The present invention relates to a diffusion cover for a light emitting diode lamp apparatus coupled with a body to receive an LED module therein. The diffusion cover includes a colorless transparent polycarbonate material. The diffusion cover is configured at an outer bottom surface or an inner bottom surface by a repeated pattern with a predetermined interval, integrally protrudes, and include a pattern protrusion of a transparent polycarbonate material. The diffusion cover is repeated at an inner bottom surface at a predetermined interval and integrally protrudes, and includes a semi-circular protrusion, a triangular pole protrusion or a rectangular pole protrusion. The diffusion cover is integrated with a lateral side of a pattern protrusion with a predetermined width. The diffusion cover further includes a triangular protrusion of colorless transparent polycarbonate material having a triangular section. The diffusion cover is repeated at an outer lateral side or an inner lateral side and integrally protrudes, and includes a semi-circumference protrusion of colorless transparent polycarbonate material. Light emitted from the LED by the pattern protrusion and the semi-circular protrusion is variously refracted so that light is diffused or scattered. The diffusion cover includes a colorless transparent polycarbonate material to represent transmission rate of light emitted from the LED, thereby reducing energy consumption. Diffusion of light emitted from the LED is increased due to the triangular protrusion. The light emitted from the LED is irradiated to a lateral side of the diffusion cover due to the semi-circumference protrusion, a triangular circumference protrusion, and a rectangular circumference protrusion. |
