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.
