Dab tsi yog qhov zoo ntawm LED qij tshaj qhov muag teev
1. Kev txuag hluav taws xob. Piv nrog cov roj teeb ib txwm muaj, nws tuaj yeem txuag ntau dua 80% ntawm hluav taws xob, thiab qhov ci ci yog 10 npaug ntawm cov teeb roj teeb nyob hauv tib lub zog;
2. Lub neej ntev ntev, ntau dua 50,000 teev, ntau dua 50 npaug ntawm cov tsoos tungsten filament teeb
3. Tsis muaj cov pa phem, xws li mercury
4. Tsis muaj hluav taws xob, xws li ultraviolet rays
5. Kev ua haujlwm seismic zoo thiab ruaj khov qauv
6. Tsawg zog ua haujlwm, nyab xeeb thiab ntseeg tau. Qhov kub thiab txias ≤60 ℃ (thaum ntsuas kub Ta=25 ℃)
