Patent ID: 8499593

Claim:
An apparatus for waking up a user, the apparatus comprising a light source for producing a light effect comprising a light beam directed toward a user's head, the apparatus comprising means for displacing the light source in an upward (R u ) or downward (R d ) direction during a period of time, in order to change a position of the light effect toward or away from the user's head, wherein the means to displace the light source is adapted to displace the light source gradually along an amount of displacement during a wake-up period until reaching a final wake-up time, wherein the means to displace the light source is arranged to start displacing the light source at a start position, then continuously displacing the light source along the amount of displacement and to end displacing the light source at an end position, wherein the apparatus is adapted to change an intensity of a light effect by starting the light effect with a dim light-intensity at a beginning of the time period and increasing the intensity of the light effect during the time period until the light effect has the final intensity at the end of the time period.
