Patent abstract
A lighting apparatus comprises the following elements. A first set of light emitting diode module includes a variety of light emitting diode elements, wherein different types of light emitting diode elements have different color temperature characteristics. A driving circuit supplies power to the first set of light emitting diode module, such that the plurality of light emitting diode elements emit light. Moreover, the driving circuit may supply currents with different total values, and the optical characteristics of the first set of light emitting diode module change accordingly, so as to change color temperatures.
