Abstract:
1. A light emitting diode (LED) package, comprising: a package body comprising a substrate comprising a first side, a second side, and an opening, the first and second sides being opposite sides of the substrate; a metallic portion arranged in the opening, the metallic portion being exposed at the second side of the substrate; a first lead electrode and a second lead electrode spaced apart from each other and the metallic portion; and a light emitting device arranged on the metallic portion and electrically connected to the first lead electrode and the second lead electrode, wherein the entire first side of the substrate is substantially flat, wherein the light emitting device is arranged on a first side of the metallic portion, and the first lead electrode and the second lead electrode are arranged on the second side of the substrate, wherein the first side of the metallic portion is at an opposite side of the second side of the substrate, wherein the LED package is configured to be driven by an alternating current (AC) and by a voltage higher than that for driving one light emitting diode, wherein a second side of the metallic portion is substantially flush with the second side of the substrate, the second side of the metallic portion being an opposite side than the first side of the metallic potion, wherein inside surfaces of each of the first lead electrode and the second lead electrode only directly contact the substrate, wherein at least a portion of the first side of the metallic portion is substantially flush with the entire first side of the substrate, wherein the metallic portion consists of a homogenous metallic material structure, and wherein the substrate is an insulating substrate, and the metallic portion consisting of the homogenous metallic material structure directly contacts the insulating substrate in the opening.
