Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual LED light fixtures lack user-friendly configurability and installation ease, and do not effectively utilize a common power source and dimming circuit to power both lower and upper LED light sources independently or simultaneously, with limited control options and a fixed design that does not allow for adjustable light intensity and color temperature.
Innovation Solution
A dual LED light fixture with a user-configurable upper light housing, utilizing a common power source and dimming circuit, independent drive current circuits, and remote or local control options, allowing for adjustable light intensity and color temperature, and a design that creates a floating impression by emitting light from behind the lower housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a dual LED light fixture is designed with fixed construction, then manufacturing is simplified, but user configurability and adaptability are reduced
Solution Approach 1:
The upper light housing is divided into separate modular components including the upper housing, diffuser, and trim pieces that can be independently assembled or removed. This segmentation allows users to configure different arrangements while maintaining manufacturing simplicity through standardized parts.
Solution Approach 2:
The fixture incorporates adjustable and reconfigurable elements in the upper light housing that allow users to modify the configuration after installation. This dynamic capability enables adaptability without requiring complex manufacturing processes, as the base structure remains simple and standardized.
2Ease of operation
If separate power sources and control circuits are used for upper and lower LED light sources, then independent control is achieved, but device complexity increases
Solution Approach 1:
The patent combines the power supply and control functions into a single integrated circuit board that serves both the upper and lower LED light sources. This merging reduces device complexity by eliminating separate power supplies and control circuits, while still enabling independent operation through software-controlled channels.
Solution Approach 2:
The single power supply and control circuit is designed to universally support both upper and lower LED light sources through multiple output channels. This multi-functional design allows the same hardware to provide independent control to different light sources without requiring duplicate components.
3Illumination intensity
If the upper LED light source is positioned close to the outer circumferential area, then side light emission is maximized, but the floating visual effect is reduced
Solution Approach 1:
The patent positions the upper LED light source in the hub region rather than at the outer circumferential edge, utilizing the vertical and radial dimensions strategically. This positioning allows light to emit upward and outward at angles that create the floating effect, while still providing adequate side illumination through the diffuser and trim design.
Solution Approach 2:
The diffuser and trim pieces act as intermediaries that redirect and distribute light from the hub-positioned LED source. These intermediary elements shape the light path to achieve both side light emission and the floating visual effect, decoupling the physical position of the LED from its functional light distribution.

Function Achieved in This Case
Enables easy installation, independent control of both LED light sources, adjustable light intensity and color temperature, and a visually appealing floating effect, enhancing user experience and functionality.
Implementation Method 1
A lower LED light source may be mounted in the lower LED light source housing to generate front light, the lower LED light source generating front light as downlight. An upper LED light source may generate rear light illumination
