The optical dots 13 are made by printing. The first light guide network point 12 and the second light guide network point 13 constitute various luminescent patterns, including any combination of Chinese characters, letters or graphics or any combination of Chinese characters, graphics and letters. Since the engraved first light guide dots 12 are recessed into the light guide surface of the light guide plate, and the printed second light guide dots 13 are protruded from the light guide surface of the light guide plate, the light guided by the first light guide dots 12 is relatively bright forming a distinct pattern. Light guide points can be in any shape, such as circular, straight, cross and star. These light guide dots of different shapes, sizes or density distributions are combined to form various luminous patterns.

Dyeing materials or self-luminous materials can also be printed on the light-guiding dots of the light guide plate to form dots of dyed materials or self-luminous materials to construct various color luminous patterns or display various luminous patterns without light source illumination.

The light guide plate can be set in different shapes as required, such as flat plate, cylinder, polygonal cylinder and so on. Light guide grid points of different shapes, sizes or density distributions are arranged on the surface of light guide plates of various shapes.
