Abstract: A dynamic light control method for controlling at least one adjustable illumination parameter at a target location has been suggested. The method comprises setting the value of at least one adjustable illumination parameter at a first predetermined level, maintaining the value of the at least one adjustable illumination parameter at the first predetermined level for a first predetermined time period, varying the value of the at least one adjustable illumination parameter from the first predetermined level to a second predetermined level, maintaining the value of the at least one adjustable illumination parameter at the second level for a second predetermined time period, and varying the value of the at least one adjustable illumination parameter from the second level to a third predetermined level, wherein the varying the at least one adjustable illumination parameter comprises monotonously varying the at least one adjustable illumination parameter with a predefined maximum variation rate.
