Rau Vim Li Cas Rau Qhov Teeb Nruab Nrab LED Hlav Xim Hloov
Sep 17, 2018
Hauv cov teeb ci qhia txog LED, lub teeb lub teeb yog qhov sib thooj uas siv ntau tshaj plaws, tab sis lub thawv ntawv thiab lub teeb phaj yog siv thaum siv, tsuav nws yog dab tsi? Hnub no, Xiaobian yuav qhia rau koj tias yog vim li cas uas cuam tshuam rau cov xim ntawm cov teeb ci teeb ntawm LED teeb.
Cov qauv ntawm lub teeb lub thawv xws li: lead, bracket, encapsulant, tsev hlua, LED nti, khoom siv lead ua kua thiab phosphor. LED teeb poob xim tsis ua hauj lwm yog ze rau nws cov khoom muaj pes tsawg leeg, qauv, ntim txheej txheem thiab siv tej yam kev mob.
Kev mob kev nyuab siab
1 Nyob txawv teb chaws teeb meem nyob rau hauv lub encapsulant
Cov tsos ntawm qhov poob ntawm lub teeb poob teeb yog qhov sib xyaw thiab blackened, mas vim nws yog tswvcuab thaum lub sijhawm txheej txheem.
2 Lub khauj khuav pob txha yog chiv tau tawg ua kom muaj kev sib daj sib deev
Phosphor sedimentation
Tom qab teeb lub teeb raug muab tso rau hauv ib qho teeb taws teeb, nws muab cia rau hauv lub tsev muag khoom. Yog hais tias nws cia rau ntev dhau lawm, phosphor deposition yuav tshwm sim, uas ua rau cov dispersion vim inconsistent lub teeb refraction qauv, uas ua rau xim kub hloov thiab teeb lub teeb txig sis.
Ua rau ntawm txoj hlua
1 lub cev txawv lub cev qias neeg bracket
2 stent corrosion
3 bracket plating zoo yog tsis zoo
