  • Patent number: 10677980
    Abstract: Interlocking light emitting diode (“LED”) light guide tiles are disclosed. The tiles have interlocking edge features that provide physical interlock fitting between tiles and present a continuous appearance, both in an “on,” where LEDs are powered on and emitting light state and an “off” state, where LEDs are powered off and not emitting light. The LED light guide tiles interface with LEDs (housed in or embodied as integrated circuit LED packages) to output light through the surfaces of the light guide. The interlocking edge features of the light guide tiles are shaped to obscure or block an image of the LED packages from being seen by observers looking at the light guide tiles. Light guide tile assemblies or installations can be easily formed out of interchangeable tiles with little or no requirement for relative directional alignment of the tiles.
