The embodiment of the utility model discloses a novel LED (light emitting diode) round light guide plate, which comprises a transparent or semitransparent plate-shaped body, wherein the end surface of one side edge of the plate-shaped body is provided with an LED lamp group, a concave-convex v-shaped groove is formed in the surface of the plate-shaped body or in an optical sheet laminated on the plate-shaped body, the concave-convex v-shaped groove is a round vein, light sources are emitted in a mode of surrounding a center point, and the brightness loss is reduced. The surface of the product is smooth, dot light sources or linear light sources are arranged at one side of the light guide plate or on the periphery of the side surface of the light guide plate, the light sources are emitted in the mode of surrounding the center point, the luminosity is concentrated to a greater degree, the brightness loss is reduced, and a series of defects generated by products in the existing market are overcome.
