Abstract

A luminaire for emitting illumination to illuminate an environment, the luminaire being designed to rest on or fix to a surface; wherein the luminaire incorporates microphone apparatus comprising one or more microphones for capturing audio signals from the environment, and wherein the microphone apparatus is configured to provide the audio signals to a voice control algorithm on a signal processing apparatus in order to process one or more voice commands in the audio signals.

Claims

AMENDED CLAIMS received by the International Bureau on 11 June 2019 (11.06.2019)
1. A luminaire for emitting illumination to illuminate an environment, the luminaire being designed to rest on or fix to a surface; wherein the luminaire incorporates
microphone apparatus comprising one or more microphones for capturing audio signals from the environment, and wherein the microphone apparatus is configured to provide the audio signals to a voice control algorithm on a signal processing apparatus in order to process one or more voice commands in the audio signals; and
wherein the luminaire comprises a lamp shade, and the microphone apparatus is disposed in the lampshade.
2. The luminaire of claim 1, wherein the one or more microphones are disposed on an extreme outer edge of the lampshade.
3. The luminaire of any preceding claim, wherein the luminaire takes the form of a table lamp or a desk lamp, said surface being a table top of the table or a work surface of the desk respectively.
4. The luminaire of any of claims 1 to 3, wherein the luminaire takes the form of a floor lamp, said surface being a floor.
5. The luminaire of any of claims 1 to 3, wherein the luminaire takes the form of a ceiling mountable luminaire, said surface being a ceiling and the luminaire or base being designed to fix to the ceiling.
6. The luminaire of any of claims 1 to 3, wherein the luminaire takes the form of a wall mountable luminaire, said surface being a wall and the luminaire or base being designed to fix to the wall.
7. The luminaire of any preceding claim, wherein the microphone apparatus comprises multiple microphones, and the voice control algorithm to which the microphone apparatus is configured to provide the audio signals comprises a beamsteering algorithm for spatially targeting a source of the voice commands and/or avoiding one or more other sources.
8. The luminaire of any preceding claim, wherein the microphones are disposed in a regular array around an outer face or edge of the lampshade.
9. The luminaire of any preceding claim, wherein the voice Control algorithm to which the microphone apparatus is configured to provide the audio signals comprises an echo cancellation algorithm for cancelling echoes from the audio signals.
10. The luminaire of any preceding claim, comprising a controller configured to control the illumination based on controls signals receive back from the voice control algorithm in accordance with the voice commands.
11. The luminaire of claim 10, wherein the control which the controller is configured to perform in accordance with the voice commands comprises one or more of:
- switching the illumination on and/or off,
- dimming the elimination up and/or down, and/or
- controlling a colour of the illumination.
12. The luminaire of any preceding claim, wherein the signal processing apparatus on which the voice control algorithm is implemented is also incorporated in the luminaire.
13. The luminaire of any of claims 1 to 11, wherein the signal processing apparatus is external to the luminaire and luminaire comprises a communications interface, the microphone being configured to provide the audio signals to the voice control algorithm on the signal processing apparatus via said communications interface.
14. The luminaire of claim 12 or 13, wherein:
the luminaire comprises a base designed to rest on or fix to said surface, and a body part having a connector for accepting an light-emitting element for emitting said illumination; the body part being arranged so as when the base is resting on or fixed to said
29 surface in the manner for which it is designed and the light-emitting element is connected to the body part via the connector, the light-emitting element is held apart from the base and surface by the body part;
the connector takes the form of a standardized socket for powering the light- emitting element; and
the signal processing apparatus or communications interface, respectively, is implemented in a module which connects to the body part via the standardized socket and which comprises a further instance of the standardized socket into which the light-emitting element connects; such that the module is arranged to derive power for powering the signal processing apparatus or communications interface via the socket in the body part of the luminaire; and the light-emitting element can connect to the body part, and derive power from the body part for emitting said illumination, vicariously via the instance of the socket in the module.
15. The luminaire of claim 14, wherein the microphone apparatus is also retrofitted to the luminaire.
16. The luminaire of claim 15, wherein the lampshade is a removable part of the luminaire.
17. The luminaire of any preceding claim, wherein the voice control algorithm is configured to control, based on the voice commands captured via the luminaire, one or both of:
- an appliance other than the luminaire, and/or
- a service other than controlling the illumination.
18. The luminaire of claim 17, wherein the voice control algorithm is configured to control, based on the voice commands via the luminaire, one or both of:
- a home or office appliance other than the luminaire; and/or
- a service accessed via the Internet, other than for controlling the illumination.
30
19. The luminaire of any preceding claim, further comprising a speaker configured to output audible feedback on the processing of the voice commands.
