Adjustable Light Distribution via Lens Matrix Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems lack versatility in directing light efficiently, as they often require different lenses for varying light distributions, and existing solutions do not effectively utilize the emitted light from fixtures positioned at the periphery of areas like parking lots.
Innovation Solution
A lens matrix system comprising a plurality of lenses with varying optical properties that can be positioned and translated relative to a light source, such as LEDs, to alter the light distribution by changing the orientation of LEDs within the lenses or moving them to different lenses with distinct optical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual removable lenses are used to direct light in specific directions, then lighting versatility is improved, but device complexity increases due to needing multiple different lenses for different distributions
Solution Approach 1:
A single lens is designed to perform multiple functions by dynamically changing its optical properties. The lens can transform between different light distribution patterns (e.g., spot, flood, asymmetric) through controlled deformation, eliminating the need for multiple separate lenses while maintaining full lighting versatility
Solution Approach 2:
The lens incorporates dynamic elements that allow real-time adjustment of its optical characteristics. By changing the lens shape or refractive index through actuators, temperature control, or electro-optic effects, a single lens can adapt to provide various lighting distributions as needed
2Illumination intensity
If light is directed symmetrically downwardly from a central fixture, then uniform illumination is achieved, but light efficiency deteriorates when the fixture is positioned at the periphery
Solution Approach 1:
The lens is designed with asymmetric optical properties that can be activated based on fixture position. When positioned at a periphery location, the lens deforms or reconfigures to create an asymmetric light distribution pattern that directs all light toward the target area, eliminating waste while maintaining adequate illumination uniformity
Solution Approach 2:
The lens dynamically changes its optical parameters (shape, refractive index, thickness) based on the detected position and lighting requirements. This allows the same lens to provide symmetric distribution when centrally positioned and asymmetric distribution when peripherally positioned, optimizing both uniformity and efficiency for each scenario
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
Enables flexible and efficient light distribution by allowing multiple light patterns to be created without the need for multiple lenses, maximizing the use of emitted light and accommodating different lighting requirements with minimal adjustments.
Implementation Method 1
the light emitted from the LEDs is directed into the lenses, which in turn emit the light in a particular distribution
Data Source
AI summary
A lighting assembly having a plurality of light sources and a lens matrix having a plurality of lenses. The lens matrix may be positioned relative to the light sources so that each light source resides in a first orientation within one of the lenses and emits a light distribution. Relative translation between the light sources and the lens matrix alters the orientation of the light sources within the lenses, creating a different light distribution. A light source's orientation may change within the same lens, or the light source may translate to a different lens to alter the distribution of its emitted light.
