Nze nneebuuza oba waliwo omuntu yenna asisinkanye embeera nga 'amasannyalaze ga dimming ge wagula tegazikira', amataala gali oba mu bujjuvu oba mu bujjuvu, era omuwendo gw'enkyukakyuka gusukkiridde okusaasaanya! Tofaayo singa osisinkana embeera eno eswaza, leka SureTron , efulumya ebweru mu mawanga agasukka mu 100 okwetoloola ensi yonna, ekuwe amagezi. Nga omukugu mu kukola amasannyalaze ag’amagezi aga Dimming, tufunze eby’okugonjoola ebikulu bitaano ebikuyamba okugonjoola amangu amasannyalaze okulemererwa!
Oyinza okuba nga wagula amasannyalaze agatali ga ddereeva .
Tulina okusooka okunnyonnyola endowooza. Si buli ddereeva power supplies nti zirina dimming functions. Dimming driver power supply eriko module ya dimming protocol, esobola okutereeza mu ngeri ey’amaanyi vvulovumenti efuluma oba akasannyalazo akafuluma okusinziira ku bubonero obw’ebweru okutuuka ku bbugumu oba okutereeza ebbugumu lya langi n’okutereeza langi. Naye, dizayini ya circuit y’amasannyalaze ga ddereeva agatali ga kuzikira nnyangu, era egoberera ebifulumizibwa ebinywevu byokka. Amataala gali mu bujjuvu oba mu bujjuvu. N’olwekyo, bw’osanga amasannyalaze agatali ga ddereeva agatali gakulukuta, kiyinzika okuba nti oguze ekintu ekikyamu.
Kiyinza okuba nti enkola ya dimming tekwatagana na .
Bw’ogula amasannyalaze aga ddereeva agazikira, naye nga n’enkola ya dimming tekwatagana, n’okutuusa kati tezikira. Okugeza, thyristor dimmer + 0-10V dimming power supply = tesobola kuzikira, kubanga ebika bya siginiini bya protocol ebbiri bya njawulo, Thyristor dimmer is phase cutting, 0-10V dimming power supply is analog voltage, just like two people communicating in different languages, they can’t reach a consunsus at all.
Kiyinza okuba nti ettaala yennyini tewagira dimming .
Singa ettaala kasitoma gy’akozesa tewagira kuzikira, olwo ne bwe kiba nti amasannyalaze agazikira gakyusibwa, ekintu ekizikira tekijja kuba kirungi nnyo, oba wadde tekisobola kuzikira.
Kiyinza okuba nti ekika ky’amasannyalaze agazikira tekirondeddwa bulungi .
Sooka otegeere oba ettaala ya LED ya ttaala ya vvulovumenti etakyukakyuka oba ettaala ya kasannyalazo etakyukakyuka. Ettaala za LED eza vvulovumenti ezitakyukakyuka (ezitera okubeera 12V, 24V) zeetaaga okukwatagana n’amasannyalaze agatali gakyukakyuka aga vvulovumenti, amataala ga LED agatali gakyukakyuka (aga bulijjo 350mA-2000mA) Kozesa amasannyalaze agatali ga bulijjo agakulukuta. Singa ekika ky’amasannyalaze agazikira tekirondebwa bulungi, enkola ya normal dimming tesobola kukolebwa.
Kiyinza okuba nti amaanyi g’amasannyalaze agazikira tegakwatagana na maanyi ga nsibuko ya kitangaala .
Singa amasannyalaze g’amasannyalaze agazikira n’ensibuko y’ekitangaala tebikwatagana, amasannyalaze agazikira gajja kuva ku mulimu, era wajja kubaawo ebizibu nga okuzikira okuwuuma n’okumasamasa okusinga wansi tebisobola kuzikira. N’olwekyo, nga tetunnaba kugula masannyalaze ga kuzimba, tulina okubala amasannyalaze amatuufu ag’ettaala n’oluvannyuma ne tulonda amasannyalaze agagereddwa ag’amasannyalaze: Amasannyalaze agazikira Amasannyalaze agagereddwa = Amasannyalaze gonna awamu ag’ettaala x1.2.
Okusobola okwongera ku bulamu bw’amasannyalaze agazikira, kitera okusemba abakola amataala okuddukanya amasannyalaze agazikira ku bitundu 80% ku mugugu ogugereddwa, ekiyinza okulongoosa obutebenkevu bw’amasannyalaze.
Singa ebizibu ebyo waggulu bikakasiddwa, era ng’ettaala yo ekyasobola okutuuka ku mulimu gw’okuzikira, oyinza okulowooza oba waliwo ekizibu ku mitendera gya waya? Olw’okuba singa layini y’okuzikira (dimming line) teyungiddwa bulungi oba akabonero akazikira kataataaganyizibwa, omulimu gw’okuzikira gujja kulemererwa, era waya ezitali za bulijjo nazo zijja kuleeta obuzibu mu by’okwerinda, kale waya z’amasannyalaze agazikira zirina okugoberera ennyo ekitabo ky’ebintu.
Okusobola okutuuka ku smooth dimming effect, nga tugula amasannyalaze, tulina okusooka okunnyonnyola ebyetaago byaffe, okulonda amasannyalaze agazikira agakwatagana n’ettaala, era jjukira okugateeka n’okugakozesa mu ngeri enkakali okusinziira ku kitabo, olwo omulimu gw’okuzikira kw’ettaala gusobole okukozesebwa mu ngeri eya bulijjo.
