Definitions

  • the present invention relates to a smart light bulb including an integral virtual assistant device with a voice user interface that is operable to communicate with a cloud-based virtual assistant software agent and perform operations by voice command.
  • Intelligent virtual assistant devices are known in the art and include voice command devices know as smart speakers.
  • a smart speaker has a voice user interface including several microphones and a speaker, through which a smart speaker user may verbally communicate with a cloud-based virtual assistant software agent running on a remote computer.
  • a smart speaker is normally activated by speaking a keyword, followed by a question or instruction in the form of a voice command. For example:“Assistant, what time is it?”,“Assistant, play a song” or“Assistant, turn the heating on”; where the keyword is“Assistant”.
  • microphones on the device listen for a keyword followed by a voice command.
  • the voice command is transmitted as a digital signal through a Wi-Fi® network to a cloud-based virtual assistant software agent; the digital signal is interpreted by the virtual assistant software agent and a reply digital signal is transmitted back through the Wi-Fi network to the smart speaker; the reply digital signal may include a synthesised voice message or other audio data which is broadcast through the smart speaker, and may also include an instruction for the smart speaker e.g. instructing the smart speaker to increase the volume of the speaker.
  • a user may send a voice command through a smart speaker to a cloud-based virtual assistant software agent, asking the virtual assistant software agent to adjust the controls on the smart speaker e.g.“Assistant, mute the microphones”, answer questions or play audio files through the smart speaker, make and receive voice over internet protocol (VOIP) telephone calls or send and receive voice messages through the smart speaker, remotely control electronic devices connected to the internet, create and edit digital documents including to-do lists and calendars, and set alarms or reminders to play on the smart speaker.
  • VOIP voice over internet protocol
  • a smart speaker To use a smart speaker in the home, it must normally be plugged into an electrical plug socket. This requirement has several drawbacks. Firstly, a smart speaker cannot easily be used in a room that does not have a plug socket. For example in a bathroom, toilet or hallway. Secondly, in certain rooms all available plug sockets may already be in use, for example in a kitchen or living room with a large number of electrical appliances. Furthermore, a smart speaker must normally be placed on one side of a room so as to be near a plug socket, but in doing so, it may be difficult to hear the smart speaker or control the smart speaker by voice command from the the opposite end of the room. Finally, a smart speaker must normally be placed near a plug socket and off the floor, on a tabletop or other flat surface, but if no such space is available, there may be no place to put a smart speaker.
  • a smart light bulb is a light bulb that allows lighting to be customised and controlled remotely. Smart light bulbs may be controlled remotely by voice command but to do so they must be paired with a smart speaker or another virtual assistant device with a voice user interface. This requirement has several limitations. Firstly, a smart light bulb cannot be controlled by voice command if it is not paired with a smart speaker or another virtual assistant device with a voice user interface. Secondly, the pairing process may be complicated, and if so, may require time and technical know-how to set up. Finally, certain smart light bulbs may not be compatible with certain smart speakers or voice controlled virtual assistant devices.
  • the present invention seeks to provide a smart light bulb including an integral virtual assistant device with a voice user interface that is operable to communicate with a cloud- based virtual assistant software agent and perform operations by voice command.
  • a smart light bulb as defined in claim 1 .
  • the light emitting elements are light emitting diodes (LEDs) and the lighting circuit includes one or more LED drivers and a LED control circuit.
  • the lighting circuit may also include one or more coloured LEDs or RGB LEDs operable to indicate the operational status of the smart light bulb.
  • the connector may take the form of a Bayonet type light bulb connector suitable for connection to a Bayonet type light bulb socket.
  • the connector may take the form of an Edison screw type connector suitable for connection to an Edison screw type light bulb socket.
  • the smart light bulb may be useable to ask a cloud based virtual assistant to perform voice command operations including, but not limited to, turning one or more of the light emitting elements on or off (see FIG. 12), adjusting the brightness or colour of the light emitted by the light emitting element, adjusting the volume of the speaker, muting or unmuting the microphone, answering question (see. FIG. 13) or playing audio files (see FIG. 14), making and receiving voice over internet protocol (VOIP) telephone calls (see FIG. 15, 16 & 17) or sending and receiving voice messages (see FIG. 18, 19 & 20), creating and editing digital documents including to-do lists and calendars (see FIG. 21), remotely controlling other electronic devices connected to the internet (see FIG. 22) and setting alarms or reminders to play on the speaker.
  • the smart light bulb may also include an acoustic reflector mounted on the body of the smart light bulb.
  • the smart light bulb may include a miniature video camera mounted on the bulb and operable to record video and send it to the control circuit which may include a processor operable to processes video and send it as a digital signal through the radio circuit to a cloud-based virtual assistant software agent.
  • the smart light bulb may be mounted in a ceiling light fitting with a Bayonet or Edison screw type light bulb socket. Therefore, the smart light bulb may be used in a room with a ceiling light fitting but no plug sockets, for example a hallway, bathroom ortoilet, thereby providing access to a virtual assistant in these rooms.
  • the smart light bulb may also provide a virtual assistant to a room that does not have a free plug socket or surface space available to place a smart speaker, providing that room has a ceiling light fitting suitable to mount the device.
  • the smart light bulb when mounted in a ceiling light fitting in the centre of a room, the smart light bulb is better positioned to detect voice commands and emit sound more evenly throughout a room, compared with a smart speaker placed by a wall near a plug socket.
  • the smart light bulb provides voice controlled lighting without the difficulties associated with pairing smart light bulbs with smart speakers or other voice controlled virtual assistant devices and furthermore, the light source provides virtual assistant functionality without the need of a separate smart speaker or voice controlled virtual assistant device.
