Umehluko Womthombo Wokukhanya we-COB

Kungcono ukukhetha i-ballast ye-electronic ku-ballast, ngoba i-ballast ye-electronic inezici zokuthuthukisa umphumela wokukhanya nokuphila kwesibani. Njengamanje, yonke imithombo yokukhanya ye-fluorescent emakethe kufanele ibe ne-ballast ukuze ivutha. Kusukela ekuhlaziyweni kwenani lomsebenzi we-chip kanye nokuminyana okuhlanganisiwe kwe-chip, kutholakala ukuthi izinga lokushisa elihlanganisiwe le-multi-chip white light knot le-LED likhuphuka ngokwanda kwenani lama-chips ahlanganisiwe. Ukusebenza kahle kwayo okukhanyayo kwehlile ngokukhula kwenani lama-chips ahlanganisiwe, ngakho-ke inani lama-chips kanye nokuminyana okuhlanganisiwe nakho kuyisici esibalulekile esinomthelela ekusetshenzisweni kobuchwepheshe bokupakisha obuhlanganisiwe. Iphakethe le-Cob “Imodeli yomsuka wokukhanya we-COB →Amalambu we-LED ”, Ungakwazi ukufaka ngokuqondile ama-chips amaningi ku-MCPCB ebhodini lesifunda lokunyathelisa elisekelwe ensimbi, futhi ukhiphe ngokuqondile ukushisa nge-substrate ukuze wonge izindleko zokupakisha ze-LED, izindleko zokukhiqiza imojula yenjini ekhanyayo, nezindleko zokukhanyisa kwesibili. Ngokusebenza, ngokuklama okunengqondo kanye ne-microscope, imojula yomthombo wokukhanya we-COB ingagwema ngokuphumelelayo ukungalungi kokukhanya nokuxhopha okukhona ekuhlanganisweni kwamadivayisi omthombo wokukhanya wokuhlukanisa; kungase futhi kuthuthukise ngempumelelo umbala womthombo wokukhanya ngokwengeza inhlanganisela ye-chip ebomvu efanele ucansi. Indima yomthombo wokukhanya we-COB ukuletha i-voltage yokuqala esheshayo kanye ne-voltage ezinzile emthonjeni wokukhanya. Kungabonakala ukuthi ikhwalithi ye-ballast izonquma ngokuqondile umphumela wokuphila nokukhanya kwesibani. Ngaphezu kwevolumu, umthombo wokukhanya we-LED nawo unenzuzo yokuphila isikhathi eside. Lokhu futhi kuyinzuzo enkulu. Isivinini esisheshayo sesibani sinciphisa, kodwa isivinini sihamba kancane. Kusukela ezicini zokusebenzisa amalambu ahlukahlukene, imithombo yokukhanya ye-COB isetshenziselwa ikakhulukazi izinto zokukhanyisa zasendlini njengezibani ezikhanyayo ze-LED, izibani zophahla lwe-LED, njll. Isibalo esiphezulu se-watt esisodwa ngeke sidlule ku-50W. Imithombo yokukhanya ehlanganisiwe yamandla aphezulu isetshenziswa kakhulu ekukhanyisweni komgwaqo kanye nezibani zezimboni ezifana nezibani zasemgwaqweni zelanga, izibani zokukhanya ze-LED, izibani zomgwaqo ze-LED, izibani ze-LED zezimboni nezimayini. I-SMD ingena kancane esikhundleni semithombo yokukhanya ye-HP. Imithombo yokukhanya ye-HP okwamanje isetshenziswa ngaphandle. I-COB isenazo ezinye izindawo ezidinga ukuthuthukiswa. I-MCOB okwamanje ayinyuswanga esigabeni esikhona. Ukubambisana ukwethulwa kunezingxenye zamanje ze-COBoptical (i-aluminium noma i-PMMA materials village, njll.). Okwamanje, usayizi womthombo wokukhanya we-COB awukamiswa ngokugcwele. Uma imithombo yokukhanya ye-COB ingamahora angu-10,000, ukukhanya kungafinyelela ku-70% kuya ku-80% wokukhanya kwasekuqaleni, futhi umthombo wokukhanya wesibani ovamile ushintshiwe kabili kulesi sikhathi sokusetshenziswa. Phela, umthombo wokukhanya wendabuko ungasebenzisa kuphela amahora angu-4000 okukhanya. Ingxenye kuphela yokukhanya kokuqala ingaphansi kwengxenye yokukhethwa kwalo mthombo wokukhanya we-LED wamahhala. Umthombo wokukhanya we-COB ungaqondakala kalula njengomthombo wokukhanya ongaphezulu wamandla ahlanganisiwe. Indawo yokuphuma kanye nosayizi womumo womthombo wokukhanya ungaklanywa ngokuya ngesakhiwo somumo womkhiqizo. Njengemboni yamasu asafufusa ezweni lami, ukukhanya kwe-semiconductor. Kodwa-ke, emkhakheni wemithombo yokukhanya ye-LED ekhethekile, ngenxa yomkhawulo ophezulu wezobuchwepheshe, imakethe iye yaphathwa yizinkampani zangaphandle. Ukukhanyisa kwe-Semiconductor kuwuguquko kwezobuchwepheshe kuleli khulu leminyaka. Ngokombono wokuvuthwa kwezobuchwepheshe, kuseyingane. Nakuba ubuchwepheshe bokukhanya okumhlophe kwe-LED enamandla amakhulu buthuthuke ngokushesha, laba abathathu baphila ekuboleni kokukhanya kwe-LED, ukushabalala kokushisa, kanye nezindleko kusengama-LED. I-Tiger Tiger, ukuthandwa nokuthuthukiswa kokukhanyisa. Umthombo wokukhanya we-COB (i-CHIP Ebhodini) uwukulungisa i-chip ngeglue esiliva ku-substrate, futhi indlela yokuxhuma ugesi ye-chip ne-substrate iyasetshenziswa.
