Abstract: An electrical device can include a sensor module that measures at least one parameter, where the at least one parameter is associated with determining the presence of a living being in a volume of space. The electrical device can also include a controller coupled to the sensor module, where the controller receives a measurement of the at least one parameter to determine whether the living being is in the volume of space. The electrical device can further include at least one ultraviolet (UV) light source coupled to the controller, which operates the at least one UV light source to emit UV light when the living being is not in the volume of space, and where the controller prevents the at least one UV light source from emitting the UV light when the living being is in the volume of space.

Abstract: A lighting fixture includes a light source that emits an illumination light and a receiver configured to receive a lighting control message from a photo sensor device. The lighting fixture further includes a lighting controller configured to adjust the illumination light based on the lighting control message. Adjusting the illumination light by the lighting controller includes changing a Correlated Color Temperature (CCT) of the illumination light.

Abstract: A luminaire can include a power supply that receives AC mains power from a power source and delivers intermediate power. The luminaire can also include a control module coupled to the power supply, wherein the control module receives the intermediate power from the power source, where the control module includes at least one first switch that has multiple positions, where each position of the at least one first switch corresponds to an output power level of a plurality of output power levels. The output power level can correspond to a discrete photometric distribution by a plurality of light sources of the luminaire.

Abstract: A lighting device includes a first string of light emitting diodes (LEDs) configured to emit a warm white light having a warm Correlated Color Temperature (CCT). The lighting device further includes a second string of LEDs configured to emit a cool white light having a cool CCT. The lighting device also includes green light LEDs that emit a green light. A flux of the green light is controlled based on a flux of the cool white light or a flux of the warm white light. The flux of the warm white light and the flux of the cool white light change proportionally with respect to each other.

Abstract: A surge monitoring circuit for detecting transient spikes in an input voltage includes a voltage divider circuit that generates a divider output voltage from the input voltage, a reference voltage generator circuit that generates reference voltages, and a comparator circuit that generates comparator signals by comparing the divider output voltage to the reference voltages. The surge monitoring circuit further includes a processor configured to predict, at least based on the comparator signals, an expected failure of a surge suppressor circuit that suppresses the transient spikes, where the comparator signals indicate detections of divider output transient spikes in the divider output voltage. The divider output transient spikes correspond to transient spikes in the input voltage, where the divider output transient spikes have a higher voltage than the one or more reference voltages.
