Abstract
An illumination package is disclosed in the invention. The illumination package includes an optical element, package base, and a light emitter. The optical element is designed to redirect a majority of light emitted from the light emitter to a direction approximately perpendicular to a longitudinal axis of the optical element. In one embodiment, the optical element includes an flared portion and a base portion. The flared portion is constructed by an upper surface forming a recess, a side surface adjacent to the upper surface and curved, and a lower surface connecting to the base portion. In another embodiment, a concave lens is formed on the upper surface.
Claims19
An optical element comprised of a light-pervious material, comprising:
- a base portion having a terrace;
- a flared portion protruding from said base portion and constructed from an upper surface forming a recess and having a proximal end and a distal end, a side surface, and a lower surface;
- and
- wherein said upper surface is substantially parallel to or departs far from said lower surface along a path from said proximal end to said distal end, one end of the lower surface of the flared portion neighbors the proximal end of the flared portion, and said upper surface and said lower surface are curved to the same direction.
An optical element comprised of a light-pervious material, comprising:
- a base portion having a terrace;
- a flared portion protruding from said base portion and constructed from an upper surface forming a recess and having a proximal end and a distal end, a side surface, and a lower surface;
- and
- wherein said upper surface is substantially parallel to or departs far from said lower surface along a oath from said proximal end to said distal end, one end of the lower surface of the flared portion neighbors the proximal end of the flared portion, and said side surface is substantially faced upward.
An optical element comprised of a light-pervious material, comprising:
- a base portion having a terrace;
- a flared portion protruding from said base portion and constructed from an upper surface forming a recess and having a proximal end and a distal end, a side surface, and a lower surface;
- and
- wherein said upper surface is substantially parallel to or departs far from said lower surface along a path from said proximal end to said distal end, one end of the lower surface of the flared portion neighbors the proximal end of the flared portion, and said side surface is obliquely angled with respect to a longitudinal axis substantially perpendicular to a bottom surface of said base portion.
