Abstract
A lighting apparatus of adjustable color temperature including a luminescent source, a controller and a detector is proposed. The luminescent source is configured to provide an illumination source. The controller is coupled to the luminescent source. The controller is configured to adjust a color temperature of the illumination source according to at least one of global and local color temperatures. The detector is coupled to the controller. The detector is configured to detect a color temperature of a location of the lighting apparatus of adjustable color temperature, so as to provide the local color temperature to the controller. The controller performs a weighting operation for the global and local color temperatures to obtain an operation result for adjusting the color temperature of the illumination source. A method for adjusting color temperature of a lighting apparatus of adjustable color temperature is also proposed.
