Abstract
Embodiments of this invention provide a secondary, or back-up, lighting system for light fixtures having a primary light source. The back-up lighting system is configured to mount onto a support structure of the light fixture. The back-up lighting system includes a light source and a lens with optical properties. A housing retains the light source and lens. The back-up lighting system may include a controller that monitors the main power source for the primary light source of the light fixture. The controller activates the light source of the back-up lighting system upon detecting power restoration after a power loss. In some embodiments of this invention, the back-up lighting system includes a secondary power source that powers the back-up lighting system during a loss of power.
