Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor luminaires for parking lots and decks struggle to efficiently direct light while minimizing glare and preventing light from shining into adjacent areas, such as houses or apartments, while also needing to be sturdy, aesthetically pleasing, and adaptable for various mounting locations.
Innovation Solution
A luminaire design featuring a frame with optical waveguides positioned at different angles and a light shield or coating to direct light outward in multiple directions, with the option to obstruct light emission in specific directions using a mask or panel, ensuring uniform illumination and reduced glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If optical waveguides are used to direct light outward in multiple directions, then illumination coverage is improved, but glare control becomes difficult
Solution Approach 1:
The luminaire is divided into multiple optical waveguides (typically four) positioned at different angles around the frame, each waveguide segment directing light in a specific direction. This segmentation allows the illumination coverage to be expanded across multiple areas while each individual waveguide can be controlled to minimize glare in its specific direction.
2Object-generated harmful factors
If light shield is added to block light in specific directions, then glare control is improved, but device complexity increases
Solution Approach 1:
The light shield is integrated with the frame structure of the luminaire, combining the shielding function with the existing structural elements. This merging approach provides effective glare control by blocking light in unwanted directions while avoiding the need for separate, complex shielding mechanisms.
3Stability of the object's composition
If multiple optical waveguides are positioned at different angles, then light distribution uniformity is improved, but manufacturing precision requirements increase
Solution Approach 1:
The optical waveguides are positioned at different angles relative to the frame (typically spaced at approximately 90-degree intervals), creating an asymmetric arrangement that distributes light uniformly in multiple directions. This asymmetric positioning optimizes illumination coverage while the design accommodates reasonable manufacturing tolerances.
4Reliability
If luminaire is designed to be sturdy for outdoor conditions, then reliability is improved, but weight increases
Solution Approach 1:
The frame and optical waveguides are constructed from materials that provide adequate strength and weather resistance for outdoor conditions while controlling weight. Material selection and structural parameter optimization allow the luminaire to withstand wind and weathering forces while remaining light enough for ease of installation.
