Abstract
A lighting apparatus includes a power supply unit and a control unit configured to control the power supply unit. The control unit determines, at a time of activation of the lighting apparatus, a first color temperature of the load at an initial stage of lighting based on a command value. Thereafter, the control unit controls the power supply unit such that the light quantity and the color temperature of the load change according to a second output characteristic during a period in which the color temperature of the load changes from the first color temperature to a second color temperature. The second color temperature is a color temperature, in the first output characteristic, corresponding to the command value. A correspondence relationship between a plurality of light quantities and a plurality of color temperatures defined by the second output characteristic is different from that of the first output characteristic.
