The present invention relates to a driving circuit for driving one or multiple LED chip sets. The driving circuit includes a power converting circuit, one or multiple switching elements, and a controller. The power converting circuit is electrically connected to the one or multiple LED chip sets for receiving an input power and converting the input power into a regulated output voltage or current required for illuminating the one or multiple LED chip sets. The one or multiple switching elements electrically connected to the one or multiple LED chip sets. The controller is electrically connected to the switching elements for controlling alternate or combined simultaneous/alternate switching on/off statuses of the one or multiple switching elements, so that the one or multiple LED chip sets emit light in an alternate lighting manner or a combined simultaneous/alternate lighting manner to reduce the operating temperatures of the one or multiple LED chip sets.
