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 medial reflecting surfaces are configured to redirect light oriented along the linear array into directions that will contribute to a light emission pattern from a warning, signaling or illumination light employing the LED optical assembly. The medial reflecting surfaces cooperate with other reflectors and/or lenses to integrate the redirected light into an intended light emission pattern.
