Abstract: A light weight and modular light emitting diode (LED) light bar comprising an extruded aluminum LED fixture frame with integral cooling fins is disclosed herein. The light bar of the present invention is used for high density multi-layer hydroponic grow facilities to greatly improve the uniformity and intensity of light distribution over the plants and at a much reduced energy cost and less heat-to-space compared to conventional lighting used in grow rooms.

Abstract: Embodiments provide an LED comprising a quantum well region operable to generate light and a substrate having an interface with the quantum well region, wherein light generated by the quantum well region traverses the interface to enter the substrate and exit the LED through an exit face of the substrate. The exit face may be opposite from and a distance from the interface, with some portion or all of this LED being shaped to optimize the light extraction efficiency of the device. The exit face can have at least 70% of a minimum area necessary to conserve brightness for a desired half-angle of light. Sidewalls of the LED may be positioned and shaped so that rays incident on a sidewall reflect to the exit face with an angle of incidence at the exit face at less than or equal to a critical angle at the exit face.

Abstract: Embodiments of the present invention provide separate optical devices operable to couple to a separate LED, the separate optical device comprising an entrance surface to receive light from a separate LED when the separate optical device is coupled to the separate LED, an exit surface opposite from and a distance from the entrance surface and a set of sidewalls. The exit surface has at least a minimum area necessary to conserve brightness for a desired half-angle of light projected from the separate optical device. Furthermore, each sidewall is positioned and shaped so that at least a majority of rays having a straight transmission path from the entrance surface to that sidewall reflect to the exit surface with an angle of incidence at the exit surface at less than or equal to a critical angle at the exit surface.

Abstract: An optical connector for terminating an optical fiber comprises a housing configured to mate with a receptacle and a collar body disposed in the housing. The collar body includes a fiber stub disposed in a first portion of the collar body, the fiber stub including a first optical fiber mounted in a ferrule and having a first end proximate to an end face of the ferrule and a second end. The collar body also includes a mechanical splice disposed in a second portion of the collar body, the mechanical splice configured to splice the second end of the fiber stub to a second optical fiber. The collar body also includes a buffer clamp configured within a third portion of the collar body, the buffer clamp configured to clamp at least a portion of a buffer cladding of the second fiber upon actuation. A fiber distribution unit is also provided.

Abstract: A field termination platform and method for field termination of an optical fiber in an optical fiber connector are provided. The field termination platform includes a base configured to hold the optical fiber connector having a pre-assembled fiber stub. An actuation mechanism is disposed on the base to actuate a splice element of the optical connector and to actuate a buffer clamping portion of the optical connector. A fiber holder is provided to hold the optical fiber in the termination platform during termination.

Abstract: A splice holder device includes a tray mountable in a telecommunications closure, the tray including a splice mounting mechanism configured to receive a splice device. The splice holder device also includes first and second fiber clamps disposed on the tray, wherein the first and second fiber clamps are each configured to releasably secure a buffered portion of an optical fiber. The tray can include a single splice device, such as a mechanical splice, mounted therein or can include a plurality of splice devices mounted therein. The splice holder device can be configured to be securedly mounted in a telecommunications enclosure.

Abstract: A digital film processing system and film processing solution or development cartridge are disclosed. The cartridge comprises a housing and a chamber for storing a film processing fluid. The cartridge may also include an applicator nozzle for coating the processing solution onto undeveloped film. The system includes a cleaning and capping device or arrangement that is adapted to clean and seal an opening of the applicator nozzle.
