Momwe Magetsi a Led Strip Amagwirira Ntchito

Kodi Kuwala kwa Mzere Wa LED Kumagwira Ntchito Motani?

Magetsi amtundu wa LED akhala gawo lofunikira pakuwunikira kwamakono ndipo amagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza kuyatsa kwamkati, kuyatsa kokongoletsa, komanso ngakhale pazida zamagetsi. Magetsi a mizere ya LED amakondedwa kuposa matekinoloje akale owunikira chifukwa ndiopanda mphamvu komanso amakhala ndi moyo wautali. Koma zimagwira ntchito bwanji? Tiyeni tifufuze.

Kodi Kuwala kwa Mzere wa LED Ndi Chiyani?

Magetsi amtundu wa LED amapangidwa ndi nyali zamtundu wa LED zomwe zimakonzedwa motsatizana ndipo zimayikidwa pa bolodi losinthika. Bolodi lozungulira nthawi zambiri limakhala ndi tepi yomatira kumbuyo, zomwe zimapangitsa kuti zikhale zosavuta kuziyika. Kuwala kwa mizere ya LED kumabwera muutali wosiyanasiyana, mitundu, ndi milingo yowala, kuwapangitsa kukhala osinthasintha pazosowa zosiyanasiyana zowunikira.

Kodi Kuwala kwa Mzere Wa LED Kumagwira Ntchito Chiyani?

Kuwala kwa mizere ya LED kumagwira ntchito potengera mfundo ya electroluminescence. Electroluminescence ndi chodabwitsa chomwe kuwala kumachokera kuzinthu pamene kuyikidwa kumunda wamagetsi. Ma LED amapangidwa ndi zinthu za semiconductor, nthawi zambiri gallium arsenide, yomwe imatulutsa mphamvu ngati kuwala ikayikidwa pamagetsi.

Kodi Kuwala kwa Mzere Wa LED Kumapanga Bwanji Mtundu?

Magetsi amtundu wa LED amatha kutulutsa mitundu yosiyanasiyana kudzera munjira yotchedwa kusanganikirana kwamitundu. Kusakaniza mitundu kumaphatikizapo kuphatikiza magetsi amitundu yosiyanasiyana kuti apange mtundu womwe mukufuna. Magetsi amtundu wa LED amatha kupanga mitundu yosiyanasiyana pogwiritsa ntchito ma RGB kapena RGBW LED.

Ma RGB LED ali ndi mitundu itatu, yofiira, yobiriwira, ndi yabuluu, yomwe, ikaphatikizidwa mosiyanasiyana, imatha kupanga pafupifupi mtundu uliwonse. Ma LED a RGBW, mbali ina, ali ndi ma LED Ofiira, Obiriwira, Abuluu, ndi Oyera, omwe amatha kupanga mitundu yoyera komanso yowala. Magetsi a RGBW LED amawakonda pazinthu zofunikira kwambiri monga kujambula ndi mavidiyo.

Kodi Kuwala kwa Mizere ya LED Kumapanga Bwanji Kuwala?

Kuwala kwa mizere ya LED kumatulutsa kuwala kudzera mu ma photon. Pamene magetsi akuyenda kudzera mu kuwala kwa LED, amasangalatsa ma electron muzinthu za semiconductor, kuwapangitsa kuti atulutse mphamvu mu mawonekedwe a photons. Kenako ma photon amatulutsa kuwala komwe kumaoneka ndi maso.

Kodi Kuwala kwa Mzere Wa LED Kumapeza Bwanji Miyezo Yowala Yosiyanasiyana?

Magetsi a mizere ya LED ali ndi milingo yowala yosiyana yomwe imatha kutheka posintha kuchuluka kwa zomwe amalandira. Kuwala kwa nyali ya LED kumayesedwa mu lumens. Kuwala kochulukira komwe kuwala kwa mzere wa LED kumakhala, kumawala kwambiri.

Magetsi amtundu wa LED alinso ndi gawo lotchedwa Pulse-width modulation (PWM) lomwe limalola kuwongolera kowala. PWM ndi njira yosinthira kuchuluka kwa mphamvu zomwe zimaperekedwa ku LED poyatsa ndi kuzimitsa mwachangu. Mwakusintha mwachangu ma LED pa nthawi yake, PWM imatha kusintha kuwala kwa LED osasintha mtundu wake.

Kodi Kuwala kwa Mzere Wa LED Kufananiza Bwanji ndi Matekinoloje Ena Owunikira?

Nyali za mizere ya LED ndizosavuta kugwiritsa ntchito mphamvu ndipo zimakhala ndi moyo wautali poyerekeza ndi matekinoloje ena owunikira monga mababu a incandescent ndi nyali za fulorosenti. Magetsi amtundu wa LED amagwiritsa ntchito mphamvu zochepa chifukwa amasintha mphamvu zambiri kukhala kuwala. Izi zikutanthauza kuti amatulutsa kutentha pang'ono komanso amakhala ndi ndalama zochepa za mphamvu.

Magetsi a mizere ya LED ndi olimba kwambiri poyerekeza ndi matekinoloje ena owunikira chifukwa ali ndi mawonekedwe olimba. Siziwonongeka pang'ono ndipo sizikhudzidwa ndi kugwedezeka, zomwe zimawapangitsa kukhala abwino kugwiritsidwa ntchito pamagalimoto ndi mabwato.

Mapeto

Magetsi a mizere ya LED ndi njira zowunikira zosunthika zomwe zimapereka mphamvu, kulimba, komanso kusinthasintha. Amagwiritsa ntchito mfundo ya electroluminescence kuti apange kuwala, ndi kusakaniza mitundu kuti apange mitundu yosiyanasiyana. Kuwala kwawo kumatha kusinthidwa pogwiritsa ntchito PWM, ndipo amafananiza bwino ndi matekinoloje ena owunikira. Magetsi a mizere ya LED ndi chisankho chabwino pakuwunikira mkati, kuyatsa kokongoletsa, komanso ngakhale pazida zamagetsi.
