Taw qhia rau LED qhov muag teev

Lub teeb LED yog lub teeb pom kev zoo uas siv LEDs (lub teeb -emitting diodes) ua nws lub teeb ci. Nws cov duab zoo ib yam li cov teeb pom kev zoo ib txwm muaj, yog li lub npe "lub teeb teeb." Technically, lub teeb LED ua haujlwm los ntawm kev siv hluav taws xob tam sim no los txhawb cov hluav taws xob hauv LED nti. Thaum cov electrons recombine nrog lub qhov, lub zog tso tawm raws li photons, yog li ua tiav cov teeb pom kev zoo. Piv rau cov khoom siv hluav taws xob thiab cov teeb fluorescent, txoj kev ntawm lub teeb emission no muaj ntau dua luminous efficiency thiab qis zog noj. Lub luminous efficiency ntawm LED qhov muag teev feem ntau ncav cuag 80-120 lumens ib watt, deb tshaj li ntawm kwv yees li 10 lumens ib watt ntawm incandescent qhov muag teev thiab tseem tshaj 50-70 lumens ib watt ntawm fluorescent teeb.
