 Combination of glass panels and a solar
panel allows generating and storing powerin place on the sidewalk.
 After sunset, LED light will be lit,transmitting specified colors of lightthrough the glass.
 Letters and patterns drawn on the glasswith luminescent ink will illuminate in thecolor of glass-penetrating light.
 Flashing timing and color can be flexibly
controlled to create a romantic atmospherealong the nighttime sidewalk.

The glass panel is built with consideration for strength,
skid resistance and dew concentration prevention.

pavement, except that a binder courseshould always be provided.
 An appropriate amount of water
spraying is necessary to maintain a goodheat alleviation effect.
 Water vaporization helps reduce roadsurface heating in summertime.
 The road surface looks like granite
stone paving.
 The aggregates mix is adjusted for subtle
shade and texture control.
