    摘要: Methods and systems are provided for slewing a light beam axis directly between points on the ground. One method involves determining a first position associated with a beam axis of a lighting arrangement in a Cartesian reference frame based on an initial orientation of the lighting arrangement in a spherical reference frame, determining an adjustment for the lighting arrangement in the Cartesian reference frame in response to a user input, determining an updated position for the beam axis in the Cartesian reference frame based on the first position and the adjustment in the Cartesian reference frame, transforming the updated position for the beam axis in the Cartesian reference frame to an updated orientation of the lighting arrangement in the spherical reference frame, and concurrently commanding actuators associated with the lighting arrangement to slew the lighting arrangement from the initial orientation to the updated orientation in the spherical reference frame.

    摘要: An adjustable-height pendant luminaire is proposed which comprises the following: a luminaire head, a ceiling mounting unit from which the luminaire head is suspended by means of cables, a height adjustment unit arranged in the ceiling mounting unit, a sensor arrangement having at least one sensor arranged on the luminaire head, wherein the at least one sensor is configured as a near-field sensor designed to detect a hand of a user in the proximity of the sensor for the detecting of gestures as non-contact control commands, and a control unit in communicative connection with the sensor arrangement and the height adjustment unit. The control unit is configured to send a control command to the height adjustment unit for changing the vertical position of the luminaire head upward or downward.

    摘要: A method (500) for monitoring rotation of a lighting unit (200) includes the steps of: providing (510) a lighting unit comprising a sensor (32), a controller (22), a first gear (212) configured to rotate the lighting unit about a first axis, and a second gear (214) configured to rotate about a second axis, wherein the second axis is substantially perpendicular to the first axis; rotating (520) one of the first and second gears, wherein the rotation causes rotation of the lighting unit about the first axis from a first position to a second position; generating (530), by the sensor in response to rotation of the second gear, sensor data; and translating (540), by the controller, the sensor data into information about rotation of the first gear.
