Rotating Mounting Adapter for Pole-Mounted Light Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High mast lighting and shorter pole-mounted lights often illuminate unwanted areas, such as residential neighborhoods, due to their directional limitations, causing unwanted light pollution.
Innovation Solution
A mounting adapter system for pole-mounted lights that allows for the directional orientation of luminaires, enabling them to be positioned to direct light away from undesirable areas and towards desired areas, using a combination of tenons, mounting tubes, and extension tubes to adjust the luminaire placement and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If pole-mounted lights are used to illuminate areas like roadways and parking lots, then the intended areas are well-lit, but light pollution occurs in adjacent residential neighborhoods
Solution Approach 1:
The mounting adapter incorporates a rotatable extension tube that allows the luminaire to be dynamically repositioned and reoriented. This dynamic adjustment capability enables the light direction to be changed to illuminate only the intended area while preventing light from reaching adjacent residential neighborhoods, thus solving the light pollution problem while maintaining effective illumination.
Solution Approach 2:
The mounting adapter adds a rotational dimension to the luminaire positioning system. By introducing this additional degree of freedom through the rotatable extension tube, the system can control light distribution in three-dimensional space, directing light precisely where needed and away from sensitive areas.
2Ease of operation
If standard mounting members are used with fixed luminaire positions, then installation is simple, but the ability to direct light away from sensitive areas is limited
Solution Approach 1:
The mounting adapter is divided into distinct functional segments: a mounting tube that attaches to the mounting member, an extension tube that provides rotational adjustment, and a connection interface for the luminaire. This segmentation allows each component to perform its specific function while maintaining overall simplicity and ease of installation.
Solution Approach 2:
The mounting adapter serves as an intermediary device between the fixed mounting member and the luminaire. It mediates the connection by providing the necessary rotational and positioning adjustments, thereby enabling light direction control without requiring modifications to the existing mounting member or luminaire.
3Adaptability or versatility
If luminaires are mounted directly to the mounting member, then the structure is simple, but adjustment of light direction away from sensitive areas is not possible
Solution Approach 1:
The extension tube of the mounting adapter is designed to be rotatable, providing dynamic adjustment capability. This allows the luminaire to be reoriented to different angles and directions, enabling adaptability in light distribution to direct light away from sensitive areas while maintaining a relatively simple mounting system.
Solution Approach 2:
The mounting adapter is designed as a universal component that can be attached to standard mounting members and accommodate various luminaires. It provides multiple functions including mechanical support, rotational adjustment, and positioning, thereby increasing adaptability without significantly increasing system complexity.

AI summary
An outside lighting arrangement comprises a vertical pole with upper and lower ends. A mounting member is coupled to the upper end of the pole, which mounting member has plural luminaire mounting positions located circumferentially about the pole and offset from the pole. Plural directional luminaires are provided. A mounting adaptor comprising a first portion that couples to the mounting at one of the light mounting positions, and a second portion that couples to one of the luminaires, is provided. The second portion is rotatively coupled to the first portion so as to direct light from the luminaire in the desired direction. The mounting adaptors can be used on existing selections, as well as new installations.
