1. A headlamp comprising:
- a light source comprising one or more LED type diodes;
control means for controlling the geometry of the light beam of said light source in response to a control information or a control signal;
a control unit for generating said control information or said control signal;
wherein said headlamp is configured to be carried on a user'"'"'s head and allowing hand-free lighting for such user;
wherein said control unit comprises a image sensor included into said headlamp wherein said image sensor is configured for capturing an image of the scene being illuminated by said headlamp and said image sensor being further aligned with the axis of said LEDs, said image sensor generating at least one image arranged in pixels of the area illuminated by said light source and processing means for processing said image so as to generate said control information or said control signal.

14. A method for adjusting the light generated by a headlamp comprising one or more LEDs, comprising the steps of:
-
providing a headlamp comprising; a light source comprising one or more LED type diodes; control means for controlling the geometry of the light beam of said light source in response to a control information or a control signal; a control unit for generating said control information or said control signal; wherein said headlamp is configured to be carried on a user'"'"'s head and allowing hand-free lighting for such user; wherein said control unit comprises an image sensor included into said headlamp wherein said image sensor is configured for capturing an image of the scene being illuminated by said headlamp and said image sensor being further aligned with the axis of said LEDs, processing means for processing said image so as to generate said control information or said control signal, a controllable power unit for supplying power to the LED lamps and a control unit for controlling the light generated by the lamp generating an image arranged in pixels of the area illuminated by said light source by means of said image sensor included into said headlamp; storing said image in a storage memory; and processing of said image to generate said control information or said control signal to said controllable power unit. - View Dependent Claims (15)
