Cov ntsiab lus ntawm Illuminance Meters, Kev Ua Haujlwm, thiab Kev Ua Haujlwm
Lub tshuab luam ntawv tsis siv neeg fiber ntau optic lux meter yog qhov ntsuas qhov muag siv los ntsuas qhov siv ntawm cov khoom siv dag zog thiab lub teeb ntuj. Nws daws qhov teeb meem ntawm kev ntsuas tsis tu ncua ntawm lub teeb siv thiab tsis siv neeg kaw. Nws muaj lub teeb pom kev zoo, lub tshuab hluav taws xob hloov pauv tsis siv neeg, lub kaw lus nkhaus, lub tshuab luam ntawv digital, thiab cov khoom siv tam sim no digital. Lub nkhaus kaw cov cuab yeej siv cov txheej txheem fiber ntau optic frictionless kaw, thiab lub teeb pom kev yog tsim los ntawm cov lim thiab xiav silicon photovoltaic cell, kom pom cov spectrum teb nkhaus ua raws li tib neeg kev pom spectrum nkhaus teev los ntawm International Commission on Illumination (CIE). Lub hnab tshos hluav taws xob lux meter belongs rau thaj tsam ntawm lub teeb siv kev ntsuas thev naus laus zis thiab tsim nyog rau kev ntsuas lub teeb siv hauv kev ua liaj ua teb, lub neej txhua hnub, thiab kev mus ncig sab nraud. Nws siv photoresistors li photoelectric hloov khoom siv thiab muaj DC fais fab mov. Qhov hluav taws xob hloov hluav taws xob hloov hluav taws xob, hloov pauv, photoresistor, ntsuas hluav taws xob, A / D converter, decoder, tso saib tsav tsheb, thiab cov khoom sib txuas ua ke nyob rau hauv series ntawm qhov tso zis hluav taws xob ntawm DC fais fab mov. Cov qauv siv hluav taws xob no zam kev siv lub taub hau photometric, thiab tsuas yog yuav tsum muaj 3V roj teeb rau DC fais fab mov. Lub decoder, tso saib tsav tsheb, thiab cov zaub tau muab tso rau ntawm ib daim npav sib xyaw ua ke, ua rau nws yooj yim hauv cov qauv, me me, yooj yim txav, thiab muaj qhov zoo ntawm cov lus teb rhiab. Lub tshuab ntsuas hluav taws xob UV, yog cov cuab yeej ntsuas qhov muag. Nws cov yam ntxwv yog ob txoj hauv kev ntes tau tsim los ntawm ob lub unidirectional txiav -tawm cov ntxaij lim dej optical thiab ob qhov zoo tib yam photoelectric receivers. Lub Circuit Court ib feem siv dual txoj kev amplification, uas tuaj yeem ntsuas qhov ntsuas hluav taws xob ntawm qhov ntsuas qhov xav tau. Lub stray light cutoff muaj zog
Lub hauv paus ntsiab lus ntawm kev ntsuas illuminance
Illuminance yog qhov ntom ntom ntawm cov luminous flux tau txais ntawm lub dav hlau illuminated. Illuminometer yog ib qho cuab yeej siv los ntsuas qhov illuminance ntawm lub teeb pom kev zoo thiab yog ib qho ntawm cov cuab yeej siv feem ntau hauv kev ntsuas qhov pom.
Lub hauv paus ntsiab lus ntawm illuminance meter
Lub illuminance meter muaj ob ntu: lub taub hau photometric (tseem hu ua lub teeb tau txais kev sojntsuam, suav nrog lub receiver, V (λ) khub lim, thiab cosine corrector) thiab nyeem ntawv.
