Abstract
An LED illumination module including an LED lamp with a plurality of light emitting dies on a substrate in combination with an optic having a single focus. The light emitting dies include a single center light emitting die centered on an optical axis and peripheral dies arranged around the center die. The illumination module includes a beam forming optic having a single focus arranged over the LED lamp with the focus on the optical axis of the center die. Light emitted from the center die is substantially collimated by the optic in a focused 'spot' emission pattern. Light emitted from the peripheral dies results in a more dispersed or divergent 'flood' emission pattern. The center die and peripheral dies are independently controlled and the power delivered to the dies can be varied independently to generate different light emission patterns using the same optic.
