Lighting control system responsive to ambient lighting conditions
A controller, method and system, for controlling lighting responsive to ambient lighting conditions are described. In particular, disclosed is illumination controller ( 110 ) for controlling illumination of a workspace near a display ( 253 ). The illumination controller includes a memory device ( 113 ) storing a user's preference for illumination of the workspace; a processor ( 111 ) accessing the user's preference in the memory device; and an interface ( 112 ) between the processor and an electronic sensor ( 231 ) located proximate to the display, which collects a reading from the electronic sensor. The processor compares the reading with the user's preference, and sends a command to at least one luminaire ( 241 ) to adjust the illumination of the workspace. The electronic sensor can be, for example, a photosensor, an occupancy sensor, an orientation sensor, or a location sensor. In some embodiments, the interface collects the reading from the electronic sensor via a wireless communication link.
1. An illumination controller for controlling illumination of a workspace near a display, the illumination controller comprising:
a memory device storing a user's preference for illumination of the workspace;
a processor accessing the user's preference in the memory device;
an interface between the processor and an electronic sensor located proximate to the display, the interface collecting a reading from the electronic sensor;
the processor operating to discover wirelessly the electronic sensor,
discover at leas one luminaire in proximity to the electronic sensor and
create a sensor-luminaire map which maps each electronic sensor with one or more luminaire;
wherein the processor compares the reading with the user's preference, and sends a command to the at least one luminaire to adjust the illumination of the workspace.
2. The illumination controller of claim 1 , wherein the electronic sensor is a photosensor, an occupancy sensor, an orientation sensor, or a location sensor.
3. The illumination controller of claim 1 , wherein the interface collects the reading from the electronic sensor via a wireless communication link.
4. The illumination controller of claim 1 , wherein the interface identifies the electronic sensor before collecting the reading.
5. The illumination controller of claim 1 , wherein the display is a display of a computer.
6. The illumination controller of claim 1 , wherein the electronic sensor is attached to the display.
