Iyini i-lumen ye-suitbale yokusetshenziswa endlini?

I-lumen iyiyunithi yokulinganisa inani lokukhanya okukhishwe umthombo wokukhanya. Ukukhanya kwesibani se-strip kuvame ukulinganiswa ngama-lumen ngenyawo noma ngemitha, kuye ngeyunithi yokulinganisa esetshenzisiwe. Uma ukukhanya kugqama kakhuluisibani sokukhumula, inani le-lumen liphakeme.

Landela lezi zinyathelo ukuze ubale umphumela we-lumen womthombo wokukhanya:

1. Thola ukugeleza okukhanyayo: Inani eliphelele lokukhanya okukhishwe umthombo wokukhanya, okulinganiswa ngama-lumens, libizwa ngokuthi ukugeleza okukhanyayo. Lolu lwazi lungatholakala kushidi ledatha noma iphakheji yomthombo wokukhanya.

2. Bala usayizi wendawo: Uma ufuna ukwazi umphumela we-lumen ngefithi lesikwele noma imitha, kufanele ubhale indawo ekhanyiswayo. Ukuze wenze kanjalo, hlukanisa ukugeleza okukhanyayo ngendawo yonke ekhanyisiwe. Uma umthombo wokukhanya we-lumen ongu-1000 ukhanyisa igumbi elingamamitha ayizikwele angu-100, umphumela we-lumen ngefithi lesikwele u-10 (1000/100 = 10).

3. buyisela i-engeli yokubuka: Uma ufuna ukwazi umphumela we-lumen we-engeli ethile yokubuka, kufanele ubuyisele i-engeli yokukhanya yomthombo wokukhanya. Lokhu kuvame ukuvezwa ngamadigri futhi kungatholakala kudathashethi noma kuphakheji. Ungasebenzisa ifomula ukubala umphumela we-lumen we-engeli ethile yokubuka, noma ungasebenzisa umthetho wesikwele ophambene ukuze uthole isilinganiso.

Khumbula ukuthi ukusebenza kahle komthombo wokukhanya kungahluka ngokuya ngeminye imingcele, njengokukhanya kwezindawo endaweni ekhanyiswayo. Ngenxa yalokho, ukuphuma kwe-lumen kumane kuyisici esisodwa okufanele usicabangele lapho ukhetha umthombo wokukhanya.

Ukukhanya okufanele kwe-umugqa wokukhanyisa wangaphakathikuyahlukahluka kuye ngohlobo kanye nenhloso yokukhanya. Kodwa-ke, ububanzi obuhle bokukhanya kwe-LED strip bungaba phakathi kwama-lumen angu-150 no-300 ngonyawo (noma ama-lumen angu-500 no-1000 ngemitha). Lolu bubanzi lukhanya ngokwanele ukunikeza ukukhanya okufanele kwemisebenzi efana nokupheka, ukufunda, noma umsebenzi wekhompyutha, kuyilapho futhi lusebenzisa amandla kahle futhi lufaka isandla ekudalweni kwendawo ekhululekile nethokomele. Khumbula ukuthi izinga lokushisa lombala kanye nesimo se-strip, kanye nebanga eliphakathi kwe-strip kanye nobuso obukhanyiswayo, konke kungaba nomthelela ekuphumeni kwe-lumen ethile.
