A vehicle headlamp system includes a vehicle supported power and control system including a data bus. A sensor module can be connected to the data bus to provide information related to environmental conditions or information relating to presence and position of other vehicles and pedestrians. A separate headlamp controller can be connected to the vehicle supported power and control system and the sensor module through the bus. The headlamp controller can include an image frame buffer that can refresh held images at greater than 30 Hz speed. An active LED pixel array can be connected to the headlamp controller to project light according to a pattern and intensity defined by the image held in the image frame buffer and a standby image buffer can be connected to the image frame buffer to hold a default image.

An emergency lighting system that includes a storage device, an emergency lighting device, an area control device and an external device. The emergency lighting device includes a light, a first controller having a first electronic processor configured to perform a self-diagnostic test, and a first input/output (I/O) device configured to transmit data associated with the self-diagnostic test. The area control device includes a second I/O device configured to receive data associated with the first self-diagnostic test form the first I/O device and transmit the data associated with the self-diagnostic test to the storage device.

A decorative lighting system including a sensor device; a wiring harness comprising an insulated conductor and a plurality of lighting elements; a controller in communication with the wiring harness and the sensor device, the controller comprising a processor, a memory, and a wireless communication module; and wherein the controller is configured to control the plurality of lighting elements based at least in part on information received from the sensor device.

The invention relates to an airfield light comprising a body, a medium intensity lighting arrangement, and a high intensity lighting arrangement. The medium intensity lighting arrangement provides an omnidirectional light source, and the high intensity lighting arrangement provides a unidirectional or bidirectional light source. The invention is energy efficient compared to conventional airfield lights, and has particular application to temporary airfields. LEDs may be used as the light sources.

An illumination device for illuminating a region monitored by at least one image sensor. The illumination device has at least one light source carrier with at least one light source arranged thereon. Furthermore, the illumination device has a control and interface unit and an adjusting unit, which can be actuated by the control and interface unit and with which the light source carrier is positionally adjustable.

A NEMA edge gateway is provided, which can be connected to a mobile communication network and can be used with a NEMA Luminaire of an existing streetlight to receive electrical energy from circuitry of the streetlight. The NEMA edge gateway can provide networking and power for a serial device and an IP device respectively, making both of them operate smoothly and able to be networked, and thereby expanding IoT applications. This is also to resolve difficulty in finding locations for placing gateways in order to greatly increase the number of gateways built in urban areas and fulfill increasing local communication service requirements.

A system (1) is configured to receive device control information. The device control information specifies how devices, e.g. lights, should be controlled. The device control information may identify specific devices or specify device requirements, for example. The system is further configured to form a group of identified devices by analyzing the device control information, the identified devices of the group being controlled similarly according to the device control information. The system is also configured to transmit at least one message comprising an identifier of the group to allow the identified devices to be configured to carry out one or more commands comprising the identifier when receiving such one or more commands. The at least one message identifies the identified devices of the group.
