Abstract:
A semiconductor light-emitting device comprising:at least two parallel leads having adjacent distal ends; a semiconductor light-emitting chip mounted on the distal end of one of said leads; a bonding wire for electrically connecting the semiconductor light-emitting chip and the distal end of another of the at least two leads; and a light-transmitting resin, for sealing said semiconductor light-emitting chip, said bonding wire, and the distal ends of said leads, the light-transmitting resin having a side surface defined in lateral cross section by an ellipse having a long axis and a short axis, the long axis being perpendicular to a lateral straight line as extending through said at least two parallel leads, and a convex external end surface for transmitting light from the semiconductor light-emitting chip to the exterior of the light-transmitting resin.
