    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.

  • Patent number: 9204511
    Abstract: A lighting apparatus includes a chopper circuit and a control circuit that controls the chopper circuit. The control circuit includes a determining unit that determines a duty ratio of a dimming signal, and an output control unit that outputs a drive signal. The control circuit outputs a drive signal from the output control unit according to a result of a determination by the determining unit and causes the solid state light-emitting element to be lighted in a normal mode. In the charging mode, the control circuit sets an average value of a current flowing through an inductor to be higher than in the normal mode and charges a smoothing capacitor until a voltage across the smoothing capacitor reaches a prescribed voltage. When power is supplied, the control circuit charges the smoothing capacitor in the charging mode and subsequently lights the solid state light-emitting element in the normal mode.
