Abstract: A horticultural luminaire includes a first and second horticultural light sources to provide growth lighting to a plant at a first and second wavelengths. A control unit provides first lighting control signals to the first horticultural light source to modulate the first growth lighting and provides second lighting control signals to the second horticultural light source to modulate the second growth lighting. A LiDAR sensor is connected to the lighting control unit to receive the first and second control signals, and having optics to detect reflected first and second growth lighting to determine the distance from plant to sensor and a biometric property of the plant from the received first and second control signals and detected first and second reflected second growth lighting. In some implementations the LiDAR sensor and first and second horticultural light sources are integrated into the horticultural luminaire.

Abstract: Disclosed herein are embodiments of an occupancy monitoring system. The occupancy monitoring system includes a thermal sensor configured to monitor a gate (e.g., entry way) to a space. The thermal sensor includes a pixel array that generates a pixel value for each pixel in the pixel array, and the pixel value corresponds to a quantity of heat or thermal information detected by a pixel. The occupancy monitoring system acquires pixel values for the pixels of the pixel array. The occupancy monitoring system determines whether there is a change in occupancy of the space based on changes to a first region (or first pixel cluster) of the pixel array and a second region (or second pixel cluster) of the pixel array over time. The occupancy monitoring system may adjust lighting, temperature, and/or security systems for the space as the occupancy changes.

Abstract: Methods and systems are described that enable the simultaneous control of lux, correlated color temperature (CCT), and circadian light (CL) emitted by a lighting system. Aspects also include methods for the adjusting the lux, CCT, and CL with respect to the needs and/or desires of a user, including to provide optimal lighting for light related health. Aspects of the present disclosure also include user interfaces for the simultaneous knowledge and control of lux, CCT, and CL.

Abstract: A method for controlling a chromaticity of total light provided by a lighting system includes detecting the total light by a sensor system, determining a component of the total light that is attributable to uncontrolled light, and selecting a calibration for a sensor based on the uncontrolled light, and using the calibration to adjust the output of the sensor system. The calibration tables may be based on spectral responsivity of the sensors in the sensor system and calibration functions rather than physical light sources. Relative intensities of controllable light sources having different xy values are then adjusted to cause the total light provided by the lighting system to approximate a target chromaticity. A daylighting system implementing this method includes controllable light sources with different xy values. The intensities of the controllable light sources are adjusted to augment sunlight to control the chromaticity of total light provided by the daylighting system.

Abstract: A mount for a fluorescent lamp that comprises a glass base with spaced-apart lead-in wires extending from therefrom. A longitudinal electrode coil containing an emitter material is mounted upon and extends between the lead-in wires. A coating of zinc oxide is provided on the ends of the electrode coil and upon the lead-in wires at least in the area where the electrode coil is mounted.
