Abstract: A system and/or method can include power of Ethernet (PoE) controller including a PoE interface, a device interface and a controller, communicatively coupled to the PoE interface and the device interface. The controller can be configured to receive device control information via the PoE interface and to generate control instructions in response to the device control information for the device interface.

Abstract: In an embodiment, a luminaire includes a housing with a reflector. A rail is positioned near the reflector and has a light thereon which is configured to emit light into the reflector. The light is reflected from the reflector and passes through a diffuser that can act to ensure the emitted light is desirably defuse. In an embodiment, the diffuser can be removed from the housing for service or replacement.

Abstract: A light emitting diode (LED) fixture is provided. The fixture includes a housing that supports an LED array. A power supply can be coupled to the housing via a connector. A controller with a constant current driver can be configured to actuate the LED array. In an embodiment the controller can be configured to control operation of the LED array based on a sensed signal.

Abstract: A beacon includes an interface, a sensor, an indicator and a controller. The controller is communicatively coupled to the interface, the sensor and the indicator, the controller configured to receive control information via the interface and the sensor and to generate control instructions in response to the control information for the indicator.

Abstract: A LED system is disclosed that includes a fixture with a module mounted in the fixture. The fixture includes a bottom wall with a socket. The module mounts in the socket and is biased into a mated condition with two magnets. The socket includes pads that are engaged by terminals that are supported by the module. A power supply can be mounted on a back side of the fixture.

Abstract: A connector includes a housing that supports a core (which can be magnetic) and provides an inner channel. A power terminal is positioned in the inner channel and provides an electrical path between two opposite sides of the housing. The housing further support a sensor that is positioned in a gap in the core. The housing provides electrical isolation between the core and the power terminal. The connector can therefore provide both a power terminal and the ability to sense current in an integrated design.

Abstract: An LED module can be powered by two conductors and the LED module includes a constant current driver. The constant current driver is configured to provide a predetermined current so long as the input voltage provided on the two conductors exceeds a predetermined level. The constant current driver powers an LED string supported by the LED module and can adjust the current to the LED string based on an input signal. A conversion circuit converts the input voltage to an input signal and provides that input signal to the constant current driver so that dimming can be provided while only using two conductors to provide power.
