| description | A light emitting device includes a light emitting element on a substrate, and a lens element that includes a cavity within which the light emitting element is situated, and is optically aligned with the light emitting element. A strip of adhesive that attaches the lens element to the substrate substantially surrounds the light emitting element, but includes a gap that facilitates release of material from the cavity during the attachment of the lens element to the substrate. When the lens element is placed upon the substrate, the adhesive is partially cured to provide a relatively high shear strength before the light emitting device is transported or subjected to other processes. To provide compatibility with subsequent processes or applications, and to protect the light emitting element from the environment, the gap in each device is sealed with a sealing material. |
