摘要： An optical device for coupling the luminous output of a light-emitting diode (LED) to a predominantly spherical pattern comprises a transfer section that receives the LED’s light within it and an ejector atop it that receives light from the transfer section and spreads it spherically. The base of the transfer section is optically coupled to the LED so that the LED’s light goes inside the transfer section, which comprises a compound elliptic concentrator operating via total internal reflection. The ejector section can have a variety of shapes, and can have diffusive features on its surface as well. The device is circularly symmetric, with a height preferably only a few times its diameter. An important application is for use at the focus of the parabolic reflectors in flashlights. This version of the invention further comprises a base-can identical in outer shape and electric contacts to those of flashlight bulbs. Within the can is the current-control circuitry the interfaces the LED with battery voltage. Another version uses half a transfer section at each end of a long cylindrical ejector, illuminated by an LED at both ends. Ejection is via internal scattering by controlled sub-wavelength roughness. In one cylindrical embodiment, diffuse reflectivity varies from one third at the ends to two thirds at center.

The beam-expanding ejector comprising a planar waveguide optically coupled to the output port of the injector. The ejector includes a smooth upper surface, and a reflective lower surface comprising microstructured facets that refract upwardly reflected light into a collimated direction common to the facets.
