International Classification:

H01K 1/14

US Classification:

313315

Abstract:

A base-up incandescent lamp () includes a coiled-coil filament () that has a primary wire () and a secondary wire (), the primary wire () comprising an overwind that overlies the secondary wire () and provides a lower filament temperature and, therefore, less filament sag and a concomitant longer lamp life.

Abstract:

A PAR lamp () has a body () with an internal reflector surface () disposed about a longitudinal axis (). A cavity () is provided at one end () of the body () and an arc discharge tube () that provides a substantially spherical light source is positioned in the cavity () and disposed on the longitudinal axis (). A cover receiving opening () is provided at a second end () of the body and a cover () closes the cover receiving opening (). A plurality of spiral facets () is formed on the internal reflector surface (), the plurality of spiral facets () being sufficient in number to increase the maximum beam candle power and decrease the beam angle when compared to faceted lamps having a lesser number of facets. The number of facets is equal to or greater than 75 and preferably is 100.

International Classification:

H01J 9/00
H01J 9/34
H01J 9/36

US Classification:

445 22, 445 26, 445 27

Abstract:

An integral HID reflector lamp may be formed with an HID held in a reflector. An inner element is mechanically coupled to the reflector. The inner element is formed with a first mechanical coupling to mate with the reflector, a second mechanical coupling to mate with a circuit board, and an electrical coupling to at least electrically couple one of the leads to the circuit board. A circuit board has an edge mechanically coupled to the inner element and electrically connected to the leads by an electrical coupling on the inner element. A heat sink spans at least one side of the circuit board and forming an EMI shielding. An outer cover encloses the heat sink, circuit board, and inner element and coupled to the assembly of the reflector, HID lamp, inner element, and heat sink with each elements of the assembly clipped together.

International Classification:

A23D 7/00

US Classification:

426602, 426590

Abstract:

It has now been found that emulsions having a discrete phase volume fraction of 60% to 67% with excellent stability may be prepared using at least one low molecular weight surfactant. Such emulsions have high oil loading and a small mean particle size of less than 0. 2 microns. Further, such emulsions may be used in beverages without weighting agents.

Abstract:

A light engine that includes electrical leads extending into a supporting stem and a filament assembly having a V-shaped geometry in electrical connection with the electrical leads. The filament assembly includes at least two light emitting diode (LED) filaments wherein a first end of the filament assembly is in electrical contact with the electrical leads and provides an apex portion of the V-shaped geometry, and a second end of the filament assembly opposite the first end has a second width greater than the first width of the apex portion. An electrically conductive pathway connects the at least two light emitting diode (LED) filaments at the second end of the filament assembly.
