Edge-Lit Light Fixture With Secondary Speaker Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures face challenges in packaging multiple components that provide different functions, such as LEDs and speakers, due to limited space, which can compromise light quality and aesthetics, as well as sound quality due to interference with light radiation.
Innovation Solution
An edge-lit light fixture design that incorporates a secondary element like a speaker within a housing, utilizing a waveguide and edge-lit LED configuration to optimize packaging space and maintain sound quality while meeting lumen requirements, with a heat sink and driver boards for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple components (LEDs and speakers) are packaged into a single light fixture, then the device provides multiple functions (lighting and sound), but the limited space compromises light quality, aesthetics, and sound quality
Solution Approach 1:
The patent positions the speaker in the plane of the waveguide rather than stacking components vertically, utilizing the lateral space within the housing. This dimensional arrangement allows both the LED light engine and speaker to coexist without interfering with light radiation patterns or sound quality, resolving the space constraint contradiction.
2Adaptability or versatility
If multiple components are packaged into a single light fixture, then the device provides multiple functions, but the additional components interfere with the light fixture's ability to radiate light effectively
Solution Approach 1:
The patent designates specific zones within the housing: the speaker is positioned in one plane while the LED light engine occupies another, with each component localized to minimize interference. The waveguide structure is specifically designed to channel light from the LEDs while the speaker operates in its designated acoustic zone, allowing both functions to perform optimally without compromising light radiation effectiveness.
3Adaptability or versatility
If the light fixture includes a speaker to provide sound function, then the device offers additional service, but the sound quality or level is compromised to fulfill the light fixture's lumen requirements
Solution Approach 1:
By positioning the speaker in the plane of the waveguide rather than stacking it above or below the LEDs, the patent creates separate functional zones that do not compete for space. This lateral arrangement allows the speaker to achieve adequate sound quality and volume while the LED light engine maintains its lumen output requirements, as neither component needs to be sacrificed for the other's performance.

AI summary
A light fixture is disclosed, and includes a light emitting diode (LED) engine including plurality of LEDs that transmit visible light. The light fixture also includes a waveguide, where the LEDs of the LED engine surround the waveguide and transmit the visible light in a direction towards the waveguide. The light fixture also includes a second element that provides a secondary service. The light fixture also includes a housing that defines a cavity, where the LED engine and waveguide are positioned within the cavity proximate the front of the light fixture, and the a secondary element is positioned within the cavity toward the rear of the light fixture.
