Driving circuit and method for reducing operating temperature of led package

A driving circuit for driving one or multiple LED chip sets, said driving circuit comprising:

• a power converting circuit for receiving an input power and converting said input power into a regulated output voltage or current required for illuminating said one or multiple LED chip sets;
• and
• a waveform generator electrically connected to said power converting circuit and said one or multiple LED chip sets for generating a control wave with positive and negative voltages, wherein said one or multiple LED chip sets in an alternate lighting manner in response to said positive and negative voltages of said control wave.

A method of reducing the operating temperature of a LED package including one or multiple LED chip sets, said method comprising steps of:

• providing a driving circuit and electrically connecting said driving circuit with said one or multiple LED chip sets;
• and
• driving and controlling said one or multiple LED chip sets by said driving circuit to emit light in said alternate lighting manner or a combined simultaneous/alternate lighting manner so as to reduce the operating temperatures of said one or multiple LED chip sets.
