Cara Menghitung Luminosity Converter
learn.whatIsHeading
Luminosity (light intensity) converters translate between candela, lumens, lux, and foot-candles for lighting calculations.
Rumus
1 lumen = 1 cd × solid angle (steradians)
Panduan Langkah demi Langkah
- 11 candela (cd) = standard light intensity unit
- 21 lumen = 1 cd × solid angle (steradians)
- 31 lux = 1 lumen/m²; 1 foot-candle = 10.764 lux
Contoh Terpecahkan
Masukan
Desk lamp 500 lumens, distributed to 2 m² area
Hasil
Illumination ≈ 250 lux (good task lighting)
Typical office ~300-500 lux
Kesalahan Umum yang Harus Dihindari
- ✕Confusing lux with lumens (very different meanings)
- ✕Neglecting distance and inverse square law
Pertanyaan yang sering diajukan
Why separate lux from lumens?
Lumens = total light output (independent of area); lux = intensity at surface (lumens/area).
How does distance affect illumination?
Inverse square law: doubling distance reduces illumination 4×. Affects lamp placement.
