摘要： This invention provides an illumination apparatus and an illumination method. The illumination apparatus comprises: a first light source for illuminating a first area; a second light source for illuminating a second area; a first measuring unit for measuring the illuminance of the first area; a second measuring unit for measuring the illuminance of the second area; and an adjusting unit for adjusting at least one of the first light source and the second light source to make the contrast ratio of the measured illuminance of the first area to the measured illuminance of the second area change gradually from a first predefined value to a second predefined value lower than the first predefined value during a first predefined duration. In this way, the relative higher contrast ratio (i.e. the first predefined value) enables the users to improve their work efficiency and the relative lower contrast ratio (i.e. the second predefined value) allows the users' eyes to be comfortable. In addition, because the contrast ratio changes gradually, the users' attention will not be distracted and the users' eyes will remain comfortable when the contrast ratio changes.
