Ngokusungulwa okuqhubekayo kanye nokuthuthukiswa kobuchwepheshe be-LED, izikrini zokukhangisa zangaphandle ziya ngokuya zishintsha kusukela kwezinkulu ukuya kwezincane, futhi kusukela kwezincane kuya ezicacile. Embonini yokubonisa i-LED, izikrini zokukhangisa zangaphandle ezinencazelo ephezulu zangaphandle ziyimikhiqizo ebekwe phezulu. Izibonisi ze-LED ezibekwe ngaphandle zisebenzisa ama-chips akhipha ukukhanya ekhwalithi ephezulu njengento eyinhloko, futhi ama-IC abashayeli bekhwalithi ephezulu ayizibonisi ze-LED ezinombala ogcwele. Ukuminyana okuphezulu, i-engeli yokubuka, ukuzinza, ukufana kombala, ukugcwaliswa kombala, ukucoleka konqenqema lwesithombe, imiphumela yevidiyo ebushelelezi, njll. kunikeze ukudlala okuphelele ezinzuzweni eziyinhloko zezikrini zokukhangisa eziholwa ngaphandle.Shenzhen Xinyiguangisebenzisa ubuhlalu besibani njengendlela yokuhlaziya ubuhlalu besibani obubekwe ngaphezulu obuvame ukusetshenziswa ngaphandle emakethe.
▲ Umdwebo wenqubo yokugcwalisa iglue yangaphandle
Ubuhlalu besibani bokuqala yi-SMD2828, futhi amamodeli engawasebenzisa kusibonisi esiholayo yiwointaba yangaphandle ye-P5, P6, P6.25namanye amamodeli angaphandle. Imikhiqizo yangaphandle ayinqunyelwe kulawa mamodeli amathathu. Kukhona nezikrini eziqashiswayo zangaphandle P6.67 kanye nezikrini zamathayela aphansi P7.8125 kanye ne-P8.928, okuyimikhiqizo emele izinhlelo zokusebenza zangaphandle nezinhlelo zokusebenza zasesiteji. Usayizi wokubukeka we-SMD2828 ngu-3.0 × 3.0 × 2.4mm, futhi umklamo okhethekile wesakhiwo esingangeni manzi uthuthukisa ngempumelelo umsebenzi wokuvikela umswakama. Enqubweni yokugcwalisa i-glue engangeni manzi, ijeli ye-silica ekhethekile yezitika zangaphandle zangaphandle ziyasetshenziswa. Ubukhulu beglue bungu-1.5mm, obuhlukanisa ngokuphumelelayo amanzi emvula ekuguguleni ibhodi le-PCB, ukuvimbela izici ezingezinhle ezifana neziyingi ezimfushane.
Uhlobo lwesibili yi-SMD3535. Ubukhulu bobuhlalu besibani obungu-3535 bukhulu kakhulu kunobuka-2828, futhi ubukhulu bokubukeka bungu-3.5×3.5×2.8mm ngobukhulu. Izibonisi zangaphandle ezivame ukusetshenziswa zifaka isibonisi esinemibala egcwele ye-P8 ebekwe ngaphandle kanye nesibonisi esinombala ogcwele se-P10. Ngenxa yobuhlalu besibani obukhulu, uhlelo lokusebenza kunkambu yencazelo ephezulu yangaphandle luncane kakhulu kunalolo luka-2828. I-3535 yamukela idizayini yokumhlophe ngaphakathi nangaphandle emnyama, okuthuthukisa kakhulu umphumela wokugqama. Inqubo yokugcwalisa iglue engangeni manzi isebenzisa i-silicone ekhethekile yezitika zangaphandle, futhi ubukhulu beglue buyi-1.5mm.
▲ Umdwebo wemodyuli ogcwele isinamathiseli
Isibonisi se-P8led esibekwe ngaphandle nesibonisi se-P10led sinebanga elikhulu phakathi kwakho. Ukusebenzisa ubuhlalu bezibani be-3535 kanye nobuhlalu bezibani eziphakeme ezinyaweni, umshini ojwayelekile wokugcwalisa iglue ungaxazulula inkinga. Nokho, i-P5, i-P6, ne-P6.25 inezidingo zokunemba eziphakeme kakhulu kule nqubo. Uma ungazi kahle ubuchwepheshe bokugcwalisa iglue, kuzothinta ukubukeka nokuvumelana kwesikrini sonke. U-Shenzhen Xinyiguang wenze umsebenzi omningi kulokhu, ukuxazulula ngokuphelele inkinga yesikrini esifiphele esibangelwa inqubo yokugcwalisa i-glue yangaphandle.
