Abstract: This disclosure relates to LED based lighting systems, such as surface mounted lighting systems and lighting systems that can connected to an existing grid structure. These lighting systems can be utilized in many settings, for example, as primary lighting systems for a commercial building and for retrofit lighting improvement purposes. Devices according to the present disclosure provide lighting systems capable of mounting to an existing surface, such as a T-bar ceiling structure. These devices can further comprise modular elements which facilitate connections of multiple lighting body components, allowing for multiple lighting arrangements and providing a cost effective and easily configurable lighting design. In some embodiments, multiple lighting components can be attached together by movable joints, allowing further user control over light distribution from the lighting systems.

Abstract: A light fixture includes a LED assembly and a housing. A lens assembly comprises a lens and a first end cap and a second end cap. The end caps are releasably connected to the housing such that the lens and the end caps are releasably mounted to the housing as a unit. The end caps may be releasably mounted to the housing by a deformable, resilient first engagement member that releasably engages a second engagement when the lens assembly is moved relative to the housing in a first direction. A force is created between the first engagement member and the second engagement member sufficient to hold the lens assembly in the housing and low enough that the lens assembly is removable from the housing by pulling the lens assembly in a second direction opposite to the first direction.
