Abstract
The present disclosure is directed to a solution providing multi-state power management. In some aspects, the design of the multi-state power management system (MPMS) facilitates switching to battery back up power upon identifying a power outage and further controlling the intensity level of a load (e.g., a light source) such that the light run time meets a minimum required run time. The MPMS may be designed and configured to identify a power outage and a battery status based on the voltage at a voltage input of the lighting device. The design may also include controlling the intensity level of the light source responsive to temperature measurements, e.g., ambient temperature or the temperature of one or more components, to maintain the health of the system.
