Appl. No.:

12/757310

Inventors:

Deeder Aurongzeb - Mayfield Heights OH, US
Thomas Alexander Knapp - Cleveland OH, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

F21S 4/00

US Classification:

36224904, 36224903, 362 84, 36224908, 362414

Abstract:

A luminaire, such as a lamp assembly or a floor lamp, umbrella, or planar or sheet-like like light emitting surface includes a conforming mechanism for selectively curving the light emitting surface. A convex profile will diffuse light while a concave profile will concentrate light, it being intended that the surface can be conformable up to a five inch (5″) radius of curvature in either direction. The light panel portions may be of the same color, or may be different colors that will result in different mixing of the light when made from different colors.

International Classification:

H01L 51/52

US Classification:

257 98, 257E51018

Abstract:

An OLED assembly comprises a base and a planar OLED device mounted on the base. A planar light diffuser sheet is removably attached relative to the base and OLED device. A releasable attachment mechanism is operably configured between the light diffuser sheet and the base. The light diffuser sheet is oriented relative to the OLED device so as to provide a selected diffusive property to light emitted from the OLED device. The light diffuser sheet is removable from the base upon release of the attachment mechanism and can be substituted with a different light diffuser sheet. A luminaire may incorporate the OLED assembly, wherein the luminaire has fixture in which the OLED assembly is received.

GE LIGHTING SOLUTIONS, LLC - Cleveland OH

International Classification:

F21V 7/00
F21V 29/00
F21V 5/04

US Classification:

362609

Abstract:

An edge lit luminaire includes a light source. A housing has an interior cavity for receiving the light source. The housing includes a heat sink for directing heat away from the light source. At least one optional end cap is secured to an end of the housing that covers the cavity. A lightguide is secured inside the housing and has an edge located in proximity to the light source. At least one of a reflector and a lens (e.g., lens optic) directs light from the light source to the edge of the lightguide. The lightguide includes a light extraction surface enabling light to be transmitted from the lightguide. The housing can also feature a channel and slot for mounting the luminaire to a support surface. The lens optic can be designed to have specific dimensions that facilitate efficient design and operation of the luminaire.

International Classification:

H05B 37/02
F21V 33/00
F21V 8/00

US Classification:

315158, 362602, 315307

Abstract:

A luminaire is provided that is configured as a window having a light guide with one or more light sources coupled to one or more edges of the light guide. Light emitted from the light guide can be used e.g., to supplement natural light passing through the window or to provide illumination when natural light is not available. Because the light source (or light sources) is incorporated into the window along one or more edges of the light guide, the light source can be either partially or totally concealed from view so as to create an appearance that can have aesthetic advantages. For example, exemplary embodiments of the present invention can have an appearance that is the same or similar to a conventional window/skylight.
