Vim li cas koj thiaj xav tau qhov tsim nyog teeb taub hau rau kev mus pw hav zoov, headlamps yog portable thiab lub teeb yuag, thiab yog qhov tseem ceeb rau kev mus ncig thaum hmo ntuj, teeb tsa cov khoom siv thiab lwm lub sijhawm.
1, ci dua: lub lumens siab dua, lub teeb ci dua!
Nyob rau sab nraum zoov, ntau zaus "ci" tseem ceeb heev. Piv txwv li, hmo ntuj kab roob los yog tshawb xyuas lub qhov tsua, qhov ci ntsa iab tsis txaus yuav raug tripped, ntog, lossis nco ib qho tseem ceeb kos npe; "lamps" yuav ua rau koj mus rau hauv "kev txom nyem". Yog tias koj xav tau qhov kaj, ces koj yuav tsum tau them sai sai rau qhov ntsuas ntawm lumens.
(1) Kev ntsuas qhov ci ntawm lumens
Lub neej, peb feem ntau hais tias lub teeb "ci los yog tsis", qhov tseeb, yog hais txog lub luminous flux. Chav tsev ntawm luminous flux yog lumen, uas qhia txog lub peev xwm ntawm lub teeb ci. Yog tias koj xav yuav lub teeb pom kev zoo, peb yuav tsum them sai sai rau lub lumens ntawm qhov ntsuas no. High brightness tso cai rau koj kom pom tseeb ib puag ncig nyob rau hauv pem hauv ntej ntawm koj.
(2) Qhov loj dua tus nqi lumen, lub teeb ci dua.
Rausab nraum zoov headlamps thiab teeb nyem, muaj kev sib raug zoo ntawm lumens thiab brightness: qhov ntau dua tus nqi lumen, qhov ntau dua qhov luminous flux, qhov ntau dua lub zog ntawm lub teeb ci. Piv txwv li, a1000 lumen headlamp yog ci dua ib 300 lumen taub hau.
(3) Kev xaiv qhov kaj
Qhov siab dua qhov ci ntsa iab ntawm cov khoom lag luam tus nqi kuj yog siab dua, thaum yuav yuav tsum tau ua ke nrog lawv tus kheej siv ntawm qhov chaw. 100 lumens yog sib npaug rau lub teeb ntawm 8 tswm ciab, thawj sab nraum zoov camping hiking kev ua si xaiv 100 ~ 200 lumens ntawm cov khoom txaus; Cov khoom siv teeb pom kev kub ceev mini feem ntau yog nyob rau hauv 50 lumens los yog li ntawd, tab sis kuj tuaj yeem ua tau raws li qhov xav tau teeb pom kev zoo.
Yog tias koj koom nrog kev ua si sab nraum zoov muaj qhov xav tau ntau dua rau kev teeb pom kev zoo, koj tuaj yeem xav txog 200 ~ 500 lumens cov khoom. Yog tias muaj cov kev xav tau siab dua, xws li taug kev nrawm heev (hmo ntuj hla lub tebchaws), lossis xav tau kev teeb pom kev hauv thaj chaw loj, koj tuaj yeem xav txog 500 ~ 1000 lumens ntawm cov khoom.
Kev xav tau kev tshaj lij, xws li kev tshawb nrhiav cawm, koj tuaj yeem xav txog ntau dua1000 lumens teeb taub hau. Bright tsis txhais hais tias nyob deb, qee zaum yuav tsum tau tshawb nrhiav thiab saib xyuas, koj yeej cia siab tias lub teeb nyob deb me ntsis, ces koj xav tau lwm qhov ntsuas tau hais hauv qab no.
