Solution Overview
Problem
Commercial lamps with light-emitting diodes have fixed light patterns due to a fixed distance between the second lens and the diode, making them inconvenient for use in various applications where adjustable light patterns are needed.
Innovation Solution
A luminous system with an angle-adjustable device that includes a first lens element with a light-emitting and light-incident portion, allowing for adjustable luminous angles and light patterns by changing the distance between the first and second lens elements, which can be manually or automatically controlled, including remote operation via wireless modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed distance between the second lens and the light emitting diode is used, then the structure is simple and easy to manufacture, but the light pattern cannot be adjusted for different applications
Solution Approach 1:
The patent introduces an angle-adjustable device that can change the relative position between the first lens element and the light emitting diode, transforming a static fixed-structure system into a dynamic adjustable system. This allows the luminous angle to be modified according to different application requirements, resolving the contradiction between structural simplicity and adaptability.
Solution Approach 2:
The luminous system is designed with an angle-adjustable device that enables the same system to serve multiple functions by adjusting the luminous angle. The first lens element with its specific structure (light-emitting portion, light-incident portion, and recess) can adapt to different lighting scenarios, making the system universal for various applications rather than dedicated to a single function.
2Illumination intensity
If the outer diameter of the light-incident portion decreases along a direction away from the light-emitting portion, then the light distribution and luminous angle can be optimized, but the manufacturing precision requirements increase
Solution Approach 1:
The first lens element is designed with non-uniform structure: the light-incident portion has a decreasing outer diameter away from the light-emitting portion, creating different optical properties in different regions. This local quality variation optimizes light distribution and luminous angle control, with the tapered structure guiding light rays at different angles to achieve desired illumination patterns.
