A light-emitting diode (LED) luminaire comprises an emergency-operated portion comprising a rechargeable battery with a terminal voltage, a self-diagnostic circuit, and a node modulator-demodulator (MODEM). The LED luminaire can auto-switch from a normal power to an emergency power according to availability of the normal power and whether a rechargeable battery test is initiated. The self-diagnostic circuit comprises a clock and is configured to initiate self-diagnostic tests and to auto-evaluate battery performance according to test schedules with the terminal voltage examined and test results stored. The LED luminaire further comprises a remote controller configured to initiate control signals with phase-shift keying (PSK) signals transmitted and to collect test data to and from the node MODEM. The node MODEM is configured to demodulate the PSK signals and to send commands to the self-diagnostic circuit to request responses accordingly.

The lamp also includes a battery pack in electrical communication with the battery charge controller, an AC mains driver electrically connected to the first pair of primary electrical contacts, an emergency driver electrically connected to the battery pack, and an LED array in electrical communication with the AC mains driver and the emergency driver.

A device for a battery backup system comprising: a Lighting fixture; an LED light source, the LED light source accepting the battery backup system. The battery backup system comprising batteries, an indicator light and a test button, battery compartment access covers, and battery compartments. The batteries feed an inverter to run the LED light source. The battery system is plugged into the light source.

A luminaire includes a luminaire housing having a lower wall, an upper wall, and a plurality of side walls defining a first interior. A first control component is positioned in the interior. A light emitter is connected to the housing and operatively connected to the control component. A control module is connected to an exterior of the luminaire housing. The control module includes a base and a cover defining a second interior, and a second control component positioned in the second interior.

A light engine for a lighting fixture includes a bracket, with multiple mounting surfaces configured at different angles to form a substantially concave region, and a plurality of light emitting diode (LED) modules mounted to the multiple mounting surfaces to project an axis of a light beam from each of the plurality of LED modules along substantially a same illuminating plane. The light engine includes a first set of lenses with a first type of optical surface for focusing a first portion of the plurality of LED modules and a second set of lenses with a second type of optical surface, different than the first type, for focusing a second portion of the plurality of LED modules.

A luminaire includes a rear housing section having an opening in communication with an exterior environment. A cover is connected to the rear housing section. An insert extends between the rear housing section and the cover. The insert includes a base and a fin member extending from the base. An air passageway is formed between the insert and the cover and is in fluid communication with the opening. A control component is connected to the base. A light emitter assembly is connected to the insert and controlled by the control component. The insert provides thermal communication between the control component and the light emitter and the fluid passageway.

A processing unit in a dual-mode lighting fixture receives, via a light pipe of the lighting fixture, a test command signal from a remote control and initiates, based on the test command signal, testing for emergency condition lighting of the lighting fixture. The processing unit receives, via the light pipe, a control command signal from the remote control and controls, based on the control command signal, normal condition lighting of the lighting fixture. The processing unit also monitors feedback loops from a battery, a charger, or a set of LED lamps in the lighting fixture and presents, via the light pipe, a status color indication based on the monitored feedback.

A Light device having built-in digital data means is powered by an unlimited power source for a lamp-holder, LED bulb, or light device connected to unlimited power source by prongs or a base that or conductive wires can be inserted into a socket that would otherwise receiving a bulb. The device may take the form of a webcam having auto tracking added one of plurality functions to make different products and functions and retractable prongs that plug directly into a wall outlet or insert into existing lamp base or incorporate conductive wire to make electric connection at least one of built-in camera, storage unit, wireless kits, Bluetooth kits, motion sensor, light device.
