摘要： A light-emitting diode (LED)-based solid-state lamp (LED lamp) comprising four input ports, two bridge rectifiers, two interface modules, an LED driving circuit, and LED arrays operates normally for an input voltage applied from any two of the input ports without operational uncertainty and a fire hazard. The LED driving circuit is configured to provide a regulated power and current to drive the LED arrays. With a cycle-by-cycle triac switching and current control, an over-rated surge current is limited, preventing any fire hazards possibly occurred in the ballast when operated with the LED lamp. With various electrical connection terminals, the lamp can fit and operate in various lamp fixtures comprising two-pin, four-pin, or Edison-base sockets.

摘要： The dual-purpose adapter for inspecting circular (plug-type or receptacle-type) ruggedized fiber optic connector has a guide and a fitting tip. The guide is formed by fastening a template inserter to a frame in two alternative opposite directions. The template inserter has light channels corresponding in relative positions to the endfaces in the ruggedized connector, and two locating holes for coupling and aligning with the ruggedized connector through two guide pins. Depending upon the direction in which the template inserter is fastened to the frame, the fitting tip may be inserted into a respective end of the light channels to allow the optical axis of an inspector probe connected to it to intersect at right angle with PC or APC endfaces for inspection by the inspector probe. For receptacle-type connectors, the guide further includes the two guide pins which can be locked from axial movement at two positions.

摘要： The MT ferrule adapter for adapting an MT ferrule assembly into an MPO connector-type structure for endface inspection includes an upper jaw and a lower jaw rotatable relative to each other between an open position and a closed position. In the open position, the MT ferrule of the MT ferrule assembly can pass through the rear end of the MT ferrule adapter to be received in upper recesses of the lower jaw. In the closed position, the MT ferrule is fixedly held between lower recesses of the upper jaw and the upper recesses of the lower jaw with the front surface of the MT ferrule protruding out in front of the MT ferrule adapter. The MT ferrule adapter in the closed position has the same outer contour as MPO connectors so that the MT ferrule held in the MT ferrule adapter may be inspected by conventional MPO connector inspectors.

摘要： Embodiments of an optical assembly for use in polarization rotation applications are disclosed. In one aspect, an optical assembly includes a polarization beam splitter a rotational element and a path exchange mirror. The temperature, wavelength and manufacturing dependencies of polarization rotation of this optical assembly are minimal to nonexistent compared to conventional Faraday rotation assemblies as the optical fiber accepts only the desired rotation. As such these optical assemblies have no temperature and wavelength dependencies of the polarization rotation angle over broad temperature and wavelength ranges with minimal additional losses. In another aspect, the polarization dependence of reflection from the path exchange mirror is managed so as to minimize the polarization effect associated with oblique incidence.

摘要： A dimming and CCT tuning system comprises a controller and multiple LED-based lighting devices. Each lighting device comprises a control circuit, at least two LED driving circuits, and at least two types of LED-based light sources. When the controller receives the dimming and CCT tuning signals from its inputs, it generates a modulated dimming and CCT tuning signal portion in the AC voltage delivered to the multiple lighting devices. Afterwards, a regular AC power is delivered. In receiving, each lighting device demodulates such signal portion and generates at least two control signals to the at least two LED driving circuits which then individually power the at least two types of LED-based light sources to emit desired light levels and CCTs. The system eliminates extra wires required in 0-10 V dimming control and maintains an undistorted AC waveform in most of operating time, not like a TRIAC dimming.

摘要： A linear light-emitting diode (LED)-based solid-state lamp using an AC current control scheme and shock protection switches operates normally with an electronic ballast. Due to the use of shock protection switches in the two lamp bases at two opposite ends, the ballast-compatible LED lamp fully protects a person from possible electric shock during initial installation, maintenance, and re-lamping no matter what the rated power and the brand of the LLT lamp are and no matter whether the electronic ballast is existing used ones that may be incompatible with the lamp or faulty, leading to an unacceptable leakage current.
