摘要： A light source (10) includes a light emitting component (32), such as a UV/blue light emitting diode or laser diode, a layer (46) of a light scattering material (42), and a layer (48) of a phosphor material (44). The phosphor material converts a portion of the light emitted by the light emitting component to light of a longer wavelength, such as yellow light. The scattering material scatters the light emitted by the light emitting component and/or the light converted by the phosphor to improve the overall uniformity of the angular distribution of the light. When combined, the converted and scattered light has a more uniform angular distribution, that is, it maintains the approximately the same color as the viewing angle is changed.

摘要： A color tunable light source (10) includes multiple light emitting components (32, 34, 36), such as light emitting diodes (LEDs) or laser diodes (LDs) with different emission wavelengths, and multiple phosphors (24) with different excitation and emission wavelengths. The emission wavelengths of the different light emitting components are chosen to match the excitation wavelengths of the different phosphors. The light emitting components are powered by an electrical circuit (42, 44, 46), which allows separate control of the optical power output of the different wavelength LEDs/LDs. The light from the light emitting components is arranged to impinge on the combination of phosphors such that the phosphors are excited and emit light at their characteristic wavelengths. By separately adjusting the power to each LED/LD, the amount of light emitted by each phosphor, and hence, through color mixing, the color of the light emitted, is varied.

摘要： A circuit breaker is equipped with a current limiting arc runner for effective overcurrent interruption without additional heating under quiescent operating conditions. Upon contact separation, an arc is drawn with the endpoints of the arc being initially rooted on the set of open contacts. Further opening of the contacts commutates the arc onto the current limiting arc runner to suppress the circuit current.

摘要： A fault current interrupter is provided by the parallel combination of a polymer current limiter and a voltage dependent resistor connected across a pair of separable contacts to permit the interruption of current without the occurrence of arcing between the contacts when the contacts first become separated. The polymer current limiter is selected to have a relatively low resistance at quiescent operating currents and a substantially higher resistance at short circuit overcurrents. This allows the current to transfer away from the contacts through the polymer current limiter until the voltage across the voltage dependent resistor causes the voltage dependent resistor to become conductive and thereby transfer the current away from the polymer current limiter.

摘要： A current limiting device utilizing an electrically conductive composite material and an inhomogeneous distribution of resistance structure is disclosed. The inhomogeneous distribution is typically chosen so that at least one selected thin layer of the current limiting device has much higher resistance than the rest of the current limiting device. In the actual device, pressure is typically exerted on the composite material in a direction normal to the selected thin layer. During a short-circuit, it is believed that adiabatic resistive heating of this selected thin layer is followed by rapid thermal expansion which leads to either a partial or complete physical separation of the current limiting device at the selected thin layer which produces a higher over-all device resistance to electric current flow. Thus the current limiting device limits the flow of current through the short-circuited current path. When the short-circuit is cleared, the current limiting device regains its low resistance state allowing electrical current to flow normally. The current limiting of the present invention is reusable for many such short circuit conditions.

摘要： A solid state process for the bulk conversion of a dense polycrystalline ceramic body to a single crystal body has been accomplished by heating the polycrystalline material to a temperature above one-half of the melting temperature of the material but below the melting point of the material. As the process is a solid state process, no melting of the ceramic body is necessary to convert it to a single crystal. The process has been used to convert a dense polycrystalline alumina body (PCA) containing less than 100 wppm of magnesia to sapphire (single crystal alumina) by heating the PCA to temperatures above 1100.degree. C. but below 2050.degree. C., the melting point of alumina.

摘要： A solid state method of converting a polycrystalline ceramic body to a single crystal body includes the steps of doping the polycrystalline ceramic material with a conversion-enhancing dopant and then heating the polycrystalline body at a selected temperature for a selected time sufficient to convert the polycrystalline body to a single crystal. The selected temperature is less than the melting temperature of the polycrystalline material and greater than about one-half the melting temperature of the material. In the conversion of polycrystalline alumina to single crystal alumina (sapphire), examples of conversion-enhancing dopants include cations having a +3 valence, such as chromium, gallium, and titanium. The polycrystalline body further can be inhomogeneously doped to form a first portion of the polycrystalline body that is doped to the selected level of the conversion-enhancing dopant and a second portion that is not doped such that heating the doped polycrystalline body causes conversion of first portion to a single crystal structure and the second portion retains a polycrystalline structure.
