Abstract: A lighting fixture forms at least a portion of a grid system for a suspended ceiling. The lighting fixture includes a runner having a substantially uniform, elongate, thin web coupled to a fixture base defining first and second flanges disposed on opposite sides of the web. The flanges support respective ceiling tiles. The base defines a fixture receptacle configured to receive a light source. A retainer may be supported by the fixture base to secure the light source in the fixture receptacle.

Abstract: Lighting fixtures for attachment to architectural surface structures are adapted to hold light sources. The lighting fixtures may include a base plate and mounting brackets. Clamps are provided that may bias the light source in either the forward or rearward direction. The clamps may include spring arms that center the light source within the fixture in addition to retaining the light source in place. The fixtures may further accommodate overlying structures, such as lenses. The lighting fixtures facilitate use with a variety of different architectural structures and formation in various shapes.
