Abstract

An internet of things system having a smart light bulb and a smart fixture. The smart light bulb may be inserted into and connect with the smart fixture for power to the smart light bulb. The smart light bulb may be configured by reading configuration information from a memory in the smart fixture. As a whole, the system may have two or more smart light bulbs inserted in two or more smart fixtures, respectively. The two or more smart light bulbs may be interconnected with one another with communication links to make up a mesh network. Non-bulb devices may be connected to the mesh network.

Claims

1. A light bulb fixture comprising:

a housing having a socket configured to receive a light bulb having a unique identifier; and

a control electronics module disposed in the socket housing, the control electronics module including;

a memory configured to include light bulb configuration information;

a configuration electronics module operatively coupled to the memory and configured to;

receive the unique identifier from the light bulb;

access the memory in response to receiving the unique identifier; and

identify, from the light bulb configuration information in the memory, settings that include the unique identifier; and

a wireless transmitter operatively coupled to the memory and the configuration electronics module and configured to transmit RF signals that include the settings for the light bulb, to the light bulb received in the socket of the housing, wherein the wireless transmitter includes an RF antenna configured to transmit the RF signals having a shaped radiation pattern to avoid reception of the RF signals by light bulbs other than the light bulb.

2. The light bulb fixture of claim 1, wherein the control electronics module further comprises a power feed circuit having a first set of terminals and the light bulb fixture comprises a power supply having a second set of terminals for connection to the first set of terminals.

3. The light bulb fixture of claim 1, wherein the shaped radiation pattern of the RF signals is produced by a shield configuration of the socket.

4. The light bulb fixture of claim 1, wherein the wireless transmitter is configured to transmit the light bulb the settings for the light bulb in near field communication (NFC) signals.

5. The light bulb fixture of claim 1, wherein the wireless transmitter is configured to transmit the light bulb the settings for the light bulb in Bluetooth signals.

6. The light bulb fixture of claim 1, further comprising:

a receiver that is connected to the memory, wherein the receiver is configured to receive signals that contain information that adds to or changes the light bulb configuration information in the memory.

7. The light bulb fixture of claim 6, wherein the receiver is configured to receive the signals sent by a smart phone.

8. The light bulb fixture of claim 1, wherein the settings for the light bulb to operate comprise a device address, a device descriptor, and location information.

9. A light source fixture system comprising:

a light source having a unique identifier; and

a light source fixture comprising;

a housing having a socket configured to receive the light source; and

a control electronics module disposed in the socket housing, the control electronics module including;

a memory configured to include light source configuration information; and

a configuration electronics module operatively coupled to the memory and configured to;

receive the unique identifier from the light source;

access the memory in response to receiving the unique identifier; and

identify, from the light source configuration information in the memory, settings that include the unique identifier; and

a wireless transmitter operatively coupled to the memory and the configuration electronics module and configured to transmit RF signals that include the settings to the light source, wherein the wireless transmitter includes an RF antenna configured to transmit the RF signals having a shaped radiation pattern to avoid reception of the RF signals by light sources other than the light source.

10. The light source fixture system of claim 9, the light source further comprising a conductor configured to contact a conductor in the socket in which the light source is received, wherein the control electronics module is configured to connect to the light source via the conductor.

11. The light source fixture system of claim 9, wherein the light source comprises one or more LEDs and the light source includes a light source drive circuit comprising an LED drive circuit connected to the one or more LEDs.

12. The light source fixture system of claim 9, wherein the control electronics module further comprises a power feed circuit having a first set of terminals and the light source fixture comprises a power supply having a second set of terminals for connection to the first set of terminals.

13. The light source fixture system of claim 9, wherein the shaped radiation pattern of the RF signals is produced by a shield configuration of the socket.

14. The light source fixture system of claim 9, wherein the wireless transmitter is configured to transmit the settings to the light source in near field communication (NFC) signals.

15. The light source fixture system of claim 9, wherein the wireless transmitter is configured to transmit the settings to the light source in Bluetooth signals.

16. The light source fixture system of claim 9, control electronics module further comprising:

a receiver that is connected to the memory, wherein the receiver is configured to receive signals that contain information that adds to or changes the light source configuration information in the memory.

17. The light source fixture system of claim 16, wherein the receiver is configured to receive the signals sent by a smart phone.

18. A method of configuring a light bulb using a light bulb fixture, the method comprising:

inserting a light bulb having a unique identifier into the light bulb fixture, wherein the light bulb fixture includes;

a housing having a socket configured to receive the light bulb; and

a control electronics module disposed in the housing, the control electronics including a memory, an electronics module, and a wireless transmitter disposed in the housing;

receiving the unique identifier from the light bulb;

accessing light source configuration information in the memory in response to receiving the unique identifier;

identifying, from the light source configuration information, settings that include the unique identifier; and

transmitting RF signals that include the settings to the light bulb, wherein the wireless transmitter includes an RF antenna configured to transmit the RF signals having a shaped radiation pattern to avoid reception of the RF signals by light bulbs other than the light bulb.

19. The method of claim 18, wherein the shaped radiation pattern of the RF signals is produced by a shield configuration of the socket.

20. The method of claim 18, further comprising receiving signals that contain information that adds to or changes the light bulb configuration information in the memory.
