摘要： 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.

摘要： An LED circuit with color temperature adjustment comprises a first LED string, a resistor, and a second LED string. The first LED string has a first color temperature. The resistor is connected in series with the first string. The second LED string has a second color temperature. The first LED string is connected in parallel with the second LED string. The second color temperature is higher than the first color temperature. The integrated color temperature of the first LED string and the second LED string increases when the total current of the first LED string and the second LED string increases. The present disclosure not only can provide an LED circuit with color temperature adjustment, but also can provide an LED circuit which can adjust the color temperature by the combinations of the LED strings connected in parallel or series.

摘要： A LED sensing light driving circuit includes a rectifying filter circuit, a buck power-supplying circuit, a constant current driving circuit, a sensing signal generating circuit, and a hysteresis comparator circuit. The rectifying filter circuit has a DC output terminal supplies power to the sensing signal generating circuit and the hysteresis comparator circuit via the buck power-supplying circuit. The sensing signal generating circuit reduces a voltage at a first input terminal of the hysteresis comparator circuit in response to increase or decrease of surrounding luminance.
