The luminous intensity of a light source is defined as the luminous flux emitted per unit solid angle.
It is calculated as:
\(I={ϕ\over Ω}\)
where, I = Luminous intensity
ϕ = Luminous Flux
Ω = Solid angle
If a source emits 10 lumens per steradian uniformly in all directions, that directly defines its luminous intensity:.
\(I={10\space lumens\over 1\space steradian}\)
I = 10 candela
