摘要： A piezoelectric transformer signal coupler utilizes a drive circuit including an oscillator constructed to excite the primary of a piezoelectric transformer at its characteristic anti-resonant frequency. Positive feedback signals modulated by the time domain response characteristic of the particular piezoelectric transformer force the oscillator to lock onto its characteristic anti-resonant frequency despite variations thereof due to temperature drift and secondary loading. The resulting drive circuit is implementable as a miniature, low mass integrated circuit mountable on the transformer's piezoceramic wafer to create a signal coupler of a single integrated structure.

摘要： An alternating current latching relay is provided which employs a latching-type, mechanically operated snap-action switch mechanism with a set of electric contacts that are selectively latched either in the open or closed condition in a snap-action manner upon successive actuations of the snap-action mechanism by suitable push rod means for initiating its operation. At least one alternating current excited bender-type piezoelectric drive member has one end secured to a common base member with the latching-type snap-action switch mechanism and the remaining free end engaging the push rod means. An alternating current electric excitation signal is directly applied to the piezoelectric plate elements of the bender-type drive member for mechanically vibrating the bender-type drive member in a manner such that its amplitude of vibration quickly builds up to a value where it repeatedly strikes the push rod means with sufficient force to selectively actuate the snap-action switch mechanism to the opposite one of its two operating conditions from that in which it originally was set. A tuning mass in the form of a slug element is secured to the end of the bender-type drive member to reduce the natural resonant frequency of vibration of the bender-type drive member to substantially the frequency of the alternating current excitation signal to thereby increase the amplitude of its vibrations to a maximum. Additionally, the tuning mass increases the impulse delivered by the bender-type drive member to the push rod for actuating the snap-action mechanism.

摘要： Miniature high pressure metal vapor lamps containing mercury in a discharge volume of one cubic centimeter or less when operated at low frequencies have extremely high reignition voltages; the problem is compounded in metal halide lamps, particularly during warm-up. Ballast designs capable of coping with these conditions at 60 Hz have disadvantages. The discovery of the existence of resonance-free regions in the frequency range between 20 and 50 KHz has made stable and efficient lamp performance possible through the use of compact, practical and economical high frequency ballasts.

摘要： An elongated LED lighting arrangement comprises an elongated fiberoptic light pipe having an exteriorly facing sidewall between its ends. The light pipe is constructed to promote TIR of light between the ends. A first LED light source is tuned to efficiently provide light within a wavelength range to the pipe. Light-extracting means are applied along the light pipe along the main path of TIR light propagation, and comprise down-converting means tuned to efficiently convert light rays from the LED light source within the wavelength range to lower-energy light rays at respectively longer wavelengths and light-scattering means for extracting from the pipe some light rays within the wavelength range without changing the wavelengths of the foregoing light. The light emitted by the down-converting means and the light-scattering means intermix to produce light, the majority of which has a composite color determined by the foregoing light emitted and the foregoing light extracted.

摘要： Disclosed is an LED fixture with passive cooling. The fixture includes a plurality of elongated tubes, each containing an array of LEDs mounted on a respective first surface or surfaces of one or more circuit boards. A frame mounts to a building structure and holds the ends of the tubes. Each tube is sufficiently spaced from any adjacent tube and from any other structure of the frame, and the frame is sufficiently open at the top and bottom, whereby heat from the tubes is capable of being dissipated merely by passive thermal transfer into an air flow created by the heat of the tubes, which air flow moves from beneath the tubes to above the tubes.

摘要： A light pipe with directional side-light extraction comprises a light pipe and light-extraction structure applied to the light pipe over only a part of the cross-sectional perimeter of the light pipe and over an active section of the length of the light pipe in which directional side lighting is desired. The light-extraction structure comprises any of (i) material, other than a light-carrying portion of the light pipe or any fluoropolymer cladding on the light-carrying portion, including light-scattering material, (ii) surfaces treated to have light-scattering properties, and (iii) material with a reflective property. The foregoing light pipe eliminates the need for using a reflector, as with fluorescent lamps, by extracting the light only in the desired direction, towards a target area to be illuminated. Other embodiments of the invention promote uniformity in side light emission from a light pipe.
