  • Luminaire System with Thermal Chimney Effect
    Publication number: 20080285265
    Abstract: A luminaire system having an elongated throughway utilizing a thermal chimney effect. The thermal chimney effect within the throughway circulates air to remove heat generated from the electrical components of the system. Dissipating heat into the throughway from the electrical components can increase the life expectancy of the lamp and the output of the lamp. The electrical components of the system being entirely sealed and isolated from the throughway results in a permanent air, dust, and water tight seal. The permanent seal can minimize damage to the electrical components of the system as well as prevent the build up of moisture and dust within these sealed components.

  • Pendent style luminaire split design
    Patent number: 7422350
    Abstract: The pendent style luminaire split design incorporates generally a housing split into sections, a first section of the housing is attached to the top member located at the mounting arm while the second section of the housing is attached to the lens frame. The second section swings about a hinge between the first section and the lens frame. In the open position of the luminaire, the design allows for the convenience of “hands free” maintenance of both the lamp and the electrical component assembly of the luminaire at the same time. A sealed optical chamber is created, since neither the lens nor lens frame is needed to be separated from the reflector to gain access to the lamp.

  • Efficient fluorescent lighting system
    Patent number: RE40619
    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.
