A luminaire system having a lamp compartment and sterilization compartment permitting both illumination and the sterilizing of airborne bacteria. The sterilization compartment has one or more germicidal lamps to sterilize airborne bacteria when air is circulated through the luminaire system. The lamp compartment has one or more lamps to illuminate the desired outside environment away from the system.

Air purifying luminaire

A sensor system () electrically connected to and controlling at least one recessed luminaire (). The sensor system housing () is externally connected to the luminaire () and includes a flexible member () projecting therefrom. The flexible member () supports detection electronics spaced from the sensor system housing () or the coupled light fixture and sensor system housings (). The flexible member () allows a sensor () to be horizontally and vertically positioned relative to the sensor system housing ().

Integral troffer motion detector

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.

Virtual direct and indirect suspended lighting fixture

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.

Efficient fluorescent lighting system

Luminaire lens

Luminaire lens and baffle

In order to provide efficient and uniform up and down lighting an elongated luminaire comprises an elongated concave primary down light reflector, a pair of secondary down light reflectors having slots approximately horizontal with a lamp, and a pair of up light reflectors attached to the secondary down light reflectors opposite the lamp and horizontal with the lamp and slots such that an efficient and uniform illumination across the ceiling surface and the floor area is accomplished.
