Rotating Lens Panel for Adjustable LED Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lamps have fixed light distribution angles, making it difficult for users to adjust them to meet different requirements, leading to increased costs due to the need for multiple lamps.
Innovation Solution
An LED lamp design that includes a rotating shaft and adjustable lens panel, allowing users to adjust the light distribution angle by rotating the lens panel, which is fixed to a radiator with a pressing frame assembly and an adjusting assembly that includes a knob and fixing plate for manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional LED lamps use fixed light distribution angles, then the structure is simple and cost is low, but users cannot adjust to meet different requirements leading to increased purchasing costs
Solution Approach 1:
The lens panel is made rotatable relative to the radiator through a rotating shaft mechanism, transforming the fixed light distribution angle into an adjustable one. Users can rotate the lens panel to different angles to achieve various light distribution patterns, making the lamp adaptable to different lighting requirements without needing multiple fixed-angle lamps.
Solution Approach 2:
The lamp is divided into separable components including the radiator, lens panel, rotating shaft, and adjusting assembly. This segmentation allows the lens panel to be independently rotated and adjusted while maintaining connection to the radiator, enabling angle adjustment without complicating the overall structure.
2Adaptability or versatility
If multiple lamps are provided to meet different light distribution angle requirements, then various lighting needs can be satisfied, but the cost of purchasing lamps is increased
Solution Approach 1:
A single LED lamp is designed to perform multiple light distribution functions by enabling the lens panel to rotate to different angles. This multi-functional design allows one lamp to replace what would traditionally require multiple fixed-angle lamps, reducing the quantity of lamps needed while satisfying various lighting requirements.
3Ease of operation
If the lens panel is fixed to the radiator, then the structure is stable, but the light distribution angle cannot be adjusted
Solution Approach 1:
The connection between the lens panel and radiator is transformed from a fixed static connection to a dynamic rotatable connection through the rotating shaft. The lens panel can rotate along the rotating shaft to adjust the light distribution angle while maintaining stable connection during each positioned state, achieving both adjustability and stability.
Solution Approach 2:
The rotating shaft acts as an intermediary mechanism between the lens panel and radiator. It provides a controlled rotation interface that allows the lens panel to change angles while maintaining stable connection, mediating between the need for adjustment and the need for stability.
4Ease of operation
If a rotating shaft and adjusting assembly are added to enable lens panel rotation, then light distribution angle can be adjusted, but the device complexity increases
Solution Approach 1:
The adjusting assembly includes a knob that allows users to directly rotate the lens panel without requiring external tools or complex adjustment mechanisms. The simple hand-operated knob provides intuitive self-service adjustment, minimizing the complexity of the adjusting mechanism while maintaining ease of operation.
