Base structure of LED chips

The utility model relates to a substrate structural body of an LED core. The substrate structural body of the utility model is provided with a backing, a cushioning layer and a reflective mirror layer, wherein the cushioning layer is arranged on the backing, and the reflective mirror layer is arranged on the cushioning layer; the reflective mirror layer is composed of a metal substrate layer provided with a micropore array and a metal reflective layer deposited on the surface of the metal substrate layer and in the micropore array. An LED made of substrate structural body of the utility model has little leakage loss and total reflection loss during operation, which results in the high light emitting efficiency of the LED.
