Abstract
Disclosed are a heat dissipative substrate for a light-emitting diode and a manufacturing method thereof. The heat dissipative substrate comprises a low expansion layer and two high thermal conductivity layers disposed on the opposite surfaces of the low expansion layer, these layers are bonded together so as to impose physical constraints on each other to thereby realize high heat dissipation rate and low expansion rate. The light-emitting diode is mounted on the heat dissipative substrate to effect efficient heat dissipation and to protect the structure of the light-emitting diode from the damage caused by the thermal expansion of the heat dissipative substrate.
