摘要： LED devices includes a lead frame having a reflector cup with a round bottom surface and a wall surface having a variable inclination with respect to the bottom surface and defining an opening at an upper end thereof. An LED is mounted on the bottom surface of the reflector cup, and an LED module includes first and second LED device that emit different colors. The first and second LED devices have substantially matched far field patterns in a first and second direction, where a first viewing angle in the first direction is less than about 99°.

摘要： An LED package and a lead frame include a reflector cup having a bottom surface with an LED asymmetrically positioned on the bottom surface and a wall surface inclined relative to the bottom surface and defining an opening at an upper end thereof. The bottom surface of the reflector cup has a first axial dimension along a first axis and a second axial dimension along a second axis, orthogonal to the first axis. A display having an asymmetrical FFP and asymmetrical screen curve includes an array of the LED modules including a plurality of LED packages. At least some of the LED packages include a dome-shaped lens asymmetrically positioned with respect to a geometric center of the bottom surface of the reflector cup.
