Inkcazo ye-COB encapsulation
I-COB ibizwa ngokuba yi-Chips kwiBhodi (COB), eyona teknoloji yokusombulula ingxaki yokutshatyalaliswa kobushushu be-LED. Xa kuthelekiswa netekhnoloji ye-in-line kunye ne-SMD, ineempawu ezininzi zokugcina indawo, ukupakishwa okulula, kunye nolawulo olululo lwe-thermal.
I-COB encapsulation, oko kukuthi, i-chip Ebhodini, kukubambelela kwi-chip engenanto kwi-substrate yokudibanisa kunye neglue eqhubayo okanye engaqhubekiyo, kwaye emva koko wenze i-wire bonding ukuze iqonde ukudibanisa kombane. Ukuba i-chip engenanto ibonakaliswe ngokuthe ngqo emoyeni, iyakwazi ukungcoliswa okanye umonakalo owenziwe ngumntu, uchaphazela okanye utshabalalise umsebenzi we-chip, ngoko i-chip kunye nentambo yokudibanisa ifakwe kwi-glue. Le phakheji ikwabizwa ngokuba yi-soft encapsulation.
Izinto eziluncedo zokupakishwa kweCOB
1. I-Ultra-thin: Ngokweemfuno zokwenene zabathengi, ibhodi ye-PCB enobunzima obuvela kwi-0.4-1.2mm ingasetyenziselwa ukunciphisa ubunzima ukuya kwi-1/3 yeemveliso zemveli zemveli, ezinokunciphisa kakhulu i-structural, ukuthutha kunye nobunjineli. iindleko kubathengi.
2. I-Anti-ungquzulwano kunye nokunyanzeliswa: Imveliso ye-COB ifaka ngokuthe ngqo i-chip ye-LED kwindawo yesibane se-concave yebhodi ye-PCB, kwaye iphiliswa yi-epoxy resin. Umphezulu wendawo yesibane u-convex ube ngumphezulu ongqukuva, ogudileyo kwaye uqinile, kwaye uyamelana nokungqubana nokuguga.
3. I-angle enkulu yokujonga: Ipakethe ye-COB isebenzisa ukukhanya okungekho nzulu kwe-spherical, i-angle yokujonga inkulu kune-175 degrees, kufutshane ne-180 degrees, kwaye inomphumo ongcono we-optical diffuse dimming.
4. Ukugoba: Umthamo wokugoba luphawu olulodwa lwendibano yeCOB. Ukugoba kwePCB akubangeli monakalo kwiitshiphusi ze-LED ezigqunyiweyo. Ngoko ke, izikrini ze-arc ze-LED, izikrini zesetyhula, kunye nezikrini ze-wavy zingenziwa ngokulula ngokusebenzisa iimodyuli ze-COB. Yeyona substrate ifanelekileyo kwizikrini ezenzelwe wena kwiibhari kunye neeklabhu zasebusuku. Inokudityaniswa ngokungenamthungo, ulwakhiwo lwemveliso lulula, kwaye ixabiso lisezantsi kakhulu kunescreen esimilise okwe-LED esenziwe yibhodi yesekethe eguquguqukayo kunye nemodyuli yesiko lokubonisa.
5. Ukutshatyalaliswa kokushisa okunamandla: Iimveliso ze-COB zifakwe kwibhodi ye-PCB, kwaye ukushisa kwe-wick kuhanjiswa ngokukhawuleza nge-foil yobhedu kwibhodi ye-PCB. Ubukhulu befoyile yobhedu yebhodi yePCB ineemfuno ezingqongqo zobuchwephesha, kwaye ngenxa yenkqubo yokuntywiliselwa kwegolide, ayibangeli ukuthotywa kokukhanya. Ke ngoko, zimbalwa kakhulu umonakalo we-LED kunye neemveliso zeCOB zandisa kakhulu ubomi.
I-6, iyakwazi ukunxiba, kulula ukuyicoca: umphezulu wendawo yesibane i-convex ibe yindawo engqukuva, egudileyo kwaye iqinile, ayinyangeki kwaye ayinxibi; Ukuba kukho iindawo ezifileyo, unokulungisa iphuzu ngenqaku; akukho maski, uthuli lunokucocwa ngamanzi okanye ngelaphu.
I-7, Iimpawu ezigqwesileyo zemozulu yonke: unyango oluphindwe kathathu lokukhusela, ukungangeni kwamanzi, ubungqina bokufuma, ukuxhathisa ukubola, ukuthintela uthuli, ukugqitywa kwe-anti-static, i-anti-oxidation, impembelelo yokumelana ne-UV ibalasele. Ngoko ke iyakwazi ukuhlangabezana neemeko zokusebenza zemozulu yonke, umahluko wobushushu obuphakathi kwama-30 degrees ukuya ku-zero 80 degrees usenokusetyenziswa ngokuqhelekileyo.
