PRIMARY OPTIC FOR A LIGHT EMITTING DIODE

摘要

A special reflector system is integrated with a cover element as part of an LED package. The device supports wavelength shifting medium and highly efficient light coupling to output beams including low divergence beams. The reflector is made at a surface which provides a high-low index mismatch to set up a total internal reflection in a conic section shaped area. The device permits direct on board mounting of semiconductor chips without having to provide for shaped recesses or ancillary reflector systems.
