Specialty Definition: COSINE LAW OF ILLUMINATION

DomainDefinition

Aerospace

A purely geometric relationship between the illuminance of a surface and the angle of incidence of the illuminating rays. Mathematically, the illuminance I of the surface illuminated by a beam of flux density F incident at angle is I = F cosThe marked latitudinal variation in insolation on the earth is largely a consequence of this simple relationship. Compare Lambert law. (references)
