Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED light fixtures with fixed lenses struggle to achieve complex and flexible light distribution patterns, as they are not adaptable to individual LED orientations, limiting their ability to optimize light output and coverage.
Innovation Solution
The development of orientable lenses that can be individually adjusted around each LED, comprising a base with mating surfaces for attachment, a refracting lens, primary reflector, reflecting portions, and a reflective prism, allowing for customizable light redirection and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed lenses are used in LED fixtures, then the lens structure is simple and easy to manufacture, but the light distribution pattern is limited and inflexible
Solution Approach 1:
The lens is divided into multiple independent segments or surfaces, each capable of redirecting light in different directions. This segmentation allows the lens to create complex light distribution patterns while maintaining manufacturing feasibility through modular design approaches.
Solution Approach 2:
The lens incorporates variable optical properties across different regions, with each zone designed to dynamically redirect light based on its specific geometric configuration. This allows the fixed lens structure to achieve adaptive-like light distribution flexibility without requiring moving parts.
2Productivity
If fixed lenses are used, then manufacturing and installation are straightforward, but the ability to optimize light output for individual LED orientations is limited
Solution Approach 1:
Different regions of the lens are designed with distinct optical properties and redirection angles tailored to specific LED orientations. This local customization optimizes light output efficiency for each LED position while maintaining a unified lens structure that simplifies installation compared to multiple individual lenses.
Solution Approach 2:
The lens design incorporates multiple functional zones within a single component that can accommodate various LED orientations and requirements. This multi-functionality allows one lens to replace what would traditionally require multiple specialized lenses, simplifying installation while optimizing light output for different LED configurations.
3Illumination intensity
If conventional lenses are used, then the device structure is simple, but complex and flexible light distribution patterns cannot be achieved
Solution Approach 1:
The lens utilizes three-dimensional geometric configurations and multi-surface designs to control light distribution in multiple spatial dimensions simultaneously. This dimensional approach enables complex light patterns to be achieved through geometric design rather than requiring complex mechanical or electronic control systems.

AI summary
A mounting surface for mounting a plurality of LEDs has a plurality of orientable lenses each individually affixed about a single LED. Each orientable lens has a primary reflector and a refracting lens that direct light emitted from a single LED to a reflective surface of the orientable lens that reflects the light off a primary LED light output axis.
