WIDE EMISSION ANGLE LED PACKAGE WITH REMOTE PHOSPHOR COMPONENT

摘要

An improved approach is provided for implementing LED lighting systems and lamps that address the issues identified above. A new type of LED package is disclosed that reduces manufacturing and production costs, while simultaneously allowing for improved thermal management and wide angle light distribution. A self-contained LED package is disclosed that can be mounted as an entire unit onto a lamp platform. The LED package permits the dimensional configuration of the package components to be aligned with desired emission angles. For example, overhangs between phosphor components and circuit boards in the package can be avoided, thereby ensuring that the final lighting system will provide any desired emission angles.

1. An LED package, comprising:
a substrate having an outer substrate edge; an array of one or more LEDs mounted on the substrate; and a photoluminescence component comprising a photoluminescence material, wherein the photoluminescence component is remote from and encloses the array of one or more LEDs; the photoluminescence component having a surface with an outer component edge, wherein the outer component edge is aligned with or extends beyond the outer substrate edge such that the package produces light emission angles from the photoluminescence component at greater than 180 degrees.
