A lamp capable of radiating radial pattern is disclosed, comprising a base, a transparent lampshade provided with multiple outer convex lens portions on its circumferential side and an inner recesses provided between every two adjacent outer convex lens portions, and a luminous lamp assembly located between the base and the transparent lampshade and provided with multiple luminous lamp beads. Each lamp bead is arranged corresponding to each inner recess, so that light emitted by each lamp bead respectively enters the outer convex lens portion located on both sides of each corresponding inner recess and then is refracted and converged thereby to form a radiation beam located outside the transparent lampshade and gradually shrinking from the inside to the outside, thus to radiate a brightening pattern in a circumferentially radial shape, which can greatly improve the aesthetic property and also bring people a more impressive visual impact.
