Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional single-head LED spotlights are limited in their ability to achieve large area lighting and projection at a distance due to fixed mounting, which restricts their illumination coverage and leads to heat management issues affecting the lamp's lifespan during rotational adjustments.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If single-head LED spotlights are fixed to a mounting plate or sliding rail, then the structure is simple and easy to manufacture, but the illumination coverage is limited to a small area close to the spotlight head and cannot achieve large area lighting or projection at a greater distance
Solution Approach 1:
The LED spotlight head is made rotatable about a vertical centerline through the mounting opening, allowing dynamic adjustment of the beam direction. This rotational capability enables the spotlight to cover a much larger area by directing light to different locations, transforming a static fixed mounting into a dynamic adjustable system that expands illumination coverage without requiring multiple fixed spotlights
Solution Approach 2:
The invention adds rotational freedom in the vertical axis dimension, allowing the spotlight head to pivot 360 degrees around the centerline. This dimensional addition enables the beam to reach distant areas and cover large surfaces by changing the angular orientation, effectively extending the illumination range from a fixed point to a rotating coverage area
2Illumination intensity
If high-power multi-chip LED lighting design is used to increase brightness, then the illumination intensity is improved, but heat accumulation occurs that severely affects the practical life of the lamp
Solution Approach 1:
The invention converts the harmful heat generated by high-power LEDs into a manageable thermal flow by designing a heat sink structure with optimized fin geometry. The heat that would otherwise accumulate and reduce lamp lifespan is instead channeled through the finned structure to dissipate efficiently into the surrounding air, transforming a reliability-threatening factor into an controlled thermal management solution
Solution Approach 2:
The heat sink employs multiple fins with specific dimensional parameters (height, spacing, thickness) to optimize heat dissipation surface area and thermal conduction pathways. By carefully selecting and adjusting these geometric parameters, the system achieves effective heat removal from the high-power LED chips, maintaining operating temperatures within safe limits and extending lamp lifespan
3Adaptability or versatility
If conventional LED spotlight steering pivot structure is used for rotational direction adjustments, then the lamp can be positioned in different directions, but the structure cannot effectively guarantee the life of the lamp after multiple rotational adjustments
Solution Approach 1:
The mounting structure is segmented into distinct functional components: a stationary mounting plate with a vertical centerline opening, a rotatable spotlight head assembly, and a separate electrical connector system. This segmentation allows the spotlight head to rotate independently on its pivot axis without subjecting the entire mounting structure to repeated mechanical stress, isolating the rotational wear to a specific bearing or pivot point that is designed for multiple adjustments while protecting the overall system reliability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances illumination control and extends the lifespan of LED lamps by allowing adjustable illumination coverage and effective heat management, overcoming the limitations of fixed mounting and heat-related issues in conventional designs.
Implementation Method 1
As the brightness of the LED light emitting element continues to increase, and has high emission efficiency, rich color, the characteristics of small volume, the LED light emitting element as a light source of the lighting fixture is gradually widely applied
Implementation Method 2
Since the high-power multi-chip LED lighting design creates a heat problem, it cannot effectively radiate heat that would severely affect the practical life of the lamp

AI summary
A light fixture has at least one head lamp rotatably mounted to an installation board. One opening extends through the installation board into which the at least one head lamp is mounted. The at least one opening has a centerline x-x disposed perpendicular to a top surface of the installation board. One circular opening extends through an outside ring of the headlamp to mount an electrical connector having a hollow bore extending therethrough and adapted to provide a passageway for a wire to connect to a lighting assembly. The electrical connector is mounted so as to be able to pivot up to 360 degrees about a centerline through one circular opening and perpendicular to a surface of the outside ring adjacent to the circular opening irrespective of the rotational position of the headlamp on the installation board.
