Abstract
The present invention relates to a light controller () configured to control a lighting system () for emitting light, comprising an image sensor () configured to capture an image of an activity area, and a control unit () configured to received the image, to detecting movement within the activity area, and to provide an activation signal for switching on a light source () of the lighting system (), wherein the control unit () is further configured to provide a deactivation signal for switching off the light source () after a computed time period if no movement is detected within the activity area, the computed time period being based on a computed distance between a predetermined position within the activity area and a position of the latest detected movement within the activity area. The present invention provides advantages in relation to e.g. optimized 'on time' of the light source of the lighting system thereby providing an improvement in relation to the total energy consumption of the lighting system.
