A light structure including a first housing having a light engine including at least one lighting scheme comprised of LEDs; and a second housing for containing driver electronics. The driver electronics including at least a mixing integrated circuit (IC) for controlling current to the at least one lighting scheme, and a near field communication (NFC) circuit having a near field communication (NFC) receiver and memory for storing instructions for sending pulse width modulation (PWM) signals from the NFC circuit to the mixing integrated circuit. The NFC receiver can receive an external command signal that the instructions stored in the memory of the NFC circuit employ to provide for an NFC control signal including at least one of the PWM signals to the mixing integrated circuit (IC). The mixing integrated circuit (IC) receiving the control signal sets current to control light characteristics for light being emitted by the light engine.

Driver electronics for light emitting diode light engine with integrated near field communication based controls

A lighting test method that includes connecting a housing including driver electronics and a junction box to a main power source. The main power source is connected to a main power connector in the junction box. The driver electronics includes a first terminal. The method further includes connecting a power testing module to the first terminal to the driver electronics to determine whether the main power source is correctly connected to the main power connector in the junction box. The method further includes replacing the power testing module with a second terminal of a light engine housing. Connecting the first and second terminals provides that the driver electronics are in electrical communication with a light engine within the light engine housing.

Downlight having quick connect driver assembly and test module

A luminaire that includes a housing having a downlight geometry and containing a light engine including light emitting diodes (LEDs), in which the light engine is positioned to emit light through a light emission end of the housing. The housing contains driver electronics for controlling power received by the luminaire for powering the light engine. An access opening on a back surface of the housing exposes the driver electronics. A junction box supporting at least a portion of a wireless control module. The junction box having an electrical pathway opening is engaged to the back surface of the housing. The wireless control module is contained in the knockout of the junction box. Electrical communication between the wireless control module and the driver circuit is across a physical electrically conductive pathway that extends through the electrical pathway opening of the junction box.

Internet of things adaptable downlight

A method of adding a backup power source to a luminaire that includes exposing driver circuitry through a back surface of a housing for a luminaire having a downlight geometry. The housing contains a light engine that is positioned to emit light through a light emission end of the housing. The driver electronics controls power received by the luminaire for powering the light engine. The method may continue with connecting a battery junction box having an electrical pathway opening in reversible engagement to the back surface of the housing by snap fit engagement. The method may further include connecting a backup battery unit to the luminaire by wiring extending from the battery backup unit through the electrical pathway opening in the junction box to the driver electronics for the luminaire.

Emergency backup ready downlight

A lamp is provided that includes a first housing having a recessed down lamp geometry for containing a light emitting diode (LED) light source, and a second housing for containing driver electronics including an exterior switch for selecting lighting characteristics of light being projected by the light emitting diode (LED) light source, wherein the first housing containing the light emitting diode (LED) light source and the second housing including the driver electronics are electrically connected through a reversible connector.

Downlight having quick connect driver assembly with switch selectable light characteristics

A light structure that includes a driver electronics housing including two laterally disposed compartments for electrical connections on opposing sides of a centrally positioned compartment including driver electronics, wherein a first compartment of the two laterally disposed compartments includes a main power connector for connection to a main power source. The light structure further includes a light engine housing having a recessed down light structure geometry for containing a light emitting diode (LED) light source. The light structure further includes a reversible driver to light source connector for electrically connecting the light engine housing containing the light emitting diode (LED) light source and the driver electronics housing including the driver electronics.
