Dab tsi yog coj?
LED sawv rau "lub teeb emitting diode." Nws yog lub cuab yeej ua qauv zoo nkauj uas emits teeb thaum muaj hluav taws xob tam sim no hla nws. LEDs yog siv nyob rau hauv ntau cov ntawv thov, suav nrog kev teeb pom kev zoo, nthuav qhia, ntsuas, thiab lwm yam. Lawv paub txog lawv lub zog ua haujlwm, siv nyiaj ruaj khov, thiab lub neej ntev sib piv rau cov kev ua yeeb yam incandescent lossis fluorescent qhov muag teev. LEDs tuaj hauv ntau cov xim thiab tuaj yeem siv rau hauv cov khoom muaj ntau yam, los ntawm cov ntsuas hluav taws xob yooj yim rau cov khoom siv hluav taws xob yooj yim rau cov khoom siv hluav taws xob.
Lub hauv paus ntsiab lus ntawm LED teeb pom kev zoo
Thaum lub tshuab hluav taws xob thiab qhov sib tw ntawm lub teeb-emitting ntawm lub zog hluav taws xob, thiab cov hluav taws xob tso lub zog loj tshaj plaws hauv daim ntawv emitated photment (electromagnetic vuag (hluav taws xob hluav taws xob), ua rau electroluminescence. Cov xim ntawm lub ci ci yog cuam tshuam nrog cov khoom siv uas ua nws lub hauv paus. Lub ntsiab ntawm cov neeg ua haujlwm tseem ceeb xws li Gallium Arsenide Diode emicium carride lub teeb, thiab gallium nitride Diode pom lub teeb xiav.
Lub teeb pom kev sib piv
LED: Tsim Kev Nkag Siab Hloov Siab hloov siab (ze li 60%), muaj lub neej nyob ib puag ncig (txog li 3V), tsis muaj kev poob qis, me me loj, tsawg loj , siab brightness, muaj zog thiab ruaj, yooj yim rau kev, ntau yam xim, concentrable nqaj, tsis muaj kev ncua nyob rau hauv kev pib.
Incandescent teeb: Qes Electro-Option Electro-Option Electro-Optioneccess Efficiency (li 10000 teev (txog 1000 teev thiab kub thiab xim qis kub.
Cov roj fluorescent teeb cig: tsis tshua muaj hluav taws xob hloov kho efficiency (li 30%), tsis muaj kev phom sij tsis muaj teeb liab (cov hluav taws xob tsis tshua muaj teeb), ultraviolet hluav taws xob, flickering tshwm sim, maj mam pib qeeb, tus nqi ntawm lub ntiaj teb raw cov ntaub ntawv nce ntxiv, rov qab hloov cuam tshuam rau lub neej, thiab lub ntim yog Loj.High-siab roj tawm teeb lub zog: Siv ntau lub zog, tsis raug kev txom nyem, muaj cov teeb meem luv luv, thiab muaj cov teeb meem sov dissipation. Lawv feem ntau yog siv rau sab nraud teeb pom kev zoo.
Qhov zoo ntawm cov coj
LED yog cov nti me me encapsulated nyob rau epoxy cob, yog li nws yog me me thiab lub teeb ci. Feem ntau hais lus, Cov kev ua hauj lwm voltage ntawm LED yog 2-3.6V, kev ua haujlwm tam sim no yog 0.02-0.03a, thiab lub zog siv feem ntau tsis muaj ntau dua
0.1w. Nyob rau hauv ruaj khov thiab tsim nyog voltage thiab kev ua haujlwm tam sim no, kev pabcuam lub neej muaj peev xwm ntev li 100,000 teev.
LED siv txias lub cev nqaij txias tshuab, uas tsim kom muaj cua sov ntau dua li lub teeb pom kev zoo tib yam nkaus ntawm tib lub zog. LEDs yog ua los ntawm cov ntaub ntawv uas tsis muaj tshuaj lom, tsis zoo li cov roj ntsha fluorescent uas muaj mercury, uas tuaj yeem ua rau muaj kuab paug. Nyob rau tib lub sijhawm, LEDs kuj tseem tuaj yeem rov ua dua tshiab thiab rov siv dua.
Daim Ntawv Thov Led
Raws li LED tshuab txuas ntxiv kom paub tab thiab tsim kho sai, ntau dua thiab ntau dua LED cov ntawv thov tshwm sim hauv peb lub neej txhua hnub. LEDs yog dav siv nyob rau hauv LED cov teeb meem, lub teeb taws carrotive, teeb pom kev zoo nkauj, thiab lwm yam.
Kev tsim kho LED
LED yog lub teeb ci-emitting, bracket thiab cov xov hlau encapsulated hauv epoxy cob qhia. Nws yog lub teeb, tsis-toxic thiab muaj kev poob siab tsis kam. LED muaj ib txoj kev conduction zoo, thiab thaum rov qab voltage yog dhau lawm, nws yuav ua rau muaj kev sib txig. Cov qauv tseem ceeb muaj nyob hauv daim duab:
