AI Technical Summary
Conventional machine vision systems with multispectral light sources face inefficiencies due to the use of diffusers, which increase system size, reduce efficiency, and limit working distance, requiring numerous LEDs and simultaneous illumination to achieve color uniformity.
A compact illumination assembly using a plurality of multispectral light assemblies with light pipes, diffusive surfaces, and projection lenses, optimized for color mixing and uniformity, allowing direct light projection at extended distances with fewer LEDs and sequential activation of color channels.
Enables efficient, uniform illumination over a well-defined area at longer working distances with reduced hardware complexity and improved light distribution, enhancing the performance of machine vision systems in tasks like ID reading and inspection.
