Circular Light-Emitting Structure for Uniform Multi-Color Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-emitting structures for inspecting workpieces lack the ability to effectively emit light of different colors uniformly onto the surface, which can hinder accurate inspection due to inconsistent illumination.
Innovation Solution
A light-emitting structure comprising a base, coupling member, and cover with a light-emitting assembly that includes multiple light-emitting elements arranged in alternating colors around a central axis, allowing for even illumination of a workpiece with red, blue, and green light, and is coupled with an image detecting device for enhanced inspection capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light-emitting elements are used to provide multi-colored illumination, then the inspection capability is improved, but the light distribution uniformity deteriorates
Solution Approach 1:
The light-emitting assembly is segmented into multiple independently controllable light-emitting elements (red, blue, and green LEDs) arranged around the central axis. Each segment can be controlled separately to emit specific colors, enabling multi-colored illumination while maintaining uniform light distribution through proper arrangement and control of individual segments.
Solution Approach 2:
Different regions of the light-emitting assembly are assigned different functions by placing specific colored light-emitting elements at different positions around the central axis. This local differentiation allows each region to contribute its specific color to the overall illumination, achieving uniform multi-colored light distribution across the workpiece surface.
2Illumination intensity
If light-emitting elements are arranged around a central axis, then the light distribution uniformity is improved, but the device complexity increases
Solution Approach 1:
The light-emitting elements are arranged asymmetrically around the central axis rather than in a perfectly symmetric pattern. This asymmetric arrangement, combined with independent control of each element, enables uniform light distribution while simplifying the overall device structure and control mechanism compared to symmetric multi-element arrangements.

AI summary
A light-emitting structure includes a base, a light-emitting assembly arranged on the base, a cover configured to be covered over the light-emitting assembly, and a coupling member configured to couple the cover to the base. The light-emitting assembly emits light onto a workpiece to be inspected by an image inspection device. The light-emitting assembly is circular, and a lens of the image inspection device is rotationally coupled to the base.
