Concentric Ring Lamp Adjustment Mechanism for Precise Light Source Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures lack precise and efficient mechanisms for independent adjustment of a light source relative to a reflector, limiting the ability to accurately position the light source for optimal performance.
Innovation Solution
The light fixture employs a system of three concentric rings (inner, middle, and outer) with independent adjustment screws, allowing for precise tilting and longitudinal movement of the light source in three directions, enabling precise alignment and repositioning of the light source within the reflector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single adjustment mechanism is used to position the light source, then the device complexity is reduced, but the measurement precision and manufacturing precision of light source positioning deteriorates
Solution Approach 1:
The adjustment mechanism is divided into three independent concentric rings (first inner ring, second middle ring, third outer ring), each responsible for adjustment in a specific direction (X, Y, Z respectively). This segmentation allows precise control of light source positioning in each dimension independently, achieving high positioning precision while keeping each individual adjustment mechanism simple.
2Device complexity
If the light source is fixed in position, then the device complexity is reduced, but the adaptability to adjust light source position for optimal performance deteriorates
Solution Approach 1:
The light source positioning system transitions from a fixed configuration to a dynamic adjustable system. The three concentric rings can be independently adjusted in their respective directions (X, Y, Z), allowing the light source to be repositioned flexibly to achieve optimal performance for different applications while maintaining a relatively simple overall structure.
3Measurement precision
If independent adjustment in three directions is implemented, then the measurement precision of light source positioning is improved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism is divided into three independent concentric rings (first inner ring, second middle ring, third outer ring), each responsible for adjustment in a specific direction (X, Y, Z respectively). This segmentation allows precise control of light source positioning in each dimension independently, achieving high positioning precision while keeping each individual adjustment mechanism simple.
Solution Approach 2:
The three adjustment rings are arranged concentrically with the first inner ring inside the second middle ring, which is inside the third outer ring. This nested arrangement allows compact integration of multiple adjustment degrees of freedom into a space-efficient structure, achieving three-dimensional positioning capability without proportionally increasing the overall device footprint or complexity.

AI summary
The present invention relates lamp adjustment in a light fixture, where a lamp socket from the backside of a reflector is adjustable by screwing means in one or more directions. It is an object of this invention to perform effective independent adjustment of a light source in relation to a reflector. The lamp socket is adjustable in three directions by independent adjusting means, where a first adjustment in a first X direction is performed by tilting fist inner ring by first screwing means, where a second adjustment in a second Y direction is performed by tilting a second middle ring by second screwing means, where a third adjustment is performed by a linear translation of a third outer ring by third screwing means in relation to a surrounding frame.
