Hauv kev yuav khoomsab nraum zoovtaub hauteebthiabmus pw hav zoovlanterns feem ntau pom lo lus "lumen", koj puas to taub nws?
Lumens = Lub teeb tso zis.Hauv cov ntsiab lus yooj yim, Lumens (cim los ntawm lm) yog qhov ntsuas ntawm tag nrho cov teeb pom kev zoo (rau tib neeg lub qhov muag) los ntawm lub teeb lossis lub teeb ci.
Feem ntausab nraum zoovmus pw hav zoovteeb, headlamp los yog flashlightfixtures yog LED teeb, uas siv tsawg zog thiab yog li ntawd muaj ib tug qis watt-ntsuas.Qhov no ua rau cov watts peb siv los ntsuas qhov muag teeb ci tsis siv tau lawm, yog li cov tuam txhab hloov mus rau lumens.
Lumen, lub cev lub cev piav qhia txog qhov flux ntawm lub teeb, ntsuas los ntawm "lm", luv luv rau "lumen".Qhov siab dua tus nqi lumen, lub teeb ci dua.Yog tias koj tsis paub meej txog tus lej lumen, daim ntawv qhia ntawm cov teeb ci rau LED teeb yuav muab qhov tseeb rau koj.Ntawd yog, thaum koj xav tau ib qho LED uas tuaj yeem ua tiav cov txiaj ntsig ntawm 100W incandescent teeb, xaiv 16-20W LED thiab koj yuav tau txais tib qhov ci.
Nyob rau sab nraum zoov, raws li ntau hom kev ua ub no feem ntau xav tau ntau lub lumen, koj tuaj yeem xa mus rau cov ntaub ntawv hauv qab no: hmo ntuj mus pw hav zoov: txog 100 lumen hmo hiking, hla (xav txog huab cua hloov xws li nag thiab huab cua): 200 ~ 500 lumen txog Txoj kev khiav lossis lwm yam kev sib tw hmo ntuj: 500 ~ 1000 lumen kev tshawb nrhiav thiab cawm hmo ntuj: ntau tshaj 1000 lumen
Ceev faj thaum sivheadlights sab nraum zoov(tshwj xeeb yog cov uas muaj lumens siab), tsis txhob taw tes rau tib neeg lub qhov muag.Lub teeb ci dhau lawm tuaj yeem ua rau tib neeg lub qhov muag puas tsuaj.
