Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED lighting systems, especially those using reflectors or refractive lenses, are limited in their ability to adjust for varying lighting requirements, leading to inefficient light distribution and increased light pollution, as they often rely on fixed optics that cannot direct light effectively to wider areas or adjust for different mounting heights and fixture spacings.
Innovation Solution
A reflector-based illumination system with adjustable primary and auxiliary reflective surfaces, including side kick reflectors, that can be field-adjusted to optimize light directionality and intensity, allowing for more precise targeting of illuminated zones while minimizing light waste and pollution, using a retrofit kit compatible with conventional housings and power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed reflectors or refractive lenses are used in LED lighting systems, then the structure is simple and manufacturing is easy, but the ability to adjust light directionality and intensity is limited
Solution Approach 1:
The patent applies the dynamics principle by making the reflector adjustable rather than fixed. The reflector can be positioned at multiple angles and orientations to direct light in different directions, allowing the system to adapt to varying lighting requirements. This dynamic adjustment capability resolves the contradiction by enabling light directionality control without requiring multiple fixed optical components.
Solution Approach 2:
The patent segments the optical system into separate adjustable components - specifically, the reflector is separated from the LED module and can be independently positioned. This segmentation allows the reflector to be adjusted to different angles and orientations to achieve desired light distribution patterns, providing adaptability while keeping each individual component relatively simple in design.
2Productivity
If fixed optics are used to direct light, then the system is simple to manufacture, but light distribution efficiency decreases and light pollution increases
Solution Approach 1:
The adjustable reflector allows the system to be optimized for specific lighting applications after installation. By adjusting the reflector angle and orientation, the system can direct light precisely where needed, improving light distribution efficiency and reducing light pollution. This dynamic adjustment capability enables high productivity without requiring complex fixed optical systems.
Solution Approach 2:
The patent changes the parameter of reflector orientation from fixed to variable. By allowing the reflector to be positioned at different angles, the system can optimize light distribution efficiency for various mounting heights and fixture spacings, achieving high productivity while maintaining relative manufacturing simplicity.
3Illumination intensity
If multiple fixtures are installed to meet lighting requirements, then adequate illumination is achieved, but energy consumption and maintenance costs increase
Solution Approach 1:
The adjustable reflector enables each fixture to be optimized for maximum light output in the desired direction. This allows fewer fixtures to achieve the required illumination levels compared to fixed optics, thereby reducing overall energy consumption and maintenance costs while maintaining adequate illumination intensity.
Solution Approach 2:
By allowing adjustment of the reflector parameters (angle, orientation, position), each fixture can be tuned to maximize its effectiveness. This parameter optimization enables the system to achieve required illumination with fewer fixtures, reducing energy consumption and maintenance requirements.
4Adaptability or versatility
If conventional housings with fixed reflectors are used, then compatibility with existing installations is maintained, but the ability to optimize for different mounting conditions is lost
Solution Approach 1:
The adjustable reflector allows the lighting system to be optimized for specific mounting conditions such as different heights and spacings. This adaptability ensures the system operates at peak efficiency throughout its service life, extending its effective duration by preventing performance degradation from suboptimal fixed configurations.
