Lub hauv paus ntsiab lus ntawm Illuminance Meter thiab kev siv thev naus laus zis tau nthuav tawm cov hauv qab no
Ntau tus neeg yuav tsis nkag siab tiag tiag lub ntsuas hluav taws xob, thiab txawm tias tsis paub nws lub hauv paus ntsiab lus, thiab nws daim ntawv thov thev naus laus zis, saib hauv qab no:
Lub illuminance meter yog ib hom kev luam ntawv tsis siv neeg fiber ntau optic, yog qhov ntsuas ntawm lub teeb ci thiab ntuj lub teeb siv ntawm cov khoom siv kho qhov muag, nws daws qhov teeb meem ntawm kev ntsuas lub teeb nruam thiab tsis siv neeg kaw. Nws yog tsim los ntawm lub teeb pom kev, tsis siv neeg hloov pauv hloov hluav taws xob, lub tshuab kaw lus nkhaus, lub tshuab luam ntawv digital thiab cov khoom siv digital instantaneous, nyob rau hauv uas cov ntaub ntawv nkhaus siv cov txheej txheem kaw tsis sib haum ntawm optical fiber, thiab lub teeb pom kev yog tsim los ntawm cov lim dej thiab lub langsilicon photoelectric cell, kom pom cov spectral teb nkhaus yog nyob rau hauv txoj kab nrog qhov pom spectral nkhaus ntawm tib neeg lub qhov muag raws li tau teev tseg los ntawm International Commission on Illumination (CIE).
Lub hnab tshos hluav taws xob illuminance meter belongs rau hom illuminance ntsuas tshuab teb, uas yog tsim rau ntsuas illuminance nyob rau hauv kev ua liaj ua teb ntau lawm, lub neej txhua hnub thiab sab nraum zoov mus txawv tebchaws. Nws siv lub photoresistor ua ib qho khoom siv hluav taws xob hloov hluav taws xob, thiab nws muaj cov khoom siv hluav taws xob DC, hloov hluav taws xob hloov hluav taws xob, hloov hluav taws xob, photoresistor, ntsuas hluav taws xob, A / D converter, decoder, tsav tsheb, thiab cov zaub hauv series nyob rau hauv lem ntawm cov zis ntawm hais tias DC fais fab mov. Cov qauv siv hluav taws xob zam kev siv lub taub hau photometric, DC fais fab mov tuaj yeem siv tau nrog 3V roj teeb, lub tshuab txiav tawm, cov zaub tsav tsheb thiab cov zaub tau muab tso rau hauv daim npav sib xyaw ua ke, uas ua rau nws yooj yim hauv cov qauv, me me. , yooj yim txav, thiab nws kuj muaj qhov zoo ntawm kev ua haujlwm thiab lwm yam. Ib hom ntawm ultraviolet hluav taws xob illuminance meter, belongs rau qhov ntsuas qhov muag pom. Nws yog tus cwj pwm los ntawm ob lub unidirectional cut-off optical filters thiab ob lub zoo tib yam photoelectric receiver ua ib tug ob chav kho qhov muag txoj kev detector, lub Circuit Court ib feem ntawm ob amplification, thiaj li hais tias nws muaj peev xwm ntsuas qhov hluav taws xob nqi ntawm qhov yuav tsum tau kev xeem band, stray lub teeb txiav- tawm muaj zog heev!
Illuminance meter xeem txoj cai: illuminance yog lub dav hlau illuminated kom tau txais lub luminous flux ntawm qhov ntom ntom. Illuminance meter yog siv los ntsuas qhov illuminance ntawm lub illuminated nto ntawm lub ntsuas, yog qhov ntsuas illuminance nyob rau hauv ib qho ntawm cov cuab yeej siv ntau dua.
Illuminance meter qauv qauv: illuminance meter los ntawm lub photometric lub taub hau (tseem hu ua lub teeb sojntsuam, nrog rau lub receiver, V (λ) ntawm lub lim, cosine corrector) thiab nyeem ntawv tso saib ob feem.
