Korontada darawalka LED-ka waa beddele koronto oo korontada u beddela danab iyo koronto gaar ah si uu LED-ka u soo saaro iftiin. Xaaladaha caadiga ah: gelinta awoodda darawalka LED-ka waxaa ka mid ah AC-ga soo noqnoqda ee korontada ku shaqeeya (tusaale ahaan awoodda magaalada), DC-ga soo dhaca ee hooseeya, DC-ga soo dhaca ee sare, danab hoose iyo danab sare. AC-ga soo baxa ee soo baxa (sida wax soo saarka qalabka elektarooniga ah), iwm.

–Sida waafaqsan habka wadista:

(1) Nooca hadda socda ee joogtada ah

a. Haddalka wax soo saarka ee wareegga wadista hadda ee joogtada ah waa mid joogto ah, laakiin danabka DC ee soo baxaya wuu ku kala duwan yahay heer gaar ah iyadoo la eegayo cabbirka iska caabbinta culayska. Inta uu yar yahay iska caabbinta culayska, ayuu yar yahay danabka wax soo saarka. Inta uu weyn yahay iska caabbinta culayska, ayuu soo baxayaa danabka ayaa sarreeya;

b. Wareegga joogtada ah ee hadda jira kama baqayo wareegga gaaban ee culayska, laakiin si adag ayaa loo mamnuucay in culayska si buuxda loo furo.

c. Waa ku habboon tahay wareegga wadista ee joogtada ah si uu u wado LED-yada, laakiin qiimuhu waa mid aad u sarreeya.

d. Fiiro gaar ah u yeelo qiimaha ugu badan ee korontada iyo danabka ee la isticmaalo, kaas oo xaddidaya tirada LED-yada la isticmaalo;

(2) Nooca la nidaamiyay:

a. Marka la go'aamiyo xuduudaha kala duwan ee wareegga nidaamiyaha danabka, danabka soo-saarku waa go'an yahay, laakiin hadda soo-saarku wuu isbeddelaa marka culaysku kordho ama hoos u dhaco;

b. Wareegga nidaamiyaha danabka kama baqayo furitaanka culayska, laakiin si adag ayaa loo mamnuucay in gebi ahaanba la gaabiyo culayska.

c. LED-ka waxaa ku shaqeeya wareeg wadista oo xasiliya danabka, xarig kastana waa in lagu daraa iska caabin ku habboon si xarig kasta oo LED-yadu u muujiyaan dhalaal celcelis ahaan;

d. Iftiinka waxaa saameyn doona isbeddelka danabka ee ka yimaada hagaajinta.

– Kala-soocidda awoodda wadista LED-ka:

(3) Wadista garaaca wadnaha

Codsiyada LED-ka badankood waxay u baahan yihiin shaqooyin yareyn, sidaNalalka gadaal ee LED-kaama nalalka dhismaha oo yaraada. Shaqada nalalka waxaa lagu xaqiijin karaa iyadoo la hagaajinayo iftiinka iyo isbarbardhigga LED-ka. Si fudud loo yareeyo qulqulka qalabka ayaa laga yaabaa inay awood u yeelato inay hagaajiso.Nalalka LED-kaqiiqa, laakiin u oggolaanshaha LED-ka inuu shaqeeyo xaalad ka hooseysa kan la qiimeeyay waxay sababi doontaa cawaaqib xumo badan oo aan loo baahnayn, sida hoos u dhaca chromatic. Beddelka hagaajinta hadda ee fudud waa in lagu daro koontaroolaha isbeddelka ballaca garaaca (PWM) darawalka LED-ka. Calaamadda PWM si toos ah looguma isticmaalo in lagu xakameeyo LED-ka, laakiin waa in lagu xakameeyo badhanka, sida MOSFET, si loo siiyo hadda loo baahan yahay LED-ka. Xakameeyaha PWM badanaa wuxuu ku shaqeeyaa soo noqnoqosho go'an wuxuuna hagaajiyaa ballaca garaaca si uu ula mid noqdo wareegga shaqada ee loo baahan yahay. Chips-ka LED-ka ee hadda jira badankood waxay isticmaalaan PWM si ay u xakameeyaan qiiqa iftiinka LED-ka. Si loo hubiyo in dadku aysan dareemin dhalaal muuqda, soo noqnoqoshada garaaca PWM waa inay ka weyn tahay 100HZ. Faa'iidada ugu weyn ee xakamaynta PWM waa in hadda la dhimo iyada oo loo marayo PWM ay sax tahay, taas oo yaraynaysa farqiga midabka marka LED-ku uu iftiimiyo.

(4) Qalabka AC-ga

Sida laga soo xigtay codsiyo kala duwan, darawallada AC waxaa sidoo kale loo qaybin karaa saddex nooc: buck, boost, iyo converter. Farqiga u dhexeeya darawalka AC iyo darawalka DC, marka lagu daro baahida loo qabo in la saxo oo la sifeeyo AC-ga la geliyo, waxaa sidoo kale jira dhibaato go'doon iyo go'doon la'aan ah marka laga eego dhinaca badbaadada.

Darawalka gelinta AC-ga waxaa inta badan loo isticmaalaa laambadaha dib-u-hagaajinta: toban laambadood oo PAR ah (Parabolic Aluminium Reflector, laambad caadi ah oo ku taal masrax xirfadeed), nalalka caadiga ah, iwm., waxay ku shaqeeyaan 100V, 120V ama 230V AC. Laambadda MR16, waxay u baahan tahay inay ka shaqeyso gelinta 12V AC. Sababtoo ah dhibaatooyin adag, sida awoodda yareynta ee triac-ka caadiga ah ama kuwa geeska hoggaaminaya iyo kuwa geeska gadaal ka riixaya, iyo iswaafajinta transformers-ka elektaroonigga ah (laga bilaabo danabka khadka AC si loo soo saaro 12V AC hawlgalka laambadda MR16) Dhibaatada waxqabadka (taasi waa, hawlgalka aan dhalaalayn), sidaas darteed, marka la barbar dhigo darawalka gelinta DC, goobta ku lug leh darawalka gelinta AC waa mid aad u adag.

Korontada AC-ga (wadiyaha ugu weyn) waxaa lagu dabaqaa darawalka LED-ka, guud ahaan iyada oo loo marayo tallaabooyin sida hoos u dhigista, hagaajinta, shaandhaynta, xasilinta danabka (ama xasilinta hadda), iwm., si loogu beddelo korontada AC-ga koronto DC, ka dibna la siiyo LED-yo ku habboon iyada oo loo marayo wareegga wadista ee ku habboon. Korontada shaqaynaysa waa inay lahaataa hufnaan beddel sare, cabbir yar iyo kharash yar, isla markaana xallisa dhibaatada go'doominta badbaadada. Iyadoo la tixgelinayo saameynta shabakadda korontada, faragelinta elektaroonigga ah iyo arrimaha arrimaha korontada waa in sidoo kale la xalliyaa. LED-yada awoodda hoose iyo kuwa dhexe, qaab-dhismeedka wareegga ugu fiican waa wareegga beddelaha duulista ee hal-dhammaad leh oo go'doonsan; codsiyada awoodda sare leh, waa in la isticmaalaa wareegga beddelaha buundada.

–Qaybinta goobta rakibaadda korontada:

Awoodda wadista waxaa loo qaybin karaa koronto dibadda ah iyo koronto ku dhex jirta iyadoo loo eegayo booska rakibidda.

(1) Korontada dibadda

Sida magacu tilmaamayo, korontada dibadda waa in lagu rakibaa korontada dibadda. Guud ahaan, danabku waa mid aad u sarreeya, taas oo khatar ku ah badbaadada dadka, waxaana loo baahan yahay koronto dibadda ah. Farqiga u dhexeeya korontada gudaha ku jirta ayaa ah in korontada ay leedahay qolof, nalalka waddooyinkana ay yihiin kuwo caadi ah.

(2) Koronto ku dhex jirta

Korontada waxaa lagu rakibay laambadda. Guud ahaan, danabku waa mid hooseeya, laga bilaabo 12v ilaa 24v, taas oo aan khatar ammaan u geysanayn dadka. Kan caadiga ah wuxuu leeyahay nalalka nalalka.
