Cov nyhuv ntawm Infrared LED Teeb hlaws ntawm LED Zaub

Qhov cuam tshuam ntawm infrared LED teeb hlaws ntawm LED zaub 1. Saib lub kaum sab xis: Qhov kev xav ntawm LED zaub txiav txim siab qhov kev xav ntawm infrared LED teeb hlaws. Tam sim no, feem ntau sab nraum zoov cov ntxaij vab tshaus siv kab rov tav foundations 100 °; Vertical foundations 50 °; Lub ellipse LED, sab hauv zaub screen yog 120 ntsug °; Patch LED. Zaub ntawm txoj kev loj feem ntau xaiv los ntawm 30 vim nws qhov tshwj xeeb °Lub round LED ntawm qhov pom yog txaus. Cov zaub ntawm cov tsev siab siab yuav tsum muaj kev xav ntsug siab. Txoj kev xav thiab ci ntsa iab yog qhov tsis sib xws, thiab qhov kev pom loj yuav inevitably txo qhov ci. Kev xaiv qhov kev xav yuav tsum tau txiav txim siab raws li lub hom phiaj tshwj xeeb. 2. Brightness: LED ci ci yog qhov tseem ceeb txiav txim siab hauv qhov ci ntawm lub vijtsam. Qhov siab dua qhov ci ntsa iab ntawm LED, qhov sib npaug ntawm kev siv tam sim no ntau dua, uas yog qhov zoo rau kev txuag hluav taws xob thiab tswj LED ruaj khov. LED muaj lub kaum sab xis sib txawv. Nrog lub ci ci ntawm lub nti, lub kaum sab xis me dua, lub teeb ci dua LED, tab sis qhov me dua qhov pom lub kaum sab xis ntawm lub vijtsam. Feem ntau, 100-degree LED yuav tsum raug xaiv los xyuas kom meej tias lub vijtsam zaub txaus. Rau qhov sib txawv ntawm qhov sib txawv thiab qhov pom kev sib txawv, qhov ntsuas qhov sib npaug yuav tsum pom nyob rau hauv qhov ci, lub kaum ntse ntse thiab tus nqi. 3. Ib qho kev ua tau zoo: Txij li cov xim puv xim yog tsim los ntawm kaum tawm txhiab lossis txawm ntau pua txhiab pawg ntawm liab, ntsuab, thiab xiav, cov pixels yog tsim los ntawm pixels. Qhov tsis ua tiav ntawm ib qho xim LED yuav cuam tshuam rau tag nrho qhov pom ntawm qhov screen. Feem ntau hais lus, raws li kev lag luam kev paub, kev ua haujlwm tsis zoo ua ntej LED zaub pib sib sau ua ke rau 72 teev ntawm cov khoom xa tuaj yuav tsum tsawg dua 3% (hais txog qhov ua tsis tiav los ntawm infrared LED teeb hlaws nws tus kheej). Yuav kom nkag siab txog lub teeb ntawm infrared LED teeb hlaws, ua ntej ntawm tag nrho cov, peb yuav tsum to taub tias (i) yog lub tswv yim ntawm lub cev, chav tsev yog CD. Tus nqi ntawm lub teeb emitting siv qhia tau hais tias lub agglomeration ntawm lub emitting lub cev nyob rau hauv qhov chaw. Nyob rau hauv cov ntaub ntawv yooj yim, nws yog los piav txog ntau npaum li cas lub teeb qhov chaw “Ci ntsa iab ”Essence Qhov kev ua tau zoo ntawm niaj hnub infrared LED teeb hlaws feem ntau ntsuas qhov ci ntsa iab. Piv txwv li, ib qho infrared LED teeb hlaws yog 15000mcd, 1000mcd = 1cd, uas yog 15CD. Lub ci ci ntawm LEDs yog siv los ntawm MCD es tsis txhob CD ncaj qha vim hais tias lub teeb infrared thaum ntxov LED hlaws muaj qhov luminescence tsawg thiab qhov ci ntsa iab yog tsaus dua li lub teeb pom kev zoo. Siv lub teeb pom kev zoo los qhia txog infrared LED teeb hlaws “qhov kaj ”Txawm hais tias nws yog lub hom phiaj, kuj muaj qhov tsis xws luag. Piv txwv li, ob lub teeb infrared LED hlaws dai nrog cov nqi zoo tib yam muaj qhov ci ntsa iab. Yog li ntawd, cov neeg siv khoom yuav tsum tsis yog tsuas yog them sai sai rau lub teeb tus nqi thaum tau txais infrared LED teeb hlaws, tab sis kuj xyuam xim rau kev sib piv cov ntsiab lus pom. Nyob rau tib lub sijhawm, qhov kev daws teeb meem me dua, qhov siab dua qhov ci ntsa iab hauv chav tsev. Txwv tsis pub, txwv tsis pub. Tsis tas li ntawd, muaj lwm qhov parameter ntawm infrared LED teeb hlaws teeb pom kev zoo: lub teeb flux ntawm infrared LED teeb hlaws (F), chav tsev yog LM, thiab peb feem ntau siv cov lumens hauv Suav. Lub teeb ntsuas. Rau lub teeb ci, qhov ntsuas no yog qhov nthuav dav loj uas qhia txog tag nrho cov teeb pom kev zoo. Nws yog sib npaug rau lub zog kho qhov muag. Qhov loj dua qhov optical flux ntawm lub teeb qhov chaw, lub teeb ntau tshaj tawm lub teeb thiab lub zog ntawm qhov ci. Hais txog lub teeb infrared LED hlaws hlaws ntawm tib poj niam txiv neej (lub teeb ntawm lub teeb pom kev zoo tau nthuav tawm hauv txhua qhov kev qhia hauv txhua qhov kev qhia), F = 4 πI. Qhov ntawd yog hais tias, yog tias kuv ntawm lub teeb ci yog 1cd, tag nrho lub teeb flux yog 4 πLM. Yog tias koj xav kom ci dua, peb tsis tsuas yog yuav tsum txhim kho lub teeb flux, tab sis kuj nce qib ntawm agglomeration. Qhov tseeb, nws yog los txo qhov ci ntsa iab, kom peb tau txais kev siv zog ntau dua.
