Abstract: A light-emitting diode (LED) module includes a substrate, an LED, a first encapsulation element and a second light-pervious encapsulation element. The substrate has a first surface, a second surface, a circuit layer and an opening, wherein the opening penetrates through the first surface and the second surface, and the circuit layer includes at least one first conductive contact disposed on the first surface. The LED is disposed in the opening and is electrically connected to the first conductive contact. The first encapsulation element and the second light-pervious encapsulation element are respectively disposed on the first surface and the second surface, for encapsulating the LED and the first conductive contact. The aforementioned LED module may output light from the back of the LED, thereby improving the light output efficiency of the LED module. A manufacturing method of the aforementioned LED module is also herein disclosed.

Abstract: An LED lamp module includes a heat sink element having one-piece form; a circuit substrate affixed onto the heat sink element, wherein the substrate has at least an opening exposing the heat sink element, and has an area smaller than that of the heat sink element; a plurality of LED chips mounted on the exposed portion of the heat sink element and electrically connected to the circuit substrate; and a light transparent package material, encapsulating the plurality of LED chips, wherein the heat sink element includes a uniform temperature plate or a plate including at least a vacuum cavity, and an extension part extending laterally from the plate and turned to surround the plurality of LED chips, forming a secondary optical structure. A fabrication method for the LED lamp module is also disclosed. Existing fabrication process is simplified and the cost is lowered with increased heat dissipation effect.

Abstract: The present invention discloses a package substrate comprising an insulative carrier having a through-hole penetrating the top and bottom surfaces thereof; at least one first and second conductive layers comprising circuits respectively formed on the top and bottom surfaces and covering an opening of the through-hole; a conductive element set in the through-hole for electrically connecting the first and second conductive layers; a first metal layer formed on the first and/or the second conductive layer; and at least one chip receiving bay formed by removing a portion of the carrier from the upper to the lower surfaces until the second conductive layer is exposed for accommodating at least one chip therein on the exposed second conductive layer. The package structure has a reduced overall thickness and an enhanced heat-dissipation effect for the chip and prevents from humidity penetration. A manufacturing method for the package structure is also disclosed.
