Ukukhetha i-headlamp yenkampu

Kutheni ufuna ifanelekile intloko Ngeenkampu, i-rindesms ziphathwa kwaye zilula, kwaye zibalulekile ekuhambeni kobusuku, izixhobo zokucwangcisa kunye namanye amaxesha.

1, Ngcono: Ukuphakama kwe-LOOMEns, ukuqaqamba ukukhanya!

Ngaphandle, amaxesha amaninzi 'aqaqambile "kubaluleke kakhulu. Umzekelo, intaba yasebusuku okanye uphononongo lomqolomba, ukukhanya kwanele kunokukhuphela, ukuwa, okanye uphose uphawu olubalulekileyo; "Izibane" ziya kukwenza "intlekele". Ukuba ufuna ukhanye, uya kwandula unikele ingqalelo kwiparameter ye-lumens.

(1) Umlinganiso wokuqaqamba ukusuka kuLumens

Ubomi, sihlala sisithi ukhanyiso "likhanyise okanye hayi", enyanisweni, libhekisa kwi-zunguus flux. Iyunithi ye-Flux ye-LUME i-lumen, ebonisa amandla okukhanya. Ukuba ufuna ukuthenga ukukhanya okuqaqambileyo, simele sinikele ingqalelo kwi-camens yale parameter. Ukukhanya okuphezulu kukuvumela ukuba ubone ngokucacileyo imeko ephambi kwakho.

(2) Ixabiso elikhulu le-lumen, ukukhanya okuqaqambileyo.

Kubai-therades engaphandle kwaye I-Flashlights, Kukho ubudlelwane obuhle phakathi kwe-lumens kunye nokuqaqamba: Eyona nto iphambili kunexabiso le lumen, enkulu enkulu ye-lumex, kokukhona mandla anethanga lomthombo wokukhanya. Umzekelo, aI-1000 ye-lumen lumen iqaqambile kune I-300 LEN.

(3) Ukukhetha ukukhanya

Ukukhanya okuphezulu kwexabiso lemveliso kukuphakama, xa uthenga kufuneka adityaniswe nokusetyenziswa kwabo kwendawo. I-100 lumens ilingana nokukhanya kwamakhandlela ama-8, imisebenzi ye-HARD yokuhamba ngenkampu yokuthengisa iimpahla ukukhetha i-100 ~ 200 yemveliso yemveliso yanele; Iimveliso ezincinci ezingxamisekileyo ikakhulu zikwi-50 lumens okanye ngaphezulu, kodwa zinokuhlangabezana neemfuno zokuKhanya.

Ukuba uthatha inxaxheba kwimidlalo yangaphandle inemfuno eziphezulu zokukhanyisa, unokuthatha ingqalelo kwiimveliso ezingama-200 ~ 500 lumens lumens. Ukuba kukho iimfuno eziphezulu, njengokuhamba ngokukhawuleza (ilizwe ebusuku), okanye imfuneko yokukhanyisa indawo enkulu, ungaqwalasela i-500 ~ I-1000 lumens yemveliso.

Iimfuno zobungcali, ezinjengokuKhangela ngokuhlangula, unokujonga ngaphezulu kweI-1000 Lumens intloko. Ukuqaqamba akuthethi ukuba kude, ngamanye amaxesha kufuneka kukhangele kwaye kubhiyoze, ngokuqinisekileyo ukukhanya kukude, ke ufuna enye iparameter ekhankanywe ngezantsi.
