Abstract
An LED optical assembly includes a linear array of LEDs, longitudinal reflecting surfaces along each side of the array and medial reflecting surfaces between the LEDs. The longitudinal reflecting surfaces include surfaces of rotation centered on the optical axis of each LED interspersed with linear reflecting portions defined by curves projected along a linear focal axis of the assembly.
