Lub teeb kho koob tshuaj yog xam nrog cov qauv no:
Lub zog ceev x Sijhawm = koob
Hmoov zoo, cov kev tshawb fawb tsis ntev los no feem ntau siv cov qauv txheej txheem los piav txog lawv cov txheej txheem:
Hwj chim ceev nyob rau hauv mW / cm² (milliwatts ib centimeter squared)
Sijhawm hauv s (seconds)
Dose hauv J / cm² (Joules ib centimeter squared)
Rau kev kho lub teeb nyob hauv tsev, lub zog ceev yog li qhov tseem ceeb uas koj yuav tsum paub - yog tias koj tsis paub, koj yuav tsis paub ntev npaum li cas los siv koj lub cuab yeej kom ua tiav ib koob tshuaj.Nws tsuas yog ib qho kev ntsuas ntawm lub teeb siv zog npaum li cas (lossis pes tsawg photons nyob hauv thaj tsam ntawm qhov chaw).
Nrog lub kaum sab xis tso zis LEDs, lub teeb tau nthuav tawm thaum nws txav mus, npog thaj tsam dav thiab dav.Qhov no txhais tau hais tias tus txheeb ze lub teeb siv ntawm ib qho chaw twg tau qaug zog vim qhov kev ncua deb ntawm qhov chaw nce.Qhov sib txawv ntawm lub kaum sab xis ntawm LEDs kuj cuam tshuam rau lub zog ceev.Piv txwv li, 3w / 10 ° LED yuav tsim lub teeb lub zog ceev dua li 3w / 120 ° LED, uas yuav ua rau lub teeb tsis muaj zog hla thaj tsam loj.
Kev tshawb fawb txog kev kho lub teeb zoo li siv lub zog ntom ntom ntawm ~ 10mW / cm² txog li max ~ 200mW / cm².
Dose tsuas yog qhia koj ntev npaum li cas lub zog ceev tau thov rau.Kev siv lub teeb siab dua txhais tau tias yuav tsum muaj sijhawm thov tsawg dua:
5mW / cm² thov rau 200 vib nas this muab 1J / cm².
20mW / cm² thov rau 50 vib nas this muab 1J / cm².
100mW / cm² thov rau 10 vib nas this muab 1J / cm².
Cov chav nyob ntawm mW / cm² thiab vib nas this muab qhov tshwm sim hauv mJ / cm² - tsuas yog muab qhov ntawd los ntawm 0.001 kom tau hauv J / cm².Yog li ntawd, tag nrho cov mis, noj rau hauv tus account standard units yog li ntawd:
Dose = Fais Fab Density x Sijhawm x 0.001
