Concentric Louver Sharpener for Soft Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sharpeners for lighting fixtures are not suitable for producing soft light, as they are primarily designed to create sharp-edged light.
Innovation Solution
A sharpener with a cylindrical inner and outer louver portion configuration, where the back ends are closer to the light-emitting surface and the front ends are farther away, allowing for controlled light emission angles and integration of a condenser lens and annular mounting ring, to produce soft and uniform light by adjusting the emission angles and preventing direct light inclusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sharpener is configured with louver portions to produce sharp-edged light, then light control precision is improved, but the ability to produce soft light deteriorates
Solution Approach 1:
The sharpener is divided into multiple louver portions (first louver portion and second louver portion) with different orientations and functions. The first louver portion controls light in one direction while the second louver portion controls light in another direction, allowing the system to achieve both sharp-edged light control and soft light production through segmented functional zones
Solution Approach 2:
Different regions of the sharpener are assigned different functional qualities: the first louver portion is optimized for sharp light control with specific angular restrictions, while the second louver portion is configured to allow broader light diffusion. This local differentiation enables the same device to produce both sharp-edged and soft light outputs
2Measurement precision
If the front end of the inner louver portion is positioned farther from the light-emitting surface, then sharp light control is improved, but soft light production deteriorates
Solution Approach 1:
The invention transitions from a single-dimensional louver configuration to a multi-dimensional arrangement where louver portions are positioned at different radial distances and angular orientations from the light-emitting surface. This spatial dimensionality allows simultaneous achievement of sharp light control (through distant louver portions) and soft light production (through closer louver portions)
3Speed
If the louver portions are configured to restrict light emission angles, then light directionality is improved, but light distribution uniformity deteriorates
Solution Approach 1:
The louver portions are arranged asymmetrically with different angular restrictions and orientations relative to the light-emitting surface. This asymmetric configuration allows the system to maintain overall light distribution uniformity while achieving directional control through strategically positioned asymmetric elements that compensate for each other's restrictions
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 configuration enables increased light emission and controlled emission angles, resulting in a soft and uniformly irradiated region with the light emitted from the sharpener, achieving a soft light output.
Implementation Method 1
a condenser lens disposed in the vicinity of the back end of the inner louver portion

AI summary
A sharpener comprises a cylindrical inner louver portion and a cylindrical outer louver portion each disposed concentrically about an axis that extends forward from a center of a light-emitting surface. Respective back ends of the inner louver portion and the outer louver portion are disposed nearer to the light-emitting surface, and respective front ends and are disposed farther from the light-emitting surface, and the front end of the inner louver portion is disposed nearer to the light-emitting surface than the front end of the outer louver portion is.
