Kodi Kuwala kwa Mzere wa LED ndi chiyani?
Kuwala kwa mizere ya LED ndi mitundu yatsopano komanso yosunthika yowunikira.Pali mitundu yosiyanasiyana komanso kuchotserapo, koma nthawi zambiri, ali ndi izi:
● Amakhala ndi ma emitter ambiri a LED omwe amayikidwa pa bolodi yopapatiza, yosinthika
● Gwiritsani ntchito magetsi otsika kwambiri a DC
● Amapezeka mumitundu yosiyanasiyana yokhazikika komanso yosinthika komanso yowala
● Kutumiza mu reel yaitali (yomwe nthawi zambiri imakhala mamita 16 / 5), imatha kudulidwa mpaka kutalika, ndipo imakhala ndi zomatira za mbali ziwiri zoyikapo.
Anatomy ya chingwe cha LED
Nyali ya LED imakhala ndi theka la inchi (10-12 mm) m'lifupi, mpaka 16 mapazi (5 metres) kapena kupitilira apo.Amatha kudulidwa mpaka kutalika kwake pogwiritsa ntchito lumo limodzi ndi ma cutlines, omwe ali mainchesi 1-2.
Ma LED omwe ali pawokha amayikidwa pambali pa mzerewu, nthawi zambiri amakhala ndi ma LED 18-36 pa phazi (60-120 pa mita).Kuwala kwamtundu ndi mtundu wa ma LED omwewo amatsimikizira mtundu wonse wa kuwala ndi mtundu wa mzere wa LED.
Kumbuyo kwa mzere wa LED kumaphatikizapo zomatira zambali ziwiri zomwe zidayikidwa kale.Ingochotsani chingwecho, ndikuyika mzere wa LED pamalo aliwonse.Chifukwa bolodiyi idapangidwa kuti ikhale yosinthika, mizere ya LED imatha kuyikidwa pamalo opindika komanso osafanana.
Kuzindikira Kuwala kwa Mzere wa LED
Kuwala kwa mizere ya LED kumatsimikiziridwa pogwiritsa ntchito metriclumens.Mosiyana ndi mababu a incandescent, mizere yosiyanasiyana ya LED imatha kukhala ndi magwiridwe antchito osiyanasiyana, chifukwa chake kuwunika kwamadzi sikutanthauza nthawi zonse pozindikira kutulutsa kwenikweni kwa kuwala.
Kuwala kwa mizere ya LED kumafotokozedwa mu lumens pa phazi (kapena mita).Mzere wabwino wa LED uyenera kupereka ma lumens 450 pa phazi limodzi (1500 lumens pa mita), yomwe imapereka pafupifupi kuchuluka kofanana kwa kuwala kofanana ndi phazi limodzi ngati nyali ya T8 ya fulorosenti.(Mwachitsanzo 4-ft T8 fluorescent = 4-ft ya LED strip = 1800 lumens).
Kuwala kwa mizere ya LED kumatsimikiziridwa ndi zinthu zitatu:
● Kuwala kwa kuwala ndi mphamvu pa LED emitter
● Chiwerengero cha ma LED pa phazi lililonse
● Kujambula kwamphamvu kwa mzere wa LED pa phazi
Kuwala kwa mzere wa LED wopanda mawonekedwe owala mu lumens ndi mbendera yofiira.Mufunikanso kuyang'anira mizere yotsika mtengo ya LED yomwe imati yowala kwambiri, chifukwa imatha kuyendetsa ma LED mpaka kulephera msanga.
Kachulukidwe ka LED & Kujambula Mphamvu
Mutha kukumana ndi mayina osiyanasiyana amtundu wa LED monga 2835, 3528, 5050 kapena 5730. Osadandaula kwambiri ndi izi, chifukwa chomwe chili chofunikira kwambiri mumzere wa LED ndi kuchuluka kwa ma LED pa phazi lililonse, ndikujambula mphamvu pa phazi lililonse.
Kachulukidwe ka LED ndi kofunikira pozindikira mtunda pakati pa ma LED (pitch) komanso ngati padzakhala malo owoneka bwino komanso madontho amdima pakati pa zotulutsa za LED.Kuchuluka kwa ma LED 36 pa phazi lililonse (ma LED 120 pa mita) nthawi zambiri kumapereka kuyatsa kwabwino kwambiri, kugawika kofananako.Ma emitters a LED ndi gawo lokwera mtengo kwambiri pakupanga Mzere wa LED, choncho onetsetsani kuti mumawerengera kusiyana kwa kachulukidwe ka LED poyerekeza mitengo ya Mzere wa LED.
Kenaka, ganizirani mphamvu ya kuwala kwa kuwala kwa LED pa phazi lililonse.Kujambula kwa magetsi kumatiuza kuchuluka kwa mphamvu zomwe dongosololi lidzagwiritse ntchito, kotero izi ndizofunikira kuti mudziwe mtengo wamagetsi anu ndi zofunikira zamagetsi (onani pansipa).Mzere wabwino wa LED uyenera kupereka ma watts 4 pa phazi kapena kupitilira apo (15 W / mita).
Pomaliza, yang'anani mwachangu kuti muwone ngati ma LED akuyendetsedwa mopitilira muyeso pogawa madzi pa phazi limodzi ndi kachulukidwe ka LED pa phazi.Pazinthu zamtundu wa LED, nthawi zambiri zimakhala chizindikiro chabwino ngati ma LED sayendetsedwa mopitilira 0.2 watts iliyonse.
Zosankha za Mtundu wa Mzere wa LED: Zoyera
Magetsi a mizere ya LED amapezeka mumitundu yosiyanasiyana yoyera kapena mitundu.Nthawi zambiri, kuwala koyera ndiye njira yothandiza komanso yotchuka kwambiri pakuwunikira m'nyumba.
Pofotokoza mithunzi yosiyana ndi mikhalidwe yoyera, kutentha kwa mtundu (CCT) ndi index rendering index (CRI) ndi ma metric awiri omwe ndi ofunikira kukumbukira.
Kutentha kwamtundu ndi muyeso wa momwe kuwalako kumawonekera "kutentha" kapena "kuzizira".Kuwala kofewa kwa bulb yachikhalidwe kumakhala ndi kutentha kwamtundu wocheperako (2700K), pomwe kuwala kowala, koyera kowala masana kumakhala ndi kutentha kwamitundu yambiri (6500K).
Kumasulira kwamitundu ndi muyezo wa momwe mitundu yolondola imawonekera pansi pa gwero la kuwala.Pansi pa chingwe chochepa cha CRI LED, mitundu ingawoneke yopotoka, yotsukidwa, kapena yosazindikirika.Zida zapamwamba za CRI LED zimapereka kuwala komwe kumapangitsa kuti zinthu ziziwoneka momwe zingakhalire pansi pa gwero lowala bwino monga nyali ya halogen, kapena masana achilengedwe.Yang'ananinso mtengo wa R9 wowunikira, womwe umapereka zambiri za momwe mitundu yofiira imapangidwira.
Zosankha za Mtundu wa Mzere wa LED: Mtundu Wokhazikika komanso Wosinthika
Nthawi zina, mungafunike nkhonya, zodzaza mtundu.Pazifukwa izi, mikwingwirima yamitundu ya LED imatha kumveketsa bwino komanso kuyatsa kwamasewera.Mitundu yamitundu yonse yowoneka ikupezeka - yofiirira, yabuluu, yobiriwira, amber, yofiira - ngakhale ultraviolet kapena infrared.
Pali mitundu iwiri yayikulu ya mizere yamtundu wa LED: mtundu umodzi wokhazikika, ndikusintha mtundu.Mzere wokhazikika wa LED umatulutsa mtundu umodzi wokha, ndipo mfundo yogwiritsira ntchito ili ngati mizere yoyera ya LED yomwe takambirana pamwambapa.Mzere wa LED wosintha mtundu umakhala ndi ma tchanelo amitundu angapo pamzere umodzi wa LED.Mtundu wofunikira kwambiri umaphatikizapo njira zofiira, zobiriwira ndi zabuluu (RGB), zomwe zimakulolani kusakaniza mitundu yosiyanasiyana yamitundu pa ntchentche kuti mukwaniritse mtundu uliwonse.
Ena amalola kuwongolera kosinthika kwa kutentha kwamitundu yoyera kapena kutentha kwamitundu yonse ndi mitundu ya RGB.
Input Voltage & Power Supply
Ma LED ambiri amapangidwa kuti azigwira ntchito pa 12V kapena 24V DC.Mukachoka pa gwero lamagetsi la mains mains (mwachitsanzo, khoma lanyumba) pa 120/240V AC, mphamvuyo iyenera kusinthidwa kukhala siginecha yoyenera ya DC yotsika.Izi zimachitika pafupipafupi komanso zimatheka pogwiritsa ntchito magetsi a DC.
Onetsetsani kuti magetsi anu akukwaniramphamvu mphamvukuyatsa mizere ya LED.Mphamvu iliyonse yamagetsi ya DC imalemba mndandanda wake wapamwamba kwambiri (mu Amps) kapena mphamvu (mu Watts).Tsimikizirani kuchuluka kwa mphamvu zonse za mzere wa LED pogwiritsa ntchito njira iyi:
● Mphamvu = Mphamvu ya LED (maft) x kutalika kwa mzere wa LED (mu ft)
Chitsanzo cholumikiza 5 ft ya mzere wa LED pomwe kugwiritsa ntchito mphamvu kwa mzere wa LED ndi 4 Watts pa phazi:
● Mphamvu = 4 Watts pa ft x 5 ft =20 Watts
Mphamvu yojambulira pa phazi lililonse (kapena mita) imakhala pafupifupi nthawi zonse imalembedwa muzolemba zamtundu wa LED.
Simukudziwa ngati muyenera kusankha pakati pa 12V ndi 24V?Zina zonse zofanana, 24V nthawi zambiri ndiye kubetcha kwanu kopambana.
