Adjustable Luminaire Segmented Rotation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaires face challenges in adjustability, with many being difficult to adjust and limited in their range of motion, especially for recessed installations, and often fail to meet air-tight standards required for energy efficiency.
Innovation Solution
The design of an adjustable luminaire comprising a cylindrical upper body, an intermediate body, and a base, where the upper and intermediate bodies are rotatable to adjust the light emission angle, and features such as snap fit rims and fasteners ensure an air-tight seal, allowing for simpler installation and a wider range of adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If prior adjustable luminaire designs are used, then light emission angle adjustment is achieved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The luminaire is divided into three main cylindrical segments: upper body, intermediate body, and base. Each segment can be independently adjusted relative to the others, allowing complex light direction changes through simple sequential rotations of individual segments rather than a complex single-joint mechanism.
Solution Approach 2:
The luminaire employs dynamic adjustment capabilities where the upper body and intermediate body can rotate independently to change light emission angles. This dynamic structure allows the luminaire to adapt to different lighting requirements while maintaining a relatively simple static structure when not in use.
2Adaptability or versatility
If prior adjustable luminaire designs are used, then light emission angle adjustment is achieved, but ease of operation deteriorates due to difficulty in adjustment
Solution Approach 1:
By segmenting the adjustment mechanism into separate rotational joints at the upper-intermediate body connection and intermediate body-base connection, each joint can be adjusted independently with simple rotational motion, making operation easier compared to complex multi-axis mechanisms.
Solution Approach 2:
The cylindrical shape of the luminaire bodies with rotational joints allows for smooth, intuitive adjustment movements that are easier to operate than angular or linear adjustment mechanisms. The curved surfaces facilitate natural hand manipulation and positioning.
3Device complexity
If prior adjustable luminaire designs are used, then adjustability is achieved, but the range of motion is limited
Solution Approach 1:
The multi-segment cylindrical design with independent rotational joints at each connection point enables a wide range of motion. The upper body can rotate relative to the intermediate body, and the intermediate body can rotate relative to the base, creating multiple degrees of freedom that greatly expand the achievable light emission angles.
Solution Approach 2:
The dynamic rotational capabilities of each cylindrical segment allow the luminaire to achieve diverse light directions through coordinated movements. The system can transition between various orientations more freely than fixed-structure luminaires, expanding the effective range of motion.
4Ease of manufacture
If recessed housing is used for ceiling installation, then installation is achieved, but adjustability becomes more challenging
Solution Approach 1:
The segmented cylindrical structure with modular connection points allows the luminaire to be installed in a recessed housing while maintaining adjustment capability. The independent rotational segments can be adjusted from within the recessed installation, preserving ease of operation despite the constrained installation environment.

AI summary
An adjustable luminaire can include an upper body rotatably attached to an intermediate body. The upper body can contain a light module have an upper wall of varying height. The intermediate body can have an intermediate wall of varying height and the upper body and intermediate body can be rotatably attached so that rotating the upper body adjusts the angle at which light from the light module is emitted from the adjustable luminaire.
