摘要： A light guide plate includes a body having a bottom surface and a light output surface opposite to the bottom surface. A reflector is located on the light output surface opposite to the center of the bottom surface. The reflector is a cavity concaved from the light output surface to the inside of the body. A plurality of scattering dots are located on the bottom surface. The scattering dots are arranged in the form of a plurality of concentric circles around the center of the bottom surface. The number of the scattering dots is defined based on a radius of the circle they reside on, and the radius of the circle is greater than or substantially equal to 4 millimeter.

摘要： The present invention discloses a device for processing columnar curved tempered glass. The device mainly comprises a glass heating furnace, a glass bending mechanism and a glass tempering mechanism connected sequentially, wherein the arrangement of each supporting roller in the rollers supporting the high temperature flat glass is changed from planar arrangement in space into curved arrangement corresponding to the shape of the glass to be formed, so that the glass bending mechanism enables the glass to suffer bending deformation. Transferring rollers for outputting the formed curved glass in the axial direction of the supporting roller are arranged at the clearance of the rollers of the bending mechanism. In the present invention, bending shaping and tempering of the high temperature flat glass are completed by two stations to break the normal procedure that bending shaping tempering are carried out by one bending appliance intensively, thereby providing a novel technological approach for processing columnar curved tempered glass.
