Lapho uthenga izibani, ngokuvamile uzwa abasebenzi bezokuthengisa bethi siyizibani ze-LED, ukuvikelwa kwemvelo nokonga amandla, manje yonke indawo futhi singezwa ngamagama aholwa, ngaphezu kwezibani zethu eziholayo ezijwayelekile zokuvikela imvelo nokonga amandla, sivame ukuzwa abantu bekhuluma ngezibani zezikhwebu. , ngikholwa ukuthi abantu abaningi abanakho ukuqonda okujulile kwesikhwebu, manje-ke yini isikhwebu?Uyini umehluko nge-led?
Inkulumo yokuqala nge-LED, isibani esikhonjiwe siyi-diode ekhipha ukukhanya njengomthombo wokukhanya, isakhiwo saso esiyisisekelo i-electroluminescent semiconductor chip, iyisisetshenziswa esiqinile se-semiconductor, singaguqula ugesi ube ukukhanya.Umkhawulo owodwa we-chip unamathiselwe kubakaki, umkhawulo owodwa i-electrode engalungile, kanti enye ixhunywe ku-electrode enhle yokunikezwa kwamandla, ukuze yonke i-chip ihlanganiswe ne-epoxy resin, evikela intambo yangaphakathi yangaphakathi. , bese kufakwa igobolondo, ngakho ukusebenza kokuzamazama kwesibani se-LED kuhle.I-LED ekhanyayo I-Angle inkulu, ingafinyelela ama-degree angu-120-160, uma kuqhathaniswa nephakheji yangaphambili ye-plug-in ukusebenza kahle okuphezulu, ukunemba okuhle, izinga eliphansi lokushisela, isisindo esincane, ivolumu encane njalonjalo.
Ezinsukwini zakuqala, sasibona izindawo zokugunda izinwele, i-KTV, izindawo zokudlela, amathiyetha nezinye izibani eziholayo ezakhiwe izinombolo noma amagama ayesetshenziswa kakhulu kumabhodi ezikhangiso, futhi izibani ze-LED zazisetshenziswa kakhulu njengezinkomba kanye namabhodi e-LED.Ngokuvela kwama-leds amhlophe, nawo asetshenziswa njengokukhanyisa.
I-LED yaziwa njengomthombo wokukhanyisa wesizukulwane sesine noma umthombo wokukhanya oluhlaza okonga amandla, ukuvikelwa kwemvelo, impilo ende, usayizi omncane, izici eziphephile nezithembekile, ezisetshenziswa kabanzi ezinhlobonhlobo zezinkomba, isibonisi, umhlobiso, ukukhanya okungemuva, ukukhanya okujwayelekile kanye indawo yasemadolobheni ebusuku kanye nezinye izinkambu.Ngokusho kokusetshenziswa kwemisebenzi ehlukene, ingahlukaniswa ngokubonisa ulwazi, amalambu omgwaqo, amalambu emoto, i-backlight yesikrini se-LCD, ukukhanya okujwayelekile kwezigaba ezinhlanu.
Ngokombono, impilo yesevisi yezibani ze-LED (ama-diode akhipha ukukhanya okukodwa) ngokuvamile amahora angu-10,000.Kodwa-ke, ngemva kokuhlanganisa isibani, ngoba ezinye izingxenye ze-elekthronikhi nazo zinokuphila, ngakho-ke isibani se-LED asikwazi ukufinyelela amahora angu-10,000 wokuphila kwenkonzo, ngokuvamile, singafinyelela amahora angu-5,000 kuphela.
Umthombo wokukhanya we-COB usho ukuthi i-chip ihlanganiswe ngokuqondile kuyo yonke i-substrate, okungukuthi, ama-N chips azuzwa njengefa futhi ahlanganiswe ndawonye ku-substrate ukuze afakwe.Lobu buchwepheshe buqeda umqondo wokusekela, akukho plating, akukho ukugeleza kabusha, akukho nqubo ye-patch, ngakho-ke inqubo yehliswa cishe nge-1/3, futhi izindleko nazo zigcinwa ngo-1/3.Isetshenziselwa kakhulu ukuxazulula inkinga yokukhiqiza izibani ze-LED zamandla aphansi we-chip, ezingahlakaza ukuchithwa kokushisa kwe-chip, kuthuthukise ukusebenza kahle kokukhanya, futhi kuthuthukise umphumela we-glare wezibani ze-LED.I-COB inobuningi obukhanyayo obukhanyayo, i-glare encane nokukhanya okuthambile, futhi ikhipha ukukhanya okufanayo kokusabalalisa.Ngamagama adumile, ithuthuke kakhulu kunezibani eziholayo, izibani eziningi zokuvikela amehlo.
Umehluko phakathi kwelambu le-Cob nesibani esiholayo ukuthi isibani esiholayo singasindisa ukuvikelwa kwemvelo, akukho stroboscopic, akukho misebe ye-ultraviolet, futhi okubi kuwukulimala kokukhanya okuluhlaza okwesibhakabhaka.Ukunikezwa kombala wesibani esiphezulu, umbala okhanyayo eduze nombala wemvelo, akukho stroboscopic, akukho ukukhanya, akukho misebe kagesi, akukho misebe ye-ultraviolet, imisebe ye-infrared ingavikela amehlo nesikhumba.Lezi ezimbili empeleni ziyi-LED, kodwa indlela yokupakisha ihlukile, inqubo yokupakisha i-cob kanye nokusebenza kahle kokukhanya kunenzuzo enkulu, kuwumkhuba wokuthuthukiswa kwesikhathi esizayo.
