Light Guides With Fluorescent Dopants TRIZ Cases
- Multicore Fiber Amplifier Combiner With Pump Spot Size Conversion
A core size conversion unit matches pump spot size to the amplifier cladding, cutting combiner loss and improving multicore fiber amplification efficiency.
- Beveled Fluorescent Crystal Geometry for Trapped Light Extraction
Beveled crystal vertices or edges create escape paths for trapped luminescent rays, boosting exit beam luminance and power.
- Waveguide Pupil Expander for Wider HUD Eye-Box and Field of View
Internal-reflection waveguides replicate the exit pupil in two dimensions, enlarging HUD eye-box and field of view in a compact layout.
- FDM Printed Material Doping for Local Optical Property Switching
Temperature-triggered dopants let one FDM material create reflective, transparent, or colored regions without multi-material printing.
- Transparent Luminescent Solar Concentrator With Low-Index Film
A lower-refractive-index film helps retain re-emitted photons in a transparent waveguide while supporting arbitrary-surface integration.
- Light Conversion Element with Remote Down-Conversion Cavities
Segmented light guides house down-conversion material in remote cavities, reducing thermal degradation while maintaining high light conversion efficiency.
- Backlight Unit Quantum Dot Phosphor Heat Management
A backlight unit positions quantum dot phosphor remotely from the light source to minimize heat-induced degradation.
- LED Light Conversion Structure for Thermal Decoupling
Conversion structure decouples thermal and optical paths, enabling high lumen flux from compact LED volumes without heat-induced efficiency loss.
- Photoluminescent Layer Submicron Structure Directional Light
Submicron structures on the photoluminescent layer direct light output, eliminating bulky external optical elements.
