8 meters 80W hnub ci txoj kev teeb illuminance ntau npaum li cas?

Hnub ci txoj kev teeb yog ib yam khoom siv teeb pom kev zoo uas siv lub hnub ci zog los tsim hluav taws xob, uas hloov lub hnub ci zog rau hauv hluav taws xob los ntawm lub hnub ci vaj huam sib luag, thiab tom qab ntawd khaws hluav taws xob los ntawm cov roj teeb, thiab thaum kawg illuminates los ntawm LED qhov muag teev. Yog li, ntau npaum li cas illumination ntawm 8 meters 80W hnub ci txoj kev teeb?

Ua ntej, peb yuav tsum to taub dab tsi illumination yog dab tsi. Illuminance yog hais txog lub luminous flux tau txais hauv ib cheeb tsam, feem ntau qhia hauv lux, 1 lux yog sib npaug rau 1 lumen / square meter. Qhov siab dua qhov illuminance, qhov ntau lub teeb tau txais hauv ib cheeb tsam, qhov zoo dua qhov teeb pom kev zoo.

Rau hnub ci txoj kev teeb, lawv cov teeb pom kev zoo cuam tshuam los ntawm ntau yam, suav nrog kev hloov pauv ntawm cov hnub ci vaj huam sib luag, lub zog cia lub peev xwm ntawm cov roj teeb, thiab cov teeb pom kev zoo ntawm LED qhov muag teev. Feem ntau, illumination ntawm hnub ci txoj kev teeb nyob nruab nrab ntawm 10 lux thiab 30 lux.

Raws li cov ntaub ntawv muab, lub zog ntawm 8 meters ntawm 80W hnub ci txoj kev teeb yog 80W, uas yog hais txog lub zog ntawm lub hnub ci vaj huam sib luag. Txawm li cas los xij, txij li kev hloov dua siab tshiab ntawm cov hnub ci vaj huam sib luag feem ntau yog nruab nrab ntawm 15% thiab 20%, lub zog uas tuaj yeem hloov mus rau hauv hluav taws xob tau raug txo qis. Piv txwv li kev hloov dua siab tshiab ntawm 15%, lub zog tiag tiag hloov mus rau lub zog hluav taws xob yog 80W * 15%=12W.

Tom ntej no, peb yuav tsum xav txog qhov luminous efficiency ntawm LED qhov muag teev. Feem ntau, luminous efficiency ntawm LED qhov muag teev yog nyob nruab nrab ntawm 80 lumens / watt thiab 100 lumens / watt. Piv txwv tias qhov kev ua haujlwm luminous ntawm LED teeb yog 80 lumens / watt, qhov tseeb luminous flux yog 12W * 80 lumens / watt=960 lumens.

Thaum kawg, peb yuav tsum hloov qhov tseeb luminous flux rau hauv illuminance. Txij li cov teeb pom kev zoo ntawm lub hnub ci txoj kev teeb pom kev loj loj, peb yuav tsum suav cov teeb pom kev ntawm ib qho chaw nyob rau hauv cov teeb pom kev zoo ntawm txoj kev teeb. Piv txwv tias txoj kev teeb pom kev zoo ntawm 10 square metres, qhov teeb pom kev ntawm qhov taw tes yog 960 lumens / 10 square meters=96 lux.

Nyob rau hauv cov ntsiab lus, lub illumination ntawm 8 meters 80W hnub ci txoj kev teeb yog hais txog 96 lux. Nws yuav tsum raug sau tseg tias qhov no tsuas yog kev kwv yees xwb, thiab qhov teeb pom kev tiag tiag yuav raug cuam tshuam los ntawm lwm yam, xws li kev tsim lub teeb, kev xav ntawm ib puag ncig, thiab lwm yam.
