ABSTRACT:
A composite optical lens is disclosed. The composite optical lens includes a concave bottom surface adapted to receive light, reflective surface adapted to reflect the received light, and optical surface through which the reflected light leaves the optical lens. The concave bottom surface defines a concave cavity allowing placement of at least a portion of a light emitting device within the concave cavity. The concave bottom surface, the optical surface, or both may have predetermined optical finish to operate on the light such as diffusing or focusing the light. The reflective surface can be coated, designed, or both for total internal reflection effect.
