Patent ID: 7967478

Claim:
A device for redistributing light emitted by an LED, the device comprising an optical element for reflecting and refracting the light emitted by the LED, wherein a lower profile of the optical element defines a first surface by revolution around an axis of symmetry, the first surface having a conical cavity with a vertex pointing away from a primary lens of the LED, wherein an upper profile of the optical element defines a second surface by revolution around the axis of symmetry, the second surface having a cavity with a vertex pointing toward the primary lens of the LED, wherein a side profile of the optical element defines a third surface by revolution around the axis of symmetry, the third surface being a cone frustum-shaped solid narrowing toward the primary lens of the LED, wherein the device rotates an optical axis of the light emitted from the LED by 90°, and wherein the optical element varies emission angles of the light emitted from the LED relative to the axis of symmetry.
