Lub teeb diodes yog cov khoom siv hluav taws xob qis hluav taws xob uas tawm lub teeb thaum cov hluav taws xob hla dhau ntawm qhov kev sib tshuam p-n. Lub teeb emission tshwm sim thaum cov khoom me me raug txhaj los ntawm p-n hlws ris. Diodes tuaj yeem zoo siab los ntawm kev ncaj qha, hloov pauv thiab lub zog hluav taws xob.
Ib lub teeb diode muaj anode thiab cathode. Lub anode yog tsim los nyiam electrons uas tawm los ntawm cathode, ib qho zoo voltage yog ib txwm siv rau lub anode. Thaum cov hluav taws xob tam sim no raug siv rau cov kev sib cuag ntawm lub teeb ntawm lub anode thiab cathode, ib qho hluav taws xob hluav taws xob tau tsim, nws pab cov electrons uas tau ntws tawm ntawm lub cathode (xws li electrons hu ua dawb) txav mus rau lub anode. Tam sim no, LED teeb yog qhov kev cia siab tshaj plaws hauv kev txhim kho cov cuab yeej teeb pom kev zoo thiab cov teeb pom kev zoo. Diode teeb hloov lub teeb thiab halogen teeb, lawv pib sib tw txawm tias txuag hluav taws xob.
Diode teeb muaj nws qhov zoo thiab qhov tsis zoo. Nws lub ntsiab kom zoo dua yog tsawg zog noj. Nws yog kwv yees li kaum npaug qis dua li ntawm lub teeb incandescent, thiab li peb zaug qis dua li ntawm lub teeb fluorescent. noj me mehluav taws xob tam sim no vim lub fact tias lub hwj chim ntawm diode teeb yog heev tsawg.
Qhov thib ob kom zoo dua yog lub neej ua haujlwm ntev - 100,000 teev, lossis 11 xyoo ua haujlwm tas li. Qhov txiaj ntsig tom ntej: lub teeb diode yog qhov tsis muaj teeb meem, tsis muaj mercury thiab yooj yim pov tseg. Vim lub fact tias diode teeb xyaum tsis ua kom sov thaum lub sij hawm ua hauj lwm, lawv raug suav hais tias fireproof, yog li ntawd lawv yuav siv tau nyob rau hauv cov chaw uas tsis zoo cua, xws li cov ceilings cuav. Qhov kom zoo dua ntawm cov cuab yeej yog lawv lub zog siv tshuab siab, lawv tsis ntshai txawm tias poob ntawm qhov siab, thiab tag nrho cov no yog vim cov ntaub ntawv uas lawv tau tsim.
Muaj qhov tsis zoo rau LED teeb ntau dua qhov zoo. Lub ntsiab tsis zoo yog tus nqi siab heev. Piv txwv li, tsev neeg diode teeb nrog lub zog ntawm 9-10 W yuav raug nqi txog 2,000 rubles, thiab ib qho chaw ua haujlwm (Armstrong qab nthab) - los ntawm 5,000 rubles. Qhov thib ob qhov tsis zoo: 100,000 teev ntawm kev ua haujlwm tas li tshaj tawm los ntawm cov tuam ntxhab hauv kev xyaum qhia lub neej luv dua. Qhov no yog vim muaj cov nyhuv degradation ntawm LED crystals. Cov chaw tsim khoom muab kev lees paub rau nws cov khoom rau 3-5 xyoos. Xav tias lub teeb diode them tawm hauv 5 xyoos, koj tuaj yeem poob koj cov nyiaj. Qhov teeb meem tom ntej no yog lub teeb pom kev nqaim thiab tsis kaj siab spectrum.
LED teeb tau pom lawv daim ntawv thov hauv kev lag luam tsheb. Txij li thaum xyoo 1990, automakers tau pib siv LEDs hauvtsheb lub teeb, nres teeb, taw qhia, qhov ntev, sab hauv thiab ntsuas vaj huam sib luag teeb pom kev zoo, thiab lwm yam. Diode teeb rau lub tsheb muaj qhov sib txawv ntawm luminescence: los ntawm liab mus rau xiav. Tam sim no ntau lub tuam txhab tsim cov LEDs zoo rau lub tsheb ntawm cov qauv sib txawv, qhov no qhib lub sijhawm loj rau kev kho tsheb.
