Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optoelectronic components, such as light emitting diode (LED) components, face challenges in effectively illuminating spatial or areal regions at angles other than 90 degrees due to limitations in beam shaping and deflection, leading to inefficient radiation distribution and potential corruption of beam profiles.
Innovation Solution
The integration of a deflection element, such as a prism structure, and an optical lens with a non-radially symmetrical configuration, where the optical axis is tilted relative to the radiation emission face, allows for effective beam deflection and focusing, enabling illumination of regions at angles other than 90 degrees with minimal corruption of the beam profile, and potentially simplifying construction and manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional optical lenses with optical axis perpendicular to the radiation emission face are used, then the beam profile remains symmetrical, but the spatial region at oblique angles cannot be effectively illuminated
Solution Approach 1:
The patent applies asymmetry by tilting the optical axis of the lens relative to the radiation emission face at a specific angle. This asymmetric configuration enables the optical system to effectively illuminate spatial regions at oblique angles while maintaining beam focusing capability, resolving the contradiction between illumination effectiveness and system complexity.
2Adaptability or versatility
If beam deflection is implemented to illuminate oblique regions, then spatial coverage is improved, but beam profile corruption occurs
Solution Approach 1:
The patent employs asymmetric tilting of both the deflection element and the optical lens, with their optical axes tilted by the same angle relative to the radiation emission face. This coordinated asymmetric configuration enables effective beam deflection to illuminate oblique regions while preserving beam profile quality, as the symmetrical arrangement of tilted elements compensates for potential profile corruption.
Solution Approach 2:
The patent combines the deflection element and the optical lens into an integrated optical system where both elements are tilted by the same angle. This merging of functions allows the system to simultaneously achieve beam deflection for spatial coverage and beam focusing for profile quality, resolving the contradiction between adaptability and manufacturing precision.
3Adaptability or versatility
If multiple separate optical elements are used for beam shaping and deflection, then functional requirements are met, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges the beam deflection function and beam shaping function into a coordinated optical system where the deflection element and optical lens work together as an integrated unit. Both elements are tilted by the same angle and positioned to function collectively, which simplifies manufacturing and handling while maintaining full beam control capability for illuminating oblique regions.
