Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lighting systems face challenges in achieving optimal light distribution, color mixing, and aesthetic appearance due to the limitations of surface mounted LED packages and multiple color LEDs.
Innovation Solution
The proposed solution involves an LED lamp or lighting device with multiple sets of LED packages arranged in a concentric pattern, accompanied by an optical assembly comprising multiple optical elements. Each optical element is designed to control the dispersion of light emitted by corresponding sets of LED packages, allowing for precise control over light distribution and color mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple color LEDs are used in an LED lamp, then color variety and aesthetic appearance are improved, but light distribution control and color mixing become more difficult
Solution Approach 1:
The patent divides the LED lamp into multiple sets of LED packages, where each set contains LEDs of a specific color. Each set is paired with a dedicated optical element that controls the light distribution for that specific color. This segmentation allows independent optimization of each color channel while maintaining overall system performance.
Solution Approach 2:
The patent employs a nested arrangement where multiple optical elements are positioned concentrically relative to each other, with each optical element associated with a corresponding set of LED packages. The optical elements are nested in a manner that allows each to control its respective color without interfering with others, achieving compact integration of multiple optical functions.
2Ease of manufacture
If surface mounted LED packages are used, then manufacturing ease is improved, but light distribution and color mixing performance deteriorate
Solution Approach 1:
The patent applies different optical elements with specific properties tailored to each color channel. Each optical element is designed with local characteristics (such as diffusing properties, refractive indices, or surface treatments) optimized for controlling the light from its corresponding LED color set, thereby achieving high light distribution quality while maintaining standard surface-mounted LED packages.
3Manufacturing precision
If concentric arrangement of LED packages is implemented, then optical control precision is improved, but device complexity increases
Solution Approach 1:
The patent implements a nested concentric arrangement where multiple sets of LED packages and their corresponding optical elements are positioned in concentric layers. This nested structure provides precise optical control because each optical element is spatially aligned with its corresponding LED set, while the concentric geometry itself simplifies the overall structural design compared to asymmetric arrangements.
Solution Approach 2:
The concentric optical elements are designed to serve multiple functions: they control light distribution for their specific color channel, provide structural support for the nested arrangement, and contribute to the overall aesthetic appearance of the lamp. This multi-functionality reduces the need for additional separate components.
