Planar Light Sources TRIZ Cases
- LED Light-Blocking Cover Structure for Directional Illumination
A raised light-blocking cover around the LED limits side leakage and prevents case contact during assembly for stable light output.
- EV Charging Station Light Animations for Clear Status Indication
Programmed light sequences help drivers quickly read charger availability, occupancy, and charging completion without adding separate indicators.
- LED Turn-Signal Jacket With Sequential Arm Arrow Indicators
Sequential LED arrows from shoulder to wrist make rider turn intent clearer in low light without adding vehicle-mounted signals.
- Reinforced Decorative Light Wiring for Tensile Strength Without Bulk
A polymer reinforcing strand with helically twisted conductors boosts tensile strength and elongation without bulky, costly light-string wiring.
- Rod Lens Light-Shielding Structure for Precise Illumination Control
A protruding light-shielding body around a rod lens absorbs side-emitted stray light to keep illuminance high and the illumination region precise.
- Wavelength-Selective Lens in LED Lighting Modules for Uniform Emission
By filtering shorter wavelengths and passing converted light, the lens-resin-phosphor stack improves extraction and surface uniformity.
- Curved Resin Lighting Structure to Eliminate Edge Dark Lines
A curved resin and light-transmitting layer shortens the side-surface light path to prevent edge dark lines and improve luminance uniformity.
- LED Reflection Layer Layout for Leakage-Resistant Lamp Reliability
A metal reflection layer with insulated, equipotential wiring reduces leakage current, metal peeling, and light failure in LED lamps.
- Phosphor Conversion Layer With Light Passages for White Light Control
Light passages in a phosphor conversion layer tune the blue/yellow ratio for consistent white light without extra light sources.
- Planar Light Source Switching Layout for Uniform Luminance
Alternating current duration by region balances LED output in a planar light source, reducing luminance unevenness across the surface.
- Shared VCSEL Optic Assembly for Range-Resolution Switching
Shared optics let flood and dot VCSEL beams switch between high-resolution short range and longer-range detection up to 6 m.
- Headlamp Sub-Matrix Optics for Homogeneous Beam Projection
Converging optics enlarge virtual images of LED sub-matrices to smooth beam gaps, improving headlamp homogeneity with fewer sources.
- Display Light Source Blinking Scheme for Wider Color Gamut
Alternating blue-red and green-red light sources widen display color gamut while preserving color purity through independent blinking control.
