  • Patent number: 7985003
    Abstract: A forming mold of a light-emitting member includes a frame, an upper mold and a lower mold, and the frame is provided with carriers, pins and supporting portions. The upper and lower molds match with each other to provide a forming space for the base of the light-emitting member. The forming space contains the carriers and a part of the supporting portions. One or more projections are disposed at the position where the brinks of the upper and lower molds contact the supporting portions. After injection molding, the burrs formed by a plastic material along the supporting portions can be concealed in the recesses that are formed corresponding to each of the projections, thereby reducing the influence of the burrs on the external size of the base.
    Type: Grant
