A method of controlling a lighting system comprising a plurality of illumination sources each controllable to emit illumination for illuminating the environment and a plurality of control apparatus for use in controlling the illumination emitted from one or more of the plurality of illumination sources, the method comprising: determining the relative position of a first control apparatus compared to a second control apparatus; assigning a function to the first control apparatus, the function defining how the first control apparatus is to control the illumination of one or more illumination sources, wherein the function of the first control apparatus is assigned based on the determined relative position; whereby a first user input can be received at the first control apparatus and the illumination of the one or more illumination sources can be controlled in response to the first user input based on the assigned function of the first control apparatus.

A load control system for controlling an electrical load may include a sensor, a remote control, and a load control device. The remote control may comprise a button and may be configured to wirelessly transmit a digital message in response to an actuation of the button. The load control device may be configured to control the electrical load, be responsive to the sensor, and/or be configured to be associated with the remote control. The load control device may be responsive to the digital message transmitted by the remote control if the remote control is associated with the load control device. The load control device may be configured to automatically operate in a first mode of operation if the remote control is not associated with the load control device, and automatically operate in a second mode of operation if the remote control is associated with the load control device.

The disclosure provides a method and a system for adjusting an irradiation angle of a lamp and a lamp with adjustable irradiation angle. The lamp includes a plurality of infrared receivers and a driving motor. The method comprises: receiving an infrared signal from a remote controller via the plurality of infrared receivers; determining an irradiation angle adjustment value of the lamp based on a plurality of infrared signal intensity values of the plurality of infrared receivers; adjusting an irradiation angle of the lamp via the driving motor based on the irradiation angle adjustment value. In the technical scheme provided by the example of the disclosure, when the irradiation angle of the lamp needs to be adjusted, the irradiation angle of the lamp is controlled only by operating the remote controller.

A system and method for safe decontamination of a vehicle cabin while passengers can be present are disclosed that uses and/or has at least one data storage, at least one processor, at least one infrared (“IR”) sensor, and at least one ultraviolet (“UV”) emitter having a beam steering module. At least one contaminated area in the vehicle cabin is tracked using IR sensor data from the IR sensor. It is determined if there's a direct line of sight between the UV emitter and the at least one contaminated area. If so, UV emitter is activated to target the at least one contaminated area and blocking UV illumination on non-contaminated areas of the vehicle cabin and areas temporarily covered by a passenger.

A luminaire can include a power supply that receives AC mains power from a power source and delivers intermediate power, and can also include a lumen control module coupled to the power supply, where the lumen control module receives the intermediate power from the power source. The lumen control module can include at least one first switch that has multiple positions, and multiple resistors coupled to the at least one first switch, where each position of the at least one first switch corresponds to a resistance of the resistors, where the intermediate power received by the resistors is translated to a current level of a plurality of current levels based on the resistance. The luminaire can also include at least one light source coupled to the lumen control module, where the at least one light source emits a lumen output based on the current level received from the lumen control module.

A gesture-recognition (GR) device made to be held or worn by a user includes an electronic processor configured by program instructions in memory to recognize a gesture. The device or a cooperating system may match a gesture identifier to an action identifier for one or more target devices in a user's environment, enabling control of the target devices by user movement of the GR device in three-dimensional space.

Provided herein are LED warning lights and related methods for detecting oncoming traffic around corners, including in a warehouse. The warning lights have: a LED light module and an external motion sensor operably connected to the LED light module. The device is self-contained with respect to power, communication and alerts in that no other components are required, so that the warning lights are portable and readily positioned as desired and are immediately operable.

Systems, methods and apparatus for providing an availability status associated with a facility. One system includes an illumination indicator, a thermal grid array sensor, and an electronic controller. The thermal grid array sensor is configured to sense an outside region, an entryway region, and an inside region associated with a facility subsystem. The electronic controller is configured to determine the current availability status as unavailable responsive to the thermal grid array sensor detecting a heat signature in the outside region, subsequently in the entryway region, and subsequently in the inside region. The electronic controller is also configured to determine the current availability status as available responsive to the thermal grid array sensor detecting the heat signature in the inside region, subsequently in the entryway region, and subsequently in the outside region. The electronic controller is further configured to control the illumination indicator to indicate the current availability status.
