Off-grid and net-zero illuminated signage: Energy harvesting via Luminescent Solar Concentrator principles

Lusoco™ is an innovative Dutch start-up that offers energy harvesting signage. The concept works via fluorescent inks on glass or a polymer, that absorb sunlight and concentrate this to the edges where small solar cells are located. The generated energy is stored in a battery and used during the night to power edge-attached LED, resulting in glowing of the image. As this happens only where the ink is printed, off-grid net-zero energy signage with high contrast images and low power consumption is achieved.
