Abstract: A louver to distribute light emitted by a light fixture. A frame is formed integrally with the exterior housing of the louver. The integral frame eliminates the need for a separate louver door frame which has traditionally been used to mount a louver within a light fixture. The exterior housing may be formed from end blades and side stringers. A flange may provide additional support for the integral frame of the louver. Mounting means may be positioned and oriented on the end blades of the exterior of the housing. The mounting means may include hinges that interact with the light fixture housing or other mounting apparatuses. Additional securing means may be associated with the end blades of the louver for securing the louver in the proper orientation relative to the light fixture housing.

Abstract: Retrofit systems for replacing the outdated components of an existing light fixture. The retrofit systems may utilize the previously installed housing of the existing light fixture. The retrofit systems include brackets that are positioned on the ends of the housing. The positioning of the brackets is based off of the ceiling, t-grid, or the bottom of the housing. Lamp sockets with associated lamps, an optional ballast tray with associated ballast, reflector(s), lamps, and a shielding mechanism are all mounted on, and their position in the housing dictated by, the mounting brackets. Thus, regardless of the depth of the housing, the lamps are positioned a uniform distance from the ceiling opening to create consistent light distribution. Moreover, because these components are not directly attached to the housing, their dimensions need not precisely match those of the housing. Rather, the retrofit system can be installed in housings of varying sizes and shapes.

Abstract: A louver assembly is disclosed for use in an overhead lighting system. The louver assembly comprises a series of thin, lightweight stringers and blade ribs arranged perpendicular to one another such that the respective side surfaces of the respective stringers are positioned at an acute angle with respect to a ceiling plane and the reflective faces of the blade ribs are positioned substantially transverse with respect to the ceiling plane.

Abstract: The present invention provides systems and apparatuses for dynamically controlling the operational modes of a single luminaire or a group of networked luminaires configured to deliver an illumination pattern having a decorative colored glow surrounding a central region of substantially uniform brightness. A control module for the luminaire is configured to drive three dimmable fluorescent ballasts, as well as a LED module. A variety of operational modes including different schemes for color mixing and color cycle control can be selected by a user and implemented by a microcontroller. A group of luminaires is connected in a standard communication protocol-based master-slave configuration, where the slave units respond to commands received from the master unit, and the last slave unit automatically engages terminating and biasing resistors for proper operation of the network.
