    摘要： An optical emitter enabling conversion of light from a light source. The optical emitter includes a first conic reflector defining an aperture for receiving the light source, a second conic reflector opposite the first conic reflector for collimating light emitted by the light source, and a volumetric light conversion element between at least a portion of the first reflector and at least a portion of the second reflector. The optical emitter can also include a convex mirror adjacent the vertex of the second conic reflector, and an elliptical element adjacent the first conic reflector. The light conversion element can include phosphor dispersed in a resin to convert light from a first wavelength to light of a second, longer, wavelength, wherein converted light is emitted from the light conversion element.

    摘要： An optical coupling device enabling spherical or hemispherical light sources to be more fully utilized by gathering more of the emitted radiation and reducing the angle of emission. The optical coupling device includes a first conic reflector having an aperture at the first conic reflector vertex; a second conic reflector coaxial with the first conic reflector and opening toward the first conic reflector; a light source positioned at the second conic reflector vertex; and a negative element located at the aperture for reducing the numerical aperture of the light emitted from the optical coupling device. The optical coupling device may include a refractive medium between the first and second conic reflectors. The present invention provides for improved efficiencies when transferring or coupling optical energy into additional optical systems, and may be used with solid state light as well as conventional sources.
