Abstract

In one aspect, disclosed is an example method for use by a lighting device including a microphone and a light source, the method including: (i) receiving, by the lighting device via the microphone, an audio signal; (ii) decoding and extracting, by the lighting device, a lighting device control instruction from the received audio signal; and (iii) using, by the lighting device, at least the decoded and extracted lighting device control instruction as a basis to control operation of the light source.

First claim

The invention claimed is:

1 . A method for use by a lighting device comprising a microphone and a light source, the method comprising:
receiving, by the lighting device via the microphone, an audio signal comprising (i) audio data representing audio content and (ii) a lighting device control instruction configured to control operation of the light source such that the light source emits light in a manner that synchronizes the emitted light with a presentation of the represented audio content via a sound speaker; decoding and extracting, by the lighting device, a lighting device control instruction from the received audio signal; and using, by the lighting device, at least the decoded and extracted lighting device control instruction as a basis to control operation of the light source, thereby causing the light source to emit light in a manner that synchronizes the emitted light with the presentation of the represented audio content via the sound speaker; wherein the lighting device is configured to operate in a pairing mode, wherein the lighting device is configured to operate in a controlling mode, and wherein the lighting device is configured to operate at a given time in exactly one of the pairing mode or the controlling mode, the method further comprising: while operating in the pairing mode, detecting a model or type of the lighting device; and while operating in the controlling mode: using one or more predefined rules associated with the detected model or type of the lighting device to edit the lighting device control instruction such that the lighting device control instruction is compatible with the lighting device.

2 . The method of claim 1 , wherein the lighting device control instruction is encoded in the received audio signal as a watermark.

3 . The method of claim 1 , wherein the lighting device control instruction specifies a lighting device identifier, wherein the method further comprises:
decoding and extracting the lighting device identifier from the audio signal; determining a lighting device identifier of the lighting device; comparing the decoded and extracted lighting device identifier and the determined lighting device identifier, and based on the comparing, detecting a match between the decoded and extracted lighting device identifier and the determined lighting device identifier; responsive to detecting the match between the decoded and extracted lighting device identifier and the determined lighting device identifier, using at least the decoded and extracted lighting device control instruction as a basis to control operation of the light source.

4 . The method of claim 1 , wherein the audio data is encoded within a first frequency range of the audio signal, and the lighting device control instruction is encoded within a second frequency range of the audio signal, and wherein the first frequency range of the audio signal and the second frequency range of the audio signal are non-overlapping.

5 . The method of claim 4 , wherein the first frequency range of the audio signal is a human audible frequency range, and wherein the second frequency range of the audio signal is a human inaudible frequency range.

6 . The method of claim 1 , wherein the lighting device control instruction specifies a lighting parameter.

7 . The method of claim 6 , wherein the lighting parameter specifies a color or brightness level.

8 . The method of claim 1 , wherein using at least the decoded and extracted lighting device control instruction as a basis to control operation of the light source occurs without the lighting device being paired to an external controller.

9 . The method of claim 1 , wherein using at least the decoded and extracted lighting device control instruction as a basis to control operation of the light source occurs while the lighting device operates in the controlling mode.

10 . The method of claim 1 , further comprising:
detecting, using a camera, LiDAR, or RADAR device, motion of a person near the lighting device, wherein using, by the lighting device, at least the decoded and extracted lighting device control instruction as a basis to control operation of the light source comprises: using, by the lighting device, at least (i) the decoded and extracted lighting device control instruction, and (ii) the detected motion of the person near the lighting device, as a basis to control operation of the light source.

11 . A lighting device comprising a microphone and a light source, and configured to perform a set of acts comprising:
receiving, by the lighting device via the microphone, an audio signal comprising (i) audio data representing audio content and (ii) a lighting device control instruction configured to control operation of the light source such that the light source emits light in a manner that synchronizes the emitted light with a presentation of the represented audio content via a sound speaker; decoding and extracting, by the lighting device, a lighting device control instruction from the received audio signal; and using, by the lighting device, at least the decoded and extracted lighting device control instruction as a basis to control operation of the light source, thereby causing the light source to emit light in a manner that synchronizes the emitted light with the presentation of the represented audio content via the sound speaker; wherein the lighting device is configured to operate in a pairing mode, wherein the lighting device is configured to operate in a controlling mode, and wherein the lighting device is configured to operate at a given time in exactly one of the pairing mode or the controlling mode, the set of acts further comprising: while operating in the pairing mode, detecting a model or type of the lighting device; and while operating in the controlling mode: using one or more predefined rules associated with the detected model or type of the lighting device to edit the lighting device control instruction such that the lighting device control instruction is compatible with the lighting device.

12 . The lighting device of claim 11 , wherein the lighting device control instruction is encoded in the received audio signal as a watermark.

13 . The lighting device of claim 11 , wherein the lighting device control instruction specifies a lighting device identifier, and the set of acts further comprises:
decoding and extracting a lighting device identifier from the audio signal; determining a lighting device identifier of the lighting device; comparing the decoded and extracted lighting device identifier and the determined lighting device identifier, and based on the comparing, detecting a match between the decoded and extracted lighting device identifier and the determined lighting device identifier; and responsive to detecting the match between the decoded and extracted lighting device identifier and the determined lighting device identifier, using at least the decoded and extracted lighting device control instruction as a basis to control operation of the light source.

14 . The lighting device of claim 11 , wherein the audio data is encoded within a first frequency range of the audio signal, wherein the lighting device control instruction is encoded within a second frequency range of the audio signal, and wherein the first frequency range of the audio signal and the second frequency range of the audio signal are non-overlapping.

15 . The lighting device of claim 14 , wherein the first frequency range of the audio signal is a human audible frequency range, and wherein the second frequency range of the audio signal is a human inau
