LED Light Arrangement With Replaceable Second Lens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LED light emission arrangements require replacement of the entire optical element to change the beam angle, leading to high costs due to the need for new molds and production of separate tools for each alternative embodiment.
Innovation Solution
Incorporating a second lens after the first lens in the light emission direction, which can adjust the emission angle by either reducing or increasing it, allowing for changes in the beam angle without replacing the optical element, using triangular or V-shaped designs to deflect light accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the beam angle is changed by replacing the entire optical element, then the beam angle can be adjusted to suit different lighting needs, but the production and maintenance costs increase due to the need for new molds and separate tools for each alternative embodiment
Solution Approach 1:
The optical element is divided into a first lens (integrated with the LED module) and a second lens (separate and replaceable). This segmentation allows the second lens to be changed independently to adjust the beam angle without replacing the entire optical element or requiring new molds for different beam angles, thereby reducing production costs while maintaining adaptability.
Solution Approach 2:
The system transitions from a static optical element where beam angle is fixed by the lens design to a dynamic system where the beam angle can be adjusted by replacing the second lens. This enables the lighting arrangement to adapt to different lighting needs without incurring the high costs of manufacturing multiple complete optical elements with different beam angles.
2Adaptability or versatility
If the beam angle is changed by replacing the entire optical element, then the desired emission characteristic can be achieved, but the complexity of the system increases due to the need for multiple separate tools and molds for each alternative embodiment
Solution Approach 1:
By segmenting the optical element into a fixed first lens and a replaceable second lens, the system reduces complexity. Instead of requiring multiple complete optical elements with different beam angles (each requiring its own mold and tooling), the system uses a single first lens with multiple interchangeable second lenses, simplifying the overall system architecture.
Solution Approach 2:
The first lens is designed to be universal and compatible with multiple different second lenses that provide different beam angles. This multi-functionality allows a single first lens to serve multiple lighting applications by simply changing the second lens, rather than requiring separate specialized optical elements for each application.
3Adaptability or versatility
If a second lens is added downstream of the first lens to adjust the beam angle, then the beam angle can be flexibly changed without replacing the optical element, but the device complexity increases due to the additional lens component
Solution Approach 1:
The optical system is segmented into two functional parts: the first lens that provides the base optical function and the second lens that provides beam angle adjustment. This segmentation allows the beam angle adjustment function to be added without redesigning the entire optical element, and the replaceable second lens minimizes the permanent increase in device complexity.
Solution Approach 2:
The second lens acts as an intermediary component between the LED light source and the final light output. By placing this adjustable element downstream of the first lens, it mediates the beam angle adjustment function without requiring fundamental changes to the LED module or first lens design, thus adding minimal complexity while maximizing flexibility.
