The law of Lamberts Cosine states that the radiant energy from any small surface area dA in any direction θ associative to the surface normal is proportional to the Cos θ. In case of diffused reflection the source is directional however reflection is uniform. When I is the intensity, then according to the law of Lamberts Cosine,
   
Intensity -> (Proportional) Cos θ
