Abstract
Lighting fixtures are described utilizing a plurality of light sources, or light engines, which are mounted together in a modular fashion in the light fixture opening. In some embodiments, the plurality of light sources can comprise lighting panels that together form the overall fixture light source. The present invention is particularly applicable to troffer-style lighting fixtures that can be arranged with a plurality of lighting panels arranged in the troffer opening to illuminate the space below the troffer. Embodiments of the present invention can also utilize solid state light sources for the lighting panels, with some embodiments utilizing light emitting diodes (LEDs).
