A halogen infrared lamp () having an infrared reflective coating () along with a totally reflecting coating () on ends of an ellipsoidal portion of the envelope. The totally reflecting coating reflects the infrared radiation escaping at acute angles and directs the infrared radiation towards the filament to increase the temperature of the filament and thus increase the efficacy of the lamp. The totally reflecting coating may also extend to portions of tubular members extending from the ellipsoidal portion of the envelope.

An environmentally favorable method is described for treating an incandescent lamp with a heat curable substantially organic solvent free silicone composition to improve the shatter resistance of the lamp.

There is provided an emissive mixture for cathodes of fluorescent lamps comprising a ceramic material having a formula (A Ca ) (Ta W ) O , where A is barium or a combination of barium and strontium, 0&lE;x<0.5, 0&lE;y<1, and one of x or y is greater than zero. The ratio of lamp efficacy to number of lamp starts may be improved by optimizing the amount of Ca and W present in the ceramic material.

A system and method for generating ultrasonic displacements on a remote target. The method of the present invention includes the steps of first using a laser to generate a beam having a first wavelength to produce ultrasonic displacements at the remote target. This laser beam will have a first wavelength which can be modulated to alter characteristics of the ultrasonic displacements. These ultrasonic displacements at the remote target can be optimized to enhance the detection optics for collecting phase modulated light from the second pulsed laser beam either reflected or scattered by the remote target; an interferometer to process the phase modulated light and generate at least one output signal, and means for processing the at least one output signal to obtain data representative of the ultrasonic surface displacements on the surface of the remote target.

A back-light assembly for a liquid crystal display (LCD) includes an LCD display screen and at least one cold cathode fluorescent lamp positioned for illuminating a back-side of the display screen. A reflector positioned adjacent the lamp reflects light toward the display screen. A light diffuser is positioned between the lamp and the display screen; and a power controller regulates current supplied to the lamp from an external power source so as to establish a predetermined luminance level at the display screen. A light level sensor provides a signal representative of the luminance output of the lamp to the controller so as to regulate lamp current to maintain the predetermined luminance level.

A lamp assembly comprises a incandescent lamp capable of generating light. The incandescent lamp comprises a incandescent lamp tube and at least one filament. The assembly also comprises a shroud separate from the incandescent lamp and mounted in communication with the lamp tube on an exterior of the incandescent lamp tube. The shroud also comprises a coating disposed on the reflecting section of the shroud for reflecting energy having predetermined wavelengths emitted by the incandescent lamp. The shroud comprises a reflecting section disposed about the incandescent lamp tube, where the geometry of the shroud generally conforms to the geometry of the at least one filament of the lamp, to reflect energy having predetermined wavelengths back substantially toward the incandescent lamp and focusing the reflected energy generally at the at least one filament of the incandescent lamp so as to increase the output from the assembly.

Single-crystal diamond consisting of isotopically pure carbon-12 or carbon-13 has been found to have a thermal conductivity higher than that of any substance previously known, typically at least 40% higher than that of naturally occurring IIA diamond. It may be prepared by a method comprising comminution of diamond of high isotopic purity, such as that obtained by low pressure chemical vapor deposition employing an isotopically pure hydrocarbon in combination with hydrogen, followed by conversion of the comminuted diamond to single-crystal diamond under high pressure conditions.

The invention refers to a filament having improved emission of visible light. The emissivity of a tungsten filament is improved by depositing a layer of submicron-to-micron crystallites on the filament, the layer having substantially submicron spacing between crystallites. The crystallites being formed from tungsten or a tungsten alloy of up to 1 weight percent thorium, up to 10 weight percent of at least one of rhenium, tantalum, or niobium, and the balance substantially tungsten.
