BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a diagram that shows an overall setup of the present arrangement;
FIG. 2 is a diagram of a low power transmitter in a socket and a transmitter or radio that may be in control electronics; and
FIG. 3 is a diagram of an internet of things system having a mesh network of bulbs.



DESCRIPTION
The present system and approach may incorporate one or more processors, computers, controllers, user interfaces, wireless and/or wire connections, and/or the like, in an implementation described and/or shown herein.
This description may provide one or more illustrative and specific examples or ways of implementing the present system and approach. There may be numerous other examples or ways of implementing the system and approach.
Aspects of the system or approach may be described in terms of symbols in the drawing. Symbols may have virtually any shape (e.g., a block) and may designate hardware, objects, components, activities, states, steps, procedures, and other items.
A core element of IoT devices is that they may need to be configured, such as being programmed with a device address, device descriptor, location information and possibly other installation dependent settings. When a device is being replaced, it may take time and effort to configure the replacement part. This effort may add to the total cost of ownership. As the number of light bulbs is high in a building, the cost may be exceptionally large for light fixtures and light bulbs in particular.
A memory chip may be added to a light bulb socket or fixture. The light bulb may then read/write the memory once installed into a resulting smart socket or fixture. A broken light bulb can now be easily removed and a spare light bulb installed. The spare light bulb may simply read the previous configuration settings from the memory in the smart light fixture or socket.
The memory chip may be a two or single wire memory. The connection to the bulb could occur through contacts. Alternatively, a wireless memory tag may be affixed to the smart socket or light fixture that can be read by the light bulb (e.g., an RFID tag reader in the light bulb and an RFID tag in the fixture or socket).
The present device or system may have a smart socket that provides information for the smart light bulb. The smart light bulb may obtain information from an external location, i.e., a smart socket. The smart socket may provide support for the smart light bulb.
FIG. 1 is a diagram that shows an overall setup of the present arrangement. Item 11 may be a socket housing. Item 12 may be a socket thread for the threaded base of light bulb 21. Lines 15 and 16 may provide the phase (hot) and neutral (e.g., ground) inputs, respectively, of a power feed from a live voltage. A configuration electronics 14 may incorporate a low power RF transmitter, memory, receiver and a processor and be connected to lines 15 and 16 for power. Control electronics 22 of the IoT or smart light bulb 21 may be situated in a structure of bulb 21.
FIG. 2 is a diagram of example circuitry 10 for smart socket or fixture 11 and smart light bulb 21. Various versions of circuitry 10 may not necessarily incorporate all of the components shown which depend on the design and operations desired or needed from the circuitry.
Socket 11 may incorporate a control electronics module 62. Module 62 may have a power supply 41 connected to a power source 63 via line 15 (phase) and line 16 (neutral). A configuration electronics module 14 of module 62 may have a memory 64 connected to it. Memory 64 may store various kinds of configuration information for the smart light bulb 21. Configuration information may be received by a receiver 65 via an antenna 66. The wireless transmit power can be curtailed to the point that only light bulbs in immediate vicinity are able to receive the configuration. This assures that light bulbs spaced apart can maintain their individual settings. In support of this, the RF antenna of the configuration electronics module 14 can have an antenna with a shaped radiation pattern to avoid reception of RF signals by nearby light bulbs. This for example can be achieved by having the outer socket housing 11 act as a shield. The light bulb can query the configuration information from configuration electronics module 14. Alternatively, configuration module 14 can periodically transmit the configuration information without any external trigger. Configuration information could be received via a wire rather than a wireless medium. The wireless medium may be classic RF, light, or the like. Configuration information may instead be received via optical fiber instead.
Configuration information may go to configuration electronics module 14, which processes the information that is sent out via a transmitter 42 and antenna 43 to smart light bulb 21. Transmission may be via RFID devices in control electronics module 62 of smart socket 11 and control electronics 22 of smart light bulb 21. Alternatively, transmission of configuration information to smart light bulb 21 may be via wire or other media.
Power supply 41 may provide power to configuration electronics module 14, transmitter 42 and receiver 65. Configuration information may have settings that may be provided to configuration electronics module 14 and memory 64. Memory 64 may be a chip that could be replaced with another chip with different configuration information.
Besides power supply 41, transmitter 42, configuration electronics module 14, memory 64 and receiver 65 may be a part of control electronics module 62. Other components may likewise be a part of module 62.
A socket or insertion mechanism 12 for screwing or plugging in smart light bulb 21 may have contacts 55 and 56 for connecting lines 15 and 16, respectively, from power source 63 to a power supply 44 of control electronics module 22. Power supply 44 may provide power to a configuration electronics module 67, receiver 45, transmitter 68, and LED drive circuit 47. Other components may be powered by power supply 44.
As an example of transmitting configuration information from smart socket or fixture 11, transmitter 42 via antenna 43 may send out or emanate signals from configuration electronics module 14 and memory 64 that are detected by receiver 45 via antenna 46. The signals may go to configuration electronics module 67 which processes the signals for LED drive circuit 47, which may control the power from power supply 44 to LED 48 in accordance with configuration information. LED 48 may be regarded as a primary light source in bulb 21. Light source 48 may be another kind of source (e.g., fluorescent, incandescent, or other kind of source).
Control electronics 22 may incorporate a transmitter 68 and antenna 69 for purposes of communicating information back to smart socket 11, or to other smart bulbs and/or smart fixtures, such as in a mesh network. Components may be added or left out of control electronics module 22, or bulb 21 in general.
FIG. 3 is a diagram of an IoT mesh network system. Between each light bulb 21 and its socket 11 may be a low power short range configuration link 52. There may be a mesh network 51 among the light bulbs 21. Thermostat 53 and switch 54 may be other non-bulb devices in the IoT system. For instance, the IoT system may incorporate a mobile device 55. Also, a gateway 56 may be situated in the IoT system. Alternatively, there may be a mesh network 51 among the smart sockets or fixtures 11 using appropriate components present in each of the smart fixtures 11 as shown in FIG. 2, or adding them to each of smart fixtures 11 so as to achieve the mesh network among the fixtures 11.
The IoT mesh network may have two or more smart sockets. Two or more smart light bulbs may be inserted in the two or more smart sockets, respectively. The two or more smart light bulbs may be interconnected with one another with communication links. Each smart light bulb may have an exclusive connection with a smart socket in which the smart light bulb is inserted.
To recap, an internet of things (IoT) smart light bulb system may incorporate a smart fixture, a smart light bulb that can be inserted into and connect to the smart fixture for power to the smart light bulb, and a memory situated in the smart fixture. The smart light bulb may be configured by reading configuration information from the memory in the smart fixture.
The smart light bulb may be connected to the memory by a contact between conductors from the smart fixture and the smart light bulb, upon the insertion of the smart light bulb into the smart fixture.

The memory may contain configuration information that can be provided via the wireless transmitter to the wireless receiver and the control electronics module, respectively. The configuration information may be for configuring the light source.
If the smart bulb is replaced with a new smart bulb, the new smart bulb may be configured with the configuration information in the memory that is read by the wireless transmitter and transmitted to the wireless receiver which in turn may provide the configuration information to the control electronics module for configuring the light source.
The configuration information may incorporate one or more features of the smart bulb selected from a group comprising a device address, a device descriptor, location, light color, light brightness, light patterns, and on and off times.
