Marka codsiga muraayadaha LED-yada ay noqdaan kuwo aad u baahsan, xuduudaha korantada ee muraayadaha LED-yada ayaa si sii kordheysa u qiimeeya oo ka walaacsan macaamiisha. Qof kastaa wuu ogyahay in muraayadaha LED-ku ay ka kooban yihiin modules LEDs mid mid, dhabarka dambe ee shaashaddana uu ku xiran yahayKorontada LED, ka dibna xadhkaha korantada iyo xadhkaha signalada ayaa isku xidhan.
Haddaba sidee loo xisaabiyaa tirada saadka korantada ee muraayadaha LED-ka?
Qaybaha shaashadda LED-ka waxaa lagu farsameeyaa oo la soo saaraa iyadoo la isku darayo alaabta ceeriin sida laambada LED-ka, looxyada wareegga PCB, ICs, iyo xirmooyinka. Mabda'a shaqada ee modules-yada shaashadda LED-ka ayaa ah in IC-da joogtada ah ee hadda jirta ay kaxayso chip-ka-iftiinka ee kuul-laambada LED-ka si ay u muujiso midabyo.
Marka la eego midabka muuqaalka, modules-ka shaashadda LED wuxuu u qaybsan yahay saddex nooc: hal midab, laba midab, iyo midab buuxa. Marka la eego kala duwanaanta codsiga, modules LED-yada waxaa loo qaybiyaa qaybo gudaha ah iyo qaybo bannaanka ah.
Guud ahaan, hadda modules LED-ka buuxa waa weyn yahay, hadda ee hal-midab iyo laba-midab LED modules waa yar yahay, hadda ee modules LED dibadda waa weyn, iyo hadda module LED gudaha waa yara yar. Si kastaba ha noqotee, marka warshadu ay khaladeyso "dheellitirka cad" ee moduleka LED-ka, shaqada hadda jirta ee muraayadda muraayadda LED-ka ee caadiga ah ayaa guud ahaan ka hooseysa 10A.
Marka hore, waxaan u baahanahay inaan cabbirno hadda ee hal module LED.
Waxaan isticmaali karnaa multimeter si aan ugu xirno wareegga si aan u cabbirno cabbirrada dhabta ah ee moduleka LED-ka. Maanta, waxaan soo qaadan doonaa P10-4S moduleka dibadda ee LED tusaale ahaan si aan u sharaxno sida loo cabbiro cutubka hadda jira tallaabo tallaabo.
Tallaabada 1, diyaari qalabka iyo alaabta
Waxaan diyaarinaa dhowr P10-4S bannaanka bannaanka modules LED, multimeter ah (waxay cabbiri kartaa DC hadda 10A gudahood), dhowr fiilooyin, cajalad koronto, strippers silig, LED kaarka kantaroolka bandhigay, sahayda bandhig LED.
Tallaabada 2, si sax ah ugu xidh
Tijaabada cabbirkan, waxaan u isticmaalnaa multimeter-ka sida ammeter-ka DC. Qiyaasta ugu badan ee mitirka-mitirka si loo cabbiro hadda DC waa 10A. Waxaan ku xireynaa multimeter si taxane ah wareegga moduleka LED.
Taxanaha fiilooyinka gaarka ah waa:
1. Ku xidh AC 220V dhamaadka galinta korantada LED-ka (oo u dhiganta doorka transformer, u beddela 220V AC 5V DC)
2. Ku xidh siligga tirka togan ee dhamaadka wax soo saarka iyo qalinka siliga cas (tiirka togan) ee multimeterka
3. Ku xidh siliga cas godka cas ee "10A" ee ku yaala multimeterka
4. Ku xidh qalinka siliga madow siliga cas (tiirka togan) ee xadhigga korantada moduleka
5. Ku xidh xadhigga korantada moduleka si caadi ah
6. Ku xidh silig madow (cirka taban) ee xadhigga korantada moduleka dib ugu celi cirifka xun ee dhamaadka wax soo saarka tamarta LED.
Tallaabada 3, cabbir akhriska
Waxaan arki karnaa in marka godka korantada wax gelinta la xiro oo muraayadda LED-ka oo dhan la shido, hadda hal module ma ahan mid aad u weyn. Marka nuxurka dib-u-ciyaarista is-beddelo, akhrinta multimeter-ka ayaa waliba isbedbedesha, iyadoo asal ahaan lagu ilaalinayo 1-2A.
Waxaan riixnaa badhanka tijaabada ee kaadhka xakamaynta si aan u bedelno xaalada shaashadda oo aan u helno xogta tijaabada ah ee soo socota:
a. Hadda waa kan ugu weyn marka "dhammaan caddaan", qiyaastii 5.8A
b. Hadda waa 3.3A ee gobolada cas iyo cagaarka
c. Hadda waa 2.0A xaalad buluug ah
d. Marka lagu soo noqdo nuxurka barnaamijka caadiga ah, hadda waxa uu u dhexeeyaa 1-2A.
Tallaabada 4, xisaabinta
Hadda waxaan xisaabin karnaa inta qaybood ee LED-ka ee korontada LED-ku ay qaadi karto iyadoo lagu saleynayo natiijooyinka cabbirka sare. Habka xisaabinta gaarka ah waa: Koronto kasta oo LED ah ayaa asal ahaan ah transformer. Anaga oo tusaale u soo qaadanayna sahayda korantada ee 200W ee badiyaa la isticmaalo, soosaaruhu waxa uu ku siinayaa cabirka culayska sida “wax soo saarka 5V40A” iyo “heerka badalida wax ku oolka ah 88%”.
Awoodda wax ku oolka ah ee ay bixiso laydhka beddelka ee LED: P=88% x 200W=176W. Marka loo eego qaaciddada: P=UI, isticmaalka awoodda ugu badan ee hal module LED waxaa la heli karaa: P1=UI=5V x 5.8A=29W. Laga soo bilaabo tan, tirada modules ee hal koronto beddelidda LED uu qaadi karo waxaa lagu xisaabin karaa: n=P/P1=176W/29W≈6.069
Iyada oo ku saleysan xisaabinta kor ku xusan, waxaan ognahay in marka tirada modules LED qaaday uusan ka badnayn 6, sahayda LED aan la xad-dhaaf ah.
Hadda aan xisaabinay waa ugu badnaan hadda marka moduleka LED uu yahay "dhammaan cad", iyo hadda shaqeeya inta lagu jiro dib-u-ciyaarista caadiga ah inta badan waa 1 / 3-1 / 2 ee hadda ugu sarreeya. Sidaa darteed, tirada culeysyada la xisaabiyo iyadoo loo eegayo heerka ugu sarreeya ee hadda jira waa lambarka badbaadada. Markaa imisa qaybood oo LED ah ayaa la isku daray si ay u sameeyaan shaashad guud oo weyn oo LED ah, ka dibna loo qaybiyo lambarkan culeyska badbaadada leh, waxaan heli karnaa inta sahay koronto ah oo loo isticmaalo shaashadda LED-ka.
