AMBIENT LIGHT CONTROL
First Claim
1. A control device for use in an ambient light control system for controlling ambient light entering a space through an opening, the control device comprising:
- an ambient light prediction unit for providing ambient light prediction values, wherein an ambient light prediction value is a prediction of an ambient light property at the opening,an ambient light adjusting unit for providing, at different ambient light adjusting time points, an ambient light adjusting signal depending on the ambient light prediction values for an upcoming ambient light prediction time period, wherein the ambient light adjusting unit is adapted to provide the ambient light adjusting signal at several ambient light adjusting time points, wherein the ambient light adjusting signal is adapted for use by an ambient light modifying element for modifying the entering of ambient light into the space through the opening wherein the ambient light adjusting signal at a current ambient light adjusting tine point is provided depending on the ambient light prediction values for the upcoming ambient light prediction time period, wherein the upcoming ambient light prediction time period is the tie period from the current ambient light adjusting time point until the next ambient light adjusting tie point.

Abstract
The invention relates to a control device (10) for use in an ambient light control system (20) for controlling ambient light entering a space (1) through an opening (2). An ambient light prediction unit (11) provides ambient light prediction values, which are predictions of an ambient light property at the opening (2). An ambient light adjusting unit (12) provides, at different ambient light adjusting time points, an ambient light adjusting signal depending on the ambient light prediction values for an upcoming ambient light prediction time period. The ambient light adjusting signal is adapted for use by an ambient light modifying element (22) for modifying the entering of ambient light into the space (1) through the opening (2). By taking the predicted ambient light conditions at the opening (2) into account, necessary adjustments can be made at temporally spaced ambient light adjusting time points, resulting in fewer disturbances of the users.
