Ekuthengweni kwengaphandleikhandaizibanifuthiukukhempaizibani zivame ukubona igama elithi "lumen", uyaliqonda?
I-Lumens = Okukhipha Okukhanyayo.Ngamagama alula, ama-Lumen (achazwa ngo-lm) ayisilinganiso senani lokukhanya okubonakalayo (esweni lomuntu) esivela esibani noma emthonjeni wokukhanya.
Abaningiezivamile ongaphandleukukhempaukukhanya, isibani noma ithoshiizinto ezilungiswayo izibani ze-LED, ezisebenzisa amandla amancane futhi ngenxa yalokho zinesilinganiso esiphansi se-watt.Lokhu kwenza ukuthi ama-watt esiwasebenzise ukukala ukukhanya kwelambu lokukhanya angabe esasebenza, ngakho abakhiqizi bashintshela ku-lumens.
I-Lumen, iyunithi ebonakalayo echaza ukugeleza kokukhanya, ikalwe ngokuthi “lm”, okufushane ngokuthi “lumen”.Lapho inani le-lumen liphakeme, isibani siyakhanya.Uma ungaqiniseki ngezinombolo ze-lumen, leli shadi le-incandescent yezibani ze-LED lingase likunikeze umkhondo.Okusho ukuthi, uma ufuna i-LED engafinyelela umphumela wesibani se-incandescent esingu-100W, khetha i-LED engu-16-20W futhi uzothola ukukhanya okufanayo.
Ngaphandle, ngokwezinhlobo ezahlukene zemisebenzi ngokuvamile edinga amazinga e-lumen ahlukene, ungabhekisela kudatha elandelayo: ukukhempa ebusuku: cishe i-lumen eyi-100 yokuhamba ebusuku, ukuwela (kucatshangelwa izinguquko zesimo sezulu njengemvula nenkungu) : 200 ~ 500 lumen mayelana ukugijima komkhondo noma eminye imijaho yasebusuku: 500 ~ 1000 lumen ukusesha ebusuku kochwepheshe kanye nokuhlenga: ngaphezu kwe-lumen eyi-1000
Qaphela lapho usebenzisaizibani zangaphambili(ikakhulukazi lawo ane-lumens ephezulu), ungawakhombi emehlweni abantu.Ukukhanya okukhanyayo kakhulu kungabangela umonakalo emehlweni abantu.
