LED package and method of making the same

A LED package, comprising:

• a plastic body structured to include integrally formed an upper portion and a lower portion and have an array of holes that penetrate through the lower portion of the plastic body;
• a metal contact formed on the plastic body to be interposed between the upper portion and the lower portion and cover the holes at one side of the holes;
• a LED mounted to the metal contact at a location that spatially overlaps with the holes;
• and
• thermally conductive channels made of a thermal conductive material that is filled in the holes in contact with the metal contact and each thermally conductive channel extending to an opening of each respective hole to transfer heat from the LED through the metal contact to dissipate the heat at the openings of the holes.

A light-emitting diode (LED) device, comprising:

• a contiguous injection molded plastic body structured to include a bottom portion configured to have a through hole and a top portion contiguously extended from the bottom portion upward to adopt to the through hole, wherein the contiguous injection molded plastic body is made of a white injection molded plastic material to facilitate light output efficiency;
• a metal contact layer formed on the contiguous injection molded plastic body to cover top, side and part of bottom surfaces of the bottom portion while covering the top opening of the through hole to leave the bottom opening of the through hole open, the metal contact layer further configured to expose the top portion of the contiguous injection molded plastic body, and the metal contact layer being polished to provide better heat transfer performance and including an optically reflective coating containing silver or gold to facilitate wire bonding and to improve light out efficiency;
• a LED device mounted to the metal contact at a location that spatially overlaps with the through hole;
• a thermally conductive stud located in the through hole to include a first stud end in contact with the metal contact layer at the top opening of the through hole to receive heat from the LED device and a second stud end protruding outside the bottom opening of the through hole to release the received heat;
• and
• an electrically conductive wire bonded to the LED device and the optically reflective coating of the metal contact layer for energize the LED device to emit light.
