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.
