Yuav Ua Li Cas Led Sawb Teeb Ua Haujlwm

LED Sawb teeb ua haujlwm li cas?

LED sawb teeb tau dhau los ua ib feem tseem ceeb ntawm cov teeb pom kev zoo niaj hnub no thiab siv ntau yam kev siv, suav nrog teeb pom kev sab hauv, teeb pom kev zoo nkauj, thiab txawm nyob hauv cov khoom siv hluav taws xob. LED sawb teeb yog nyiam dua li cov teeb pom kev lag luam qub vim tias lawv muaj lub zog txuag thiab muaj lub neej ntev dua. Tab sis lawv ua haujlwm li cas? Cia peb tshawb nrhiav.

Dab tsi yog LED Sawb Teeb?

LED sawb teeb yog tsim los ntawm ib tus neeg LED teeb teeb tsa hauv ib ntu thiab txuas rau ntawm lub rooj tsav xwm hloov pauv tau. Lub rooj tsav xwm Circuit Court feem ntau muaj cov nplaum nplaum rau sab nraub qaum, ua rau nws yooj yim rau nruab. LED sawb teeb tuaj nyob rau hauv ntau qhov ntev, xim, thiab qib ci ci, ua rau lawv muaj ntau yam rau ntau yam kev xav tau teeb pom kev zoo.

Dab tsi ua rau LED Sawb Teeb Ua Haujlwm?

LED sawb teeb ua haujlwm raws li lub hauv paus ntsiab lus ntawm electroluminescence. Electroluminescence yog ib qho tshwm sim uas lub teeb tawm ntawm cov khoom thaum raug hluav taws xob. LEDs yog tsim los ntawm cov khoom siv semiconductor, feem ntau yog gallium arsenide, uas tso tawm lub zog nyob rau hauv daim ntawv ntawm lub teeb thaum raug hluav taws xob tam sim no.

Yuav ua li cas LED sawb teeb tsim xim?

LED sawb teeb tuaj yeem tsim cov xim sib txawv los ntawm cov txheej txheem hu ua xim sib xyaw. Kev sib xyaw xim sib xyaw nrog cov xim sib txawv los tsim cov xim uas xav tau. LED sawb teeb tuaj yeem tsim cov xim sib txawv los ntawm kev siv RGB lossis RGBW LEDs.

RGB LEDs muaj peb xim, liab, ntsuab, thiab xiav, uas, thaum sib xyaw ua ke sib txawv, tuaj yeem tsim yuav luag txhua xim. RGBW LEDs, ntawm qhov tod tes, muaj Liab, Ntsuab, Xiav, thiab Dawb LEDs, uas tuaj yeem tsim cov xim ntshiab thiab ci dua. RGBW LED sawb teeb yog nyiam rau cov ntawv thov ntau dua li kev yees duab thiab yees duab.

Yuav Ua Li Cas LED Sawb Teeb Ua Lub Teeb?

LED sawb teeb tsim lub teeb los ntawm emission ntawm photons. Thaum ib tug tam sim no ntws los ntawm ib tug LED sawb teeb, nws excites lub electrons nyob rau hauv cov khoom semiconductor, ua rau lawv tso tawm lub zog nyob rau hauv daim ntawv ntawm photons. Cov photons tom qab ntawd tsim lub teeb uas pom tau rau tib neeg lub qhov muag.

Yuav ua li cas LED sawb teeb ua tiav qhov sib txawv Brightness?

LED sawb teeb muaj qhov sib txawv ntawm qhov ci ntsa iab uas tuaj yeem ua tiav los ntawm qhov sib txawv ntawm qhov lawv tau txais tam sim no. Lub ci ci ntawm LED sawb teeb yog ntsuas hauv lumens. Qhov ntau lumens LED sawb teeb muaj, qhov ci dua.

LED sawb teeb tseem muaj qhov tshwj xeeb hu ua Pulse-width modulation (PWM) uas tso cai rau kev tswj qhov ci. PWM yog ib txoj hauv kev hloov pauv lub zog xa mus rau LED los ntawm kev tig lub LED sai sai. Los ntawm kev hloov kho sai ntawm LED lub sijhawm, PWM tuaj yeem hloov lub teeb pom kev ci ntsa iab tsis cuam tshuam rau nws cov xim.

Yuav Ua Li Cas LED Sawb Teeb Sib Piv rau Lwm Cov Teeb Pom Kev Zoo?

LED sawb teeb muaj lub zog ntau dua thiab muaj lub neej ntev dua piv rau lwm yam kev siv teeb pom kev zoo xws li cov qij incandescent thiab teeb fluorescent. LED sawb teeb siv tsawg zog vim lawv hloov ntau lub zog rau hauv lub teeb. Qhov no txhais tau tias lawv tsim hluav taws xob tsawg dua thiab muaj cov nqi hluav taws xob qis dua.

LED sawb teeb kuj tseem muaj zog dua piv rau lwm yam khoom siv teeb pom kev zoo vim tias lawv muaj cov qauv tsim muaj zog. Lawv tsis tshua muaj kev puas tsuaj thiab tsis cuam tshuam los ntawm kev vibrations, ua rau lawv zoo tagnrho rau siv hauv tsheb thiab nkoj.

Xaus

LED sawb teeb yog ntau yam teeb pom kev zoo teeb pom kev zoo uas muaj lub zog ua haujlwm, ua haujlwm ntev, thiab yoog raws. Lawv siv lub hauv paus ntsiab lus ntawm electroluminescence los tsim lub teeb, thiab xim sib tov los tsim cov xim sib txawv. Lawv qhov ci ntsa iab tuaj yeem hloov kho siv PWM, thiab lawv muab piv rau lwm yam teeb pom kev zoo. LED sawb teeb yog ib qho kev xaiv zoo rau sab hauv teeb pom kev zoo, teeb pom kev zoo, thiab txawm nyob hauv cov khoom siv hluav taws xob.
