LED Wall Light Fixture with Diagonal Flange Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures mounted on retaining walls or under steps, decks, or railings face challenges such as difficult bulb replacement, risk of electrical shocks, water damage, and limited illumination due to downward light direction, which results in aesthetically displeasing shadows and hot spots.
Innovation Solution
A modular light fixture with a sealed housing containing a circuit board connected to LED lights via an electrical cord, featuring a diagonal flange and side attachment members for secure mounting, a skirt with stop members, and a design that projects light outwardly from the wall, reducing the reveal and enhancing illumination coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional light fixtures are mounted on retaining walls or under steps, then illumination is provided, but the reveal (overhang or protrusion) increases beyond code restrictions
Solution Approach 1:
The patent redirects light from a downward vertical direction to an outward horizontal direction by mounting the fixture on the wall surface. The light emitting diodes are arranged to project light perpendicular to the wall rather than downward, illuminating the wall face and surrounding area without requiring downward protrusion, thereby reducing the reveal while maintaining effective illumination coverage.
2Ease of repair
If bulb covers are removed to access bulbs for replacement, then bulb replacement is possible, but the process becomes difficult and presents safety risks
Solution Approach 1:
The light fixture is designed as a modular assembly with the light source, circuit board, and housing as separable components. The light emitting diodes are mounted on a circuit board that can be accessed by removing the housing, allowing for easy replacement of individual LEDs or the entire circuit board assembly without requiring complex disassembly or posing safety risks.
3Ease of manufacture
If light fixtures direct light downwards, then installation is simple, but shadows and hot spots are created that are aesthetically displeasing
Solution Approach 1:
The patent employs multiple light emitting diodes positioned at different locations on the circuit board to create varied light emission points. This arrangement produces a more uniform light distribution across the illuminated surface, eliminating concentrated hot spots and reducing shadow formation while maintaining aesthetic quality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular design allows for safer and easier bulb replacement, prevents water damage, and provides a wider illumination radius with reduced energy consumption compared to traditional fixtures, while minimizing the risk of electrical shocks and improving aesthetic appeal.
Implementation Method 1
a circuit board with electrical contacts configured to provide electrical power to a plurality of light emitting diode (LED) lights connected thereto
