Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

F21V 7/04

US Classification:

362554, 362555, 362580

Abstract:

An illumination system includes a plurality of radiation generating sources, such as LED dies. A corresponding plurality of optical waveguides is also provided, with each waveguide having a first and a second end, with each first end being in optical communication with the corresponding LED die. An array of corresponding passive optical elements is interposed between the plurality of LED dies and the corresponding first ends of the plurality of optical waveguides. The illumination system provides for substantially high light coupling efficiency and an incoherent light output that can appear to the human observer as arising from a single point of light. In addition, the light can be output remotely at one or more locations and in one or more directions.

International Classification:

F21V 7/04

US Classification:

362609, 362560, 362616

Abstract:

An illumination system including a light source, light guides coupled to the light source, each including an input surface and an output surface, emissive material positioned to receive light from at least one light guide, and an interference reflector positioned such that the emissive material is between the output surfaces of the light guides and the interference reflector is disclosed. The light source emits light having a first optical characteristic. The emissive material emits light having a second optical characteristic when illuminated with light having the first optical characteristic. The interference reflector substantially transmits light having the second optical characteristic and substantially reflects light having the first optical characteristic.

International Classification:

G02B 6/00

US Classification:

25022731, 362310

Abstract:

A backlight may include a light guide and a light input. The light guide may have a light reflection surface and a light emission surface. The light input may include a diverging wedge having a narrow end and opposing side surfaces extending to the narrow end. A light source well may be formed in the light input, and a light source may be disposed within the light source well. An encapsulant may be disposed about the light source, within the light source well. A specularly reflective film or layer may be disposed adjacent to but not in intimate contact with the opposing side surfaces and may reflect more than 80% of visible light incident on the multilayer polymeric mirror film.
