LED stands rau lub teeb-emitting diodes, thiab LED teeb Ua teeb pom kev zoo li 90 feem pua ntau dua qhov muag teev. Txhawm rau tsim lub teeb, hluav taws xob tam sim no dhau los ntawm microchip thiab teeb pom kev me me peb hu ua LEDs. Qhov tshwm sim ntawm qhov kev ua no yog pom lub teeb.
Puas LED teeb hluav taws kub?
Qhov zoo tshaj plaws ntawm LED teeb hla lub qhov muag teev yog lawv lub neej. Lub teeb taws teeb tau tsim kom kav ntev li 1,{1}} teev, tab sis LED teeb tau sim ua kom ntev li 100,000 teev. Qhov nruab nrab LED teeb lub teeb yuav tsis tas yuav hloov mus rau tsawg kawg 20 xyoo.
LED teeb tuaj yeem yog kev nqis peev uas txuag lub sijhawm thiab nyiaj txiag, tab sis muaj cov xwm txheej uas LED teeb yuav tsis kav ntev npaum li kev tshaj tawm. LEDs tuaj yeem tawg thiab hnav dhau sijhawm, ib yam li lwm yam teeb pom kev zoo, thiab cov xwm txheej hnyav tuaj yeem ua rau lawv hnav sai dua.
Feem ntau koj yuav pom LEDs uas qhia txog lub neej ntawm 5, 10, txog 20 xyoo. Qhov tseeb yog nws nyob ntawm lawv siv. Piv txwv li, yog tias lub teeb siv rau qhov nruab nrab ntawm xya teev nyob rau ib hnub thiab lub teeb muaj 25,000 teev, nws yuav kav yuav luag kaum xyoo. Qhov no yuav hloov pauv raws li cov xwm txheej thiab lub teeb rau ntev npaum li cas.
Thaum lub teeb ci LED kav ntev, lub teeb tso zis dims dhau lub sijhawm es tsis txhob raug kev txom nyem sai li sai tau xws li cov qij taws. Txawm hais tias ua haujlwm tsis zoo nyob rau lub sijhawm, LEDs feem ntau tseem khaws cov khoom tso tawm ntawm 70 feem pua ntawm qhov tseem ceeb ntawm qhov kawg ntawm lawv lub neej.
Yog tias koj tab tom nrhiav lub teeb pom kev ntev ntev, koj tuaj yeem xav txog LEDs. LEDs tau dhau los ua lub teeb pom kev zoo tshaj plaws thiab yog vim li cas. Yog tias koj npaj yuav pib, peb tshwj xeeb hauv kev muab cov teeb ci LED rau ntau daim ntawv thov. Koj tuaj yeem tshawb xyuas peb cov kev xaiv ntawm LED teeb ntawm no.
