Cov ci ntsa iab ntawm lub teeb emitting diode (lwm yam ntxiv) yog ntsuas los ntawm luminous flux, uas yog qhov cuam tshuam ntawm lub teeb ntawm lub qhov muag, kho rau qhov sib txawv wavelengths. Luminous flux yog ntsuas los ntawm lumens, uas sib haum rau tocandelas ntawm lub teeb, los yog luminous siv, emitted tshaj ib tug solidangle.

Ntxiv mus, dab tsi yog lumens hauv LED teeb?

Hauv cov ntsiab lus yooj yim, Lumens (los ntawm lm) yog ameasure ntawm tag nrho cov nyiaj ntawm pom lub teeb (rau tib neeg lub qhov muag) los ntawm ib tug teeb lossis lub teeb ci. Qhov siab dua lub lumen ntsuam xyuas qhov "ci" qhov teeb yuav tshwm. Peb txhua tus tau yuav 50W lossis 60W cov teeb pom kev zoo lossis cov teeb pom kev zoo nyob rau yav dhau los cia siab tias yuav muaj qhov ci ntsa iab.

Ib yam nkaus, siv lub twj ntsuas twg los ntsuas qhov ci ntawm lub teeb? duab ntsuas

Tom qab ntawd, lo lus nug yog, chav tsev ci ci yog dab tsi?

Lub candela ib square meter (cim: cd / m2) is the derived SI chav tsev ntawm luminance. Cov chav tsev yog nyob ntawm candela, SI chav tsev ntawm luminous siv, thiab lub square meter, SI chav tsev ntawm cheeb tsam. Raws li kev ntsuas ntawm lightemitted per chav tsev cheeb tsam, qhov no chav tsev nquag siv los hais qhia txog ci ntsa iab ntawm ib qho khoom siv tso saib.

Yuav ua li cas ci yog 4500 lumens?

Dark Sky-Friendly Lights Xaiv lub teeb uas muaj tag nrho cov teeb pom kev zoo ntawm 4500 lumens los yog tsawg dua. Qhov no yog sib npaug li kwv yees li ntawm plaub60-watt (lossis ib qho 250 watt) qhov muag teeb. Ntawd yog qhov tsaus ntuj ntau hmo.
