Mabda'a Iftiinka leh ee Laba-midab LED-kuul

Diyoode ee iftiinka ah waxaa inta badan loogu heyna (GA), arsenic (AS), fosforus (P), nitrogen (n). Marka elektarooniga iyo daloolka la isku daro, wuxuu soo saari karaa iftiin muuqda, sidaas darteed waxaa loo isticmaali karaa in la sameeyo diode iftiin leh. Kuullaha LED-ka waxaa badanaa lagu dabaqaa wareegyada iyo aaladaha sida nalalka tilmaame, ama qaab ama bandhig dhijitaal ah. Midabka iftiinka leh iyo waxtarka iftiinka iftiinka iftiinka iftiinka LED-ku waxay la xiriiraan qalabka iyo hababka samaynta LEDs. Waqtigan xaadirka ah, nalalka LED-ka ee leh saddex midab oo casaan, cagaar, iyo buluug ah ayaa si ballaaran loo isticmaalaa. Mawjada dhererka midabada kala duwan ayaa sidoo kale kala duwan. Guud ahaan, hoos u dhaca cadaadiska PN ayaa lagu go'aamin karaa si loo go'aamiyo midabka mawjadaha dhererka ee muraayadaha dhalaalaya. 1. Waa maxay qaab-dhismeedka koobabka ee labada-midabka LED-light-emitting diode?. Sababta keentay in labada midab ee LED-light-emitting diode ay u soo saari karaan laba midab oo iftiin ah ayaa inta badan ah in la xidho laba midab oo kala duwan oo jajab ah oo isku mid ah. Si fudud loo dhigo, qaab-dhismeedkeedu waxa uu ag yaal xudunta tuubada ee diode-ka monochrome ee caadiga ah, ka dibna ku rakib unug kale oo midab leh. Labada midab ee LED waxaa loo qaybin karaa laba cagood oo aan lahayn kuul laba midab leh oo LED ah, iyo laba-legged co-yin -yang laba-midab leh nalalka LED-ka. Marka labaad, mabda'a iftiinka iftiinka iftiinka ee saameynta saameynta iftiinka laba-midabka LED-ka ee aan dabacsanayn waa laba biin. Tusaale ahaan, waxaa jira laba biin oo casaan iyo cagaar ah oo LED-yada dhalaalaya ee aan dabaylaha ahayn. Alxanka cagaha aad u daran iyo kuwa gaaban, tiirka n iyo alxanka cagta dheer. Marka hadda uu ka soo qulqulo cago dhaadheer ilaa cago gaaban, laambada LED-ka ee casaanka iyo cagaarka ah ee laba-midab leh ayaa si caadi ah u shaqeeya, iftiinka cagaaranna ma shaqeeyo sababtoo ah hadda wuxuu ka soo qulqulayaa cag gaaban ilaa cag dheer, iftiinka cagaarka ah ee iftiinka cagaaran. Laambadaha LED-ka ee aan-polar-ka ahayn ee casaanka ah iyo cagaarka laba-midabka leh waa caadi, iftiinka cagaaran waa caadi Shaqo, nalalka guduudan ma shaqeeyaan, si loo gaaro ujeeddada lagu xakameynayo socodka hadda ee laba midab oo casaan iyo cagaar ah. Saddex, saddex-lugood co -yin -co -aode laba-midab LED-kuul iftiin leh, saddex-lugood laba-midab LED iftiin-mitting diode, laba midab kala duwan oo ka mid ah koofiyadaha tuubooyinka wadaagaan hal tiir. Saddexda biin ayaa kala duwan, oo lugta dadweynaha ee ugu dheer ee dhexda waa dhammaadka dadweynaha. Saddex-foot iyo laba-midab LED kuul kuul waxaa loo qaybin karaa laba nooc: cathode caadiga ah iyo LED anode caadiga ah sida ay polarity kala duwan ee biinanka dhamaadka dadweynaha. Markaa. Sidee loo kala saaraa saddexda lugood ee laba-midabka LED-ka ee nalalka iftiinka leh? Farqiga u dhexeeya Shuuciga Yin iyo Yang inta badan waa in la arko tiirarka togan iyo kuwa taban ee biinka dhammaadka dadweynaha ee ugu dheer. Haddii biinanka dadweynuhu uu taban yahay, waa tiirka Gongchen LED LED light-etting diode. LED-ga hadda socda guud ahaan waxa uu ka soo qulqulaa korantada togan, korantada taban ayaana ka soo baxda.
