Existing LED street lamps have limitations in providing customizable light distribution patterns and stability, particularly in outdoor applications, as they often require intermediate dividers and optical lenses for varying light throws, which can be cumbersome and less efficient.
Innovation Solution
The LED light assembly features a housing with axially aligned LED light modules, heat dissipation blocks, and optional canted configurations, along with channels and protrusions for securement and enhanced heat dissipation, allowing for flexible light distribution and stability without the need for intermediate dividers or optical lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If intermediate dividers and optical lenses are used to provide varying light throws, then light distribution patterns can be achieved, but device complexity and structural cumbersome increase
Solution Approach 1:
The housing is divided into multiple segments or sections, each capable of independently adjusting the orientation of its LED light module. This segmentation allows different portions of the housing to project light in different directions, achieving varied light distribution patterns without requiring intermediate dividers or optical lenses.
Solution Approach 2:
The LED light modules are mounted on adjustable mechanisms that allow dynamic repositioning of the light sources. The modules can be tilted, rotated, or adjusted to different angles, enabling the system to adapt light distribution patterns dynamically without fixed intermediate dividers or optical lenses.
2Stability of the object's composition
If LED light modules are arranged in conventional configurations, then housing support is provided, but stability and customization for outdoor applications are limited
Solution Approach 1:
The mounting mechanism allows LED light modules to be adjusted to different orientations and angles while maintaining stable attachment to the housing. This dynamic adjustability enables customization of light distribution patterns without compromising the structural stability of the housing configuration.
Solution Approach 2:
The housing structure serves multiple functions: it provides structural support, enables stable mounting of LED modules, and allows for customizable orientation adjustment. This multi-functionality achieves both stability and adaptability in a single integrated design.
3Adaptability or versatility
If axially aligned LED light modules are used, then customizable light distribution is achieved, but heat dissipation becomes more challenging
Solution Approach 1:
The heat dissipation system is segmented into individual heat sinks for each LED light module, with each heat sink independently managing thermal loads. This segmentation allows efficient heat dissipation from each module while maintaining the axial alignment configuration for customizable light distribution.
Solution Approach 2:
Heat sinks and thermal management components serve as intermediary elements between the LED light modules and the housing. These intermediaries conduct heat away from the axially aligned modules and transfer it to the housing structure, which acts as a heat dissipation pathway.
4Ease of manufacture
If conventional mounting methods are used, then assembly is simple, but securement and stability in outdoor conditions are insufficient
Solution Approach 1:
The mounting mechanism is pre-configured with adjustment capabilities and securement features before final installation. This preliminary preparation allows for proper orientation and stable attachment to be achieved during installation, ensuring outdoor reliability without complicating the assembly process.
