| 发明名称 | Light-emitting device | ||
| 摘要 | A light-emitting device includes a phosphor plate including an upper surface, a lower surface opposite to the upper surface, a peripheral side surface extending between a peripheral edge of the upper surface and a peripheral edge of the lower surface of the phosphor plate, a light-emitting element including an upper surface, a lower surface opposite to the upper surface, a peripheral side surface extending between a peripheral edge of the upper surface and a peripheral edge of the lower surface of the light-emitting element. The lower surface of the phosphor plate includes a concave that is filled with an adhesive and the lower surface of the phosphor plate is disposed on the upper surface of the light-emitting element. The phosphor plate may contain a first phosphor, and the adhesive filled in the concave that is provided at the lower surface of the phosphor plate may include a second phosphor. | ||
