Ib qho ntawm cov teeb pom kev zoo tshaj plaws ntawm kev ua lag luam yog LEDs, qee zaum hu ua "Light-Emitting Diodes." Nyob rau xyoo 1960, tus kws tshawb fawb Nick Holonyak Junior tau tsim cov khoom siv hluav taws xob, uas tau siv rau lub rooj tsav xwm hluav taws xob thiab cov khoom siv hluav taws xob me me.
Txij thaum ntawd los, LEDs tau txhim kho nyob rau hauv qhov ci, durability, thiab ntau yam. Tej zaum lawv yuav raug siv rau cov hom phiaj siv hluav taws xob hauv txhua qhov chaw lossis los txhim kho koj lub tsev décor. Sawb teeb yog hom nrov tshaj plaws ntawm txhua qhov sib txawv.
Koj puas xav tau lub teeb pom kev zoo rau koj chav pw uas tuaj yeem hloov xim? Yuav ua li cas yog tias yuav tsum tau teeb pom kev zoo hauv qab koj chav ua noj txee? Txhua qhov DIY project yuav tau txais txiaj ntsig los ntawm kev siv LED sawb teeb ua qhov siv tau zoo dua qhov teeb pom kev zoo.
Txawm li cas los xij, LED sawb teeb ua haujlwm ntev npaum li cas? Puas yog lawv tsim nyog rau kev siv nyiaj thiab kev siv zog? Niaj hnub no, Lub Teeb Khoom Muag yuav teb cov lus nug saum toj kawg nkaus hais txog LED sawb teeb.
Ntev npaum li cas LED sawb teeb?
LED sawb teeb feem ntau kav ntev li 50,000 teev nyob rau nruab nrab! Tab sis qhov no tsuas yog qhov nruab nrab kwv yees xwb. Raws li kev tsim khoom zoo thiab koj siv LEDs hauv koj lub tsev li cas, lawv yuav kav ntev heev.
Yog tias koj saib xyuas koj lub teeb sawb, koj tuaj yeem siv lawv tsis tu ncua rau li rau xyoo. Piv txwv li, koj yuav tsum ib txwm tua koj lub teeb ci LED thaum tsis siv kom tsis txhob nkim lub zog thiab ua kom lawv lub neej ntev.
Tsawg tus neeg tuaj yeem paub tias LEDs tau nkag siab rau qhov kub thiab txias. Thaum tshav kub kub los yog txias heev tuaj yeem ua rau lawv lub neej expectancy luv luv. Yog li ntawd, peb tau qhia kom tswj qhov ntsuas kub tsis tu ncua rau koj cov LEDs.
Puas yog LED teeb hluav taws kub?
LEDs tsis tawm sai sai thiab tso koj nyob rau hauv qhov tsaus ntuj li lub teeb incandescent ua.
Txawm li cas los xij, raws li lub sijhawm dhau mus, lawv txoj kev ci ntsa iab yuav maj mam txo qis. Cov filaments siv nyob rau hauv incandescent teeb pom kev zoo sai sai oxidize thiab hlawv tawm. LEDs tsis ua haujlwm tam sim ntawd thaum lawv lub hwj chim khiav tawm; Hloov chaw, lawv raug luminous lwj, uas ua rau koj lub teeb los ua dimmer heev.
L70 metric yog siv los ntawm kev lag luam teeb pom kev zoo los ntsuas lub neej ntawm LED sawb teeb; nws qhia koj tias nws yuav siv sijhawm ntev npaum li cas ua ntej koj lub teeb pib ploj mus. L70 metric, feem ntau hu ua lub sij hawm nws yuav siv sij hawm rau koj lub teeb kom emit 30 feem pua tsawg dua ntawm nws thawj luminosity, ntsuas lub teeb tso zis decay point.
Raws li ib qho piv txwv, lub teeb lub neej ntawm peb Lub Siab Bendable FLEXile IP44 LED Sawb Teeb pom kev zoo yog qhov zoo tshaj plaws ntawm 30, 000 teev.
Koj lub teeb sawb LED tseem yuav tsim 70 feem pua ntawm lawv qhov pib ci ntsa iab txawm tias tom qab peb thiab ib nrab xyoo ntawm kev siv txuas ntxiv! Ib qho ntawm qhov zoo nkauj tshaj plaws ntawm LED teeb yog lawv cov kav ntev. Tab sis ntau tus kuj muaj nuj nqis rau lawv rau lawv txoj kev siv zog.
LED sawb teeb kub npaum li cas?
Lub tshav kub tsim los ntawm LED sawb teeb yog txawv ntawm cov teeb ci thiab cov fluorescent. Lub teeb incandescent siv ib ncig ntawm 90 feem pua ntawm nws lub zog los ua kom sov. Qhov tseeb, lawv tsim kom muaj cua sov ntau heev uas lub teeb tuaj yeem tawg yog tias lawv khaws cia ntev dhau.
Lub zog efficiency ntawm lub teeb incandescent yog qhov qis dua li ntawm LED vim tias muaj zog ntau yog siv los ua cua sov. Ib qho LED tuaj yeem siv 'cov dab dej kub' los cuam tshuam cov cua sov rau hauv qhov chaw thaum nws tsim cov cua sov, tso cai rau nws tsom 80 feem pua ntawm nws lub zog ntawm kev tsim lub teeb thiab 20 feem pua ntawm kev tso cua sov.
Physics hais tias txhua yam uas tsim teeb pom kev siv hluav taws xob kuj yuav tsim hluav taws xob. Tab sis muaj qhov laj thawj zoo vim li cas LED sawb teeb yog tam sim no ntawm cov kev xaiv teeb pom kev zoo tshaj plaws. Lawv tsis tsuas yog pheej yig xwb tab sis kuj muaj zog heev!
