Lighting apparatus

A lighting apparatus, comprising:

• an external controller for converting an external signal of an 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 continuous switch for a user to select a continuous value from a range;
• a first LED module of a light source set;
• a second LED module of a light source, 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;
• a manual switch for selecting a color temperature setting;
• an internal controller;
• a light housing for disposing the light source set, the rectifier, the power switch, the internal controller and the manual switch, wherein the internal controller is coupled to the manual switch for converting the color temperature setting to a color temperature control signal;
• and
• 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.
