Maonekedwe a kuyatsa ngalande
Chifukwa chakuti gawo lililonse la ngalandeyo lili ndi zofunika zowala mosiyanasiyana, kamangidwe ka nyalezo n’kosiyananso. Zigawo zoyambira (zigawo zamkati) mkati mwa ngalandeyo zimakonzedwa mosiyanasiyana, ndipo magawo omwe amalowera pakhomo ndi kutuluka ayenera kukonzedwa mosiyanasiyana malinga ndi zofunikira zowala komanso momwe nyali zosankhidwa zimayendera.
Kusankha kuyatsa kwa ngalande
Zowunikira zachikhalidwe monga nyali za incandescent, nyali zachitsulo za halide, nyali zothamanga kwambiri za sodium, nyali zotsika kwambiri za sodium, ndi nyali zamphamvu kwambiri za mercury nthawi zambiri zimakhala ndi zovuta monga zounikira zocheperako, kugawa kosawoneka bwino, kugwiritsa ntchito mphamvu zambiri, komanso moyo waufupi. span, zomwe zimatsogolera mwachindunji kuyatsa koyipa m'misewu yayikulu. Sitingathe kukwaniritsa zofunikira zowunikira mumsewu waukulu, zomwe zimakhudza kwambiri chitetezo cha galimoto.
Zowunikira zowunikira mumsewu ziyenera kukwaniritsa izi:
1. Iyenera kukhala ndi deta yathunthu ya photometric ndikupanga mapangidwe asayansi ndi omveka bwino;
2. Osachepera kukwaniritsa zofunika za IP65 chitetezo mlingo;
3. Magawo ophatikizidwa a nyali ayenera kukhala ndi mphamvu zokwanira zamakina kuti akwaniritse zofunikira za kukana zivomezi;
4. Zida ndi zigawo za nyali ziyenera kukhala ndi dzimbiri komanso kukana kwa dzimbiri;
5. Mapangidwe a nyaliyo ayenera kupereka mwayi wokonza ndi kusinthidwa.
