Abstract
The present invention relates to a package structure for light-emitting diodes (LEDs). The package structure includes a substrate, a heat-dissipating structure disposed on the substrate, and a plurality of LED chips uniformly disposed on the heat-dissipating structure. The heat-dissipating structure has a central portion and at least one peripheral portion surrounding thereof. The central portion is capable of dissipating more heat than the peripheral portion. Thus, the temperature difference between the LED chips disposed on the central portion and the LED chips disposed on the peripheral portion can be reduced.
