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 configured to receive a light bulb, the light bulb fixture comprising:

a housing having a socket configured to receive the light bulb and shield light bulbs other than the light bulb from radio frequency (RF) signals; 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 access the memory for the light bulb configuration information and process the light bulb configuration information to obtain settings for the light bulb to operate; and

a wireless transmitter operatively coupled to the memory and the configuration electronics module and configured to transmit the 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 the light bulbs other than the light bulb.

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

3. The light bulb fixture of claim 1, further comprising a power supply having a set of terminals for connection to a set of terminals of the light bulb to power the light bulb upon insertion of the light bulb into 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, wherein the wireless transmitter is configured to periodically transmit the light bulb the settings for the light bulb without being externally prompted.

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

a receiver that is connected to the memory; and

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

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

9. 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.

10. A light bulb fixture system comprising:

a light source; and

a light bulb fixture including;

a housing having a socket configured to receive the light source and shield light sources other than the light source from radio frequency (RF) signals; and

a control electronics module disposed in the socket housing and configured to control power to the light source, 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 access the memory for the light bulb configuration information and process the light bulb configuration information to obtain settings for the light source to operate; and

a wireless transmitter operatively coupled to the memory and the configuration electronics module and configured to transmit the RF signals, that include the settings for the light source, to the light source 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 the light sources other than the light source.

11. The light bulb fixture system of claim 10, the light source further comprising:

a conductor configured to contact a conductor in the socket in which the light source is received; and

wherein the control electronics module is configured to connect to the light source via the conductor.

12. The light bulb fixture system of claim 10, further comprising a tag reader configured to obtain confirmation information from a wireless memory tag.

13. The light bulb fixture system of claim 10, 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.

14. The light bulb fixture system of claim 10, wherein the control electronics module comprises a power feed circuit having a first set of terminal configured to connect to a second set of terminals upon insertion of the light source into a light bulb fixture.

15. The light bulb fixture system of claim 10, further comprising a wireless receiver configured to receive signals and decipher light bulb configuration information from the signals.

16. The light bulb fixture system of claim 15, wherein the wireless receiver is configured to receive the signals sent by a smart phone.

17. The light bulb fixture system of claim 15, wherein the wireless receiver is configured to receive near field communications (NFC) or Bluetooth signals.

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

inserting a light bulb into the light bulb fixture, wherein the light bulb fixture includes;

a housing having a socket configured to receive the light bulb and shield light bulbs other than the light bulb from radio frequency (RF) signals; and

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

accessing the memory, using the configuration module, for light bulb configuration information in response to the inserting of the light bulb into the light bulb fixture;

processing the light bulb configuration information, using the configuration module, to obtain settings for the light bulb to operate; and

transmitting the RF signals that include the settings for the light bulb, 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 the light bulbs other than the light bulb.

19. The method of claim 18, wherein the configuration information comprises one or more features selected from a group consisting of a device address, a device descriptor, a location, a light color, a light brightness, a light pattern, and on and off times.

20. The method of claim 18, wherein:

the configuration information comprises a unique identifier to enable the light bulb to obtain full configuration information from a remote configuration service; and

the unique identifier serves as a lookup key for the configuration information.
