  • Lateral edge-lit light-guide optics for LED lighting
    Patent number: 11852858
    Abstract: A LED lighting system includes a power supply, a LED controller, and a light guide plate having a top, a bottom, and an edge. A printed circuit board connected to the power supply is positioned at least partially under the bottom of the light guide plate. At least one surface-emitting LED is positioned on the printed circuit board adjacent to the light guide plate and directed to emit light vertically. A partially transmissive reflector is attached to extend between the top of the edge of the light guide plate and the printed circuit board to direct vertically emitted light from the at least one surface-emitting LED into the edge of the light guide plate.
