  • Patent number: 11419192
    Abstract: A lighting apparatus includes a light source, a detector and a driver. The light source includes a first set of LED modules and a second set of LED modules. The first set of LED modules and the second set of LED modules emit lights with different color temperatures. The detector is used for detecting an operation pattern corresponding to one of a plurality of operation modes. The operation pattern is transmitted from an operation on a wall switch electrically connected to the lighting apparatus. The driver generates a first current to the first set of LED modules and a second current to the second set of LED modules based on the operation mode associated with the detected operation pattern. The operation mode corresponding to both a corresponding luminance level and a corresponding color temperature at the same time.
