Yog vim li cas lub teeb Emitting Diode Darker thiab Darker

Txhua tus muaj lub neej zoo li no. Lub teeb LED nyuam qhuav yuav yog ib txwm ci tshwj xeeb, tab sis tom qab lub sijhawm, ntau lub teeb yuav tsaus thiab tsaus. Vim li cas LED teeb muaj cov txheej txheem zoo li no? Yuav kom nkag siab tias yog vim li cas koj lub teeb LED yuav tsaus dua thiab tsaus dua, peb yuav tsum xub nkag siab txog cov lus tshaj lij —— LED teeb hlaws dai tau poob qis. Tom qab lub diode ntawm lub raj, lub teeb lwj hais txog tias tom qab lub sijhawm teeb pom kev zoo, lub teeb lub zog piv yuav raug txo qis thiab tsis tuaj yeem rov qab tau, uas yog, qhov txo qis yog hu ua lub teeb lwj ntawm LED teeb hlaws. Qhov tsaus nti LED teeb yog siv vim tias LED teeb hlaws yuav muaj lub teeb lwj. Lub teeb lwj ntawm LED teeb cov khoom lag luam yog qhov tsis muaj zog ntawm cov teeb liab ntawm lub teeb hauv kev sib kis, thiab nyob rau theem no, lub ntiaj teb lub teeb-emitting diode cov tuam txhab loj ua rau cov teeb pom kev sib txawv ntawm lub teeb tawg, thiab lub teeb pom kev zoo ntawm lub teeb emitting diode kuj muaj teeb pom kev zoo. lwj. Kev sib raug zoo yog txiav txim siab los ntawm nti, fluorescent hmoov thiab ntim tshuab. Tam sim no, lub teeb tawg ntawm cov hlaws dawb ntawm lub lag luam yog ib qho teeb meem tseem ceeb rau kev taug kev mus rau pej xeem teeb pom kev zoo. Lub teeb lwj feem ntau yog hais txog nws lub teeb flux. Thaum them nyiaj rau saum npoo ntawm lub teeb nruas, raws li cov nqi tau sau rau ntawm qhov chaw ntawm lub teeb rhiab nruas, lub peev xwm tseem nce ntxiv. “saturation ”Qhov peev xwm yog qhov muaj peev xwm tshaj plaws. Lub peev xwm saum npoo yuav txo qis thaum lub sijhawm. Feem ntau, lub peev xwm ntawm lub sijhawm ua haujlwm yog qis dua li qhov muaj peev xwm no. Qhov peev xwm no raug txo qis thaum lub sijhawm. “Tsaus lwj ”Tsheb. Thaum lub sij hawm raug lub teeb nruas scanning, lub peev xwm ntawm qhov tsaus ntuj nti cheeb tsam (xa mus rau qhov chaw ntawm lub optical conductor uas tsis tau illuminated los ntawm lub teeb) yog tseem nyob rau hauv lub maub decay txheej txheem; Tus nqi conductivity tau nce sai, tsim kho qhov muag qhia qhov hluav taws xob, tus nqi ploj mus sai, thiab lub peev xwm ntawm tus neeg xyuas pib kuj poob sai. Hu rau “Lub teeb tsis ua haujlwm ”Essence no nyob ntawm no hnub no.
