Abstract
The invention relates to a wake up stimulus control system, comprising a control unit () arranged to receive a user-determinable wake up time input and to control at least one stimulus source (), a coupling for operably coupling at least one stimulus source () to said control unit, wherein the stimulus source () is controllable by the control unit () in such a way that the stimulus source () provides a gradually increasing stimulus output in dependence on said input wake up time, at least during a time period before the input wake up time, and at least one stimulus sensor () that is operably coupled to the control unit (). The sensor allows a much better control of the supplied stimulus level to account for various ambient influences. The stimulus is preferably light. The invention also provides a socket, a stimulus source and a control unit for use in the system.
