Ziziphi iiLumens, kwaye ngaba ziluncedo ekuvavanyeni izibane zokukhula?

I-lumens ngumlinganiselo weukukhanya okukhanyayo, okanye isixa sisonke sokukhanya okubonakalayo okuphuma kumthombo,Ilinganiswe bubuntununtunu beliso lomntu kubude obuthile bokukhanya.IiLumens ngowona mlinganiselo ufanelekileyo wokusetyenziswa xa uvavanya ukuba ukukhanya kuya kuyikhanyisela kangakanani na indawo yamehlo omntu.Iliso lomntu libukhali kakhulu ekukhanyeni kuluhlu olutyheli kunye nohlaza lwe-spectrum, ngokoI-100 leefotoni zokukhanya okuluhlaza zinomlinganiselo ophezulu we-lumen ngaphezu kwe-100 yeefoto zokukhanya okuluhlaza okwesibhakabhaka okanye iifoto ezili-100 zokukhanya okubomvu..

Izityalo zikhetha ukukhanya okubomvu nokuluhlaza okwesibhakabhaka.I-Lumens ikhetha ubunzima obutyheli kunye nokukhanya okuluhlaza kunye nokunciphisa ubunzima obubomvu kunye nokukhanya okuluhlaza okwesibhakabhaka,ukwenza i-lumens malunga nowona mlinganiselo umbi wokukhanya wokuvavanya ukuba ukukhanya kuya kuzikhulisa njani izityalo.

Ubunzima beLumen (tyheli) ngokuchasene neFotosynthetic Efficiency (green):

Umlinganiselo weLumens wokubonakala komntuukukhanya okukhanyayoyahluka kwiI-PAR / PPFD, ezilinganisaukukhanya okukhanyayo-Inani elipheleleyo leefotoni kwi-spectrum ebonakalayo ngaphandle kokulinganisa ukubonakala komntu.Yield Photon Flux (YPF)ifana ne-lumens kuba iifotoni zilinganiselwa kubude bazo, kodwa i-YPF ibenza ubunzima ngokusekwe kuncedo lwazo kwisityalo endaweni yeliso lomntu, kwaye i-YPF ithathela ingqalelo iifotoni ngaphandle koluhlu olubonakalayo lomntu.
