发明名称 LIGHT EMITTING DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a light emitting device having high reliability and longevity by suppressing peeling of sealing resin and an opening inner edge in a concave of a housing. <P>SOLUTION: A light emitting device comprises: a light emitting element having a pair of electrodes; a housing having a concave accommodating the light emitting element; a first lead electrode and a second lead electrode which are exposed at the bottom of the concave; a pair of electrodes of the light emitting element; a conductive member by which the first lead electrode and the second lead electrode are electrically connected to each other; translucent sealing material filled in the concave; and a granular additive contained in the sealing material. An inner wall surface of the concave comprises a shading unit shading light irradiated from the light emitting element to the opening inner edge of the concave, and an additive amount of the granular additive in the sealing material is adjusted to an amount for raising dispersion of the light in a first region below the shading unit, and adjusted to an amount for suppressing the dispersion of the light in a second region above the shading unit. <P>COPYRIGHT: (C)2012,JPO&INPIT
