Xaiv cov headlamp rau kev pw hav zoov

Vim li cas koj thiaj li xav tau ib qho haum lub npe Rau kev mus pw hav zoov, cov headlasps yog portable thiab lub teeb, thiab yog qhov tseem ceeb rau kev mus ncig thaum hmo ntuj, kev teeb tsa khoom thiab lwm lub caij.

1, lub zog dua: qhov siab dua cov lumens, lub teeb ci ci!

Nyob rau sab nraum zoov, ntau zaus "ci" yog qhov tseem ceeb heev. Piv txwv li, hmo ntuj kab roob lossis tshawb txog lub qhov tsua, lub ci ci tsis txaus yuav tripped, poob, lossis plam ib qho kev kos npe tseem ceeb; "Lub teeb" yuav ua rau koj mus rau hauv "kev puas tsuaj". Yog tias koj xav tau ci, ces koj yuav tsum them sai sai rau qhov ntsuas ntawm cov lumens.

(1) ntsuas kev ntsuas ntawm kev ci ntsa iab los ntawm lumens

Lub neej, peb nquag hais lub teeb "ci ntsa iab los yog tsis", qhov tseeb, hais txog cov luminous flux. Chav tsev ntawm luminous flux yog lumen, uas qhia txog lub peev xwm ntawm lub teeb ci ci. Yog tias koj xav yuav lub teeb ci ntsa iab, peb yuav tsum them sai sai rau cov lumens ntawm qhov ntsuas no. Kev ci siab rau koj kom pom meej qhov ib puag ncig ntawm koj xub ntiag.

(2) Cov loj dua cov nqi lumen, lub teeb ci ntsa iab.

RauSab nraum zoov taub hau thiab teeb liab, Nws muaj kev sib raug zoo ntawm cov lumens thiab ci ci: qhov ntau dua cov lumen tus nqi, qhov ntau dua cov luminous flux, qhov ntau dua cov nyom hluav taws xob ntawm lub teeb ci. Piv txwv li, a1000 lumen headlamp yog ci dua a 300 lumen headlamp.

(3) Qhov kev xaiv ntawm kev ci ntsa iab

Qhov siab dua qhov ci ntawm cov khoom tus nqi kuj tseem siab dua, thaum kev yuav yuav tsum tau ua ke nrog lawv tus kheej siv cov xwm txheej. 100 lumens yog sib npaug rau lub teeb ntawm 8 tswm ciab, tus thawj sab nraum zoov kev pw hav zoov hiking ua ub no los xaiv 100 ~ 200 lumens ntawm cov khoom txaus; Mini lub teeb pom kev kub ntxhov yog feem ntau nyob rau hauv 50 lumens lossis li ntawd, tab sis kuj tuaj yeem ua tau raws li cov kev xav tau teeb meem.

Yog tias koj koom nrog kev ua kis las sab nraum zoov muaj cov teeb meem siab dua rau teeb pom kev zoo, koj tuaj yeem xav txog 200 ~ 500 lumens cov khoom lag luam. Yog tias muaj cov qib siab, xws li taug kev nrawm heev (hauv lub teb chaws hla kev), lossis qhov xav tau taws qhov chaw loj, koj tuaj yeem xav 500 ~ 1000 Lumens ntawm cov khoom.

Cov kev xav tau kev tshaj lij, xws li kev tshawb nrhiav kev cawm seej, koj tuaj yeem xav ntau dua1000 Lumens lub npeCov. Ci tsis tau txhais tau tias deb, qee zaum yuav tsum tau tshawb thiab saib, koj yeej cia siab tias lub teeb pom me ntsis, ces koj xav tau lwm qhov parameter hais hauv qab no.
