LED sawb teeb tau dhau los ua neeg nyiam nyob rau xyoo tas los no vim lawv qhov ntau yam, lub zog ua haujlwm, thiab siv tau yooj yim. Cov teeb no yog tsim los ntawm ntau lub teeb-emitting diodes (LEDs) uas tau teeb tsa rau ntawm lub rooj tsav xwm hloov tau yooj yim.
Yog li cas LED sawb teeb ua haujlwm li cas? Nws tag nrho los ntawm txoj kev LEDs tau tsim thiab txuas nrog. Thaum hluav taws xob ntws los ntawm LED, nws hloov lub zog mus rau hauv lub teeb los ntawm cov txheej txheem hu ua electroluminescence.
Txhua LED tsim cov xim tshwj xeeb ntawm lub teeb nyob ntawm seb cov khoom siv semiconductor siv los ua nws. Piv txwv li, xiav LEDs yog ua los ntawm gallium nitride, thaum liab LEDs yog ua los ntawm txhuas gallium arsenide.
LED sawb teeb tuaj yeem yog xim ib leeg lossis ntau xim (RGB), thiab lawv tuaj yeem tswj tau siv cov chaw taws teeb lossis lub xov tooj ntawm tes. RGB LED strips muaj peb xim sib txawv LEDs (liab, ntsuab, thiab xiav) nyob rau hauv txhua seem uas tuaj yeem tswj tau tus kheej kom tsim tau ntau yam xim.
Lub kaw lus tswj tau siv rau LED sawb teeb yog los ntawm cov keyboards yooj yim mus rau ntau lub tshuab nrog wifi thiab Bluetooth txuas. Cov tswj hwm feem ntau siv cov mem tes dav dav (PWM), uas hloov lub luag haujlwm lub voj voog ntawm lub zog muab rau LEDs los tswj lawv qhov ci.
Lwm qhov tseem ceeb ntawm LED sawb teeb yog lawv cov khoom siv hluav taws xob. Cov teeb no yuav tsum muaj qhov tsis tshua muaj hluav taws xob DC fais fab, feem ntau 12 lossis 24 volts. Lub hwj chim mov yog lub luag hauj lwm rau hloov AC lub hwj chim los ntawm phab ntsa qhov hluav taws xob mus rau DC lub zog yuav tsum tau los ntawm LED sawb teeb.
Nyob rau hauv cov nqe lus ntawm installation, LED sawb teeb yog yooj yim heev rau teeb. Lawv tuaj nrog daim kab xev nplaum nyob tom qab uas tuaj yeem daig rau txhua qhov chaw du. Txiav thiab txuas cov ntu ntawm lub teeb sawb kuj yog qhov yooj yim, vim lawv tuaj yeem txiav ntawm cov ntu ntu thiab sib txuas ua ke kom haum txhua qhov ntev.
Hauv cov ntsiab lus, LED sawb teeb ua haujlwm los ntawm kev siv electroluminescence los hloov hluav taws xob hluav taws xob rau hauv lub teeb pom kev. Lawv yog tsim los ntawm ntau lub LEDs mounted ntawm lub rooj tsavxwm hloov tau yooj yim uas tuaj yeem tsim cov xim sib txawv thiab qhov ci ci. Lub kaw lus tswj thiab lub hwj huam mov yog cov khoom tseem ceeb uas tso cai rau kev hloov kho thiab yooj yim ntawm kev siv. Nrog lawv cov kev ua tau zoo thiab kev siv zog, LED sawb teeb yog qhov zoo ntxiv rau txhua lub tsev lossis kev lag luam.
