Abstract
An optical semiconductor device for emitting a light beam includes an outer envelope that forms an indentation in which a light emitting element is positioned. The indentation is divided into a first indentation part corresponding to a lower part of the indentation, and a second indentation part corresponding to an upper part of the indentation. A projection strip between the first and second indentation parts, projects from the inner surface of the outer envelope. A conductive lead supplies an electrical power to the light emitting element.

14. A method of manufacturing an optical semiconductor device, comprising:
-
setting a conductive lead in a die;
filling the die with a resin to form an outer envelope and a projection strip, the outer envelope forming an indentation comprising a first indentation part corresponding to a lower part of the indentation and a second indentation part corresponding to an upper part of the indentation, wherein the projection strip provided between the first and second indentation parts projects from an inner surface of the indentation;
positioning a light emitting element in the first indentation part; and
filling an optical resin into the first indentation part. - View Dependent Claims (15, 16, 17, 18)
