Title: LED LIGHTING FIXTURE WITH A LIGHT EMITTING WAVEGUIDE RESEMBLING A LAMP SHADE
Abstract:
The invention is the design of a lighting waveguide and its assembly in an LED lighting fixture. LED waveguide technology offers a novel approach to the design of a lighting fixture that still retains a typical appearance of a lamp shade and lighting fixture. The invention is a nominally transparent plastic or glass waveguide fashioned in the shape of a lamp shade with a slot at one side that defines a gap between two edges or ends of the side of the waveguide, and possess perturbations on the surface of the waveguide to facilitate the extraction of light to provide usable light from the lighting fixture. An LED PCB board with side-mounted LEDs is mounted to the lighting fixture between the slot in the waveguide such that the light emitting surfaces of the LEDs are proximal to and face towards the edges of the waveguide, Illuminating the waveguide and providing light from the light fixture by means of the perturbations that provide a light extracting means.
