The invention provides an illumination apparatus and a method of generating light by the illumination apparatus. The illumination apparatus comprises a light generation unit, configured to generate light having a color temperature in the range of [a first color temperature, a second color temperature]; and a controller, configured to control the light generation unit to generate light having a color temperature changing from a third color temperature to a fourth color temperature over time, wherein the third and the fourth color temperatures are in the range of [the first color temperature, the second color temperature]. The illumination apparatus of the invention could generate light having a changing color temperature over time, for example a color temperature changing from a less preferred color temperature to a preferred color temperature. When the user reads under light having a color temperature changing from a less preferred color temperature to a preferred color temperature, the accommodation error of the eyes of the user can be reduced. |
