    摘要： A lamp has a reflective cup with a light emitting device in the bottom of the cup. A transparent material having an index of refraction n fills the cup and extends to a hemispherical surface with radius R and an equator parallel to the opening of the cup. The reflective walls of the cup project substantially all of the light within a cutoff cone having an included half angle equal to the Brewster's angle of the transparent material. The center of the hemispherical lens surface is spaced from the rim of the opening of the cup a distance R/n. Thus, the opening of the cup is the locus of aplanatic points of the equator if the hemisphere. Most rays from within the cup are incident on the hemispherical lens surface at no more than the complement of the Brewster's angle. Thus, minimal light losses occur at the interface between the transparent medium and air. An aplanatic image is formed outside the hemispherical lens of a virtual source comprising a hemispherical surface extending through the rim of the cup opening. Such optics may also be used for a light accepting device. These principles may also be applicable to a an elongated cavity with a semicylindrical lens of radius R and edges spaced from the edge of the cavity a distance R/n.

    摘要： An assembly of an optical interconnect module adaptable for mating with an optical connector having at least one optical fiber and an alignment pin. A method of assembly includes the steps of (1) mounting an optical device onto a connector body, wherein the connector body is a portion of the optical interconnect module, and wherein the optical device is operable for transmitting or receiving optical signals to/from the optical fiber, (2) inputting a relative position between the alignment pin and an end of the optical fiber, (3) and forming a slot in the connector body by using the measured relative position between the alignment pin and the end of the optical fiber, wherein a relative position between the slot and the optical transceiver mirrors the relative position between the alignment pin and the end of the optical fiber so that the optical device and the end of the optical fiber are substantially aligned to permit transmission of the optical signals when the optical connector and the optical interconnect module are mated, wherein the slot is adaptable for receiving the alignment pin.

    摘要： This is directed to a LED light fixture having a shaped light guide array with a CPC reflector for directing light off-axis, and methods for constructing the same. A LED light fixture includes a LED module providing light and an elongated light guide array placed adjacent to the LED module. The elongated light guide array can include a curved outer surface through which light is emitted into an environment. To further control the output of light, and to direct light off-axis, the light guide array can include a CPC reflector disposed around a boundary or periphery of the light guide array. The CPC reflector can be angled such that light is directed at angles above a cut-off angle by which the reflector is rotated about a focus.
