1. A lighting apparatus coupled to an external wall switch, comprising:
an external controller for converting an external signal of the external wall switch to a light intensity signal, wherein the external controller is coupled to the external wall switch, wherein the wall switch is a switch for a user to select a value;
a first LED module of a light source set;
a second LED module of the light source set, wherein the first LED module and the second LED module emit lights of different color temperatures;
a rectifier for converting an AC power to a DC power;
a power switch coupled to the rectifier for generating a driving current corresponding to the light intensity signal;
an internal controller for receiving a color temperature setting;
a light housing for disposing the light source set, the rectifier, the power switch, the internal controller and a manual switch, wherein the internal controller is coupled to the manual switch for converting the color temperature setting to a color temperature control signal;
an allocation module for dividing the driving current to the first LED module and the second LED module according to the color temperature control signal, wherein the power switch receives the color temperature control signal and further adjusts the driving current according to the color temperature control signal, wherein an overall light intensity of the lighting apparatus is adjusted higher in a first color temperature than in a second color temperature, wherein the first color temperature is higher than the second color temperature; and
an intensity switch disposed on the light housing for a user to select a default light intensity in a continuous range, wherein the power switch ignores the default light intensity when the external controller transmits the continuous value to the power switch, wherein the power switch has a rule module for determining a priority between the continuous value and the default light intensity.
