Abstract
A direct and indirect suspended component light fixture is described herein. The light engine of the fixture is recessed within a ceiling and contains a plurality of linear fluorescent lamps substantially surrounded by an ellipsoidal reflector. The ellipsoidal reflector reflect light downward through a light output region to a suspended diffuser, the suspended diffuser acting as both a provider of direct and indirect light to generate smooth and even illumination both in the indirect and direct light components.
