Abstract: Disclosed is a perforated light-guiding plate, comprising a plate body (1) and a light source (3) arranged on a side of the plate body. A light-guiding hole (2) is arranged on at least one side face of the plate body. The present disclosure further discloses a method for manufacturing the perforated light-guiding plate. Various pores are fabricated on the surface of the light-guiding plate. The light distribution curve is regulated and controlled by punching holes inside the light-guiding plate and setting a direction of a punched hole (the light distribution curve of a traditional light-guiding plate is constant), thereby addressing an issue in which the light-guiding plate can only be used as an LED panel light by depending on a diffusion plate and improving practicability and artistry of the light-guiding plate.

Abstract: A light guide plate (LGP) and a lighting lamp including the LGP. The LGP has no frame and is easy to be spliced together. The LGP includes at least one sub-LGP. The sub-LGP includes at least one light source portion that is opposite to the light source, and at least one light shield installation slot that is sunken inwards and arranged beside the light source portion.
