Bayan shekaru na ci gaba, na al'ada na kowa anode LED ya kafa barga masana'antu sarkar, tuki da shahararsa na LED nuni. Duk da haka, yana kuma da rashin lahani na girman allo da yawan amfani da wutar lantarki. Bayan bayyanar fasahar samar da 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 ta LED na gama gari? Menene amfanin wannan fasaha?
1. Menene LED cathode na kowa?
"Cathode na kowa" yana nufin hanyar samar da wutar lantarki ta cathode na kowa, wanda shine ainihin fasahar ceton makamashi don nunin nunin LED. Yana nufin amfani da hanyar cathode na gama gari don kunna allon nunin LED, wato R, G, B (ja, kore, shuɗi) na beads ɗin fitilar LED ana sarrafa su daban, kuma na yanzu da ƙarfin lantarki an ware su daidai ga R. , G, B fitilu beads bi da bi, saboda mafi kyau duka aiki ƙarfin lantarki da halin yanzu da ake bukata ta R, G, B (ja, kore, blue) fitila beads ne daban-daban. Ta wannan hanyar, na farko na yanzu yana wucewa ta cikin beads na fitilu sannan zuwa ga mummunan lantarki na IC, za a rage raguwar ƙarfin wutar lantarki na gaba, kuma juriya na ciki zai zama karami.
2. Menene bambanci tsakanin na kowa cathode da na kowa anode LEDs?
①. Daban-daban hanyoyin samar da wutar lantarki:
Hanyar samar da wutar lantarki ta cathode na yau da kullun shine cewa na yanzu na farko yana wucewa ta cikin bead ɗin fitila sannan zuwa ga mummunan sandar IC, wanda ke rage raguwar ƙarfin lantarki na gaba da juriya na ciki.
Babban anode shine cewa halin yanzu yana gudana daga allon PCB zuwa fitilar fitila, kuma yana ba da wutar lantarki ga R, G, B (ja, kore, shuɗi) daidai gwargwado, wanda ke haifar da raguwar ƙarfin wutar lantarki mai girma a cikin kewaye.
②. Wutar lantarki daban-daban:
Common cathode, shi zai samar da halin yanzu da ƙarfin lantarki zuwa R, G, B (ja, kore, blue) dabam. Bukatun ƙarfin lantarki na ja, kore da shuɗi na fitilar fitila sun bambanta. Bukatar ƙarfin lantarki na beads ɗin fitilar ja shine kusan 2.8V, kuma buƙatun ƙarfin lantarki na beads ɗin fitila mai shuɗi-kore shine kusan 3.8V. Irin wannan samar da wutar lantarki na iya samun ingantaccen wutar lantarki da ƙarancin wutar lantarki, kuma zafin da LED ke haifarwa yayin aiki yana da ƙasa da ƙasa.
Common anode, a daya bangaren, yana ba R, G, B (ja, kore, blue) wani ƙarfin lantarki sama da 3.8V (kamar 5V) domin hadaddun wutar lantarki. A wannan lokacin, ƙarfin lantarki da aka samu ta ja, kore da shuɗi shine haɗin kai 5V, amma mafi kyawun ƙarfin ƙarfin aiki da beads ɗin fitilu uku ke buƙata ya fi 5V. Bisa ga tsarin wutar lantarki P=UI, lokacin da halin yanzu ya kasance baya canzawa, mafi girman ƙarfin wutar lantarki, mafi girma da wutar lantarki, wato, mafi girma yawan amfani da wutar lantarki. A lokaci guda, LED kuma zai samar da ƙarin zafi yayin aiki.
TheAllon Talla na LED na Waje na Duniya na Uku wanda XYGLED ya Haɓaka, yana ɗaukar cathode gama gari. Idan aka kwatanta da na al'ada 5V ja, kore, da shuɗi mai haske-emitting diodes, ingantacciyar sandar guntu jajayen LED shine 3.2V, yayin da kore da shuɗi LEDs sune 4.2V, rage yawan amfani da wutar lantarki da aƙalla 30% da kuma nuna kyakkyawan makamashi- aikin ceto da rage yawan amfani.
3. Me yasa na kowa cathode LED nuni yana haifar da ƙananan zafi?
Yanayin samar da wutar lantarki na musamman na cathode na allon sanyi yana sa nunin LED ya haifar da ƙarancin zafi da ƙananan zafin jiki yayin aiki. A karkashin al'ada yanayi, a cikin farin ma'auni jihar da kuma lokacin kunna bidiyo, da zazzabi na sanyi allo ne game da 20 ℃ kasa da na al'ada waje LED nuni na wannan model. Don samfuran ƙayyadaddun ƙayyadaddun bayanai kuma a daidai wannan haske, zafin allo na nunin LED na cathode na yau da kullun ya fi digiri 20 ƙasa da na samfuran nunin LED na anode na yau da kullun, kuma yawan wutar lantarki ya fi 50% ƙasa da wancan. na al'ada na kowa anode LED nuni kayayyakin.
Matsakaicin zafin jiki da kuma amfani da wutar lantarki na nunin LED koyaushe sune mahimman abubuwan da suka shafi rayuwar sabis na samfuran nunin LED, kuma "nuni na LED na cathode na yau da kullun" na iya magance waɗannan matsalolin biyu da kyau.
4. Mene ne abũbuwan amfãni daga cikin na kowa cathode LED nuni?
①. Madaidaicin samar da wutar lantarki yana adana makamashi da gaske:
Samfurin cathode na yau da kullun yana ɗaukar madaidaicin fasahar sarrafa wutar lantarki, dangane da halaye daban-daban na hotoelectric na manyan launuka uku na LED ja, kore da shuɗi, kuma an sanye shi da tsarin kula da nuni na IC mai hankali da ƙirar mai zaman kanta mai zaman kanta don daidai rarraba ƙarfin lantarki daban-daban. zuwa LED da da'irar tuƙi, ta yadda ƙarfin samfurin ya kai kusan 40% ƙasa da na samfuran makamancin haka a kasuwa!
②. Ajiye makamashi na gaskiya yana kawo launuka na gaskiya:
Hanyar tuƙi na LED na cathode na kowa na iya sarrafa wutar lantarki daidai, wanda ke rage yawan wutar lantarki da haɓakar zafi. Tsawon tsayin LED ba ya motsawa a ƙarƙashin ci gaba da aiki, kuma ana nuna launi na gaskiya!
③. Ajiye makamashi na gaskiya yana kawo tsawon rai:
An rage yawan amfani da makamashi, ta haka yana rage yawan zafin jiki na tsarin, da kyau rage yiwuwar lalacewar LED, inganta kwanciyar hankali da amincin dukan tsarin nuni, da kuma fadada tsarin rayuwa.
5. Menene ci gaban fasahar cathode na kowa?
Kayayyakin tallafi masu alaƙa da fasahar nuni na LED na cathode na kowa, kamar LED, samar da wutar lantarki, direban IC, da sauransu, ba su da girma kamar sarkar masana'antar anode LED gama gari. Bugu da kari, na kowa cathode IC jerin ba a kammala a halin yanzu, kuma gaba ɗaya girma ba girma, yayin da na kowa anode har yanzu ya mamaye 80% na kasuwa.
Babban dalilin jinkirin ci gaba na fasahar cathode na kowa 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, PCB, da sauransu, wanda ke da tsada.
A cikin wannan zamanin na babban kira don ceton makamashi, fitowar na kowa cathode m LED nuni fuska ya zama goyon bayan batu da wannan masana'antu. Duk da haka, har yanzu akwai sauran hanyar da za a bi don cimma cikakkiyar ci gaba da aikace-aikace a cikin ma'ana mafi girma, wanda ke buƙatar haɗin gwiwar haɗin gwiwa na dukan masana'antu. A matsayin yanayin ci gaba na ceton makamashi, allon nuni na LED na cathode na kowa ya ƙunshi amfani da farashin aiki na wutar lantarki. Sabili da haka, ceton makamashi yana da alaƙa da bukatun masu sarrafa allon nuni na LED da kuma amfani da makamashi na ƙasa.
Daga halin da ake ciki yanzu, na kowa cathode LED makamashi-ceton nuni allo ba zai ƙara kudin da yawa idan aka kwatanta da na al'ada nuni allo, kuma zai ceci halin kaka a baya amfani, wanda aka sosai mutunta da kasuwa.
