Abstract: A light guide plate (12) has a light incidence surface (121) for receiving light, a light emitting surface (123) for emitting light, and a bottom surface (122). The bottom surface has a plurality of diffusion elements (124) arranged thereat. Each diffusion element defines a diffraction grating unit (125) therein. A grating direction of each diffraction grating unit is substantially perpendicular to a main direction of light beams received by the diffraction grating unit. Areas of the diffraction grating units progressively increase with increasing distance away from the light incidence surface. Diffractive capabilities of the diffraction grating units progressively increase with increasing distance away from the light incidence surface. These features improve the overall efficiency of utilization of light, and enable the light emitting surface to output highly uniform light.

Abstract: A lighting fixture where the lighting fixture uses inductive lighting technology or self ballasting lighting elements with one or a plethora of efficient light elements. The lighting fixture is used where high bay or low bay lighting may be used, but incorporates multiple light sources to provide an equivalent light intensity. The multiple light sources can be inductive or multiple fluorescent, LED or other efficient light sources to provide a less expensive cost of operation and installation. The higher efficiency lights could be standard socket type fluorescent or inductive light bulbs that are easily available. The higher efficiency lights will also create less heat that will further reduce the air conditioning or cooling costs for the building. An integrated ballast box with reflector dome retainer is also shown for use with inductive or other lighting that further includes a retaining mechanism for the dome.
