Dual Bluetooth Module Lighting Device for Wireless Audio Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices with audio playing functions are not conveniently controlled wirelessly, as they often require expensive Bluetooth modules supporting large-capacity external flash drives and iOS-compatible control chips, and using a 2.4G remote controller is not as convenient as using a user device with Bluetooth functionality.
Innovation Solution
A wirelessly-controlled lighting device with two Bluetooth modules, one for receiving control signals to manage lighting and another for receiving audio data, allowing simultaneous control of lighting and audio playing without the need for high-capacity Bluetooth modules or iOS-compatible chips, using Bluetooth Low Energy (BLE) and Advanced Audio Distribution Profile (A2DP) technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single Bluetooth module is used to control both lighting and audio functions, then device complexity is reduced, but control reliability deteriorates due to signal interference between control signals and audio data
Solution Approach 1:
The patent divides the Bluetooth communication function into two separate modules: one dedicated to control signals for lighting and another dedicated to audio data transmission. This segmentation prevents signal interference between control commands and audio streams, ensuring reliable operation of both functions simultaneously.
Solution Approach 2:
The patent introduces an antenna switching mechanism that acts as an intermediary between the two Bluetooth modules and the shared antenna. This mediator allows selective connection of different Bluetooth modules to the antenna at different times, preventing direct signal conflict while enabling both functions to operate reliably.
2Quantity of substance
If expensive Bluetooth modules supporting large-capacity external flash drives are used, then audio storage capacity is improved, but device cost increases
Solution Approach 1:
The patent leverages the external device's (smartphone/tablet) existing storage capacity and audio files to provide the lighting device with unlimited audio storage capability. The lighting device only needs a Bluetooth audio receiver module, while the user's personal device serves as the storage repository, eliminating the need for expensive internal storage hardware.
Solution Approach 2:
The patent replaces expensive high-capacity storage hardware with a simple Bluetooth audio receiver module that streams audio data wirelessly. This approach uses the user's existing digital library rather than requiring physical storage media, significantly reducing hardware costs while maintaining full audio functionality.
3Adaptability or versatility
If iOS-compatible control chips are added to enable smartphone control, then adaptability is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses standard Bluetooth communication protocols that are universally supported by all smartphones regardless of operating system (iOS, Android, etc.). This universal approach eliminates the need for proprietary iOS-compatible chips while maintaining full compatibility with all major mobile platforms, simplifying the device architecture.
4Ease of operation
If a 2.4G wireless module with special remote controller is used, then lighting control function is improved, but ease of operation deteriorates compared to using built-in Bluetooth
Solution Approach 1:
The patent employs a Bluetooth module as an intermediary that enables direct communication between the lighting device and the user's smartphone. This eliminates the need for a separate physical remote controller, allowing the user to leverage their familiar smartphone interface for controlling lighting functions, thereby improving ease of operation.

AI summary
A wirelessly-controlled lighting device and method with an audio playing function is provided. The wirelessly-controlled lighting device includes a lighting assembly (101, 201), an audio playing module (104, 204), a first Bluetooth module (102, 202) connecting with the lighting assembly (101, 201) and the audio playing module (104, 204) and a second Bluetooth module (103, 203) connecting with the audio playing module (104, 204). The first Bluetooth module (102, 202) is configured to receive a control signal from an external device (107, 207), the control signal including a first control signal used to control the lighting assembly (101, 201) and a second control signal used to control the audio playing module (104, 204). The second Bluetooth module (103, 203) is configured to receive audio data from the external device (107, 207) to transmit the audio data to the audio playing module (104, 204) for audio playing. The audio playing is controlled according to the second control signal received by the first Bluetooth module (102, 202).
