Piav cov ntsiab cai ntawm lub teeb metering thiab yuav siv li cas
Ntau tus neeg yuav tsis to taub tiag tiag lub teeb ntsuas, thiab tej zaum yuav tsis paub nws txoj cai thiab nws cov ntawv thov siv tshuab. Cia peb saib:
Lub illuminance meter yog ib qho kev luam tawm optical fiber ntau thiab cov khoom siv kho qhov muag rau kev ntsuas qhov siv ntawm cov teeb pom kev zoo 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 yog tsim los ntawm lub teeb pom kev, lub tshuab hluav taws xob hloov pauv tsis siv neeg, lub kaw lus nkhaus, lub tshuab luam ntawv digital thiab ib qho khoom siv tam sim no digital. Lub nkhaus kaw cov cuab yeej siv cov txheej txheem kho qhov muag fiber ntau frictionless, thiab lub teeb pom kev yog lub lim thiab xiav silicon Nws yog tsim los ntawm cov cell photovoltaic kom pom cov spectrum teb nkhaus raws li tib neeg kev pom spectrum nkhaus tau teev tseg los ntawm International Commission on Illumination ( CIE).
Lub hnab tshos hluav taws xob illuminance meter belongs rau kev ua haujlwm ntawm kev ntsuas teeb pom kev zoo thiab tsim nyog rau kev ntsuas kev teeb pom kev hauv kev ua liaj ua teb, lub neej txhua hnub, thiab mus ncig sab nraud. Nws siv lub photoresistor ua lub tshuab hloov hluav taws xob photoelectric, thiab muaj cov khoom siv hluav taws xob DC, hluav taws xob hloov hluav taws xob, hloov hluav taws xob, photoresistor, ntsuas Circuit Court, A / D converter, decoder, tus tsav tsheb thiab cov zaub txuas nrog hauv series. mus rau qhov kawg tso zis ntawm DC fais fab mov. . Cov qauv siv hluav taws xob zam kev siv lub taub hau photometric, thiab tsuas yog siv 3V roj teeb rau DC fais fab mov. Lub decoder, tso saib tsav tsheb thiab cov zaub tau muab tso rau ntawm daim npav sib xyaw ua ke, ua rau nws yooj yim hauv cov qauv, me me, yooj yim txav, thiab teb. Etc. Ib lub ntsuas hluav taws xob ultraviolet illuminance meter belongs rau qhov ntsuas qhov muag. Nws yog tus cwj pwm los ntawm ob txoj kev kho qhov muag pom muaj li ntawm ob lub unidirectional cut-off optical lim thiab ob qhov zoo tib yam photoelectric receivers. Lub Circuit Court ib feem siv dual-path amplification, thiaj li hais tias tus nqi hluav taws xob ntawm qhov yuav tsum tau kuaj band yuav raug ntsuas kom raug. Muaj zog astigmatism txiav tawm
Lub hauv paus ntsiab lus ntawm kev ntsuas lub teeb pom kev zoo: Illuminance yog qhov ntom ntom ntawm cov luminous flux tau txais ntawm lub dav hlau illuminated. Lub illuminance meter yog ib qho cuab yeej siv los ntsuas qhov illumination ntawm qhov chaw illuminated. Nws yog ib qho ntawm cov cuab yeej siv feem ntau hauv kev ntsuas qhov pom kev.
Lub hauv paus ntsiab lus ntawm lub 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.
