Integrated Ceiling Lighting and Audio System with LED Arrays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing commercial ceiling and wall lighting systems do not effectively integrate lighting and audio components, leading to separate electrical and control systems, which are not suitable for large commercial applications and can pose fire hazards due to heat generation limitations.
Innovation Solution
A modular lighting and audio communication system that combines lighting and audio components in a single fixture, using LED arrays for programmable lighting and concealed audio speakers, allowing for distributed light and sound delivery with independent control and heat resistance, suitable for commercial applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional incandescent or fluorescent light sources are mounted in ceiling tiles, then illumination is provided, but heat generation creates fire hazards and limits wattage
Solution Approach 1:
The patent combines lighting and audio components into a single ceiling-mounted fixture, integrating previously separate systems. The lighting element and audio speaker are housed together in one enclosure that fits into standard ceiling grids, eliminating the need for separate mounting locations and reducing overall heat generation by consolidating power consumption.
Solution Approach 2:
The patent transitions from traditional incandescent/fluorescent sources to LED arrays, representing a fundamental change in the lighting parameter. LEDs provide equivalent or superior illumination with dramatically reduced heat generation and power consumption, directly addressing the fire hazard concern while maintaining lighting effectiveness.
2Area of stationary object
If lighting and speaker combinations are mounted together, then space is saved, but heat generation limitations restrict lighting power
Solution Approach 1:
The adoption of LED technology fundamentally changes the power parameter of the lighting system. LEDs consume significantly less power than traditional sources while providing adequate illumination, allowing the combined fixture to operate safely within the constrained thermal environment of a ceiling tile without requiring high wattage lighting.
3Reliability
If separate electrical and control systems are used for lighting and audio, then each component can be optimized, but system complexity increases and integration becomes difficult
Solution Approach 1:
The patent merges separate lighting and audio control systems into a unified control architecture. A single controller can manage both the LED lighting elements and audio speaker, simplifying installation and maintenance while maintaining the ability to independently optimize each component's performance through dedicated control channels.
4Use of energy by moving object
If LED arrays are used instead of traditional light sources, then energy efficiency improves and multiple colors are available, but programmable lighting sequences require complex control systems
Solution Approach 1:
The control system is designed with multi-functionality to handle various lighting modes and audio control from a single unified interface. The controller can manage steady-state lighting, programmable sequences, color changes, and audio-responsive lighting patterns, consolidating what would otherwise require multiple separate control systems into one versatile unit.

AI summary
A lighting and communication system with a horn enclosure for recessed ceiling panel or wall mounting, including a speaker with a horn expansion area to direct sound waves from the speaker to a horn enclosure front, at least one light enclosure located within the horn enclosure, the light enclosure defining a light cavity which is separated from said horn expansion area, with a light source inside the light cavity. The light source can be an LED array, which is capable of displaying text, colors or patterns in response to a control system signal.
