Ngati muli ndi bajeti yayikulu ndipo mukufuna kukhazikitsa mwaukadaulo, pitani pa DMX512 mizere ya LED yoyankhidwa. Protocol yodziwika padziko lonse lapansi ikulitsa kusinthasintha pakuphatikiza makina anu ndi zida za chipani chachitatu. Kupatula apo, mu DMX512, ma siginecha osinthika amatumizidwa limodzi. Chifukwa chake, ngati LED imodzi yawonongeka, inayo siyikhudza magwiridwe ake. Iwo ndi abwino kwa zisudzo, siteji, konsati, chochitika, chionetsero, mafilimu, ndi kuunikira kupanga.
Komabe, gulani zingwe za LED za SPI ngati mukufuna kuwongolera bwino ma LED. Amakulolani kuti muwongolere kuwala kwamtundu ndi zotsatira za mzere uliwonse wa LED pa PCB. Izi zimawapangitsa kukhala abwino pazikwangwani zama digito, ma TV & kuwunika kuphatikizika, kuyatsa zojambulajambula, ndi zina zambiri. Kukhazikitsa kosavuta komanso kwachangu kumawapangitsa kukhala oyenera ma projekiti a DIY.
Chilichonse chomwe mungasankhe DMX512 ndi mizere ya LED ya SPI, LEDYi ndiye mtheradi wanu wopereka mizere ya LED. Tikukupatsirani malo osinthira makonda onse awiri. Titha kupereka zowongolera za LED yokhala ndi IP52(zopaka silicone), IP65(silicone chubu), IP65H(chubu chotsitsa kutentha), IP67(silicone filling), IP67E(silicone extrusion), IP68(PU encased) kapena chilichonse malinga ndi zosowa zanu. Timaperekanso zida zosinthira makonda azinthuzi, kugwiritsa ntchito mphamvu, kukula, mawonekedwe, kutalika, ndi kulongedza. Ndiye mudikirenji motalikirapo? Lumikizanani nafe ASAP!
