Abstract

An active lighting device is placed on a person's wrist to light a path that the person is taking. The device is preferably in the form of a wristwatch. The device includes first light sources, which are controlled by a control unit. The first light sources are placed on a portion of a case. Each first light source activated by the control unit can produce a light beam of different orientation from another first light source activated by the control unit. The device further includes a motion sensor connected to the control unit to determine the wrist movement of the person wearing the device in order to allow the control unit to select certain first light sources to be activated depending on the person's wrist movement in order to light the path to be followed in the same defined forward direction.
