Xiriirka ka dhexeeya tayada nalalka LED-ka iyo korontada
LED waxay leedahay faa'iidooyin badan sida ilaalinta deegaanka, nolosha dheer, waxtarka sare ee photoelectric (waxtarka iftiinka hadda wuxuu gaaray 130LM / W ~ 140LM / W), caabbinta dhulgariirka, iwm. Sanadihii la soo dhaafay, codsigeeda si degdeg ah ayaa loo horumariyay warshado kala duwan. Aragti ahaan, nolosha adeegga LED-ku waa 100,000 saacadood, laakiin habka codsiga dhabta ah, qaar ka mid ah naqshadeeyayaasha nalalka LED waxay leeyihiin faham ku filan ama xulashada khaldan ee awoodda wadista LED ama si indho la'aan ah u raacaan kharash yar. Natiijo ahaan, nolosha alaabta nalalka LED-ka ayaa si weyn loo gaabiyay. Nolosha nalalka LED-ka ee liita ayaa ka yar saacadaha 2000 oo xitaa ka hooseeya. Natiijadu waxay tahay in faa'iidooyinka nalalka LED aan lagu muujin karin codsiga.
Sababo gaar ah oo ka mid ah farsamaynta iyo wax soo saarka LED, sifooyinka hadda iyo korantada ee LED-yada ay soo saaraan saarayaasha kala duwan iyo xitaa isla saaraha isku midka ah ee badeecadaha ayaa leh kala duwanaansho shakhsiyeed oo waaweyn. Qaadashada qeexitaanka caadiga ah ee awoodda sare ee 1W cad LED tusaale ahaan, marka loo eego xeerarka kala duwanaanshaha hadda iyo korantada ee LED, sharraxaad kooban ayaa la bixiyaa. Guud ahaan, danabka hore ee codsiga iftiinka cad ee 1W wuxuu ku saabsan yahay 3.0-3.6V, taas oo ah, marka lagu calaamadiyo sida 1W LED. Marka uu hadda ku dhex socdo 350mA, korontadu waxay noqon kartaa 3.1V, ama waxay noqon kartaa qiyam kale oo ah 3.2V ama 3.5V. Si loo hubiyo nolosha 1WLED, soo saaraha guud ee LED wuxuu ku talinayaa in warshadda nalalka ay isticmaasho 350mA hadda. Marka korantada hore ee LED-ku gaadho 350 mA, kororka yar ee korantada hore ee LED-ku wuxuu sababi doonaa in LED-ga hadda socda uu si aad ah kor ugu kaco, taasoo keenaysa heerkulka LED-ku inuu si toos ah kor ugu kaco, taas oo dardargelinaysa suuska iftiinka LED. Si loo gaabiyo nolosha LED-ka oo xitaa la gubo LED-ka marka ay halis tahay. Sababo la xiriira kala soocida korantada iyo isbeddelada hadda ee LED-ka, shuruudo adag ayaa lagu soo rogay sahayda korantada ee wadista LED-ka.
Darawalka LED waa furaha nalalka LED-ka. Waxay la mid tahay qalbiga qofka. Si loo soo saaro nalalka LED-yada tayada sare leh ee nalalka, waxaa lagama maarmaan ah in laga tago danab joogto ah si loo wado LEDs.
Qaar badan oo ka mid ah dhirta baakadaha LED-ka ee awoodda sare leh ayaa hadda xira nalalka LED-yada gaarka ah si isku mid ah iyo taxane si ay u soo saaraan hal 20W, 30W ama 50W ama 100W ama koronto ka sarreeya LED. Inkasta oo ka hor xirmada, ay si adag loo xushay oo isbarbardhigay, waxaa jira daraasiin iyo boqolaal LEDs shakhsi ah sababtoo ah tirada yar ee gudaha. Sidaa darteed, baakadaha awoodda sare ee LED-yada ayaa weli leh farqi weyn oo xagga tamarta iyo hadda ah. Marka la barbardhigo hal LED (guud ahaan hal iftiin cad, iftiin cagaaran, iftiin buluug ah oo shaqeynaya 2.7-4V, iftiin hal casaan ah, nalka jaalaha ah, korantada shaqada iftiinka orange ee 1.7-2.5V) cabbirada xitaa way ka duwan yihiin!
Waqtigan xaadirka ah, alaabta nalalka LED (sida ilaaliyaha, koobabka laambada, nalalka saadaalinta, nalalka beerta, iwm.) oo ay soo saaraan warshado badan ayaa isticmaala caabbinta, awoodda iyo dhimista tamarta, ka dibna ku dar diode Zener si ay u siiso awoodda LED-yada. Waxaa jira cillado waaweyn. Marka hore, waa mid aan waxtar lahayn. Waxay ku baabbi'isaa awood badan on resistor hoos-down. Waxa laga yaabaa inay xitaa dhaafto awoodda ay isticmaasho LED-ku, mana bixin karto wadista hadda sareeysa. Marka hadda uu ka weyn yahay, awoodda la baabbi'iyey on resistor-hoos u noqon lahaa weyn, LED hadda lama dammaanad qaadi karo in ay ka badan tahay shuruudaha shaqo ee caadiga ah. Marka la naqshadeynayo sheyga, korantada guud ahaan LED-ka waxaa loo isticmaalaa in lagu kaxeeyo korontada, taas oo ah kharashka iftiinka LED. LED-ku waxa u kaxeeya caabbinta iyo awoodda hoos-u-dhaca, iyo dhalaalka LED-ka lama dejin karo. Marka korantadu ay yaraato, iftiinka iftiinka LED-ku wuxuu noqdaa mid mugdi ah, marka korantadu ay sarreeyso, iftiinka iftiinka ayaa noqda mid dhalaalaya. Dabcan, faa'iidada ugu weyn ee iska caabinta iyo karti-hoosaadka darawalnimada LED-yada waa qiimaha jaban. Sidaa darteed, qaar ka mid ah shirkadaha nalalka LED-ka ayaa wali isticmaala habkan.
Qaar ka mid ah soo-saareyaasha, si loo yareeyo qiimaha badeecada, iyadoo la adeegsanayo koronto joogto ah si loo wado LED-ka, waxay sidoo kale keentaa su'aalo taxane ah oo ku saabsan iftiinka aan sinnayn ee LED kasta ee wax soo saarka guud, LED-ku kuma shaqeyn karo gobolka ugu fiican, iwm. .
Wadista isha joogtada ah waa habka ugu wanaagsan ee wadista LED. Waxa wada il joogta ah oo hadda jirta. Looma baahna in lagu xidho caabiyeyaasha xaddidaya hadda ee wareegga wax soo saarka. Hadda ku qulqulaya LED-ka ma saameeyo isbeddelada tamarta korantada ee dibadda, isbeddelka heerkulka jawiga, iyo cabbirrada LED-yada ee gaarka ah. Saameyntu waa in la sii wado joogtaynta hadda jirta oo la siiyo ciyaar buuxda sifooyin kala duwan oo heer sare ah oo LED ah.
