Raws li kev thov thoob ntiaj teb rau kev txhim kho kom ruaj khov tau nce ntxiv, LED (Light Emitting Diode) thev naus laus zis tau ua lub luag haujlwm tseem ceeb.Tsab ntawv xov xwm no yuav tshawb txog lub luag haujlwm ntawm LED thev naus laus zis hauv kev txhim kho kom ruaj khov thiab qhia nws cov ntawv thov hauv kev txuag hluav taws xob, kev tiv thaiv ib puag ncig thiab kev ruaj ntseg hauv zej zog.

Ua ntej, LED thev naus laus zis tau ua lub luag haujlwm tseem ceeb hauv kev txuag hluav taws xob.Cov teeb pom kev zoo ib txwm muaj thiab cov teeb fluorescent muaj ntau lub zog poob hauv cov txheej txheem ntawm lub zog hloov pauv, thiab LEDs tuaj yeem hloov hluav taws xob ntau dua rau hauv lub teeb pom kev thiab muaj zog dua.Los ntawm kev siv loj-loj ntawm LED teeb pom kev zoo, kev siv hluav taws xob tuaj yeem txo qis, qhov kev thov rau cov khoom siv hluav taws xob ib txwm muaj peev xwm txo tau, yog li txhawb kev txhim kho lub zog ruaj khov.

Thib ob, LED thev naus laus zis muaj txiaj ntsig zoo hauv kev tiv thaiv ib puag ncig.Cov teeb pom kev zoo ib txwm muaj thiab cov teeb fluorescent muaj cov khoom tsis zoo xws li mercury, ua rau muaj kuab paug thiab muaj kev phom sij rau ib puag ncig.Cov teeb ci LED tsis muaj cov khoom tsis zoo, thiab cov hluav taws xob ultraviolet thiab infrared yuav tsis tsim thaum siv, uas txo qhov cuam tshuam rau ib puag ncig thiab tib neeg lub cev.LED lub neej ntev thiab rov ua dua tshiab kuj txo cov khoom pov tseg thiab txhawb kev rov ua dua tshiab.

Tsis tas li ntawd, LED thev naus laus zis tseem ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg hauv zej zog.LED teeb pom kev zoo muaj lub neej ua haujlwm ntev thiab cov nqi kho mob tsawg, txo qhov zaus ntawm kev hloov thiab kev saib xyuas cov chaw teeb pom kev zoo, thiab txuag cov peev txheej thiab tib neeg cov nqi.LED lub teeb hloov kho thiab xim ua haujlwm muab qhov chaw zoo nkauj dua thiab tus kheej lub teeb pom kev zoo, uas txhim kho tib neeg lub neej zoo.Nyob rau tib lub sijhawm, kev siv dav dav ntawm LED kuj tsim kev ua haujlwm rau kev lag luam teeb pom kev zoo thiab txhawb kev txhim kho kev lag luam ruaj khov.
