Diidmada kulaylka ee LED-yada awoodda sare leh
LED waa aalad optoelectronic ah, kaliya 15% ~ 25% tamarta korantada ayaa loo rogi doonaa tamar iftiin inta lagu jiro hawlgalkeeda, inta soo hartayna tamarta korantada ayaa ku dhow.waxaa loo beddelaa tamarta kulaylka, taasoo ka dhigaysa heerkulka LED-ga sare. LED-yada awoodda sare leh, kuleylka kuleylka waa arrin weyn oo u baahan baaritaan gaar ah. Tusaale ahaan, haddii wax ku oolnimada beddelka korantada ee 10W LED cad ay tahay 20% sida kor ku xusan, taas oo ah, 8W tamarta korantada ayaa loo beddelaa tamarta kulaylka. Haddii aan lagu darin qiyaasaha kuleylka kuleylka, heerkulka udubdhexaadka ah ee tamarta sare ee LED si degdeg ah ayuu u kici doonaa. Marka qiimihiisa TJ uu kor u kaco heerkulka ugu sarreeya ee la oggol yahay (badanaa 150 ℃), LED-ga awoodda sare leh ayaa dhaawacmi doona kulaylka dartood. Sidaa darteed, naqshadeynta nalalka ED ee awoodda sare leh, shaqada naqshadeynta ugu muhiimsan waa naqshadeynta kuleylka.
Intaa waxaa dheer, xisaabinta kuleylka kulaylka ee qalabka korontada guud (sida korontada 1C), ilaa inta heerkulka isgoysku uu ka yar yahay heerkulka ugu sarreeya ee la oggol yahay (guud ahaan 125 ° C), waa ku filan. Laakin qaabaynta kuleyliyaha tamarta sare ee LED, shuruudaha TJ VALUE aad ayuu uga hooseeyaa 125℃. Sababta ayaa ah in TJ ay saameyn weyn ku leedahay heerka soo saarista iftiinka iyo cimriga LED-ka: sare u kaca TJ, hoos u dhaca heerka iftiinka iftiinka iyo cimriga gaaban ee LED-ka.
Dariiqa kuleylka kuleylka ee LED-ka awoodda sare.
LED-yada awoodda sare leh waxay muhiimad weyn siinayaan kala-baxa kulaylka ee naqshadeynta qaabdhismeedka. Qaar ka mid ah naqshadeeyayaasha waxay leeyihiin bir weyn oo kuleylka kuleylka hoostiisa ah, kaas oo ka dhigi kara kulaylka dhimashada inuu ku faafo dibadda iyada oo loo marayo suufka kuleylka. Nalalka tamarta sare leh waxaa lagu iibiyaa sabuurad daabacan (PCB). Dusha hoose ee suufka kuleyliyaha waxaa lagu dhejiyay dusha naxaasta ee PCB-ga, iyo lakabka weyn ee naxaasta leh ayaa loo isticmaalaa sida dusha sare ee kulaylka. Si loo hagaajiyo waxtarka daadinta kulaylka, PCB-lakab-lakab ah oo naxaas ah ayaa la isticmaalaa. Tani waa mid ka mid ah qaababka ugu fudud ee daadinta kulaylka.
