Lighting Fixture Remote Microphone Voice Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems with built-in microphones have limited coverage areas, making it necessary to be within a certain range for voice commands to be successfully received and executed, which restricts their functionality in larger spaces.
Innovation Solution
Incorporating a wireless transceiver and remote microphone devices that can receive voice commands and transmit audio streams to a cloud server, allowing for expanded coverage and remote control of lighting fixtures and other devices through a cloud voice service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a built-in microphone is used in a lighting fixture, then the lighting fixture can receive voice commands, but the coverage area is limited to a certain range
Solution Approach 1:
The patent divides the voice reception function into separate components: a remote microphone device positioned away from the lighting fixture and a wireless transceiver system. This segmentation allows the microphone to be located in a different position, expanding the coverage area while maintaining the lighting fixture's functionality.
Solution Approach 2:
The patent introduces a wireless transceiver as an intermediary between the remote microphone device and the lighting fixture. The transceiver receives audio signals from the remote microphone and wirelessly transmits them to the lighting fixture, enabling voice command reception beyond the traditional built-in microphone range.
2Adaptability or versatility
If the microphone is integrated into the lighting fixture, then the structure is simple, but the voice command reception is restricted to nearby users
Solution Approach 1:
The patent creates a multi-functional system where the remote microphone device can be positioned anywhere in the environment, and the wireless transceiver handles both reception and transmission of audio signals. This universal design allows the system to adapt to various spatial configurations and usage scenarios while maintaining relatively simple individual components.
3Area of stationary object
If a remote microphone device is added to expand coverage, then the coverage area increases, but the device complexity increases
Solution Approach 1:
The patent extracts the microphone function from the lighting fixture and places it in a separate remote microphone device. This extraction allows the coverage area to be expanded by positioning the microphone optimally in the environment, while the lighting fixture itself remains relatively simple, only requiring a wireless transceiver receiver.

AI summary
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.
