Isticmaalka diodes leh LEDs
Polarity ee wareegyada LED
Markaad bilowdo adigoo isticmaalaya diodes wareeggaaga LED-ka, waxaad u baahan tahay inaad fiiro gaar ah u yeelato polarity. Diodes waxay u ogolaadaan korontadu inay u dhaqaaqdo hal jiho. Haddi aad ku xidho diode iftiin bixisa hab khaldan, ma shidi doono. Xitaa waad dhaawaci kartaa
Diodes waxay u oggolaadaan socodka korantada inuu u gudbo hal jiho, oo loo yaqaan jihada hore.
Waxay xannibaan hadda jihada ka soo horjeeda, taas oo ah jihada gadaale.
Dabeecaddan aan jiho lahayn ayaa muhiim u ah dabaylaha iftiinka ifaya si ay u shaqeeyaan.
Isku xirka pn ee gudaha diode wuxuu abuuraa caqabad Waxay u ogolaataa hadda inuu u socdo hal jiho oo keliya.
Waxaad u baahan tahay inaad ku xidhid anode-ka diode-ka iftiinka iftiinka dhinaca dhinaca wanaagsan ee korontada. Cathode waxay u socotaa dhinaca xun.
Haddi aad khalad ka hesho, LED-yadaadu ma ifin doonaan. Waxaa laga yaabaa inaad aragto waxba dhacaya, ama LED-ku wuu fashilmi karaa. Had iyo jeer hubi calaamadaha LED-ka ka hor intaadan dhisin wareeggaaga.
Ilaalinta danab gadaal
Waxaad doonaysaa in LED-yadaadu ay jiraan wakhti dheer. Korontada rogaal celiska ah waxay dhaawici kartaa si degdeg ah. Isticmaalka diodes ee wareeggaaga waxay kaa caawinaysaa inaad ka ilaaliso dabaylaha iftiinkaaga dhibaatadan. Diodes, gaar ahaan Schottky diodes, waxay u dhaqmaan sida gaashaan.

Markaad doorato diode ilaalinta dabada gadaale, raadi mid leh qiimaynta ugu sarreysa Voltage (PIV) ee ku habboon nidaamkaaga. Tusaale ahaan, haddii aad isticmaasho sahay koronto oo 12V ah, dooro diode leh PIV ugu yaraan 20V ah. Baabuurta, korontadu way ku dhici kartaa, marka waxa laga yaabaa inaad u baahato diode leh PIV 50V ama ka badan. Schottky diodes si fiican ayey u shaqeeyaan sababtoo ah waxay leeyihiin hoos u dhac danab hore ah oo dhaqso u beddela. Tani waxay ka dhigaysaa inay ku fiican yihiin ilaalinta diode-yada iftiinka xasaasiga ah.
Xaddidaadda hadda ee resistors
Waxaad u baahan tahay inaad xakamayso qadarka hadda socda ee LED-yadaada. Haddii aad ka gudubto resistor xaddidaya hadda, LED-yadaadu si degdeg ah ayey u gubi karaan. Iska caabbigu waxa uu ku ilaalinayaa socodka hore heer ammaan ah. La'aanteed, LED-yadu way libiqsan karaan, aad u kululaan karaan, ama joojin karaan shaqada. Sahayda korontadu waxay soo diri kartaa kor u kaca hadda markaad shido. Korodhkan ayaa baabi'in kara diode-kaaga iftiimaya haddii aanad isticmaalin iska caabin.
Halkan waxaa ah hage degdeg ah oo lagu dooranayo iska caabiyaha saxda ah ee midabada caadiga ah ee LED:
Midabka LED | Dhibic koronto (V) | Qiimaha iska caabinta ee lagu taliyay (Ohms) |

Sida ay u shaqeeyaan dabaylaha iftiinka-bixiya
Waxaa laga yaabaa inaad la yaabto sida dyodoyinka soo baxa iftiinka dhab ahaantii dhalaalaya. Markaad ku xidho LED-yada isha korantada, korontadu waxay soo martaa isgoysyada pn ee gudaha diode kasta oo iftiimiya. Electrons iyo godad ayaa ku kulmaya isgoyskan. Isdhexgalkoodu wuxuu sii daayaa tamar ahaan iftiin muuqda. Qalabka ku dhex jira LED-yada ayaa go'aamiya midabka iyo dhalaalka. Qaar ka mid ah LED-yada waxay isticmaalaan xeryahooda gaarka ah si ay u abuuraan buluug, cagaar, ama xitaa iftiinka ultraviolet. Habka loo dhisay isgoyska pn wuxuu saameeyaa inta iftiinka aad hesho iyo sida hufan ee uu u iftiimo. Haddii aad rabto ledhyo xoog badan, waxaad u baahan tahay nashqado u oggolaanaya iftiin badan oo ka baxsan diode-ka.

Mararka qaarkood, waxaad arkaysaa darajo fidsan oo ku taal cidhifka LED-ka. Darajadaas waxay calaamad u tahay cathode. Gudaha LED-ka, qaybta weyn sidoo kale waa cathode. Dusha sare ee LED-yada waxay inta badan leeyihiin calaamado yaryar si ay u muujiyaan Had iyo jeer iska hubi calaamadahan ka hor intaadan ku darin dabaylaha iftiinka iftiinka wareeggaaga.

Diode-yada caadiga ah waxay xukumaan jihada hadda jirta. LED-yadu sidoo kale sidaas ayay sameeyaan, laakiin sidoo kale waxay sameeyaan iftiin. Alaabta ku dhex jirta daaydhiyeyaasha iftiinka iftiinka way ka duwan yihiin daaydhka silikoon ee caadiga ah. Nalalka LED-yadu waxay adeegsadaan iskudhisyo iftiimin kara markay korontadu dhex marto. Diodes-ka caadiga ah ma soo saaro iftiin. Farqi kale oo weyn ayaa ah inta uu le'eg yahay korantada roga ah ee mid kastaa uu awoodo. Inta badan LED-yada waxay leeyihiin qiimeynta danab ka hooseeya kuwa caadiga ah. Haddii aad ku shubto danab badan oo rogaal celis ah diode-yada iftiinka, si fudud ayay u jebi karaan.
