Luminous intensity measures the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle. It quantifies how bright a light source appears to the human eye, playing a crucial role in lighting design, display technologies, and visual ergonomics.
Example Conversions:
- 1 candela = 1 lumen per steradian
- 800 lumens ≈ 800 candelas (for a point light source)
