Definitions

  • the present invention relates to a height-adjustable pendant lamp according to the subject matter of claim 1.
  • Height-adjustable pendant lights with a light head that is suspended from a ceiling mounting unit by means of cables are known from the prior art.
  • DE 20 2007 017 625 U1 describes a height-adjustable pendant lamp in which the cables for suspending the lamp head are rolled up on mechanically pretensioned winding drums that are attached to the ceiling. So that the suspended lamp head remains in its current vertical position, the winding drums have a winding brake that prevents unintentional unwinding of the cables rolled up on the winding drums.
  • the user grabs the lamp head and moves it manually up or down.
  • the cables from which the lamp head is suspended are rolled up onto or from the winding drum, so that the length of the cable sections between the winding drums and the lamp head and thus the vertical position of the lamp head can be changed.
  • a disadvantage of the known height-adjustable pendant lamp is that the adjustment of the vertical position or the height of the lamp head requires manual movement of the lamp head. If excessive pulling force is used, there is a risk that the pendulum will become detached from the ceiling and damaged. In addition, the lamp head can become dirty when the user is adjusting the height.

  • the control unit is configured to send a control command to change the position of the lamp head in the vertical direction upwards or downwards to the height adjustment unit when a first gesture is detected on the sensor arrangement, and a control command to change the height adjustment unit when a second gesture is detected on the sensor arrangement
  • the height adjustment unit is configured to change the position of the lamp head in the vertical direction in accordance with the control commands received from the control unit.
  • An essential point of the invention consists in the idea of not providing a mechanically actuable mechanism for the height adjustment of the lamp head, but rather realizing the height adjustment by means of a controllable height adjustment unit.
  • Corresponding control commands for moving the lamp head up or down are generated by means of the contactless detection of gestures that a user makes in the immediate vicinity of the sensor arrangement attached to the lamp head.
  • the pendant lamp according to the invention provides an extremely convenient solution for adjusting the height of the lamp head. On the one hand, it is not necessary to touch the pendant lamp, so that there is no risk of damage to or contamination of the pendant lamp.

  • an infrared sensor can be used as the near field sensor, which detects infrared radiation emitted by the hand of the user when reaching into the detection area.
  • the sensor arrangement can have radiation sources, for example infrared light sources, as well as corresponding sensors that detect radiation that is emitted by the radiation sources and reflected by an object in the detection area. Any type of sensor that reacts without contact to approach, i.e. without direct contact, can also be used as a near-field sensor.

  • the detection of the first or second gesture causes the transmission of a control command to the first illuminant 12a or to the second illuminant 12b for dimming the first illuminant 12a or the second illuminant 12b.
  • the brightness of the first illuminant 12a or the second illuminant 12b is changed continuously as long as the hand 30 of the user is in the detection range of the first sensor 11a or the second sensor 11b.
  • control unit 23 is set in the second mode by default.
  • the detection of the third gesture causes the control unit 23 to switch to the first mode for a predetermined period of time of, for example, ten or five seconds. If the first or second gesture is detected during this time, the lamp head 10 is moved up or down. If no gesture is detected after the predetermined period of time has elapsed, the control unit 23 automatically switches back to the second mode.
  • the sensor arrangement 11 and the control unit 23 can be used to detect further gestures. For example, a brief intervention in the detection area of the first sensor 11a or the second sensor 11b, which lasts less than the predetermined minimum time, can be detected as a fourth or fifth gesture.
  • a brief intervention in the detection area of the first sensor 11a or the second sensor 11b which lasts less than the predetermined minimum time, can be detected as a fourth or fifth gesture.
  • the lamp head 10 In the first mode, when the fourth or fifth gesture is detected, the lamp head 10 can be moved into a respective preset vertical position.
  • the first light source 12a or the second light source 12b can be switched on and off.
  • the fourth and fifth gestures can also be used in the first mode to start and stop the movement of the lamp head 10 in the vertical direction.
  • the control device 23 is configured to send a control command for the continuous movement of the lamp head 10 in the vertical direction downwards or upwards to the height adjustment unit 21 if the lamp head 10 was not in motion before the gesture was detected .
  • the control device 23 is also configured to issue a control command when a certain gesture is detected or when any gesture is detected To send completion of the movement of the lamp head 10 in the vertical direction to the height adjustment unit 21 if the lamp head 10 was in motion before the gesture was detected.
  • the height adjustment of the lamp head 10 by means of the fourth and fifth gestures accordingly works as follows: If the lamp head 10 is in a motionless state (and if the first mode is activated according to the exemplary embodiment described with reference to FIG. 6), the user moves his Hand 30 is shorter than a predetermined minimum time in the detection area of the sensor 11a (fourth gesture) or 11b (fifth gesture).
  • control unit 23 is configured to send a control command to the when the fourth or fifth gesture is detected
  • This control command is purely a start command for the movement of the lamp head 10 - the movement in the vertical direction does not end with the user removing his hand 30 from the detection range of the sensor arrangement 11.
  • the movement of the lamp head 10 is only ended when a further gesture is detected on one of the sensors of the sensor arrangement 11.
  • a particularly convenient method for height adjustment can be implemented, since the user does not have to keep hand 30 continuously in the detection area of sensor arrangement 11 during the height adjustment process.
  • the control unit 23 is configured to send a control command to terminate the movement of the lamp head 10 when any gesture is detected, the operational safety of the pendant lamp is also increased, since the termination of the movement in this case can also be triggered by an obstacle that occurs when the vertical movement occurs in the detection area of the sensor arrangement 11 and with which the lamp head 10 would collide without terminating the movement.
