Claims

[Claims for Utility Model Registration] In a lighting panel that displays characters or symbols by applying an opaque coating to the entire surface of a transparent plate excluding characters or symbols, and emitting light from a light emitting source within the transparent plate, the above-mentioned transparent A pyramid-shaped hole is formed at the character display position of the board, and the hole is transparent and has a refractive index different from that of the transparent board, and the entire surface of the board except for the display part and the characters drawn on the slope of the truncated pyramid-shaped section is The light emitted from the light emitting source located near the above letters leaks through the letters drawn on the slope of the section, is refracted through the section, and is then refracted through the section to display the display area of the section. A writing panel characterized by being able to display projected characters.
