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 light guide array with a retroreflective element used to redirect light into the light guide array, 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. Light emitted by the LED module propagates through the light guide array and is redirected by the light guide array into the environment of the fixture. To prevent light from propagating through the end of the light guide array opposite the LED module, the light guide array can include angled facets forming a retroreflective element at an end of the light guide array for redirecting light back into the LGA.

摘要: A valve assembly for controlling fluid flow includes a valve plate and a nozzle plate which are not attached to each other but can be moved into and out of contact with each other. The valve plate has an opening for passing an actuator and fluid. A nozzle plate has an opening for passing fluid and the opening is aligned with a mesa on the valve plate which can seal the nozzle orifice. The actuator separates the nozzle plate from the valve plate to permit fluid flow and a spring means brings the nozzle plate into a closed position against the valve plate to stop fluid flow.
