Furthermore, it is conceivable that the duration of the delayed lighting can be set in minutes by means of the manipulation sequence of the operating element 50.

[0033] Furthermore, the construction site lighting device 10 includes an optical, acoustic, and / or tactile output unit 54, wherein the control or adjustment unit 28 is configured to output status information of the delayed lighting function based on the activation of the delayed lighting function via the output unit 54. This status information is specifically configured to differ from the purely delayed lighting of the lighting unit 16. The status information is information regarding the on or off state of the delayed lighting function, the maximum or minimum operating time of the delayed lighting duration, the remaining delayed lighting duration, or the like. The output unit 54 is configured to notify the user of the status information of the construction site lighting device 10 via optical, acoustic, and / or tactile output. The status information is displayed via the lighting unit 16 of the construction site lighting device 10, for example, by means of flashing, flashing sequences, color changes, or the like of the lighting unit 16. Alternatively, output unit 54 may include at least one additional, optical, acoustic, and / or tactile output element, particularly configured differently from illumination unit 16, such as a status LED, speaker, buzzer, vibration actuator, piezoelectric element, or the like, by means of which status information of the delayed illumination function can be output, for example by means of different colors, flashing, tones, vibration frequencies, amplitudes, or the like. Furthermore, output unit 54 may include an output element configured as a display, on which at least one status message, the selected / set maximum operating time, and / or the remaining delayed illumination duration can be displayed. It is also possible that the output element is configured as a piezoelectric buzzer, speaker, voice module, or the like. Status information can be output via voice notification. Alternatively, status information can be output via tone or tone sequence. Additionally, the output element may also be configured as a vibration actuator, piezoelectric actuator, force feedback element, or the like, configured to output tactile signals perceptible to the user. This type of actuator or force feedback element is preferably arranged on the operating element 50, in the housing 12, or on the housing.

[0034] Furthermore, the construction site lighting device 10 has a communication interface 56, which is configured to receive signals, particularly electrical or electronic signals, from an external controller 66, especially from a mobile terminal device, for activating and / or parameterizing a delayed lighting function. The control or adjustment unit 28 is configured to take the received signals into account when controlling or adjusting the delayed lighting function. The communication interface 56 is configured as a wireless communication interface 56 for transmitting and / or receiving radio signals, radio waves, infrared signals, and / or Bluetooth signals. It is also conceivable that the communication interface 56 is configured to exchange data with at least one other construction site lighting device 10, particularly one of the same type.

[0035] Figure 3A schematic flow chart of a method 100 for operating a construction site lighting device 10 is shown. In at least one method step 110, the delayed lighting function of the construction site lighting device 10 is controlled or adjusted by means of a control or adjustment unit 28 of the construction site lighting device 10, based on the manipulation of an operating element 50 of the construction site lighting device 10, which causes the lighting unit 16 to be turned off. In method step 110, the on / off state of the lighting unit 16 is determined when the operating element 50 is manipulated. When the lighting unit 16 is on, the delayed lighting function is activated with a delayed lighting duration, in particular with a preset value such as 10 seconds or the like.

[0036] After the delayed lighting duration ends, the lighting unit 16 is automatically turned off by means of the control or adjustment unit 28, especially without further user interaction. In at least one method step 120 of method 100, the delayed lighting duration, especially the value of the delayed lighting duration, is set by the duration of manipulation of the operating element 50, multiple manipulations, and / or manipulation sequences. The delayed lighting duration, especially the value of the delayed lighting duration, is set according to the duration of manipulation of the operating element 50, wherein one second of manipulation duration corresponds to one minute or the like of delayed lighting duration. It is also conceivable that three levels of different values ​​for the delayed lighting duration are stored in the storage unit of the control or adjustment unit 34, which are progressively recalled according to the duration of manipulation of the operating element 50. Alternatively, it is conceivable that the level of the delayed lighting duration is selected by means of the manipulation sequence and / or the number of manipulations of the operating element 50. Furthermore, it is conceivable that the value for the delayed lighting duration in minutes is set by means of the manipulation sequence of the operating element 50.

[0037] In at least one method step 130 of method 100, the status information of the delayed lighting function is output by means of the optical, acoustic, and / or tactile output unit 54 of the construction site lighting device 10, based on the activation of the delayed lighting function. This status information is specifically configured to differ from the purely delayed lighting of the lighting unit 16. It is also conceivable that the lighting unit 16 is part of the output unit 54, and the status is displayed by means of the lighting unit 16 of the construction site lighting device 10, for example by means of the flashing, flashing sequence, color change, or the like of the lighting unit 16. Furthermore, it is possible that the output unit 54 informs the user of information about the status of the construction site lighting device 10 by means of acoustic and / or tactile output. Alternatively, the status information of the delayed lighting function is output by means of other optical, acoustic, and / or tactile output elements, such as status LEDs, speakers, buzzers, vibration exciters, piezoelectric elements, or the like, for example by means of different colors, flashing, tones, vibration frequencies, amplitudes, or the like. It is also possible that the output unit 54 includes an output element configured as a display, on which at least one status message, the selected / set maximum operating time, and / or the remaining delay illumination duration are displayed. Alternatively, it is conceivable to output tactile signals perceptible to the user via the output element, particularly the aforementioned output element, configured as a vibration actuator, piezoelectric actuator, force feedback element, or the like.

[0038] In at least one method step 140 of method 100, when controlling or adjusting the delayed lighting function by means of the control or adjustment unit 28, signals, especially electrical or electronic signals, received by the communication interface 56 from the external controller 66, particularly from the mobile terminal device, for activating and / or parameterizing the delayed lighting function are considered. The communication interface 56 exchanges data between the external controller 66 and the control or adjustment unit 28 of the construction site lighting device 10. It is conceivable to control or adjust the delayed lighting function by means of an application installed on the mobile terminal device. Furthermore, it is conceivable that the communication interface 56 exchanges data with at least one other construction site lighting device 10, particularly one of the same type, particularly for controlling or adjusting that other construction site lighting device 10. Method 100 may have other method steps that are meaningful to those skilled in the art. Furthermore, for method 100, it is possible to... Figure 1 and Figure 2 The possible method steps derived from the description should also be considered as public.
