The invention discloses a novel luminous character and a manufacturing method thereof. The novel luminous character comprises two mutually symmetrical shells, wherein the two shells are attached together through waterproof sealing glue, so that the sealing property and the waterproof capability of the novel luminous character are improved; a groove is formed in each shell; an LED lamp strip is arranged in the middle of the two sides of each groove separately, and the two LED lamp strips are symmetrical to each other; lamp beads on the two LED lamp strips are both facing the inner side of the grooves; the grooves between the two LED lamp strips are filled with a light homogenizing agent layer; the two LED lamp strips are relatively light-emitting, and then the light is scattered through thelight homogenizing agent layer, so that it is ensured that shading is avoided, and uniform light emission can be achieved; the width of the grooves is 6 to 50 mm, the depth of the grooves is 3 to 30mm, the width of the LED lamp strips is 2 to 24 mm, and the distance between the lamp beads on the LED lamp strips is 7 to 12 mm; and the shadow of the illumination is further eliminated through control of the size, the structure of the original luminous character is changed, the structure is simplified, and the production process difficulty is reduced.
