Bayan shekaru na ci gaba, al'ada na kowa anode LED nuni ya kafa barga masana'antu sarkar, wanda ya haifar da popularization na LED nuni.Duk da haka, yana kuma da kurakurai, matsanancin zafin jiki da yawan amfani da wutar lantarki.Bayan bayyanar fasahar nuna wutar lantarki ta LED na kowa, ya jawo hankali sosai a kasuwar nunin LED.Wannan hanyar samar da wutar lantarki na iya cimma matsakaicin tanadin makamashi na 75%, don haka menene fasahar samar da wutar lantarki na nunin LED na cathode na kowa?Menene amfanin wannan fasaha?
Menene fa'idodin fasahar samar da wutar lantarki na nunin LED cathode na yau da kullun
1. Mene ne na al'ada cathode LED nuni?
"Cathode na kowa" yana nufin hanyar samar da wutar lantarki ta cathode gama gari.A zahiri, wannan fasaha ce ta ceton makamashi don nunin LED.Yana nufin amfani da cathode gama gari don kunna nunin LED.B (ja, kore, blue) yana raba wutar lantarki, kuma yana rarraba daidaitattun wutar lantarki na R, G, B fitilu beads, saboda R, G, B (ja, kore, blue) fitilu suna buƙatar aiki mafi kyau. ƙarfin lantarki, kuma na yanzu ya bambanta, Saboda haka, na yanzu zai fara wucewa ta cikin bead ɗin fitila, sa'an nan kuma ya kai ga mummunan sandar IC, yana rage raguwar ƙarfin wutar lantarki na gaba da rage juriya na ciki.
2. Menene bambanci tsakanin na kowa cathode da na kowa anode LED nuni?
①.Daban-daban hanyoyin samar da wutar lantarki:
Hanyar samar da wutar lantarki ta cathode da aka saba amfani da ita ita ce, na farko na yanzu ya wuce ta cikin fitilun fitila sannan ya kai ga mummunan sandar da'irar da aka haɗa, ta yadda raguwar wutar lantarki ta gaba ta zama ƙarami kuma mai juriya ya zama ƙarami.
Babban anode shine halin yanzu yana gudana daga allon PCB zuwa beads fitilu, kuma a ko'ina yana ba da wutar lantarki zuwa R, G, B (ja, kore, shuɗi), ta yadda ƙarfin wutar lantarki na gaba na kewaye ya zama mafi girma.
②.Wutar wutar lantarki ya bambanta:
Na kowa cathode, wadata halin yanzu da ƙarfin lantarki don R, G, B (ja, kore, blue), bi da bi.LEDs ja, kore da shuɗi suna da buƙatun ƙarfin lantarki daban-daban.Wutar lantarki na beads na fitilar ja yana da kusan 2.8V, kuma ƙarfin wutar lantarki na shuɗi da koren fitilar ya kai kusan 3.8V, wannan wutar lantarki na iya samun daidaitaccen wutar lantarki da samar da wutar lantarki.Saboda ƙananan hasara, zafin da LED ya haifar yayin aiki yana da ƙasa da yawa.
Cathode na gama gari yana buƙatar ba R, G, B (ja, kore, shuɗi) haɗin wutar lantarki wanda ya fi 3.8V (kamar 5V).A wannan lokacin, ƙarfin lantarki da aka samu ta ja, kore da shuɗi shine uniform 5V, yayin da ja, kore, Mafi kyawun ƙarfin ƙarfin aiki da buƙatun fitilar shuɗi uku ke buƙata ya fi 5V.Bisa ga tsarin wutar lantarki P = UI, a ƙarƙashin yanayi na yau da kullum, mafi girman ƙarfin wutar lantarki, mafi girma da wutar lantarki, wato, mafi girma yawan amfani da wutar lantarki, yayin da nunin LED ke aiki Ana samun ƙarin zafi a cikin tsari.
3. Me ya sa zafi na talakawa cathode LED nuni m?
Yanayin samar da wutar lantarki na musamman na cathode na allo mai sanyi yana sa tsarin nunin LED ya haifar da ƙarancin zafi da ƙananan zafin jiki.A ƙarƙashin yanayi na al'ada, yayin farin ma'auni da sake kunna bidiyo, zazzabi na allon sanyi yana da kusan 20 ° C ƙasa da na al'ada na LED na waje na nuni iri ɗaya.A karkashin guda bayani dalla-dalla da wannan haske, allon zafin jiki na talakawa cathode LED nuni ne fiye da 20 digiri kasa da na talakawa anode LED nuni kayayyakin, da kuma ikon amfani ne 50% m fiye da na talakawa anode LED nuni kayayyakin.
Babban zafin jiki na allon nunin LED da yawan amfani da wutar lantarki koyaushe sune mahimman abubuwan da suka shafi rayuwar sabis na allon nunin LED."Common cathode LED nuni" na iya magance waɗannan matsalolin guda biyu.
4. Menene amfanin talakawa cathode LED nuni?
e ikon samar da gaske yana adana makamashi:
Kayayyakin cathode na yau da kullun suna ɗaukar ingantattun fasahar sarrafa wutar lantarki, gwargwadon halaye daban-daban na optoelectronic na manyan launuka uku na LED ja, kore da shuɗi, haɗe tare da tsarin kula da nuni na IC mai hankali da yanayin sadaukarwa mai zaman kanta, nau'ikan wutar lantarki na LED da kewayen tuki daidai suke. kasaftawa, ta yadda yawan wutar lantarkin samfurin ya yi yawa.Irin waɗannan samfuran a kasuwa suna adana kusan 40%!
②.Ajiye makamashi na gaske yana kawo launi na gaske:
Hanyar tuƙi na cathode LED da aka saba amfani da shi na iya sarrafa wutar lantarki daidai, yayin da rage yawan wutar lantarki da samar da zafi, tsayin daka na LED ba zai yi nisa ba yayin ci gaba da aiki, kuma ana iya nuna launi na gaskiya a tsaye!
③.Ainihin ceton makamashi yana kawo tsawon rai:
An rage yawan amfani da makamashi, yawan zafin jiki na tsarin yana raguwa sosai, yiwuwar lalacewar LED ya ragu sosai, an inganta kwanciyar hankali da amincin duk tsarin nuni, kuma an kara tsawon rayuwar sabis na tsarin.
5. Menene abubuwan da ke faruwa a cikin fasaha mara kyau na gama gari?
Dangane da fasahar nunin LED na cathode na gama gari kamar LEDs, samar da wutar lantarki, da direban ICs, bai kai girma kamar sarkar masana'antar Ram LED ba.Bugu da ƙari, jerin na yau da kullum na cathode IC bai cika ba, kuma yawan tallace-tallace na gaba ɗaya ba shi da girma.Har yanzu Ram yana mamaye kashi 80% na kasuwa.
Babban dalilin jinkirin haɓaka fasahar cathode na yau da kullun a halin yanzu shine babban farashin samarwa.Dangane da haɗin gwiwar sarkar samar da kayayyaki na asali, cathode na gama gari yana buƙatar haɗin kai na musamman a kowane ƙarshen sarkar masana'antu kamar kwakwalwan kwamfuta, marufi, da PCBs, kuma farashin yana da yawa.
A cikin wannan zamanin na musamman high bukatar makamashi ceto, da fitowan na kowa m m m LED nuni ya zama goyon baya batu na wannan masana'antu ta bi.Duk da haka, har yanzu akwai sauran hanyar da za a bi don cimma cikakkiyar haɓakawa da aikace-aikace a cikin ma'ana mafi girma, kuma ana buƙatar ƙoƙarin haɗin gwiwa na dukan masana'antu.Nunin LED na cathode na yau da kullun ya haɗa da amfani da wutar lantarki da farashin aiki, wanda shine haɓakar haɓakar kuzarin ceton makamashi.Don haka, tanadin makamashi da rage yawan amfani yana da alaƙa da buƙatun masu aikin nunin LED da kuma amfani da makamashin ƙasa.
Yin la'akari da halin da ake ciki a halin yanzu, nunin ceton makamashi na cathode LED na yau da kullum ba zai kara yawan farashi ba idan aka kwatanta da nuni na gargajiya, kuma zai adana farashi a amfani da shi a nan gaba, wanda kasuwa ya karɓa sosai.
