The present invention provides a diffusion cover for an LED lamp apparatus, which is coupled to a body to receive an LED module therein. The diffusion cover is made of a colorless transparent polycarbonate material and has cover rows, the number of which corresponds to the number of LED module rows, each of which has a lower surface, an inner surface formed by bending one side of the lower surface and an outer surface formed by bending an opposite side of the lower surface, wherein the lower, inner and outer surfaces are integrally formed. The cover rows are integrally connected to each other through each connection surface. Each of the cover rows has a curved surface having a semicircular shape. A side surface of one of the inner and outer surfaces is inclined or all of the inner and outer surfaces of the cover row are inclined. One LED module row is received in one cover row so that one diffusion cover can provide effect similar to that provided by several diffusion covers. The cover rows are provided in parallel, radial or concentric shape, so that the diffusion of light emitted from LEDs may be enhanced. Since the diffusion cover is made of a colorless transparent polycarbonate material, the transmittance of light emitted from the LEDs may be increased and the energy loss may be reduced. |
