Rotating Tilting Lighting Fixture Aim Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted lighting fixtures lack flexibility in directing light emission, as they typically offer only limited adjustability, which restricts their ability to effectively illuminate specific areas or provide ambient lighting without occupying valuable floor space.
Innovation Solution
A wall-mounted lighting fixture design featuring a mounting plate, canopy, and aiming assembly with a disk and tilting assembly, allowing the light emitting assembly to tilt and rotate in two degrees of freedom, enabling precise direction of light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wall-mounted lighting fixtures use fixed mounting without adjustment mechanisms, then device complexity is reduced, but adaptability and ease of operation deteriorate due to limited light direction control
Solution Approach 1:
The lighting fixture incorporates dynamic adjustment mechanisms including a tilting assembly with pivot joint that allows the light emitting assembly to tilt relative to the canopy, and a rotatable disk that enables rotation of the light emitting assembly relative to the wall. These dynamic elements transform the fixed mounting into an adjustable system, resolving the contradiction between adaptability and device complexity by providing necessary movement capabilities.
Solution Approach 2:
The invention adds rotational degrees of freedom to the lighting fixture. The light emitting assembly can tilt in one dimension via the pivot joint and rotate in another dimension via the disk mechanism. This multi-dimensional adjustment capability significantly enhances light direction control without requiring overly complex mechanisms, as each degree of freedom addresses a specific adjustment need.
2Ease of operation
If wall-mounted lighting fixtures incorporate tilting and rotation mechanisms, then ease of operation and adaptability improve, but device complexity increases
Solution Approach 1:
The aiming assembly is segmented into distinct functional components: a tilting assembly with pivot joint for vertical angle adjustment, a rotatable disk for horizontal rotation, and a light emitting assembly. This segmentation allows each component to perform a specific adjustment function independently, making the overall complex system manageable through modular design where each segment contributes to the total adaptability without requiring all components to work together simultaneously.

AI summary
A wall-mounted lighting fixture includes a mounting plate, a canopy and an aiming assembly. The canopy is secured to a mounting plate mounted to a wall. The aiming assembly includes a disk, a tilting assembly, and a light emitting assembly. The canopy defines a circular recess which the disk is positioned flush within. The tilting assembly is coupled to the disk and the light emitting assembly, and includes a pivot joint, for example a hinge, allowing the light emitting assembly to tilt relative to the disk. The disk is rotatably coupled to the canopy allowing the light emitting assembly to rotate relative to the canopy, and therefore the wall. The tilting and rotation allow emitted light from the light emitting assembly to be aimed in two degrees of freedom.
