Abstract

A light emitting device includes a light emitting element, a cap sealing the light emitting element, and a light conversion structural section covering an upper surface of the cap. The cap includes a base section having a hole for taking out light emitted from the light emitting element, and a glass section overlaid on the hole. The glass section is provided outside the base section, and the light conversion structural section is provided outside the glass section. According to this light emitting device, manufacturing cost can be reduced by suppressing reduction in yield.

Claims (14)

1. A light emitting device, comprising:

a light emitting element;

a cap sealing said light emitting element; and

a light conversion structural section covering an upper surface of said cap,

wherein said cap includes a base section having a hole for taking out light emitted from said light emitting element, and a glass section overlaid on said hole,

said glass section is provided outside said base section, and

said light conversion structural section is provided outside said glass section.

2. The light emitting device according to claim 1 , wherein

said light conversion structural section is a resin mold containing a phosphor, and

said light emitting element emits excitation light exciting said phosphor.

3. The light emitting device according to claim 1 , wherein said light emitting element is a semiconductor laser element.

4. The light emitting device according to claim 1 , wherein the hole in the base section is formed in a flat surface region of the base section, and the glass section has an area larger than an area of said hole.

5. The light emitting device according to claim 1 , wherein said light conversion structural section entirely covers said cap.
