    摘要: Systems and methods disclosed herein includes a measurement device to enable dimensional metrology and/or 3D reconstruction of an object. The measurement device is positioned between the object and reference luminaires (e.g., light emitting diodes or other light sources). The measurement device uses the reference luminaires to determine the position and orientation of the measurement device. The measurement device may include a camera oriented towards the reference luminaires and may acquire/use images of reference luminaires to determine the position and orientation of the measurement device. Using the reference luminaires, the system may determine positions and orientations of the measurement device when the images of the reference luminaires are taken. The system may be configured to use the positions and the orientations of the measurement device to determine dimensions and/or 3D models of the object.

    摘要: 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.

    摘要: Described herein are ambient lighting devices, methods, and systems that utilize at least one multimode artificial ambient light source, a control unit, and a remote image sensor. The control unit couples to at least one artificial ambient light source and is configured to output at least one control signal to the at least one artificial ambient light source. The at least one multimode artificial ambient light source is configured to output light of varying color and color temperature in response to said at least one control signal. The remote image sensor couples to the at least one control unit and is configured to detect at least one color and intensity characteristic and output an output signal to the at least one control unit, based on said color and intensity characteristic detected.

    摘要: There is provided herein a method for starting a high intensity discharge lamp and a ballast incorporating the same. In a preferred embodiment, the method comprises the steps of: (a) obtaining a cumulative probability function of breakdown times, P(t), for the lamp at a voltage, V; (b) determining a minimum pulse length, Tp, for a selected probability of ignition, Pign; (c) if the lamp is operable at the minimum pulse length, then operating the lamp with a DC pulse having a duration Tp and voltage V; (d) or alternatively, if the lamp is not operable at the minimum pulse length, then determining a relaxation time, Trel, for a burst mode, selecting a probability of ignition per burst, Pb, calculating a minimum number of pulses, np, in a burst, determining a number of bursts, Nb, for the selected probability of ignition, and operating the lamp in the burst mode with Nb bursts separated by relaxation time, Trel, with each burst having np pulses of voltage V.
