Abstract: This disclosure relates to lighting fixtures, such as suspended lighting fixtures. Devices according to the present disclosure provide lighting fixtures capable of emitting in one or more primary directions, while simultaneously emitting in a direction toward a mount surface, reducing undesirable areas of insufficient light and more efficiently illuminating a space. Lighting fixtures disclosed herein can achieve this increase in illumination efficiency in many ways, including utilizing various lighting element arrangements, such as dual-sided lighting elements, and various lens arrangements, such as lens shape affecting the direction of emitted light.

Abstract: Retrofit systems and methods are disclosed for lighting installations, and in particular, to retrofit systems and methods used to retrofit troffer-style lighting installations with LED light sources. Retrofit systems can be used with different light fixtures, but those described are particularly adapted for use with troffer-style fixtures. These retrofit systems can provide the same amount of light as traditional light fixtures already do, for example 1600-4000 lumens or more. The retrofit systems can be used with many different light sources but are particularly well-suited for use with solid state light sources or light engines, such as those utilizing LEDs. Some embodiments of the present invention comprise a mechanical mounting system for installing an LED light engine within an existing lighting system housing or pan, such as a troffer pan, without penetrating the ceiling plenum.
