Abstract:
1. A package structure for light-emitting diodes (LEDs), comprising: a substrate having an inner portion and at least one outer portion; a plurality of heat-conducting members disposed in the substrate, wherein some of the heat-conducting members located in the inner portion is capable of dissipating more heat than the other heat-conducting members located in the outer portion; a heat-dissipating structure disposed on the substrate; a pair of electrodes having a positive terminal and a negative terminal and disposed on the substrate; and a plurality of LED chips disposed on the heat-dissipating structure and electrically connected to the positive terminal and the negative terminal, the plurality of LED chips having at least one first LED chip and at least one second LED chip, the first LED chip disposed above the inner portion, the second LED chip disposed above the outer portion, wherein the plurality of heat-conducting members is capable of reducing the temperature difference between the first LED chip and the second LED chip when the first and second LED chips are emitted; wherein a heat conduction path is substantially constructed by the heat-dissipating structure and the plurality of heat-conducting members, an electrical conduction path is constructed by the positive terminal and the negative terminal, thus the heat conduction path and the electrical conduction path are separated from each other.
