Korontada Joogtada ah ee LED-ka
Korontada joogtada ah ee LED-ka waxaa loo isticmaalaa in lagu bixiyo nalalka LED-ka. Maaddaama ay hadda ku qulqulayaan LED-yada si toos ah loo ogaado loona xakameeyo inta lagu jiro hawlgalka sahayda korontada, looma baahna in laga walwalo in qulqulka xad-dhaafka ah ee hadda socda ee LED-yada xilligan la joogo, looma baahna in laga walwalo wareegga-gaaban ee culeyska, jebinta korontada.
Habka wadista joogtada ah ee hadda jira waxay ka fogaan kartaa isbeddelka korantada hore ee LED waxayna sababi kartaa isbeddelka hadda jira, halka hadda joogtada ahi uu ka dhigayo iftiinka LED-ka mid deggan, iyo sidoo kale waxay ku habboon tahay warshadda nalalka LED si loo hubiyo joogteynta alaabta marka wax soo saarka ballaaran la fuliyo. Sidaa darteed, warshado badan ayaa horeyba si buuxda uga warqabay muhiimada awoodda wadista. Qaar badan oo ka mid ah soosaarayaasha nalalka LED-ka ayaa ka tagay qaabka joogtada ah ee tamarta, waxayna adeegsadeen qiimaha joogtada ah ee qiimaha joogtada ah si ay u kaxeeyaan iftiinka LED-ka.
Qaar ka mid ah soosaarayaasha ayaa ka walaacsan in doorashada capacitors electrolytic ee guddiga korantada ay saameyn doonto nolosha sahayda korontada. Dhab ahaantii, waa isfaham la'aan. Tusaale ahaan, haddii 105 darajo la isticmaalo, capacitor heerkulka sare ee electrolytic ee nolosha 8000 saacadood waxaa lagu dhimi doonaa 10 darajo sida ku cad rajada nolosha hadda ee capacitors electrolytic, iyo rajada nolosha darawalka labanlaaban, sidaas darteed waxa uu leeyahay nolol shaqo Saacadaha 16,000 ee jawiga 95, nolosha shaqada ee saacadaha 32,000 ee jawiga 85, iyo nolosha shaqada ee saacadaha 64,000 ee jawiga 75. Haddii heerkulka dhabta ah ee hawlgalka uu hooseeyo, markaa noloshu way dheeraan doontaa! Marka laga eego aragtidan, wax saameyn ah kuma laha nolosha awoodda wadista ilaa inta aan doorano capacitors electrolytic tayo sare leh.
Waxa kale oo jira hal dhibic oo mudan in fiiro gaar ah loo yeesho shirkadaha nalalka LED: Sida LED-ku sii deyn doono kulayl badan inta lagu jiro habka shaqada, heerkulka shaqada ee iftiinka ayaa si degdeg ah u kici doona. Korodhka awoodda LED-ka, ayaa ka weyn saamaynta kuleyliyaha. Kordhinta heerkulka jilibka LED wuxuu u horseedi doonaa waxqabadka aaladda iftiiminta. Isbeddelka iyo waxtarka beddelka elektro-optical-ka waa la dhimay, oo xitaa guul darreystay marka xaaladdu ay halis tahay. Marka loo eego tijaabada tijaabada, qulqulka iftiinka ayaa hoos u dhacaya 3% 5 darajo Celsius korodhka heerkulka LED-ka. Sidaa darteed, nalka LED-ku waa inuu fiiro gaar ah u yeeshaa kulaylka iftiinka iftiinka LED laftiisa. Isku day inaad kordhiso aagga kulaylka ee isha iftiinka LED sida ugu macquulsan, iskuna day inaad hoos u dhigto heerkulka shaqada ee LED laftiisa. Haddii shuruuduhu oggolaadaan, way fiicantahay in la kala saaro qaybta korontada iyo qaybta isha iftiinka. Laguma talinayo in lagu daba galo mugga yar si indho la'aan ah oo la iska indhatiro heerkulka hawlgalka ee nalka iyo korontada.
