Ebintu bino ebinyweza bitera okwetaaga abavuzi ba kasasiro obutakyukakyuka okukakasa nti kasasiro atereezebwa bulungi, ekintu ekikulu ennyo okusobola okufuluma obutakyukakyuka n’okwesigamizibwa. Nga balondawo baddereeva ezikwatagana n’ebiragiro ebiriwo kati ebya buli ttaala, pulojekiti esobola okutuuka ku mutindo oguteeberezebwa mu ssaawa eziwanvu ez’okukola, okukendeeza ku bwetaavu bw’okuddaabiriza n’okwongera ku bulamu bw’enkola y’amataala.
Eky’okulabirako C: Okusiiga amataala ku ffaasi ebweru (pulojekiti y’okumasamasa ebweru) .
Ekintu kya LED: Ebitaala eby’amaanyi amangi
Ekyetaagisa: Okuziyiza amazzi n’obutafaali obuziyiza amazzi agakulukuta
Okuteesa: Ddereeva za kasasiro ezitakyukakyuka ez’amaanyi amangi nga zirina obukuumi obw’amaanyi okuva ku mazzi n’ekipimo kya IP/obutonde ekituufu
Pulojekiti z’okutaasa ebweru, gamba ng’okutaasa mu maaso oba okutaasa ku nguudo, zitera okuzingiramu amataala ag’amaanyi amangi agalina okugumira embeera z’obutonde enkambwe. Baddereeva bano balina okuba nga basobola okugumira amasannyalaze agakulukuta n’okubeera mu mbeera y’obudde. N’olwekyo, ddereeva wa masanyalaze agatali gakyukakyuka ow’amaanyi amangi ng’alina ebikuuma eby’amaanyi okuva ku masannyalaze n’ekipimo kya IP ekituufu kyetaagisa. Kino kikakasa nti enkola y’amataala esigala ng’ekola era nga yeesigika wadde nga waliwo okusoomoozebwa okuva mu bifo eby’ebweru, ng’okuwangaala kwe kusinga obukulu.
Olukalala lw'okukebera: Engeri y'okulondamu Ddereeva wa LED omutuufu (Ekikozesebwa mu kusalawo amangu)
Kozesa olukalala luno okukakasa nti olonze ddereeva wa LED omutuufu nga tonnaba kuteeka order oba okufulumya Bill of Materials (BOM):
Ekika ky’omugugu: Laba oba okola ne LED strip/module (ekyetaagisa constant voltage, CV) oba luminaire (ekyetaagisa constant current, CC).
Voltage efuluma: Laba ekifulumizibwa ekyetaagisa —oba 12V DC oba 24V DC ku vvulovumenti etakyukakyuka (CV), oba mA egereddwa ku kasasiro atakyukakyuka (CC).
Power Sizing: Bala wattage yonna eyeetaagisa era osseeko 20% headroom okukakasa nti ekola eyeesigika n’okusikiriza enkyukakyuka yonna.
Okukwatagana n’okuzibikira: Kakasa oba weetaaga okuzikira TRIAC, ELV, MLV, oba 0–10V. Kakasa nti ddereeva gw’olonze akwatagana n’enkola yo ey’okuzibikira.
Enneeyisa y’omugugu omutono: Kakasa nti ddereeva asobola okukola mu ngeri enywevu mu bbanga erisuubirwa naddala ku mbeera z’omugugu omutono.
Embeera y’obutonde: Kebera embeera y’okussaako era okakasizza ebipimo ebyetaagisa —ebikalu, ebinnyogovu, oba ebibisi —wamu n’ebipimo byonna ebyetaagisa ebya IP n’ebyetaago by’okuzibikira.
Obukuumi n’okugoberera: Kakasa nti ddereeva atuukiriza omutindo gw’obukuumi ogukwatagana, nga UL/cUL, era agoberera ebisaanyizo bya Class 2 we kiba kituufu, ng’oggyeeko omutindo gwonna ogw’enjawulo ogwa pulojekiti.
Nga tonnagula, kakasa ekika ky’omugugu gwa LED, obwetaavu bw’okufulumya, wattage yonna n’ekifo ky’omutwe, enkola ya dimming ekwatagana, n’okugereka obutonde. Ensobi ezisinga obungi mu kulonda zibaawo ng’ekimu ku bino kibuukiddwa —naddala okuzibikira okukwatagana n’enneeyisa y’omugugu omutono ku pulojekiti entonotono.
Mu bufunzi
Okulonda ddereeva wa LED omutuufu / amasannyalaze ga LED gwe musingi gw’enkola y’okutaasa LED eyesigika. Okulonda okusinga obulungi bulijjo y’eyo ekwatagana n’ekika ky’omugugu gwo ogwa LED (constant voltage vs constant current), ekwatagana n’enkola yo ey’okufuga (nga TRIAC dimming), era ewereddwa embeera y’okussaako mu nsi entuufu.
Bw’otwala ddereeva ng’ekitundu ky’amasannyalaze ekikulu —so si ekintu ekiyambako —okendeeza ku kwemulugunya kw’okumasamasa, weewala okubuguma ennyo, oyita mu kukeberebwa mu ngeri ennungi, era okuuma ssente z’ossaamu amataala okumala emyaka.
Okulambuula Suretron 's range of transformers okuzuula eky'okugonjoola ekituufu ku byetaago byo eby'okutaasa LED.
