Illumination apparatus including a source of artificial light and shutters for totally concealing the source of light during a first amount of time to simulate night conditions, for gradually exposing increasingly larger portions of the source of artificial light during a second amount of time to simulate dawn and morning conditions, for constantly exposing a portion of the source of artificial light during a third amount of time to simulate mid-day condition, and for gradually concealing an increasingly larger portion of the source of artificial light during a fourth amount of time to simulate afternoon and dusk conditions.
