahleka kwamandla phakathi nenqubo yokukhanyisa. Kodwa-ke, ukusebenza kahle kwamandla kwemigqa yokukhanya kwe-LED kuncane kakhulu ngenxa yemithombo yokukhanya ehlakazekile phakathi nenqubo yokukhanyisa.Ngakho-ke, ngenkathi uphishekela ukusebenza kahle kwamandla, ukukhetha imichilo yokukhanya ye-COB kungasindisa amandla futhi kunciphise izindleko zokukhanyisa.

4. Inani

Ngenxa yokuthi imichilo yokukhanya ye-COB idinga izinqubo zokukhiqiza eziphezulu futhi ibe nemiphumela engcono yokukhanyisa nokusebenza kahle kwamandla, amanani ayo aphezulu uma kuqhathaniswa. Intengo yemichilo yokukhanya ye-LED iphansi kakhulu ngenxa yenqubo yabo elula yokukhiqiza. Ngakho-ke, uma isabelomali sinomkhawulo, kungase kube ukonga kakhulu ukukhetha imichilo yokukhanya ye-LED.

Izimo ezinhlanu zokusetshenziswa kwezibani ze-COB nezibani ze-LED

Izibani ze-COB nezibani ze-LED zinezinzuzo ezihlukene ezimeni ezihlukene zohlelo lokusebenza. Okulandelayo ukuhlaziya okuvela ezicini ezimbili: ukukhanya kwezentengiso nokukhanyisa kwangaphakathi:

ukukhanyisa kwezohwebo

Izigcawu zokukhanyisa ezentengiso zidinga izidingo eziphakeme zombala, ngakho-ke kunconywa ukukhetha amalambu e-COB. Ngenxa yokuthi izibani ze-COB zipakisha ama-chips e-LED amaningi endaweni engaphansi efanayo, umbala okhanyayo ufana kakhulu futhi ungaveza imibala engokoqobo. Ngasikhathi sinye, ukusebenza kahle kokukhanya kwezibani ze-COB nakho kuphezulu futhi kungafinyelela imiphumela engcono yokukhanyisa.

Ukukhanyisa kwangaphakathi

Izigcawu zokukhanyisa zasendlini zidinga amahora amaningi okusebenza, ngakho-ke kunconywa ukuthi ukhethe izibani ze-LED. Nakuba ukusebenza kahle okukhanyayo kwezibani ze-LED kungaphansi kwalokho kwezibani ze-COB, uma kuqhathaniswa namalambu okukhanya endabuko namalambu e-fluorescent, ukusebenza kahle okukhanyayo kwezibani ze-LED kusephezulu. Ngesikhathi esifanayo, impilo yezibani ze-LED nayo yinde, engahlangabezana nezidingo zokukhanyisa kwangaphakathi isikhathi eside.

Iziphakamiso zokukhetha izibani ze-COB nezibani ze-LED

Ngokuya ngesimo sohlelo lokusebenza, ukukhetha phakathi kwezibani ze-COB noma izibani ze-LED kufanele kuhluke. Okulandelayo iziphakamiso zokukhetha ezimweni ezehlukene:

1. Indawo yokukhanyisa ezohwebo: Kunconywa ukukhetha amalambu e-COB, angahlangabezana nesidingo sezidingo zombala eziphakeme.
2. Izimo zokukhanyisa zasendlini: Kunconywa ukukhetha izibani ze-LED, ezingahlangabezana nezidingo zokukhanyisa isikhathi eside.
3. Ezinye izimo: Khetha izibani ze-COB noma izibani ze-LED ngokwezidingo zangempela.

Ukufingqa, kunomehluko osobala phakathi kwemichilo yokukhanya ye-COB nemichilo yokukhanya ye-LED ngokwesakhiwo somthombo wokukhanya, ukukhanya, ukusebenza kahle kwamandla kanye nentengo. Imichilo yokukhanya ye-COB inezinzuzo zesakhiwo somthombo wokukhanya ohlangene, ukukhanya okuphezulu nokusebenza kahle kwamandla aphezulu, futhi ifanele izikhathi ezidinga imiphumela yokukhanya ephezulu nokonga amandla. Imichilo yokukhanya kwe-LED inenzuzo yamanani aphansi, futhi ingahlangabezana nezidingo ezithile zokukhanyisa ngaphansi kwezidingo ezithile zokukhanyisa. Ngakho-ke, lapho ukhetha imichilo yokukhanya, kufanele ucabangele ngokucophelela ngokusekelwe ezidingweni ezithile kanye nesabelomali ukuze wenze ukukhetha okunengqondo kakhulu.
