Abstract

A smart lamp system and method for monitoring a status of LEDs. The system can provide LED status monitoring using a logic controller communicating with at least one strip of LEDs. The system can utilize the logic controller to assign a unique identifier (ID) to the at least one strip of LEDs based on a physical position of a plurality of dual-inline package (DIP) switches incorporated within a smart lamp housing. The system can provide a hardware architecture to interface the logic controller with a power-line communication (PLC) transceiver. The system can establish a communication protocol between the PLC transceiver and a PLC receiver to efficiently communicate the statuses of the LEDs. The logic controller can generate a payload including a binary representation of the unique ID of the smart lamp and the statuses of the LEDs and transmit the payload to the PLC transceiver.

First claim

What is claimed is:

1. A smart lamp system configured to monitor a status of light-emitting diodes (LEDs), comprising:
a power-line communication (PLC) receiver configured to receive data communication signals via power-line communication;
a first smart lamp for controlling and monitoring statuses of a first LED strip, including:
a first plurality of dual-inline package (DIP) switches for representing an identifier of the first LED strip; and
a first power-line transceiver configured to transmit the status of the first LED strip and the identifier to the PLC receiver via power-line communications.

2. The smart lamp system of claim 1 , further comprising a processor coupled to the first plurality of DIP switches, the first power-line transceiver, and the first LED strip, configured to monitor the status of the first LED strip.

3. The smart lamp system of claim 2 , wherein the processor is further configured to monitor the statuses of the first LED strip, by performing the steps of:
monitoring voltage, current, and the DIP switch positions; and
transmitting a communications payload to the power-line transceiver.

4. The smart lamp system of claim 1 , wherein the identifier corresponds with a unique identifier (ID) for the first smart lamp, left or right position of the first smart lamp, or establishes a time delay for message transmission.

5. The smart lamp system of claim 1 , wherein the first plurality of DIP switches includes at least seven DIP switches.

6. The smart lamp system of claim 1 , wherein the status includes the first LED strip is operable, the first LED strip is inoperable, a portion of the first LED strip is operable, or a portion of the first LED strip is inoperable.

7. The smart lamp system of claim 2 , wherein the processor is further configured to perform the step of assigning a smart lamp configuration based on the first DIP switch positions.

8. The smart lamp system of claim 2 , wherein the processor is further configured to perform the step of generating a communications payload based on the statuses and the DIP switch positions.

9. The smart lamp system of claim 2 , wherein the processor is further configured to perform the step of detecting an activation failure.

10. The smart lamp system of claim 1 , wherein the PLC receiver includes at least one dual polarity terminal.

11. A smart lamp system configured to monitor a status of light-emitting diodes (LEDs), comprising:
a power-line communication (PLC) receiver configured to receive data communication signals via power-line communication;
a first smart lamp for controlling and monitoring statuses of a first LED strip, including:
a first plurality of dual-inline package (DIP) switches for representing a first identifier of the first LED strip; and
a first power-line transceiver configured to transmit the status of the first LED strip and the identifier to the PLC receiver via power-line communications; and

a second smart lamp for controlling and monitoring statuses of a second LED strip, including:
a second plurality of dual-inline package (DIP) switches for representing a second identifier of the second LED strip; and
a second power-line transceiver configured to transmit the status of the second LED strip and the second identifier to the PLC receiver via power-line communication.

12. The smart lamp system of claim 11 , further comprising a first processor coupled to the first plurality of DIP switches, the first power-line transceiver, and the first LED strip, configured to monitor a first status of the first LED strip.

13. The smart lamp system of claim 12 , further comprising a second processor coupled to the second plurality of DIP switches, the second power-line transceiver, and the second LED strip, configured to monitor a second status of the second LED strip.

14. The smart lamp system of claim 13 , wherein the first and second processors are further configured to monitor the first and second statuses of the first and second LED strips, by performing the steps of:
monitoring voltage, current, and the respective DIP switch positions; and
transmitting a communications payload to the power-line transceiver.

15. The smart lamp system of claim 11 , wherein the first identifier corresponds with a unique identifier (ID) for the first smart lamp, left or right position of the first smart lamp, or establishes a time delay for message transmission.

16. The smart lamp system of claim 13 , wherein the first and second statuses includes an indication that the first and second LED strips are operable, the first and second LED strips are inoperable, or the first LED strip is operable or the second LED strip is inoperable.

17. The smart lamp system of claim 13 , wherein the first power-line transceiver includes a first connection and a second connection and the second power-line transceiver includes a third connection and a fourth connection.

18. The smart lamp system of claim 11 , wherein the first connection can be coupled to a first terminal of a surge panel and the second connection can be coupled to a second terminal of the surge panel.

19. The smart lamp system of claim 18 , wherein the third connection can be coupled to a third terminal of a surge panel and the fourth connection can be coupled to the second terminal of the surge panel.
