Structure for guiding light into guide light plate to conduct total internal reflection


A structure for guiding light into a light guide plate to conduct total internal reflection comprises a guide light plate and a prism; the prism is integrated with the guide light plate or joined to the guide light plate with an optical adhesive layer; the horizontal surface of the prism is parallel to the upper and lower surfaces of the guide light plate; the maximum angle between the horizontal surface and the slant surface of the prism is only 20 degrees to reduce the thickness of the prism greatly to meet requirements of lightness, thinness, shortness, and smallness for the electronic product; due to a special configuration of the prism and a special arrangement between the guide light plate and the prism, the most part of the light shot to the prism by the light source with any projecting angle is guided into the guide light plate to propagate the total internal reflection such that the light has an intensity capable of being sensed.. .
