A system to control solid state light sources, including a photosensor responsive primarily to wavelengths of light outside the emitted light band of wavelengths that the solid state light sources emit when the solid state light sources are in the ON state, and which produces a light level signal representative of a level of sensed light primarily for wavelengths outside of the emitted light band of wavelengths. A set of circuitry receives the light level signal representative of the sensed level of light from the photosensor, determines a contribution by the solid state light sources to the sensed level of light, and uses a compensated light level or a compensated threshold in assessing a dusk condition or a dawn condition when the solid state light sources are in the ON state to compensate for the contribution by the solid state light sources to the sensed level of light.

Photocontroller and/or lamp with photocontrols to control operation of lamp

Systems and methods which leverage the wireless communication capability present in wireless-enabled luminaires where the lamps include a short-range wireless transceiver and can be controlled by a smart appliance. The wireless capability of a luminaire may be paired with a compatible wireless interface system (e.g., adapter system) that allows for control of the luminaire via plug-in or hard-wired photocontrols and wireless network lamp control nodes. An adapter system may be provided that replaces a standard wired receptacle of a luminaire. The adapter system may include a wired interface to the luminaire which provides power to the wireless adapter system. The wireless adapter system may include a receptacle interface that receives a plug of a control node, such as photocontrol or a networked control node. The wireless adapter system may also include a wireless interface circuit that communicates control, status or other data between the connected control device and the luminaire.

Systems and methods for outdoor luminaire wireless control

A protection system and operating method thereof promotes the longevity of components of a control subsystem. The protection apparatus may include a first connector for connecting to the control system and a second connector for connecting to a target system. The protection apparatus detects states of a component of the control subsystem over time and causes a state transition of a switching circuit of the protection apparatus based on the detected states of the control subsystem. The state transition of the switching circuit of the protection system may be initiated after a defined period of time has elapsed after detecting states of the control subsystem component. The state transition of the switching circuit may be a transition between an open state in which power is not provided to a node of the second connector and a closed state in which power is provided to the node of the second connector.

Switch protection apparatus and operating method thereof

An illumination system verifies whether one or more aspects of an output signal provided by a photosensitive transducer fall within a threshold of an expected value for the aspect. The aspect may include a sunrise time, a sunset time, a dawn time, a dusk time, a solar noon time, a solar midnight time, or similar. Upon verification the illumination system uses a microcontroller to adjust one or more output parameters of a solid-state light source responsive to the output signal provided by the photosensitive transducer. Where verification is not possible, the illumination system uses the microcontroller to adjust one or more output parameters of the solid-state light source responsive to a schedule.

Apparatus and method of operating a luminaire

An illumination system verifies controls the operation of a luminaire without the use of any photometric data. The illumination system uses data indicative of a current time, date or latitude to determine one or more aspects of a solar event. Such aspects can include a scheduled, predicted or expected time of occurrence of the scheduled solar event. Responsive to the determination of a scheduled, predicted or expected time of occurrence of the scheduled solar event, a control subsystem can adjust the luminous output of a light source.

Apparatus and method for schedule based operation of a luminaire

Using Bluetooth to provide the network management functions such as device discovery, service discovery, security negotiation, and connection establishment. Upon a Bluetooth connection being established between the Bluetooth-enabled devices an IP channel availability query is made. This is accomplished by using information request signals from the Bluetooth L2CAP protocol layer. If an IP channel is available on both the devices and the communication modules using that IP channel are compatible the devices will then establish a secondary Internet Protocol (IP) based data channel between them.
