  • Integral troffer motion detector
    Patent number: 9163814
    Abstract: A sensor system (20) electrically connected to and controlling at least one recessed luminaire (30). The sensor system housing (22) is externally connected to the luminaire (30) and includes a flexible member (50) projecting therefrom. The flexible member (50) supports detection electronics spaced from the sensor system housing (22) or the coupled light fixture and sensor system housings (32, 22). The flexible member (50) allows a sensor (52) to be horizontally and vertically positioned relative to the sensor system housing (22).

  • Virtual direct and indirect suspended lighting fixture
    Patent number: 8002446
    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.

  • Efficiency fluorescent lighting system
    Patent number: 6817732
    Abstract: An improved efficiency fluorescent lighting system is described. The system utilizes reduced rows of fluorescent luminaires which are spaced much further apart than traditional spacing. The luminaires used in the system of the present invention have increased light output of each luminaire by up to fifty percent through a combination of use of a high efficiency lamp producing about 3250 lumens, an electronic dimming ballast having a ballast factor of about 1.2 and a luminaire having a spacing to mounting height ratio of at least 1.5.
