Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED-based illumination systems face challenges in adjusting light irradiation angles without expensive lenses, leading to increased production costs and limited energy efficiency due to the need for multiple lenses with different angles, which complicates installation and reduces the ability to optimize light distribution based on installation height and purpose.
Innovation Solution
A LED-based illumination assembly with an adjustable irradiation angle, featuring a base sub-assembly, movable LED-module supports, and an irradiation angle adjustment mechanism using elongate elastic plates and a worm gear system, allowing for precise adjustment of light irradiation angles without the need for multiple lenses, driven by a single power supply converter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lenses with different irradiation angles are used to adjust light distribution, then the light irradiation angle can be adapted to different installation heights and purposes, but the production cost increases due to lens molding and stocking expenses
Solution Approach 1:
The patent employs a movable LED module support that can be adjusted along the optical axis to change the irradiation angle dynamically. This eliminates the need for multiple fixed lenses with different angles, as the same LED module can be repositioned to achieve various irradiation patterns, thereby reducing production costs while maintaining adaptability.
Solution Approach 2:
The invention changes the position parameter of the LED module relative to the lens to adjust the irradiation angle. By moving the LED module along the optical axis, the effective irradiation angle changes without requiring different lenses, thus avoiding the costs associated with molding and stocking multiple lens types.
2Reliability
If a fixed lens is installed on LED modules, then the light irradiation angle is determined, but the ability to adjust light distribution based on installation conditions is lost
Solution Approach 1:
The patent introduces a dynamic adjustment mechanism that allows the LED module support to move along the optical axis. This enables the system to adapt the irradiation angle according to different installation heights and purposes, ensuring reliable light distribution optimization without being constrained by a fixed lens configuration.
3Manufacturing precision
If LED modules are used without adjustment mechanisms, then the device complexity is reduced, but the precision of light irradiation angle control is insufficient
Solution Approach 1:
The patent segments the illumination system into an adjustable LED module support and a lens assembly. This segmentation allows independent adjustment of the LED module position to achieve precise irradiation angle control, while keeping the lens structure simple and easy to manufacture.
