Ma Nyali Angati Ma LED Angalumikizidwe

Magetsi a mizere ya LED atchuka kwambiri pazaka zambiri, chifukwa cha kuthekera kwawo kupereka mawonekedwe abwino kuchipinda chilichonse kapena malo. Magetsiwa ndi osinthika kwambiri ndipo amatha kugwiritsidwa ntchito pazifukwa zosiyanasiyana, kuphatikiza kuyatsa kamvekedwe ka mawu, kuyatsa ntchito, ndi kuyatsa kumbuyo.

Koma limodzi mwamafunso omwe amafunsidwa pafupipafupi okhudza magetsi amtundu wa LED ndi angati omwe amatha kulumikizana wina ndi mnzake. M'nkhaniyi, tifufuza mwatsatanetsatane funsoli ndikukupatsani zidziwitso ndi malangizo othandiza.

Kumvetsetsa Kuwala kwa Mizere ya LED

Tisanafufuze za kuchuluka kwa magetsi amtundu wa LED omwe angalumikizidwe, choyamba timvetsetse momwe magetsi awa amagwirira ntchito. Monga momwe dzinalo likusonyezera, magetsi a mizere ya LED amapangidwa ndi mizere yayitali ya ma LED (light-emitting diode) omwe amatulutsa kuwala pamene magetsi akudutsa.

Magetsi amenewa nthawi zambiri amagulitsidwa mu ma reel a utali wosiyanasiyana, ndipo amabwera mumitundu yosiyanasiyana komanso milingo yowala. Magetsi amtundu wa LED amakhalanso osinthika kwambiri, zomwe zimapangitsa kuti zikhale zosavuta kuziyika m'malo osiyanasiyana ndi ntchito.

Ndi Nyali Zingati Zowala za LED Zingalumikizidwe?

Kuchuluka kwa nyali zamtundu wa LED zomwe zimatha kulumikizidwa palimodzi zimatengera mphamvu zawo komanso mphamvu yamagetsi awo. Nthawi zambiri, magetsi ambiri a LED amakhala ndi mphamvu ya 12V kapena 24V DC.

Kuti mudziwe kuchuluka kwa magetsi amtundu wa LED omwe angalumikizidwe palimodzi, muyenera kuwerengera kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito pamzere uliwonse ndikuyerekeza ndi mphamvu yamagetsi. Momwe mungachitire izi:

Khwerero 1: Kuwerengera Kugwiritsa Ntchito Mphamvu

Kugwiritsa ntchito mphamvu kwa nyali ya LED kumayesedwa ndi ma watt pa mita (W/m). Kuti muwerengere mphamvu yogwiritsira ntchito chingwe, muyenera kuchulukitsa madzi ake pa mita ndi kutalika kwake.

Mwachitsanzo, ngati muli ndi nyali ya 5-mita ya LED yokhala ndi mphamvu ya 7.2W/m, ndiye kuti mphamvu yonse idzakhala:

Kugwiritsa Ntchito Mphamvu Zonse = 7.2W/mx 5m = 36W

Khwerero 2: Dziwani Kuthekera kwa Magetsi

Mphamvu yamagetsi imayesedwa mu ma volts (V) ndi amps (A). Kuti mudziwe kuchuluka kwa nyali zamtundu wa LED zomwe zitha kulumikizidwa, muyenera kuchulukitsa ma voliyumu ndi ma amperage amagetsi.

Mwachitsanzo, ngati muli ndi magetsi okhala ndi 12V DC ndi 3A, ndiye kuti mphamvu yayikulu kwambiri idzakhala:

Kutulutsa Kwamphamvu Kwambiri = 12V x 3A = 36W

Kuchokera kuwerengera uku, titha kuwona kuti kuchuluka kwa nyali za 5-mita za LED zomwe zimatha kulumikizidwa pamodzi ndi magetsi awa ndi amodzi chifukwa mphamvu yonse yogwiritsira ntchito nyaliyo ndi 36W ndipo imagwirizana ndi kutulutsa kwamphamvu kwamagetsi.

Zinthu Zomwe Zimakhudza Kuchuluka Kwa Magetsi a LED Omwe Angalumikizidwe

Ngakhale kuwerengera pamwambapa ndi chiwongolero chofunikira kuti mudziwe kuchuluka kwa nyali zamtundu wa LED zomwe zitha kulumikizidwa, zinthu zina zingapo zitha kukhudza nambala iyi. Nazi zina mwazifukwa zazikulu:

1. Ubwino Wopereka Mphamvu

Ubwino wa magetsi amatha kukhala ndi gawo lalikulu pakuzindikira kuchuluka kwa nyali zamtundu wa LED zomwe zitha kulumikizidwa. Mphamvu yamagetsi yabwino imakhala ndi mphamvu zokhazikika pakali pano, pomwe yamtundu wotsika imatha kusinthasintha, zomwe zimatsogolera kuzinthu ngati kuwala kapena kuwala kwamagetsi.

Chifukwa chake, ndikofunikira kuti musankhe magetsi apamwamba kwambiri omwe amagwirizana ndi zofunikira za magetsi anu amtundu wa LED.

2. Mtundu wa Kuwala kwa Mzere wa LED

Mtundu wa nyali zamtundu wa LED zomwe muli nazo zimafunikiranso pankhani yolumikiza pamodzi. Zingwe za LED zimagwiritsa ntchito mphamvu zambiri kuposa zina, kotero muyenera kuwonetsetsa kuti magetsi ali ndi mphamvu zokwanira kuti akwaniritse zomwe akufuna.

Kuphatikiza apo, kutentha kwamtundu ndi kuwala kwa nyali za LED kumatha kukhudzanso kuchuluka kwa mizere yomwe mungalumikizane nayo, chifukwa mitundu yosiyanasiyana ndi milingo yowala nthawi zambiri imakhala ndi mavoti amphamvu osiyanasiyana.

3. Wiring

Mawaya omwe amalumikiza nyali za mizere ya LED kumagetsi amathanso kukhudza mphamvu zonse. Ngati mawayawo sali wandiweyani mokwanira, angayambitse kutsika kwa magetsi, zomwe zingayambitse magetsi kuzimitsa kapena kuzima.

Chifukwa chake, muyenera kugwiritsa ntchito waya woyezera woyezera kutengera mphamvu za magetsi anu amtundu wa LED.

4. Utali wa Nyali Zowala za LED

Kutalika kwa nyali zamtundu wa LED kumathandizanso kudziwa kuti ndi angati angalumikizidwe. Zingwe zazitali zimakonda kugwiritsa ntchito mphamvu zambiri, kotero muyenera kuwonetsetsa kuti magetsi ali ndi mphamvu zokwanira kuti agwire.

Komanso, ngati muli ndi zingwe zazifupi zingapo, mutha kuzilumikiza motsatizana kapena zofananira kuti mukwaniritse kutalika komwe mukufuna, koma izi zingafunike mawaya owonjezera kapena zolumikizira.

5. Zinthu Zachilengedwe

Pomaliza, zinthu zachilengedwe monga kutentha, chinyezi, ndi fumbi zitha kukhudzanso magwiridwe antchito a magetsi anu amtundu wa LED komanso kugwiritsa ntchito mphamvu zawo. Mwachitsanzo, ngati kutentha kuli kwakukulu, kungayambitse magetsi kutenthedwa, zomwe zimapangitsa kuti mphamvu zichepetse komanso kuwononga magetsi.

Mapeto

Ndiye, ndi magetsi angati amtundu wa LED omwe angalumikizidwe? Yankho limatengera zinthu zingapo, kuphatikiza mphamvu zamagetsi, mtundu wa kuwala kwa Mzere wa LED, waya, kutalika, ndi chilengedwe.

Potsatira malangizo omwe tapereka ndikuganiziranso izi, mutha kuwonetsetsa kuti mukulumikiza nambala yoyenera ya nyali zamtundu wa LED mosamala komanso moyenera. Kaya mukuyang'ana kuti muwongolere bwino nyumba yanu kapena kukulitsa malo anu ogwirira ntchito, nyali za mizere ya LED zimapereka njira yowunikira komanso yowoneka bwino yomwe ingasangalatse.
