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.
