"Heerkulka isgoysyada LED" maaha mid aad u yaqaan dadka intooda badan, laakiin xitaa dadka ku jira warshadaha LED!Hadda aan si faahfaahsan u sharaxno.MarkaLED wuxuu shaqeeyaa, xaaladaha soo socda waxay kor u qaadi karaan heerkulka isgoysyada inuu kor u kaco heerar kala duwan.

1. Waxaa lagu caddeeyey dhaqamo badan in xaddidaadda wax-soo-saarka iftiinka ay tahay sababta ugu weyn ee kororka heerkulka is-goyska LED.Waqtigan xaadirka ah, korriinka walxaha horumaray iyo tignoolajiyada wax-soo-saarka ka kooban waxay u rogi karaan inta badan tamarta korantada ee horseedka tamarta shucaaca iftiinka.Si kastaba ha ahaatee, ay sabab u tahay index refractive aadka u weyn eechip LEDwax marka la barbar dhigo dhexdhexaadka ah ee ku xeeran, inta badan photons (> 90%) ee chip ma si habsami leh u buuxdhaafi karin interface, iyo guud ahaan milicsiga dhacdaa interface u dhexeeya chip iyo dhexdhexaad ah, Waxay ku soo laabtay gudaha chip iyo ugu dambeyntii la nuugo. by qalabka chip ama substrate iyada oo loo marayo milicsiga gudaha badan oo badan, oo uu noqdo kulayl qaab gariir sharooto, kaas oo kor u kacaya heerkulka isgoysyada.

2, Sababtoo ah isgoysyada pn ma noqon karto mid aad u qumman, waxtarka duritaanka curiyaha ma gaari doono 100%, taas oo ah, marka LED-gu uu shaqeeyo, marka lagu daro lacagta lagu duro (daloolka) ee aagga n ee aagga P, n aagga sidoo kale waxay ku shubi doontaa lacag (elektaroon) aagga P.Guud ahaan, duritaanka kharashka ee nooca dambe ma soo saari doono saamaynta indhaha, laakiin waxaa loo isticmaali doonaa qaab kuleyl.Xitaa qaybta faa'iidada leh ee kharashka la isku duray ma wada noqon doonto iftiin, qaarna ugu dambeyntii waxay noqonayaan kulayl marka lagu daro wasakh ama cilladaha gobolka isgoyska.

3, The qaab dhismeedka electrode liidata ee element ah, wax ka mid ah substrate lakabka daaqadda ama aagga isgoyska iyo xabagta lacagta conductive oo dhan waxay leeyihiin qiimo iska caabin gaar ah.Iska caabbintan ayaa midba midka kale ku xiran yahay si ay u sameeyaan iska caabin taxane ah oo ahelement LED.Marka uu hadda ku qulqulo isgoyska pn, wuxuu sidoo kale ku qulquli doonaa iska caabiyeyaashaas, taasoo keentay kulaylka Joule, taasoo keentay kororka heerkulka chip ama heerkulka isgoysyada.

Dabcan, horumarka sayniska iyo tignoolajiyada, sababta ugu weyn ee aynaan u fahmi karin ifafaalaha kore mid mid ayaa ah in aynaan mustaqbalka mid mid u fahmi karin.Dabcan, mid mid uma fahmi karno horumarka sayniska iyo tignoolajiyada!
