The invention claimed is: 1. A lighting system comprising: a plurality of lighting units, at least one lighting unit of the plurality of lighting units comprising: at least one light source; a memory for storing an identifier uniquely associated with the at least one lighting unit; and a processor
The invention claimed is: 1. A lighting system comprising: a plurality of lighting units, at least one lighting unit of the plurality of lighting units comprising: at least one light source; a memory for storing an identifier uniquely associated with the at least one lighting unit; and a processor configured to: (i) receive address identification data; (ii) compare the address identification data to at least a portion of the identifier, thereby generating a comparison value related to a comparison therebetween; and (iii) cause the at least one light source of the at least one lighting unit to maintain or alter its illumination state in response to the comparison value; and a system controller coupled to the plurality of lighting units, the system controller comprising: a compilation module for determining respective identifiers associated with the lighting units; and a detection apparatus operably coupled to the lighting units for monitoring illumination states thereof and communicating information associated with the illumination states to the compilation module. 2. The lighting system of claim 1, wherein the identifier is a pre-programmed multiple-bit binary number. 3. The lighting system of claim 1, wherein the at least one light source comprises a light-emitting diode. 4. The lighting system of claim 1, wherein the detection apparatus comprises a power sensing module coupled to the at least one lighting unit for (i) sensing power drawn by the at least one lighting unit in response to the comparison between the address identification data and at least a portion of the identifier; and (ii) generating an output signal representing the illumination state of the at least one lighting unit. 5. The lighting system of claim 4, wherein the power sensing module comprises: a sampling resistor for developing a sampled voltage in response to power drawn by the at least one lighting unit; and an operational amplifier operably connected to the sampling resistor for amplifying the sampled voltage to facilitate detection of the illumination state of the at least one lighting unit. 6. The lighting system of claim 1, wherein the compilation module is configured to direct the address identification data to the processor. 7. The lighting system of claim 1, wherein the compilation module is configured to determine the identifier of the at least one lighting unit based on the information associated with one or more illumination states of the at least one lighting unit. 8. A method for determining an identifier of a lighting unit, the lighting unit comprising at least one light-emitting diode (LED), the method comprising acts of: (a) providing address identification data to the lighting unit; (b) causing the lighting unit to read the address identification data; (c) comparing the address identification data to at least a portion of the identifier of the lighting unit to provide a comparison value; (d) causing the at least one LED to maintain or alter its illumination state in response to the comparison value; (e) monitoring the illumination state of the lighting unit to provide state information associated with the lighting unit; and (f) determining at least the portion of the identifier from the state information. 9. The method of claim 8, further comprising an act of mapping the identifier to the lighting unit. 10. The method of claim 8, wherein the lighting unit is operably coupled to a lighting unit controller, and further comprising an act of mapping the identifier to the lighting unit controller. 11. The method of claim 8, wherein the lighting unit is one of a plurality of lighting units, wherein the act of providing address identification data to the lighting unit comprises an act of providing address identification data to the plurality of lighting units, and wherein the act of monitoring the illumination state of the lighting unit comprises monitoring the illumination state of the plurality of lighting units. 12. The method of claim 11, wherein the act of monitoring the illumination state comprises an act of monitoring a power consumed by the plurality of lighting units, and wherein the method further comprises an act of determining a number of lighting units from the power consumed. 13. The method of claim 8, wherein the act of monitoring comprises an act of monitoring a power consumed by the lighting unit. 14. The method of claim 8, wherein the act of monitoring comprises, concurrent with the act of causing the at least one LED to maintain or alter its illumination state, an act of capturing an image of the lighting unit. 15. The method of claim 14, further comprising an act of associating the identifier with a location of the lighting unit. 16. The method of claim 8, wherein the identifier comprises a plurality of bits of data, and wherein the act of providing to the lighting unit address identification data comprises providing to the lighting unit an instruction associated with a selected and numbered bit of the plurality of bits, and wherein the act of comparing the address identification data to at least a portion of the identifier of the lighting unit comprises comparing the instruction to the selected and numbered bit of the identifier. 17. The method of claim 16, further comprising acts of: providing a binary search tree representing candidate identifiers; and progressing through the binary search tree in a manner responsive to the state information, until each of the plurality of bits of the identifier is determined. 18. The method of claim 8, wherein the act of causing the at least one LED to maintain or alter its illumination state comprises controlling at least one of a color and an intensity of the light emitted by the lighting unit.
