Nyob rau hauv lub ntiaj teb no lub zog nruj zuj zus, nws yog lub luag haujlwm rau peb txhua tus kom txuag tau lub zog. Nyob rau hauv kev teb rau kev hu rau kev txuag hluav taws xob thiab txo qis emissions, ntau txoj kev teeb manufacturers tau hloov cov tsoos high-pressure sodium teeb nrog ntau lub zog-npaum siab zog 200w sab nraum zoov slim coj dej nyab teeb teeb nyob rau hauv nroog txoj kev teeb renovation tej yaam num. Txawm li cas los xij, theem zoo tam sim no ntawm LED txoj kev teeb nyob rau hauv kev ua lag luam tsis sib xws, thiab LED txoj kev teeb nyob rau hauv ntau qhov chaw yuav tsis kaj. Tom qab tag nrho, vim li cas rau qhov tshwm sim no yog qhov tsis zoo ntawm cov hluav taws kub dissipation ntawm LED txoj kev teeb. Thaum tshav kub dissipation kev ua tau zoo tsis zoo, qhov kub thiab txias ntawm LED teeb yuav siab dhau. Thaum qhov kub ntawm LED nce, nws qhov kev sib tshuam tsis kam txo, ua rau txo qis ntawm qhov hluav taws xob. Nyob rau hauv tib lub voltage, qhov kub thiab txias ntawm LED teeb yuav ua rau LED tam sim no nce. Kev nce tam sim no yuav nce qhov kub thiab txias, uas yuav ua rau lub voj voog tsis zoo los hlawv LED nti. Ntxiv mus, qhov kub thiab txias ntawm LED txoj kev teeb fixture yog siab dhau lawm, uas tseem ua rau LED nti lub teeb attenuation zuj zus, yog li ntawd nws yuav sai sai ua rau lub phenomenon ntawm tsis muaj teeb. Yog li dab tsi ua rau qhov tsis zoo ntawm cov hluav taws kub dissipation ntawm LED txoj kev teeb?
Ua ntej, qhov zoo ntawm LED txoj kev teeb
Cov chip LED saws muaj cov thermal conductivity tsis zoo, thiab qhov kub thiab txias ntawm LED tsis tuaj yeem xa mus rau qhov chaw (sab hauv tshav kub thiab qhov txias txias). Txawm hais tias lub dab dej kub ntxiv, cov cua sov sab hauv tsis tuaj yeem ploj mus, thiab tom qab ntawd tsis muaj dab tsi kub hauv ib co LED txoj kev teeb ...
Qhov thib ob, qhov kub nce siab tshwm sim los ntawm LED txoj kev teeb lub zog hluav taws xob
Qhov zoo ntawm LED txoj kev teeb fais fab mov tsis zoo. Thaum lub LED yog nyob rau, qhov tsis-linearity ntawm lub hwj chim mov thiab tsis muaj zog hloov nyob rau hauv lub hwj chim mov yuav ua rau cov tam sim no los ntawm LED nti nce, uas yuav ua rau lub sab hauv kub siab dhau heev lawm thiab cuam tshuam lub tshav kub dissipation kev ua tau zoo. LED txoj kev teeb.
Hauv cov ntsiab lus, qhov laj thawj tseem ceeb rau kev ua haujlwm tsis zoo ntawm cov cua sov dissipation ntawm LED txoj kev teeb yog qhov zoo ntawm LED nti thiab lub zog tsav. Yog li ntawd, rau peb cov neeg yuav khoom, thaum yuav LED txoj kev teeb, peb yuav tsum tau hais txog nrog cov tuam txhab teeb pom kev zoo kom xaiv cov khoom siv zoo LED thiab cov khoom siv hluav taws xob, thiab tsis yog pheej yig. Tom qab tag nrho, cov khoom zoo yog twv yuav raug hu tsis pheej yig. Muaj teeb meem.
