Abstract

A method for manufacturing a glass light guide plate of high transmittance comprises steps of using a cutting machine to cut a glass flat plate, wherein the glass flat plate has a first flat surface and a second flat surface which are opposite to each other and in parallel, and a light entrance surface vertical to and connected with the first flat surface and the second flat surface; and using a thermoplastic machine for heating and extruding the light entrance surface of the glass flat plate, deforming the light entrance surface to form a light guiding part, wherein the light guiding part has a light guiding surface vertical to the first flat surface and the second flat surface and is larger than the light entrance surface in area. Therefore, when light enters the light guiding surface, light irradiating the corner of the light guiding surface can be reduced, the possibility of light reflection is lowered, light entering the glass flat plate is increased, and the light transmittance is improved.

Description

technical field [0001] The invention relates to a method for manufacturing a light guide plate, in particular to a method for manufacturing a glass light guide plate with high transmission efficiency. Background technique [0002] The role of the light guide plate is to use the principle of total reflection and scattering to guide the propagation direction of the light beam. When the light beam enters the light incident surface of the light guide plate, it will undergo total reflection and scattering inside the light guide plate. Finally, the light beam will be transmitted by the light guide plate. The light emitting surface of the light plate emits uniformly, so that the point light source or the line light source can be turned into a surface light source through the light guide plate, and can be widely used in the fields of display and lighting. [0003] Common light guide plates such as the Light guide plate with light reflection pattern in U.S. Patent No. US 7478942 disc...
