Yawancin injiniyoyi da ke aiki a cikinsauya wutar lantarkimasana'antusuna tsunduma a cikiLED direban wutar lantarkizane. Yawancin kamfanoni suna da manyan nau'ikan ƙirar samar da wutar lantarki guda uku:
Na farko. Gabatarwa da fasali naLED ikon direba
1. GabatarwaLED ikon direba
Ƙarfin direba na LED yana nufin ikon da aka canza zuwa hasken LED ta hanyar mai canza wuta (kamar AC-DC).
Gabaɗaya magana, shigarwar ita cemitar masana'antu mai ƙarfin lantarki ACa mafi yawan lokuta, abin da muke kira mains Electric. Lantarki na ƙasata shine 220V/50HZ, kuma Arewacin Amurka shine 120V/60HZ; na biyu, akwaihigh-voltage da low-voltage DC, irin su 12V, 24V da 36V, haka nan kuma akwai ƙananan ƙarfin wutar lantarki mai ƙarfi na AC, kamar daiwutar lantarkiza mu yi amfani da za su fitar da daidai ƙarfin lantarki.
2. Matsayi na yanzu da halayenLED direban wutar lantarki
(1)Babban abin dogaro, Gabaɗaya, garantin fitilun Arewacin Amurka na iya kaiwa shekaru 5, wanda yake da kyau.
(2)Babban inganci, Amfanisauya wutar lantarkiko mikakke wutar lantarki, da yadda ya dace na 75 ~ 80% ne quite high.
(3)Babban iko factor, gabaɗaya ya kai sama da 0.9, wanda ke nufin cewa kayan aikin ba su da aikin da ba su da amfani, suna amfani da ƙarfi sosai, kuma fitilu za su daɗe.
(4) Yana da kariya mai amfani kamar kariya mai ƙarfi, ƙarfin wuta da ƙarancin wuta.
(5) Yana da ƙura da ayyukan juriya na ruwa, kamar matakin IP44.
(6) Yana da ƙa'idodin aminci da aikin dacewa na lantarki.
(7) Za a tattauna direbobi na gama gari guda uku a ƙasa.
Na biyu. Uku gama gariLED direban wutar lantarki kayayyakin
1. Canja wurin madogarar halin yanzu
A halin yanzu, ana amfani da asauya wutar lantarkidon zayyana da'irar direban LED shine mafi yawan tsarin ƙira na yau da kullun.
Da farko, daga ra'ayin ƙira, daga ƙarshen shigarwar, gabaɗaya ta hanyarna'ura mai canzawada kanta, da high-voltage masana'antu mitar AC ikon ne tako kasa zuwa low irin ƙarfin lantarki (AC-DC), da kuma barga DC ƙarfin lantarki za a iya fitarwa ta rectifier tace kewaye. Bugu da kari, ana kara da'irar tacewa ta EMI, da'irar kariya da walƙiya, da'irar kariyar electrostatic, overvoltage da da'irar kariyar ƙarancin ƙarfi, da sauransu, kuma aikin yana da inganci kuma abin dogaro ya fi girma.
Abu na biyu, akwai da'irori guda biyu don maɓallin canzawa akai-akai na yanzu, ɗayan shine keɓewar keɓancewa ɗayan kuma shine kewayen da ba warewar ba.
Daga sunan,da warewa kewayeya sanya wasu tubalan zuwa wasu babban ƙarfin wutar lantarki zuwa sassa mara ƙarfi, tare da babban aikin aminci, babban aminci da'ira na ciki, da ɗan ƙaramin aikin rufewa na waje. Abubuwan da ake buƙata don keɓancewa na Arewacin Amurka shine <60Vac.
Wanida'ira mara warean lulluɓe shi a cikin harsashi na filastik na waje, wanda ba shi da aminci, amma farashin ya yi ƙasa da yanayin keɓewa. Dukansu hanyoyin suna da nasu amfani da rashin amfani.
Don haka daga waɗannan maki guda biyu, ana iya ganin cewa wutar lantarki mai sauyawa tana kula da mafi kyawun aikin aminci da kwanciyar hankali, wanda ya cancanci zama babban al'ada.LED direban wutar lantarkizane ra'ayin!
2. Lantarki na tuƙi mai linzami
Abin da ake kira wutar lantarki na layi, kamar yadda sunan ya nuna, wutar lantarki ce mai layi. Don zama madaidaici, ƙarfin shigarwa da fitarwa iri ɗaya ne. Misali, fitilun Arewacin Amurka suna amfani da mafita na IC madaidaiciya, tare da shigarwar 120V/60HZ da fitarwa na kusan 118V a mafi yawan lokuta.
Ana iya ganin cewa bambanci dagasauya wutar lantarkiba wai ana rage wutar lantarki ta hanyar wutan lantarki ba, amma wannanana amfani da IC guda ɗaya ko madaidaici don rarraba wutar lantarki(ICs na kowa sun haɗa da OB5656). Har ila yau, akwai ƴan abubuwan da aka gyara, akasari na aluminium, maimakon alluna masu sanye da tagulla na wutar lantarki. Wani batu kuma shi ne cewa yana da babban ƙarfin wuta da inganci, kuma baya buƙatar masu ƙarfin lantarki, waɗanda ke da tsawon rayuwa fiye dasauya wutar lantarki.
Duk da haka, komai yana da bangarori biyu. Kodayake yana da inganci, abin da yake fitarwa yana da ƙarfin lantarki. Da zarar mutum ya taɓa shi, yana da haɗari ga rayuwa, don haka gabaɗaya harsashi ne na filastik, wanda ba shi da lafiya, amma yana da wahala a wargajewa.
3. RC mataki-saukar bayani
Abin da ake kira RC ya sauka a zahiriamfani halaye na caji da fitarwa na capacitors don fitar da tuƙi na yanzudon haskaka LEDs. Yana da sauƙi don ƙira, mai sauƙin aiki, da tattalin arziki. Duk da haka, abokai masu hankali sun gano cewa yana da sauƙi a lalata da'ira saboda sauƙi, kuma akwai abubuwa da yawa marasa ƙarfi.
Musamman a lokacin rani lokacin da wutar lantarki ta iyakance, katsewar wutar lantarki da sake kunnawa akai-akai zai haifar da lalacewa ga fitilar. Fitar sa daidai yake da na IC mai layi, kuma babban ƙarfin wutar lantarki bai keɓe ba, don haka yana da haɗari sosai don amfani. Duk da haka, harsashin sa robobi ne, don haka in an kwatanta, amincinsa bai kai na wutar lantarki mai sauyawa ba.
Don haka yanayin aikace-aikacen sa na gaba ɗaya shinemai ƙarancin ƙarfifitila, kusan 5W.
Don tambayoyin samfur, da fatan za a bincikasamfurin page, ku ma barka da zuwatuntube muTa hanyar bayanin tuntuɓar da ke ƙasa, za mu ba ku amsa a cikin 24.
