Abstract

Methods, systems and apparatuses for controlling and managing a plurality of luminaires are disclosed. One method includes sensing, by a sensor of each of the plurality of luminaires, light received by the sensor, communicating, by a device, with the plurality of luminaires by a device through light pulses, commissioning and calibrating, by the device, the plurality of luminaires using the communication, and placing, by the device, at least one of the plurality of luminaires on a floor plan through the communication with light pulses, wherein the at least one of the plurality of luminaires identifies itself over a network.

Claims

1. A method of controlling and managing a plurality of luminaires, comprising:

sensing, by a sensor of each of the plurality of luminaires, light received by the sensor;

communicating, by a device, with the plurality of luminaires through light pulses that are sensed by the sensors;

commissioning and calibrating the plurality of luminaires using the communication; and

placing, by the device, at least one of the plurality of luminaires on a floor plan through the communication with light pulses, wherein the at least one of the plurality of luminaires identifies itself over a network;

collecting data from the plurality of luminaires;

using the collected data to determine an adjacency of lights and other devices; and

dynamically placing the plurality of lights and other device into zones and binding human interfaces to the zones; and

dynamically configuring the device to control the zones, wherein at least one of the human interfaces comprises the device.

2. The method of claim 1, wherein using light levels to confirm the location of the PDA comprises coordinating flashing of successive locations of lights.

3. The method of claim 1, further comprising establishing a target light sensor reading at a time of initial commissioning of the plurality of luminaires, and comparing current light readings with the target light sensor reading for calibrating each sensor at a ceiling versus light readings at a work surface.

4. The method of claim 3, wherein the current light readings with the target light sensor reading are compared at a predetermined frequency.

5. The method of claim 3, further comprising incrementing or decrementing power supplied to the plurality of luminaires depending on an aggregate difference between the current light readings with the target light sensor reading.

6. The method of claim 1, further comprising determining occupancy utilizing low-cost cameras.

7. The method of claim 6, further comprising generating pictures of floors below the cameras, and sensing occupancy by detecting changes in images produced by the cameras.

8. The method of claim 7, further comprising system managers sharing the pictures, and creating comprehensive images of a building floor based on the shared pictures.

9. A The method of claim 2,

wherein the device comprises a calibration device, and light levels are used to confirm a location of the calibration device.

10. The method of claim 9, wherein the calibration device comprises a personal digital assistant (PDA).

11. A system for managing a lighting, comprising:

a plurality of luminaires, wherein a sensor of each of the plurality of luminaires senses light received by the sensor;

a device, wherein the device is operative to;

communicate with the plurality of luminaires through light pulses that are sensed by the sensors; and

commission and calibrate the plurality of luminaires using the communication; and

place at least one of the plurality of luminaires on a floor plan through the communication with light pulses;

wherein the at least one of the plurality of luminaires identifies itself over a network; and

wherein the network is operative to;

collect data from the plurality of luminaires;

use the collected data to determine an adjacency of luminaires; and

dynamically place the plurality of luminaires into zones and binding human interfaces to the zones; and

dynamically configure the device to control the zones, wherein at least one of the human interfaces comprises the device.

12. The system of claim 11, wherein using light levels to confirm the location of the PDA comprises coordinating flashing of successive locations of lights.

13. The system of claim 11, further comprising establishing a target light sensor reading at a time of initial commissioning of the plurality of luminaires, and comparing current light readings with the target light sensor reading,

to efficiently manage the plurality of lights and devices.
