Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optics units for lamps often result in uneven illumination and glare, making them ineffective for large areas and potentially distracting for people nearby.
Innovation Solution
The design incorporates multiple rows of adjacent optical lenses within a rectangular, one-piece transparent plastic body, with a metal support frame and optional intermediate pieces, allowing for uniform and glare-free illumination by directing light emissions effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional reflectors are used to illuminate larger areas, then the illumination coverage is improved, but the illumination uniformity deteriorates and glare is generated
Solution Approach 1:
The optical unit is divided into multiple rows of optical lenses (at least two rows) that are adjacent to each other. Each lens individually directs light from its associated illuminant, creating multiple light paths that combine to provide uniform illumination across a large area without the glare problems of traditional reflectors.
Solution Approach 2:
The patent transitions from traditional two-dimensional reflector surfaces to a three-dimensional array of discrete optical lenses arranged in multiple rows. This dimensional change allows for precise control of light distribution in both horizontal and vertical directions, achieving uniform illumination across larger areas while eliminating glare.
2Area of stationary object
If traditional reflectors are used to illuminate larger areas, then the illumination coverage area is improved, but glare is generated for people in the vicinity
Solution Approach 1:
By segmenting the illumination system into multiple discrete optical lenses instead of using a continuous reflector surface, the patent achieves diffuse light distribution that covers large areas without creating concentrated glare spots. Each lens individually controls its light output, preventing the formation of harsh glare.
3Illumination intensity
If multiple optical lenses are used to achieve uniform illumination, then the illumination uniformity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent merges multiple optical lenses and their supporting structures into a single integral optical unit. This unified design allows the lenses to be positioned relative to each other with fixed tolerances determined during manufacturing of the entire unit, rather than requiring precise field assembly of individual components, thereby reducing overall positioning tolerance requirements.
