Njengoko izikrini zokubonisa i-LED zisetyenziswa ngokubanzi, abantu baneemfuno eziphezulu zomgangatho wemveliso kunye nemiphumo yokubonisa. Kwinkqubo yokupakisha, itekhnoloji yemveli ye-SMD ayisakwazi ukuhlangabezana neemfuno zokusetyenziswa kwezinye iimeko. Ngokusekelwe kule nto, abanye abavelisi baye batshintsha umkhondo wokupakisha kwaye bakhetha ukuhambisa i-COB kunye nezinye iitekhnoloji, ngelixa abanye abavelisi bakhethe ukuphucula iteknoloji ye-SMD. Phakathi kwabo, iteknoloji ye-GOB iteknoloji ephindaphindiweyo emva kokuphuculwa kwenkqubo yokupakisha ye-SMD.
Ngoko, ngeteknoloji ye-GOB, ngaba iimveliso ze-LED zokubonisa zifikelela kwizicelo ezibanzi? Yiyiphi intsingiselo eya kubonisa uphuhliso lwemarike yexesha elizayo yeGOB? Makhe sijonge!
Ukususela ekuphuhlisweni kweshishini lokubonisa i-LED, kubandakanywa umboniso we-COB, iintlobo ezahlukeneyo zemveliso kunye neenkqubo zokupakisha ziye zavela enye emva komnye, ukusuka kwinkqubo yangaphambili yokufaka (i-DIP), kwinkqubo yokunyuka komhlaba (SMD), ukuvela kwe-COB. itekhnoloji yokupakisha, kwaye ekugqibeleni ukuvela kobuchwepheshe bokupakisha beGOB.
⚪Yintoni iteknoloji yokupakisha yeCOB?
Ukupakishwa kweCOB kuthetha ukuba ibambelela ngokuthe ngqo kwi-chip kwi-PCB substrate ukwenza uqhagamshelo lombane. Injongo yayo ephambili kukusombulula ingxaki yokutshatyalaliswa kobushushu kwizikrini zokubonisa i-LED. Xa kuthelekiswa ne-plug-in ngqo kunye ne-SMD, iimpawu zayo kukugcina indawo, imisebenzi yokupakisha elula, kunye nolawulo olufanelekileyo lwe-thermal. Okwangoku, ukupakishwa kweCOB kusetyenziswa ikakhulu kwezinye iimveliso ezincinci.
Ziziphi iingenelo zetekhnoloji yokupakisha yeCOB?
1. I-Ultra-light and thin: Ngokweemfuno zokwenene zabathengi, iibhodi zePCB ezinobunzima obuyi-0.4-1.2mm zingasetyenziselwa ukunciphisa ubunzima ubuncinane kwi-1/3 yeemveliso zemveli, ezinokunciphisa kakhulu iindleko zezakhiwo, ezothutho nezobunjineli kubathengi.
2. Ukuchasana nokungqubana kunye noxinzelelo loxinzelelo: Iimveliso ze-COB zifakela ngokuthe ngqo i-chip ye-LED kwindawo ye-concave yebhodi ye-PCB, kwaye emva koko sebenzisa i-epoxy resin glue ukuze idibanise kwaye iphilise. Umphezulu wendawo yesibane uphakanyiselwa kwindawo ephakanyisiweyo, egudileyo kwaye inzima, ixhathisa ukungqubana kunye nokugqoka.
3. I-engile enkulu yokujonga: Ipakethe ye-COB isebenzisa ukukhanya okungekho nzulu kwe-spherical ephumayo, kunye ne-engile yokujonga enkulu kune-175 degrees, kufutshane ne-180 degrees, kwaye inomphumela ongcono wokukhanya we-optical diffuse.
4. Ukwazi ukutshabalalisa ubushushu obunamandla: Iimveliso ze-COB zifakela isibane kwibhodi ye-PCB, kwaye zitshintshe ngokukhawuleza ukushisa kwe-wick nge-foil yobhedu kwibhodi ye-PCB. Ukongeza, ubukhulu befoyile yobhedu yebhodi yePCB ineemfuno ezingqongqo zenkqubo, kwaye inkqubo yokutshona kwegolide ayinakubangela ukuthomalalisa ukukhanya okukhulu. Ngoko ke, zimbalwa izibane ezifileyo, eziyandisa kakhulu ubomi besibane.
5. Ukungagugi kwaye kulula ukuyicoca: Umphezulu wendawo yesibane u-convex kwi-spherical surface, egudileyo kwaye ilukhuni, imelana nokungqubana kunye nokugqoka; ukuba kukho inqaku elibi, linokulungiswa kwinqanaba ngenqaku; ngaphandle kwemaski, uthuli lunokucocwa ngamanzi okanye ngelaphu.
6. Iimpawu ezibalaseleyo zemozulu: Yamkela unyango lokukhuselwa kathathu, kunye nemiphumo ebalaseleyo yokungangeni kwamanzi, ukufuma, ukubola, uthuli, umbane ongatshintshiyo, i-oxidation, kunye ne-ultraviolet; idibana neemeko zokusebenza zemozulu yonke kwaye isenokusetyenziswa ngokwesiqhelo kwimeko-bume eyohlukileyo yobushushu obuphakathi kwama-30 degrees ukuya ku-80 degrees.
⚪Yintoni iteknoloji yokupakisha yeGOB?
Ukupakishwa kweGOB bubuchwephesha bokupakisha obuqaliswe ukujongana nemiba yokhuseleko lwamaso ezibane ze-LED. Isebenzisa izinto eziphambili ezicacileyo ukuze zifake i-substrate ye-PCB kunye neyunithi yokupakisha ye-LED ukwenza ukhuseleko olusebenzayo. Kulingana nokongeza umaleko wokukhusela phambi kwemodyuli ye-LED yasekuqaleni, ngaloo ndlela ufezekisa imisebenzi yokukhusela ephezulu kunye nokufezekisa iziphumo zokukhusela ezilishumi ezibandakanya ukungangeni kwamanzi, ubungqina bomswakama, ubungqina bempembelelo, i-bump-proof, i-anti-static, ityuwa yokutshiza-ubungqina. , i-anti-oxidation, i-anti-blue light, kunye ne-anti-vibration.
Ziziphi iingenelo zeteknoloji yokupakisha yeGOB?
1. Iinzuzo zenkqubo ye-GOB: Lukhuselo oluphezulu lwesikrini se-LED esinokufikelela kukhuseleko olusibhozo: ukukhuseleka kwamanzi, ukumanzi, ukungqubuzana, ukungqubuzana, uthuli, ukubola, ukukhanya okuluhlaza okwesibhakabhaka, ukuchasana netyuwa, kunye ne-anti- I-static. Kwaye ayiyi kuba nempembelelo eyingozi ekutshitshiseni ubushushu kunye nokulahleka kokukhanya. Uvavanyo oluqatha lwexesha elide lubonise ukuba ukukhusela iglue kukwanceda ukukhupha ubushushu, kunciphisa izinga le-necrosis yamaso wesibane, kwaye kwenza isikrini sizinze ngakumbi, ngaloo ndlela sandise ubomi benkonzo.
2. Ngokusetyenzwa kwenkqubo ye-GOB, iipikseli zegranular kumphezulu webhodi yokukhanya yoqobo ziye zaguqulwa zaba yibhodi yokukhanya esicaba iyonke, iqonda inguqu ukusuka kwindawo yokukhanya ukuya kwindawo yokukhanya komhlaba. Imveliso ikhupha ukukhanya ngokulinganayo ngakumbi, isiphumo sokubonisa sicacile kwaye sibonakala ngakumbi, kwaye i-angle yokujonga imveliso iphuculwe kakhulu (zombini ngokuthe tye kwaye ngokuthe nkqo inokufikelela phantse kwi-180 °), iphelisa ngokufanelekileyo i-moiré, iphucula kakhulu umahluko wemveliso, ukunciphisa ilitha kunye ne-glare. , kunye nokunciphisa ukudinwa okubonakalayo.
⚪Uthini umahluko phakathi kweCOB kunye neGOB?
Umahluko phakathi kweCOB kunye neGOB ikakhulu kwinkqubo. Nangona iphakheji ye-COB inomgangatho othe tyaba kunye nokhuseleko olungcono kunepakethe ye-SMD yendabuko, iphakheji ye-GOB yongeza inkqubo yokuzalisa iglue phezu kwesikrini, esenza ukuba izibane zesibane se-LED zizinze ngakumbi, kunciphisa kakhulu amathuba okuwa, kwaye unozinzo olomeleleyo.
⚪Yeyiphi enezinto ezilungileyo, COB okanye iGOB?
Akukho mgangatho ongcono, i-COB okanye i-GOB, kuba kukho izinto ezininzi zokugweba ukuba inkqubo yokupakisha ilungile okanye ayikho. Isitshixo kukubona into esiyixabisayo, nokuba kukusebenza kakuhle kwezibane ze-LED okanye ukukhuselwa, ngoko ke iteknoloji yokupakisha nganye ineenzuzo zayo kwaye ayinakwenziwa ngokubanzi.
Xa ngokwenene sikhetha, nokuba sisebenzise ukupakishwa kwe-COB okanye ukupakishwa kwe-GOB kufuneka kuthathelwe ingqalelo kunye nezinto ezibanzi ezifana nendawo yethu yokufakela kunye nexesha lokusebenza, kwaye oku kunxulumene nolawulo lweendleko kunye nesiphumo sokubonisa.
