Ndi kusinthika kosalekeza ndi kuwongolera kwaukadaulo wa LED, zowonera zotsatsa zakunja zochulukirachulukira zikusintha kuchokera ku zazikulu kupita zazing'ono, kuyambira zazing'ono mpaka zomveka. M'makampani owonetsera ma LED, zowonetsera zakunja zotsatsa zakunja ndizopangidwa pamwamba. Zowonetsera za LED zokwezedwa panja zimagwiritsa ntchito tchipisi tapamwamba kwambiri zotulutsa kuwala ngati chinthu chachikulu, ndipo ma driver apamwamba a IC ndi ma LED amitundu yonse. Kuchulukirachulukira, ngodya yowonera, kukhazikika, kufanana kwamitundu, kuchulukira kwamitundu, kukwanira kwa m'mphepete mwazithunzi, makanema osalala, ndi zina zambiri.Shenzhen Xinyiguangamagwiritsa ntchito mikanda ya nyali ngati sing'anga kusanthula mikanda yambiri yokwera pamwamba yomwe imagwiritsidwa ntchito panja pamsika.
▲ Panja pamwamba pa phiri lodzaza guluu
Mkanda woyamba wa nyali ndi SMD2828, ndipo mitundu yomwe ingagwiritse ntchito pazowonetsera zotsogola ndiPanja pamwamba phiri P5, P6, P6.25ndi zitsanzo zina zakunja. Zogulitsa zakunja sizimangokhala pazitsanzo zitatuzi. Palinso zowonetsera zakunja zobwereka P6.67 ndi zowonetsera pansi matailosi P7.8125 ndi P8.928, zomwe ndi zoimira zopangira ntchito zakunja ndi ntchito za siteji. Kukula kwa mawonekedwe a SMD2828 ndi 3.0 × 3.0 × 2.4mm, ndipo mawonekedwe apadera osalowa madzi amawongolera bwino ntchito yotsimikizira chinyezi. Pakudzaza zomatira zopanda madzi, gelisi yapadera ya silika yomata panja imagwiritsidwa ntchito. Makulidwe a guluu ndi 1.5mm, omwe amalekanitsa bwino madzi amvula kuti asawononge bolodi la PCB, kuteteza zinthu zoyipa monga mabwalo amfupi.
Mtundu wachiwiri ndi SMD3535. Kukula kwa nyali ya 3535 ndi yayikulupo kuposa ya 2828, ndipo kukula kwake ndi 3.5 × 3.5 × 2.8mm mu makulidwe. Zowonetsera zakunja zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala ndi mawonekedwe akunja a P8 okhala ndi utoto wamitundu yonse komanso mawonekedwe akunja a P10. Chifukwa cha mikanda yokulirapo ya nyali, kugwiritsa ntchito m'munda wakunja kwapamwamba kumakhala kocheperako kuposa 2828. 3535 imatenga mapangidwe oyera mkati ndi kunja kwakuda, omwe amathandizira kwambiri kusiyanitsa. Njira yodzaza zomatira yopanda madzi imagwiritsanso ntchito silikoni yapadera pazomata zakunja, ndipo makulidwe a guluu ndi 1.5mm.
▲ Chithunzi cha module yodzaza ndi zomatira
Chiwonetsero cha P8led chakunja ndi mawonekedwe a P10led ali ndi mtunda waukulu pakati pawo. Pogwiritsa ntchito mikanda ya nyale 3535 ndi mikanda yokwera pamapazi apamwamba, makina odzaza guluu amatha kuthetsa vutoli. Komabe, P5, P6, ndi P6.25 ali ndi zofunikira zolondola kwambiri pakuchita. Ngati simudziwa bwino ukadaulo wodzaza guluu, zikhudza mawonekedwe ndi kusasinthika kwa chinsalu chonse. Shenzhen Xinyiguang wachita ntchito zambiri pankhaniyi, kuthetsa vuto la mawonekedwe osawoneka bwino omwe amayamba chifukwa cha njira yodzaza ndi guluu panja.
