    摘要: A generally planar illumination, display, or backlighting device is disclosed, including a generally planar arrangement of side emitting light emitting diode (LED) devices generating side emitted illumination, and a generally planar arrangement of wavelength conversion elements arranged coplanar with the generally planar arrangement of side emitting light emitting diode (LED) devices. The wavelength conversion elements are interspersed amongst the side emitting LED devices and configured to wavelength convert the side emitted illumination generated by the side emitting LED devices. A display device using such a generally planar illumination device is also disclosed, in which a liquid crystal display (LCD) panel is backlit by the generally planar illumination device.

    摘要: A lighting apparatus (10) includes a wave guide (14) formed from a translucent material. The wave guide has a top surface (30), a bottom surface (32) that has a pre-defined curvature, and at least one side surface (34) that receives light (40) injected therein. A plurality of microstructures (36) is arranged on selected areas of the bottom surface (32) of the wave guide (14). The plurality of microstructures (36) cooperates with the pre-defined curvature of the bottom surface (32) to scatter at least a portion of the light (40) injected into the at least one side surface (34). The scattered light (42) exits the wave guide (14) through the top surface (30). At least one light emitting diode (16) injects light (40) into the at least one side surface (34) of the wave guide (14). The scattered light (42) that exits the wave guide (14) forms at least one symbol viewable by an associated observer.
