Abstract
Abstract An improved light emitting diode (LED) package structure for an LED lighting device comprises a reflector having a bowl-shaped reflecting surface formed by a pressing technique. A stand member extends from the center of the reflecting surface to the focus point of the reflector to support an LED die thereon. This arrangement allows the reflecting surface to extend toward the center thereof in order to increase the reflecting surface area and thus increasing the luminance of the LED display.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A light emitting diode display, comprising: a printed circuit board having a plurality of through-holes formed therein, said through-holes having electrically conductive materials placed on an inner surface of said through-holes; a plurality of electrically conductive members, each of said electrically conductive members being fixed in and electrically connected with a corresponding one of said plurality of through-holes of said printed circuit board and providing electrical connection for both sides of said printed circuit board; an end of each of said electrically conductive members having a bowl-shaped recess formed thereon defining a bowl-shaped reflecting surface; said bowl-shaped reflecting surface having a bottom center and a focus point along an optical axis of said bowl-shaped reflecting surface; a light emitting diode die being mounted on the bottom center of said bowl-shaped reflecting surface; and a conductive lead being electrically connected between the light emitting diode die and an electrically opposite polarity zone of the printed circuit board.
Claim 2
Dependent Claim
156 words
