LED teeb pom kev kub ntxhov yog ib yam khoom tseem ceeb rau txhua tsev neeg lossis chaw ua haujlwm. Lawv muab lub teeb pom kev zoo thaum muaj hluav taws xob lossis lwm yam xwm txheej kub ntxhov, ua kom peb tuaj yeem pom thiab nyob nyab xeeb ntxiv. Tab sis cov teeb no ua haujlwm li cas?
Ua ntej, nws yog ib qho tseem ceeb kom nkag siab tias LEDs ua haujlwm li cas. LEDs, los yog Lub Teeb Emitting Diodes, yog cov khoom siv hluav taws xob uas hloov hluav taws xob rau hauv lub teeb. Tsis zoo li cov teeb pom kev zoo ib txwm muaj, uas muaj lub teeb ci uas tawm teeb pom kev thaum cua sov los ntawm hluav taws xob tam sim no, LED qhov muag teeb tawm lub teeb los ntawm cov txheej txheem hu ua electroluminescence. Thaum ib tug tam sim no siv rau ib tug LED nti, electrons zoo siab thiab emit photons, los yog me me pob ntawv ntawm lub teeb.
Tam sim no, cia peb saib seb qhov teeb pom kev kub ceev LED ua haujlwm li cas. Feem ntau, cov qij no muaj ib lub roj teeb uas yog recharged thaum lub teeb yog screwed rau hauv lub qhov (socket) qauv. Thaum lub hwj chim tawm, lub teeb yuav hloov mus rau hom roj teeb thiab muab lub teeb rau lub sijhawm teem sijhawm, feem ntau yog ob peb teev.
Muaj ob hom kev kub ceev LED qhov muag teev: tsis tu thiab khaws cia. Cov qhov muag tsis tu ncua yog tsim los tsuas yog teeb pom kev thaum muaj hluav taws xob hluav taws xob, thaum lub qhov muag teev tuaj yeem ua haujlwm zoo li ob qho tib si teeb pom kev zoo thiab xwm txheej ceev.
Nyob rau hauv ib lub teeb uas tsis tau khaws cia, lub roj teeb tseem nyob twj ywm kom txog thaum lub hwj chim tawm. Thaum qhov no tshwm sim, lub teeb siv lub tshuab hluav taws xob qis kom txuag hluav taws xob thaum tseem muab lub teeb txaus los mus rau qhov chaw. Nyob rau hauv ib lub qhov muag teev, lub roj teeb yog nyob rau hauv kev siv tas li thiab yog recharged thaum lub hwj chim qhib. Qhov no tso cai rau lub teeb ua haujlwm raws li ob qho tib si ib txwm muaj thiab teeb pom kev kub ceev thiab xyuas kom meej tias lub roj teeb yeej ib txwm them thiab npaj mus.
Cov teeb pom kev kub ceev LED kuj feem ntau muaj cov yam ntxwv ua kom lawv ua haujlwm zoo dua thaum muaj xwm txheej ceev. Piv txwv li, qee lub qhov muag teev muaj qhov ntsuas tus kheej uas tau kuaj xyuas lub roj teeb thiab cov khoom siv hluav taws xob tsis tu ncua kom ntseeg tau tias lawv ua haujlwm zoo. Lwm tus yuav muaj lub suab sensors lossis cov chaw taws teeb tswj kev muaj peev xwm ntxiv rau kev yooj yim thiab kev nyab xeeb.
Zuag qhia tag nrho, LED qhov muag teeb thaum muaj xwm txheej ceev yog ib txoj hauv kev txhim khu kev qha thiab zoo los xyuas kom meej tias koj muaj teeb pom kev zoo thaum muaj hluav taws xob hluav taws xob lossis lwm yam xwm txheej ceev. Los ntawm kev nkag siab tias lawv ua haujlwm li cas, koj tuaj yeem txiav txim siab seb hom teeb twg yog qhov zoo rau koj cov kev xav tau thiab ua cov kauj ruam los xyuas kom meej tias koj thiab koj cov neeg koj hlub tau npaj rau txhua qhov xwm txheej.
