The present disclosure generally pertains to systems and methods for verifying operation and configuration of a lighting network. In some embodiments, a site controller is configured to receive sensor data from a plurality of sensors and to transmit commands to nodes of a lighting network for controlling light sources based on the sensor data. The site controller is also configured to store a site plan including a listing of the nodes and, for each of the nodes, indicating a number of sensors to be coupled to the respective node. The site controller is further configured to detect the sensors coupled to the nodes based on the sensor data and to compare the detected sensors to the site plan for determining whether the detect sensors is consistent with the site plan. If not, the site controller is configured to provide an alert.

An organic light-emitting diode comprising an organic layer sequence, a radiation exit area and an encapsulation. The organic layer sequence comprises at least one radiation-emitting region which generates electromagnetic radiation in the spectral range from infrared radiation to UV radiation during operation. The radiation exit area is structured, so that the electromagnetic radiation has a directional emission profile. The encapsulation forms a seal of the organic layer sequence against environmental influences.

A microcontroller based multifunctional electronic switch using a detection circuit design to convert external control signal into message carrying sensing signal readable to the microcontroller. Based on a time length of sensing signal and a format of the sensing signal received in a preset instant period of time the microcontroller through the operation of its software program codes is able to recognize working modes chosen by the external control signal generated by user, and thereby selecting appropriate loops of subroutine for execution. The system and method of the present invention may simultaneously be applicable to detection circuit design using infrared ray sensor, electrostatic induction sensor, conduction based touch sensor or push button sensor for performing multifunctions such as controlling on/off switch performance, diming or speed control and delay timer management within the capacity of a single lighting load or an electrical appliance.

Various systems and method related to home automation systems are presented. A service robot system may be present that includes a service robot that autonomously moves within a structure to perform a household task. The service robot system may include a wireless communication interface, wherein the service robot system is configured to transmit, via the wireless communication interface, an indication of robot activity indicative of the service robot moving within the structure. Such a home automation system may also include a home security system that includes one or more motion sensors that detect motion within a structure. The home security system may be configured to distinguish intrusion activity (e.g., a burglar) from robot activity based at least in part on the indication of robot activity.

An RF controlled lighting unit is provided, suitable for connection to at least one of a dimmer for adjusting a phase cut angle of input mains voltage in accordance with an adjustable dimming level or an electronic switch for selecting between on- and off-states. The lighting unit includes a solid state light source; a radio circuit for receiving a wireless control signal; a rectifier circuit for rectifying the input mains voltage received from the electronic switch or the dimmer; a first power converter for driving the solid state light source in response to the rectified input mains voltage and delivering power to the radio circuit; and a second power convertor for delivering power to the radio circuit when the rectified input mains voltage becomes inadequate for the first power converter due to the phase-cut angle of the rectified input mains voltage or the off-state of the electronic switch.

A lamp control device may include: a lamp including an LED module having a plurality of LED channels; a converter configured to receive a voltage corresponding to a turn signal, convert the voltage into an output voltage and internal voltage, and supply the output voltage to the LED module; and a controller configured to start counting a preset delay time when the internal voltage is supplied from the converter, and control the plurality of LED channels to sequentially light up at intervals of the delay time.

In order to make flexible, reliable lighting possible for industrial image processing, it is provided that a lighting unit (2), having a lighting device (5) comprising a number of light sources (6), receives a set value of the lighting via a data bus from a lighting control unit (10), that the lighting unit (2) captures a state variable (Z) of the lighting unit (2) and/or the surroundings of the lighting unit (2), and that the lighting unit (2) adjusts the set value in a closed control loop separately and independently from the lighting control unit (10) in that a control variable for at least one light source (6) is calculated in the lighting unit (2) and adjusted at the at least one light source (6).

The present disclosure relates to a lighting fixture that includes a driver module and at least one other module that provides a lighting fixture function, such as a sensor function, lighting network communication function, gateway function, and the like. The driver module communicates with the other modules in a master/slave scheme over a communication bus. The driver module is configured as a slave communication device, and the other modules are configured as master communication devices. As such, the other modules may initiate communications with the driver to send information to or retrieve information from the driver module.

An occupancy sensor with integral light level sensors is configured to turn off or disable peripheral circuits and go into a periodic deep sleep mode to reduce phantom loading. Peripheral circuits include occupancy sensor circuits and relay drive circuits, but may include other circuits such as communication circuits. The sensor may be configured to periodically wake itself up, check ambient light conditions to see if lighting is below the set threshold. If it is not, the sensor goes back to sleep. If it is, then the sensor can power up the occupancy sensor circuit to see if the space is occupied; if not, it can go back to sleep. If the space is occupied, it can turn on other peripheral circuits necessary to control the load.

An example of a building automation system utilizes intelligent system elements, some of which are lighting devices having light sources, and some of which are utility building control and automation elements. Some utility building control and automation elements include a controllable mechanism for use in control of some aspect of the building other than lighting. Another intelligent system element may include either a user interface component and be configured as a building controller, or include a detector and be configured as a sensor. Each intelligent system element includes a network communication interface, processor, memory and programming to configure the intelligent system element as a lighting device, utility building control and automation element, controller or sensor. At least one of the intelligent lighting devices is configured as a building control and automation system server. Several examples, however, implement the overall control using distributed processing.
