Abstract: The invention offers an improvement in lighting control systems by providing a simplified power switching control system (i.e., using direct AC line voltage or DC current power switches instead of low voltage switches that control higher-current-capable relays) that controls the power to the power supplies that drive the light producing devices in a plurality of luminaires or lighting fixtures in a given installation. The lighting control system facilitates multiple modes of lighting configurations while requiring fewer switches that the prior art and also being easier to operate. The system supports the simultaneous use of multiple lighting technologies. Other embodiments showing extensions to the invention are also disclosed.

Abstract: The invention provides an improvement in suspendable structures and assemblies such as linear lighting fixtures/luminaires that are intended to be suspended from ceilings or other such structures. The housings of the assemblies are designed to include at least one structural member with prestressing in at least along a major longitudinal axis over at least a portion of the length of the member. Once the structural member is incorporated into the housing and overall assembly, the housing and/or assembly is substantially planar and uniform once the assembly is suspended, making the assembly both stronger and more aesthetically appealing. Other embodiments showing extensions to the invention are also disclosed.
