Component embedded printed circuit board

1. An optical component embedded printed circuit board comprising:

a metal core having at least one cavity formed therein;

a first insulation layer stacked on a lower side of the metal core, the first insulation layer having at least one first region exposed by the at least one cavity and a second region being in contact with the metal core;

an optical component embedded in the cavity to be disposed on the first region of the first insulating layer;

first and second vias formed in the first and second regions of the first insulating layer, respectively;

a second insulation layer stacked on an upper side of the metal core;

a circuit pattern formed on a lower surface of the first insulation layer and electrically connected with the optical component through the first via and thermally connected to the metal core through the second via; and

an external component mounted on the circuit pattern formed on the lower surface of the first insulation.

2. The optical component embedded printed circuit board of claim 1 , wherein the optical component is an LED, and

at least a portion of the second insulation layer over the LED has a curved surface about the LED.

3. The optical component embedded printed circuit board of claim 1 , wherein the optical component is an LED, and

at least a portion of the second insulation layer over the LED has roughness.

4. The optical component embedded printed circuit board of claim 1 , wherein the optical component is an image sensor, and

an infrared filter layer is further stacked on the second insulation layer.

5. The optical component embedded printed circuit board of claim 1 , wherein the second insulation layer has a circuit pattern formed thereon.
