LED heat-radiating substrate and method for making the same

摘要

An LED heat-radiating substrate and a method for making the same are proposed. The LED heat-radiating substrate has a low expansion layer body and two high thermal conductivity layer bodies formed at its two sides. Through mutual connection and containment of these layer bodies, the requirements of high heat-radiating effect and low expansion can be met. An LED structure can be arranged on the heat-radiating substrate to accomplish a high heat-radiating effect. Moreover, damage to the LED structure due to thermal expansion of the heat-radiating substrate can be avoided.
