Raws li lub cim tshiab ntawm lub teeb ci, LED taw tes lub teeb ci tau txais cov teeb pom kev hauv LED txias, uas tuaj yeem tawm xim sib txawv raws li qhov xav tau;tib lub sijhawm, nws tseem tuaj yeem ua rau hauv microcomputer nti, los ntawm kev tswj hwm kev tswj hwm, kom ua tiav cov xim muaj xim zoo nkauj xws li cov yeeb yuj gradient, dhia, scan, thiab dej;Kuj Lub vijtsam zaub ntawm ib qho kev qhia tshwj xeeb tuaj yeem hloov pauv los ntawm array thiab cov duab ua ke ntawm ntau lub teeb pom kev pixels, thiab ntau yam qauv, ntawv nyeem thiab cov duab, cov teebmeem video, thiab lwm yam tuaj yeem hloov pauv;point light qhov chaw yog heev dav siv nyob rau hauv sab nraum zoov teeb pom kev zoo tej yaam num.
LED taw tes lub teeb qhov chaw muaj qhov sib txawv ntawm cov hluav taws xob hluav taws xob thiab cov hluav taws xob tso tawm hluav taws xob (xws li cov teeb incandescent, high-pressure sodium teeb).
Tam sim no LED point teeb qhov chaw muaj qhov zoo hauv qab no hauv kev teeb pom kev zoo:
1. zoo seismic thiab cuam tshuam tsis kam
Lub hauv paus qauv ntawm LED taw tes lub teeb qhov chaw yog muab cov khoom siv electroluminescent semiconductor rau ntawm cov hlau lead, thiab tom qab ntawd muab khi nrog epoxy resin nyob ib ncig ntawm nws.Tsis muaj iav plhaub hauv cov qauv.Tsis tas yuav nqus los yog sau cov roj tshwj xeeb hauv lub raj zoo li cov roj teeb lossis cov roj fluorescent.Yog li ntawd, LED lub teeb qhov chaw muaj kev poob siab zoo thiab kev cuam tshuam tsis zoo, uas coj kev yooj yim rau kev tsim khoom, kev thauj mus los thiab kev siv lub teeb ci LED.
2. muaj kev nyab xeeb thiab ruaj khov
LED taw tes teeb qhov chaw tuaj yeem tsav los ntawm qhov tsis tshua muaj hluav taws xob DC.Raws li ib txwm muaj, lub zog hluav taws xob hluav taws xob yog nyob nruab nrab ntawm 6 thiab 24 volts, thiab kev nyab xeeb kev ua haujlwm zoo dua.Nws yog qhov tshwj xeeb tshaj yog siv rau hauv cov chaw pej xeem.Tsis tas li ntawd, nyob rau hauv ib puag ncig zoo dua qub, lub teeb qhov chaw muaj lub teeb attenuation tsawg dua li cov teeb pom kev zoo ib txwm muaj thiab muaj lub neej ntev.Txawm hais tias nws nquag qhib thiab kaw, nws lub neej yuav tsis cuam tshuam.
3. kev ua haujlwm zoo ib puag ncig
Vim tias LED taw tes lub teeb ci tsis ntxiv cov hlau mercury thaum lub sijhawm tsim khoom, nws yuav tsis ua rau muaj kuab paug mercury tom qab muab pov tseg, thiab nws cov khoom pov tseg tuaj yeem rov ua dua tshiab, txuag cov peev txheej thiab tiv thaiv ib puag ncig.
4. lub sij hawm teb ceev ceev
Lub sij hawm teb ntawm lub teeb incandescent yog milliseconds, thiab lub sij hawm teb ntawm teeb pom kev zoo yog nanoseconds.Yog li ntawd, nws tau dav siv nyob rau hauv thaj chaw ntawm lub teeb tsheb thiab tsheb teeb.
5. zoo brightness kho
Raws li lub hauv paus ntsiab lus ntawm LED taw tes lub teeb qhov chaw, lub luminous brightness los yog tso zis flux yog zoo hloov los ntawm qhov pib tam sim no.Nws ua haujlwm tam sim no tuaj yeem loj lossis me me hauv qhov ntsuas qhov ntsuas, thiab muaj kev hloov kho tau zoo, uas ua rau lub hauv paus rau kev paub txog cov neeg siv khoom txaus siab teeb pom kev zoo thiab ci ntsa iab stepless tswj ntawm LED taw tes teeb qhov chaw.
