Lub Luminous Txoj Cai Ntawm LED Tube Teeb

LED tube teeb yog tsuas yog illuminated los ntawm diodes, thiab lawv lifespan nyob ntawm cov khoom-state LED teeb qhov chaw thiab cov tsav tsheb thiab cua txias qhov chaw. Nyob rau hauv 2012, lub neej ntawm LED tube teeb tau mus txog ntau tshaj 80000 teev. Nrog rau kev tshawb fawb tsis tu ncua thiab kev siv dav dav ntawm LED thev naus laus zis, kev tsav tsheb thiab kev ua kom txias kuj tau mus txog lub xeev zoo tagnrho. Piv nrog rau cov teeb pom kev zoo tib yam halogen tube teeb, lub neej ntev ntawm cov teeb pom kev zoo LED lub teeb ntawm lub khw tau pib mus txog 80000 teev.

Lub davhlau ya nyob twg voltage ntawm PN hlws ris ua ib qho teeb meem muaj peev xwm. Thaum siv qhov kev tsis ncaj ncees rau pem hauv ntej, qhov cuam tshuam muaj peev xwm txo qis, thiab feem ntau cov neeg nqa khoom hauv cheeb tsam P thiab N sib txawv ntawm ib leeg. Vim tias qhov muaj zog hluav taws xob ntau dua li qhov kev txav mus los, ntau tus electrons yuav kis mus rau thaj tsam P, ua rau muaj kev txhaj tshuaj ntawm cov neeg nqa khoom tsawg rau hauv cheeb tsam P. Cov electrons recombine nrog lub qhov ntawm lub valence band, thiab lub zog tau txais thaum lub sij hawm recombination yog tso tawm nyob rau hauv daim ntawv ntawm lub teeb lub zog. Qhov no yog lub hauv paus ntsiab lus ntawm PN junction luminescence.
