Waa in-arag: Aqoonta Aqoonta Awooda Darawalka LED

Kuleyl darida, awoodda wadista, iyo ilaha iftiinka ayaa ah qaybaha ugu muhiimsan ee alaabta iftiinka LED ee wanaagsan. Inkasta oo kuleylka kuleylka uu si gaar ah muhiim u yahay, saameynta kuleylka kuleylka waxay si toos ah u saameyneysaa tayada nolosha ee alaabta iftiinka, laakiin isha iftiinka ayaa ah qaybta ugu muhiimsan ee alaabta oo dhan. Xasiloonida nolosha iyo wax soo saarka hadda iyo tamarta korontada lafteeda ayaa saameyn weyn ku leh tayada nolosha guud ee alaabta. Korontada darawalka LED sidoo kale waa badeecad taageeraya. Waqtigan xaadirka ah, tayada korontada ee suuqa ayaa ah mid aan sinnayn. Kuwa soo socdaa waxay bixiyaan aqoonta la xidhiidha awoodda darawalka LED. 1. Waa maxay koronto-dhaliyaha LED-ka ee LED-ku wuxuu u beddelaa sahayda koronto gaar ah si uu u kaxeeyo beddelaha iftiinka LED-ka. Caadi ahaan: gelinta awoodda wadista LED-ka waxaa ka mid ah soo noqnoqoshada koronto-sare ee AC (taas oo ah, awoodda magaalada), korantada hoose DC DC , High-voltage DC, hoose-voltage iyo sare-frequency AC (sida soo-saarka transformers elegtroonig ah), iwm. Wax soo saarka korantada wadista LED-ka ayaa inta badan ah isha joogtada ah ee hadda jirta taas oo bedeli karta danabka isbeddelka hoos u dhaca qiimaha koronta hore ee LED. Qaybaha udub-dhexaadka ah ee sahayda LED-ka waxaa ka mid ah kontaroolaha beddelka, soo-gelinta, qaybta beddelka (MOSFET), iska caabbinta jawaab-celinta, aaladda shaandhaynta gelinta, shaandhada soo-saarka, iwm. Marka loo eego shuruudaha munaasabadaha kala duwan, waa inay jiraan wareegyada ilaalinta xad-dhaafka ah ee soo-gelinta, wareegyada ilaalinta cadaadiska la'aanta, ilaalinta waddada furitaanka LED, ilaalinta xad-dhaafka ah iyo wareegyada kale. 2. Astaamaha sahayda koronto wadida LED-ka (1) Kalsoonida sare waxay gaar ahaan la mid tahay awooda darawalka ee nalalka wadooyinka LED, kaas oo lagu rakibay joog sare, kuma habboona dayactirka, qiimaha dayactirka sidoo kale waa weyn yahay. (2) Waxtarka sare ee LED waa badeecad tamar-badbaadinaysa, hufnaanta awoodda wadista waa sarraysaa. Aad bay muhiim ugu tahay kuleylka kuleylka ee korontada ku jirta nalka. Waxtarka tamarta korontada ayaa aad u sareysa, luminta miisaankeedu waa yar yahay, kulaylka laambada ayaa noqon doona mid yar, taas oo hoos u dhigi doonta kor u kaca heerkulka laambada. Waxay faa'iido u leedahay dib u dhigista cilladda iftiinka LED. (3) Qodobbada awoodda sare leh iyo qodobbada awoodda ayaa ah shuruudaha culeyska xajinta. Guud ahaan, qalabka korantada ee ka hooseeya 70 watts, ma jiraan tilmaameyaal qasab ah. Inkasta oo hal arrimood oo quwad ah oo awood yar leh, qodobbada tamarta hooseeya ay saameyn yar ku leeyihiin korantada korantada, isticmaalka nalalka habeenkii, nooca isku midka ah ayaa aad u badan, waxay keeni doontaa wasakh aad u daran shabakada korontada. Awoodda darawalka LED ee 30 watts 40 watts, waxaa la sheegay in mustaqbalka dhow, ay jiri karaan tilmaamo gaar ah oo ku saabsan arrimaha korontada. (4) Waxaa jira laba nooc oo hababka wadista hadda: mid waa il koronto joogto ah ilo durdurro badan oo joogto ah, iyo il kasta oo joogto ah oo joogto ah sahayda LED kasta si gaar ah. Sidan oo kale, isku-dhafka ayaa ah mid dabacsan, cilladda LED-ka oo dhan, ma saameynayso shaqada LED-yada kale, laakiin qiimaha ayaa noqon doona mid wax yar ka sarreeya. Midda kale waa koronto joogto ah oo joogto ah, taas oo sidoo kale ah “Zhongke Huibao “Habka wadista ee la qaatay, LED wuxuu ku xiran yahay ama barbar socda. Faa'iidada ay leedahay ayaa ah in qiimaha uu hooseeyo, laakiin dabacsanaantu waa mid liidata, waxaana lagama maarmaan ah in la xalliyo dhibaatada cillad LED-ga gaar ah, taas oo aan saameyn ku yeelanayn hawlaha kale ee LED-yada. Labadan qaab waxay wada nool yihiin in muddo ah. Hababka wax-soo-saarka korontada ee Multi-Lu Hengliu ayaa ka fiicnaan doona marka la eego qiimaha iyo waxqabadka. Waxaa laga yaabaa inay tahay jihada guud ee mustaqbalka. (5) Awoodda lagu ilaalinayo ilaalinta LED-yada LED-yada waa mid liidata, gaar ahaan awoodda korantada ee ka-hortagga. Xoojinta ilaalinta aaggan sidoo kale waa muhiim. Nalalka LED-yada qaarkood ayaa lagu rakibay bannaanka, sida nalalka waddooyinka. Sababo la xiriira furitaanka rarka korantada iyo kicinta hillaaca, nidaamka grid wuxuu ku duuli doonaa mowjado kala duwan, mowjadaha qaarkoodna waxay sababi doonaan waxyeellada LED-ka. Markaas ah “Zhongke Huibao “Awoodda darawalku waa inay ka maqan tahay ilaalinta hirarka kor u kaca. Sida beddelka joogtada ah ee korontada iyo laambada, sahayda korantada wadista LED-ka waa inay lahaataa awood ay ku xakamayso kor u kaca oo ay ilaaliso awoodda LED-ka ee aan waxyeello u geysan. (6) Marka lagu daro shaqada ilaalinta caadiga ah, awoodda shaqada ilaalinta ayaa ugu fiican in lagu daro heerkulka LED-ga ee jawaab-celinta xun ee soo-saarka joogtada ah ee hadda jirta si looga hortago heerkulka LED-ka inuu aad u sarreeyo ;. 3. Kala-soocidda iyadoo loo eegayo habka wadista (1) Wax-soo-saarka hadda jira ee wareegga wadista joogtada ah ee joogtada ah ee joogtada ah waa mid joogto ah, halka wax-soo-saarka DC-gu uu isbeddelayo qiyaas gaar ah oo leh cabbirka caabbinta culeyska, qiimaha caabbinta culeysku waa yar yahay, wax-soo-saarka danabku waa Haddii uu hooseeyo, way sii weynaataa qiimaha caabbinta culeyska, kororka wax soo saarka ayaa sarreeya; wareegga joogtada ah ee joogtada ahi kama cabsanayo culeyska wareegga gaaban, laakiin culeyska si adag ayaa loo mamnuucay; wareegga wadista ee Hengliu ayaa aad ugu habboon, laakiin qiimuhu aad buu u sarreeyaa; u fiirso; fiiro gaar ah u leh dulqaadka ugu badan iyo qiimaha korantada ee la isticmaalo, waxay xaddidaysaa tirada LED-yada. (2) Ka dib marka la go'aamiyo xuduudaha kala duwan ee wareegga xasilinta, tamarta wax soo saarka ayaa go'an, iyo wax soo saarka hadda isbeddelaya kororka iyo hoos u dhaca culeyska; Wareeg gaaban; U wado LED-ka si uu u wado wareegga korantada-driven, xadhig kasta wuxuu u baahan yahay inuu ku daro iska caabin ku habboon si uu u sameeyo xadhig kasta oo LED ah oo muujinaya dhalaalka celceliska; dhalaalka waxaa saameyn doona isbedelka danab ee hagaajinta. 4. Faa'iidooyinka iyo khasaaraha guud ee joogtada ah ee hadda jira iyo habka loo raaco dariiqa ayaa la barbar dhigayaa guud ahaan joogtada ah ee hadda jira. Inkasta oo ay jiraan khasaare badan iyo kharashyo badan, kharashku waa mid aad u sarreeya. Laakiin waxay si dhab ah u ilaalin kartaa nolosha LED-ka waxayna kordhin kartaa LED-ka, markaa socodka joogtada ah ee wadada waa isbeddelka mustaqbalka. 5. La'aanta koronto la'aanta LED-ku-gudbinta korontadu hadda kuma filna: 1. Farsamayaqaannada shirkadaha soo saara nalalka LED-ka iyo alaabada la xidhiidha ma yaqaaniin wax ku filan oo ku saabsan sahayda beddelka. Oo ma aha in la tixgeliyo waafaqid ku filan electromagnetic, weli waxaa jira qaar ka mid ah khataraha qarsoon; 2. Inta badan soosaarayaasha korantada LED-ka waxay ka beddelaan sahayda tamarta beddelka ah ee caadiga ah si ay u sameeyaan koronto LED. Tilmaamaha iyo fahamka LED kuma filna; Waxaa jira ku dhawaad ​​ma jiraan halbeegyo, kuwaas oo intooda badan ah heerka tixraaca sahayda korantada iyo toosiyaha elektarooniga ah; Inta badan sahayda korantada LED-ku maaha mid la mid ah, markaa inta badan qaddarku waa yar yahay. Haddii mugga iibsigu yar yahay, qiimuhu waa sarreeyaa, alaab-qeybiyaha qaybta ma aha mid aad u wada-shaqeyn ah; 4. Xasiloonida korantada LED-ka: gelinta korantada ballaaran, heerkulka sare iyo shaqada heerkulka hooseeya, heerkulka ka sarreeya, ilaalinta korantada iyo arrimaha kale ayaan mid mid u xallin. Marka hore waa nolosha guud ee wareegga wadista, gaar ahaan qalabka muhiimka ah sida: nolosha capacitors ee heerkulka sare wuxuu si toos ah u saameeyaa nolosha tamarta korontada; in LED-ku uu ka hor yimaado waxtarka beddelka sare, gaar ahaan marka uu wado LED-yada awoodda sare leh, sababtoo ah waxaa wada LED-yada awoodda sare leh, sababtoo ah waxaa kaxeeya LED-koronto sare, sababtoo ah darawalka awoodda sare ee LED waa sababtoo ah LED-ka awoodda sare ee darawalka, sababtoo ah waa awoodda sare ee darawalka, sababtoo ah waa LED-ga awoodda sare ee darawalka, sababtoo ah waa LED-ga awoodda sare ee darawalka, sababtoo ah waa awoodda sare ee darawalka. LED, sababtoo ah waa LED-ga awoodda sare ee darawalka, sababtoo ah waa LED-ga awoodda sare ee darawalka, sababtoo ah waa LED-ga awoodda sare ee darawalka, sababtoo ah waa LED-ga awoodda sare ee darawalka, sababtoo ah waa LED. sababtoo ah LED-ga awoodda sare ee darawalku waa sababtoo ah xitaa waa run, sababtoo ah xitaa way ka sii badan tahay. Dhammaan tamarta aan iftiinka lahayn waxaa loo isticmaalaa sida kuleylka kuleylka, iyo waxtarka beddelka awoodda ayaa aad u hooseeya, taas oo saameynaysa waxqabadka tamarta LED-saamaynta. Waqtigan xaadirka ah, codsiyada leh awood yar (1-5W), saamiga qiimaha Hengliu ee sahayda korantada wadista waxay ku dhowdahay 1/3, taas oo ku dhow qiimaha ilaha iftiinka, taas oo saameynaysa horumarinta suuqa ilaa xad. .
