Kokes ku baabbi'iyee xoogga yar, oo sababtay in caymiska sida waxaa si tartiib ah uu bedelay ilaha nuurka hore ee jira. In dukaamada qaaska ah, aad ka iibsan kartaa noocyo kala duwan oo waxyaabaha nalalka LED ku salaysan, laga bilaabo ilayska caadiga ah iyo strip LED, dhameysteen darfaha LED. oo dhan waxay leeyihiin in caadiga ah waa in ay xiriir u baahan tahay hadda ka mid ah 12 ama 24 V.

Si ka duwan ilo kale oo iftiin isticmaala element kuleylka ah waxaa laga codsadaa chip Semiconductor oo abuuraa shucaac indhaha sarkhaansan hadda ah.

Si loo fahmo wareeg ee uu Kokes 220 ka mid ah in shabakad ka, waxaad u baahan tahay si ay u bilaabaan si ay sheegayaan in uu awoodo in uu si toos ah uga shabakadda cuno ma noqon doonto. Sidaa darteed, si ay u shaqeeyaan Kokes u baahan tahay in la raaco isku xigxiga oo gaar ah oo ay ku xidhnaantooda network-danab sare.

The guryaha korontada ee uu Kokes

Sifooyinka hadda-danab ee LED - waa line qabow. Taasi waa, haddii danab ku kordhin doonaa ugu yaraan wax yar, ka dibna hadda wuxuu kordhin doonaa soo maratay, taas wuxu lahaa kulayl ee LED ah, raaceen by gubanayo ah. Si looga hor, waxaa lagama maarmaan ah in lagu daro in resistor ku soo wareegi jiray ee hadda la yareeyo.

Laakiin waxaa muhiim ah in aan la iloobin oo ku saabsan danab ugu badisay LED 20 V. In case of xiriir si network dib polarity uu is fahamka doonaa danab of 315 volts, in uu yahay 1.41 jeer ka badan hadda. Xaqiiqdu waxay tahay in network hadda ah 220 volts AC, iyo waxa ay hore u dhaco ee hal jiho, ka dibna mar kale dib.

Si looga hortago inay dhaqaaqaan hadda dhinaca ka soo horjeeda Bannaanka LED la xidhiidha waa in ay ahaadaan sida soo socota: circuit diode la soo jeestay on. Ma uusan seegi danab a dambe. In la xidhiidha waxa ay tahay in la isku midka ah.

Kale circuit LED network Beddelashada 220 waa rakibo laba Kokes ku anti-isku midka ah.

Sida for sahayda ay xoog u dhaxe la hoos resistor, ma aha ikhtiyaarka ugu fiican. Maxaa yeelay, resistor siin doonaa awood xoog leh. Tusaale ahaan, marka la isticmaalayo 24 resistor kOhm, dhereg xoogga waa qiyaastii 3 watts. Marka diode awood taxane ugu dhaco, by badh. danab dambe on diode waa in uu ahaado siman ilaa 400 V. Marka ka mid ahaa laba Kokes counter, waxaad ka dhigi kartaa laba resistor dvuhvattnyh. Ay iska caabin ah waa in ay noqdaan laba jeer sida yar. Waxaa macquul ah in mid ka mid kiiska laba kiristaalo mid ah midabo kala duwan. Sida caadiga ah, crystal hal casaan ah, cagaaran kale.

In kiiska halkaas oo resistor waa 200 ohms, joogitaanka diode ilaalinta looma baahna, tan hadda ee koorsada dambe uu yar yahay oo aan ka dhigi doono burburinta baraf. Qorshahani waa mid noqoshada ee uu Kokes ku network wuxuu leeyahay mid khasaare - iftiin nal yar. Waxaa loo adeegsan karaa, tus, waayo biiro nalalka indoor.

Sababo la xaqiiqada ah in hadda ay ku sugan dhaxe AC, waxa kuu ogolaanayaa inaad si looga fogaado kharashka loo baahnayn koronto kulaylinta hawada taasi oo ka yareysey resistor. Iyada oo hawshan qabsadaan capacitor. Ka dib oo dhan, inuu seego hadda talantaalli ah oo aan la kululeeyo.

Waxaa muhiim ah in la xasuusto in condenser ah waa inay ku aflaxaan labadaba wareegga dhaxe qeybtii, si uu u mari karin talantaalli hadda ah. Oo tan iyo LED ka qabtaan oo kaliya in hal jiho, waxaa lagama maarmaan ah in ay ku riday diode a caadiga ah (LED kale oo dheeraad ah) anti-barbar LED. Markaasuu wuxuu seegi doonaa muddo qeybtii labaad.

Marka network Beddelashada Bannaanka LED 220 la demiyo, danab ku capacitor sii joogi doonaa. Mararka qaarkood xitaa Ilodanimada inayan a full of 315 V. Waxaa halis ku shaqo joojinta hadda jirta. Si looga hor, waxaad u baahan tahay si ay u siiyaan marka lagu daro capacitor iyo dheecaan resistor ayaa qiimaha wejiga weyn, taas oo ay dhacdo jarida ka network si degdeg ah u guto capacitor ah. Iyada oo resistor this inta lagu guda jiro ay hawlgal caadi ah, socodka hadda wax yar, ha kululeeyo.

Waayo, ilaalinta pulsed amraya hadda iyo fiyuuska sida resistor iska caabin yar yahay. capacitor waa in uu caadadiisu, kaas oo loogu talagalay ah talantaalli circuit hadda la aan ka yarayn 250 V, ama 400 V.

Qorshaha la xidhiidha taxane ah nal LED ku lug rakibo of tiro ka mid ah uu Kokes ku xiran ee taxanahan. Tusaale ahaan this, kaliya hal counter diode.

Tan iyo markii ay dhibic danab ee hadda oo dhan resistor waa ka yar, ka il awoodeed waa in laga jaraa ka total dhibic danab ee guud ahaan uu Kokes ku.

loo baahan yahay si ay u dejiyaan diode la xisaabiyaa dhiganta hadda hadda ku dhex maraya uu Kokes ku, iyo danab a dambe waa loo siman yahay si wadarta walaacyada on Kokes ku. Waxaa aad u fiican in la isticmaalo xitaa tirada Kokes iyo si ay u xirmaan in antiparallel.

In mid ka mid silsilad noqon kartaa in ka badan toban Kokes. Si loo xisaabiyo capacitor ah, waa in laga jaraa ka network danab ugu sarreysa 315 xaddiga dhibic danab ee uu Kokes. Sidaas darteed, waxaan aad u ogaato tirada dhibic danab ee guud ahaan capacitor ah.

Khaladaadka Connection LED

• Khaladka ugu horeysay - tani waa marka LED ku xiran yahay oo aan joogsiga, si toos ah isha. Xaaladdan oo kale, aad u dhaqso u burburo LED, ay sabab u la'aanta ah ee gacanta ku cadadka hadda.
• Qaladka labaad - xiriir si aad ah uu Kokes ku resistor caadi qabanqaabiyaa isku midka ah.
