Kodi nyali yakumutu imawala bwanji?

Lumen ndi muyeso wofunikira wa zida zowunikira. Kodi nyali yakumutu imawala bwanji?
Inde, pali mgwirizano wofanana pakati pa lumen ndi kuwala, ngati zinthu zina zonse zili zofanana. Koma lumen sizomwe zimatsimikizira kuwala.

Chofunikira kwambiri kusankha nyali yakumutu ndikudziwa kuti ma lumens (lm), otchedwa lumens mutha kuwatenga ngati kuwala, 50 lumens ndi 300 lumens, 300 lumens kuwala ndi apamwamba, apamwamba nambala ya lumen, apamwamba kuwala. Ngati mukufuna kukumba kuti lumen ndi chiyani, ndiye kuwala kwa kuwala kowoneka bwino komwe kumachokera ku gwero la kuwala.

Ndiye, nyali zoyang'ana kwambiri, zimakhala bwino?
Osati chimodzimodzi. Laser pointer imayang'ana kwambiri, yamphamvu komanso yolowera, koma mfundo yokhayo; tochi yamphamvu imawombera patali, koma imasiya malo ambiri owunikira…ndiye kuti chilichonse chili chocheperako. Poyang'ana Pang'onopang'ono ya nyali, timawona momwe diso la munthu limawonekera, ndipo gawo lowala limalola wogwiritsa ntchito kuwona malo ofunikira popanda kutembenuza Nthawi zambiri. M'malo mwake, masomphenya aumunthu ndi malo ovuta kwambiri pa madigiri 10, madigiri 10 ~ 20 amatha kuzindikira zambiri, ndipo madigiri 20 mpaka 30 amakhudzidwa kwambiri ndi zinthu zamphamvu. Kutengera malingaliro awa, titha kudziwa mtundu woyenera wa mzere wowunikira mutu.

Malinga ndi zomwe mumagwiritsa ntchito, sankhaninyali yapamwamba ya lumens or nyali yotsika ya lumens.

50-100 Lumens
Nthawi zambiri, ndikwabwino kukhala ndi nyali zosachepera 50 zowunikira, zoyenera momwe zinthu ziliri: Lowani nawo kalabu yakunja ndi atsogoleri amagulu ndi owongolera Kuphika, msasa wodyera.
100-200 Lumens
Zowunikira zopitilira 100 zowunikira zimatha kuthana ndi zovuta zambiri, ngakhale kuwala kumakhalabe kochepa, koma bola mukuyenda pang'onopang'ono, sipadzakhala vuto lalikulu. Komabe, sikuvomerezedwa kukhala mtsogoleri wamagulu. Zomwe zimagwiritsidwa ntchito: msasa wokwera phiri Kuphika, kudya

Ma lumens opitilira 200, kapena kupitilira apo300 lumens headlampakhoza kukulolani kuyenda usiku, chifukwa cha kuwala kwapamwamba kwambiri, kuti muthe kumvetsa bwino malo ozungulira, kutsogolo, koma mtengo wa nyali wa lumens ndi wapamwamba kwambiri. Zomwe zimagwira ntchito: kukwera phiri Kubwerera kumtsinje Kuthamanga kwambiri.

Choncho, Sankhani nyali yanu tsopano!
