Lub hauv paus ntsiab lus ntawm illuminance meter thiab daim ntawv thov ntawm cov cuab yeej qhia
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, nrog rau nws daim ntawv thov thev naus laus zis, saib hauv qab no:
Lub illuminance meter yog ib hom kev luam ntawv tsis siv neeg optical fiber, uas yog ib qho kev ntsuas qhov muag rau kev ntsuas qhov siv ntawm cov khoom siv dag zog thiab lub teeb ntuj, thiab 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 tau txais cov kev sib txhuam 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 rau 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 thev naus laus zis teb, uas tsim nyog rau kev ntsuas qhov pom kev hauv kev ua liaj ua teb, lub neej txhua hnub thiab kev mus ncig sab nraud. 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 nrog 3V roj teeb, lub tshuab txiav tawm, cov zaub tsav tsheb thiab cov zaub tau muab tso rau ntawm daim npav sib xyaw ua ke, ua kom yooj yim hauv cov qauv, me me, yooj yim txav, thiab kuj muaj qhov zoo ntawm cov lus teb rhiab. Ib hom ntawm ultraviolet hluav taws xob illuminance meter, belongs rau optical test instrument. Nws yog tus cwj pwm los ntawm ob lub unidirectional cut-off optical filters thiab ob lub zoo tib yam photoelectric receivers ua ib tug ob chav kho qhov muag Circuit Court detector, lub Circuit Court ib feem ntawm ob amplification, thiaj li yuav tau raug ntsuas qhov hluav taws xob nqi ntawm qhov yuav tsum tau xeem band, stray lub teeb. kev 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 illuminated nto ntawm lub ntsuas, yog ib qho ntawm cov cuab yeej siv tshaj plaws hauv kev ntsuas qhov illuminance.
Teeb pom kev zoo
Lub hauv paus ntsiab lus ntawm illuminance meter: illuminance meter los ntawm lub photometric lub taub hau (tseem hu ua lub teeb sojntsuam, nrog rau cov receiver, V (λ) ntawm lub lim, cosine corrector) thiab nyeem ntawv ob feem.
