Abstract
Optical elements for semiconductor light emitting devices include a body that is configured to attach to a semiconductor light emitting device. The body includes an integral lens. A mirror is provided in and/or on the body. The body, the lens and the mirror are positioned such that, in operation, light that is emitted from the semiconductor light emitting device enters the body, is reflected from the mirror and passes through the lens to emerge from the body.
Claims35
An optical element for a semiconductor light emitting device, comprising:
- a body that is configured to attach to a semiconductor light emitting device and that includes a lens integral therewith;
- and
- a mirror that is in the body;
- the body, the lens and the mirror being positioned such that, in operation, light that is emitted from the semiconductor light emitting device enters the body, is reflected from the mirror and passes through the lens to emerge from the body;
- wherein the mirror comprises a reflective plug that extends in the body.
An optical element for a semiconductor light emitting device comprising:
- a body that is transparent to optical radiation from a semiconductor light emitting device, the body including a base that is configured to attach to a semiconductor light emitting device, a cavity that is remote from the base and that defines a cavity surface and a lens element on a surface of the body between the base and the cavity;
- and
- a mirror on at least a portion of the cavity surface;
- wherein the mirror comprises a reflective plug in the cavity.
An optical element for a semiconductor light emitting device comprising:
- a truncated spherical body that is transparent to optical radiation from a semiconductor light emitting device, the truncated spherical body including a base that is configured to attach to a semiconductor light emitting device, and an inverted conical cavity that is remote from the base and that defines an inverted conical cavity surface;
- and
- an inverted conical mirror on the inverted conical cavity surface.
An optical element for a semiconductor light emitting device, comprising:
- a body that is configured to attach to a semiconductor light emitting device and that includes a lens integral therewith;
- and
- a V-shaped mirror that is in and/or on the body;
- the body, the lens and the V-shaped mirror being positioned such that, in operation, light that is emitted from the semiconductor light emitting device enters the body, is reflected from the V-shaped mirror and passes through the lens to emerge from the body as two beams.
