Smooth surface, the side opposite with the incidence surface, the reflective surface are provided with reflecting layer, and the reflecting layer includes that several specifications are identical
Projection piece, the projection piece is uniformly protrusively provided in the lateral surface of the reflective surface, when the source light for passing through the incidence surface
When line enters the reflecting surface, several projection pieces carry out diffusing reflection to the source light and obtain soft uniform environment light,
The environment light is transmitted from the light-emitting surface.
Preferably, the reflective surface is plane, cambered surface or irregular face.
Preferably, the shape of the light-emitting surface is identical with the shape of the reflective surface.
Preferably, the projection piece is graininess, ring-type, multilateral shape or irregular shape.
The positive effect of the utility model is:
The utility model overcomes the light guide plate problem bad to light source diffusion and light guide effect, and light guide effect is good, can
According to light source concrete condition using the site of rule or irregular shape, keep the light transmitted more uniform, because can be to source light
Line carries out sufficiently leaded light, energy saving；The light guide plate that Mold Making the utility model can be used, the technique for simplifying production are raw
It produces high-efficient.
