Solution Overview
Problem
Light source devices used in disinfection and resin curing applications face challenges in achieving uniform light intensity distribution across an irradiated plane, leading to inconsistent disinfection or curing results.
Innovation Solution
A light source device comprising light-emitting diodes with viewing angles less than 50° or more than 80°, arranged at specific intervals, to enhance uniformity of light intensity by controlling the light distribution angle and optical distance to the irradiated plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light-emitting diodes with conventional viewing angles are used, then the light coverage area is sufficient, but the uniformity of light intensity in the irradiated plane deteriorates
Solution Approach 1:
The patent applies parameter changes by selecting specific viewing angle ranges (less than 50° or more than 80°) for the light-emitting diodes. This parameter optimization resolves the contradiction by finding viewing angle values that simultaneously achieve both sufficient light coverage and improved uniformity of light intensity distribution across the irradiated plane.
2Illumination intensity
If the viewing angle of light-emitting diodes is adjusted to improve uniformity, then the uniformity of light intensity improves, but the light distribution pattern becomes more restrictive
Solution Approach 1:
The patent resolves this contradiction through parameter changes by defining specific viewing angle ranges (less than 50° or more than 80°) that optimize uniformity while maintaining adequate light distribution. This parameter optimization balances the need for uniform illumination with the requirement for adaptable light coverage in disinfection and resin curing applications.
