Abstract： |
The invention relates to a light conductive plate and its aphototropic module. The aphototropic module comprises light source and light conductive plate with the light conductive plate composed of light entry face, light output face intersected with the entry face and bottom face opposite to the light output face. On the light face, there are at least two kinds of concave grooves that either parallel or intersected, with the parallel style having two tilt faces and the included angle of two tilt faces ranging from 60 degree to 100 degree and 100 degree to 140 degree, with the intersected grooves having two tilt faces and their included angle ranging from 30 to 70 degree or 60 to 120 degree. The aphototripic module can eliminate light post and optical hidden area with higher light luminance and evenness. |
