Title: MULTIPLE LED LIGHT SOURCE LENS DESIGN IN AN INTEGRATED PACKAGE
Abstract:
Light emitting diode (LED) packages (40) and LED displays utilizing the LED packages (40) are disclosed. LED packages (40) can have a cavity (42) with emitters (44) arranged in close proximity to approximate a point light source, with each of the packages (40) emitting a color combination of light from the emitters (44). The LED packages (40) are arranged with an encapsulant or lens (202, 222) over the cavity (42) that shapes the LED package (40) emission to a wide angle or pitch. An LED package (40) comprises a cavity (42) with a plurality LEDs. The LED package (40) also comprises a lens (202, 222) over the cavity (42) to shape the emission of the LEDs to a wider angle along an axis compared to emission of the LEDs without the lens (202, 222). The LEDs are individually controllable, with the LED package (40) emitting different color combinations of emission from the LEDs. An LED display comprises a plurality of LED packages (40), at least some having a cavity (42) with a plurality of LEDs. Each of the packages (40) comprises a lens (202, 222) over each cavity (42) to produce an emission of the LEDs that has a wider angle compared to the emission without the lens (202, 222). The LED packages (40) are mounted within the display to generate a wide angle image.
