Abstract

A lighting system with expanded coverage voice operation includes a lighting fixture that includes a wireless transceiver. The lighting system further includes a remote microphone device configured to receive a voice and to transmit wirelessly an audio stream generated from the voice. The lighting fixture is configured to receive the audio stream from the remote microphone device via the wireless transceiver and to transmit the audio stream to a cloud server.

First claim

What is claimed is:

1. A lighting system with expanded coverage voice operation, comprising:
a lighting fixture comprising a wireless transceiver, wherein the lighting fixture is located in a first area; and
a remote microphone device configured to receive a voice and to transmit to the lighting fixture an audio stream generated from the voice wirelessly, wherein the remote microphone device is located in a second area that is different from the first area, wherein the lighting fixture is configured to receive the audio stream from the remote microphone device via the wireless transceiver and to transmit the audio stream to a cloud server that provides a cloud voice service, wherein the lighting fixture is configured to receive one or more instructions from the cloud server, wherein the one or more instructions are generated by the cloud server based on the audio stream, and wherein one or more devices are controlled based on the one or more instructions received from the cloud server.

2. The lighting system of claim 1 , wherein the remote microphone device is a light dimmer or a wall outlet.

3. The lighting system of claim 1 , wherein the lighting fixture is configured to control a light source of the lighting fixture based on the one or more instructions.

4. The lighting system of claim 1 , wherein the lighting fixture comprises a built-in microphone.

5. The lighting system of claim 4 , wherein the lighting fixture is configured to receive a second voice via the built-in microphone and to transmit to the cloud server a second audio stream generated from the second voice.

6. The lighting system of claim 4 , wherein the lighting fixture is configured to transmit a microphone wake-up command to the remote microphone device in response to receiving the wake-up voice command.

7. The lighting system of claim 1 , wherein the remote microphone device is configured to receive a microphone wake-up command and to start listening for a sound in response to the microphone wake-up command.

8. The lighting system of claim 7 , wherein the remote microphone device is configured to enter a standby state if the sound is undetected by the remote microphone device within a wait time period after receiving the microphone wake-up command.

9. The lighting system of claim 1 , further comprising a second lighting fixture configured to receive the one or more instructions from the cloud server.

10. A lighting system with expanded coverage operation, comprising:
a lighting fixture comprising a wireless transceiver;
a first remote microphone device configured to receive a first sound and to transmit wirelessly to the lighting fixture a first signal generated from the first sound, wherein the lighting fixture is configured to receive the first signal from the first remote microphone device via the wireless transceiver and to transmit a second signal generated from the first signal to a cloud server; and
a second remote microphone device configured to receive a second sound and to transmit wirelessly to the lighting fixture a third signal generated from the second sound, wherein the lighting fixture is configured to receive the third signal from the second remote microphone device via the wireless transceiver and to transmit to the cloud server a fourth signal generated from the third signal, wherein the lighting fixture, the first remote microphone device, and the second remote microphone device are in different rooms from each other, wherein the lighting fixture is configured to receive instructions from the cloud server, and wherein the instructions are generated by the cloud server based on the second signal and the fourth signal received from the lighting fixture.

11. The lighting system of claim 10 , wherein the cloud server is configured to identify the first sound by processing the second signal and generate the instructions based on identifying the first sound.

12. The lighting system of claim 10 , wherein the cloud server is configured to identify the second sound by processing the fourth signal and to generate the instructions based on identifying the second sound and wherein a third device is configured to receive the instructions from the cloud server.

13. The lighting system of claim 10 , wherein the lighting fixture comprises a built-in microphone and a built-in speaker, wherein the lighting fixture is configured to receive a third sound via the built-in microphone and transmit a third signal generated from the second sound to the cloud server, wherein the lighting fixture is configured to receive a response from the cloud server and provide the response via the speaker, and wherein the response is generated by the cloud server by processing the third signal.

14. The lighting system of claim 13 , wherein the lighting fixture is configured to output an inverted ambient noise sound via the built-in speaker and where the inverted ambient noise sound is generated by the lighting fixture by inverting an ambient noise received by the built-in microphone.

15. A lighting system with expanded coverage voice operation, comprising:
a lighting fixture comprising a wireless transceiver; and
a remote microphone device configured to receive a voice and to transmit an audio stream generated from the voice wirelessly, wherein the lighting fixture is configured to receive the audio stream from the remote microphone device via the wireless transceiver and to transmit the audio stream to a cloud server that provides a cloud voice service, wherein the lighting fixture is configured to transmit a microphone wake-up command to the remote microphone device based on a wake-up voice command received by the lighting fixture via a built-in microphone of the lighting fixture, and wherein the remote microphone device is configured to receive the microphone wake-up command, to start listening for a sound in response to the microphone wake-up command, and to enter a standby state if the sound is undetected by the remote microphone device within a wait time period after receiving the microphone wake-up command.

16. The lighting system of claim 15 , wherein the remote microphone device is a lighting control device or a wall outlet.

17. The lighting system of claim 16 , wherein the lighting control device is a light dimmer.

18. The lighting system of claim 15 , wherein the lighting fixture is configured to control a light source of the lighting fixture based on the one or more instructions received from the cloud server.

19. The lighting system of claim 15 , further comprising a second remote microphone device and a second lighting fixture, wherein the second remote microphone is configured to receive a second voice and to transmit to the lighting fixture wirelessly a second audio stream generated from the second voice and wherein the second lighting fixture is configured to receive the one or more instructions from the cloud server and to operate based on the one or more instructions.
