US Patent 11332064 Control of a directed light source

A directed light source supplies a light cone which is guided across a predefined area. A method for controlling the light source includes determining a movement of the light source; estimating an impending change in a section of the area illuminated by the light cone as a result of the determined movement; determining that the section will most likely be illuminated by the changed light cone for longer than predefined; and supplying a dimming signal for the light source.
