Abstract
An LED lamp includes two LED modules and a control module. The LED modules emit lights with different color temperatures. The lights are mixed in the LED lamp and form an output light with another color temperature. The control module controls the brightness levels of the lights emitted from the two LED modules to thereby control the color temperature of the output light.
