Optical Fiber Light Brick

This is a special brick which can light up, the light source is optical fiber inside.

The brick itself doesn't have power, there is no power cable or battery in this brick.  The light comes from outside light.

When there is daylight beside, it lights up at white.

When the light source is RGB, then its lights up at RGB.

When the light source is single color, then it lights up at single color.

The size is custom available, it is ok to cut the brick into any sizes.

Regular size of the brick is 600mm x 900mm x 30mm/pcs

However it is very heavy, around 70kg/sqm.

Technical Theory:

There are many pcs of 30mm length optical fibers inside the brick, then the light can go through from one side to other side.

Then use soil mixing to make brick, or say concrete.  I think it is easy to do concrete on your side.
