Abstract
The present application relates to a lighting control apparatus (2) configured to control light emitted from at least one light emitting device (4) using one or more control signals (6). The apparatus (2) uses data (10) associated with a physiological or cognitive state of a user to determine an appropriate control signal (6) to send to the light emitting device (4) when light control input data (8) is provided via a light control input device (30). The apparatus (2) is used in conjunction with a network of lights providing different combinations of intensity and hue. Also presented is a method (14) for controlling light emitted from at least one light emitted device (4) using one or more control signals (6).
