Adjustable Lighting Assembly with Independent Axis Aiming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recessed lighting fixtures often have fixed lamps that are difficult to adjust, limiting their orientation and position, making it challenging to direct light effectively to specific target areas, especially after installation in ceilings.
Innovation Solution
An adjustable lighting assembly with a lamp holder that can be rotated about a vertical axis and adjusted independently about a horizontal axis, featuring a locking mechanism to secure the angular position, allowing easy adjustment and assembly through the open bottom of the assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed lamp holder is used in recessed lighting fixtures, then the structure is simple and stable, but the lamp cannot be adjusted to change lighting direction or focus
Solution Approach 1:
The lamp holder assembly is divided into separate functional components: a bracket portion that attaches to the fixture, a lamp holder portion that holds the lamp, and an adjustment mechanism with independent rotation and aiming capabilities. This segmentation allows each component to perform its specific function while enabling overall adjustability without excessive complexity.
Solution Approach 2:
The lamp holder is designed with dynamic adjustment capabilities, allowing it to rotate about a vertical axis and be aimed about a horizontal axis independently. This dynamic design enables the lamp position and orientation to be changed after installation, providing adaptability while maintaining a relatively simple mechanical structure through the use of rotation and aiming mechanisms.
2Adaptability or versatility
If complex adjustment mechanisms are added to allow lamp rotation and aiming, then lighting flexibility is improved, but the mechanism becomes difficult to operate and adjust
Solution Approach 1:
The adjustment mechanism is designed to be easily operable by the user without requiring complex tools or procedures. The rotation and aiming adjustments can be made directly by the user through simple manual operations, and the locking mechanism can be engaged and disengaged easily. This self-service design improves ease of operation while maintaining the desired lighting flexibility.
3Adaptability or versatility
If the lamp position is fixed during installation, then installation is simple and quick, but post-installation adjustment of light direction is limited or impossible
Solution Approach 1:
The lamp holder is pre-assembled with the adjustment mechanism and locking mechanism before installation. The bracket portion is attached to the fixture body in advance, and the lamp holder portion is prepared with rotation and aiming capabilities. This preliminary assembly allows for quick installation while maintaining post-installation adjustability, as the adjustment mechanism is already in place and ready to use after the fixture is mounted.
Solution Approach 2:
The lamp holder incorporates dynamic adjustment capabilities that allow rotation about a vertical axis and independent aiming about a horizontal axis. This dynamic design enables post-installation adjustment of light direction without requiring disassembly or complex procedures, allowing users to adjust the lighting to focus on specific target areas after the fixture is already installed in the ceiling.
4Measurement precision
If multiple adjustment mechanisms are added for independent rotation and aiming, then lighting precision is improved, but the device complexity and difficulty of assembly increase
Solution Approach 1:
The adjustment mechanism is segmented into distinct functional portions: a rotation mechanism for vertical axis rotation and an aiming mechanism for horizontal axis adjustment. Each portion is designed to perform its specific function independently, allowing for precise light positioning while keeping each individual mechanism relatively simple. The locking mechanism is also segmented to lock each degree of freedom separately.
Solution Approach 2:
The rotation and aiming mechanisms are merged into a single integrated lamp holder assembly that shares common structural elements and mounting interfaces. This merging reduces overall device complexity by eliminating redundant components and simplifying the assembly process, while still providing independent adjustment capabilities for both rotation and aiming to achieve precise light positioning.

AI summary
A luminaire and lighting assembly is provided having a ceiling pan and a light assembly supported on the ceiling pan. The light assembly is rotatable and movable in a lateral direction on the ceiling pan to provide adjustment of the light assembly with respect to the ceiling pan. The light assembly includes an aiming device which allows the lamp to be adjusted about a vertical axis and about a horizontal axis for adjustment of the lamp. The aiming assembly includes a locking assembly which fixes the position of the aiming assembly to simultaneously prevent rotation about the vertical axis and about the horizontal axis.
