ELECTRIC DECORATION MAT

PURPOSE: To enable removing and treating of a surface mat for washing, when sand and soil are accumulated thereon and the like cases by a method wherein end parts of a number of photoconductors are securely inserted into a number of holes in a board while the other ends thereof are bundled to face a light source as photodetecting end and a freely detachable mat is placed on the top part of the board. CONSTITUTION: A mat having bored parts is fitted onto an upper layer of a light emitting board with photoconductors mounted on a porous board. A light source part 1 is made up of a turntable 8, a motor part 10 for rotating it and lights 9 and can project light of varied colors to cap parts 7 of the photoconductors 6 bundled. Various light is transmitted by the photoconductors 6 bundled to be emitted from end face parts 5 fixed by a sleeve through insertion holes 4 of the mat 3 through a lower layer of a porous light emitting board 11. The angles of the tips of the photoconductors and the sleeve are set 10-60 deg. and no mounting holes are previously made in the mat. In stead, the photoconductors and the sleeve are made free to remove and an upper part of the mat is pressurized to fix them.
