luminous exposure
light exposure (obsolete) (at a point of a surface, for a given duration)
quotient of dQv, quantity of light incident on an element of the surface containing the point over the given duration, by the area dA of that element

Equivalent definition. Time integral of Ev, illuminance at the given point, over the given duration Δt
