<p>A luminescent tile for use to cover the road or wall comprises a partly transparent tile plate; a plurality of solar cells arranged to receive the sun light through the transparent areas of the tile plate and generate electric power; an electric double-layer capacitor for storing electric power generated by the solar cells; a luminescent panel with its front surface facing the back of the tile plate; and a luminescence control circuit which automatically supplies the luminescent panel with power stored in the electric double-layer capacitor when ambient illuminance is below a predetermined level.</p> |
