Abstract: A package structure for solid-state lighting with low thermal resistance is revealed. A solid-state light is set on a circuit board with high thermal conductivity. A connection layer is used for binding the circuit board with high thermal conductivity and the heat sink substrate. A first attachment layer is set between the heat sink substrate and the connection layer; and a second attachment is set between the connection layer and the circuit board with high thermal conductivity. The connection layer is made of metals or metallic composite materials with high heat dissipation and low thermal expansion coefficients. Thereby, the thermal resistance is lower than the structures according to the prior art. In addition, the thermal stress produced between the heat sink substrate and the circuit board with high thermal conductivity can be buffered by the connection layer for increasing lifetime of the package structure according to the present invention.
