Vim li cas LED chaw ntau pob teeb yog qhov kev xaiv zoo tshaj plaws
Thaum xaiv cov teeb pom kev hauv chaw ntau pob los nruab rau hauv chaw ntau pob, tsis txhob tsom mus rau cov kev daws teeb meem luv luv rau cov teeb meem ntawm teeb pom kev zoo. Nws lub hom phiaj yuav tsum yog txhawm rau txhim kho qhov zoo ntawm cov chaw yav tom ntej, nrog rau kom ntseeg tau tias cov nqi kho mob ib txwm nyob hauv pob nyiaj siv.
Piv nrog cov hlau halide kev ua si teeb, LED kev ua si teeb muaj qhov zoo dua
Ob lub hom phiaj tuaj yeem ua tiav nrog Hishine Stadium teeb. Yog li ntawd, xaiv txoj cai LED kev ua si teeb rau koj lub chaw ntau pob yog qhov tseem ceeb heev rau txoj kev npaj ua lag luam ua tiav.
Vim li cas kuv thiaj yuav tsum xaiv LED teeb hla lub teeb halogen?
Yuav kom nkag siab tias lub teeb tsim li cas, nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem teeb pom kev zoo ntawm ob lub teeb. Thawj qhov tshwm sim ua ntej hluav taws xob mus txog lub teeb LED thiab tuaj yeem suav tias yog kev siv hluav taws xob. Qhov thib ob tshwm sim me ntsis tom qab, los ntawm qhov projection ntawm lub teeb.
A. Cov txheej txheem siv hluav taws xob
Los ntawm kev siv hluav taws xob peb txhais tau tias feem pua ntawm lub zog siv, uas yog qhov tseem ceeb rau kev tig lub teeb. Hauv ib lub teeb halogen ib txwm, txog li 80 feem pua ntawm lub zog yog nkim hauv cov txheej txheem tsim hluav taws xob. Siv peb cov LEDS, lub zog khib nyiab tsawg dua 10 feem pua, yog li peb cov kev ua si LED teeb pom kev zoo yuav xav tau lub zog tsawg dua thiab yuav ua tiav qhov ci tshaj qhov uas muab los ntawm halogen teeb pom kev zoo.
B. Lub teeb projection txheej txheem
Cov txheej txheem teeb pom kev zoo yog theem ob. Thaum lub teeb ci tau qhib, koj yuav tsum tau ua kom pom lub teeb ntawm kev siv zog rau hauv av. Qhov no yog qhov sib txawv ntawm luminosity thiab efficiency yog qhov tseem ceeb heev.
Puas yog lub zog LEDs muaj zog dua vim tias lawv ci ntsa iab?
Lo lus teb rau lo lus nug no yooj yim: tsis yog. Rau cov teeb ci LED, qhov tseem ceeb tshaj plaws tsis yog qhov ci ntsa iab, tab sis deb npaum li cas lawv tuaj yeem ua lawv qhov ci. Yog hais tias lub teeb ci heev rau thawj 5-10 meters tab sis taper tawm tom qab qhov kev ncua deb, ces lub teeb ncav cuag lub suab yuav qis heev, uas yuav tsum tau coj mus rau hauv tus account tias rau kev ua kis las teeb pom kev zoo feem ntau yog ntsia rau ntawm cov ncej siab. .
Yog li peb yuav tsum xav txog tsis yog tsuas yog luminosity xwb, tab sis kuj yuav ua li cas lub teeb mus dhau qhov deb. Luminosity yog ib qho tseem ceeb, tab sis tsis yog tib qho los xav txog.
Lub peev xwm mus ncig no ua tiav li cas?
Cov ntsiab lus tseem ceeb uas ua kom muaj teeb pom kev siab yog lub hom phiaj tseem ceeb ntawm kev txav LED teeb pom kev zoo. Geometric optics, uas kho lub teeb raws li cov kab ncaj nraim uas khoov thaum hla los yog cuam tshuam ntawm qhov chaw.
Yog li ntawd, thaum tsim thiab txhim kho txhua lub lens siv rau qhov chaw ua si teeb pom kev zoo, nws yog ib qho tseem ceeb kom ua kom pom qhov kev tsom xam ntawm qhov teeb pom kev zoo li cas thiab ua haujlwm rau hauv ib qho kev taw qhia hauv ib txoj kev. Qhov no ua tiav los ntawm kev ua lej ua ke thiab cov txheej txheem ntawm lub teeb simulation. Tag nrho cov no peb (LED cov kws paub txog teeb pom kev zoo) ua tau zoo tshaj plaws, ua tsaug rau peb cov kws tshaj lij engineering department. Yog tias cov leds muaj ntau dua, lub teeb tsawg dua yuav tawg los yog nkim thaum koj txav mus deb ntawm qhov khoom siv.
