Light device and method for controlling a light device
First Claim
1. A lighting device comprising:
- at least one light module which has a front side and a rear side and a front lighting means arranged for emitting light from the front side, a rear lighting means arranged for emitting light from the rear side, and a control unit,wherein the control unit of the at least one light module is arranged to adjust the front lighting means and the rear lighting means,wherein the control unit of the at least one light module comprises an interface, via which the lighting device can be connected to a calibration device,wherein the control unit of the at least one light module is designed to receive a calibration signal from the calibration device via the interface, andwherein the control unit of the at least one light module is arranged to calibrate the at least one light module to a pre-adjustable light level by evaluating the calibration signal, to dynamically adjust the front lighting means for displaying information, and to adjust the rear lighting means to the dynamically adjusted front lighting means such that the calibrated light level is constant.

Abstract
A light device comprises at least one light module having a front side and a rear side, as well as a lighting means arranged for emitting light from the front side, a lighting means arranged for emitting light from the rear side, and a control unit. The control unit is configured for adjusting the front-side lighting means and the rear-side lighting means. In particular, the control unit is configured to calibrate the light module to a light level that can be preset, to dynamically adjust the front-side lighting means for the display of information, and to adjust the rear-side lighting means such that it is adapted to the dynamically adjusted front-side lighting means, so that the calibrated light level is constant. In this way, the light device can influence the lighting properties in a target area in such a way that an impairment of the illumination of the target area is minimal for displaying the information even with varying lighting properties of the front lighting means.
