Semiconductor light-emitting device

A semiconductor light-emitting device comprising:

• a semiconductor light-emitting element;
• a light-transmissive resin mold part encapsulating said semiconductor light-emitting element;
• and
• converting means integrally formed with said resin mold part to convert an output light from said semiconductor light-emitting element into a linear light source to be emitted,
• wherein said resin mold part is formed of a light blocking resin having a slit in a region corresponding to a light-emitting surface of said semiconductor light-emitting element and structured to derive light of said semiconductor light-emitting element through said slit.

A semiconductor light-emitting device comprising:

• a semiconductor light-emitting element;
• a light-transmissive resin mold part encapsulating said semiconductor light-emitting element;
• and
• converting means integrally formed with said resin mold part to convert an output light from said semiconductor light-emitting element into a linear light source to be emitted,
• wherein said semiconductor light-emitting element is structured to emit light at a side surface and used as a light source of a linear light source,
• said resin mold part forming a lens by being outwardly projected in a surface where an output light from the light source of the linear light source is to be emitted toward a light-receiving part,
• said lens converting the light source of the linear light source into light sources of a multiplicity of spot light sources to emit a collimated output light from the spot light sources in multiplicity formed on said lens, and
• a measuring plate including a plurality of slits is located in the path of said collimated output light.
