PURPOSE:To perform an accurate positioning in vertical direction in a resin sealing by forming a supporting projection on the inner bottom surface of a mold for an LED lamp, said projection being capable of keeping the dimension of a gap between the bottom of a support member and said inner bottom surface to a prescribed value. CONSTITUTION:LED's 6 and a lead member 3 connected thereto are supported by a support member 4, which is accommodated within a mold 1 to be positioned. The LED's 6 are arranged on every other bonding pad 31 on the lead frame 3 and wire-bonded to adjacent bonding pads through gold wires 7. The lower portion 401 of the support member 4 is recessed and a recess in the portion 401 has upward slants with a given inclination starting from the lower end portions of the four side walls of the support member 4. Strip- shaped projections 42 extending in vertical direction are formed on the side walls 40 of the support member 4. The projections 42 position the support member 4 in horizontal direction by means of a friction between the outer and inner surfaces of the projections 42 and mold 1, respectively. Other four projections 11 conduct a positioning in vertical direction to keep the dimension of a gap between the support member 4 and the mold 1 to a prescribed value. |
