Appl. No.:

11/961364

Inventors:

Douglas Adams - Raleigh NC, US
Robert L. Wood - Cary NC, US
Edward Fadel - Hillsborough NC, US
Donald Hirsh - Chapel Hill NC, US
Sean Hillard - Raleigh NC, US

Assignee:

Bright View Technologies, Inc. - Morrisville NC

International Classification:

G03B 21/60

US Classification:

359461

Abstract:

Portable projection screen assemblies include a case comprising a flexible projector screen held on a roller, the screen has a high ARR and a high-gain and can be adapted for use in uncontrolled indoor ambient lighting conditions. The case is configured with releasably matable first and second housing members and a slidably collapsible frame that slides open in a side-to-side orientation and unrolls the projector screen to at least one predetermined viewing configuration and closes together to encase the screen and frame therein. The projector screens may be particularly suitable for use with low-lumen projectors.

Assignee:

Bright View Technologies, Inc. - Morrisville NC

International Classification:

G03B 21/56

US Classification:

359443, 359449

Abstract:

Portable front projection screens include: (a) a first panel having opposing primary outer and inner surfaces, the first panel having at least first and second portions that are foldable relative to each other so as to be oriented at an angle relative to each other in an open configuration and closed to a coplanar flat configuration; and (b) a second panel foldably attached to the first panel and having opposing outer and inner primary surfaces. The second panel inner surface comprises a high gain, high Ambient Rejection Ratio projection screen that extends over a major portion of the inner surface. In a closed configuration, the first and second panels reside adjacent and substantially parallel to each other. The first and second panels cooperate to open to a user viewing configuration whereby the second panel is substantially vertical with the projection screen oriented to face forward toward a user and the second portion of the first panel defines a substantially horizontal base with the first portion of the first panel angled upwardly and inwardly from the horizontal base toward the substantially vertical second panel.

Appl. No.:

12/992231

Inventors:

Donald G. Hirsh - Chapel Hill NC, US
Matthew Sean Hilliard - Raleigh NC, US

International Classification:

H01R 13/66
H01R 33/22

US Classification:

43962002, 439664

Abstract:

The disclosure describes devices that are used in conjunction with a pair of (single wattage) compact fluorescent lamps (CFL). In some embodiments, the devices can emulate the behavior of a 3-way incandescent bulb used in a standard 3-way lamp socket. Such can allows people to retain the benefits of their existing Edison-base (E26d) 3-way lamps with the improved energy efficiency and color temperature of modern CFL technology in a cost effective and flexible way. Light fixture conversion kits for allowing an incandescent lamp to accept CFL bulbs are also described.

International Classification:

F21V 29/00
F28F 7/00

US Classification:

362294, 165185

Abstract:

Lighting fixtures using light-emitting devices are disclosed with heat sinks that are both decorative and functional by providing heat dissipation for the light-emitting devices used therein. A luminaire can feature a base for attachment to a support and a driver positionable in the base. An electrical connector can extend downward from the base and have a proximal end and a distal end with the proximal end disposed in the base and engaging the driver. A heat sink can be disposed at the distal end of the electrical connector with the electrical connector extending through the heat sink. A light-emitting device can be attached to the heat sink and connect with the electrical connector such that the driver is electrically connected to the light-emitting device. A lamp shade can be secured to the heat sink proximal to the base with the light-emitting device disposed within the lamp shade and at least a portion of the body of the heat sink forming a decorative portion extending outward from the lamp shade.

International Classification:

F21V 5/00
H05K 13/00
F21S 4/00

US Classification:

362235, 36224902, 295921

Abstract:

A light emitting device assembly can include a plurality of substrates, extending in a longitudinal direction, that are coupled together to provide a plurality of surfaces that face in respective radial directions that are orthogonal to the longitudinal direction. A heat sink can be coupled to the plurality of substrates, and the heat sink can extend radially from the plurality of substrates and is configured to transfer heat away from the plurality of substrates.
