Ukukhetha i-Headlamp yokukhempa

Kungani udinga kufanelekile -HicAmp Ukukhempa, ama-Headenland aphathekayo futhi angasindi, futhi abalulekile ekuhambeni ebusuku, ukuhlela imishini nezinye izikhathi.

1, Okugqamile: Ukuphakama kwama-lumens, ukukhanya okukhanyayo!

Engaphandle, izikhathi eziningi "ezikhanyayo" zibaluleke kakhulu. Isibonelo, intaba yasebusuku entabeni noma hlola umhume, ukugqama akwanele kungakhishwa, ukuwa, noma uphuthelwe uphawu olubalulekile; "Izibani" zizokungenisa "inhlekelele". Uma udinga ukugqama, khona-ke kufanele unake ipharamitha yama-lumens.

(1) Ukulinganiswa kokukhanya okuvela ku-lumens

Impilo, sivame ukusho ukukhanya ngokuthi "kukhanya noma cha", eqinisweni, kubhekisele ku-flux ekhanyayo. Iyunithi le-luminous flux yi-lumen, ekhombisa umthamo okhanyayo womthombo wokukhanya. Uma ufuna ukuthenga ukukhanya okukhanyayo, kufanele sinake ama-lumens ale pharamitha. Ukukhanya okuphezulu kukuvumela ukuthi ubone ngokucacile imvelo phambi kwakho.

(2) Kukhudlwana inani le-lumen, kukhanya ukukhanya.

IngomaneAma-Headlamp angaphandle na- ama-flashlights, kunobudlelwano obuhle phakathi kwama-lumens nokukhanya: kukhudlwana inani le-lumun, kukhudlwana i-flux elikhanyayo, kukhudlwana amandla akhazimulayo omthombo wokukhanya. Isibonelo, aI-1000 Lumen Headlamp kukhanya kuno I-headlamp engama-300 le-lumen.

(3) Ukukhethwa kokukhanya

Ukukhanya okuphezulu kwentengo yomkhiqizo nakho kuphakeme futhi, lapho ukuthenga kudinga ukuhlanganiswa nokusetshenziswa kwawo kwesigameko. Ama-lemens ayi-100 alingana nokukhanya kwamakhandlela ayi-8, imisebenzi ephambili yokuhamba ngezinyawo yangaphandle ukukhetha ama-lumens ayi-100 ~ 200 wemikhiqizo ngokwanele; Imikhiqizo yokukhanyisa okuphuthumayo ye-Mini iningi kakhulu kuma-lumens angama-50 noma ngaphezulu, kepha futhi ingahlangabezana nezidingo zokukhanyisa.

Uma ubamba iqhaza emidlalweni yangaphandle unezidingo eziphakeme zokukhanyisa, ungacabanga ngemikhiqizo engama-200 ~ 500 le-lumens. Uma kunezidingo eziphakeme, njengokuhamba ngokushesha okukhulu (ubusuku obusezingeni eliphezulu kuyasebenza), noma isidingo sokukhanyisela indawo enkulu, ungabheka ama-lumens angama-500 ~ 1000 wemikhiqizo.

Izidingo zobungcweti, njengokusesha kokuhlenga, ungabheka ngaphezu kwalokhoI-1000 lumens -HicAmp. Okukhanyayo akusho kude, kwesinye isikhathi kudingeka kusheshe ukusesha nokubona, ngokuqinisekile unethemba lokuthi ukukhanya kukhulu kakhulu, khona-ke udinga enye ipharamitha eshiwo ngezansi.
