Sharaxaad Faahfaahsan oo ku saabsan 4 Hab oo Isku Xiran oo loogu talagalay Darawalada LED-ka
Waqtigan xaadirka ah, inta badan alaabada LED-ka waxay qaataan qaab wadista hadda socota si ay ula jaanqaadaan astaamaha hawlgalka ee LED-yada. Si loo daboolo baahiyaha naqshadaha wareegga ee kala duwan, qaababka isku xirka caadiga ah ee LED-yada waxaa inta badan loo qaybiyaa afar nooc: isku-darka taxanaha, barbar socda, isku-darka taxanaha-isku-dhafka ah, iyo safka. Hab kastaa wuxuu leeyahay astaamo u gaar ah oo qaab-dhismeedka wareegga ah, faa'iidooyinka codsiga, iyo xaddidaadaha, kuwaas oo si faahfaahsan loogu faahfaahin doono hoos.
1. Habka Isku xirka Taxanaha
Qaab-dhismeedka asaasiga ah ee isku xirka taxanaha ah waa in lagu xiro LED-yada dhammaadka-ilaa-dhammaadka si taxane ah si loo sameeyo wareeg xiran. Marka la eego astaamaha hawlgalka, faa'iidooyinka asaasiga ah ee qaabkan isku xirka waa qaab-dhismeedka wareegga fudud, hawlgalka isku xirka ee ku habboon, iyo hadda socota dhammaan LED-yada oo si buuxda isugu xiran inta lagu jiro hawlgalka. Maadaama LED-yadu ay yihiin aaladaha caadiga ah ee hadda jira, joogteynta hadda waxay si toos ah u hubin kartaa xoogga iftiinka isku midka ah ee LED kasta, iyadoo laga fogaanayo kala duwanaanshaha iftiinka.
Waa in la ogaadaa in nooca korontada wadista ay saameyn doonto baaxadda saameynta cilladda ee wareegga taxanaha ah: haddii la isticmaalo koronto wadista danab joogto ah, marka mid ka mid ah LED-yada la gooyo, hadda wareegga oo dhan ayaa si weyn u kordhi doona. Marka hadda uu ka sarreeyo qiimaha la qiimeeyay ee LED-ka, aaladaha ku wareegsan LED-ka wareegga gaaban ayaa marka hore dhaawacmi doona, ka dibna dhammaan LED-yada xiga ayaa midba midka kale dhaawacmi doona; haddii la isticmaalo koronto wadista joogtada ah ee hadda socota, xitaa haddii mid ka mid ah LED-yada la xiro, hadda wareegga wali wuu sii ahaan karaa mid joogto ah, mana saameyn doono LED-yada kale. Si kastaba ha ahaatee, iyadoon loo eegin qaabka wadista ee la qaato, ilaa inta cillad wareeg furan oo LED ah ay dhacdo, xarigga iftiinka oo dhan lama shidi karo.
2. Habka Isku Xidhiidhka Isbarbardhigga ah
Astaanta qaab-dhismeedka ee isku xirka barbar socda ayaa ah in dhammaadka dhammaan LED-yada la isku daro oo la isku xiro siday u kala horreeyaan, taas oo ah, anodes-ka dhammaan LED-yada ayaa isku xiran oo cathodes-yadu way isku xiran yihiin. Habkan isku xirka, danabka LED- kasta waa mid gebi ahaanba siman, laakiin hadda socda ee dhex mara LED- kasta daruuri ma aha mid isku mid ah - xitaa haddii LED-yada isku midka ah ee qaabka iyo dufcadda qeexitaanka la doorto, qaybinta hadda jirta waxay noqon doontaa mid aan sinnayn sababtoo ah kala duwanaansho yar oo ku saabsan hababka wax soo saarka iyo wax soo saarka. Qaybinta hadda aan sinnayn waxay si toos ah u saamayn doontaa cimriga adeegga LED-yada. LED-yada leh hadda xad-dhaafka ah si dhakhso ah ayay u gabowdaan, cimrigooda adeegga si weyn ayaa loo soo gaabin doonaa, si fudud ayaana loo gubi doonaa ka dib isticmaalka muddada dheer.
Marka laga hadlayo kakanaanta wareegga, qaabka isku xirka barbar socda wuxuu la mid yahay qaabka isku xirka taxanaha, labaduba waa qaab-dhismeedyo wareeg oo fudud, laakiin kalsoonidu sidoo kale ma sarreyso. Gaar ahaan xaaladaha leh tiro badan oo LED ah, suurtagalnimada fashilka ayaa si weyn u kordhi doonta.
Waa in la ogaadaa in qaabka isku xirka barbar socda uu leeyahay shuruudo danab hooseeya isla markaana uu ku habboon yahay xaaladaha wadista danab hooseeya, laakiin waxaa jira laba dhibaato oo muhiim ah: marka hore, farqiga u dhexeeya hoos u dhaca danabka hore ee LED-yada kala duwan wuxuu horseedi doonaa iftiin aan iswaafaqsanayn, taasoo saameynaysa saameynta iftiinka; marka labaad, saameynta cilladdu waa mid gaar ah - haddii hal LED uu wareeg gaaban yahay, waxay sababi doontaa wareeg gaaban oo wareegga oo dhan ah, dhammaan LED-yaduna si caadi ah uma shaqeyn karaan; haddii hal LED uu wareeg furan yahay, marka la isticmaalayo darawalka hadda socda ee joogtada ah, hadda asal ahaan loo qoondeeyay LED-kan dhammaantood waxaa lagu dul saari doonaa LED-yada haray, taasoo horseedaysa dhaawac xad dhaaf ah oo ku yimaada LED-yada haray, halka isticmaalka darawalka danabka joogtada ah uusan saameyn ku yeelan doonin hawlgalka caadiga ah ee wareegga LED-ka oo dhan.
Habka isku-darka taxanaha-isku-dhafka ah waa isku-darka isku-xirka taxanaha iyo kuwa is-barbar socda. Qaab-dhismeedkiisa caadiga ah waa: marka hore, ku xidh dhowr LED oo taxane ah si aad u sameyso laan, ka dibna ku xidho laamo badan oo taxane ah oo barbar socda labada daraf ee korontada wadista ee LED-ka. Iyada oo la tixgelinayo in xuduudaha LED-yada shaqsiga ahi ay asal ahaan isku mid yihiin, qaabkan isku-xirka wuxuu hubin karaa in danabka dhammaan laamaha is-barbar socda uu siman yahay, iyo hadda ku jirta laan kasta oo taxane ah uu yahay mid isku mid ah, taas oo aan kaliya tixgelinayn faa'iidada isku-dheellitirka hadda ee qaabka isku-xirka taxanaha, laakiin sidoo kale wuxuu isku daraa astaamaha xasilloonida wareegga ee qaabka isku-xirka barbar socda.
Waa in la ogaadaa in faa'iidada ugu weyn ee qaabka isku-dhafka taxanaha-isku-dhafka ah ay tahay horumarinta isku-kalsoonida, gaar ahaan ku habboon xaaladaha nalalka awoodda sare leh ee leh tiro badan oo LED ah. Marka cillad LED ah ay ka dhacdo laan taxane ah, waxay saameyn doontaa oo keliya sii deynta iftiinka ee laantaas, laamaha kalena wali si caadi ah ayay u shaqeyn karaan. Marka la barbardhigo qaababka taxanaha ah iyo kuwa is barbar socda, heerka saameynta cilladda aad ayuu u yaraaday. Waqtigan xaadirka ah, inta badan nalalka LED-ka ee awoodda sare leh (sida nalalka daadadka LED-ka, nalalka warshadaha iyo macdanta LED-ka, iwm.) waxay qaataan qaabka isku-darka taxanaha-isku-dhafka ah, kaas oo aan kaliya dabooli karin baahida iftiinka awoodda sare leh, laakiin sidoo kale hubinaya isku-kalsoonida isticmaalka.
Fikradda naqshadaynta asaasiga ah ee qaabka isku xirka array waa "dib-u-soo-celin kooxeed". Qaab-dhismeedkeeda caadiga ah waa: samee laan leh 3 LEDs oo koox ahaan ah, koox kasta oo laamo ahna waxay ku xiran tahay saddexda terminaal ee kala duwan ee wax soo saarka Ua, Ub, iyo Uc ee darawalka siday u kala horreeyaan. Marka laga eego aragtida macquulka shaqada, marka dhammaan 3 LED ee laan ay caadi yihiin, 3 LED-yadu waxay isla markiiba iftiimiyaan; xitaa haddii 1 ama 2 LED oo laan ku jira ay furmaan, LED-yada haray wali si caadi ah ayay u shaqayn karaan, sidaas darteed hubinta in ugu yaraan hal LED oo koox kasta ku jira uu iftiin soo saaro.
