Pavement Lights TRIZ Cases
- Aircraft Stairway Step Lighting With Reflective Riser Illumination
Embedded LEDs and reflective riser faces light stair edges and the next step below, improving visibility on deployable aircraft stairs.
- White-Light Asphaltene Polymer Composites for Self-Illuminating Pavements
Homogeneous dispersion in a polymer matrix limits aggregation-caused quenching and enables sunlight- or UV-activated white-light pavement.
- Photoluminescent Road Marking Layers Protecting Crystal Luminosity
Drilled road holes use white paint, photoluminescent powder, and a cured transparent layer to preserve long-term luminosity.
- Ground-Level Lighting Device With Slanted Sidewalls
Slanted sidewalls and prismatic optics direct light outward at low angles, reducing roadway absorption and preventing glare for oncoming traffic.
