Taw qhia txog kev txuag lub teeb ci
Siab luminous efficiency ntawm LED teeb
LED teeb pom kev zoo: tuaj yeem xa mus rau 50-200 lm / w, thiab zoo monochromism, nqaim spectrum, tsis tas yuav tsum tau liming, tuaj yeem ncaj tuaj yeem pom lub teeb pom kev.
Qes zog ntawm LED lub teeb
Lub hwj huam ntawm LED ib qho transistor yog 0.03-0.06 W, siv DC tsav, thiab qhov kev taw qhia tsav tsheb ntawm LED ib qho transistor yog 1.5-3.5 V. Tam sim no 15-18 mA siab ceev ceev thiab yuav ua tiav ntawm cov qib high frequencies. Thaum siv tib lub teeb pom kev zoo, lub hwj huam siv tau yog 1 / 10,000 ntawm cov roj teeb thiab 1/2 ntawm lub raj roj fluorescent. Nyuaj kev kwv yees hais tias yog lub teeb ci zoo li 2 zaug siab tshaj ntawm cov roj fluorescent, hloov ib nrab ntawm Japanese teeb roj teeb thiab cov roj teeb muaj fluorescence nrog LED, nws yuav txuag tau li 6 billion liters txhua lub xyoo. Crude roj, tib cov nyhuv ntawm ib lub teeb ntim ntau tshaj 40 watts, thiab siv cov hwj huam hluav taws xob hauv ib chav tsev yog 18 watts.
Kev pab lub neej ntev ntawm LED teeb
Incandescent teeb, fluorescent teeb thiab halogen tungsten teeb txais cov yam ntxwv ntawm hluav taws xob lub teeb hluav taws xob, filament hlawv yooj yim, thermal deposition thiab lub teeb attenuation, thaum LED teeb yog me me loj, lub teeb hauv qhov hnyav, thiab encapsulated hauv epoxy re. Nws tuaj yeem tiv taus cov tshuab muaj zog thiab qhov teeb meem, thiab tsis yooj yim rau kev tawg. Qhov nruab nrab ntawm LED teeb yog 30,000 rau 50,000 teev. Qhov kev pab cuam lub teeb ntawm LED teeb tuaj yeem ncav 3-5 teev. Hauv xyoo 2000, kev txo nqi ntawm cov roj teeb tau zoo heev kom tsis txhob muaj qhov teeb meem ntawm hloov lub teeb nquag.
LED lub teeb ci tau muaj kev nyab xeeb thiab txhim khu kev ntseeg
Tsis tshua muaj calorific nqi, tsis muaj thermal hluav taws xob, txias teeb ci, kov kov, tswj tau qhov tseeb thiab luminous lub kaum ntse ntse, lub teeb xim thiab, tsis pom kev, tsis muaj mercury, sodium ntsiab thiab lwm yam tshuaj uas yuav ua teeb meem kev noj qab haus huv.
