An emergency lighting module for providing emergency power to a solid state luminaire. The emergency lighting module includes a first input configured to receive a DC input voltage from the solid state luminaire, a second input configured to receive a status signal indicative of the status of an AC line voltage, and a first output configured to supply a DC output voltage to the solid state luminaire. The emergency lighting module is configured to supply the DC output voltage to the solid state luminaire in response to a reduction of the AC line voltage.

The present disclosure is directed to a method, non-transitory computer readable medium and apparatus for remotely receiving information from and configuring a battery-backed emergency lighting system. In one embodiment, the method includes establishing a wireless communication session with a web server via a wireless fidelity (WiFi) connection, receiving a request for information related to the battery-backed emergency lighting system and a request to change a configuration of the battery-backed emergency lighting system over the wireless communication session, configuring the battery-backed emergency lighting system in accordance with the request to change the configuration and sending the information that is requested.

The invention provides a plurality of individually addressable radio frequency (RF) modules, any of which can be installed with any electrical device such as an ambient condition sensor or an ambient condition modifier. A prime example would be a light fixture, whether with or without a dimmable light source efficient dimming and integrated smart sensor networking related to the lighting system itself or to other systems such as parking monitors, fire alarm monitors or security alarm monitors. Independent control processing in each lighting fixture or electrical device allows a multiplicity of sensors to be locally employed and their data to control local conditions or communicate to adjoining fixtures and electrical devices and thereby control larger portions of the lighting system network or network to several unrelated systems.

A light fixture can include at least one light source, and at least one power supply that receives primary power, where the at least one power source generates final power using the primary power, where the at least one power supply delivers the final power to the at least one light source. The light fixture can also include a controller coupled to the at least one power supply, where the controller detects an adverse event, and where the controller controls the at least one power supply to provide the final power to the at least one light source during the adverse event.

A linear light-emitting diode (LED) lamp comprising an emergency circuit is used to replace a luminaire operated in a normal circuit with alternate-current (AC) mains. The normal circuit comprises a step-down regulator circuit and a load control relay whereas the emergency circuit comprises a rechargeable battery, a step-up regulator circuit, and a self-diagnostic circuit. The linear LED lamp can be auto-switched from a normal mode to an emergency mode according to availability of the AC mains and whether a rechargeable battery test is initiated. The load control relay is configured to convey a forward electric current and a reverse electric current to and from the LED arrays. The self-diagnostic circuit is configured to provide a test sequence and to auto-evaluate battery performance. The step-up regulator circuit adopts an unconventional low power scheme to prolong an emergency lighting time using a limited power of the rechargeable battery.

The controller (16) may be coupled to the digital communication interface (12) and the DC power supply (14) and may be configured to control the emergency driver (10) to operate in a first operation mode. The input signal (41) received at the digital communication interface (12) may be a digital input signal when the emergency driver is operating in a first operation mode.

Various embodiments of the present technology may comprise a system disposed within a structure comprising a network of individually addressed devices for providing building safety, security, and operational efficiency. Each device in the network may comprise a microcontroller electrically connected to a communication module, at least one output module, and/or at least one sensor module.
