摘要:
A light emitting device includes a substrate, a light source, a cover member, a light transmissive member disposed on or above the light source, a light reflecting layer disposed on or above the light transmissive member, and a light transmissive cover member. The cover member is made of a resin material containing a light reflecting substance and covers a lateral face of the light source. The light transmissive cover member covers at least a lateral face of the light transmissive member and includes an annular lens part. A thickness of a portion of the light transmissive cover member disposed above a perimeter of the light reflecting layer is larger than a thickness of a portion of the light transmissive cover member disposed above a portion of the light reflecting layer where an optical axis of the light emitting element passes through.
