Abstract
A method for high-volume production of light emitting diodes with attached lenses involves providing pre-fabricated lenses, wherein the pre-fabricated lenses are held by a common transfer structure, simultaneously attaching the pre-fabricated lenses to respective ones of light emitting diodes, and releasing the pre-fabricated lenses from the common transfer structure. In an embodiment, the light emitting diodes are distributed in a pattern on a common substrate and the common transfer structure is configured to hold the pre-fabricated lenses in a pattern that corresponds to the pattern of the light emitting diodes on the common substrate. Further, to attach the pre-fabricated lenses to the light emitting diodes, the common transfer structure is positioned relative to the common substrate such that the pre-fabricated lenses are aligned with the light emitting diodes.
